Embodiment Construction

[0025] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0026] The sponge city sand well drainage system of the present invention, such as figure 1 As shown, it includes drainage channels 14 on both sides of the road 10, such as figure 2 As shown, the top of the drainage channel 14 has a number of mutually parallel reinforced concrete blocks 11. On the one hand, the reinforced concrete blocks 11 ensure the smoothness of the road surface and at the same time ensure that rainwater can flow down into the drainage channel 14. The bottom of the drainage channel 14 is evenly distributed. The side walls of the sand well 1, the drainage channel 14 are also connected to the greening unit through a PVC pipe 7.

[0027] As most parts of Northwest my country belong to the Loess Plateau, arid or semi-arid zone, urban greening has always been a problem. Urban greening can not only improve the sanitary conditions of the city, effe...

Abstract

The invention discloses a sponge city sand drain drainage system. The system comprises drainage channels located on the two sides of a road, multiple mutually parallel reinforced concrete blocks are horizontally arranged on the tops of the drainage channels, multiple sand drains are uniformly distributed at the bottoms of the discharge channels, and the side walls of the drainage channels are connected with greening units through PVC pipes. According to the sand drain drainage system, by means of combination of the drainage channels and the municipal drainage pipelines, the waterlogging problem of cities in northwest territories are solved; by arranging the sand drains in the drainage channels, the sand drains are filled with sand gravel, the collapsibility of city loess is relieved to a certain extent, the intensity of city foundations is enhanced, construction is simple, and the cost is low; rainwater collected in the drain channels is conveyed to the greening units on the two sidesof the road, the rainwater is collected, resources are reasonably allocated, the important role is achieved in city greening, and the system has the very good application value.

Description

Technical field [0001] The invention belongs to the technical field of urban drainage systems, and specifically relates to a sponge urban sand well drainage system. Background technique [0002] In the past 20 years, my country’s urbanization has been advancing rapidly, with the continuous expansion of urban area, the rapid increase of urban population, the rapid accumulation of social wealth, and the significant increase in the rate of urban ground hardening. The substantial increase in the urban permanent population and floating population has injected vitality into urban social and economic development, but it has also increased the risk of urban flooding and brought great challenges to urban flood control. At present, urban flood disasters show some new characteristics: urban rainstorms occur frequently and their intensity has increased sharply; urban rain and flood confluence has accelerated, which greatly exceeds the urban drainage capacity, and it is easy to form waterlogg...
