Description

Technical Field

[0001] The utility model relates to the technical field of cutoff walls, in particular to a cutoff wall for water conservancy and hydropower projects. Background Technique

[0002] A cutoff wall is a continuous underground wall built in loose pervious layers or earth-rock dams to play a role in seepage prevention. Due to its reliable structure, good seepage prevention effect, adaptability to various stratum conditions, simple construction and low cost, etc., especially in dealing with potential problems of seepage deformation such as dam foundation leakage, soil piping behind the dam, etc., it has been widely used at home and abroad. For the seepage prevention treatment of water conservancy and hydropower overburden layers and earth-rock cofferdams in China with seepage prevention pressure, a cutoff wall is generally the first choice.

[0003] Patent Publication No.: CN216765771U. The utility model discloses an environment-friendly cutoff wall for water conservancy projects, which relates to the technical field of water conservancy projects, and improves the problem that most of the existing cutoff walls for water conservancy projects are made of concrete and are prone to water seepage after being subjected to the impact pressure of water, thus easily reducing the practicability of the cutoff wall for water conservancy projects. It includes a dam body, and a high-strength concrete layer is arranged on the inclined surface inside the dam body; two cutoff walls are fixedly installed inside the dam body, a gap is formed between the two cutoff walls, a buffer layer is arranged inside the gap, and protective layers are arranged on the outer sides of the two cutoff walls. Through the setting of the two cutoff walls in this application, a double-layer water isolation structure is formed. When one of the cutoff walls cracks, the other cutoff wall can continue to provide effective protection. Moreover, due to the setting of the buffer layer, when the cutoff wall is impacted, the buffer layer can effectively buffer and it is not easy for the cutoff wall to crack.
