Pre - construction Preparations for Anchoring Drilling Rig
Before starting the construction of the anchoring drilling rig, sufficient preparations must be made. The standardized construction process of the anchoring drilling rig requires operators to:
1、Carefully read the equipment instruction manual.
2、Check the connection status of each component of the drilling rig.
3、Confirm the geological conditions of the construction site.
These pre - construction preparations for the anchoring drilling rig can effectively avoid 80% of construction quality problems.
Operation Specifications during Anchoring Drilling Rig Construction
Professional construction with an anchoring drilling rig requires attention to:
1、Maintain a uniform drilling speed and avoid sudden stops and starts.
2、Regularly check the status of the hydraulic system.
3、Monitor the verticality of the borehole in real - time.
These key points in the construction of the anchoring drilling rig are the basis for ensuring the support effect.
Quality Inspection after Anchoring Drilling Rig Construction
After completing the construction of the anchoring drilling rig, the following must be carried out:
1、Cable - anchor tension test.
2、Inspection of grouting fullness.
3、Re - verification of the borehole position.
A complete construction acceptance process for the anchoring drilling rig can ensure the long - term stability of the project.
The crawler - type anchor drill of Hengwang Group is quite ideal for breaking through rock formations with a certain hardness coefficient. It is manifested in the tunneling of medium - hard and hard rocks. It uses a layered combined drill bit for rotary breakthrough instead of impact breakthrough. The advantage of this is that it can standardize the borehole size, reduce the wear of the drill bit and the later maintenance costs of the drilling rig.
