It's about structure.

Generally, slope protection facilities are installed in cutouts, rivers, and levees for road opening to prevent artificially cut slopes. These slope protection facilities are commonly referred to as retaining walls. It is often used to use land efficiently in high areas.

Retaining walls are used to build up soil, cut down mountains, or fill up the shore.In order to prevent the collapse of soil, retaining walls are formed to form vertical or stepped wall walls made of stone, steel, or concrete, etc. It is generally constructed to protect loads and to resist loads of rock or soil that form slopes.

Among these, the retaining wall installed on the bank embankment prevents water from flowing out of the stream and facilitates the flow of flowing water, which separates rivers, lakes, and seas from land for the purpose of preventing floods or water storage. Constructed in front of the embankment.

However, in the case of the retaining wall installed on the river embankment 1 as described above, when the natural disaster such as flooding occurs, the earth and sand of the bottom 100 of the retaining wall foundation 12 are lost due to the rapid flow rate. Due to the scour phenomenon there is a problem that the retaining wall 10 is conductive or collapsed. The collapse of the river retaining wall leads to the collapse of the secondary embankment, which causes large flood damage, requiring new measures to prevent the collapse of the retaining wall.

The present invention is to solve the above-mentioned problems, by installing a structure for preventing scour at the bottom of the river retaining wall to prevent scour in advance, to prevent the collapse of the retaining wall due to scour and damage caused by large flood The purpose is to provide a river retaining wall based scour prevention structure.

In order to achieve the above object, the present invention, in the scour prevention structure is installed in the bottom surface of the river retaining wall foundation and the bottom of the river, disposed in the longitudinal direction along the flow path of the river, one end is a hollow hollow The other end of the hollow tube is opened through the injection hole so that concrete can be injected therein, and the injection hole is a plurality of rod blocks that can be opened or closed through a stopper, and a plurality of rod-shaped pipes connected to each other and at the same time adjacent to each other. Consists of the connector so that they do not push in the longitudinal direction, the plurality of rod-shaped pipes are connected via the connector as a concrete therein to prevent the scour at the bottom of the retaining wall foundation and the bottom of the river It provides a river retaining wall foundation scour prevention structure, characterized in that.

Here, the spigot block is made of a reinforced plastic material, when another spigot block is stacked thereon to be interviewed with each other to minimize the gap between them to have a flat rectangular cross-section to the top and bottom surfaces to achieve a safe laminated structure It would be nice.

In addition, the connector applied to the present invention will be better to adopt a cross-type binding anchor so as not to be pushed in the longitudinal direction while the interlocking block between the blocks.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view for showing the construction state of the river retaining wall foundation scour prevention structure according to the present invention.

As shown in Figure 2, in the river scour prevention structure according to the present invention, a plurality of spigot block 20 is disposed in the longitudinal direction along the flow path of the river on the bottom surface of the river retaining wall foundation 12, such The block 20 is filled with a stuffing material such as concrete to have a weight enough to resist the flow rate to form a structure that can prevent scour caused by river water.

Figure 3 is an exploded perspective view for showing the fastening state between each component of the river retaining wall foundation scour prevention structure according to the present invention.

Looking more specifically with reference to Figure 3, the spigot block 20 is a hollow hollow tube with one end closed structure so that the other end is injected through the inlet 22 so that the filling material such as concrete can be injected therein Is made of, the inlet 22 is made of a configuration that can be opened or closed through the stopper 24.

Such hemp block 20 is made of a material, such as fiberglass reinforced plastic (FRP), which can prevent scouring of the bottom surface of the retaining wall foundation without corrosion in the river.

In addition, the spigot block 20 has a rectangular cross-section with a flat upper and lower surfaces so as to be interviewed with each other when stacked on the spigot block to minimize the gap therebetween and form a safe laminated structure. And it can be firmly installed on the river floor through the concrete filling material therein, one or more reinforcing ribs (not shown) may be integrally formed therein to reinforce its strength.
