Plastic checkerboard sand-barrier net is made of high-density polyethylene mostly, it ventilation coefficient is 30%~45%. Compare to wheat strew sand barrier and clay sand barrier, its mechanism to fix shifting sands is different, has the advantages such as good effect on breaking wind and fixing shifting sands, technology simple, long period to use and easy to transport, also has the disadvantages such as high cost, bury and hollow out at the area of stabilization picket and under windward net which affect plastic sand barrier to extend seriously.
