Description

Revetment construction method which is made of diamond pattern net}

The present invention relates to a raft construction method using a ridge net that can prevent the loss of soil in the river, the vegetation can be planted.

In order to prevent the loss and collapse of the surface due to flooding, the conventional rafts have been constructed by installing nonwoven fabrics on the surface of river slopes or roadside cutouts and installing a raft block on the top thereof. Conventional revetment block (1) constructed as shown in Figure 1b is a dimensional function to protect the ground surface and prevent the outflow of soil by withstanding the water pressure or flow rate of the river water, but a wide range where the flow rate is strong It can not be applied, and the upper part of the block (1) is not possible to install the natural friendly block because the vegetation is impossible.

In order to solve the above problems, the present inventors have applied for a number of patents, such as Patent No. 1999-0016157 and Patent No. 1999-0038443. The patent No. 1999-0016157 by installing a block for preventing vegetation and soil outflow to simultaneously perform the dimensional function and vegetation function. It prevents the loss of soil and maintains the shape of the block body in the event of a fire or subsidence, so that the auxiliary body can be replaced and repaired for easy maintenance. In this case, only the herbaceous vegetation is possible in this case, the vegetation of the woody plant is impossible and will be restricted by the city plant. In addition, Patent No. 1999-0038443 has a possibility that the existing revetment block may be pushed along the inclined surface due to the pressure of the soil, and because a plurality of blocks are combined in series, the material cost is high and a lot of construction time is required, thereby reducing workability. In order to solve the problems, such as gabions and earth bricks to construct a river and to make a revetment, but also using a lot of stones to construct because of excessive construction costs, there is a gap between the stones and the vegetation is impossible There is a problem.

The rafting method using the ridge net of the present invention devised to solve the above problems is to provide a natural environment by using the upper, lower ridge net and vegetation bag instead of the conventional raft block made of concrete, ridge to prevent soil loss The purpose is to provide a revetment method using a network.

In addition, the rafting method using the ridge network of the present invention is to provide a rafting method using a ridge net easy to construct a stable raft structure that can withstand strong flow rate by integrating the upper and lower ridge network.
