1. The U-shaped steel bracket is ingeniously designed to achieve an optimal stress state. By filling and compacting the pipe wall, uniform pressurization is achieved. Unlike other rigid supports, U-shaped steel supports offer retractability and reliability. They adapt seamlessly to the load and deformation of soft surrounding rock, boast a high utilization rate of section, facilitate convenient support installation, and require minimal maintenance. Additionally, they have a high recycling rate, reducing the use of pit materials and providing evident environmental benefits.
2. Key characteristics of the U-shaped steel bracket for mining include enduring long-term pressure, providing consistent support, and easy assembly with minimal need for replacements.
3. The U-shaped steel support has demonstrated exceptional results at mining roadway bifurcation points, gaining favor in the mining machinery industry. Its design aims to achieve an optimal stress state, ensuring the pipe wall is uniformly compressed after filling and compaction. Upon installation, the U-shaped assembly withstands surrounding rock pressure, alleviates external pressure, and mitigates operational risks. Noteworthy are its high resistance to deformation under intense pressure, prolonged support duration, and straightforward installation process.
