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...
