Abstract

The invention discloses a honeycomb type plastic civil engineering grid and a production technology, and relates to a manufacturing method for environment and ecological protection slope protection and sand stabilization products. The product body materials include polyvinyl chloride, neutral filament glass fiber, maleic anhydride graft modification chlorinated polyethylene, tetra pod zinc oxide whiskers, ACR, rutile titanium dioxide, a plasticizer, an inner and outer lubricating agent, a heat stabilizer and a PVC elastic body. Solving the problems that existing plastic civil engineering grids made of polyethylene, polypropylene and the like are poor in light aging resistance and strength, poor in brittleness resistance, and welding points are cracked is the purpose. The light aging resistance, the strength, the brittleness resistance and elasticity of the honeycomb type plastic civil engineering grid are improved, and the service life of the honeycomb type plastic civil engineering grid is prolonged; using is convenient, fast and reliable; and meanwhile, the production technology is simple, and cost is low. The honeycomb type plastic civil engineering grid is suitable for earth surface soil permanent curing and repairing, environment greening, river and canal protecting and the like, and is particularly suitable for slope protection, sand stabilization and the like.

Description

technical field [0001] A honeycomb plastic civil grid and its production process belong to the field of civil engineering and relate to a method for manufacturing slope protection and sand-fixing products for environmental and ecological protection. Background technique [0002] The methods of vegetation coverage, block stones, prefabricated or cast-in-place concrete block structures are mostly used in slope protection projects, desert control projects, permanent solidification and restoration of surface soil, and greening environment in river channel regulation projects. It has certain advantages such as permanent solidification and restoration of surface soil, good landscape effect, convenient construction, and good landscape effect. The disadvantage is that the operation period is relatively short. Generally, some slopes will appear on the slope within 3 to 5 years. Damaged, resulting in poor landscape effect. More importantly, the problem of soil erosion still occurs. ...
