1. The design of the U-shaped steel bracket, often referred to as the 'U-shaped assembly,' is specifically engineered to achieve an optimal stress state. Once the pipe wall is filled and compacted, it applies uniform pressure. Compared to other rigid supports, U-shaped steel supports boast several advantages, including retractable capability, exceptional reliability, and adaptability to the load and deformation of soft surrounding rock. They offer high sectional utilization, easy support retrieval, minimal maintenance, and a high recycling rate, reducing the use of pit materials while providing significant environmental benefits.
2. The primary characteristics of U-shaped steel brackets for mining include sustained pressure support, long-lasting durability, and ease of assembly. These brackets are designed to hold under pressure for extended periods without the need for frequent replacement.
3. U-shaped steel supports have demonstrated outstanding performance, especially at roadway bifurcation points in mining applications, earning widespread acclaim within the mining machinery industry. The 'U' shaped assembly is crafted to achieve an optimal stress state, ensuring the pipe wall is uniformly compressed after filling and compaction. At specific times, when the surrounding rock exerts pressure, the U-shaped assembly provides robust support, alleviating external pressure and mitigating operational risks. These supports are resilient under high pressure, offer prolonged support durations, and are easy to install without significant deformation.
