Description

  The present invention is to bury buried objects such as pipes and wiring in the ground, or to inspect, repair, and refill the buried objects in the ground, leveling, and paving. The present invention relates to a technology for supporting the restoration work when the restoration work for restoring the ground surface is performed.

Conventionally, for example, when performing buried object construction, firstly, a buried company such as a gas company that operates buried objects such as gas pipes,
<1> Based on the survey design, etc.
<2> Accumulate and present the contents of the construction commanded as the buried construction plan, select the buried construction company, and place an order.
after that,
<3> After conducting discussions and application with the government and other organizations,
<4> The buried construction company will proceed with buried construction work,
<5> After completion of the construction of buried objects, the management company will inspect and inspect it.
This completes the construction work for buried objects.
In addition, asset managers
<6> Based on the construction drawings at the time of completion of the buried construction work, create a restoration work plan drawing,
<7> Accumulate and present the contents of the restoration work commanded as the restoration work plan drawing, select the restoration work company, and place an order.
after that,
<8> After consulting and applying with the government and other organizations,
<9> The restoration company will proceed with restoration work.
<10> After the restoration work is completed, the management company accepts the product after inspection.
This completes the restoration work and finishes the buried work.

  At this time, the management company is mainly involved in the steps <1>, <2>, <3>, <5>, <6>, <7>, <8>, <10>. However, in other processes, a construction company different from the asset management company is responsible for the work, and also in the construction company, the buried construction company and the restoration construction company are different, or multiple buried construction companies share the work. In many cases, multiple construction companies are involved, and many people are involved in the construction. For this reason, in order to transmit the details of the construction accurately and promptly, it requires strict attention, requires a lot of labor, and may be difficult. Also, during the processes <3>, <4>, <8>, and <9>, the actual work contents of the construction may be changed or added, and particularly the above <3> and <4>. If the differences to the buried work plan such as changes and additions of buried work contents in this process are not accurately communicated to the subsequent workers, the subsequent processes will be delayed and may not be performed smoothly. Effect.

  In order to avoid such an influence, it is possible to use a data management system that is shared by multiple workers to make it possible to quickly and accurately grasp the actual work in the process from the construction plan drawing to the completion of the construction drawing. (For example, refer to Patent Document 1).

JP 2002-297852 A

However, burial works companies that carry out burial work rarely make construction drawings while carrying out burial work, and in fact, during the burial work, construction workers at the burial work site are The actual construction work is carried out while manually correcting the buried construction plan drawing given in the above, and the buried construction plan drawing with the handwritten correction or the construction drawing that has been clarified is used as it is when the buried construction work is completed. It is used for acceptance inspection.
Then, such drawings are often unclear except for the person who corrected the handwriting, and there is often a doubt about the accuracy of the drawing because there is a time from handwriting correction to clean-up. . For this reason, the inspection worker must actually go to the buried construction work site, inspect the buried construction in the process <5>, or plan the restoration work in the process <6>.

  Then, the construction drawings that reflect the differences in the buried work at the completion of the construction are those that the restoration work plan drawing creator cannot easily refer to, or it will take time to complete, so the restoration work plan There is a problem that it takes time to start creating a drawing, and eventually delays construction work. In addition, there will be a delay in the work of totaling and placing orders for restoration works in the above process <7> and ordering for consultations on the restoration work in the process <8>, which will be performed using this restoration work plan drawing. There is a fact that the drawings are difficult to use even if they are presented to each construction company or the government concerned with the construction. Therefore, as construction drawings at the time of completion of construction, it is accurately converted into data so that it can be easily referred to by workers in the subsequent process, created immediately upon completion of construction and not obstructing the progress of construction, It is desirable that a person can easily refer to it.

  In addition, by creating a construction plan drawing using the construction plan drawing as a construction drawing, making corrections in consideration of the differences in the construction work of <3> and <4> above, and creating a construction drawing, In particular, the step <6> can be performed quickly. Therefore, the restoration work plan drawing creator often performs a process of creating the construction drawing while referring to the construction plan drawing.

  Then, even if the creator of the drawing can grasp the difference in the buried work in the processes <3> and <4>, it surely grasps the correspondence between the construction drawing and the restoration work plan drawing. For this reason, it is complicated and difficult to accurately create and modify a restoration work plan drawing while making both drawings correspond to each other, and a great deal of labor is required.

  Therefore, an object of the present invention is to provide a technique for supporting the work related to the above-described restoration work so that the work can be performed smoothly.

