Abstract

The invention discloses a rainwater utilization structure with enhancing water-storing for a sponge city ecological square. The rainwater utilization structure is arranged between the square and a motor vehicle way. Filled soil subgrade of the square is a water permeable surface layer, a water permeable concrete layer, a graded crushed rock layer and a punning pure soil layer in sequence from top to bottom. Filled soil subgrade of the motor vehicle way is a road asphalt layer, a road concrete layer and a punning pure soil layer in sequence from top to bottom and comprises an ecological isolating mound, and a water-storing tank. The ecological isolating mound is arranged on the permeable concrete layer, the top part of the ecological isolating mound is exposed to air, and the bottom of the ecological isolating mound communicates with the graded crushed rock layer. The ecological isolating mound is internally provided with planting soil and a water-absorbing strip for plant growth. The water-storing tank is arranged on the punning pure soil layer. One end of the water-absorbing strip is arranged in the planting soil, and the other end of the water-absorbing strip is arranged in the water-storing tank. The rainwater utilization structure has the advantages such as construction is convenient, the rainwater utilization structure is energy-saving and environmentally friendly, the rainwater utilization rate and the urban landscaping rate are improved, the cost is low, and the maintenance is simple.

Description

technical field [0001] The invention relates to the technical field of environmental protection urban construction, in particular to a rainwater utilization structure of a sponge city ecological square with enhanced water storage. 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 pavement in the whole city is about 30%. There are problems of runoff pollution and waste of water resources caused by...
