Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block for revetment and the creation of a concrete block revetment, which protects slopes such as rivers, lakes and shores, bottoms such as sinkers, and controls the flow of water. The present invention aims to provide a concrete block for revetment and a revetment for rivers which can be obtained relatively easily and accurately using the concrete block.

2. Description of the Related Art Since ancient times, some methods have been taken for the construction of seawalls and water control works at the waterfront of rivers in Japan. In other words, generally, stones are piled up in the shape of a stone wall, or gabions are used, and stones are loaded into the stones and laid horizontally on the shore of a river, or coarse bunches and timbers are assembled in a grid pattern and filled with natural stones. The woodworking floor is laid. Of course, instead of wood, rectangular rectangular timbers made of concrete can be assembled in a grid pattern and connected at the intersections with iron wires or bolts, and the space can be filled with natural stone to form revetments, sunk works, or flood control works. Has been done.

[0003]

In any case, the conventional revetment, sill work or water work as described above has a large number of man-hours and has various problems. That is, there is a disadvantage that a simple pile of stone materials in the shape of a stone wall cannot achieve a stable and accurate revetment purpose in the event of a flood. In addition, the one using a gabion does not match the demands of today's times because it takes time to arrange the size of the stones to be used and to load the stones into them. In addition, it is difficult to obtain rough gravel as a raw material for rough sunk floor work, and there are few skilled workers who can perform it because it is a traditional method from old times.

Although there is no such problem in the woodworking floor, it is needless to say that precious wood is used as a natural resource in a large amount and it takes time to assemble and fill. Furthermore, when this concrete timber is used instead of this wood, it can be manufactured anywhere, but the weight is heavy, so it will take time and effort to assemble it with a heavy machine, of course, the surface of the concrete is the same as it is, so the natural feeling is greatly changed. , There is a disadvantage that it becomes difficult to adapt to the surrounding environment.

[0005]

In addition, the corners are filled with a combination stone material by using the auxiliary block 9b for each step, and the filling stone material 8 is appropriately made of a vinyl chloride pipe, a ceramic pipe, a small box culvert, a fume pipe, or the like. It has been shown that the shape body 16 is installed vertically and is filled with a vegetation material in a roll shape or a bag shape made of natural fibers such as earth and sand or coconut fiber, and vegetation of aquatic plants such as reeds, reeds, and buds, or running water. The seeds brought in by the plant form a floating island by growing naturally, providing a resting place and a place for birds to contribute to plant purification and landscape. In addition, by simply forming a hollow portion, it can be used as a stagnation portion and can be used as a shelter for large fish or as an evacuation site for small fish during floods.

In FIG. 15, as in FIG. 9, when the bank is formed as a continuous seawall along the flow at the water's edge, the stacking height is further increased to form a round or square tubular material or U-shaped block in the middle portion. It is shown to be installed upside down horizontally, and will be used as a habitat for cavities and other seafood such as eels and catfish, and as an evacuation site in the event of floods. The tubular body 16 and the U-shaped block 17 may be made of synthetic resin, ceramics, or the like other than concrete.

FIG. 16 shows a revetment by the frame-shaped block 1 of FIG. 3 in which a pattern is not formed on the surface, in which the plants 24 are also allowed to grow on the surface, that is, the revetment as described above. A sheet-like vegetation material 19 made of natural fibers such as sponge or palm fiber material is integrally formed by using a mesh material 20 as in the upper part by a method such as bonding or sandwiching, and the end portion of the mesh material is bolted.

By letting the seeds grow spontaneously and grow like floating islands, it is possible to easily green the water's edge and contribute to water purification by plants. The mesh material is made of synthetic resin or various metal materials.

