I. Appearance check
Regularly check the appearance of the Tunnel Roof Support to see if there is any obvious deformation, cracks, rust or corrosion. These phenomena may indicate that the bracket structure has been damaged, and need to be repaired or replaced in time.
Second, connecting parts inspection
Focus on checking the connection parts of Tunnel Roof Support, such as bolts, card cables and other fasteners are loose or damaged. Loose or damaged fasteners will affect the stability and safety of the bracket structure and should be tightened or replaced in time.
Third, cleaning and rust removal
Regularly clean the dust, dirt and debris on the surface of the Underground Roof Support and keep its surface clean and dry. This helps to reduce the occurrence of corrosion and rust.
For the Underground Roof Support that has been rusted, it should be descaled in time. Mechanical descaling, chemical descaling or sandblasting descaling can be used to remove the rust and corrosion completely.
Fourth, anticorrosion treatment
After the rust removal process is completed, the Underground Roof Support should be anticorrosive paint treatment. Select the appropriate anti-corrosion coating, according to the provisions of the painting process for painting, to ensure that the coating is uniform, no leakage.
Regularly check the integrity and adhesion of the anticorrosion coating, if the coating is found to be damaged or peeled off, it should be repaired or repainted in time.
V. Reinforcement treatment
For the existence of safety hazards of Underground Roof Support, such as serious deformation, insufficient bearing capacity, etc., should be promptly reinforced treatment. Can be used to increase the support rod, replacement of high-strength fasteners and other methods to improve the stability of the bracket structure and load-bearing capacity.
Sixth, repair treatment
For the Tunnel Roof Support components have been damaged, such as fracture, cracks, etc., should be repaired in a timely manner. Repair should be in accordance with the design requirements for welding, replacement or reinforcement and other operations to ensure that the repaired bracket structure meets the safety requirements.
