Basement roof drainage system

Abstract

The invention discloses a basement roof drainage system, and belongs to the field of drainage system structural designs. The basement roof drainage system comprises a ceramsite net ditch, porous bricks and a water collection ditch, wherein ceramsites are wrapped in nonwoven cloth of the ceramsite net ditch; the porous bricks are built on the two sides of the ceramsite net ditch; the water collection ditch is arranged on the periphery of a basement roof. The water collection ditch is communicated with a catch basin through a drainage pipe and arranged on the inner edge of the basement roof area. In this way, the problems that a drainage system in the prior art is low in drainage efficiency, so that the survival rate of plants is low are solved, and the problems that the drainage system in the prior art will make rainwater enter an earthwork backfilling weakness area, so that differential settlement of green space is obvious are also solved. In this way, not only is cost lowered, but also the load on the basement roof can be relieved; meanwhile, soil on the basement roof can keep proper moisture content, breathability is enhanced, and the growth of the green plants on the basement roof is further facilitated.

Description

technical field [0001] The invention relates to a drainage system, in particular to a basement roof drainage system. Background technique [0002] With the development of society and the continuous improvement of people's living standards, the number of family cars is increasing rapidly. In order to solve the problem of parking difficulties, underground garages are generally established. At the same time, in order to improve people's living environment, most of the underground garages use horizontal planting roofs and When planting plants, when there is a lot of rain and the area of ​​the single roof of the underground garage is large, the rainwater on the planting roof will not drain smoothly. root phenomenon. [0003] For this reason, builders often use the method of finding slopes in the design of building structures to solve the drainage problem of flat planting roofs to overcome the phenomenon of plant rotten roots. However, due to the large area of ​​the top surface o...

AI Technical Summary

Problems solved by technology

[0006] In view of the above existing problems, the present invention provides a basement roof drainage system to overcome the problem of low drainage efficiency of the drainage system in the prior art, which leads to low plant survival rate, and also overcomes the problem that the drainage system in the prior art will make rainwater Entering the soft underbelly area of ​​earthwork backfill will lead to the obvious problem of uneven settlement of the green space, thereby not only reducing the cost, but also reducing the load on the roof of the basement. Conducive to the growth of green plants on the roof of the basement
