Steel mine supports have single-section beams, double-section beams, three-section beams, and attached ground beams. They have the characteristics of high pressure, long support time, easy installation and deformation, etc. They are the main types of steel for steel tunnel sheds.
The cross section of U-shaped steel mine support looks like the English letter "U", and sometimes also the shape of the Japanese letter "ひ". It is the main type of steel for making the roadway scalable U-shaped steel support. Support and secondary support for mine tunnels are widely used. Due to the inconsistent performance and use of U-shaped steel stent brackets in different countries, U-shaped steel stent brackets in different countries will be more or less different. The utilization ratio of steel mine support sections is high, the support is easy to support, and the amount of maintenance is small; U-shaped steel mine supports Compared with other supporting materials, the mine support has a high recycling rate and reduces the use of pit wood, which has obvious environmental benefits.
U-shaped steel mine supports have the advantages of high initial supporting force, large support strength, easy installation, and non-deformation. Therefore, they are often used to manufacture scalable metal supports as support and support for mine tunnels, mountain tunnels, and water tunnels; The material is: 20Mnk.
