Description

Technical Field

[0001] The utility model belongs to the technical field of green buildings, and in particular relates to a siphon drainage structure for a planting top plate of an underground garage. Background Art

[0002] The zero-slope drainage system of the garage roof is a drainage system formed by scientifically and reasonably laying water pipes, pipe fittings, exhaust pipes and other devices in the drainage area of ​​the garage roof, so that there is no need to set a material slope layer on the roof. It can not only quickly remove excess infiltrated rainwater in the roof covering and protect the normal growth of plant roots, but also avoid water accumulation on the covering surface, absorb and regulate rainwater surface runoff, and solve the problems of low blind ditch drainage efficiency, roof water stagnation and surface water accumulation, and avoid leakage due to long-term poor drainage of the basement roof and accumulated water.

[0003] However, during the construction of the existing garage roof zero-slope drainage system, a macromolecular special-shaped drainage board is generally laid on the basement roof after leveling and slope to form an overhead layer, and the water is discharged by using structures such as siphon drainage grooves, thereby achieving the waterproofing and drainage of the garage roof planting roof. However, when the underground garage planting roof siphon drainage structure as described above is used, there are still problems such as: the existing garage roof zero-slope drainage system generally uses geotextile as the main anti-seepage component, which is laid on the basement roof for anti-seepage, but due to the poor self-adhesive effect of the geotextile, it is often easy to leak at some overlapping nodes during use; at the same time, when the existing garage roof zero-slope drainage system is sealed at the edges such as the inner corners, the outer corners, the middle and the top of the vertical drainage board, only bonding and hot melting are used to connect to ensure that the drainage board does not fall off, but the deformation of the drainage board at the deformation structure and the entry of external dust into the internal channel of the drainage board are ignored, which easily causes the internal channel of the drainage board to be blocked, and it is easy to cause water stagnation on the roof and water accumulation on the surface during use.

[0004] Based on this, the utility model designs a siphon drainage structure for a planting top plate of an underground garage to solve the problems existing in the above-mentioned prior art. Utility Model Content
