Novel composite drainage and seepage pipe with physical blockage resisting function

Abstract

The invention discloses a novel composite drainage and seepage pipe with a physical blockage resisting function. The novel composite drainage and seepage pipe comprises a drainage and seepage pipe body with a cylindrical main body, a plurality of water seepage outer grooves are uniformly distributed on the periphery of the drainage and seepage pipe body in an annular array, water seepage structures communicating with the inner wall of the drainage and seepage pipe body are arranged at the bottoms of the water seepage outer grooves, geotechnical cloth is wrapped around the outer wall of the drainage and seepage pipe body and the inner walls of the water seepage outer grooves, a sand gravel filter material fills the water seepage outer grooves, and a protection layer wraps the outside of thedrainage and seepage pipe body. According to the novel composite drainage and seepage pipe, the sand gravel filter material and the geotechnical cloth are combined together for use to mutually complement superiority, wherein the sand gravel filter material is utilized to resist physical blockage, and the geotechnical cloth is utilized to block fine particles in soil, so that the risk of the physical blockage of the geotechnical cloth is reduced, and the overall water drainage capacity of the drainage and seepage pipe is improved.

Description

technical field [0001] The invention belongs to the technical field of engineering seepage drainage, and in particular relates to a novel composite seepage drainage pipe resistant to physical clogging. Background technique [0002] Engineering drainage is involved in tailings dams, retaining walls, embankments, roadbeds, tunnels and other projects. The use of drainage facilities can discharge excess water in the project and reduce the water pressure in the project to ensure the stable and safe operation of the project. Once the drainage facilities fail, the water pressure in the project will rise, affecting the stability of the project, and in severe cases, it will lead to project damage and cause loss of people's lives and property. Engineering drainage requires a reverse filter layer. As a traditional reverse filter layer, sand and gravel have excellent performance in engineering drainage. However, due to the strict requirements on particle size and gradation when using ...
