Summary of the Invention

Problems to be Solved by the Invention

[0004] As such an embankment structure, in addition to arranging a plurality of members extending vertically and disposing a plate-like member between these members to form a wall, a wall is also formed by arranging a plurality of members extending vertically adjacent to each other. In the latter case, there is a concern that the embankment material may reach the other side of the front and back of the wall and leak through the gaps between adjacent members. This is because, if adjacent members are not arranged close enough to each other, or if one axis of an adjacent member is inclined with respect to the other axis, a region with a large gap is partially formed.

[0005] The present disclosure has been made to solve such problems, and an object thereof is to be able to form an embankment structure while preventing the embankment material from leaking, regardless of the arrangement status of the members and the type of embankment material.

Means for Solving the Problems

[0006] The method for manufacturing an embankment structure according to this disclosure comprises a partitioning procedure for dividing the ground surface and the space above the ground surface in the front-back direction of the wall by arranging a plurality of vertically extending members horizontally to form a wall; a layer forming procedure for forming a resin layer that extends along either the front or back surface of the wall; and an embankment procedure for filling the space on either the front or back side of the wall with embankment material. [Effects of the Invention]

[0007] According to this disclosure, since a resin layer is formed along either the front or back surface of the wall, it is possible to effectively prevent the embankment material from reaching and leaking to the other side of the wall. This is because even if there are areas with large gaps due to adjacent members not being placed close enough to each other, or one axis of adjacent members being tilted relative to the other axis, the resin layer is formed to seal such gaps.

[0009] Hereinafter, one embodiment of this disclosure will be described with reference to the drawings. (1) Overall structure

[0010] As shown in Figures 1 and 2, the embankment structure 1 comprises a wall body 10 formed by arranging multiple vertically extending members horizontally, a resin layer 20 extending along either the front or back surface of the wall body 10, and embankment material 30 filled in the space on either the front or back surface of the wall body 10. In this embodiment, an example is given of manufacturing the embankment structure 1 on a downward sloping slope as the ground surface 100.

[0011] The wall structure 10 consists of cylindrical columnar members 11 arranged in a direction intersecting the slope direction of the embankment, thereby dividing the ground surface 100 and the space above the ground surface 100 in the front-back direction. In this wall structure 10, the lower end of each columnar member 11 is embedded in the ground. In this embodiment, steel pipe piles are used as the columnar members 11.

[0012] The resin layer 20 is a foamed resin layer made of foamed resin.

[0013] (2) Method of manufacturing the embankment structure 1 The method for manufacturing the embankment structure 1 described above is explained below.

[0014] In this embodiment, a partitioning procedure is performed first. In this partitioning procedure, as shown in Figure 3(a), a wall body 10 is formed by arranging a plurality of columnar members 11 side by side, thereby partitioning the ground surface 100 and the space above the ground surface 100 in the front-back direction of the wall body 10 (left-right direction in the figure). Here, the plurality of columnar members 11 are arranged adjacent to each other in a direction that intersects with the slope direction of the embankment (front-back direction of the paper in the figure), and the lower end of each member is embedded.

[0015] Next, a layer formation procedure is carried out. In this layer formation procedure, as shown in Figure 3(b), a resin layer 20 is formed that extends along either the front or back surface of the wall 10. Here, the resin layer 20 is formed along the surface located on the lower side of the slope of the wall 10. At this time, the resin layer 20 is formed by hardening the foamed resin sprayed onto the wall 10.

[0016] Then, the embankment construction procedure is carried out. In this embankment construction procedure, as shown in Fig. 3(c), embankment is carried out by filling the space on either the front or back surface side of the wall body 10 with embankment material 30. In the present embodiment, among the front and back surfaces of the wall body 10, the embankment material 30 is filled into the space on the surface side located on the upper side of the slope surface.

[0017] (3) Variations As described above, the embodiments of the present disclosure have been explained. However, the present disclosure is not limited to the above embodiments, and various modifications are possible without departing from the gist of the invention. In particular, the plurality of modifications described in this specification can be arbitrarily combined as needed.

[0018] For example, in the above embodiment, the case of manufacturing the embankment structure 1 on the slope surface which is the ground surface 100 has been illustrated. However, it is needless to say that the embankment structure 1 can also be manufactured on the ground surface 100 other than the slope surface.

[0019] Also, in the above embodiment, after manufacturing the embankment structure 1, the resin layer 20 may be removed, or it may be left as it is. When leaving the resin layer 20, a configuration in which a protection panel is further provided on the surface of the resin layer 20 may be adopted.

[0020] Also, in the above embodiment, the case where the wall body 10 is constituted by the columnar member 11 having a cylindrical shape has been illustrated. However, the wall body 10 may be constituted by a member other than a cylindrical shape.

[0021] Also, in the above embodiment, the configuration in which the resin layer 20 is formed by curing the foamed resin sprayed on the wall body 10 has been illustrated. However, the resin layer 20 may be formed by arranging a sheet made of foamed resin.

[0022] Also, in the above embodiment, the configuration in which the resin layer 20 is formed on the surface of the wall body 10 located on the lower side of the slope surface has been illustrated. However, the resin layer 20 may be formed on the surface of the wall body 10 located on the upper side of the slope surface.

[0023] (4) Operational effects According to this embodiment, since a resin layer 20 is formed that extends along the wall 10, it is possible to effectively prevent the embankment material 30 from reaching the other side of the wall 10 and leaking out. This is because even if there are areas with large gaps in some parts, such as when adjacent columnar members 11 are not placed close enough to each other, or when one axis of an adjacent columnar member 11 is tilted relative to the other axis, the resin layer 20 is formed to seal such gaps.

[0024] Furthermore, in the manufacturing method of the embankment structure 1 according to the above embodiment, leakage of the embankment material can also be prevented by forming the resin layer 20 along the surface of the wall 10 that is located on the lower side of the slope. Therefore, even if it is difficult to enter the space on the upper side of the slope to perform the work when forming the resin layer 20, it is possible to perform the work from the lower side of the slope with the wall 10 in between.

[0025] Furthermore, in the manufacturing method of the embankment structure 1 according to the above embodiment, a resin layer 20 is formed by hardening foamed resin, so as shown in Figure 4, a resin layer 20 can be formed in a shape that follows multiple columnar members 11 and the gaps between them.

[0026] Furthermore, the embankment structure 1 of the above embodiment does not unnecessarily increase the weight of the structure because, due to its structure, a lightweight resin layer 20 is formed on the wall body 10. [Explanation of Symbols]
