1. The innovative design of the U-shaped steel bracket, known as the 'U-shaped assembly,' is ingeniously crafted to achieve an optimal stress state. Once the pipe wall is filled and compacted, it experiences uniform pressurization. Compared to other rigid supports, U-shaped steel brackets boast several outstanding features: retractable ability, enhanced reliability, and adaptability to the loads and deformations of soft surrounding rock. They offer a high utilization rate of the section, convenient support return, minimal maintenance, and an impressive recycling rate. Moreover, they significantly reduce the use of pit materials, delivering clear environmental benefits.
2. The U-shaped steel bracket for mining is distinguished by its primary characteristics: durability under pressure, long-term support capability, and ease of assembly without the need for frequent replacement.
3. The application of the U-shaped steel support in mining roadway bifurcation points has yielded remarkable results, earning high praise from the mining machinery industry. The U-shaped assembly is designed to achieve an optimal stress state, ensuring that the pipe wall is uniformly compressed after filling and compaction. At any given time, the U-shaped assembly can handle the pressure of the surrounding rock, providing robust support while relieving external pressure and reducing operational risks. Notably, the U-shaped steel bracket performs under high pressure, offers prolonged support, is easy to install, and resists deformation.
