Problems solved by technology

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. The supplement of resources; exacerbated the negative climate effect of the city and deteriorated the urban ecology. This kind of impermeable pavement will work together with the surrounding urban buildings, which will increase the city's "heat island effect" and urban noise; increase safety hazards

Embodiment 1

[0019] A method for constructing the ecological infiltration ground of a sponge city, such as figure 1 As shown, the sponge city ecological infiltration ground is composed of subbase, base, infiltration layer, and permeable pavement, and the construction method includes the following steps:

[0020] 1) Preparation of percolation material

[0021] The percolation material is made by combining natural materials, waste materials and artificial materials, among which the natural materials are natural sand, zeolite, quartz sand, wood, meadow soil or sandy soil, and the waste materials are coal ash, crab shell or solid waste The artificial material is fiber membrane, activated carbon or zero-valent iron. According to the percolation effect and economic efficiency, the ratio of natural materials, waste materials and artificial materials is 7:2:1;

[0022] 2) Lay the subbase and base

[0023] Excavate the subgrade according to the design requirements, clean up the earthwork, check t...

Embodiment 2

[0030] A method for constructing the ecological percolation ground of a sponge city, the ecological percolation ground of the sponge city is composed of a subbase, a base, a percolation layer, and a permeable pavement, and the construction method embodiment 1 is basically the same, the difference is that:

[0031] In step 1), the proportion of natural materials in the percolation material of the percolation layer is appropriately increased, and the material ratio of natural materials, waste materials and artificial materials is 7:1:0.5.

[0032] In step 2), the laying thickness and compaction coefficient of the subbase and the base can be properly reduced according to the actual situation. According to the requirements of the design, excavate the roadbed, clear the earthwork, lay a 15cm thick lime fly ash stabilized soil subbase layer above the excavated roadbed, and then lay a 10cm base layer after paving and compacting, using cement fly ash to stabilize, The paving is compac...

Abstract

The invention discloses a method for constructing ecological infiltration pavement in a sponge city. The ecological infiltration pavement in the sponge city comprises a subbase layer, a base layer, an infiltration layer and a permeable pavement. The construction method comprises steps as follows: 1) an infiltration material is prepared; 2) the subbase layer and the base layer are paved; 3) the infiltration layer is paved by paving the infiltration material under the pavement; 4) curbs are mounted and the permeable pavement is paved. The method has the advantages as follows: the construction method is ecological and environment-friendly and has better repeatability and reproductivity, and the porosity and the rainwater infiltration rate of the pavement can be increased; the water storage performance and the pollutant purification capability of the pavement and surrounding soil can be remarkably improved, pollutants in water and road safety accidents are reduced, the local climate is moderately adjusted, the problems such as rain diseases, the heat island effect, soil moisture deficiency, city noise and the like of the city are remarkably solved, and a good reference function is provided for construction of urban ecological roads while the problems about urban ecology, environment and safety are solved.

Description

technical field [0001] The invention belongs to the field of urban construction and environmental protection, and in particular relates to a method for constructing a sponge city ecological infiltration ground. 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 "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. The supplement o...
