The main characteristics of U29 steel arch support: bear pressure, support for a long time, easy to install, not easy to deformation and so on.
I believe you are familiar with tunnel roof support, but I don't know if you have heard of U29 steel arch support. U29 steel support is also a kind of steel support. What's the difference? Let's introduce the characteristics of U29 steel arch support.
Main uses of U29 underground roof support: it is mainly used for mine roadway, secondary support of mine roadway and support of mountain crossing tunnel.
1. It has the characteristics of large pressure, long support time, easy installation and not easy deformation.
2. Compared with other rigid supports, it has retractability, stable and reliable bearing capacity and adapts to the load and deformation of soft surrounding rock.
3. The utility ratio of the cross section is high, the support is easy to support and the maintenance is small.
4. Tunnel roof support recycling rate is high, reduce the use of pit wood, environmental protection benefit is very obvious.
