Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a revetment for a waterway formed by connecting a concrete product for forming a waterway having a side wall and a bottom part to form a waterway.
[0002]
[Prior art]
Conventionally, revetments for concrete waterways have been formed to send rainwater, agricultural water, drainage, etc. to the sea, rivers, lakes, ponds, water purification plants, etc. Therefore, consideration is given to ensuring the necessary amount of water and avoiding unnecessary environmental pollution to the outside. However, this concrete waterway revetment was not easily inhabited by aquatic plants and aquatic animals, so it was released from the surrounding natural world and was not easily harmonized with nature.
[0003]
Therefore, in Patent Document 1, the side wall portion is formed so that a large number of stones can be stored and held between two mesh plates arranged opposite to each other, and the bottom portion is formed by a rib connecting the side walls. Revetment is disclosed, aquatic plants are rooted, aquatic animals inhabit between stones and stones, can be purified by natural purification action, and provide a waterway close to the natural environment Proposed.
[0004]

Japanese Patent Laid-Open No. 2002-88740
[Problems to be solved by the invention]
However, the above-mentioned waterway revetment completely eliminates the advantages of concrete revetment, and the wall surface and bottom surface are eroded and stable strength against earth pressure cannot be ensured. In addition to not being able to feed the required amount of water, there are drawbacks such as unexpected temporary inflow of wastewater that cannot be purified by natural purification, which may cause unnecessary environmental pollution to the outside. .
[0006]
The present invention improves the conventional drawbacks as described above, and has the characteristics of a concrete channel such as ensuring stable strength against earth pressure without eroding the wall surface and bottom surface, The purpose of this project is to provide a revetment for waterways that can coexist with each other and harmonize with nature by making it an optimal habitat for animals and other organisms.
[0007]
[Means for Solving the Problems]
The present invention achieves such an object, and a steel plate is sandwiched and fixed so as to protrude to the water channel side at a joint portion of a plurality of concrete products for forming a water channel formed continuously, and formed into a U-shape. A revetment for a waterway characterized in that each attachment plate attached to both ends of a mesh-like member is fixed to a protruding portion of the different steel plate, and a filler capable of forming a gap is filled in the space between the mesh member and the waterway wall. It is.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the revetment for waterways of the present invention will be described according to the illustrated embodiment.
[0009]
1 to 4, reference numeral 1 denotes a waterway revetment according to the present invention. The waterway revetment 1 includes a water channel forming concrete product 10, a steel plate 20, a mesh member 30, and a filler 40.
[0010]
As shown in FIG. 1, the concrete product 10 for forming a water channel is a three-sided concrete product made up of side walls 11 and 11 and a bottom 12 formed of concrete or the like as a main material. As shown in FIG. The end portions (joint portions) 13 of the side walls 11 are used so as to be in close contact with each other. In the case of continuous installation, it is fixed by various methods such as a method of locking with a bolt or a method of fitting in a groove, and leakage of water is prevented with a mortar as necessary.
[0011]
As shown in FIG. 2, the steel plate 20 is sandwiched and fixed to the joint portion 13 of the concrete product 10 for forming a water channel so as to protrude toward the water channel, and thus the concrete product 10 for forming a water channel is used. Therefore, it is possible to easily and reliably attach the concrete product 10 for forming a water channel in a continuous manner. The steel plate 20 may be another material as long as it has high strength and is corrosion resistant. Furthermore, when corrosion resistance is required, it is desirable to use stainless steel.
[0012]
As shown in FIG. 4, the mesh member 30 includes a mesh portion 31 formed in a U-shape and attachment plates 32 attached to both ends thereof. The mounting plate 32 is locked to the steel plate 20 by a locking tool 33. The shape of the mesh part 31 should just be a substantially U shape, and can change according to the shape, quantity, etc. of the filler 40. As for the shape and roughness of the mesh portion 31, it is desirable to select an appropriate shape according to the shape and quantity of the filler 40, and the range in which the filler 40 does not flow out and small fish can enter and exit. It is desirable to have a shape and roughness. If the mesh part 31 and the mounting plate 32 are plated, they can be used semipermanently.
[0013]
The filler 40 is capable of forming gaps such as stones such as crushed stones, cobblestones and chestnuts, thinned timbers, and soda bundles, and many moderate gaps are formed between them, and aquatic plants are easy to grow. It is desirable that a large surface area be formed, and that a space should be formed where aquatic animals can feed and enter and exit.
[0014]
Here, an example of the method of constructing the revetment for waterways 1 of the present invention will be described in detail.
As shown in FIG. 2 and the like, the steel plate 20 is sandwiched between the joint portions 13 of the water channel forming concrete product 10 so as to protrude toward the water channel, and the water channel forming concrete product 10 is installed while being fixed. At this time, the concrete product 10 for forming a water channel and the steel plate 20 can be fixed by various methods such as a method of locking with a bolt or a method of fitting in a groove. A mounting plate 32 attached to the tip of the mesh-like member 30 bent into a U-shape is fixed to the water channel side protruding portion of the steel plate 20 with a locking tool 33 such as a bolt and a nut. As shown in FIGS. 5 and 6, crushed stones (kuriishi) are packed between the mesh member 30 and the channel wall of the concrete product 10 for forming a channel. Alternatively, as shown in FIG. 7 and FIG. Alternatively, both can be used together or a bundle of soda can be stood. The crushed stones (chestnuts), thinned wood, and soda gaps packed between the mesh members 30 serve as a place for living aquatic plants and aquatic animals, and also contribute to the promotion of water purification. The mesh member 30 can be easily replaced even if it corrodes.
[0015]
【The invention's effect】
As is clear from the above description, the revetment for waterways of the present invention has the characteristics of a concrete waterway such as ensuring stable strength against earth pressure without erosion of the wall surface and bottom surface, and aquatic plants. By making it the optimal habitat for living organisms such as water and aquatic animals, aquatic plants can be prospered and landscapes close to nature can be maintained, while food for organisms such as small fish can be supplied. It is possible to achieve further harmony, coexistence and co-prosperity with living organisms, and harmony with nature.
