Sponge city ecological infiltration ground structure and construction method thereof

Abstract

The invention discloses a sponge city ecological infiltration ground structure and a construction method thereof and belongs to the field of urban construction environmental protection. The key pointof the technical scheme is that the sponge city ecological infiltration ground structure comprises a subbase course, a base course, an infiltration course, a water permeable ground and curbs which arearranged from bottom to top, wherein the base course is arranged on the subbase course; the infiltration course is arranged on the base course; the water permeable ground is arranged on the infiltration course; the curbs are arranged on the two sides of the base course; a reinforcing component is arranged in the infiltration course; the reinforcing component comprises vertically arranged load bearing rods and bearing nets, wherein the bearing net is arranged on the load bearing rods; the load bearing rods extend to be buried in the subbase course and the base course; multiple layers of bearing nets are arranged in the vertical direction and are fixedly connected with the load bearing rods; a plurality of reinforcing rods are arranged between the two adjacent bearing nets; and the bearingnet is fixedly connected with the curbs. According to the sponge city ecological infiltration ground structure, as the infiltration layer and the reinforcing component are arranged, the strength of the ground can be enhanced while the ground water seepage is realized.

Description

technical field [0001] The invention relates to the field of urban construction and environmental protection, in particular to a sponge city ecological infiltration ground structure and a construction method thereof. Background technique [0002] With the rapid development of urban construction, the construction of a large number of buildings and roads has rapidly increased the urban hardened ground area. At present, the pavement design of most urban roads and public squares in my country adopts the concept of "coordinated development of nature and a virtuous cycle of ecology" An impermeable densely graded concrete and stone slab paving structure that contradicts the concept. The large-scale use of this kind of pavement will have a negative impact on the urban ecological environment, destroy the normal circulation of water resources, completely prevent rain (snow) water from directly penetrating into the ground, and block the impact of rain (snow) water on urban groundwater. ...

Problems solved by technology

[0004] The construction method of this sponge city ecological infiltration ground, although the advantages of the invention are: the construction method is ecological, environmentally friendly, green, has good repeatability and reproducibility, and can increase the porosity and rainwater permeability of the ground; significantly Improve the water storage performance and pollutant purification capacity of the road surface and surrounding soil, reduce the occurrence of water pollutants and road safety accidents, moderately adjust the local climate, and significantly slow down the city's "rainwater disease", "heat island effect", soil water shortage and urban noise While solving the problems of urban ecology, environment and safety, it has served as a good reference for the construction of urban ecological roads. However, due to the setting of the permeable layer in the actual use process, after the permeable ground is under pressure, the pressure transfer The percolation layer will be deformed, which will lead to a decrease in the overall strength and structure of the pavement, resulting in damage to the pavement
