Description

A structure of anti-wave wall for reducing wave climbing

technical field

The utility model belongs to the technical field of construction of flood control earth embankments and earth-rock dams in water conservancy and hydropower projects, in particular to a wave-proof wall structure for reducing wave climbing, and is particularly suitable for the crest structures of earth embankments and earth-rock dams.

Background technique

In water conservancy and hydropower projects, the anti-wave wall is a wall set at the front of the dam crest to prevent waves from crossing the dam crest. It is mostly used on reservoirs, rivers, and dams to prevent waves, floods, and water. When the water surface is relatively open, the length of the wind area is long, and the wind speed is high, such as plains or seaside areas, the upstream dam slope of the earth-rock dam and earth embankment is relatively gentle, and the wave climbs high, resulting in a corresponding increase in the crest elevation. , and the filling volume of the dam body is relatively large. In order to overcome the above-mentioned problems, at present, vertical anti-wave walls, anti-arc wave-spout anti-wave walls, deep arc anti-wave walls, etc. are usually installed upstream; The original design of the wave wall top elevation is low, or after years of settlement and deformation, there is a danger of waves overtaking the top of the wave wall. Reinforcement treatment is required. The existing technology is to increase the wave wall or dam crest elevation.

In practical application, the existing wave wall structure mainly has the following deficiencies:

(1) For the wave wall whose upstream is a straight wall, it cannot effectively reduce the wave climb;

(2) For the existing anti-arc wave-spout anti-wave wall structure is located on the top of the anti-wave wall, in the safe super-elevation area, not in the wave climbing area, and cannot really play the role of wave-guiding wave;

(3) There are construction difficulties for the deep arc-shaped wave wall structure, and it is difficult to apply to the high wave wall structure, and it is not suitable for the aforementioned reinforcement treatment of the wave wall.

Therefore, the existing wave wall structure is not ideal enough, either to reduce the wave climbing effect is poor, or the scope of application is narrow, and the construction cost is high.

The structure can effectively reduce the wave climbing, thereby lowering the elevation of the dam crest to achieve the purpose of saving investment, and also provides a risk-relief reinforcement measure for the built dams and embankments due to the low elevation of the wave-resistant wall top.
