Connected sets: the bolt connecting role to be lengthened.
Plate: rock can withstand greater stress
Nut: rock stress can concentrate on the plate.
Construction technics
1.one end of the alloy drill and bolt connections, automatic anchor on the other end of the cable solder sleeve, solder tail then with trolley or handheld rig connected. Automatic anchor according to the design depth of the drilling began, filling the cooling water drilling is required. (For a longer bolt, automatic anchor sleeve connections available to connect, and then drilling)
2. remove the rig, set into the grouting stopper rod, and insert it into the hole, ready to grouting. Special circumstances into rock grouting pressure is too large or too broken, can sealing anchoring agent.
3.the quick connect end and bolt grouting joints, grouting grouting joints connect the other end.
4.starting grouting grouting, grouting to be full and shut down when the pressure reaches the design value. Grouting pressure grouting machine according to the design parameters and performance determined Fui Sha than the reference value of 1:0 to 1:1, water-cement ratio reference value of 0.45 to 0.5:1.
5.the mounting pad and nuts, and tighten the nut
