Gabion box used for retaining wall construction and sea shore protection

Gabion box is three dimensional structures made of metal mesh double twisting, filled with stone (double twist wire mesh ensures the integrity, strength and uniformity of load distribution and prevents unwinding in case of rupture of the grid). These designs are divided into sections by means of diaphragms mounted inside the gabions every meter in length. To reduce the cost for installation of gabion structures using gabions box-large size - the so-called gabions Jumbo. They have a length from 3 to 6 meters at a height of 0.5 m. Standard wire diameter - 2.7 mm, the diameter of the wire edges (to enhance the framework gabion) - 3.4 mm. Cell depending on the purpose of gabion size 8x10 cm and 6x8 cm size gabion may be arbitrary, but must take into account the stability of the gabion structures, which will be greater, the greater the gabions at the bottom.

Wire mesh used for gabions, made of galvanized steel wire or solid wire coated galfan. In the case when the gabions are used in hostile environments, the wire galvanizing or coating galfan before coated PVC can provide greater resistance to chemical, mechanical and corrosion damage. Gabions are filled with any stone material surpassing the size of the diameter of the grid cell. It can be rock, gravel, quarry, stone fraction of 100-300 mm. The selected material must weigh all the relevant characteristics of the static and functional requirements of buildings erected and its service life.

Over time, the space between the stones are filled with dust, mud or dirt, which promotes plant growth. Therefore, merging with the natural environment, gabions become part of the natural landscape. In addition, the accumulation of soil particles increases the strength properties of the structure, acting as a binder.

Gabions are mainly used for construction of retaining walls, building of embankments of roads and railways, river and sea shore protection, landscaping, stabilization of soil erosion and conservation of soil. Due to very good hydraulic characteristics are used for shore protection of rivers, construction of weirs and dams. Gabions with PVC coating used to protect the coasts.

Box-shaped gabions in the world have been used for over 100 years. For the first time as a reinforcing material of construction gabions have been used in France in the early 19th century. It is noteworthy that these early structures are functioning properly until today. Gabion can be used to reinforce slopes, hillsides, embankments, cuttings, gullies, road-bridge structures. In some areas, gabion structures, until recently, had limited application and used only to strengthen the embankment slopes. Experience shows that the construction of gabions is an alternative way to protect road-bridge slopes.

The use of gabion structures is a highly effective and versatile way to not only strengthen the slopes, but also enhance, stabilize and protect the exploited subgrade, bridge supports, regulatory dams, coastal, and other structures. Performing protective functions of fortification, gabion structures can serve as a reverse filter, and in some cases they can be used to provide impervious events.

Currently known and widely used for more than 20 types of building slopes: grass cultivation, planting shrubs, planting, thermal protector and protective layers using geotextiles, prefabricated concrete lattice, clay soils, surface and solid lattice, flexible concrete slabs, prefabricated reinforced flexible grid, precast concrete and reinforced concrete slabs, monolithic reinforced concrete slabs, riprap, and others.
