1. The innovative design of the U-shaped steel bracket, known as the 'U-shaped' assembly, aims to attain an optimal stress state. Upon filling and compacting the pipe wall, it achieves uniform pressurization. Compared to other rigid supports, U-shaped steel brackets boast retractable ability, reliability, and adaptability to the load and deformation of soft surrounding rock. They offer high sectional utilization, easy support installation, minimal maintenance, and a high recycling rate, significantly reducing the use of pit materials and providing substantial environmental benefits.
2. U-shaped steel brackets for mining are distinguished by their main characteristics: enduring pressure, long-lasting support points, and easy assembly, making them difficult to replace.
3. The application of U-shaped steel supports in mining roadway bifurcation points has yielded remarkable results, earning favor within the mining machinery industry. The 'U' shaped assembly is designed to achieve an optimal stress state, ensuring uniform pipe wall compression after filling and compaction. When the U-shaped assembly is installed under the pressure of surrounding rock, it generates support pressure, alleviates external stress, and minimizes operational risk. These brackets withstand high pressure, provide long-term support, and are easily installed without deformation.
