It is solidifying.
Step 4：Anchoring construction, operating personnel are carried out the construction of anchor hole using anchoring drilling machine 3, are used cooperatively after pore-forming
Resin anchoring agent installs high strength steel strand anchor cable, configures special-shaped high intensity arch tray, installs aligning ball pad additional, and in drilling
Slip casting aluminium-plastic pipe is inserted into, using cotton yarn and double slurries sealing of holes, by slip casting aluminium-plastic pipe to anchor cable hole slip casting, after the completion of slip casting, and
Carry out Hou Ning.
Step 5：Anchorage cable stretching and smooth location, operating personnel pre-tighten anchor cable using 7 tensioning of tensioner, after the completion of tensioning,
Manually separation anchor cable head tendon, bends, around to prevent lockset from loosening.
Entire construction system can carry out continuous high-efficient repairing construction operation, after the completion of construction, it is necessary to entirely constructing
Place clear up perfect, and each equipment is transported and IMM algorithm.
The construction system and its construction method that baseboard of coal mine roadway of the invention is quickly repaired as a result, can be according to tunnel bottom
Plate repairing construction technological requirement reasonably selects its relative special-purpose equipment and simultaneously arranges the position of each equipment, by Optimal Configuration Method and
Scheduling decision method determines the quantity of each equipment and real-time matching relationship respectively.The construction system uses procedure operation, construction
Each equipment can realize automatically walk in system, and mechanization degree is high, and hand labor intensity is small, can greatly improve baseboard of coal mine roadway
Repairing construction speed improves operating environment, reduces construction cost.
