What are the working steps of the trenchless drilling rig?

In the past two decades, trenchless technology has developed by leaps and bounds both in physics and construction technology. It has become a more important construction method for laying pipelines in cities. Using trenchless technology to lay pipelines has several unique advantages. How are the construction steps of the trenchless drilling rig operated? Xiaobian will say it for you.

1) The construction site has been surveyed and the construction site has been determined before using the trenchless drilling rig.

2) When the trenchless drilling rig starts to work, install and connect the guide bit and the probe battery for a long enough time, and check whether the probe emission parameters are consistent with the given technical parameters.

3) The trenchless drilling rig adopts the method of low speed and slow propulsion to improve the accuracy of drilling angle. If the angle needs to be adjusted in the drilling process, it is necessary to adjust the face angle of the bit tool to match the given angle, so that the actual pipe angle drilled out will not be too different from the given technical parameter angle.

4) When drilling in a straight line, the trenchless drilling rig shall rotate at a constant speed and keep stable, and the pipeline shall be straight.

5) After the construction of the guide hole is completed, it is necessary to pull back and ream the hole. In the process of pulling back and reaming, the diameter of the hole diameter design should be moderate. The grading reaming should be carried out according to the actual data, and the hole wall should be reinforced. During pulling back, the pull back force should not exceed the pull of the pipe.