The characteristic configuration of the restoration work support system of the present invention is:
A restoration work support system that supports restoration work to restore the ground surface after buried work of buried objects buried in the ground,
In the state where the construction drawings stored in the storage unit are displayed, a restoration construction plan drawing for creating a restoration construction plan drawing for performing the restoration construction on the construction drawing or in association with the construction drawing is provided, An output means for outputting the restoration work plan drawing to an external terminal is provided.

  That is, with the construction drawing displayed, the construction drawing is referred to and the restoration construction plan drawing is created on the construction drawing. Therefore, the restoration construction plan drawing can be created while being associated with the construction drawing. Therefore, the restoration work plan drawing creator can create the restoration construction plan drawing while easily grasping the correspondence relationship between the construction drawing and the restoration construction plan drawing, and quickly and accurately create the restoration construction plan drawing. Can help. Therefore, it is possible to perform the drawing while easily optimizing the area related to the restoration work and the minimum necessary materials. Further, since the restoration work plan drawing created in this way is outputted to the external terminal by the output means, necessary materials, expenses, etc. can be calculated based on the output result. For this reason, it is possible to further assist such a business in which a construction company makes a bid by referring to such information.

  The restoration work plan drawing creation means is realized by a computer executing a predetermined program, reads a construction drawing stored in a construction drawing database or the like, displays it on the screen, and in accordance with an input command by a drafter. It is configured to draw on the screen display. The restoration work plan drawing obtained in this way may be created so that the restoration work plan drawing can be obtained by overwriting the construction drawing data, or added as a different layer to the construction drawing data. It may be created so that it can be obtained in a state in which it is obtained, or it may be created so that a restoration work plan drawing is obtained as another data in a state associated with the construction drawing.

  Further, in addition to the above-described configuration, it is preferable to provide construction drawing creation means for creating a construction drawing by correcting the buried construction plan drawing created based on the buried construction plan based on the actual construction work.

  That is, according to the construction drawing creation means, the difference between the actual construction work of the buried construction and the buried construction plan can be reflected and corrected in the construction drawing. Therefore, after the completion of the buried construction work, the construction drawings will be used while using the buried construction plan drawing as it is for the part where the actual work has been performed according to the buried construction plan drawing without recreating the construction drawing from scratch. It is possible to create construction drawings efficiently. In addition, since the construction drawing can be created by correcting the buried construction plan drawing, the difference between the buried construction actual work and the buried construction plan is clear, and the construction drawing can be created accurately. Accordingly, it becomes easy to create a construction drawing in parallel with the buried construction work, and the construction drawing can be obtained quickly and accurately. In addition, by referring to the above-described construction drawings in order to create a restoration work plan drawing, it is possible to quickly create an appropriate restoration work plan drawing based on the actual work of the buried work.

  The construction drawing creation means is also realized by the computer executing a predetermined program, and reads the embedded construction plan drawing stored in the construction drawing database and displays it on the screen while following the input command by the drafter. , Configured to draw on the screen display. The construction drawings obtained in this way may be created so that the restoration work plan drawing can be obtained by overwriting the buried work plan drawing data, or added as a different layer to the construction drawing data. It may be created so that it can be obtained in a completed state, or it may be created so that a restoration work plan drawing is obtained as another data in a state associated with the construction drawing.

  Moreover, it is preferable that the said restoration construction plan drawing creation means displays the difference between the said buried construction plan and the said buried construction actual work so that identification is possible.

  If a restoration work plan drawing is created based on the construction drawing created by the construction drawing creation means described above, a restoration work plan based on the actual work of the buried work will be drafted. However, since this restoration work plan has been revised based on the actual work of the buried work, it may include a restoration work that was not planned at the time of the buried work plan. Then, the accumulated result is different from the restoration work scheduled at the time of the buried object construction plan, and there are cases where consultations and applications related to unscheduled permits and approvals occur. Then, the creator of the restoration work plan drawing creates the restoration work plan that is not scheduled at the time of the buried work plan and performs the newly increasing work most efficiently. It is necessary to understand the difference between the actual work and the buried work. Therefore, when the restoration work plan drawing creation means displays the difference in an identifiable manner by highlighting or the like, the creator of the restoration work plan drawing easily refers to the display of the difference and easily calculates the accumulated result. It is possible to grasp differences and newly generated consultations, applications, etc., and to help develop a recovery plan that allows efficient work.

