Features of Renault Mattresses

Renault Mattresses are a type of gabions, which is widely used in the modern construction of coastal fortifications, bridges, roads, to protect pipelines, as well as in landscape design. This article provides an overview of the technical characteristics of such structures, give advice on the choice of Matrants Renault to strengthen the slopes and other surfaces subject to landslide and erosion destruction.

Peculiarities

Renault Mattresses (Mattress Mattress Type of Gabions) are solid Mesh construction From the steel wire of double twist, filled with broken stone, rubble, pebbles or other similar materials.

The history of the use of gabion mattresses goes into the depths of the centuries: There is evidence that the first braided tanks stuffed with stones invented the Great Italian artist and the architect Leonardo da Vinci, first applying these facilities to strengthen the foundation of the Church. Later, the Gabions were actively used by the military as defensive means, saving soldiers from shells, and even later these designs were again entered into a peaceful life, helping to prevent the coast of blurring and saving people from flooding.

In the XIX century, the Italian company McCapferri applied Gabion Mattresses to strengthen the shores of the Reno River River, which is located near Bologna, after which it patented this type of construction.

Since then, such structures have been called Renault. Since then, this kind of gabion has been widely used to clamp river and sea coast, as well as to protect the marine and river bottom from erosion. Industrial Gabions manufactured in modern factories are box-shaped designs in the form of parallelepiped. They have a hard metal frame made of high-strength wire or steel rods welded in the form of a lattice. Inside the frame right at the construction site laid large stones, cobblestones, river pebbles or crushed stone.

The feature of Renault mattresses is their large compared to rectangular gabions. The base area and a small height is about 17-30 cm.

The advantages of gabion designs is Easy installation, long service life, relatively small construction costs, corrosion resistance and aggressive chemical impact. Renault mattresses are Beautiful drainage material, At the same time, not destroying and maintaining its initial characteristics during an unlimited period.

Specifications

Let us dwell in more detail on the design of Mattress Gabions. These Flat containers with a large reference area and shallow depth consist of a galvanized grid having a cellular structure.

Metal grid It is made of double twice wire, which has a special coating of Galmar, or lasting galvanizing due to which the mattresses Reno perfectly oppose corrosion. If it is assumed to use mattress gabions in an aggressive medium, after galvanizing or applying a special coating on steel wire wire, an additional layer of polyvinyl chloride is applied.

Such a shell protects the wire from chemical and mechanical damage.

Steel Mesh Cells in shape resemble bee honeycombs. The edges of such gabion structures are connected by wire with a large cross section than the wire of the mesh itself. Inside the container of the Gabion is divided Special diaphragms, That is, partitions located at a distance of 1 m from each other. With the help of such partitions, the best strength and stiffness of the design of mattress gabions Renault is achieved. In regulatory documents used by builders when strengthening the roadway, as well as coasts and slopes such structures are called Gabion-mesh mattress-mattress products and have standard sizes that correspond to GOST.

Such PDish gabions have a standard width that all rain mattresses are 2 meters – the width of the double mattress. The minimum thickness of such products is 0.17 m, there are also mattress gabions with a thickness of 0.23 and 0.3 m.

So strict uniform data of these parameters is dictated by the size of the hexagon mesh cells.

There is a variety Mattress Gabions of Increased Thickness entitled Gabions Jambo, Their height equals 0.5 m. Length Gabions Renault may vary within 3-6 m.

The weight of mattress gabions depends only on two indicators: lengths and thickness, since the width of the products is always the same. In addition, the weight of such structures affects the number of anti-corrosion coating layers. So, galvanized steel mesh Renault 2 m long, 0.17 m thick has weight 19.300 kg. The same galvanized steel wire, but already having an additional coating, weighs 24.700 kg. Mattress Renault 6 m long, the height of which is 0.3 m weighs 49 and 53 kg, respectively.

Where are applied?

As already mentioned, Mattress mattress designs use To strengthen the slopes and cones of bridges, during the construction of roads and pipelines, as well as as grounds for the sub-line of larger boxic gabions. Although the gabions are Renault and have a large surface plane, however, such structures are not suitable for the construction of high walls as an independent element, since due to a small thickness, such devices do not have sufficient rigidity.

Such planny products It is convenient to put on the bottom of the river, also on any uneven surfaces, as they are very plastic and easily take the form of relief. Renault mattresses are widely used To strengthen the bottom of the reservoirs and berelers, they are lined with landslide slopes.

Over time, the strength of the construction only increases, since the soil is applied inside such tanks, plants grumble there and strengthen its roots all the construction.

Gradually these Gabions become part of the landscape, At the same time, protecting it from water and wind erosion.

Instruction

All work on the installation of mattress gabions is conducted strictly in accordance With the technology of strengthening work. Before starting strengthening cones and slopes, it is necessary to remove the bulk soil and align and compact the platform with the help of special devices: vibration or vibration. Also, if necessary, it is worth removing stagnant on the surface of the water. Facing of slopes with the help of mesh mattress gabions is performed in stages.

  1. Mesh design lay out on Earth, thoroughly spilling all the folds.
  2. Vertical planes raise and connect with wire, keeping the perpendicularity of the faces.
  3. The resulting Renault mattress is installed on the place intended for it and connect with the wire with adjacent blocks.
  4. Lay inside the mesh box filler, which are usually large wreckage of solid rocks, such as granite, by a third of the volume. Stileks for the magnitude of the stones to 40-200 mm.
  5. The opposite sides of the Gabion connect with special brackets by a twist.
  6. Continue filling capacity with an excess of 3-5 cm.
  7. Close the mesh metal capacitance as the same lid, firmly tied it with wire to side faces.

During operation is carried out Regular inspections such structures, Destroyed blocks are repaired (Sleep the filling material, change whole modules, watered landscaped slopes in the absence of rains, especially in the first years after editing). Renault mattresses choose when it is required to strengthen large areas. Depending on the task, the mattress gabions of one or another length and thickness are chosen. The filler material is also very important and depends on specific purposes.

It is necessary to monitor that the size of its elements exceeds the size of the wire mesh cell.
