What is U Channel Steel Support

U channel steel support is a passive support device with tensile strength, high compressive strength, and has good toughness properties, high supporting force, high supporting strength, can be used repeatedly, is widely used in mine roadway, especially in the deep complicated roadway and soft coal seam. 

U channel steel support optimal stress state is a rear wall after filling compacting pressure uniformly, as for rock pressure value u steel support reaches a certain value, the holder will have compressed, so that the surrounding rock acts on U pressure drop on the steel bracket, thus avoiding rock pressure is greater than the carrying capacity of u steel support bracket leaving destruction. 

According to site-specific circumstances, flexibility to select U channel steel support model, structure and shed from, the correct guidance of the stent construction tunnel u-shaped steel, to ensure its effective and reliable work, for speeding up the roadway excavation speed and reduce post-rework amount roadway, guarantee production safety, to extend the service life, get better technical and economic benefits, give full play to support the performance of the stent has important significance. Similar products are supporting miners, steel, U-shaped steel, light rail and other mine steel. 

U channel steel support with a scalable and reliable carrying capacity than other rigid support, adapt soft rock load and deformation section utilization, convenient support bracket back, a small amount of maintenance, support recovery reuse rate, reduce the pit wood use, environmental benefits are clear.
