Abstract

The invention discloses a ribbed waterproof and water-draining coiled material and a construction method thereof. The ribbed waterproof and water-draining coiled material comprises a waterproof layer,a supporting layer and a water-draining layer, wherein the supporting layer is positioned between the waterproof layer and the water-draining layer; and the waterproof layer, the supporting layer andthe water-draining layer are connected integrally. The waterproof layer, the supporting layer and the water-draining layer are simultaneously arranged on the ribbed waterproof and water-draining coiled material, so that the ribbed waterproof and water-draining coiled material simultaneously has functions of improving foundation or roadbed carrying ability, obstructing underground water and solving the problem of water drainage of a foundation or a roadbed, then uneven sedimentation of the pavement of the foundation and roadbed is reduced, reflection cracks between structure layers of the pavement of the foundation and roadbed are prevented, the stability of the integral structure of the foundation and roadbed is improved, and the service lives of a building structure and a road are prolonged.

Description

Technical field [0001] The invention relates to the technical field of civil engineering, in particular to a reinforced drainage water-insulating coil and a construction method thereof. Background technique [0002] At present, materials such as geomembrane, geotextile and geogrid (chamber) have been widely used in the field of civil engineering technology, which can well improve the physical and physical properties, water resistance and drainage performance of foundations, roadbeds and pavements. However, simple The application of geomembrane, geotextile and geogrid (chamber) can only play its own role alone, or improve the bearing capacity of the foundation or roadbed, or block groundwater, or discharge the surface and part of the internal water, but not at the same time. The load-bearing capacity of the foundation or roadbed also serves to block groundwater and solve the drainage problem of the foundation or roadbed. Summary of the invention [0003] The main purpose of the pr...
