Description

Shore protection structure of using cramps

The present invention provides a habitat for fish, etc., when constructing slopes such as rivers, and relates to a flow-rate damping revetment structure using a cramp to prevent damage from flooding by minimizing scouring due to the flow rate.

More specifically, by integrally connecting the rock and the rock placed on the inclined soil surface as a connecting member, it prevents the rock from flowing down from the soil surface, has a force against the flow rate and earth pressure, and between the rocks The present invention relates to a flow decay-type revetment structure using a bracket that provides a habitat for fish and the like and prevents scouring due to the decay of the flow rate of water flowing into the pore.

In general, in the construction of rivers, reservoirs, etc. around the city center, the slopes cover various shore protection members mainly on concrete structures to protect the levees by artificially damaging and deforming the slopes of natural forms of mountains or rivers. The lower base of the revetment member protects the foundation by installing a gabion filled with a mesh-shaped stone composed of a polygonal concrete foundation or wire.

The various riversides are composed of various natural ecological and natural environments according to the winter season, the flow of the river, and the surrounding environment. When the circumference of the river flow is constructed with artificial concrete or stone, temporary beauty and dimension are exerted.

However, such levees have erosion and scour phenomena due to the flow rate over time, causing tremendous damage to the natural ecosystem due to the destruction of the vegetation zone, resulting in a huge cost and time due to the reconstruction of these structures.

In addition, various fish, algae, as well as various kinds of plants are naturally extinct because they lose their habitat by the artificial structure. As a result, it has been pointed out as a factor that ultimately impairs the living environment of human beings by falling into dead rivers and lakes that have lost their basic functions such as natural purification, providing fresh air, and providing urban retreats.

Recently, in order to improve the workability or improve the aesthetics of slope protection construction, the Stonenet method is a method in which a large number of stone types are arranged in advance in a workshop, and then the stones are fixed by using a crane or the like. stone net) (wrap stone method) is used.

As shown in Figure 1, the prior art rock using the prior art, even after stopping the soil surface using the heavy equipment, and stacked a large volume of rock stacked, but the gap between the large rock and rock In order to increase the cohesion of the rock by filling a medium-sized gravel or small size stone, it is possible to prevent the flow of rock from the slope due to storms and floods.

The above-described revetment structure loses habitats of fish, algae, etc. due to the gravel filled in the pores of the rock, and thus has a problem of accelerating water quality or environmental pollution due to the loss of its natural purification function.

In addition, the fluid loses its ability to attenuate the flow velocity of the fluid when it is in contact with the rock or river structure, causing scour caused by the flow velocity of the fluid, and when some rocks are separated from the soil surface, adjacent rocks are separated in series. The flooding caused by the collapse of the embankment has the problem of causing valuable property and casualties.

As shown in FIG. 2, the revetment structure constructed by the rock according to the prior art is a natural stone so as to protect the soil surface 1 evenly after stopping the soil surface 1 using heavy equipment or the like. (2) Laminate is formed by connecting the anchor core 3 (generally, 8 mm in diameter) to (usually, 300 mm in diameter).

The pressure plate 4 is connected to one end of the iron core 3 described above, and the adhesive is attached to the iron core 3 coupled to the fixing hole 5 and the fixing hole 5 drilled in the natural stone 2 by a drill machine. After each application, the iron core 3 is fixed to the natural stone 2.

The natural stone 2 is filled with rubble 5 having a relatively small size between the natural stone 2 and the pressure plate 3 so as to prevent the natural stone 2 from being separated from the stacked position.

Therefore, the natural stone 2 can be prevented from flowing down from the above-mentioned earth and sand surface 1, so that the earth and sand surface 1 can be protected from feng shui.

6 in the figure is a filter mat.

In the above-described shoreline structure, the adhesive for fixing the natural stone (2) to the anchor iron core (3) must be cured to start the next step of work, it takes a lot of work time, leading to a rise in labor costs, the iron core (3) Easily relaxed from the fixing hole (5) to work because of the re-establishment has a problem that the overall construction cost is increased.

In addition, since there is no binding force between the natural stones (2), the resistance to the flow rate is weak, and the natural stone (2) is filled with rubble or concrete to fill the voids of the natural stone (2) to have a resistance to the flow rate, so the flow rate at the inflow of river water There is a problem that can not attenuate the damage caused by the reflection action of the flow rate.

As such, because the flow rate does not attenuate and causes scour, the natural stone 2 easily collapses due to the flow rate and earth pressure during flooding, and the aggregates are lost to collapse the dike, resulting in a large flood accident.

In addition, due to the rubble filled in the pores between the natural stone (2), such as plants and plants do not inhabit, causing water pollution, raising the temperature around the river bank, and has a problem of increasing the environmental pollution source in the atmosphere.

It is an object of the present invention to provide a flow rate damping type relief structure using a cramp that has a resistance to the flow rate to increase the durability by integrally connecting the rock and the rock as a connecting member.

Another object of the present invention is to prevent the loss of aggregate, stream clavicle and erosion by attenuating the flow rate of the fluid by securing the water inflow space in the gap between the rock and the rock installed in the position in contact with the river water It is to provide a flow rate damping type relief structure using a clamp.

Another object of the present invention is to provide a habitat, such as animals, trees or plants in the air gap between the rocks to reduce the air pollution or water pollution source to provide a comfortable urban environment to reduce the flow rate decay-type revetment To provide.

Still another object of the present invention is to provide a flow rate damping type relief structure using a clamp that can be applied to natural stone as well as concrete relief block when constructing a relief structure.

Still another object of the present invention is to provide a flow rate damping type relief structure using a bracket so as to prevent the connecting member for integrally connecting the rock and the rock to escape from the fixed hole of the rock.
