More Information
Summary:The utility model relates to a high-strength geogrid preshaping punching die. Long circular female die holes with two parallel sides and two semicircular ends are formed on a female die plate, and long circular male die punch heads corresponding to the female die holes are installed on a male die plate. By punching the long circular holes on a polyolefine plate, the geogrid can be under balanced stress when being stretched, and the strength of the product can farther exceed the requirement on product strength in National Standard GB/T 17689-2008 for plastic geogrid made of geotechnical composite material, thereby meeting the demand for the current large-scale projects.
