Problems solved by technology

[0004] In the prior art, the water storage function of the green belt is limited, and the areas of the green belt are separated by tree ponds, which cannot be effectively connected, resulting in sufficient water in some areas, and watering in some areas, which increases the frequency of watering and increases labor. Strength, so there is an urgent need for a sponge city road that uses breathable and anti-seepage sand to solve the above-mentioned problems

Abstract

The invention provides a sponge urban road adopting ventilated seepage-proof sand, including driveways and green belts, wherein the each driveway is sequentially provided with a permeable brick layer,a coarse sand layer, a gravel layer, a filter layer, an aquifer layer, a water-stable layer and a soil base layer from the top to the bottom; the each green belt is sequentially composed of a first permeable impermeable sand layer, a grass-planting brick layer, a medium sand layer, a planted soil layer, an aquifer layer, a second permeable impermeable sand layer and a soil base layer from top tobottom; a filter pipe is arranged in the filter layer, and a plurality of diversion pipes are arranged on the filter pipe, and the diversion pipes are deep into the aquifer layer; the driveways of theinvention is not separated from the water storage layer of the green belts, and the structure adopted by the driveways in rainy days can absorb and store water, thus being favorable for storing rainwater to provide water for plants in the green belt, and greatly reducing the watering frequency and labor intensity.

Description

technical field [0001] The invention relates to a sponge city road using air-permeable and anti-seepage sand and a construction method thereof, belonging to the technical field of application of air-permeable and anti-seepage sand. Background technique [0002] Breathable anti-seepage sand is a kind of anti-seepage material with breathing function developed through the principle of "enhancing the surface tension of water" and using desert aeolian sand as raw material. Use breathable anti-seepage sand and form a systematic water-saving solution (including water bodies, river channel anti-seepage systems and ecological planting systems). It can realize various functions such as water anti-seepage, water quality maintenance, ecological planting, saline-alkali soil anti-seepage, etc., and improves the ecological environment while effectively saving water resources. [0003] Sponge city is a new generation of urban stormwater management concept, which means that cities have good...
