1. The ingenious design of the U-shaped steel bracket, specifically the 'U-shaped' assembly, is meticulously crafted to achieve an optimal stress state. Upon filling and compacting the pipe wall, it ensures uniform pressurization. Unlike other rigid supports, U-shaped steel supports offer remarkable retractability and reliability. They adapt seamlessly to the load and deformation of soft surrounding rock, boast a high utilization rate of sections, and make support backs convenient with minimal maintenance. Additionally, their high recycling rate significantly reduces the need for pit materials, presenting clear environmental benefits.
2. U-shaped steel brackets for mining exhibit outstanding characteristics: they can withstand high pressures, maintain long-term support at critical points, and are designed for easy assembly, making replacements a rare necessity. These attributes underscore their superior performance and practicality in mining operations.
3. The application of U-shaped steel supports at mining roadway bifurcation points has delivered impressive results and gained widespread acclaim in the mining machinery industry. The 'U-shaped' assembly is designed to achieve an ideal stress state, ensuring the pipe wall is evenly compressed after filling and compacting. When installed, the support effectively handles the pressure from the surrounding rock, alleviates external stress, and mitigates operational risks. These brackets, renowned for their durability under high pressure, extended support duration, and ease of installation, resist deformation, making them indispensable in mining operations.
