[0002] Drilling operations are the most important part of engineering surveys. The speed of its progress is the main factor affecting the progress of subsequent projects. Drilling operations are often carried out in wilderness areas with limited construction conditions. In many cases, it is impossible to get water nearby. On the other hand, drilling uses a large amount of water, so whether it is to extract natural groundwater or to transfer tap water from nearby settlements, it is necessary to lay water pipes across a long distance. In winter construction in the Northeast, the outdoor temperature is often below -20℃, which is far below the freezing point of natural water. Practice has proved that even if it is flowing water in a water pipe, when the water pipe is exposed to a surface temperature below -20℃ for more than 1 hour, the water in the water pipe will still gradually freeze, causing the water pipe to be blocked, greatly affecting the construction progress of field drilling.