FIG. 17 shows a plan view of a water control structure in which the present invention is formed so as to project from a shore into a water flow, and serves as protection of the shore at the waterside and a large bay on the back of the water control. It forms a part of the area, where sediments and other materials naturally accumulate to form rivers and pools, which serve as a habitat for a wide variety of aquatic organisms. It goes without saying that this water work may be formed by arranging the frame blocks in parallel as shown in the left figure of FIG. 17 or by combining the rows as shown in the right figure to form only the water work alone. , FIG. 14
As described above, the tubular body or sheet-shaped vegetation material shown in FIG. 16 may be used. Also, the frame block 1 of FIG.
Use the longitudinal direction to lower the central part in the transverse direction of the river,

That is, in this case, as shown in FIG. 18, the upper portion of the laminated water-controlling structure is formed by forming the concave portion 31 in which the central portion of the river is lowered and the convex portion 32 on the side of the no-shore portion. The water flow between the stones 8 promotes the consolidation of the sediment deposited on the upstream side and the function as a sabo is maintained for a long time, and a sabo dam with a longer service life than a simple concrete revetment can be obtained. . Even when this is used as a weir, it is possible to take in air (oxygen) into the water by passing water and facilitate the habitation and movement of aquatic insects and cave fishes such as eels and catfish.

FIG. 19 shows another frame-shaped block 21 according to the present invention, and FIGS. 20 and 21 show an example of a seawall constructed using this frame-shaped block 21. . That is, the frame block 21 shown in FIG. 19 can be provided with the various patterns 11 to 14 as described above on its surface, but on the front side when the seawall is formed as shown in FIGS. The side portion 1a located is 3 to 5 minutes on the front surface (1: 0.5), as clearly shown in FIG.
Is a trapezoid in cross section, and the connecting hole 3 in this portion is also inclined in the height direction, which is higher than the lower frame-shaped block. It is configured to have a trapezoidal cross section as a whole revetment by adopting a narrower one.

That is, the one in which the revetment is trapezoidal using the frame block 21 as shown in FIGS. 19 to 21 is shown in FIG.
As shown in 1, it is stable against the action from the frontal water area and stable against the earth pressure on the backside debris layer 22 side on the backside, and at the same time, it aims to pass water to the backside soil at the low water position The waterfront is sloping to create a waterside that is kind to nature, and construction with outstanding durability can be performed.

According to the present invention as described above, a set of four conventional logs and concrete squares is used as a concrete block formed in a lattice form, and each corner portion has a thickness. By connecting holes that are opened in the vertical direction, the stacked blocks can be easily and accurately connected to each other, which makes it easy and stable to construct revetments, sill works, and flood control works. The inner hole is filled with concrete lumps, which are stone materials and construction waste generated at the construction site, to properly form revetments, sunk works, and water control works, and the assembled composite strength is greatly improved compared to the conventional one. It has the merit that the construction speed is greatly improved and no skilled workers are required.

Further, since the thickness of one of the rod-shaped portions oppositely provided so as to form the lattice frame is made different from the thickness of the other rod-shaped portion, they are laterally connected in a plane. It does not affect the running water because it allows water to flow to and from the grid frame.

Furthermore, by forming a natural member-like pattern such as wood or stone on the concrete block formed in the lattice frame shape, the appearance of the concrete block properly blended with the surrounding natural landscape is formed. To do.

A plurality of grid frame-shaped concrete blocks as described above are laminated in a state where a space is formed in a plane and vertically alternately, and are connected to connection holes provided at corners of the concrete blocks. The material is inserted and connected, and by loading the stone material in the lattice frame, it is stable and has an appropriate thickness and forms an appropriate water passage between the connected concrete blocks to purify water. It is possible to form a stable revetment, sill work, and flood control that can be expected to be effective and can sufficiently withstand the water pressure during a flood, etc., relatively easily and effectively.

Further, in the lattice frame-shaped portion as described above, a cylindrical or inverted U-shaped through-hole forming member made of concrete or various materials is installed horizontally or vertically depending on the purpose together with the stone material, or the upper portion. By providing a sheet-shaped vegetation material on the seashore, a cavity suitable for the rest or habitation of fish and other aquatic organisms can be formed in revetments, sunk works, and water control works that have the above-mentioned effects, and further planting can be achieved. It brings water closer to nature and contributes to the purification of water.

[0032]

According to the present invention as described above, it is apparent that concrete blocks can be used to construct a simple and appropriate revetment, sill work and flood control in a river, that is, a suitable thick layer. Due to this, revetments, sunk works and water control works can be freely formed in any length and height range to properly protect necessary riverbanks, and to allow favorable growth or rest of fish and other aquatic organisms and waterside plants. Those that form an environment favorably and that match the natural environment and correspond well to the natural landscape, and that facilitate the construction of concrete blocks, and that can form seawalls with sufficient durability, strength and controllability. Therefore, the invention is industrially highly effective.
