【Summary Description】 Drill pipe is very common in some geological projects, but if it is not installed correctly, it may cause some accidents and damage.

In some geological engineeringdrill pipeIt is very common to use, but if it is not installed correctly, it may cause some accidents and damage. In fact, the installation of the drill pipe is very simple, as long as you pay attention to some details during the installation process, you can ensure the correct installation.

1When installing and using the drill pipe, the action must be slow, and the drill pipe must not hit the power head and mast, etc., so as to prevent the drill pipe body from being deformed due to bumps and bumps, causing the rod to be stuck.

2In addition, when installing and using the drill pipe, remember not to push the drill pipe with square head.

34. When the casing is placed, it is not allowed to push the steel casing with the drill pipe.

43. It is not allowed to install and use the drill pipe on the drilling rig for long-distance transportation and moving of the construction site.

5Pay attention to clamp with visedrill pipeDo not clamp the female buckle part of the female connector to prevent the female buckle from being clamped and deformed.

6Before installing the drill pipe, clean the male and female buckles, and apply screw oil (screw oil cannot be replaced by other waste oil or inferior pressure oil) to prevent premature wear or damage of the male and female buckles.

7, pay attention not to force on the buckle. When fastening, the male buckle can not impact the shoulder and thread of the female buckle, and ensure that the male and female joints are aligned. Ensure the coaxiality of the shackle of the drilling rig and the main shaft of the power head.

8Pay attention to check the wear of each part of the drill pipe, and find out the reason in time if there is abnormal wear:

1) Determine whether the drill pipe is scratched by the sharp hard substance in the hole.

23) Determine whether the drill guide device is rightdrill pipeThe scratch.

3) When the drill pipe body is scratched with a depth of about1mmUse caution when the spiral shape is more than one turn. Prevent the drill pipe from being broken during construction, causing greater losses.

94. If the drill collar is found to be damaged (cross-buckling, disorderly buckling, serious wear, etc.), it should be replaced in time to avoid damaging the drill pipe thread.

102. Pay attention to avoid mixing drill pipes of different buckle types, even if they are not produced by the same manufacturer, do not mix them (because the technical parameters, processing methods, props and mechanical equipment used by different manufacturers of drill pipes are different, the tolerance and tightness of the processed drill pipes must be different); Do not mix drill pipes with too much difference between the old and the new and the wear degree to avoid construction risks.

11Avoid connecting large diameter drill pipes with small diameter during constructiondrill pipe,(That is, the size of the drill pipe mixed use)Prevent small drill pipe from being broken or deformed due to insufficient strength.
