Compared with other rigid supports, Steel Arch Support has the advantages of strong bearing capacity, good stability, good shrinkability, adaptability to load and deformation of soft surrounding rock, high utilization of section, convenient support for support, and small maintenance. The scaffold has a high recycling rate and reduces the use of pit wood, and the environmental protection benefits are very obvious.
Steel Arch Support is a kind of passive support for coal mine support. It has high tensile strength and compressive strength, good toughness, high support force, high support strength and can be used repeatedly. It is widely used. In the mine U Lane, especially in deep complex roadways and soft coal seam roadways.
Steel Arch Support Product Features
Steel Arch Support is under pressure, supports for a long time, and is easy to install and not easily deformed.
Steel Arch Support has a retractable and stable load carrying capacity compared to other rigid supports, adapting to the load and deformation of soft surrounding rock.
Steel Arch Support has a high utilization rate, convenient support for the support, and low maintenance.
Steel Arch Support has a high recycling rate and reduces the use of pit wood. The environmental benefits are obvious.
The stress state of Steel Arch Support is that after the wall is filled and compacted, it is evenly pressed. When the pressure value of the surrounding rock on the u-shaped steel bracket reaches a certain value, the bracket will compress and the surrounding rock acts on the U-shaped steel bracket. The pressure on the upper part is lowered, so that the surrounding rock pressure is prevented from being greater than the bearing capacity of the u-shaped steel support and the support is broken.
