The characteristics of U29 u-shaped steel support are the reasons why people choose the shed support:
Compared with other rigid supports, U29 u-shaped steel supports have flexible, stable and reliable bearing capacity to adapt to the load and deformation of soft surrounding rocks.
Second, the environmental benefit of U29 type U - shaped steel support makes people choose shed support for many times.
U29 U - section steel support section high utilization rate, easy support, small maintenance. High reuse rate of support recycling, reduce the use of pit wood, environmental benefits are very obvious.
New type U29 is u-shape set modified magnesium cement as cementitious material, supplemented by need of filling material, take the reinforced material of glass fiber, bamboo bar, is the extractive industries, especially in the coal industry emerging generation of wood material, it calls to protect and save the use of timber in our country, greatly alleviate the resources of forest and timber in our country, the contradiction of the growing demand for mine roadway can be widely used in mining industry and buttress the support of the eye.
The U29 u-shaped steel support is mainly used for the secondary support of mine roadway, mine roadway, and the support support of the tunnel through the mountain. The use of shed support can effectively reduce the occurrence of roof caving and sheeting accidents, which is safe and reliable and improves the stability of mine ventilation system. The selection of shed support can be used to solve the problem of tunneling support.
