1. The U-shaped steel bracket design is ingeniously crafted to achieve an optimal stress state. Upon filling and compacting the pipe wall, it becomes uniformly pressurized. Distinguished from other rigid supports, U-shaped steel supports boast retractability and reliability, seamlessly adapting to soft surrounding rock's load and deformation. This design ensures high section utilization, convenient support restoration, minimal maintenance, and high recyclability. Furthermore, it significantly reduces the use of pit materials, providing notable environmental benefits.
2. U-shaped steel brackets for mining feature several key characteristics: they maintain prolonged support under pressure, are easy to assemble, and require minimal replacements.
3. U-shaped steel supports have proven highly effective at mining roadway bifurcation points, earning widespread acclaim in the mining machinery industry. The design ensures a balanced stress state where the pipe wall is uniformly compressed after filling and compaction. When the U-shaped assembly is installed, it can manage the pressure value of the surrounding rock, producing pressure to relieve external stress and mitigate mining risks. These supports excel under high pressure, provide long-lasting support, and are easily installed without deformation.
