Abstract

The present invention builds a zigzag retaining wall in the ground on both slopes, which is the legal face of the river, and protrudes and installs a central bulkhead at a predetermined height in the middle of the river in the direction of the river. It is to devise to be quietly induced and to prevent soil scour and loss of river slope by rapids during flooding.

Description

The median wall of rivers and the collapse prevention facilities of hill}

The present invention makes both eyes of the river into relatively large uneven surface, and builds a zigzag-shaped retaining wall so that both eyes are not collapsed by the rapids that flow while bending to the left and right during flooding. It is designed to keep the flow of running water stable by protruding the central bulkhead in the direction. Conventionally, both rivers prepare for flooding in addition to the degree of covering the sandstone or gabion, or laying a separately formed covering block. There was no other river structure.

Therefore, during flooding, a large amount of water flows down and flows by scouring down the slopes of both rivers.In particular, the curvature point where the river is bent causes more soil collapse, loss, and flow in a rapid rapid flow. This leads to the collapse of the banks, dams, and so on, resulting in enormous damage such as loss of farmland and flooding. In addition, the flow rate is very fast and the water loss is not constant according to the curved topography due to the straight steel construction such that the river flows linearly according to the surrounding environment and the purpose of development.

The present invention prevents soil loss in both streams as much as possible by preventing the flow rate of the rapid flow to minimize the damage caused during the flooding in the conventional rivers as described above, and the flow of water is severely curved According to the shape of the bottom, it is designed to artificially guide the flow direction of the flowing water stably by providing a central bulkhead at the center of the lower bed in a state of bending to the left and right, according to the accompanying drawings. Same as

As shown schematically in FIG. 1, the unit vertical retaining wall 2, which is a circular arc surface of a constant radius of concrete or the like, is embedded in the middle of the inclined surface 1 of both sides of the river R, which is implemented according to the present invention. The unit vertical retaining wall (2) is embedded in the direction of the river length in a zigzag form to deviate from each other, but the height difference between the upper and lower sides of each unit vertical retaining wall (2) is equal to the inclination angle of the river binocular slope (1). The height difference can be an angle, and even in the middle of the riverbed (3) in the middle of the river, the concrete protrudes the central bulkhead (4) of a predetermined height and thickness, and the sides of the central bulkhead (4) are arcuate recesses (5) (5a). Formed to form a structure of the present invention by allowing the flow of flowing water more flexibly.

The rivers implemented according to the present invention constituted as described above have a flat bottom and both sides are arcuate recessed surfaces (5) (5a) at the center of the bottom, so that the flowing water does not flow to the left and right and is guided flexibly. Even when the rapid hits the river slope, the concrete unit vertical retaining walls (2) are embedded to prevent erosion by blocking the soil scrubbing at any line, and the vertical retaining walls (2) are zigzag-circular arcs, Since it is resisted while hitting the vertical retaining wall (2) to reduce the flow rate it is possible to more effectively prevent soil scour, loss of both rivers.

Claims (1)

In a river in which both eyes of the river are inclined surfaces (1), a unit vertical retaining wall (2) which is a circular arc surface of a constant radius made of concrete or the like is embedded in the middle of the binocular slope (1), and the arc of the unit vertical retaining wall (2) is provided. In the direction of the length of the river in the direction of the zigzag connected to each other in a zigzag way, the height difference between the vertical and vertical retaining walls (2) is the difference in height that can be the same angle as the inclination angle of both sides of the river (1). In the middle of the riverbed (3), the river is characterized in that the concrete projecting the central bulkhead (4) having a predetermined height and thickness with concrete, and forming both sides of the central bulkhead (4) as arc recesses (5) (5a). Central partition and binocular collapse prevention facility.
