1. The U-shaped steel bracket is ingeniously designed to offer an optimal stress state. Once the pipe wall is filled and compacted, the pressure distribution becomes uniform. Unlike other rigid supports, U-shaped steel supports excel with their retractability and reliability, adeptly adapting to the load and deformation of soft surrounding rock. They boast a high utilization rate of section, convenient support return, minimal maintenance, and an impressive recycling rate. This reduces the consumption of pit materials, yielding significant environmental benefits.
2. The primary characteristics of U-shaped steel brackets for mining include their excellent pressure resistance, prolonged support duration, and ease of assembly. They are notably durable and require infrequent replacement.
3. The application of U-shaped steel supports at mining roadway bifurcation points has delivered outstanding results, earning widespread acclaim in the mining machinery industry. The design is intended to achieve an optimal stress state, ensuring uniform compression of the pipe wall after filling and compacting. This allows the support to generate pressure in response to the surrounding rock's stress at any given moment, effectively relieving external pressure and mitigating mining operation risks. U-shaped steel brackets are characterized by their high pressure tolerance, extended support time, and straightforward installation, with minimal deformation.
