Description

STONE NET AND CONSTRUCTION METHOD USING THE SAME}

The present invention relates to a stone net.

In recent years, the use of land in the river basin has increased and urbanization has significantly changed the river environment.This change in river environment is further accelerated due to the large-scale civil engineering works for watershed and completion. The unique natural environment has its own trend. In addition, such changes in the river environment have caused water pollution, resulting in a decrease in the habitat density and diversity of river fauna and flora.

In urban rivers with high density of land use around rivers, the river environment was changed due to the maintenance of reservoirs and blunts, the linear repair of waterways, and the construction of river banks for the purpose of flood communication. However, the concrete revetment block physically blocks the infiltration of river water into the soil layer, which not only regenerates the wetland vegetation of natural rivers, but also changes the water temperature due to the disappearance of the shade provided by the celestial vegetation. In other words, it loses its function as a spawning ground and damages the habitats of birds that feed around riverside vegetation and hide in vegetation bushes.

The natural stone has a first coupling hole formed on one side and a second coupling hole formed on the other side,
The coupling member
A first coupling leg of which one side is inserted and coupled to the first coupling hole;
A support leg, one end of which is bent and extended from the other side of the first coupling leg;
A second coupling leg bent at the other end of the support leg and inserted into the second coupling hole; And
And a coupling unit for coupling said support leg to said support net. The method of claim 1,
And a sidewall net coupled to a third side of the support net, one side end of the first sidewall net and one side end of the second sidewall net, and having a plurality of net holes provided therein. . delete delete The method of claim 1,
The first coupling leg is
A first coupling curved portion that is convex toward the inner one side of the first coupling hole and is formed in a curved shape so as to be in contact with the inner one side of the first coupling hole; And
Extends from the first coupling curve, is convex toward the inner side of the first coupling hole opposite to the inner side of the first coupling hole, and is formed in a curved shape to be in contact with the inner side of the first coupling hole; A second joining curve portion,
The second coupling leg
A third coupling curved portion that is convex toward the inner one side surface of the second coupling hole and is formed in a curved shape so as to contact the inner side surface of the second coupling hole; And
Extends from the third coupling curve, is convex toward the inner other side of the second coupling hole opposite to the inner side of the second coupling hole, and is formed in a curved shape to be in contact with the inner other side of the second coupling hole; A stone net, characterized in that it comprises a fourth coupling curve portion. delete delete delete delete delete delete
