City river antiseepage structure and construction method

Abstract

The invention belongs to the water conservancy engineering field, and especially relates to a city river antiseepage structure and a construction method; the city river antiseepage structure comprises a river slope antiseepage structure and a river bottom antiseepage structure; the river slope antiseepage structure comprises a base layer, a viscosity soil layer and an articulated slope protection brick layer arranged on the river slope from bottom to top; the river bottom antiseepage structure employs a concrete structure or a swelling waterproof blanket; the swelling waterproof blanket comprises a base layer, an impervious layer and a protective layer arranged on the river bottom from bottom to top; the viscosity soil layer is bigger than 30cm in thickness, the viscosity granule content is 20-30%, and the maximum particle size is 5cm; the beneficial effects are that the multi-layer composite antiseepage structure enables the riverbed to have strong anti-impact ability, thus solving the problems that an existing antiseepage structure cannot satisfy antiseepage demands under dynamic water conditions, and providing the solution for river antiseepage and flood prevention multifunctional demands; the city river antiseepage structure and the construction method are convenient in construction.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and in particular relates to an anti-seepage structure and a construction method for urban river courses. Background technique [0002] With the continuous development of modern cities, people's requirements for the quality of the city are getting higher and higher. Greening and water systems are becoming more and more the key to improving the quality of the city. For cities with relatively short water resources, the use of urban rivers to build landscape Lakes and landscape reservoirs have become an integral part of urban development. Therefore, when urban rivers are treated, it is often necessary to carry out anti-seepage treatment under the prerequisite of flood discharge. In this way, it is necessary to choose an anti-seepage structure with strong adaptability to deformation, good anti-seepage effect, and strong erosion resistance under the condition of urban river flow.

Problems solved by technology

At present, the anti-seepage structures of urban rivers that are widely used are: concrete slab anti-seepage and clay anti-seepage. The impact is prone to cracks, and at the same time, the water body is completely isolated from the groundwater body due to the concrete slab, which is not conducive to ecological exchange

Clay anti-seepage not only has a large amount of earthwork, which makes the anti-seepage of revetment difficult to deal with, but also the clay is easy to lose in the state of flowing water. For cities, the cost of finding high-quality clay is also quite high
