Description

Ecological mud-blocking wall structure in lake water environment treatment

Technical Field

The utility model relates to an ecological mud-blocking wall structure in lake water environment treatment.

Background

In natural water system, the lake has various functions of regulating river runoff, improving water quality, providing habitat for animals, regulating local climate, providing drinking water and food for human beings, protecting and restoring the lake water environment, and has important significance for improving regional ecology and regional water safety.

In the lake water environment treatment engineering, in order to increase the depth of the lake water body, enlarge the storage capacity of the lake, reduce the eutrophication of the water body and protect the biological diversity, people often adopt a mode of dredging the bottom of the lake or heightening the dyke to achieve the aim, but the mode is not widely adopted at present because the project place is usually free from the problems that a natural spoil field is used for absorbing the silt, the environment is easy to pollute in the silt external operation process, the soil cannot be cultivated and the like. Therefore, in order to reduce environmental pollution, save engineering investment and reduce occupied cultivated land, sludge is adopted for on-site digestion, and a mode of forming a beach or an island by blowing and filling the sludge is preferably adopted.

In the traditional beach or island construction engineering, people generally adopt the mode of arranging a concrete retaining wall to form a blocking ridge or driving a tubular pile into water to form a wall to block the soil, but long-term practice shows that the hard cofferdam cuts off the ecological connection between water and the soil of a bank slope, is not easy to cover green and is not in accordance with the development of the ecological environment protection concept, so the hard cofferdam has been gradually eliminated. Along with the importance of ecological environment, the ecological mud-stopping wall gradually becomes the primary choice of beach restoration or island construction, and the technical key point is that under the condition that lake water drainage is not needed, the characteristics of internal and external pressure balance of the mud-stopping wall are utilized, local materials are utilized to form a self-stabilizing mud-stopping ridge, and compared with a hard mud-stopping wall, the ecological mud-stopping wall has the advantages of enriching ecology and reinforcing water body and soil environment communication.

However, due to poor lake geological conditions and thicker sludge blowing-in, the traditional ecological sludge blocking wall is difficult to form a stable structure, cannot prevent the sludge from sliding, and cannot meet the requirements of rapid dehydration and secondary pollution reduction of the sludge, so that technological innovation on the ecological sludge blocking wall is required.
