Problems solved by technology

Permeable pavement allows rainwater to pass through directly and infiltrate into the soil below the pavement. However, permeable pavement has low strength and poor durability, so it can only be used in places such as low-traffic roads, parking lots, sidewalks, etc.

Embodiment 1

[0030] Such as Figure 1 to Figure 5 As shown, an example of the first water collection and then slow leakage drainage system described in the present invention is a water collection first and then slow leakage water system 1 for underground, including a water collection structure 2, a water leakage hole 6, a gravel layer 7, a water permeable Reinforced roof 8 and partition 9, the specific structure is: the wall of the water collection structure 2 is provided with a number of leakage holes 6, the outer side and bottom of the water collection structure 2 are provided with gravel layers 7, and the top of the water collection structure 2 is provided with The water-permeable and reinforced top cover 8 is provided with a partition 9 inside the water collecting structure 2 .

[0031] This embodiment can be used in parking lots, sidewalks, car dividers and other underground facilities.

[0032] The permeable and reinforced top cover 8 of this embodiment is used as the upper surface ...

Embodiment 2

[0034] Such as Image 6 As shown, the present embodiment is used on the ground for the first water collection and then slow leakage system, and utilizes the first water collection and then slow leakage drainage system to intercept roof rainwater for irrigation. The rainwater first enters the drainage system 1 through the rainwater pipe to first collect water and then leak slowly, and then injects into the green belt or other permeable surfaces through the leak hole 6 to infiltrate to replenish groundwater, prolong the irrigation effect of rainwater, and reduce the use of other irrigation equipment.

Embodiment 3

[0036]This embodiment is another example of the water-collecting first and then slow-leakage drainage system described in the present invention. It uses impermeable concrete slabs to make a concrete box without a roof with an inner diameter of 1m×0.5m×0.5m, and the concrete slabs are connected. Seal with glass glue. The short-side sidewall simulates a partition 9, and a water leakage hole 6 with an aperture of 1.5mm is opened on the long-side sidewall of the concrete box at a distance of 2.5cm from the bottom. The inside of the side wall of the concrete box is pasted with a scale with the same height as the box for real-time observation of water leakage and water level of the water tank. Place the concrete box inside a pre-excavated pit, that is, the slope of the concrete box is 0. The soil in the lower layer of the pit is silty clay with a permeability rate of 1.5×10- 7 m / s, the porosity is 18%, the saturation is 50%, and the bottom of the concrete box and the outside of th...

Abstract

A drainage system capable of achieving water collection and slow leakage successively comprises a water collecting structure, a rubble layer, a water permeating reinforcing rib top cover and a partition plate. The drainage system is specifically and structurally characterized in that a plurality of scour outlets are formed in the water collecting structure, a panel with water leakage holes is arranged on the inner sides of the scour outlets, the rubble layer is arranged on the outer side and the bottom of the water collecting structure, the water permeating reinforcing rib top cover is arranged on the top of the water collecting structure, and the partition plate is arranged inside the water collecting structure. The system has the advantages of being adjustable in water leakage speed, notprone to blockage and easy to maintain, can reduce surface runoff, relieve urban inland inundation, can maintain underground water balance and is a novel urban sponge body.

Description

technical field [0001] The invention relates to the fields of sponge city, urban drainage and municipal engineering, in particular to a drainage system that first collects water and then slowly leaks. Background technique [0002] In the process of urbanization, the natural surface is mostly covered by impermeable materials such as concrete and stone slabs. The rainfall falling on these dense and impermeable surfaces forms surface runoff, and the rainwater is discharged to rivers or other water collection facilities through drainage facilities such as storm sewers and gutters. Waterlogging occurs in low-lying areas when the surface runoff from rainfall exceeds the discharge capacity of the drainage system or exceeds the catchment capacity of the water collection facilities. If large-volume storage tanks or ponds are built inside the city to store the runoff that the drainage system cannot bear, urban waterlogging can be reduced to a certain extent, but such methods aggravat...
