After flattening the surface, laying gravel, then pouring fresh concrete, finally making the foundation. And on top of this, masonry retaining wall, gravity type retaining wall, semi-gravity type retaining wall, leaning retaining wall, cantilever type retaining wall, retaining wall type retaining wall, supporting wall type retaining wall or box type retaining wall etc. After setting up, you can pull out the sheet pile and demount it, or you can make the foundation in the same way as above and assemble a formwork on this so that a concrete retaining wall with a certain thickness can be constructed A common method is to set the ground, let it cure for a certain period of time, remove the formwork, pull out the sheet pile, and then level the ground.

Although a lot of labor is spent on pulling out the sheet pile and demounting it, all of these works are on-site work, which is a heavy labor. On the other hand, the latter construction method is the same as the former construction method, where the foundation work is carried out by on-site work.Furthermore, on this, a framework for making retaining soil retaining walls and placing of concrete are placed, followed by dismantling of this formwork and sheet pile. Since it is necessary to perform work such as pulling out and leveling the ground, that is, all the work of this construction method on site, the number of man-hours is very large and it is heavy labor. In addition, these construction methods also have a problem that a certain curing time is required after that in order to place the fresh concrete in the foundation construction and the soil retaining wall construction of the latter method, and the construction period is long. . Furthermore, in the above-mentioned construction methods, particularly when constructing on soft ground, it is necessary to excavate very deeply to form a foundation, which requires an extremely large number of man-hours. In addition, when these construction methods are applied to the seawall, the foundation will be inclined due to the erosion of the ground by water, and the earth retaining wall will also be inclined or, in the worst case, it will fall.

Specifically, the piles are driven in the soil at appropriate intervals, and the piles are placed at both ends between them. It has a hole to enter and it is connected by a precast concrete block that is notched so that it can be joined with an adjacent precast concrete block, and by stacking it on top of this, it is hard work, and the on-site work is extremely reduced. As a result, man-hours have been greatly reduced. In addition, the curing period after placing the concrete, which requires a long period of time as in the past, has been eliminated, and the construction period can be greatly shortened.

斜したり、転倒したりすることは全くない。As described above, according to the soil retaining wall construction method of the present invention, since piles and precast concrete blocks mass-produced at the factory may be transported to the site at the time of construction and assembled prior to construction, the number of man-hours and the construction period can be reduced. It was very helpful in shortening. Further, since the pile retaining work and the precast concrete block arranging work can be carried out by a large-sized machine in the soil retaining wall construction method of the present invention, almost no manpower is required and therefore the work can be performed easily. Furthermore, since the piles are driven deep in the construction method of the present invention, a strong soil retaining wall can be formed even on soft ground, and therefore when the revetment embankment is formed by the construction method of the present invention, this is inclined due to water erosion, There is no fall.

FIG. 3 is a front view of the precast concrete block of FIG. FIG. 4 is a plan view of an embodiment of the present invention in which a precast concrete block is arranged on a pile driven into the soil at regular intervals. FIG. 5 is a front view in which a precast concrete block is arranged on the pile of FIG. First, a precast concrete pile (1), a hole (3) into which the pile is inserted in the longitudinal direction at both ends, and a notch (4) for connecting to a precast concrete block adjacent to the upper part of both ends. Block (2) was produced at the factory and transported by truck to the construction site. Next, the piles were erected vertically on the ground at intervals of 5 m and driven straight into the soil. Furthermore, the ground between these piles is shallow enough to accommodate the precast concrete block (2) and horizontally excavated, then into two piles (1),
The holes (3) at both ends of the precast concrete block (2) were inserted. At this time, the precast concrete block had notches (4) at both upper ends, and the back surface of the precast concrete block had a cantilever. Furthermore, after arranging the precast concrete blocks (2) of the same shape as the above in the same direction and arranging them every other row side by side, every other row in the first row has a cantilever beam. An unprecast concrete block (2) was sequentially arranged in the horizontal direction with the vertical direction reversed from the above, and the first row was completed. Subsequently, the precast concrete blocks in the second and third rows were arranged in the same manner as above to complete the earth retaining wall. All of the above soil retaining walls could be made with a large machine, and there was little manpower. The construction method of the present invention described above is particularly suitable for forming a retaining wall for soil retaining on soft ground and for use as a seawall. In the present invention, piles, H steel, composite steel pipe piles, etc. can be preferably used as the piles, and as the precast concrete blocks, those having a shape that can be spliced in the horizontal direction and can be piled up in the vertical direction can be used. It is possible.

ある。As described above, according to the present invention, the soil retaining wall is produced by a large-sized machine using the piles and precast concrete blocks that are prefabricated before the construction work. Since the number has been reduced to a great extent, it has been possible to save a lot of labor, and the risk of human accidents has been reduced. This helps improve the work environment at the construction site, which is often shunned as a 3K workplace.
