Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction method for a retaining wall or earth retaining body having a support body.

The form of the retaining wall or earth retaining body of this invention uses the well or caisson method, and the entire structure of the desired retaining wall or earth retaining body is not simultaneously constructed integrally, but is basically constructed using a small partial construction method. It is a construction method that connects and integrates similar small-sized component parts, and the purpose is to construct a supporting body that can receive pressure from both at the joint.

This is because the topographical conditions at the location where a retaining wall or earth retaining body of the desired shape is to be constructed simultaneously are special, and the impact associated with its creation is significant. The main purpose is to perform this on a small block basis in a very small area, and to connect and connect the blocks to be constructed using support bodies.

Next, one embodiment of the present invention will be described with reference to the drawings.
The figure is a plan view showing the construction site, where 1 is the main structure and 2 is the supporting body.

These structural main body 1 and supporting body 2 are relatively small wells,
Alternatively, a relatively small structure constructed using the caisson method may be constructed on-site, and if environmental conditions permit, a structure constructed elsewhere may be brought in and constructed. The structural main body 1 of In addition, the support body 2 has a structure that can naturally carry the purpose of the support body to carry the load borne by the two structural bodies 1, and there are is to provide a working space 4, and a retaining wall or earth retaining body I
At the location where the two structural bodies 1 are to be constructed, construct or install the support body 2 with the inner surface at the position where the opposite surface can join the surface on which the earth pressure is applied at the position where the respective ends of the two structural bodies 1 are connected, and After that, as mentioned above, for one dependent 2, 2
It is constructed or installed in such a way that one end of each of the structural bodies 1 can be joined, and the three bodies are sunk so that they come together, but as a general rule, the supporting body 2 is placed first. The structure is first submerged, and then the two structural bodies 1 are constructed simultaneously or individually. Also, depending on the construction environment, these three bodies may be constructed at the same time. In any case, it is important to construct the structure so that the inside of the support body 2 can be brought into close contact with the outside of the opposite side that receives the earth pressure on the outside of the joint where the two structural bodies 1 are parallel to each other. . The above-mentioned construction work for constructing the main body 2 is performed by excavating and depositing the work spaces 3 and 4 in the same way as the general well or caisson construction method, but uneven settlement or the construction work is difficult. In such a case, a rod 6 connected to an anchor 5 anchored to stable ground underground at the same location is projected above the ground, a pressure receiving material 7 is tied to this, and the lower surface of the pressure receiving material 7 and the above-mentioned submerged body are connected. A hydraulic jack 8 is installed between the upper surfaces of a certain structural body 1 and a dependent body 2.
is inserted and activated, the pull-out resistance of the anchor 5 is utilized, and the reaction force is used to assist the sinking of the submerged object or correct the uneven sinking described above.

This invention is intended to be constructed as described above, and consists of at least two relatively small structural bodies 1 and one supporting body 2 in a place where a long retaining wall or earth retaining body is required. - By configuring the construction so that work can be carried out block by block or by a small number of blocks, the purpose is to prevent collapse in areas where construction is to be carried out, mainly mountain slopes, slopes, slopes, etc. that are prone to collapse. Since it is a construction project, the greatest fear is that it will damage the environment of the area, and by doing this on a small scale and in succession, it is possible to bring the area closer to its natural state with even less effort. It is effective in that it can be carried out quickly and there is no risk of disadvantages such as collapse during construction work for the purpose of collapse prevention.

Claims (1)

[Claims] 1. At the location where a retaining wall or earth retaining body is required, these three structures consisting of two relatively small structural bodies 1 each having a working space 3 and a support body 2 having a working space 4 are made into one block,
At least one block is regarded as one work unit, and the support body 2 is sunk by excavation work in the work space 4, and this one support body 2 is
The respective ends of the two structural bodies 1 are joined inside the body and sunk to the desired position, and the structural bodies 1, 1 and the supporting body 2 are integrated, and they are shaped to the desired length. A support structure constructed in a continuous manner until the structural main body 1 and the support body 2 are connected to each other, so that the earth pressure received from the surface opposite to the surface joined to the support structure 2 can be received by the structural main body 1 and the support structure 2.
