Steel Grid
Surface coating systems are installed to top anchorages built at the top of the slope and the load is borne by the top steel cable. Bearing blocks that carry risk of falling with lateral and horizontal reinforcements in places where pure Steel Grid material is insufficient through calculations is among the alternatives provided by our company.
Steel grids (steel wire mesh) or specially designed rock barriers are used in highways, railroads, municipalities and administrations against rock falls. Steel grid to be used (twisted pair hexagonal produced wire mesh) can be combined with special anchorage systems according to surface structure to achieve solution.
Here, the goal is to attain sufficient level of safety against rock falls. Upon calculation of the loads on the anchorages in relation to the subject, relevant pore size and wire thickness is decided. Barriers slightly differ and barriers can be selected based on possible rock fall routes, according to energy level, bouncing height and speed.
One of the methods employed in construction and maintenance of fissures in road, railroad and HPP projects to ensure slope stability by preventing breaking off loose rocks and debris is twisted pair hexagonal pored steel grid use. With this method, unstable large pieces are held in place while slope stability is increased in time with the plants growing in the pores.
Main properties of steel grid to be used are:
◦ Steel Grids do not get loose, splinter easily and do not release rocks, stones and debris the compress.
◦ Galvanized wires are resistant to rust and have long life (30 years)
◦ They are flexible and easy to install
Supplied in 25 m or 50 m rolls for convenience to carry and lay, rolls can be as wide as 4 meters. Despite the necessity to carry by air with helicopters in very special cases, when fixed with special anchorage at the top of the slope and released down rolls are woven together with cables of same or higher quality. Reinforcement of Steel Grids with Steel Cables; product obtained by reinforcing Steel Meshes (Steel Grid) with cables is called Steel Composite Grid. Reinforcing the system with strength increasing 8.00 mm steel cables on the surface and connection points following Steel Grid application will increase the load bearing capacity of the system. Steel cables with 1770 N/mm2 strength to be used will hold blocks larger than what steel grid can bear together. Additionally, overlapping adjacent rolls and weaving them with cables will remove the risk of opening from joints. Surface anchorage planned to be used shall be operated with current woven steel cables enabling cables to be supported by surface anchorages. However, in sections where the surface is not massive, no surface anchorage shall be used.
