The steel arch support is the framework that supports and protects the equipment or the main body of the steel structure. There are also some for the convenience of the operator up and down and set up.
Steel support is a kind of passive support for coal mine support, with high tensile strength and compressive strength, as well as good toughness performance, high supporting force and large support strength. Steel arch support can be used for many times and is widely used in u-lane of mine, especially in deep complex roadway and soft coal seam roadway. The composition of the steel support: the bottom corner plate of the three sections of U section is composed of four karan side shed parts. Steel support is mainly used for secondary support of mine roadway and mine roadway through mountain tunnel.
The stress state of the steel arch support is that after the wall is filled and compacted, it is uniformly compressed. When the surrounding rock pressure value on the u-shaped steel support reaches a certain value, the support will produce compression, so that the pressure of surrounding rock acting on the u-shaped steel support will drop, so as to avoid the failure of the support caused by the surrounding rock pressure greater than the bearing capacity of the u-shaped steel support.
