Embodiment Construction

[0056] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0057] Such as figure 1 Shown: Using industrial waste-phosphorus slag, according to the different requirements of the density and porosity of each structural layer on the ground, adding different proportions of phosphorus slag fine powder, gypsum, lime, and stone (block) materials to become a new permeable mixed material . Wherein: the raw material used in the surface layer (1) is phosphorus slag water-permeable mixture with a thickness of 60mm, a compactness of ≥95%, and a porosity of 18%-20%. The weight ratio of the mixture per cubic meter is: 60:7:9:9:15; the raw material used in the base (2) is phosphorus slag permeable mixture, the thickness is 100mm, the compactness is more than 95%, and the porosity is 18%. -20%. The weight ratio of the mixture per cubic meter is...

Abstract

The invention discloses a novel mixed material for a pervious area (pavement), applicable to such urban slow-moving traffic roads as urban greenway, sidewalk, sidewalk (roadway) in residential area, parking lot and playground as well as open activity space, and a construction method of the mixed material. The novel mixed material is prepared on the basis of properties of yellow phosphorus residue (phosphorous slag) by mixing proper amounts of phosphorous slag powder, lime and gypsum. Raw materials in various proportions can be mixed depending on different requirements of functions in various layers of the ground, so that surface layer of the ground, while satisfying a requirement on surface density of urban slow-moving traffic load effect, can still keep porosity at 18-20%, and rainfall can rapidly permeate into a structural layer through the surface layer and basic layer. The structural layer can still keep high porosity, thus serving as a reservoir layer. Rainfall permeating into the surface layer can be completely absorbed, so as to avoid accumulated water on the ground. The ground is free from a runoff phenomenon even though heavy rainfall. The mixed material disclosed by the invention, compared to general pervious areas, is better in water permeation and water storage effects, and the advantages of being low in cost, energy-saving, and capable of making use of waste and avoiding pollution.

Description

technical field [0001] The invention relates to a water-permeable ground (road) surface (hereinafter referred to as the ground) phosphorus slag permeable for urban greenways, sidewalks, pedestrian (vehicle) sidewalks in residential areas, parking lots, playgrounds and other urban slow traffic roads and open-air activity venues. Mixed materials and construction methods. Background technique [0002] The status and utilization level of water resources have become important indicators for evaluating the sustainable economic development of a country or region. my country is a country with relatively poor water resources. Especially in recent years, with the rapid economic development, overexploitation of groundwater and environmental pollution, many usable water resources have been destroyed, and we are facing the threat of large-scale water shortage. The groundwater resources are mainly formed by the direct infiltration of atmospheric precipitation and the infiltration of sur...
