No matter which construction method is not careful in the construction process, various problems will occur, and may even threaten the life and safety of construction personnel. The same is true for pipe drilling.The characteristic of pipe drilling is large torque and jacking pressure, so the quality of the equipment must be guaranteed, and no cutting corners can be made. In addition, what else should be paid attention to during the construction process? Next, let's take a look at the precautions in the construction process of follow-up drilling.

1.  During the drilling process , due to the continuous downward deflection of the drilling tool under the action of gravity, the drilling rig is upturned. The longer the drilling, the more obvious this phenomenon. Therefore, the inclination angle of the drilling rig should be less than the designed inclination angle.

2.  When drilling with the pipe , after confirming that the drill bit is in contact with the gravel soil layer, first turn it around, and then drill with the wind impulsively after it is normal.

3.  During grouting, the proportion of cement mortar should be strictly controlled to ensure that the strength of grouting meets the requirements of the design plan. In addition, the grouting pipe must be carefully checked for cracks or blockages before use, and whether the joints are firm to prevent cracking and grouting when the grouting pressure increases.

4.  Before grouting, lead the road with water and wet the grouting pipeline; after grouting, the grouting pipeline and grouting equipment should be cleaned in time; the natural protection after grouting cannot exceed 7 days.

5.  Since follow-up drilling has high requirements for follow-up and other configuration equipment, don't try to be cheap and not pay attention to the quality of the equipment used in follow-up drilling. This is related to the efficiency of hole formation.

6. The  scaffold should be inspected in detail before being put on the shelf, and the mechanical equipment should be maintained regularly. Do not keep it in use for a long time. Remember to check the loading and unloading equipment at any time before and after the end of the daily construction. If problems are found, they must be dealt with in time without delay.

The precautions mentioned above hope that you can pay more attention to the construction.
