Sponge city road structure which avoids the deposition of pavement rainwater

Abstract

The invention provides a sponge urban road structure which avoids the deposition of pavement rainwater, comprising a roadway drainage asphalt pavement, a greening planting tray and an external drainage pipe. Two symmetrical middle protective plates are fixed through concrete mosaic at the inner end side of the roadway drainage asphalt pavement, and a concrete channel is arranged between the two middle protective plates. The invention comprehensively realizes a sponge city road structure avoiding pavement rainwater deposition through the mutual cooperation of the various structures, Construction of sidewalks, A 6CM thick permeable brick pavement pave through that sidewalk, 3CM medium sand level layer are sequentially laid under that water-permeable brick pavement of the sidewalk, 10CM permeable cement concrete base course and 10CM subgrade mixed with crushed stone, so that the sidewalk can reach more than 70% of the water permeability, and can create a low-carbon environmental protection of the natural living environment, maintain the ecological balance of the city, maintain good water permeability of the ground, moisture retention.

Description

technical field [0001] The invention belongs to the technical field of urban road drainage, and more specifically relates to a sponge city road structure for avoiding rainwater deposition on road surfaces. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water when needed. and take advantage of it. Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and ecological environment protection, and the construction of sponge city roads is also an important part of reflecting the concept...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a sponge city road structure that avoids rainwater deposition on the road surface, so as to solve the problem of reducing the durability of the road surface while pursuing high water permeability, and the road is soft and easy to sink It is easy to be blocked by the gravel brought by rainwater, resulting in a decrease in water-repellent capacity
