1. The innovative design of the U-shaped steel bracket, specifically the 'U-shaped' U-shaped assembly, ensures an enhanced stress state. Once the pipe wall is filled and compacted, pressure is uniformly distributed. Unlike other rigid supports, U-shaped steel supports boast superior retractable ability and reliability, efficiently adapting to the load and deformation of soft surrounding rock. These brackets offer a high section utilization rate, facilitate convenient support installation, require minimal maintenance, and have an excellent recycling rate. Additionally, they significantly reduce the use of pit materials, providing remarkable environmental benefits.
2. Main characteristics of the U-shaped steel bracket for mining include its ability to withstand substantial pressure, maintain support points for extended periods, and facilitate easy assembly without frequent replacements.
3. The application of U-shaped steel supports at mining roadway bifurcation points has yielded outstanding results, earning widespread approval in the mining machinery industry. The 'U' shaped U-shaped assembly is designed to achieve an optimal stress state, ensuring uniform compression of the pipe wall post-filling and compaction. At a specific point in time, the support can respond to surrounding rock pressure by generating counter-pressure, alleviating external stress, and mitigating operational risks. These U-shaped steel brackets excel under high pressure, provide prolonged support, and are easy to install without significant deformation.
