Description

[Detailed Description of the Invention] The present invention relates to an improvement of a seawall block.

2. Description of the Related Art Conventionally, it is already known that a bank protection block for a river or the like has a step surface (a surface horizontal to the ground) at each step and can be used as a staircase.

However, since the steps of such a revetment block were also made of concrete, there was no problem with the revetment function, but the entire revetment was covered with concrete, giving an artificial and unnatural landscape, and it was also considered difficult to use it for walking as a staircase. There were problems such as slippery.

In view of the above-mentioned problems, the present invention makes it possible to selectively place soil, gravel, chestnut stone, concrete, etc. on the stepped surface of the steps, providing a more natural landscape, and also being useful for flood control. The aim is to provide a revetment block with sufficient strength, and its gist is to form a bottom plate that can be stacked along the slope of a revetment, etc., and to form a roughly V-shaped groove from the lower end of the bottom plate to the bottom plate. A revetment block is provided with a receiving plate protruding from the bottom plate, and a through hole extending in the vertical direction is provided in the bottom plate. Hereinafter, the present invention will be explained in detail with reference to the drawings.

The drawings show one embodiment of the present invention, and FIG. 1 is a longitudinal cross-sectional side view of a state in which a step-like revetment is formed on a slope 20 of a river embankment by the revetment block 10 according to the present invention. is the foundation, 40 is the reinforcing bar, 5
0 indicates materials such as earth and sand forming the step surface 16, respectively.

As shown in FIGS. 2 to 5, the revetment block 10 has a bottom plate 11 formed so that it can be stacked along a slope 20, and a bottom plate 11 that extends from the lower end of the bottom plate 11 so that earth and sand for steps can be placed thereon. and a receiving plate 12 protruding so as to form a substantially V-shaped groove.
Inside, there are through holes 1 extending vertically, one each at a quarter of the width in the left and right sides.
3 is provided. Reference numeral 14 denotes a standing plate provided at a quarter of the length in the width direction near the left and right sides.
This structure reinforces the receiving plate 12 and increases its durability, and also allows the revetment blocks 10 to be stacked more accurately. In addition, in order to increase the stability during stacking, the upper end surface 11a, lower end surface 11b, right end surface 11c, and left end surface 11d of the bottom plate 11 have other main revetments located above, below, on the right side, and on the left side. Steps are formed so that they can fit into the corresponding lower end surface 11b, upper end surface 11a, left end surface 11d, and right end surface 11c of the block 10. 15 is a drain hole for water flow. Furthermore, when the present seawall blocks 10 are piled up in a stair-like manner to form a seawall, the seawall blocks 1 on the same level are
A step surface 1 formed on a line connecting the top part 12a of the receiving plate 12 of No. 0 and the upper corner of the bottom plate upper end surface 11a.
6 should be approximately parallel to the horizontal plane.

Next, a method of forming a step-like revetment on a slope 20 of an embankment or the like using the revetment block 10 as described above will be explained. First, as shown in FIG. 1, a foundation 30 made of concrete or the like is placed at the bottom of the slope 20. At this time, reinforcing bars 40 are arranged so as to extend in the vertical direction along the slope 20, and the lower portions of the reinforcing bars 40 are fixed to the foundation 30. The horizontal spacing between the reinforcing bars 40 is equal to the spacing between the through holes 13 in the bottom plate 11 of the revetment block 10. Next, the upper end of the reinforcing bars 40 fixed to the foundation 30 is passed through the through hole 13 so that the back surface of the bottom plate 11 of the revetment block 10 contacts the slope 20, and the revetment block 10 is lowered to a position where it contacts the foundation 30. In this state, the through hole 13
Concrete is poured into the gap between the reinforcing bars 40 and the reinforcing bars 40. Thereafter, the second stage revetment block 10 is shifted horizontally by one-half from that of the first stage, and the upper ends of the reinforcing bars 40 are passed through the through holes 13 and stacked on top. In this state, concrete is poured into the gap between the through hole 13 of the second stage revetment block 10 and the reinforcing bars 40. By sequentially stacking the revetment blocks 10 in this way and pouring concrete into the gaps between the through holes 13 and the reinforcing bars 40, there is no gap between the reinforcing bars 40 and the rebar blocks 10, and they are stably fixed. The seawall blocks 10 stacked together are firmly and integrally connected. Subsequently, in order to form the step surface 16, the bottom plate 11 is
Soil, gravel, chestnut stone, concrete, or the like is selectively placed in a substantially V-shaped groove 17 formed by the receiving plate 12 and the receiving plate 12.

In this way, the revetment blocks 10 are integrally and firmly connected, which not only provides the same solidity as the conventional revetment, but also provides a bottom plate for each stage.
Soil is placed in the approximately V-shaped groove 17 formed by the receiving plate 12 and the receiving plate 12.
By selecting and mounting civil engineering materials such as gravel, chestnut stone, or concrete as appropriate depending on the situation of the revetment, steps as stairs can be constructed using any material.In particular, if earth and sand are selectively mounted, It has a landscape close to nature, allows animals and plants to breed, and can be used as stairs.

As explained above, according to the revetment block according to the present invention, the bottom plate is formed so as to be stackable along the slope of the revetment, etc., and the receiver is protruded from the lower end of the bottom plate so as to form a substantially V-shaped groove with the bottom plate. Since the bottom plate is provided with a through hole extending in the vertical direction, when the revetment blocks are piled up along the slope of an embankment, reinforcing bars are inserted into the through holes to connect the through holes and the reinforcing bars. By pouring concrete, mortar, etc. into the gaps, it is possible to integrate multiple revetment blocks stacked with steps, increasing the strength of the revetment, and further improving the V-shaped grooves formed in each step. By selectively placing civil engineering materials such as earth and sand on the floor, steps can be constructed using any material.In particular, if earth and sand are selectively placed on the earth and sand, it creates a landscape that is closer to nature and is home to plants and animals. It has the advantage that it can be used as a staircase.
