Peak-Nest Type Plastic Civil Grating and Its Production Process

In river regulation projects, slope protection works, desert control projects, as well as projects for the permanent solidification and restoration of surface soil and environmental greening, methods such as vegetation cover, block stones, pre - cast or cast - in - place concrete block structures are often adopted. These methods have advantages such as certain permanent solidification and restoration of surface soil, good landscape effect, and convenient construction. However, their drawback is a relatively short service life. Generally, within 3 to 5 years, problems like slope collapse and bulging may occur on the slope, deteriorating the landscape effect. More importantly, soil erosion still occurs.

Our company has developed the most advanced honeycomb restraint system slope protection technology, which effectively solves the problem of soil erosion. It also overcomes the bottleneck that hinders large - scale application, namely, the issues of photo - aging, strength, brittleness, cracking of welded joints, and service life of the materials used - plastic geogrids made of polyethylene, polypropylene, etc.

Pieces of honeycomb - shaped plastic geogrids (modules) are connected into a carpet - like honeycomb slope protection with special connectors, then fixed deep in the soil with anchor rods, covered with soil, and finally planted with plants. The roots of the plants intertwine with each other in the gaps of the honeycomb - shaped plastic geogrids to form a huge network, firmly grasping the soil. After several years, a thick permanent soil crust layer is formed.
