Renault pad is a mesh pad woven from hexagonal low-carbon steel wire mesh, and the mesh pad is filled with stones that meet certain requirements to form a protective structure. The finish of the steel wire is galvanized and coated with plastic to prevent corrosion. The general specifications of Renault pads are 0.3m thick, 2m wide and 6m long.

The Renault pad structure is mainly used to protect hydraulic structures, river improvement projects and other hydraulic projects or waterway projects against hydraulic erosion and erosion. It can not only prevent the river bank from being damaged by water flow and wind and waves, but also realize the protection of water and downhill soil. The natural convection and exchange function among them achieves the ecological balance. Planting green on the slope can add landscape and green effect. It is named Renault Pad because its application is on the Reno River in Italy.

1. The main features of Renault pads include six aspects:

(1) Flexibility: As a combined structure with low-carbon steel wire, Reynolds pad has strong flexibility, can adapt to the local settlement deformation of the foundation and the protected body, and can self-adjust and self-heal, preventing the deformation from continuing to develop .

(2) Durable: The woven hexagonal low-carbon steel screen and hard stone form a large and durable whole.

(3) Environmental protection: Fill with stones that meet certain requirements to achieve the protective effect. In the water environment, after the sediment is deposited naturally, vegetation can grow faster on the surface and promote the recovery of the surrounding micro-ecological environment, so it has good environmental affinity.

(4) Water permeability: The water head behind the Renault pad will not increase after it is installed. At the same time, it can ensure the natural exchange of natural water and groundwater, further strengthening the environmental protection effect.

(5) Integrity: It is composed of independent units, but at the same time, each adjacent unit is twisted into a whole by steel wires, so it has good integrity.

(6) Economy: The stone required for Renault pads can be gravel or pebbles that cannot be used in traditional structures, and the cost of stone is low. No drainage system is required, and only limited mechanical equipment and skilled labor are required. If properly designed and constructed, the structure will have a long service life and require no maintenance.

2. The difference between single partition and double partition:

1. The manufacturing process is different: the cage of the double partition Renault pad is a one-piece cage, except for the cover, the other parts of the box are folded with mesh, that is to say, except for the cover and side panels , the end and bottom plates are inseparable. The single partition Renault pad adopts the assembly method, and the cover plate, side plate, end plate and bottom plate are produced separately and assembled into a net cage. Each part is wound and bound with spiral steel wire, and all side wires of the cage are made of thick wire to strengthen the strength of the gabion net.

2. The manufacturing process of the double partition Reynolds pad is relatively time-saving, but its stability is better than that of the single partition Reynolds pad.

3. In the cage of the same size, the expansion area of ​​the single partition Reynolds pad is smaller.
