preparation example Construction

[0051] In the present invention, the preparation method of the base layer preferably includes: mixing water, fly ash, cement, recycled aggregate and a water reducer, laying it on the surface of the cushion layer to form the base layer on the surface of the cushion layer. In the present invention, the order of adding materials during mixing is preferably: firstly mix the recycled aggregate, fly ash and cement, and then add water and water reducing agent to the resulting mixture in sequence; the mixing method is preferably stirring; The method of laying is preferably as follows: according to the actual road surface width, the formwork is fixed on both sides of the road; the slurry is poured on site; the flat vibrator is selected to vibrate the slurry and the height is controlled within the required range; after the control of the mixture is completed, the Timely maintenance, maintain a certain humidity, should not be too dry or too wet; the curing period is not less than 7 days, ...

[0085] First mix lime and fly ash to obtain a dry mixture; then mix the dry mixture with ferrochrome slag and water to obtain a slurry; lay the slurry on the surface of the soil foundation to form a pad on the surface of the soil foundation layer; the consumption of the lime, fly ash, ferrochrome slag and water is shown in Table 5; the thickness of the cushion layer is shown in Table 6;

[0086] Mix water, fly ash, cement, ferrochrome slag + granite waste rock (the mass ratio of ferrochrome slag and granite waste rock is 1:1) and water reducer, and lay it on the surface of the cushion layer. Form the base; the consumption of the water, fly ash, cement, ferrochrome slag+granite waste rock (the mass ratio of ferrochrome slag and granite waste rock is 1:1) and water reducer is shown in Table 5; See Table 6 for thickness;

[0087] A geotextile is laid on the surface of the base layer, and then a perforated high-density polyethylene drainage pipe wrapped in a permeable geotextile ...

Abstract

The invention relates to the technical field of permeable concrete pavements, in particular to a semi-permeable pavement system and a pavement rainwater collection system, so as to solve the technicalproblems in the background technology. The semi-permeable pavement system comprises a cushion layer, a base layer, geotechnical cloth, a drainage pipe layer, a permeable concrete lower surface layerand a permeable concrete upper surface layer which are sequentially arranged from bottom to top, and a plurality of water permeable holes are formed in the pipe wall of the drainage pipe. The semi-permeable pavement system prepared from the solid waste material can achieve the effects of collecting and discharging rainwater, effectively supplement underground water and relieve sharp drop of urbanunderground water, is beneficial to urban rainwater management and water pollution treatment, and has relatively high economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of permeable concrete pavement, in particular to a semi-permeable pavement system and a pavement rainwater collection system. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge and has good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The significance of building a sponge city lies in adopting measures such as infiltration, stagnation, storage, purification, use, and drainage to absorb and utilize rainfall on the spot, to give full play to natural ecological functions and artificial intervention functions, to effectively control rainwater runoff, and to realize natural accumulation and natural pollution. Infiltration and natural purification are conducive to restoring urban water ecology, conserving water resourc...
