Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a storage cell having improved storage capacity,

The present invention relates to a storage cell and its connection structure which are easy to store, move, and construct by reducing its own weight, and in particular, to improve structural capacity while improving storage capacity.

In general, due to the increase of buildings or the increase of the packing rate of the surface, rainwater is flown into the sewer or river at a time without flooding to the underground at the time of heavy rainfall, and flooding may occur as a result of exceeding the inflow limit.

On the other hand, if the inflow of the river is small, the water quality deteriorates and the groundwater becomes depleted. For this reason, rainwater was once stored in a rainwater storage facility composed of concrete or synthetic resin placed on the spot, and a technique for controlling the flow rate to the stream was developed.

One of the techniques for solving the above problems is disclosed in Japanese Patent Laid-Open No. 6-27299.

The present invention is characterized in that a block for a block body is provided with a horizontal beam at the upper end portion of four corner pillars of the bottom face plate portion and an upper face opening is formed between front and rear horizontal pillars and left and right horizontal pillars, Shaped peripheral block portion provided with a sleeve wall portion connecting the upper plate portion and the end portion of the bottom plate and a bottom plate portion connected to the lower end portion of the side plate portion and connecting the upper plate portion to the upper portion, The side opening of the block group for the main body is closed by the peripheral block, and the top opening of the block for the main body is closed by the cover plate mounted on the horizontal beam.

However, such a rainwater storage tank is advantageous in that the weight of each block is lightened, so that it can be easily transported and handled. However, since each part is separated, a lot of labor and assembly time are required for assembling each part, Is increased.

Korean Patent Registration No. 485742 discloses a structure in which pillars are erected at right angles at four corners of the top plate and the bottom plate at right angles, openings are formed at four sides by the pillars, And a plurality of grooves into which a plurality of nut insertion grooves are formed on the inner side and a plurality of grooves into which the couple guide pins are respectively inserted are formed on the outer surface, And a screw member extending outwardly from the peripheral portion block to close the opening portion of the peripheral portion block facing outward when assembled, the peripheral portion block having the same configuration as that of the main body portion block, And a slab coupled to the block.

The rainwater storage tank is advantageous in that the construction cost can be reduced compared with the conventional art because the rainwater storage tank joins the blocks and the slab through the screw member. However, the blocks for the main body part and the peripheral part each include the columns, There is a disadvantage in that the columns of blocks are overlapped to provide an unnecessarily thick columnar structure.

In addition, since the rainwater storage tank generally interconnects the upper part and the lower part via one wire, when the ground is unbalanced, the construction is considerably inconvenient and the construction time is long.

In addition, since the blocks used in the rainwater storage tank are usually manufactured as a separate product to meet the construction site, it is difficult to produce standardized blocks, and in order to use blocks smaller or larger than the manufactured blocks, There is a problem that falls significantly.

In addition, the rainwater storage tank is structurally unstable because there is no reinforcement for lateral loads such as seismic loads and lateral loads such as overhead loads.

In addition, the rainwater storage tank has a problem of concrete deterioration due to the accumulation of rainwater directly on the material of the concrete.

On the other hand, in FIG. 4, one of the storage cells 1 is constituted by a filtration module, and the filtration is performed in the storage cell 1 in which contaminants are selected from the stored rainwater, So that the rainwater storage tank itself can be subjected to boiling treatment.

That is, as shown in FIG. 4, the longitudinal connection plate 3-1 is mounted on the upper surface of the storage cell 1 in the drawing, while the filtration longitudinal connection plate 3-3 is mounted on the lower surface of the storage cell 1, And the filtration transverse direction connecting plate 4-2 is mounted on the flow paths 28 and 29.

That is, the rainwater flowing into the inner storage space 21 through the longitudinal connection plate 3-1 is stored, and the rainwater filtered by the filtration longitudinal connection plate 3-3 is filtered in the longitudinal direction. And the rainwater filtered in the forward direction by the filtration lateral connection plate 4-2 in the transverse direction flows into the adjacent storage cell 21 adjacent to the storage cell 1 (Flow paths 28 and 29) of the inner storage space 1 of the first embodiment. The storage cell 1 thus selected is constituted by a filtration module, and the rainwater, which has passed through the selected storage cell 1 and has been subjected to the boiling point, flows and stored in the other storage cell 1, And the rainwater storage tank itself can be boil-off processing.

The storage cell 1 selected as the filtration module in this way is preferably located at the uppermost position and positioned at the initial entrance where the rainwater flows into the rainwater storage tank. In the embodiment shown in FIG. 4, only the rainwater stored in the inner storage space 21 is treated to have a boiling point. When the whole is filtered, the smooth flow of the fluid may be restricted, Only the inner storage space 21 in which a larger amount of rainwater flows and stored is filtrated and the rainwater flows and stored in the outer storage space 22 without filtration.

Although not shown in the drawing, the finishing material can be further processed on the outside of the rainwater storage tank formed by assembling the storage cells 1. The finishing material surrounds the outside of the rainwater storage tank, and the rainwater stored in the rainwater storage tank is leached out A water-permeable sheet can be used. The permeable sheet is made of a nonwoven fabric or the like, and it is preferable to adjust the particle diameter of the nonwoven fabric according to the classification of the ground in order to prevent clogging.

Here, the occlusion phenomenon refers to a phenomenon in which the soil particles are separated from the soil matrix and then moved by the flow of the fluid in the gap of the nonwoven fabric, thereby filling up the gap of the nonwoven fabric. This reduces the watertightness of the nonwoven fabric, It is proper to use the nonwoven fabric by controlling the particle size of the nonwoven fabric according to the classification of the ground in order to prevent it from being leached into the ground.

The permeable sheet made of the nonwoven fabric or the like functions not only to allow the rainwater stored in the rainwater storage tank to be leached into the ground but also to prevent the foreign matter from flowing into the rainwater storage vessel from the outside.

On the other hand, the finishing material may be a car shape sheet which prevents the rainwater stored in the rainwater storage tank from leaking out. The car shape sheet may be made of EDPM material or the like and functions to prevent the infiltration of groundwater of the rainwater stored in the rainwater storage tank and the inflow of foreign matter into the rainwater storage tank. In case of using the car water- It is desirable to provide a separate drain pipe or the like for the external leakage of the rainwater stored in the rainwater storage tank.

As described above, the permeable sheet is installed outside the rainwater storage tank according to the finishing material so that the rainwater can be leached into the ground (hereinafter referred to as the infiltration type), and the leaching of the rainwater into the ground is blocked, In order to use the stored rainwater for other purposes, the outside of the rainwater storage tank may be wrapped with a car shape sheet so that rainwater can be stored in the rainwater storage tank (hereinafter referred to as a car shape) It is preferable to further provide a water permeable sheet for protection to the inside and outside of the car shape sheet because the car shape sheet may be damaged by the pressure of rainwater because there is no leakage to the outside. Further, the infiltration type and the differential type can be used together (hereinafter referred to as a combination type).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
