Introduction Of 25 U Shaped Support Mining Tunnel Steel Support Bracket Steel Support
U-shaped steel support is a cross-sectional shape like the English letter "U" steel. States produced sectional shape of U-shaped, etc. geometric parameters and material vary. U25 steel support with high initial support force, supporting strength, easy to install, easy to deformation, etc., so commonly used in the manufacture of roadway retractable metal stents for mine tunnel, mine tunnel secondary support, as well as the support of branch tunnel through the mountain care and other purposes.
Characteristic
25U shaped steel support could effectively reduce the cave, spalling and other accidents, safety and reliability, improved stability of the mine ventilation system and other notable features. Optional retractable U-shaped steel bracket, solves the problem of tunneling support. Widely used in mine tunnel, mine tunnel secondary support, as well as support through the mountain tunnel support and so on. 25U shaped steel support due to withstand pressure, support long time, easy to install easily deformed and very popular in the majority of mining machinery industry
Application
1,25 U-shaped steel support with high withstand pressure, support long time, are easy to install easy deformation characteristics.
2,25 U-shaped steel support than other rigid support with a scalable and reliable carrying capacity to adapt to the load and deformation of soft rock.
3,25 U-shaped steel support cross utilization is high, easy to stand back support small amount of maintenance.
4,25 U support with high recycling reuse rate, reduce prop use, environmental benefits are clear. The project is safe and reliable, effectively reduce the cave, spalling and other accidents, improve mine ventilation system stability.
The project is to promote applied research, improve mine safety production conditions, reduce production costs, in line with national policy with steel and wood, with good social and economic benefits and environmental benefits.
