Reynolds pads are hexagonal nets woven by high-quality low-carbon steel wire or PVC machines, with plastic coating on the surface, mainly used for slope protection, anti-scouring at the bottom of river beds, etc. Reynolds pad, also known as Gabion pad, Gabion pad, refers to a pad-like engineering component whose thickness is much smaller than the length and width, and is made of woven twisted hexagonal metal mesh. Reynolds pads are connected by filling materials such as rocks, and are mainly used as anti-scouring structures for water conservancy dikes, bank slopes, seawalls, etc. It has the advantages of flexibility and adaptability to the foundation.

The Renault pad is a mesh cage structure with a thickness of 0.17-0.3m. It is used for on-site rock filling and is mainly used as a slope protection structure for rivers, bank slopes, and roadbed slopes. The use of Renault pads can not only prevent water flow and wind and waves from damaging the river bank, but also realize the natural convection exchange function between water body and soil under the slope, so as to achieve ecological balance. Planting green plants on the slope can increase the landscape and greening effect. The difference between Renault pads and gabion cages and gabion cages is that the height of the pads is low and the structure is flat and large. The diameter of steel wire coating is thinner than that of gabion, generally there are two kinds of double separator (wire diameter 2.0mm) and single separator (2.2mm). Double partition Renault pad is a commonly used pad, which has the advantages of convenient construction, slope protection, effective prevention of stone collapse, and increased structural erosion resistance.

Renault pad features: 1. Improve the stability of the river bed slope. 2. Protect the river bed from erosion. 3. Provide the predetermined value of the roughness coefficient of the river bank. 4. Greening and ecological protection of slope protection and bank protection. 5. Convenient construction.

Material of Renault pad: (1) Galvanized steel wire: high-quality low-carbon steel wire with a diameter of 2.0MM-4.0MM and a tensile strength of not less than 380Mpa. The surface of the steel wire is protected by hot-dip galvanizing, and the thickness of the galvanized protective layer is made according to customer requirements. (2) Zinc-5% aluminum mixed rare earth alloy steel wire: This is a new material in the world in recent years, its corrosion resistance is more than three times that of traditional pure galvanized steel wire, the diameter of the steel wire can reach 1.0-3.0 mm, and the tensile strength of the steel wire Not less than 1380 MPa. (3) Galvanized steel wire plastic-coated: high-quality low-carbon steel wire, wrapped with a layer of PVC protective layer on the surface of the steel wire, and then woven into hexagonal nets of various specifications. This PVC protective layer will greatly increase the protection in highly polluted environments, and through the selection of different colors, it can be integrated with the surrounding environment.

To sum up, the Renault pad is a cage structure composed of metal mesh with a thickness of 0.17-0.5m. The cage is filled with stones, and then multiple cages are connected into a whole. One or more partitions are added to the box of the Reynolds pad to strengthen the firmness of the Reynolds pad. The diameter of the steel wire on the edge of the mesh used is larger than the diameter of the steel wire used on the mesh to increase the tensile strength of the Reynolds pad. Renault pads are mainly used for slope protection of water conservancy embankments, river regulation, road protection, reclamation projects, etc. Its advantages are strong adaptability and good flexibility.
