Sponge urban ecological sidewalk rain water utilization structure

Abstract

The invention discloses a sponge urban ecological sidewalk rain water utilization structure, which is arranged between a sidewalk and a motorway, wherein roadbed filled earth of the sidewalk is successively formed by a water permeable surface layer, a water permeable concrete layer and a rammed earth layer from top to bottom, roadbed filled earth of the motorway is successively formed by a road asphalt layer, a road concrete layer and a rammed earth layer from top to bottom and comprises an ecological isolation pier, the ecological isolation pier is arranged at the water permeable concrete layer, a grading crushed stone layer is also arranged between the water permeable concrete layer and the rammed earth layer, the top of the ecological isolation pier is exposed to the air, the bottom of the ecological isolation pier is communicated with the grading crushed stone layer, planting soil for a plant to grow and a water absorption strip are arranged in the ecological isolation pier, one end of the water absorption strip is arranged in the planting soil, and the other end of the water absorption strip is arranged in the grading crushed stone layer. The sponge urban ecological sidewalk rainy water utilization structure has the advantages that the structural construction is convenient, the energy is saved, the environment is protected, the rain water utilization rate and the urban green coverage rate are increased, the construction price is low, the maintenance is simple, and the like.

Description

technical field [0001] The invention relates to the technical field of environmental protection urban construction, in particular to a rainwater utilization structure for a sponge city ecological sidewalk. Background technique [0002] Sponge city is a new concept of urban construction proposed by the state. The Ministry of Housing and Urban-Rural Development requires that by 2020, more than 20% of the urban built-up area will meet the target requirements, and by 2030, more than 80% of the area will meet the target requirements. It can be seen from this that the country urgently needs to improve the living environment of residents and the urban water environment. The sponge city requires the city to have the functions of infiltration, stagnation, storage, purification, utilization and drainage when it rains. The proportion of square paving in the whole city is about 30%. There are problems of runoff pollution and waste of water resources caused by rainwater scouring the roa...
