Problems solved by technology

Not only will it seriously affect the image of the city and traffic safety, but it will also easily lead to poor drainage of the road and the formation of water on the road.
However, due to the many professional pipelines under the road and the obstruction of traffic during the construction period, the current old city road drainage reconstruction is very difficult, and the construction disturbs the residents, seriously affecting urban life.

Abstract

The invention discloses an urban road sponge engineering system combining pavement maintenance, and belongs to the technical field of urban road drainage and rainwater utilization. A sidewalk pavement is kept invariable, original structures of the portions under surface layers of a motorway and a non-motorized vehicle lane are retained, the thickness of the motorway and the thickness of the non-motorized vehicle lane are both decreased by 20-40 mm, then a water-permeable surface layer is repaved, the thickness of the water-permeable surface layer is 40-50 mm, and the outer edge of the water-permeable surface layer is next to a water collecting side trench cover plate; water collecting side trenches are arranged along a road flat curb on the outer side of the motorway and a road flat curb between the non-motorized vehicle lane and the sidewalk respectively, and the water collecting side trenches are connected with circular water permeating and storing tanks and square water permeating and storing tanks through oblique collecting pipes and connected with municipal rainwater pipes through overflow pipes. The invention further discloses a construction method of the system. Accordingly, an old urban road pavement is maintained and repaired, an existing sewage system is not changed, the downstream drainage burden is effectively reduced, pollution of initial pavement rainwater pollution to a downstream water body is avoided, and the practicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of urban road drainage and rainwater utilization, and in particular relates to an urban road sponge engineering system combined with road surface maintenance 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 la...
