Problems solved by technology

The filter and permeator of this device are installed at the bottom of the water collection well. The sediment in the rainwater runoff can easily cause the blockage of the filter and permeator. During the later use, frequent maintenance is required, which greatly increases the maintenance cost in the later period.
In addition, due to the limited area that can be covered by the water collection well in the city, the amount of rainwater that can be infiltrated within a limited time is not much, and the effect of groundwater recharge is not obvious.
[0005] In summary, the existing method and structure of sponge-type rainwater pipes for groundwater supply still have problems such as initial rainwater recharge underground polluting groundwater, solid particles are easy to block permeation devices, and recharge efficiency is low, which affects the quality and effect of rainwater recharge.

Embodiment 2

[0052] according to Figure 1-6 It can be seen that a method for utilizing sponge-type rainwater pipes to replenish deep groundwater, its implementation steps are:

[0053] (1) Construction preparation: Determine the material, size and quantity of sponge-type rainwater pipes, connecting pipes, permeation pipes, and filter screens according to urban rainfall characteristics, groundwater depth, and soil types, prefabricate sponge-type rainwater pipes, and prepare supporting permeation pipes, connecting pipes, filter screen;

[0054] (2) Construction lofting and foundation pit excavation: at the lofting position of the recharge well at the bottom of the foundation pit, adopt the spiral drilling and steel cylinder wall protection method specified in the "Water Conservancy and Hydropower Engineering Drilling Regulations" (SL291-2003) to form a depth of 10m-30m The wellbore of reinjection well;

[0055] (3) Install the reinjection well hole by hole: Put the connecting pipe connect...

Abstract

The invention discloses a device for utilizing a sponge-type rainwater pipe to supply deep groundwater. The device comprises the sponge-type rainwater pipe, a base, drainage pipes, filtering screens,communicating bent pipes, communicating straight pipes and permeation pipes, wherein the sponge-type rainwater pipe is arranged on the base, the drainage pipes are arranged at the two sides of the sponge-type rainwater pipe, the filtering screens are arranged at the ends, close to the sponge-type rainwater pipe, of the drainage pipes, the other ends of the drainage pipes are connected with the upper ends of the communicating bent pipes, the lower ends of the communicating bent pipes are connected with the communicating straight pipes, and the communicating straight pipes are connected with thepermeation pipes. When it rains, the device collects surface water, after rainwater is subjected to initial flow splitting and secondary filtering through the sponge-type rainwater pipe, the deep underground water is supplied through an inverted well, the problem that initial rainwater which has high content of pollutants runs off, is recharged and pollutes the underground water is solved, and the problem that rainwater containing solid particles runs off and flows into a permeation device and clogs permeation materials is also solved; meanwhile, the rainwater is directly introduced into a permeable layer, the recharging effect of the rainwater is improved, and the device is more environmentally friendly and more efficient.

Description

technical field [0001] The invention belongs to the technical field of urban drainage engineering, and in particular relates to a sponge road drainage facility, in particular to a device and method for supplying deep groundwater with a sponge-type rainwater pipe, which can be used for initial rainwater abandonment, urban rainwater regulation, and rainwater infiltration Structures and construction methods for replenishing groundwater. Background technique [0002] The traditional municipal road drainage design idea is mainly that rainwater generates runoff along the horizontal and vertical slopes of the road surface, and after the rainwater is collected, it is discharged to the water body through the rainwater pipe. With the development of urbanization, this kind of drainage idea of ​​"focusing on drainage and lagging utilization" will lead to a series of problems such as high pressure on road flood drainage, serious loss of rainwater resources, and damage to the ecological e...
