Sponge sidewalk

Abstract

The invention discloses a sponge sidewalk. The sponge sidewalk comprises a body which comprises water-permeable bricks, a gap convenient for quick seepage of rainwater is reserved between every two adjacent water-permeable bricks, sand-based water-permeable curbs are arranged on two sides of the water-permeable bricks, and a water-permeable base layer is arranged below a water-permeable surface layer which is arranged below the water-permeable bricks. A pipeline network for rainwater collection is pre-embedded in the water-permeable base layer, water drain ditches are formed on two sides of the water-permeable base layer, two ends of the pipeline network are connected to the water drain ditches respectively, a plurality of irrigation pipes connected with surrounding green belts are arranged in the water drain ditches, and water guide pipes are arranged at two ends of the water drain ditches and connected to rainwater ports. By quick seepage and quick flow of water, water accumulated on the sidewalk can be drained quickly, and when rainwater internal storage is saturated, excessive rainwater can be stored and released when needed, so that water logging pressure of the sidewalk can be relieved; due to connection with the surrounding green belts, plant growth regulating agents can be provided, water supply demands of the surrounding green belts can be met, and urban landscape water quality is effectively improved.

Description

technical field [0001] The invention relates to the technical field of building construction, more specifically, it relates to a sponge sidewalk. Background technique [0002] With the continuous development of cities, many "over-urbanization" phenomena have emerged, resulting in a series of contradictions and problems called "urban diseases": traffic congestion, environmental pollution, water shortage, urban waterlogging, urban heat island effect, etc. Wait. [0003] Urban planning and construction must consider the impact on nature in every detail, not to mention breaking the natural system. When upgrading the urban drainage system, it is necessary to give priority to retaining limited rainwater, give priority to more use of natural forces to drain water, and build a "sponge city" with natural accumulation, natural infiltration, and natural purification. [0004] Sponge city reconstruction projects generally adopt only the replacement of permeable pavement surface in sid...

AI Technical Summary

Problems solved by technology

[0004] Sponge city reconstruction projects generally adopt only the replacement of permeable pavement surface in sidewalk reconstruction, and naturally drain excess water by lateral slope. When the permeable surface is saturated with water, it cannot penetrate downward quickly, forming a large amount of water on the surface , when the temperature is low in winter, the stored water will freeze, making the road surface more slippery and even damage the paving bricks through volume expansion, causing the road surface to be slippery and making it difficult for people to walk. To solve such problems, we cannot rely on natural evaporation or saturation from the top surface The method of dispersing should be carried out before causing water accumulation on the road.
