Root-resistant modified bitumen waterproof structure for planting roof

Abstract

The invention provides a root-resistant modified bitumen waterproof structure for a planting roof. The waterproof structure includes a structural layer, a slope making layer, a heat preservation layer, a leveling layer, a root-resistant waterproof layer, a drainage layer and a filter layer, which are arranged from bottom to top; the root-resistant waterproof layer is made of modified bitumen waterproof rolling material; the modified bitumen waterproof rolling material is composite copper base modified bitumen waterproof rolling material or chemically root resistant type modified bitumen waterproof rolling material. The root-resistant modified bitumen waterproof structure for the planting roof, provided by the invention, has the dual functions of resisting water and preventing root penetration of the plant and the advantages of being root-resistant, tear-resistant, high in tensile strength and ductility, high in capability of adapting to base layer shrinkage strain and crack, and good in high and low temperature resistance, corrosion resistance, mildew resistance and weather resistance.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, in particular to a root puncture-resistant modified asphalt waterproof structure for planting roofs. Background technique [0002] With the acceleration of urbanization in my country, the construction area has increased sharply, urban green space has been continuously reduced, and at the same time, the gases released by various energy consumption and vehicle exhaust have continued to increase, the "heat island" effect has become more serious, and the urban ecological environment has deteriorated day by day. One of the effective ways to alleviate the above contradictions is to develop planting roofs. The planted roof can protect the roof surface and reduce ultraviolet rays. However, the plant roots in the planted roof system are extremely penetrating. If the waterproof material is not selected properly, the plant roots will penetrate and cause building leakage. Moreover, when leakage...

AI Technical Summary

Problems solved by technology

The planted roof can protect the roof surface and reduce ultraviolet rays, but the plant roots in the planted roof system have strong penetrability. If the waterproof material is not selected properly, the plant roots will penetrate and cause building leakage.

Moreover, when leakage occurs, it is difficult to determine the exact location where the waterproof material is damaged, and the workload of renovation is large, which will cause great economic losses

In addition, if the root system of the plant penetrates into the structural layer of the roof protrusion, it will endanger the safety of the building to a certain extent.
