Drainage system inside corner structure

Abstract

The invention discloses a drainage system inside corner structure. The drainage system inside corner structure comprises a concrete base body, waterproof layers, polymer special-shaped sheets and geotextile, wherein the ground and the vertical face at an inside corner of the reinforced concrete base body are painted with the waterproof layers; the polymer special-shaped sheets are laid on the ground and the vertical faces of the waterproof layers, and the outside of the polymer special-shaped sheets is covered with the geotextile; and the plurality of polymer special-shaped sheets are arranged, and are overlapped with one another at the corner angle of the inside corner, and the lap joint of the polymer special-shaped sheets adopts a first double-sided self-adhesive waterproofing membraneto be bonded together. According to the drainage system inside corner structure, the double-sided self-adhesive waterproofing membrane is adopted as an additional layer at the inside corner of the structure so that the polymer special-shaped sheets can be effectively sealed and fixed together, influent seepage is blocked from entering a structural layer, and the effect of "anti-drainage combination" is achieved.

Description

technical field [0001] The invention belongs to the technical field of drainage, in particular to a drainage system internal corner structure. Background technique [0002] Large-scale basement planting roofs sometimes form stagnant water due to precipitation. When the accumulated water rises to a certain height and submerges the plant root system, it may cause root rot. Therefore, it is very necessary to set up a drainage layer. The drainage layer is used in conjunction with the blind ditch, which can make the structure simple and does not reduce the planting area of ​​plants. However, the traditional blind ditch drainage has limitations, local drainage is not smooth, and it is easy to cause water accumulation. If the water accumulation is not discharged for a long time, it will easily lead to plant root rot. If the waterproof layer is in the water accumulation environment for a long time, it is easy to cause partial waterproof layer. Leakage, and because the traditional ...

Problems solved by technology

However, the traditional blind ditch drainage has limitations, local drainage is not smooth, and it is easy to cause water accumulation. If the water accumulation is not discharged for a long time, it will easily lead to plant root rot. If the waterproof layer is in the water accumulation environment for a long time, it is easy to cause partial waterproof layer. Leakage, and because the traditional concave-convex plastic drainage board is unorganized drainage, in the case of slope finding, the water will flow to the low point. If the lowest point is on the outer edge of the garage roof, the water will continue to seep into the side wall of the basement Backfilling the soil will increase the hydrostatic pressure of the basement outer wall. If the basement outer wall partially damages the waterproofing during the backfill process, it will directly lead to leakage of the basement outer wall and affect the service life of the building.
