Production process and structure
Divided by structural form: single diaphragm Reynolds pad and double diaphragm Reynolds pad
- Single diaphragm reno mattress (code M)
- Every 1 meter, use a vertical net as a diaphragm, and assemble the diaphragm with the bottom plate by tying wires, which is material saving, lightweight, and inexpensive, suitable for low flow rate and small area slope protection;
- Double diaphragm reno mattress (code D)
- The bottom plate and diaphragm plate are folded twice in a row as a net, forming a U - shaped reinforcement. The diaphragm plate and bottom plate are folded into the same net, with good overall integrity and strong anti bulging ability, allowing a height of 0.17-1.0m. It is the preferred choice for river slope protection.
| dimension | Single diaphragm | Double diaphragm |
|---|---|---|
| 1. Structural form | The diaphragm, bottom plate, and end plate are delivered in pieces and assembled with binding wires | Except for the cover plate, the bottom plate, diaphragm plate, and end plate are bent and formed in one go without binding wire joints |
| 2. Integrity/stiffness | Dependent on binding silk, slightly weaker in anti bulging and anti settling properties | Continuous bending, increased in-plane stiffness, good resistance to erosion and uneven settlement |
| 3. Unfolding area (same as 6 × 2 × 0.3 m example) | ≈38 m2 | ≈45 m2 |
| 4. Material weight/cost | About 15% lighter, 10% -15% lower unit price | Heavy and expensive, but saves on-site tying labor |
| 5. Applicable scenarios | Ditch, landscape lake, static water slope protection, flow velocity<3 m/s, insensitive to differential settlement section | Main river channels, flash floods, tidal zones, high-speed water flow of 3-6 m/s, with large elevation differences or soft foundation sections |

Double diaphragm reno mattress
Reno mattress advantage
- Good drainage:The mesh structure of reno mattress has excellent drainage, which can effectively remove moisture, avoid soil pressure problems caused by water accumulation, and reduce soil erosion..
- Strong flexibility and adaptability: Due to its flexible grid structure, reno mattress can adapt to soil surfaces of different shapes and slopes, making them suitable for use in complex terrains and different climatic conditions..
- Environmental Protection: Rock mattresses use natural materials (such as stone and gravel) and metal mesh, which comply with sustainable development principles and are a green and environmentally friendly engineering material.
- Simple and economical construction: The construction speed of gabion mattress is fast and relatively economical.. Due to their affordability and ease of transportation and installation, they are typically more cost-effective than traditional concrete structures.
- Durability: Due to the use of galvanized steel wire mesh, gabion mattress have excellent corrosion resistance and can resist the influence of natural environmental factors such as moisture and salt water, resulting in a longer service life.
- Ecological compatibility: The filling of stone or other natural materials provides conditions for plant growth, which can promote the rooting of plant roots, enhance ecological restoration and greening effects..

Note:
- Number of diaphragms=(length/1m) -1, ensuring an independent diaphragm every 1m to prevent lateral flow of stones.
- The width is fixed at 2 m, which is the most economical width, and can also be customized to 1 m, 1.5 m, or 3 m.
- Thicknesses of 0.17 m, 0.23 m, and 0.30 mare the three classic international series, commonly known as Type 17, Type 23, and Type 30..
Applications
- Protection of Rivers and Dams:
- Preventing erosion: reno mattress are commonly used in areas such as rivers, embankments, and lake shores to help prevent erosion caused by water flow and wind..
- Provide stability: Under the erosion of water flow, Renault pads can stabilize the bank slope and prevent soil erosion..
- Dam reinforcement and flood control engineering:
- Dam reinforcement: Renault pads are widely used for the protection and reinforcement of dams, which can effectively enhance the stability of dams and prevent soil erosion or water flow erosion..
- Flood protection: In the case of rainstorm or flood, Renault mattress can reduce flood damage to the dam by enhancing soil strength and drainage performance.
- Slope support and reinforcement:
- Slope reinforcement: In mountainous or sloping areas, Renault pads can effectively prevent landslides, collapses, and other phenomena, provide slope support, and prevent soil erosion..
- Landslide protection: Especially on unstable slopes, Renault pads can enhance soil stability and reduce the risk of landslides..
- Application in Water Conservancy Engineering:
- Canal protection: reno mattress are applied to the slope protection of canals to prevent water flow from scouring the soil..
- Wetland Protection: In wetlands or artificial water scenic areas, Renault pads can protect the shoreline of water bodies and prevent erosion caused by water flow..
- Coastal and Port Protection:
- Coastal Protection: Rock mattresses are commonly used for coastline protection to prevent erosion caused by waves, especially during tidal and storm weather.
- Dock reinforcement: Rock mattresses can also be used for protection around ports and docks, helping to prevent erosion of structures by waves and currents..
- Environmental Protection and Landscape Beautification:
- Ecological Restoration: gabion mattress can be used in ecological restoration projects, such as restoring natural rivers, wetland protection, etc., with good ecological compatibility.
- Landscape Design: Due to its natural and beautiful appearance, Renault pads can also be applied in landscape design as green walls, river landscapes, etc.
