BACKGROUND OF THE INVENTION
The present invention relates to a retaining wall block, a partition plate, and a retaining wall construction method using a retaining wall block and a partition plate, which are used for revetments such as rivers, coasts, and lakes, or slope walls such as roads and parks. It is about.
[0002]
[Prior art]
Conventionally, as shown in FIG. 16, a retaining wall on a riverbank or on a slope such as a road is from a concrete block for retaining walls, for example, a rectangular parallelepiped hollow block B1 whose upper and lower surfaces are open, or from the side. The parallel block-shaped hollow block B2 is formed by stacking the walls along the slope afterwards.
[0003]
In the retaining wall formed by stacking such hollow blocks B1 and B2, concrete, chestnut, and crushed stone are respectively formed in the inner space of the hollow blocks B1 and B2 and the inner space of the pair of adjacent hollow blocks B1 and B2. The hollow blocks B1 and B2 are fixed by filling the filling material W such as earth and sand (see, for example, Patent Documents 1, 2, and 3).

[Problems to be solved by the invention]
By the way, as described in Patent Documents 1 and 2, when the hollow block is fixed by filling the inner space of the hollow block with crushed stone, crushed stone, earth and sand or the like as the filling material, it is excellent in economic efficiency and environmental function. However, there is a problem that the bonding strength between the hollow blocks is inferior. On the other hand, when concrete is filled as the filling material in the inner space of the hollow block and the hollow block is fixed, the hollow block can be firmly joined to form a retaining wall, but it is economical and environmentally functional. There is a problem of being inferior.
[0006]
In other words, when chestnut, crushed stone, earth and sand, etc. are used as the filling material, the space of the filling material becomes a living habitat, and the retaining wall can be greened, whereas concrete is used as the filling material. When used, voids do not occur and the growth of animals and plants becomes extremely difficult.
[0007]
In addition, as described in Patent Document 3, while filling the inner space of each hollow block with chestnut, crushed stone, earth and sand, etc. as the filling material, the filling of the inner space of the pair of adjacent hollow blocks as the filling material It has been proposed to fill concrete and have excellent economic efficiency and environmental functions, and to form a retaining wall by firmly joining the hollow blocks, but the inner space of each hollow block is in the front-rear direction and the vertical direction. Only water can be circulated, and water in the left-right direction cannot be circulated. For this reason, depending on the amount of water flowing in the left-right direction, there may be cases where green retaining walls and non-greening retaining walls coexist, and it may not be possible to secure the habitat of living organisms. There was a drawback that it was not possible.
[0008]
The present invention has been made in view of such problems, and provides a retaining wall block that has a more excellent environmental function and can be firmly joined, and a partition used for the retaining wall block. A board is provided. In addition, the present invention provides a method for constructing a retaining wall that uses a retaining wall block and a partition plate and has a more excellent environmental function and can construct a strong retaining wall.

On the other hand, a notch 2c is formed at the center and left and right ends of the upper edge of the front wall 2, and the space S and the front wall 2 defined by the front wall 2, the rear wall 3, and the pair of side walls 4, respectively. Are communicated with an open space defined by the projecting tip, the projecting tip of the rear wall 3 and the side wall 4.
[0039]
Here, as the shape of the through hole 2a, an arbitrary shape such as a rectangle, a circle, or a long hole can be selected. Further, instead of forming the notch portions 2b at the left and right end edges of the front wall 2, or together with the notch portions 2b, through holes are formed at the left and right end portions, and the front end portion from which the front wall 2 protrudes, You may make it communicate with the open space divided by the front-end | tip part and the side wall 4 which the rear wall 3 protruded.
[0040]
In addition, when the retaining wall block 1 is piled up in the up-down direction, the notch portion 2c forms a gap at the abutting portion of the pair of retaining wall blocks 1 adjacent in the up-down direction.
[0041]
Similarly to the front wall 2, the rear wall 3 is a horizontally long rectangular plate, and is spaced in the left-right direction at a position facing the space S defined by the front wall 2, the rear wall 3, and the pair of side walls 4. A pair of recesses 3a (see FIG. 2), which are thin portions, are formed. For this reason, the recess 3a can be easily opened by knocking out with a hammer or the like. In this case, through the opening 3a ′ (see FIGS. 7 and 14) formed in the rear wall 3, the back ground, The space S defined by the front wall 2, the rear wall 3, and the pair of side walls 4 in each retaining wall block 1 can be communicated. Moreover, a nut (not shown) is embedded in the upper end on the inner surface side of the rear wall 3, and a connecting plate 7 described later can be fixed via a bolt.
[0042]
The rear wall 3 is formed to be slightly shorter than the width of the front wall 2, and can be made to correspond to curved terrain when the retaining wall block 1 is installed in the left-right direction.
[0043]
The side wall 4 integrally connects the front wall 2 and the rear wall 3 described above, and each side wall 4 has a length communicating with the space S defined by the front wall 2, the rear wall 3, and the pair of side walls 4. A hole-like opening 4a (see FIG. 3) is formed at a position closer to the front wall 2 than the protrusion 5. Each side wall 4 is formed with a trapezoidal convex portion 4b at the upper end edge from the front wall 2 rather than the middle in the front-rear direction, and at the lower end edge from the front wall 2 than the middle in the front-rear direction. A trapezoidal concave portion 4c (see FIG. 3) into which the convex portion 4b can be fitted is formed. Furthermore, a plurality of circular recesses 4d are formed on the outer surface of each side wall 4 so as to be positioned closer to the rear wall 3 than the protruding portion 5 and spaced in the vertical direction.
[0044]
In this case, the opening 4a is not limited to a single long hole, and may be a plurality of circular or rectangular shapes.

The left and right end edges of the main body 61 are chamfered in a tapered shape.
[0048]
Next, a procedure for constructing a retaining wall using the retaining wall block 1 and the partition plate 6 configured as described above will be described.
[0049]
First, after leveling down the slope that forms the retaining wall and constructing the foundation work 11 with the foundation crushed stone 11a, foundation concrete 11b, and anchor reinforcing bar 11c (see FIG. 5), the retaining wall block 1 is placed on the foundation work 11. Install so as to be continuous in the left-right direction (see FIG. 6).
[0050]
Here, since the rear wall 3 of the retaining wall block 1 is formed slightly shorter than the front wall 2, it is curved in the left-right direction within the range of the difference in length between the front wall 2 and the rear wall 3. It can also be made.
[0051]
  If the first-stage retaining wall block 1 is arranged in the left-right direction, the recess 3a of the rear wall 3 is knocked out to form the opening 3a '. At this time, in order to prevent the backfilling material 12 from flowing through the opening 3a ′, a sucking prevention material 16 (see FIG. 12) is disposed in the opening 3a ′ of the rear wall 3 and, if necessary, the sucking prevention material 16. In addition, a drain pipe (not shown) is disposed in the opening 3a ′. Further, the connecting plate 7 (see FIG. 7) is fixed with bolts across the rear walls 3 and 3 of the pair of adjacent retaining wall blocks 1 and 1, and the pair of adjacent retaining wall blocks 1 and 1 are connected.
