Description

[Detailed Description of the Invention] The present invention relates to a retaining wall for retaining earth at road construction sites in mountainous areas.

Conventionally, retaining walls for retaining earth are made by combining long concrete horizontal members and short vertical members in a grid pattern vertically and horizontally to form a frame frame.The frame frame is filled with stones and the upper and lower long horizontal members are In this case, each column is made of concrete, so dimensional errors are likely to occur, resulting in differences in the gaps between the long cross members, and the pillars themselves are also different. Since it is difficult to mold the bottom to a constant size, it has been impossible to tightly fit the pillow material between the long cross members.

In addition, this type of column material is intended to prevent cracking of the long cross members simply due to the load from above, and is designed to prevent the long cross members from shifting in their longitudinal direction due to the internal pressure of stones, etc. It was not possible to prevent a gap from forming at the abutting part, and as a result, there was a risk that the short vertical members installed at the abutting part would come off and the entire retaining wall would collapse.

In view of these points, the present invention has been designed to ensure that the top surface of the column is accurately aligned with the bottom surface of the upper cross member even if an error occurs in the thickness of the short vertical member and the gap between the upper and lower long cross members is assumed to be the specified size. The aim is to build a strong retaining wall by keeping the horizontal members in close contact with each other to prevent damage to the horizontal members and their displacement in the horizontal direction.One example of this is explained based on a drawing. 2 is a short vertical member made of concrete; a is a frame formed by combining long horizontal members 1 and short vertical members 2 vertically and horizontally in a cross-shaped configuration; 3;
Reference numeral 3 designates a concrete model pillow material that fits in the gap 4 of the upper and lower elongated cross members 1, 1 in opposite directions, and there are projecting edges 5 that fit on the outside of the upper cross member 1 at the front and back of the upper surface. , 5 are provided.

6, 6 are a pair of left and right slanted boxes which are shaped so as to be inclined outward as they reach each other's ends at a distance from each other on the lower surface of the upper elongated horizontal material 1; 7, 7 are pillow materials 3; This is an inclined surface that is shaped on the upper surface of 3 and brought into close contact with the inclined boxes 6, 6.

Further, reference numeral 8 is a stone filled in the frame a, 9 is a foundation member, and 10 is a butt portion of the elongated horizontal member 1.

One embodiment of the present invention has the above-mentioned configuration, so the long cross members 1, 1 are arranged continuously in the longitudinal direction on the front and rear of the foundation member 9, and then the long cross members 1 are placed on the front and rear of the base member 9. The short vertical members 2 are erected at intervals, and then the cross members 1 and the vertical members 2 are stacked alternately in a grid pattern to form a frame frame a, and the gaps 4 between the upper and lower cross members 1 are filled with pillow materials 3. 3 loosely fit together, and the inclined surface 7 on the upper surface thereof
, 7 to match the inclined boxes 6, 6 of the upper elongated horizontal member 1, and then fill the framework a with stones 8 to construct a strong retaining wall.

In the above embodiment, the inclined box 6,
6 is provided, however, inclined text surfaces 6, 6 may be provided on the upper surface of the elongated cross member 1.

As described above, the retaining wall for earth retaining according to the present invention has a pair of left and right sloped faces formed on the long horizontal members of the conventional retaining wall for earth retaining, and this sloped face fits into the gap between the upper and lower horizontal members. Since the sloped surface of the pillar material of the model was inserted, even if the gap between the upper and lower horizontal members is different due to an error in the thickness during the molding of the short vertical member or distortion of the long horizontal member, the pillar material will be By driving into the inclined protruding surface portion, the upper cross member is reliably supported by the lower cross member, thereby making it possible to prevent damage to the cross member due to loads from above.

In addition, since the pair of left and right sloped faces are formed so as to slope outward as they reach the ends of the cross members, the internal pressure of the stones, etc. filled in the frame causes the frame to bulge, causing the cross members to swell. There is no possibility that the retaining wall will slip and create a landlock at the abutting portion, and therefore a robust retaining wall for retaining earth can be constructed.
