Riverside slope protection anti-scour Reynolds pad application scope: river water slope, river slope, riverbed bottom, riverbank dam.
Reynolds pad is a metal mesh with high corrosion resistance and high tensile resistance, which has uniform and beautiful mesh, good overall structure and good seismic performance, and can resist the erosion of water flow of 6m/s.
Renault pad structure:
Reynolds pad is composed of end plate, side plate and cover plate, the length is 3 ~ 6m, the width is generally 2m, and the height is 0.17 m, 0.23 m, 0.30 m and other different models. The interior is divided into several cells by partition plates, and the unit specification spacing is generally 1m (partition plates have single version and double partition plates)
(2) According to international standards, the mesh size of Reynolds pad is 6cm × 8cm, the diameter of mesh wire is 2.2 ~ 3.2 mm, and the diameter of stranded wire is 2.0 ~ 3.0 mm. In order to strengthen the strength of Reynolds pad structure, all panel edges are made of steel wires with larger diameter, with a diameter of 2.7 ~ 3.7 mm; The allowable tolerance of mesh is-4% ~ +16%, and the mechanical strength of mesh surface is 35kn/m.
(3) The surface of steel wire used to produce Reynolds pad is galvanized, galvanized (5% Al-Zn alloy + rare earth element), galvanized and plastic coated, galvanized and plastic coated, etc. Compared with hot dip galvanizing, the durability of Galvanized coating in Reynolds pad products can be increased by 3 ~ 4 times.
Protective advantages of Renault pads:
(1) Good flexibility: As a composite structure with low carbon steel wire, Reynolds pad has strong flexibility, can adapt to the local subsidence deformation of foundation and protected body, and can adjust and heal by itself to prevent the continuous development of deformation.
(2) Good durability: Machine-woven hexagonal low carbon steel wire mesh surface and hard stone combine to form a large durable whole.
(3) Good environmental protection: The product is filled with stone that meets certain requirements to achieve the protective effect. In the waterfront environment, through the natural deposition of sediment, the surface of the product can grow vegetation rapidly, and promote the recovery of the surrounding micro-ecological environment, with perfect environmental affinity
(4) Good water permeability: The product has natural water permeability. After the installation of Renault pad, the water head after pad will not increase. At the same time, it can ensure the natural exchange between natural water body and groundwater, and further strengthen the environmental protection effect.
(5) Good integrity: The product is composed of independent units, but at the same time, each adjacent unit is twisted by steel wire, so it also has good integrity.
(6) Good economy: The stone needed by Renault pad can be crushed stone or pebbles which cannot be used by traditional structure, and the stone cost is low. No drainage system is needed, only limited mechanical equipment is needed, and no skilled workers are needed. If the design and construction are reasonable, the service life of the structure is long and maintenance is not required.
