Additional Information:
  • A length of PVC pipe (20mm OD, 16mm ID) with the back end sealed, is inserted in the hole. This becomes the permanent housing for the MTL. The Laser is turned on & inserted into the PVC pipe. A check is made to make sure that the MTL can be aligned to the target.
  • The PVC pipe & laser are removed & the hole is 1/3 filled with chemical grout. The pipe & laser are reinserted so that the pipe is flush to the rock surface.
  • As the grout cures, it may move the pipe slightly, so the laser and the laser dot should be resurveyed.
  • The final bearing & dip as described by the MTL1 is calculated & recorded.
  • The pipe is locked into position by the cured grout & is ready for subsequent use.
