The verticality and torsional inclination of qualified 25U steel archs meet the standards. So how to detect the verticality and torsion slope of the U steel arch? I have compiled some materials for everyone to study together.

Check the perpendicularity and torsion inclination of the support, and adjust it when it exceeds the allowable error range stipulated in the quality standard. According to the horizontal spacing between the vertical line laid down in the middle of the top beam and the connecting line between the two column feet, you can know whether the support is vertical or not, and whether the support is twisted or not according to the roadway centerline and the connecting line between the two columns.

U-shaped steel support, as a support, has certain significance for the support of coal mine roadway. Therefore, the quality of 25U steel arch cannot be neglected.

1. the 25U section steel bracket bears great pressure, has long supporting time, and is easy to install and not easy to deform.

2. Compared with other rigid supports, 25U steel arch have contractibility, stable and reliable bearing capacity, and adapt to the load and deformation of soft surrounding rock.

3. The section utilization rate of 25U steel arch is high, the support is convenient to support and the maintenance amount is small.

4. The recovery and reuse rate of 25U steel arch is high, which reduces the use of pit timber and has obvious environmental benefits. This project is safe and reliable, which effectively reduces the accidents such as roof fall and side fall, and improves the stability of mine ventilation system.
