[0025]
The construction method of the retaining wall using the blocks 1, 1 a to 1 e and the first and second partition plates 7, 7 a configured as described above will be described below.
[0026]
[Direct loading]
16 to 18 show a direct stacking method in which the front plates of each block are stacked in a vertical plane. In this case, the foundation 10 is inclined so that the back side is lowered only by the inclination angle α degrees of the block 3 of each block, and is formed in a shape that matches the shape of the lower surface of the block. Stack in a basic position with the head tilting downward against the front plate. As a result, the blocks are stacked such that the front plate 2 thereof is vertical.
[0027]
At this time, if necessary, the ½ height type block 1a was arranged in the lowermost layer part and the uppermost layer part, and the basic type block 1 was arranged in the middle part. Further, as shown in FIG. 17, at the end portion in the extending direction of the retaining wall, as shown in FIG. 17, the left / right ½ width type block 1b (1c) and the ½ height / width type block 1d (1e) are used. ) Is used.
[0028]
In accordance with the stacking of the blocks 1, 1a to 1e, the first partition plate 7 is engaged between the blocks of the blocks. At this time, the first partition plate 7 is parallel to the front plate 2. At this time, by engaging each partition plate 7 with the recessed grooves 6a and 6b on the rearmost end side of the stand, each partition plate 7 becomes a rear wall of the retaining wall, and between the front plate 2 and the rear wall. Pack the filling material 11. In addition, 12 is a top plate and 13 is a backfill material.
[0029]
As shown in FIG. 18, if each block described above is prepared by changing the length of the copy, use blocks in which the copy becomes shorter from the lower layer to the upper layer, and the magnitude of the back pressure from the natural ground. Retaining wall is constructed to match. And in this retaining wall of direct stacking, the back of each block that constitutes the retaining wall that is vertical is inclined backward by the inclination angle α as described above, so that the rear side of the retaining wall Even if earth pressure acts from the natural ground side, it is supported by the above-mentioned inclination, and the collapse of the retaining wall to the front side can be prevented.
[0030]
In addition to the rear end portion of the guard, the partition plate 7 is engaged with the recesses 6a and 6b in the longitudinal direction of the guard 3 as shown by a chain line in FIG. A plurality of them may be arranged. In this case, each partition plate 7 can be arranged independently by one by separating and holding each partition plate 7 between the stores.
[0031]
[Tilt stacking]
FIG. 19 shows a diagonal stacking method in which the front plates of each block are stacked so as to be inclined. Also in this case, the blocks 1, 1a to 1e are stacked on the foundation 10 that is inclined so that the back side is lowered, in the same manner as in the case of the above-described direct stacking, with the front plate inclined in the backward tilting direction. .
At this time, the blocks 1 and 1a to 1e are stacked in an inverted posture in which the blocks 1 are inverted in the vertical direction with respect to the case of direct stacking. As a result, the substantial inclination of the blocks 1, 1a to 1e retainers 3, 3a to 3e constituting the retaining wall to be obliquely stacked is the same as that of the conventional structure in which the retainers protrude in a direction perpendicular to the front plate. With respect to the seed block, the inclination is reduced by an angle of inclination α with respect to the front plate.
[0032]
That is, the inclination angle theta ₂ of the refrain whereas the inclination angle of the retaining wall is theta ₁ becomes smaller than the inclination angle theta ₁ of retaining wall becomes (θ ₁ -α), the conventional block theta ₁ = the inclination of the refrain is reduced is the relative and theta _2. As a result, the retaining wall inclination angle θ ₁ can be increased without increasing the conservative inclination angle θ ₂ as compared with the conventional block of θ ₁ = θ ₂ , and a retaining wall with a large inclination angle can be easily obtained. Can be built. Also at this time, the first partition plate 7 that is parallel to the front plate is used. The inclination of the foundation 10 at this time is also reduced by α °, and the height of the front side of the foundation 10 is lowered accordingly.
[0033]
[Tera slope stacking]
FIG. 20 shows a temple gradient stacking method in which the blocks are stacked so that the front surface has a concave shape in the vertical direction. Also in this case, the respective blocks 1, 1a to 1e are stacked on the foundation 10 inclined at the same angle as in the case of direct stacking so that the respective front plates sequentially have a temple slope in the same basic posture as in the case of direct stacking. Also in this case, a retaining wall having a strong resistance to the pressure from the natural ground side can be constructed as in the case of direct stacking. In addition, it gives a soft feeling like a castle wall from a landscape perspective.
[0034]
[Vegetation pile]
FIG. 21 shows a vegetation stacking method in which the top end of each step is opened upward and vegetation is enabled at this portion. In this case, on the foundation 10a whose upper surface is horizontal, the blocks 1, 1a to 1e inverted up and down like the diagonal stacking are stacked so that the lines connecting the respective front plates are inclined to the rear side.
[0035]
As a result, the front plate of each block is inclined forward with respect to the horizontal copy, and the top end of each block is opened upward. Therefore, the planting soil 14 is filled in this portion and the vegetation 15 is planted. .
[0036]
Since the front plate in the case of this vegetation stack is opposite to the inclination of the retaining wall, the second partition plate 7a is used as the partition plate that closes the rear end of each guard. In the case of this vegetation stack, in order to prevent the planting soil 14 from being mixed with the filling material 11, the partition plate 7a is also installed near the tip.
[0037]
【The invention's effect】
According to the present invention, during direct stacking, it is possible to stack the stand with the back side inclined downward, and during this direct stacking, the resistance to the pressure from the natural ground increases, and it is difficult to collapse forward. Can be stacked.
[0038]
In addition, according to the present invention, by turning the building block upside down, the posture of the copy with respect to the front plate is changed in the vertical direction, and in addition to the above-described direct stacking, Each retaining wall can be constructed firmly by gradient stacking and vegetation stacking. Further, the inclination of the foundation during oblique stacking can be reduced, and the height of the front end side thereof can be reduced.
