Abstract

The invention provides a sewage interception permeable pavement method, which comprises the following steps: a permeable structure layer with a tooth-shaped groove is paved between a base layer and a cushion layer transition surface or the upper surface of the cushion layer is directly set to be a tooth-shaped groove structure; at least one layer of sewage interception groove is laid in the base layer; a permeable coating or fine sand is arranged at the bottom of the sewage interception tank; according to the invention, the dirt between the base layer and the cushion layer which is originally most likely to cause gap blockage is trapped in the base layer, and the dirt is removed from the shallow layer part close to the surface layer through high-pressure washing operation; through the adjustment to basic unit and bed course structure, under the prerequisite that does not increase the thickness of mating formation, make the transition face between basic unit and the bed course delay because of the time that the design of tooth's socket type structure made the bed course receive filth blocking gap to make the life of permeating water and mating formation road surface increase.

Description

technical field [0001] The invention relates to a sewage intercepting and permeable pavement method, which is used for alleviating the problem that in the general permeable pavement process, the gaps are blocked by dirt and cannot be used under long-term use. Background technique [0002] The serious decline of groundwater level in modern cities has led to a series of hydrological changes in urban circles and the settlement of infrastructure facilities. The main reason is that in addition to the serious overexploitation of groundwater, large areas of land are covered by impermeable facilities, such as roads, buildings, parking lots, etc. Fields, etc., natural precipitation is not easy to seep into the ground from these underlying surfaces to replenish groundwater, and the accumulated water caused by heavy rain is likely to cause traffic congestion, damage to facilities, and spread of diseases. Such a vicious cycle has exacerbated the problem of depletion of urban groundwater ...
