Problems solved by technology

[0003] Most of the current sponge city road construction adopts structures such as drainage pavement, open side stones, and concave green belts, which realize the road drainage function, but do not realize the functions of water seepage, water storage, water purification, and water stagnation.

Underground comprehensive pipe gallery 19, planting soil 20 and communication channel 21; the bottom of the sponge city road structure is provided with piles 13 and inverted arches 12, and the top of the piles 13 and inverted arches 12 is provided with an impervious floor 16, The two ends of the inverted arch 12 are provided with impermeable side walls 6, and the middle part between the inverted arch 12 and the impermeable floor 16 is provided with an underground integrated pipe gallery 19, and the two sid...

Embodiment 2

[0033] The construction method of described sponge city road structure, comprises the following steps:

[0034] 1) if figure 2 As shown, the road foundation pit is excavated, and the reinforced concrete prefabricated piles are laid to the design depth according to the design requirements, then the steel bars of the inverted arch 12 are bound, the formwork is set up and the concrete is poured to form the inverted arch 12, and then the steel bars reserved in the middle of the inverted arch 12 Bind the steel bars of the side walls of the underground comprehensive pipe gallery 19, pour concrete to form them, and finally bind the steel bars of the impermeable floor 16 on the top of the underground comprehensive pipe gallery 19 and the pile 13, and reserve the permeable openings 10 and vertical water pipes 11 at the corresponding positions After the channel and the inspection port 3, the concrete is poured;

[0035] 2) if image 3As shown, the impermeable side walls 6 are poured ...

Abstract

The invention relates to a sponge city road structure. The sponge city road structure comprises a permeable pedestrian path, lateral permeable kerbs, an access hole, an overground permeable roadway, a central green belt, an impermeable side wall, a leveling fine sand layer, geotextile, a graded filter layer, permeable holes, vertical water pipes, inverted arches, piles, an impermeable top layer, impermeable side walls, an impermeable bottom plate, an underground impermeable roadway, a ground sewer, an underground comprehensive pipe gallery, planting soil and a communication channel. Piles and inverted arches are arranged at the bottom of the road structure. The sponge urban road structure has the beneficial effects that the sponge urban road structure has urban overground and underground road construction, the structure is stable, the integrity is high, and the space is expanded; the permeable pavement and the vertical water pipes are adopted, and geotextile and a graded filter layer are used as base layers, so that water is drained, seeped and stagnated in time, and meanwhile, a water purification effect is achieved; the inverted arch and the piles are adopted to replace a traditional roadbed, the structure is stable, rain wash and underground water erosion are avoided, and ground water is effectively collected and drained.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a sponge city road structure and construction method. Background technique [0002] It has become a new situation to coordinate the above-ground and underground construction of the city, start the construction of more than 2,000 kilometers of urban underground comprehensive pipe corridors, start the three-year action to eliminate key waterlogged areas in the urban area, and promote the construction of sponge cities. Under the new situation, the sponge city is an innovative expression of promoting the construction of green buildings, the development of low-carbon cities, and the formation of smart cities. It is an organic combination of modern green technologies and various factors such as society, environment, and humanity under the background of the characteristics of the new era. Sponge city is a new generation of urban stormwater management concept. It means that the ...
