The retractable steel support of the roadway has the advantages of high initial supporting force, large support strength, easy installation, and difficult to deform. Therefore, it is often used to manufacture the retractable metal support of the roadway, used as the mine roadway, the secondary support of the mine roadway, and the mountain tunnel Support and other uses. The use of the U-shaped roadway retractable protective steel support can effectively reduce the occurrence of accidents such as roof fall and sheet ganging, which is safe and reliable and improves the stability of the mine ventilation system. The use of U-shaped steel retractable support brackets can effectively reduce the occurrence of accidents such as roof fall and chipping, which is safe and reliable, and improves the stability of the mine ventilation system. U-shaped steel support is used to better solve the problem of tunnel support.
Retractable U-shaped protective steel support
1. The retractable steel support of the roadway bears large pressure, long support time, and has the characteristics of easy installation and deformation.
2. The retractable protective steel support of the roadway is more shrinkable than other rigid supports and has a stable and reliable bearing capacity to adapt to the load and deformation of soft surrounding rocks.
3, the laneway is deflatable, the support bracket section is highly utilized, and the support bracket is easy to maintain and the amount of maintenance is small.
4.The retractable protective steel support of the roadway has a high recycling rate, which reduces the use of pit wood, and the environmental protection benefit is very obvious.
