Abstract

The invention discloses a sponge engineering system based on an existing urban road and a drainage condition and belongs to the technical field of urban road drainage and rainwater utilization. Road surfaces of a motorized vehicle lane, a non-motorized vehicle lane and a pavement keep unchanged; water collection side ditches are formed in an outer side of the motorized vehicle lane along a road flat teeth part, and a road flat teeth part between the non-motorized vehicle lane and the pavement; gap cover plates cover the water collection side ditches; dredging wells are arranged along the water collection side ditches every 5m to 6m; the water collection side ditches are connected with a round water seepage and storage tank and a square water seepage and storage tank through inclined collection pipes respectively; the water collection side ditches are connected with a municipal rainwater pipe through overflow pipes. The invention further discloses a construction method of the system. By adopting the sponge engineering system and the construction method, an existing drainage system is not changed and burden of downstream drainage is effectively alleviated; pollution to a downstream water body, caused by initial rainwater pollution of the road surface, is avoided; disturbance on the existing rod surface and arbor planting is not caused; the construction is convenient and the road does not need to be blocked; interference to traffic is not caused, water resources are saved and the sponge engineering system and the construction method have promotional value.

Description

technical field

[0001] The invention belongs to the technical field of urban road drainage and rainwater utilization, and in particular relates to a sponge engineering system based on existing urban road and drainage conditions and a construction method thereof. technical background

[0002] In recent years, road waterlogging caused by heavy rainfall has been a chronic disease that affects pedestrian travel and even endangers urban traffic safety. It is common in Chinese cities. On the one hand, traditional asphalt or cement pavement surface drainage can only be carried out through storm water outlets, which is time-consuming It is long and prone to air resistance, and poor drainage leads to water on the road, which will not only cause vehicle tires to slip and become a safety hazard, but in areas with more water, it will seriously cause vehicles to be soaked in water and be scrapped, and pollutants will overflow to cause environmental pollution; On the one hand, there is a ...
