Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses natural stones and concrete revetment blocks in combination to green slopes at high water levels in rivers and the like, protects slopes at river beds and low water levels, and protects water. It is used in combination with a natural stone that purifies the algae and aquatic plants, and can appropriately form riverbeds and slopes at the waterside suitable for habitation and spawning of seafood, aquatic insects and crustaceans. It is intended to provide a block and the seawall.

[0002]

2. Description of the Related Art Blocks made of various concrete are used for the purpose of revetment on the slopes of riverbeds and low water levels of rivers, etc., and the entire riverbeds and slopes are covered with concrete and the surface is covered. The gray concrete surface is exposed, destroying the natural ecosystem and damaging the natural environment and landscape. Therefore, in recent years, there has been a call for "manufacturing of multi-natural rivers" that promotes waterfront development while actively regenerating nature, rather than simply protecting the nature in order to preserve and create abundant nature in harmony with human life.

As a countermeasure against this, there is a trend toward protection of riverbanks by using natural materials as much as possible, and large natural stones are laid as materials for them, or huge stone masonry revetments used as stones as they are. It has undergone work and root consolidation.

[0004] In the slope, it is planted in the gap between the large natural stones and planted for greening. In the waterside, algae adhere to the surface and are used as bait for seafood. It becomes a habitat for aquatic insects, where small stones are clogged to form a habitat for aquatic insects. It becomes a place.

However, in order to be able to resist the running water of a river, it requires 1 to 3 tons of weight per piece, and in order to match the surrounding landscape, it is good to use round boulders which are natural products. Needless to say. Natural stone materials such as boulders, especially those with a well-shaped shape, are becoming difficult to obtain, and if the shape and size are tried to be adjusted, the price will increase. In addition, embedding and mounting the rounded heavy objects one by one in the slope is labor-intensive and runs counter to labor saving and labor saving required in recent years.

Further, as a method for solving this problem, Japanese Patent Laid-Open No. H6-6
-108437 has been published as an example, and although the amount of large natural stone used is reduced, it is necessary to form a through hole in the stone, which requires a large machine and it takes time to penetrate. The cost is enormous, a specialized skilled worker is required to pass the connecting wire through the through hole, and it is troublesome and time-consuming, which also causes an increase in cost. It certainly matches the natural landscape, but it must be said that it is far from labor saving and labor saving.

[0007]

As described above, the function of protecting slopes and riverbeds from scouring and collapsing, as well as making plants grow in the high water portion of the slope of the river and seafood in the low water portion of the slope. ，
Equipped with a function to allow aquatic insects and crustacean organisms to live, and more economically supplied by using a combination of natural stones and concrete revetment blocks with slope protection and riverbed consolidation that match the natural environment. Is what you are trying to do.

[0008]

Means for Solving the Problems The present invention has been studied to solve the problems of the conventional ones as described above, and has a continuous megalithic or megalithic pattern on the upper surface of the frame portion formed by the concrete revetment block. It was formed as a projecting part and was made achievable, and natural stone materials were loaded into the frame to plant trees and to properly construct revetments and root repair works as a habitat for seafood and aquatic insects. It has succeeded in obtaining easily, and is as follows.

[0014]

[Function] Blocks of megaliths are laid on the slopes and riverbeds at the water's edge of the river, set so that they are connected to each other, and natural stones such as cobblestone are loaded between the frames so that algae can be placed on the surface of the stones. Since sediment adheres to the gaps and deposits sand and water plants grow, the surroundings and voids of the stone provide a habitat for seafood, aquatic insects and crustaceans, such as feeding grounds, spawning grounds, habitats, etc. A waterfront space.

Various voids are communicated between the packed stones to measure ventilation and water flow to the back soil, and to flow water between the stones through the protrusions of megaliths or megalithic patterns. As a result, the suspended solids in the water are deposited on the surface or adsorbed by the viscosity of the biofilm, and the microorganisms growing on the surface absorb and decompose the pollutant to remove it. In addition, in a site where there is a concern that the material will be sucked out from the natural ground, the substrate can be prevented by using a porous concrete plate, and the purification function can be further improved.

By using this block on slopes of high water floors and high water level parts, by burying soil between stone materials and planting, trees such as willows, grass, flowers etc. can be removed from the gaps of natural stone materials. It forms a natural revetment where plants grow and the entire slope is covered with green, and it also provides a comfortable environment for insects and larvae living in the gaps between soil and stone.

The frame formed by this block prevents sliding and flow of the packed stone materials and outflow at the time of flood, and the surface of the frame is formed with a megalith or a megalith pattern, and stones are also sandwiched between them, so that the general Shows a landscape covered with natural stones and has no discomfort, and coloring the pattern surface makes it almost natural.

Further, since the stones to be packed are of any size and shape, it is economical because the stones generated at the site can be used as they are, and at the same time, the blocks are installed and the natural stones are packed, so speedy construction is possible. This makes it possible to meet the labor saving and labor saving demanded in recent years.

When used on a slope where there is a risk of consolidation due to rapid flow velocity, rapid flow, or turbulent flow during heavy rain, a net or lattice-shaped synthetic resin sheath formed on the upper surface of the block is used. To prevent the outflow of natural stone by attaching and fixing nets of metal and metal materials, providing a greening slope and a good habitat for aquatic life for many years.
