Large-scale earthing basement roof drainage system

Technical Field

The utility model belongs to the technical field of drainage of large-scale constructional engineering, and particularly relates to a drainage system for a top plate of a large-scale earthing basement.

Background

The large-area drainage system of the top plate (or planted roof) of the earthing basement in the existing large-scale building engineering is mainly a siphon drainage system with higher cost. If a large-area drainage system is not adopted, excessive water in a planting soil layer above a basement roof (or a planting roof) cannot be smoothly discharged, the air permeability and the water permeability of soil cannot be maintained, the load of a building is increased, and water seepage of the structure is caused; if a siphon drainage system is adopted, the self price is high, the cost reaches 40-60 yuan/square meter, and the total cost is high due to the cost of slope finding concrete.

Therefore, there is a need to develop a drainage system for large-scale covered basement roof, which meets the drainage requirement of large-scale covered basement roof (or planted roof) and has low cost.

When the drainage system is used, redundant water in a planting soil layer of a top plate (or a planting roof) of a large-scale earthing basement is filtered through a filtering water layer and geotechnical cloth, and then is discharged to a designated position through a square pipe. Each square pipe in the drainage system can drain water bidirectionally, the drainage cannot be influenced due to local blockage, the smooth drainage is ensured, and the drainage requirement of a large-scale earthing basement roof (or a planted roof) is met. The water draining system has low cost, no waterproof layer and no concrete in 5 yuan/square meter, and has no need of slope finding and low cost. The concrete for finding the slope is calculated according to the thickening of 3cm, the concrete is calculated according to 500 yuan/cubic meter, and the cost for finding the slope is 15 yuan/square meter.

Further, a mortar layer for fixing the square pipe is arranged on the waterproof layer of the basement roof. The square tube can be more stable by fixing the mortar layer.

Furthermore, the gaps at the joints of the square pipes are blocked by mortar. Prevent the sundries in the later stage from entering the square tube and ensure the normal flow of water flow.

Further, the distance between the square pipes in parallel is less than or equal to 6 meters.

Further, the distance between adjacent water filtering holes is less than or equal to 200 mm. Enough water filtering holes can ensure the water draining effect.

Further, the diameter of the water filtering holes is 8-12 mm, and the diameter of the water passing holes is 16-24 mm.

Further, the thickness of the waterproof protective layer concrete is 50-70 mm.

Furthermore, the height of the square tube is slightly smaller than the thickness of the waterproof protective layer concrete. Thus facilitating the adjustment of elevation.

Further, the water filtering layer is composed of sand and stone, and the thickness is not less than 100 mm.

Further, the system includes a reservoir. The water discharged by the square pipe network is collected into the reservoir, and the water can be used for road dust fall and greening maintenance after the construction engineering is put into use, thereby achieving the purposes of energy conservation and emission reduction.
