Insufficiency of split set stabilizer in Application. In order to speed up the installation rate of the anchor rod, many people hit the anchor rod with a hammer to make it smaller in straight length and narrow in the seam width, and also decisively saw the anchor rod down a section, but this will cause the anchoring force of the steel bar to be low, which cannot be very Good handling of cast-in-place slabs. When the damage of the split set bolt twist drill is serious, it will not pay attention to the replacement, resulting in a small straight diameter of the drill hole, time-consuming and laborious installation of the bolt, and even untimely installation. Do not pay attention to often move the drill, change the position of the drill, and drill several holes in one part; when drilling the top hole, immediately use a long drill rod. The installation angle of such a split set bolt often does not meet the requirements of the design scheme.

Safe use of split set stabilizer:

1.     Before the bolter drills, it is necessary to ensure the solidity of the cast-in-place slab and the coal gang, and carry out safety education.

2.     Discourage the bolter from laying flat on the ground. Because the drilling rig is flat on the ground, once the ventilation operation is wrong, the air leg protrudes out, which will cause an accident.

3.     When the bolter is drilling, it is discouraged to hold the drill with rubber gloved hands.

4.     When opening the eye position, the drilling rig should be stabilized and the opening work should be carried out.
