Description

[Detailed Description of the Invention] "Industrial application field" The present invention lays and connects many slopes on rivers, coasts, etc., and embanks on them to protect the environment and slide down the embankments. The present invention relates to a revetment block designed to prevent

“Prior art” Conventionally, on the wrong bank of the slope, a large number of blocks are laid and the reinforcing bars are inserted into the blocks to connect the blocks to cover the slope, or rod-shaped blocks are combined in a grid pattern and the grid The boulders were laid inside the shape, or grass was planted to protect the seawall.

"Problems to be solved by the invention" When configured as described above, the natural environment is destroyed, and in the case where many blocks are laid and the reinforcing bars are inserted into the blocks, earth and sand are gradually sucked out from between the blocks. ,
Blocks are suspended in the air, and the reinforcing bars are cut, the blocks come apart, and in the case of a combination of rod-shaped blocks, part of the blocks floats or the bottom sand is sucked out. Then, there was an adverse effect such as disassembling and failing to fulfill the role of the seawall.

"Means for Solving the Problem" Therefore, the present invention has been proposed in order to eliminate the above-mentioned inconvenience, and the configuration thereof is such that two opposite corner portions of a rectangular plate-shaped body are When the plate width is L, a notch corresponding to L of the plate is provided, and a through hole is provided in the plate width direction at the center of the remaining plate-shaped part provided with the notch, and one long side of the plate is An upper protrusion is provided on the side edge and the upper peripheral edge of one notch, and a lower protrusion is provided on the remaining other long side and the lower peripheral edge of the other notch on the other side. It is provided with a protrusion. To implement the present invention, for example, on a slope of a river or a coast, a large number of blocks can be formed in a straight line by laying the blocks so that the cutouts of the adjacent blocks fit to each other. When a large number of rows are laid, the through holes also communicate with each other, and the reinforcing bars are inserted into the whole to integrate the whole, and embankment is performed on it. By doing so, the block protects the slope well, prevents the embankment on the block from sliding down, and protects the environment because the slope surface is covered by the embankment. It is a thing.

The structure will be described with reference to the drawings. Reference numeral 1 denotes a plate-like body having a rectangular shape in the drawing and having an appropriate thickness. Reference numerals 2 and 3 are notches provided in two opposing corner portions, and the width thereof is a width corresponding to L / 2 when the plate width of the plate-shaped body 1 is L. Reference numeral 4 denotes a through hole, which is provided in the plate width direction at the center of the remaining plate-like portion 1 ′ provided with the notches 2 and 3. Reference numeral 5 denotes an upper ridge provided on one long side, one side, and the upper peripheral edge of one notch 2 of the plate-shaped body 1. Reference numeral 6 denotes another long side of the plate-shaped body 1, the other side, and a lower ridge provided on the lower peripheral edge of the other notch. Reference numeral 7 denotes a large number of protrusions provided on the upper surface of the plate-shaped body 1. The side surface of the protrusion 7 above the slope is steeper than the side surface below the slope. The upper peripheral edge and the lower peripheral edge of the plate-shaped body 1 are formed in an arc shape. Reference numeral 8 is a reinforcing bar, 9 is an embankment above the block, and 10 is a waterproof sheet laid under the block.

[Operation] Since the present invention has the structure as described above, in order to construct the structure, the waterproof sheet 10 is laid on the slope of a river or coast, and the cutouts 2 and 3 of the block are provided on the waterproof sheet 10. By engaging the plate-like portions 1'of the adjacent blocks, the upper ridge 5 on one side overlaps with the lower ridge 6 on the other side, and similarly, when a plurality of rows are juxtaposed, as shown in FIG. All the through-holes 4 are communicated with each other, the reinforcing bars 8 are inserted into the through-holes 4 to form a block connecting body, and an embankment 9 is applied to the upper surface of the connecting body.

[Advantage of the Invention] According to the present invention, the plate-shaped portions ′ of the adjacent blocks are engaged with each other by abutting the notches 2 and 3, and the upper protrusion 5 is connected to the lower protrusion 6 of the adjacent block. Since it is constructed only by superposition, in the case of a large block, the work of fitting the concavo-convex stripes of the adjacent blocks can be saved and the work is extremely easy. All blocks are integrated by communicating with each other and inserting the reinforcing bar 8 into them, and the upper protrusions 5 and the lower protrusions 6 are overlapped with each other, so there is no gap and suction of sediment below the block is prevented. Well, the purpose of revetment is achieved, and if the embankment 9 is applied to the surface of the block, the concrete surface is not exposed like the conventional block. Can be protected and block There is a protrusion 7 on the surface of the ground, on which the embankment 9
When it is applied, it can prevent sliding down. Further, when the embankment 9 is not provided, even when walking on the slope, it is prevented from slipping down, and the flow is relaxed, and the bank can be well protected.

In addition, by making the upper and lower peripheral edges of the corners of the upper projecting ridge 5 and the lower projecting ridge 6 of the plate-shaped body 1 arc-shaped,
When the block bends, even if the peripheral edges come into contact with each other, the block is easily bent, and the block is prevented from being damaged, and the waterproof sheet 10 on the lower surface of the block is not hooked and damaged. Further, by providing the waterproof sheet 10, it is possible to prevent the suction of dirt and sand from the lower surface of the block. By making the side surface above the slope of the projection 7 steep, the slip of the embankment 9 is made more effective.
