Reno Mattresses are thin flexible cages (less than 500mm thick), made of hexagonal double twisted woven wire mesh. The Mattress is divided into cells by internal diaphragms/partitions positioned at 1 m centres to limit rock fill movement during high flow conditions.
Material of Reno Mattresses
The metaril wire is usually with zinc coated which is meet or exceed the requirements of ASTM A475-89, and can either be Galfan (95% Zinc 5% Aluminium Mischmetal Alloy) coated mild steel or Galfan coated with an additional PVC coating if required. Galfan has significantly improved corrosion resistance to zinc in both chemical and physical terms. This technology when applied to steel wire products provides up to about three times greater protection per unit coating mass, than do zinc coatings. PVC coated units are recommended in River or fluvial conditions where abrasive sediments may exist, marine conditions, mining applications, where soil is highly acidic or alkalinic or where an extended design life is required.
All the physical and mechanical properties of Reno mattresses meet or exceed the requirements of ASTM A975-97.
Use of Reno Mattresses
Reno mattresses are used for river bank and scour protection, channel linings for erosion control, and embankment stability. They are filled with rock at the project site to form flexible, permeable, monolithic structures to promote rapid growth of natural vegetation. The base section of the Reno mattress is divided into compartments and filled with stones at the project site. With lids secured, Reno mattresses form flexible, permeable, monolithic structures.
Advantages of Reno mattresses:
1)Flexibility The woven mesh system has the capability of withstanding unexpected and/or localized stresses due to ground settlements and scour by deflection while maintaining its structural integrity.
2)Permeability The stone fill allows the water to seep through the structure while retaining the soil, therefore no additional drainage is required to relieve the hydrostatic pressures.
3)Cost Effective, Easy to Build Reno mattress construction does not require skilled labor because they are very easy to build. Standard construction equipment can be used. Structures can be built in stages, if necessary, and baskets can be prefilled and launched to enable the installation under water.
|The C-Rings are made of high tensile strength “ZincAl” coated steel wire or Stainless Steel Wire. Stainless Steel C-Rings are used for PVC coated gabion Structures. The C-Rings are supplied in boxes of requested quantities||The "Permathene U Clip" is used to connect gabion panels to make a cage. It is used for decorative gabions. The U Clip is secured by using a special tool available for purchase or hire. Alternatively they can be fastened using needle nosed pliers.|
|Gabion Pins are used to join cages together. Simply place one empty cage against another empty cage and mesh together the end spirals. The pin is easily pushed down between the coils which will lock the cage in place.||Gabion stiffener. These are used to reinforce gabion cages, they are placed in every corner. Supplied in singles.Wire made from Galfan (5% Aluminium, 95% Zinc).3.4mm diameter wire x 450mm (L).|
|These spirals are used to join multiple cages if preferred over pins. They are also used for joining stacked cages. For example: If you have a 2m long x .5m wide x .5m high cage stacked on top of a 2m long x 1m wide x 1m high cage you must connect the upper cage to the bottom cage.||A pneumatic gun will greatly improve efficiency on any gabion project. It is used with overlapping fasteners.|
Gabions are supplied in bags, folded.
| ||2. Spread the gabion on a hard, flat surface and flatten the folds of all make sure that all parts of the gabion and smooth bends and no irregularities.|
| ||3. Bend the front, rear and side panels in a vertical position, forming a rectangular box. Connect the top corners of the box with a thick wire edges sticking out of the corners of each panel. Make sure that the upper parts of all four sides of the box are on the same level.|
|4. Begin to associate the top corners of panels for a bunch of wires, connecting the panels together coils, as shown in riunke. Ligation produced by alternating one loop and two loops through 100 mm.|| |
Formation of Gabions Constrvction
|5. Generate a few empty gabions and set them into position. In the corners should drive rods and tighten them well. While the gabions are empty, they should make a bunch of them already filled with established and gabions. The surface of the land on which the rehydrating gabions, should be planned. To front edge gabion was flat, with its outer side is attached erevyannuyu frame. Between the gabions are bound, as shown in the figure. The second row of gabions shall be as follows: back to back, face to face.|
6. To fill the gabions used stone-aggregate size of 125-200 mm (but not exceeding 250 mm). The minimum size of stone should not be less than the grid size. Intrusion of 5-7% smaller stone, which should be in the central part of the gabion.
|7. Gabions are filled manually or mechanically. Make sure that the stones fit tightly between them is the minimum number of voids. Last gabion left blank, to be able to bind to him the following set gabions.|
| ||8. For once filled only 1 / 3 gabion. Then fix the gabion from within the horizontal band of the surface layer of the stone. Then fix toruyu third gabion, and, finally, his last one-third to the top. Gabions filled with half-meter in two steps. Reno Mattress thickness 170, 230, 300 mm filled at once, without connecting clips.|
|9. Gabion filled with stones at 2.5-5 cm above the top of lumps for precipitation of the stone. For these purposes, the most suitable material fines. When laying gabion mattresses (mattress Reno) in the downstream of dams and installation of simple aprons for protection against erosion sites are not active influence of the incident jet or strong flow between the upper lid gabion (Reno mattress), and his head to set additional binder clips.|| |
| ||10. Gabion lid must be pull tightly to the upper bound gabion and simultaneously link the wire. First you need to do temporary (provisional) to bind angles, to prevent any shift mesh around the perimeter of the top of the gabion. if rock-solid filler prevents cover a draw, then some of its number can be moved to central part of the gabion.|
Attaching the Gabion
To install the gabions, the following tools:
Pliers, preferably with long lips
Mount or small scrap
A special tool to pull the cover and link gabion.
|11. In some cases (for a relatively extended structures, which assumes a large load) for each installed gabion tension, together with a simple device to apply tension winch. The winch is securely anchored and secured to the sidewall of the empty gabion, the other side plate which is securely attached to an already worthwhile elements. Next gabion immediately|
