The main features of the steel arch support are: high pressure, long supporting time, easy installation and easy deformation. It is mainly used for the support of mine tunnel, which has the ability of yielding, stable and reliable bearing and can adapt to the load and deformation of soft surrounding rock.
The application of the semicircle arch support of u-shaped steel straight wall to the bifurcating point of mining roadway has made remarkable achievements and the selection of the u-shaped steel arch support can be reduced to solve the difficult problem of tunneling support. Compared with other rigid supports, u-shaped steel arch has a flexible, stable and reliable bearing capacity, ADAPTS to the load and deformation of soft surrounding rock, has a high utilization rate of section, easy support and back, small maintenance amount, high reuse rate of support recovery, and reduces the use of pit wood, which has obvious environmental benefits.
Main use of u-shaped steel support: it is mainly used for secondary support of mine roadway, mine roadway and support of tunnel through mountain.
