Multi-layer compound three-dimensional waterproof drainage network

Abstract

Provided is a multi-layer compound three-dimensional waterproof drainage network. A body is of a layered structure and comprises a geonet, a geofabric and a compound geomembrane. The compound geomembrane and the geofabric adhere to the top and the bottom of the geonet respectively. The compound geomembrane is formed by two geofabric layers and a geomembrane layer. The two geofabric layers are located on the upper side and the lower side of the geomembrane layer respectively. The geofabric and the compound geomembrane with the two geofabric layers and the geomembrane layer adhere to the two sides of the three-dimensional geonet to form the multi-layer compound three-dimensional waterproof drainage network, and the multi-layer compound three-dimensional waterproof drainage network is high in waterproof drainage capability and can bear a long-term high-pressure load; the multi-layer compound three-dimensional waterproof drainage network is very high in tensile strength and shear strength, the probability of geofabric embedding in a net core is reduced, the long-term stable water-guiding and waterproof effects can be achieved; the anti-pressure capability of the multi-layer compound three-dimensional waterproof drainage network is far larger than that of an ordinary drainage network, the water prevention and drainage are integrated, the cost is greatly reduced, and secondary construction is avoided.

Description

technical field [0001] The invention relates to the technical field of drainage materials, in particular to a multilayer composite three-dimensional waterproof and drainage net. Background technique [0002] In the field of infrastructure construction, water filtration and drainage are unavoidable problems, such as landfills, roadbed and road surface waterproof drainage, railway waterproof drainage, tunnel waterproof drainage, underground structure waterproof drainage, retaining wall back waterproof drainage, building The waterproof and drainage of roof gardens must take good water filtration and drainage measures, but the current drainage network, due to its own defects in the skeleton, has low tensile strength and shear strength, cannot withstand long-term high-pressure loads, and has poor drainage and waterproof capabilities. , often resulting in more silting.
