U Channel

china coal 0001 U-channel Tunnel Steel Support Keywords: U-channel Steel Support, Tunnel Steel Support, Steel Support For Sale Introduction of U-channel Steel Support For Coal Mine U channel steel support cross section is shaped like the letter "U" in English. National production of u-shape cross-section shape, geometric parameters and material is different, at present China''''s production of u-shape model mainly include stepping, U25, U29, U36 these four. The stepping and U25 waist position; U29, U36 belongs to the ear. Stepping up the carrying capacity is very low, now rarely production. U channel steel support with high initial supporting force, supporting intensity big, easy to install and is not easy to deformation, so often used in the manufacture of roadway yielding metal stents, mine, mine roadway secondary supporting of roadway, and mountain tunnel support support purposes Use, effectively reduce the roof caving u-shape set, help such as accidents, safe and reliable, and enhances the stability of the mine ventilation system. Choose u-shape flexible support, better solved the difficult problem of the excavation support Structure of U-channel Steel Support For Coal Mine 1.Top Beam Top beam is circular arch, its amount depending on the cross section of roadway with different sizes, support force, transportation conditions, section 1 and section number. 2.Column leg There are three kinds of back leg , one kind is upside for circular arc form, for straight line at the bottom; The second is all for the curved shape, and only one radius of curvature; The third is all for the curved shape, but there are two curvature radius. Back leg in welding under the base, the base of large plate on the hard and soft; 3.Connection parts Fitting is a support section and internode card device, can the internode connection effect, can also be connected the two compression steel joint parts, provide pre-tightening force, make the u-shape between friction, thereby ensuring that the arch has a certain resistance and certain drop-off. 4.Rod between support Rod between support is to enhance the relative stability, the support bracket from longitudinal connection, form a whole. 5.Back-up material Back-up material is u-shaped steel support between supports and surrounding rock filling material, improve the stress of the support, to improve the bearing capacity and maintain the stability of surrounding rock. Characteristic of U-channel Steel Support For Coal Mine 1,Stand high pressure , support long time, easy to installation and not easy to be out of shape 2,compared with other rigid support , U-shaped steel support has a scalable and reliable carrying capacity to adapt to load and deformation of soft rock. 3,U-shaped steel support bracket support cross back high utilization convenient small amount of maintenance. 4,U3 steel support recycling reuse rate, reduce prop use, very obvious envir
