Scope of application:
Support Arch is mainly used in the construction of roadway with soft surrounding rock and large ground pressure, such as coal mine, metal mine and other underground mining environment.
Commonly used Support Arch shapes include semicircular arch, three-centered arch and trapezoidal, etc., in order to adapt to the needs of different roadway sections.
Material preparation and inspection:
The material, specification, strength as well as processing of the bracket and its accessories (such as card cables, bolts, tie rods, etc.) must be in accordance with the design and relevant standards.
Maintenance of Steel Arch Support
Appearance check:
Regularly check the appearance of Steel Arch Support to see whether there is obvious deformation, cracks, rust or corrosion.
If abnormalities are found, the damaged bracket parts should be repaired or replaced in time.
Connection parts inspection:
Focus on checking the connection parts of the bracket, such as whether the bolts, card cables and other fasteners are loose or damaged.
Loose or damaged fasteners should be tightened or replaced in time to ensure the stability of the bracket.
Anti-corrosion treatment:
After the rust removal treatment is completed, the stent should be anticorrosive painted.
Choose suitable anticorrosion coatings and paint according to the specified painting process to ensure that the coating is even and without leakage.
