Description

Temporary Structure For Land-Side Protection Wall}

The present invention relates to a temporary construction structure for the earthquake used to excavate the ground, and more specifically, to build a reinforcement beam side by side on the back of the strip to support the back of the strip stably without the use of a brace to support the ground by earth pressure This can effectively prevent the collapse, as well as to improve the construction excavation structure for the earthquake structure to secure a wide space for excavation of the building to facilitate the construction of the building.

In general, construction works such as buildings, cut-off tunnels, subways, power outlets, communication ports, sewage conduits, etc. extend and excavate the ground in a predetermined depth and length direction, and install a structure in the internal space of the excavated ground. have.

In such a case, the excavated ground surface always tries to collapse by earth pressure (driven earth pressure). Therefore, as shown in FIG. 1, a vertical beam 210 such as an H pile is first driven and buried in the ground, and then the ground is ground. Excavation ground support is installed by inserting the earth wall 220, earth plate, usually using timber.

At this time, the vertical beam 210 having the earth wall 220 is installed to install a horizontal beam-shaped band (230, Wale, H file), which is vertical by connecting the vertical beam 210 in a horizontal direction to each other This is for the beam 210 and the band length 230 to more effectively resist the main earth pressure applied to the lattice structure. Further, between the strip 230 and the strip 230 is installed both ends across the excavation ground to support the strip (230) so that it is also able to resist the earth pressure, but also to support the struts 240, Strut is also H file This is commonly used.

Since the support 240 is installed as a kind of lateral support beams between the bands 230 installed on the ground excavation surface to effectively resist the working earth pressure, it is used for almost all excavation ground support.

However, conventional excavated ground supporters have their advantages, but the greater the excavation depth, the greater the magnitude of the earth pressure acting, so that the number of installations of the support beams increases according to the excavation depth and the installation interval (mostly 2-3M) decreases. It is a serious obstacle in the use of the excavation space, especially when it is necessary to move the position of the brace already installed during the work takes a lot of effort and time. Therefore, in the related art, there is a great need for development of construction technology that minimizes the number of installation of the braces or does not require the installation of braces at all.

In view of this, as shown in FIG. 2, a prestressed strip consisting of a horizontal triangular pedestal 351, a triangular fixing device 352, and a connection pedestal 353 and a tension member 354 connecting them are prestressed. Wale) 350 and the provisional facility (Korean Utility Model Registration No. 20-322945 (IPS construction method)) is composed of a support 360 to support the triangular fixing unit 352 at the corner portion.

In this structure, the tension member 354 is disposed in a parabolic form on a horizontal triangular pedestal 351, and both ends thereof are tensioned by a triangular fixing device 352 supported by an edge brace 360. After being fixed, it can be seen that each end is bent and installed through the side stand of the triangular pedestal 351 as shown in the excerpt perspective view.

This is because the prestressed belt length 350 is horizontally installed on the ground excavation surface, so when the tension member 354 is tensioned and settled as it is, the prestressed belt length 350 may not be supported differently and may fall. . Accordingly, the triangular pedestal 351 of the horizontal type is first supported by the edge brace 360 of the excavation ground, and the end of the tension member is passed through the side pedestal constituting the triangular pedestal 351. It can be seen that the end of the tension member is bent in order to secure a space for fixing the tension member so as not to be interfered by the triangular pedestal 351.

However, in order to install the prestressed belt, it is necessary to install the corner brace 360 or the corresponding member in the end, and thus, there is a problem in that the space benefit of removing unnecessary braces is eliminated. Furthermore, in the case of the tension member as a whole is arranged in a parabolic form, such a parabolic shape can not only be adjusted by the height of the installation of the horizontal triangular pedestal 351 supporting the tension member, the structural structure that can not easily adjust the tension angle of the tension member The problem was noted.

That is, since the tension re-installation angle has a great influence on the size of the horizontal compression prestress introduced into the tension member, if the installation angle adjustment is not easy, there is a problem that the field applicability of the pre-stress band is very poor.

The present invention is to solve the conventional problems as described above, the purpose is to stably support the back of the belt without using a brace to effectively prevent the ground collapse by earth pressure, as well as excavating buildings It is to provide a temporary structure for the earthquake block structure to make the construction of the building convenient by securing a wide space.

In another aspect, the present invention is structurally stable without installing a tension member on the back of the strip, and effectively prevents the ground from being collapsed by earth pressure, and provides an improved temporary structure for the earthquake structure to facilitate the design and construction of the structure.
