Embodiment example 2

[0016] Implementation case 2, a village-level road surface of 1,200 square meters in Wenjiang District, Chengdu was selected. The construction time was June 2010. The soil in this area is weakly expansive soil, and it is very difficult to replace and treat. The mixture ratio is: soil water control agent : Soil=0.23%: 99%, wherein, plain soil is local site soil. The surface layer is not covered with asphalt, but pea stone is used as the surface layer to prevent slipping. The compressive strength tested by the authoritative testing station of Chengdu Highway is 3.8Mpa, and the deflection is 38. Compared with the traditional cement concrete process, it saves only 180% of sand and gravel. tons, saving part of the consumption of transportation fuel, reducing the emission of carbon dioxide by more than 6 tons, protecting the atmospheric environment, and the significance of environmental protection is very significant.

Embodiment example 3

[0017] Implementation case 3, choose a village-level greenway along the river in Xinjin, Chengdu, about 30 kilometers away, and choose summer construction. Use this kind of soil water control agent to mix 2 / 1000 and 6% cement evenly and then compact it. Sprinkle 2kg of stone powder per square meter on the surface and directly use it as the surface layer. It was completed in August 2008, and the core was taken in October 2010 to resist compression. The maximum strength is 8.5Mpa. It has been used so far without any cracks on the surface. The traffic is normal. It does not slip when it rains, and it does not ash when it is sunny.

Abstract

The invention provides an environment-friendly soil water controlling agent capable of directly converting soil into road surface layer. The soil water controlling agent can prominently improve the hardness of soil and control the water content, is very practical, is convenient for construction, and is capable of directly converting soil on site into a road surface layer. The soil processed by the water controlling agent can directly replace the cement layer and the asphalt layer only by mixing the soil with a trace amount curing agent. The compression strength can reach 3 to 8 MPa after 7 days. The soil layer can directly replace the basic layer, the water stabilizing layer, and the surface layer in road construction, and the construction cost can be reduced by 30 to 50%. The soil layer has the advantages of low cost, simple construction, good fireproof and anti-seismic property, and durability. A novel road basic layer and surface layer construction method is provided. The road composed of the soil processed by the water controlling agent can be crushed for cultivation in the future, and thus the road is according with the social development trend of scientificity, environment-friendliness, ecology, and energy saving.

Description

Technical field [0001] The present invention relates to the technical field of road and building construction, and in particular relates to a soil water control agent for directly treating soil into a road surface layer. It is suitable for a part of rural roads, urban greenways, garden roads, agricultural bases, and park road construction projects, and belongs to the field of fine chemical technology. Background technique [0002] The application technology of soil water control agent, along with the central and local government's emphasis on environmental protection and ecology this year, this environmental protection technology is more and more recognized and promoted by everyone, because this technology has some advantages, it can use local materials to reduce pollution , Reduce the mining of sand and gravel, and save costs. More and more projects have begun to use it, but the level of this technology is uneven, so it is more used for roadbeds. Our company has experienced...
