The
bolter machine is suitable for soil nails made of various materials (such as angle steel, rebar, steel pipe, etc.). There are two methods for making soil nailing walls: one is to insert the ribs by drilling, and then grouting to form mortar anchors. This method is time-consuming and costly, and it is difficult to construct convective sand layer and sandstone layer. The second is to make the soil of the reinforced bar, angle steel, steel pipe and other materials into the soil nails by mechanical or artificial means into the soil layer or sand layer to form the soil nail wall.
Bolter machine Precautions for use
1. Before drilling the
bolter machine, it is necessary to ensure the stability of the top plate and the coal gang for safe operation.
2. Stop the anchor rod machine on the ground. Since the rig is placed on the ground, once the ventilation is mishandled, the air leg is extended and an accident is formed.
3. When drilling the
bolter machine, stop the gloved hand to hold the drill pipe.
4. When opening the eye position, the rig should be stabilized to open the eye.
5. When the pneumatic bolting machine is drilling, the average leg thrust should be added at the same speed to prevent the drilling speed, the stuck drill, the broken brazing, the cracking blade and the like formed by the uneven thrust.
6. When the bolt rig falls back, the hand should not be supported on the air leg to prevent injury.
7. When the bolt rig is loaded and unloaded, it will exhibit a counter torque. But you can hold the rocker arm and get a balance. Especially when loading and unloading, the operator should pay more attention to the position and reasonably manipulate the rocker handle.
