In the case of the subgrade with Geogrid
Geogrid is divided into four categories: plastic geogrid, steel plastic geogrid, fiberglass geogrid and polyester warp knitted polyester geogrid.
A grille is made of polypropylene, PVC polymer and thermoplastic or molded by two-dimensional grid or a certain height of the three-dimensional mesh screen, when used as a civil engineering, called geogrid. Geogrid is a kind of main geosynthetics, which has unique properties and effects compared with other geosynthetics. Geogrid is often used as reinforcement of reinforced soil structure or composite material
Geogrid is suitable for various kinds of dams and subgrade reinforcement, slope and tunnel wall reinforcement. Large airport, parking lot, wharf freight yard and other permanent bearing foundation reinforcement. The geogrid is used to increase the bearing capacity of the road (ground) foundation, and the service life of the Yan Changlu foundation. The geogrid is used to prevent the collapse of the road (ground) surface or crack, and keep the ground beautiful and tidy. The geogrid is convenient for construction, time saving, labor saving, shorten the construction period and reduce maintenance cost. Geogrid is used to prevent cracks in culvert. Geogrid is used to enhance soil slope and prevent soil erosion. The geogrid is used to reduce the cushion thickness and save the cost. Geogrid for stability of slope greening environment support grass mat. The geogrid can effectively isolate the seismic force transfer, and plays an important role in enhancing the seismic stiffness, strength and stability of the embankment. The successful application of geogrid is expected to reduce the common embankment diseases in high intensity seismic region, and improve the seismic capacity of the road. However, the current seismic design codes for highway and railway are not corresponding to the seismic performance of geogrid reinforced embankment.
When the subgrade for soft foundation treatment using geogrid, geogrid is used as reinforcement of reinforced earth structure or reinforced material, the main function is to play the role of tensile.
