In the support of mines and tunnels, products such as supports arch have become more and more popular. By connecting them, a system of load-bearing structures is formed to enhance the great support effect. The support arch itself has huge advantages, the rigidity has been improved by more than 70 times, and the bending resistance of the cross section is strong, which has been improved by nearly 40 times. The use of support arch retractable support better solves the problem of tunneling support.
Support arch product features
1. The support arch bears high pressure, long support time, and has the characteristics of easy installation and deformation.
2. Compared with other rigid supports, support arch have shrinkage, stable and reliable bearing capacity, and can adapt to the load and deformation of soft surrounding rocks.
3. The support arch has a high cross-section utilization rate, the bracket can be conveniently returned, and the maintenance amount is small.
4. The support arch has high recycling and reuse rate, reducing the use of pit wood, and the environmental protection benefits are very obvious. The use of support arch can effectively reduce the occurrence of roofing and flank accidents, is safe and reliable, and improves the stability of the mine ventilation system.
In the coal mine industry, support arch equipment has always been a ‘safeguard’ for the production safety of the coal mine industry. In recent years, the deep foundation engineering of support arch has been increasing day by day, and more and more support personnel have begun to pay attention to the superiority of arch support performance.
