The short comings of the split set stabiliser 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 low anchoring force of the steel bar, and the cast-in-place slab cannot be manipulated very well; when the damage of the split set stabiliser twist drill is serious, it will not be replaced and replaced, resulting in a small straight diameter of the drill hole, time-consuming and laborious installation of the bolt, and even lead to The installation is not timely. The anchor rod cannot perform the anchoring effect of the steel bar; when drilling the anchor rod hole, you do not pay attention to often moving the drill, changing the position of the drill, and drilling several holes in one part; when drilling the top hole, immediately use a long drill rod to drill . The installation angle of such a split set stabiliser often does not conform to the requirements of the design scheme.

How to use the split set stabiliser safely:

1. Before the bolting machine 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 drilling tool with a hand wearing rubber gloves.

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

5. When the pneumatic bolter is drilling, the thrust of the air leg should be increased at an even rate to avoid accidents such as slow drilling, stuck drill, broken drill, and broken edge due to uneven thrust. Split set stabiliser.
