Planting surface waterproof system

Abstract

The invention discloses a planting surface waterproof system, and belongs to the field of building waterproofing. The problem that leakage can easily happen when a waterproof coiled material bears heavy pressure is solved. By means of the scheme, the planting surface waterproof system comprises a planting soil layer, a filtering layer, a drainage layer, a slope forming layer, a waterproof coiled material and a reinforced concrete structural layer from top to bottom. The drainage layer comprises drainage pipelines distributed at intervals and broken stone with which the spaces between the drainage pipelines are filled. The drainage pipelines comprise a first semicircular pipe and a second semicircular pipe. The diameter of the first semicircular pipe is smaller than that of the second semicircular pipe. The first semicircular pipe is located above the second semicircular pipe, and openings of the first semicircular pipe are opposite to openings of the second semicircular pipe. Water leaking holes are formed in the first semicircular pipe. A gap is formed between the outer wall of the first semicircular wall and the outer wall of the second semicircular wall and sealed through a steel wire net. The steel wire net is covered with a water-permeable fabric. The first semicircular pipe, the second semicircular pipe and the steel wire net form a closed loop cavity. One end of the second semicircular pipe is sealed, and the other end of the second semicircular pipe is provided with a drainage opening. Most of water is discharged out of the second pipeline, the erosion of the waterproof coiled material by pressure water is reduced, and the leakage probability is reduced.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to a planting surface waterproofing system. Background technique [0002] Nowadays, with people's further pursuit of quality of life, people often plant flowers and plants on the roof or indoors. On the one hand, they can cultivate their sentiments, and on the other hand, the air environment will also be improved. [0003] However, planting on the roof or indoors requires the planting surface to have good waterproof ability, otherwise it will affect the quality of the house. [0004] The current planting surface is generally equipped with drainage pipes, and the rainwater is collected and discharged through the drainage pipes, thereby reducing the burden on the waterproofing membrane on the planting surface, and can also reduce the thickness of the waterproofing membrane. At present, the structure of the drainage pipe is generally provided with a seepage hole on the surface, a...

AI Technical Summary

Problems solved by technology

Due to the small water seepage in this way, the rainwater is easy to flow directly to the waterproof membrane along the drainage pipe, and the waterproof membrane bears heavy pressure (water pressure) and is prone to leakage
