Selection and specification:
According to the specific geological conditions, section size and support requirements of the roadway or tunnel, select the appropriate Tunnel Roof Support models and specifications.
Ensure that the material of the bracket meets the relevant standards to avoid the poor support effect caused by the use of poor-quality materials.
Installation and connection:
The installation of the bracket should be carried out in strict accordance with the construction drawings and operating procedures to ensure the verticality and horizontality of the bracket.
The connection between the brackets should be firm and reliable to avoid loose or falling off.
The lap length and connection method of the stent should meet the design requirements to ensure the overall stability of the stent.
Support timing:
The installation of the support should be carried out in time after the excavation of the roadway to avoid the instability of the surrounding rock caused by too long exposure time.
In the process of support, the deformation of surrounding rock should be closely watched, and the support programme should be adjusted in time.
Maintenance and management:
Regularly inspect and maintain the support to find and deal with potential hidden dangers in time.
No sundries should be piled up on the bracket so as not to affect its supporting effect.
For damaged or deformed brackets, they should be replaced or repaired in time.
Safety training:
Provide safety training to the operators to make them familiar with the installation, use and maintenance methods of the Steel Arch Support
Emphasise the safety operation procedures to avoid safety accidents caused by improper operation.
Environmental factors consideration:
In a harsh environment such as humidity and corrosion, additional anti-corrosion measures should be taken to extend the service life of the bracket.
In high or low temperature environments, attention should be paid to the thermal expansion or cold contraction phenomenon of the bracket material to avoid support failure as a result.
