[Action]

The revetment for revetment according to the present invention is constructed by laying a reservoir block for revetment of the present invention, which is provided with a water storage recess at the center of the upper surface, leaving the required width of the outer circumference of the block body on a stepped or flat foundation. Because it is horizontal, you can easily walk on it and play there, and there is no danger of sliding like a conventional sloped seawall. Gravel, rocks (or crushed stones), etc. collected around the site are stored in the water storage pits of each block, and if necessary, plants such as reeds are planted in the pits, where seawater, river water, Rainwater accumulates, and together with the above-mentioned gravel, rocks, etc., increases the total weight of each block, further stabilizes it, and promotes plant growth. In addition, microorganisms such as animal and phytoplankton occur and inhabit the reservoir water over time, and this phenomenon is repeatedly introduced into the sea or river water due to high tide, waves, or rising water, which may cause the propagation of fish nearby. Contribute.

【Example】

The revetment water storage block a of the present invention is made of reinforced concrete having a flat rectangular shape and has a required thickness, and a water storage recess 3 is provided at the center of the upper surface of the block main body 1 having a required outer peripheral width 2. The depth, area and shape of the water storage recess 3 can be arbitrarily determined within a range that does not impair the required strength of the seawall. Reference numerals 4 denote vertical holes penetrating vertically at four corners of the block main body 1, ie, corners of the required outer peripheral width 2, and the upper ends thereof are large-diameter openings 4 '. Reference numeral 5 denotes a left or right long side edge portion of the block body 1 and a vertical hole penetrating at a position parallel to the vertical hole 4, the upper end of which is connected to a concave groove 5 'opening at the left and right long side edge. Let me. Reference numeral 6 denotes a drainage hole in which the bottom of the water storage recess 3 communicates with the outer surface of the block main body 1. The drainage hole shown in FIGS. 1 and 2 is opened on the outer peripheral surface of the block main body 1, and FIG. In the structure shown in FIG. 1, the opening is formed on the outer surface of the bottom wall of the block body 1. The drainage hole 6 is formed by embedding a synthetic resin pipe 6 ′ made of hard vinyl or the like having a funnel-shaped mouth at the inner end. The amount of drainage from the water storage recess 3 is adjusted by a rubber plug fitted into the funnel-shaped mouth. Alternatively, it is performed with a wooden stopper (not shown). The water storage revetment according to the present invention is constructed by laying the revetment water storage block a having the above configuration stepwise or flat. FIG. 4 shows an embodiment of a step-like storage revetment, in which stones are deposited along a slope of a beach to form a step-like foundation b, and each step of the step-like foundation b has the above-mentioned seawall for revetment. The water storage blocks a (in which the drain holes 6 shown in FIGS. 1 and 2 were opened on the outer surface of the peripheral wall) were arranged side by side, and the front end of the upper block a was mounted on the rear end of the lower block a. It is laid in the state. In the above, blocks a and a adjacent to each other on the same stage on the left and right
Inserts the two legs 7 ', 7' of the inverted U-shaped stopper 7 through the concave grooves 5 ', 5' which are aligned with the vertical holes 5, 5 and strikes the ends thereof on the base b. Lower block a,
a, a rod-shaped stopper 8 having a head 8 'is inserted into the longitudinal holes 4, 4 which coincide with each other through a large-diameter opening 4' of the upper stage, and its tip is beaten to a foundation b; The openings 4 ′, the vertical holes 4, the concave grooves 5 ′ and the vertical holes 5 are filled with mortar, and metal fittings 7 and 8 are embedded therein (FIGS. 5 to 7).
See figure). FIG. 8 shows an embodiment of a flat revetment, in which stones are deposited on a riverbank to form a flat foundation c, and the revetment water storage block a (a drain hole 6 shown in FIG. (Opened on the outer surface) are arranged vertically and horizontally adjacently. Blocks a, a adjacent to the left and right sides of the flat seawall are inserted with both legs 7 ', 7' of the inverted U-shaped stopper 7 through concave grooves 5 ', 5' which are aligned with the vertical holes 5, 5, respectively. The tip is struck on a foundation c, and the metal fitting 7 is embedded in a mortar filled in the vertical hole 5 and the concave groove 5 '(see FIG. 7). In this case, in the vertical hole 4, the rod-shaped stopper 8
May be appropriately determined according to the situation at the site. In both of the above embodiments, the gravel 9, rocks 10 (or crushed stones) and the like collected around the site are stored in the water storage recess 3 of each laid block a.
Plant. In addition, seawater, river water, rainwater, and the like are stored in the storage recess 3 of each laid block a.
Together with 10 mag, it increases the total weight of each block a, further stabilizes it, and acts on the growth of the plant 11. Since the amount of water stored in the reservoir is appropriately replenished or drained to the lower block a or to the foundation ground through the drainage hole 6 in an appropriate manner, the water does not rot in the water storage recess 3. In addition, microorganisms such as animal and phytoplankton are generated and inhabit in the water in the water reservoir 3 with time, and the phenomenon that they are taken into the sea or river water by high tide, waves or rising water repeatedly occurs, and the breeding of fish in the vicinity To contribute.

[Effect of the invention]

As is clear from the above description, the water storage block for revetment of the present invention is provided with a water storage recess at the center of the upper surface, leaving the required width of the outer circumference of the block body, and is laid on a step-like foundation or flat foundation. It can easily build a stair-like storage seawall or a flat storage seawall, and since its laying surface is horizontal, it can be easily walked on and played there, and it can slide like a conventional sloped seawall. There is no danger, and gravel, rocks (or crushed stones), etc. collected around the site are stored in the water pits of each block, and if necessary, plants such as reeds are planted in them. Seawater, river water, rainwater, and the like are stored, and together with the above-mentioned gravel, rocks, etc., increase the total weight of each block, further stabilize it, and promote the growth of plants. In addition, microorganisms such as flora and fauna plankton occur and inhabit over time in the water in the above-mentioned reservoir, and this phenomenon is repeatedly taken into the sea or river water due to high tide, waves, or rising water, and the propagation of fish in the vicinity To contribute. In these stairs and flat reservoirs,
The blocks adjacent to the left and right are inserted into the respective vertical holes of the concave grooves that match each other, by inserting the two legs of the inverted U-shaped fastener through the concave grooves and striking the tips thereof to the foundation, and In the revetment, furthermore, the upper and lower blocks,
By inserting a bar-shaped stopper having a head through the large-diameter opening of the upper one into the corresponding vertical holes and striking the tips on the foundation, they are connected integrally and locked to the foundation. Therefore, it will be strong with the required strength as a revetment.