  Such a display can be realized, for example, by inputting the actual work of the embedded work in an identifiable manner when inputting the actual work of the embedded work. The data corrected by is created in a separate layer from the buried construction plan drawing, and the corrected portion is displayed in a different display method, or created as another data in a state associated with the buried construction plan drawing, It can also be realized by displaying the corrected portion by a different display method and displaying it in a superimposed manner by a program.

  In addition, the restoration work support system includes an approval receiving unit that accepts approval and non-approval input of the restoration work plan drawing, accepts an input of approval to the approval receiving unit, and recovers based on the restoration work plan drawing It is preferable to provide a recovery work instruction means for instructing the work.

  The restoration work plan drawing is usually presented to the government and each person concerned with each construction company, approved after consultation application, and used for a restoration work order. Therefore, if the approval receiving unit is provided, if the restoration work plan drawing is not approved, the restoration work command is suspended and it can be determined that approval is required, and the approval is made. If so, a restoration work order is issued immediately, so that the business procedure can be performed quickly and reliably.

  The restoration work support system preferably stores attribute information related to the buried object in association with the buried object on the construction drawing.

  On the restoration work plan drawing, the type and quantity of the buried object used for the restoration work can be known, and the information can be used to grasp the budget for the restoration work from the information. At this time, the integration can be performed by referring to the attribute information of the buried object such as the unit price of the buried object, the source, and the number of days of procurement. Therefore, if attribute information is stored in association with the buried object on the construction drawing, it is possible to reduce the labor required for organizing and summarizing information for each element of the buried object.

  In addition, when the worker inputs necessary attribute information such as the type of the buried object and such association is made, the above-described tabulation work can be calculated simply by obtaining the sum, It is possible to set so that the integration work is performed.

  Furthermore, it is preferable that the additional information of the actual construction work for the buried object is stored in association with the construction target location on the construction drawing.

  In other words, in the actual work of buried construction work, photo information that shows what the work environment was, photo information that shows what the accuracy of work actually performed, etc. If additional information such as document information indicating what kind of approval was made in relation to the construction target location on the construction drawing is stored, referencing the additional information during construction work The work can be continued and the state of the buried work target location at the completion of the buried work can be easily grasped without going to the site. Therefore, when the government approves the restoration work plan drawing, the inspection items necessary for each restoration work site can be easily referred to. You can

  As a result, formal consultations and application work can be performed without going to the site to be restored.

  Hereinafter, an embodiment of the restoration work support system of the present invention will be described with reference to the drawings, taking as an example the construction of laying a gas pipe as an embedded object in the ground.

  As shown in FIG. 1, the restoration work support system displays the construction drawing stored in the storage unit, the construction plan drawing creation means 3, the construction drawing creation means 4, and the restoration construction plan drawing creation means. 5 and an output means 6 for outputting the buried construction plan drawing, the construction drawing, and the restoration construction plan drawing to an external terminal. The storage unit 2 includes a drawing database 21, a material information database 22, and an additional information database 23.

  The buried construction plan drawing creation means 3 creates a buried construction plan drawing for performing a buried construction work based on a drawing such as a topographic map, and accepts approval of the buried construction plan drawing and non-approval input. An embedded work command means 71 is provided for receiving an approval input to the unit 7 and commanding the buried work.

  The construction drawing creation means 4 creates a construction drawing by correcting the stored construction plan drawing stored based on the actual construction work.

<3> Consultation application for buried construction,
<4> Actual work of buried work,
<5> Inspection of buried construction work,
<6> Recovery work plan,
<7> Accumulation, ordering of restoration work,
<8> Application for consultation on restoration work,
<9> Actual work of restoration work <10> The work is completed according to the procedure of acceptance inspection of the restoration work. This will be described in accordance with the work procedure below.

<1> The construction work for buried objects is carried out according to the procedures shown in FIGS.
<1-1> The burial work plan drawing creator of the buried work management company is a terrain drawing describing information on roads, houses, etc., and a foundation describing basic information such as existing gas pipes and other buried objects. Referring to the information drawing etc., draft the gas pipe route to be buried. These pieces of information are stored in the drawing database 21 in the storage unit 2 and are configured to be searchable based on information such as lot numbers via the communication network 1. For example, an operator downloads a topographical drawing, a base information drawing, etc. stored in the drawing database 21 from a computer terminal via the communication network 1 (see FIG. 10), and creates a buried construction plan drawing from the computer terminal. By executing a CAD program for functioning as the means 3, it is displayed on the display unit. Then, the route can be overlaid on the displayed topographical drawing, base information drawing, and the like. At this time, the CAD program displays the topographical drawing, the base information drawing, etc. as the first layer, and creates the route on the second layer while displaying the route on the second layer (see FIG. 11). ). The computer terminal includes an arithmetic processing unit such as a CPU for starting and executing various programs, an input unit such as a keyboard and a mouse, a display unit such as a display monitor, a communication unit connected to the communication network 1, and the like. A general-purpose computer capable of installing and starting a program to be installed can be applied.

