Have introduced the construction technology of anchor cable and some improvement schemes, now just analyze the anchor construction matters needing attention:

     The 1 hole is not successful, to adjust the hole, to waste mortar to fill holes, further opening, adjust the angle to the + 2 DEG, and the pipe joint anchor rod used are different;

     2 free section plastic anticorrosive layer damage to use adhesive tape wrapped around the first, use electrical tape wrapped around the second, its length than the damaged section ends of each of the 5 cm;

     3 to prevent welding burn and hard hitting steel wire, if the grouting pipe blocked, can pull out the grouting tube in situ plus grouting pipe;

     4 grouting pipe after feeding, to maintain smooth, if the grouting pipe blocked, can pull out the grouting tube in situ plus grouting pipe;

     5 in the construction process to protect the exposed end of the anchor has been sent, steel wire can not be mechanical rolling, deformation or breakage, the use of W strip also should notice to prevent deformation and breakage;

     6 in the mobile slope construction, special attention should be paid to anchor length and construction time, slope sliding rate adaptation.

     These are Shandong with the Swiss mining science and technology limited company set many years of production experience summed up, believe that will certainly be helpful.
