Abstract

PURPOSE:To make side pressure supportable efficiently in a stable manner by extending a soil improver in crossing with a load direction of the side pressure as in formation, while installing both front and rear antibodies along both front and rear side ends in the side pressure load direction of this soil improver, and connecting both these front and rear antibodies with a tensioner. CONSTITUTION:A lot of soil improving piles are driven in the reclaim area of a soil improver 11 in all directions, thereby creating this soil improver 11. Next, a mounting ditch is digged in both horizontal and vertical directions of this soil improver 11. In succession, each of both front and rear antibodies 12 and 13 is inserted into both ends of this mounting ditch. In addition, a tension member 14 is set up in a longitudinal ditch hole lying between the front antibody 12 and the rear antibody 13. When those of front and rear antibodies 12, 13 and a tension member 14 are set up, bentonite slurry is filled up in the mounting ditch, maintaining the stability of a wall surface. In addition, when setup operations of these elements are over, cement milk is poured thereinto from a bottom part of the mounting ditch, replacing it with this bentonite slurry into solidification, whereby the soil improver 11, both front and rear antibodies 12, 13 and the tension member 14 are all unified as one body.

2. Description of the Related Art For example, when strengthening a soft ground or when the ground is used as a civil engineering structure as it is, a solid and stable ground improvement body is obtained by mixing a solidifying material into the ground or freezing the ground. The consolidation method is often adopted. And when such an improved body is constructed as a retaining wall or a retaining wall for preventing the movement of the ground due to landslide when performing the excavation method, such an improved body has a small strength against the tensile force. It is necessary to design the improved body so that a large tensile stress does not occur due to the moment. That is, in order to stably support a large lateral pressure, it is necessary to form a modified body with a large modified width in the load direction of the lateral pressure.

However, when the above-mentioned ground improvement body is used as a wall body for retaining soil, construction cost of the improvement body is high, and it is uneconomical to make a large improvement width. However, there is a problem that it is difficult to form a stable earth retaining wall at a work site where the improvement width cannot be sufficiently obtained such as when an improvement body is formed adjacent to an existing structure.

Further, in the excavation method for excavating one side surface of the improved body, a method of strengthening the rigidity of the improved body by inserting a reinforcing steel material along the excavated surface is also adopted, but it is sufficient.
