I. Construction preparation
Material preparation: Make sure the material, specification and strength of Steel Mine Supports and its accessories (such as connecting plate, bolts, tie rods, etc.) are in accordance with the design and relevant standards.
Check the materials: before construction, the Steel Mine Supports and its accessories should be fully inspected to ensure that there is no crack, no corrosion, no oxides or dissolved slag and other obstructions.
Construction platform erection: a solid working platform should be erected at the construction place, and the standing legs of the platform should be placed on the hard bottom and set firmly.
Second, the construction process
Bracket installation:
The legs of the stent should fall on the solid bottom, and the gap between the stent and the top and the gang must be stuffed tightly and backed solidly.
Firm braces or ties should be set up between the stents to ensure the stability of the overall structure.
When erecting the bracket, the legs should be planted first and held steady, in turn, from the two gangs will be Tunnel Roof Support each section of the lap tightly stuck firmly, the fastening screws should be tightened.
Construction cooperation:When erecting the bracket, the personnel before and after should coordinate and cooperate to avoid the bracket crooked or falling and causing injury.Construction personnel must wear safety belts when working at high places and make sure that the safety belts are fixed on a stable structure.
Safety measures:Specialized personnel should be appointed to be responsible for the work at the construction site, with a clear division of labor and precautions.In the section with serious roof deformation, temporary support measures such as adding wooden point columns should be taken to ensure safety before carrying out the scaffolding construction.
Third, check and maintenance after construction
Stent inspection:After the construction is completed, the stent should be fully inspected to ensure that the stent has no deformation, no loosening, and the connection is tight and reliable.
Maintenance measures: Inspect and maintain the stent regularly, and replace or repair the stent in time when cracks, corrosion and other problems are found.
Records and reports: Establish the construction and maintenance records of the stent, record the information of the stent's model, quantity, installation location, inspection time, maintenance situation and so on, so as to facilitate the follow-up management and maintenance.