<1-2> Based on the above route, the surveyor conducts field surveys on the construction target area, checks whether the proposed route matches the actual topography, etc. Accurately measure the required distance information. Such surveying can be automatically performed by using positioning means such as GPS and inputting longitude and latitude information.
The buried construction plan drawing creator who has received such surveying corrects the above-mentioned route based on the actual measurement and uses the gas pipe type (straight pipe, branch pipe, bent) used as the buried object laid along the route. Select materials such as pipe shape types, resin pipes, copper pipes, etc.), shut-off valves, pressure regulating valves, etc.

<1-3> The selected material or the like is selected from the material information database 22 in the storage unit 2, and the attribute information of the material is recorded in association with the material information database 22 as a label. The obtained drawings are labeled with the construction area name, planned construction period, etc. as labels, and are stored in the storage unit 2 as the buried construction plan drawings in the drawing database 21 separately from the topographical drawings and base information drawings. And output to the output means 6. In addition, the created buried construction plan drawing is stored separately from the topographic drawing, the base information drawing, etc., and the topographic drawing as a separate layer is overwritten on the topographic drawing, the base information drawing. Alternatively, it may be stored together with the base information drawing.

<2> Accumulation and ordering for construction work are performed according to the procedures shown in FIGS.
<2-1> Since the obtained buried construction plan drawing is a record of the attribute information of the material used for the buried construction, the attribute information is read and aggregated by causing the computer to execute the integration program, It is possible to automatically accumulate by referring to the associated material information database 22.
Specifically, the integration program reads, for example, the attribute information such as the type of material as an embedded object (-PE pipe model number made by the company-order supplier-commercial company), counts the quantity, and the corresponding material from the material information database 22 The cost of the material is totaled for each type with reference to the unit price. The total cost is calculated for all materials listed in the buried construction plan drawing. The integration result is output to the external terminal separately from the buried construction plan drawing by the output means 6 (see FIG. 12).

<2-2> Bidding work is performed by presenting the output construction plan drawing and the accumulated result to the construction company. When a construction company is selected by bidding, when the construction company executes a predetermined program, its own computer terminal can be accessed as the construction drawing creation means 4 to the drawing database 21, and the construction can be started.

<3> Consultation application regarding buried construction work is made in accordance with the procedures in FIGS.
<3-1> Based on the buried construction plan drawing, the selected construction company discusses with the government, other construction personnel, construction area surrounding personnel, etc., and performs a procedure such as application for approval. When the construction plan needs to be changed, the buried construction plan drawing is changed each time.
<3-2> Approval of the approval application from the administration is received by the approval receiving unit 7 via the communication network 1 (see FIG. 13). In the figure, the approval is performed by checking a check box, and various commands are issued according to the status of the check. When there is an unapproved item, the process of <3-1> is repeated. Further, when all the inputs for approval are obtained, the buried construction work instruction means 71 instructs the buried construction work, and the actual work of the buried construction can be advanced.

<4> The actual construction work for buried objects is performed in accordance with the procedures shown in FIGS.
<4-1> Dig up the construction area. At this time, if there is an error or deviation in the existing base information, or if the construction environment is significantly different from the preliminary survey, the construction work will proceed while correcting the buried construction work plan. When the buried construction worker modifies the buried construction plan, the construction drawing creation means 4 is used to modify the buried construction plan drawing.

  Specifically, the embedded construction plan drawing stored in the drawing database 21 is downloaded from the computer terminal via the communication network 1, and a CAD program for causing the computer terminal to function as the construction drawing creation means 4 is executed. Thus, the buried construction plan drawing can be displayed and corrected. The correction input is created in a state where it is displayed on the screen displaying the buried construction plan drawing, and the construction drawing is created as a different layer added to the buried construction plan drawing and can be displayed in an identifiable manner. (See FIG. 14).

<4-2> The buried construction worker creates additional information such as a photograph of the actual progress of the buried construction work and approval approval documents. The additional information is stored in the additional information database 23 in the storage unit 2 provided on the communication network 1, and is associated with the construction target location on the construction drawing and can access the construction drawing, the construction company, It is stored so that it can be referred to by the administrative / construction personnel.
