Novel-structure composite waterproof and drainage special-shaped sheet for planted roof and construction process thereof

Abstract

The invention provides a novel-structure composite waterproof and drainage special-shaped sheet for a planted roof and a construction process thereof. The novel-structure composite waterproof and drainage special-shaped sheet for the planted roof comprises a water filtering layer and a waterproof and drainage layer, wherein the waterproof and drainage layer is arranged under the water filtering layer and comprises a waterproof geomembrane; the upper surface, corresponding to the water filtering layer, of the waterproof geomembrane is provided with a plurality of projected casings; spaces among the projected casings form a drainage passage; and at least one edge of the waterproof geomembrane outwards extends out of a lap joint edge. The novel-structure composite waterproof and drainage special-shaped sheet provided by the invention has the advantages that the toughness is good; the tearing resistance and the puncture resistance are realized; the engineering manufacturing cost is reduced; the same-layer drainage design is used, so that the water filtering, the water drainage and the waterproof performance are compounded into a whole; the integration of first drainage and then prevention and waterproof and drainage is really realized; the leakage is thoroughly avoided; and the zero-slope organized drainage is realized.

Description

technical field [0001] The invention relates to the technical field of building waterproofing and drainage, in particular to a waterproofing and drainage structure, in particular to a novel structure composite waterproofing and drainage heterogeneous sheet for planting roofs and its construction technology. Background technique [0002] The roof of the building is one of the main enclosure surfaces of the building. As an effective energy-saving and environmental protection measure, the roof greening has attracted more and more attention. Planting the roof is to green the roof, especially the planting roof on the basement roof has attracted more and more attention. First, the basement is widely used to park vehicles. Second, building a roof garden can beautify the environment and purify the air to enrich the urban landscape. The planting roof is to spread planting soil on the waterproof layer of the roof of the building and the roof of the underground project, and plant plant...

AI Technical Summary

Problems solved by technology

Nowadays, the roof area of ​​planted roofs is generally large, and it is difficult to find slopes in traditional methods, and the waterproof and drainage effects are difficult to guarantee. Later property management is a difficult problem
