Sidewalk and greenbelt water collecting and storing system

Abstract

The invention provides a rainwater collecting and storing system of a sidewalk and greenbelts on the two sides. The system is composed of the sidewalk, a water permeable pipe and the greenbelts. The sidewalk is a road formed by laying water permeable bricks. The water permeable pipe is embedded in a road under layer, and a base layer, a leveling layer and a brick layer are arranged on the road under layer. The greenbelts are composed of planting base layers, coarse sand filter layers and crushed pebble layers. The planting base layers adopt artificial soil. Nonwoven geofabrics are arranged between the crushed pebble layers and the coarse sand filter layers. Garden bounding walls are built in the positions, from the upper edge of the road under layer to the position higher than the surfaces layers of the greenbelts, of the joints of the greenbelts and the road. The system is suitable for the ground or underground spatial top plates, and water can be filtered, stored and collected while the greenbelt area is increased. Greenbelt planting matrixes are low in weight and capable of holding water and effectively filtering harmful substances in rainwater, plants are not lack of water in the dry season with little rain, the rainwater can be filtered through the layers and is gathered at the water permeable pipe along with the gradient and collected to municipal water collecting pipelines in the heavy rainy season, and thus recycling of the water is promoted.

Description

technical field [0001] The invention belongs to the field of urban construction and design, and specifically provides a water collection and storage system for sidewalks and green spaces. Background technique [0002] my country is a country with drought and water shortage, but it is also the country with the largest water consumption in the world. In recent years, the tension of urban water resources has become increasingly significant, but many cities with sufficient rainfall cannot drain water in time to prevent flooding. In the summer of 2015, Hubei, Jiangsu, Anhui, Jiangxi, Zhejiang, Guizhou, Guangxi and other places were hit by "storms", tens of millions of people in 20 provinces (autonomous regions and municipalities) across the country were affected, a large number of crops were damaged, and the rainstorms and floods directly caused us Tens of billions of dollars of economic losses have been incurred, and the urgency of building a sponge city has become imminent.
