PP grating is a high-strength geosynthetic material. Widely used in embankments, tunnels, docks, highways, railways, construction and other places. The main uses of PP grating are as follows: strengthening the roadbed, effectively distributing dispersed loads, improving the stability and bearing capacity of the roadbed, and extending its service life. Can withstand larger alternating loads; Prevent roadbed deformation and cracking caused by the loss of roadbed materials; This improves the self bearing capacity of the backfill behind the retaining wall, reduces the soil pressure on the retaining wall, saves costs, extends its service life, and effectively reduces maintenance costs.
Combining shotcrete and anchor concrete construction methods for slope maintenance can not only save 30% -50% of investment, but also shorten the construction period by more than twice; Adding geogrids to the roadbed and surface of highways can reduce deflection. Reducing ruts and delaying the appearance of cracks by 3-9 times can reduce the thickness of the structural layer by up to 36%; Suitable for various soils, without the need for remote material selection, saving labor and time; The construction is simple and fast, which can greatly reduce construction costs.
PP grating is used for railway ballast protection. Due to train disturbance and wind and rain, the ballast is lost. Geogrids are used to wrap the ballast to avoid loss and improve the stability of the roadbed; PP grating is used for railway retaining walls, while geotextile grating is used for strengthening retaining walls on railway sides, such as railway station platforms and freight platforms, which can extend their service life and reduce repair costs. Strengthen and reinforce soft soil foundations such as highways, railways, and water conservancy. PP grating has high tensile strength, high tear resistance, and strong adhesion with soil gravel. PP grid has a very obvious effect on strengthening and reinforcing soft soil foundations such as highways, railways, and water conservancy.
Low elongation, corrosion resistance, aging resistance, and strong bite strength with the base material. Lightweight and drainage effect. The polyester grille is made of high-strength polyester industrial filament and is coated with directional woven mesh fabric. It is used for soft soil foundation treatment and reinforcement of roadbed, embankment, and other projects to improve engineering quality and reduce engineering costs.
