The shortcomings of the split set supplier lt in the application: many people in order to speed up the installation rate of the bolt, smash the bolt with a hammer to make it smaller in straight length and narrow in the width of the seam, and also decisively saw the bolt down a section, but That will result in a low anchorage force of the steel bar, and the cast-in-place slab cannot be manipulated very well. When the damage of the split set supplier twist drill is serious, do not pay attention to replacing it, resulting in a small straight diameter of the drill hole, time-consuming and laborious installation of the bolt, and even untimely installation. The bolt cannot perform the anchoring effect of the steel bar. When drilling the bolt hole, do not pay attention to often moving 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 supplier often does not match Design scheme regulations.

Safe use of split set:

1.     Before drilling the bolter, 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.

5.     When the pneumatic bolter is drilling, the thrust of the air legs should be increased at a uniform speed to avoid accidents such as slow drilling, stuck drill, broken drill, and broken edge due to uneven thrust.
