1. The drilling rig hydraulic transmission of the rig effectively utilizes the power. This makes the overall power loss small and the drilling cost low.
What is the construction technology of de watering well?
Well point measurement and positioning → hole digging and casing embedding → drilling rig in place → drilling → hoisting well pipe → back-filling filter material (coarse sand or gravel) between well pipe and hole wall → hole washing → drainage pump in well pipe and installation of pumping control circuit → trial pumping → normal operation of well point → de watering completion, pipe pulling → well sealing.
Precautions for drilling machine working at low temperature
1. In the low temperature environment, the land will become hard, so when we choose the site, we need to have some requirements. The site needs to be flat and the road needs to be unblocked. This must be ensured.
2. The drilling machine mainly uses triangular support, especially in the case of low temperature, we should ensure that the support of the drilling machine is firm and reliable. Our staff need to regularly check and deal with hidden dangers in time once they are found. We must not be careless
3. Although we work at low temperature, we can not ignore the problem of fire prevention. The configuration of fire-fighting equipment must be reasonable and meet the fire-fighting requirements.
4. Low temperature, low temperature, what is the most important? Of course, our friends should pay attention to their warmth when working. Only when they are warm can we better put ourselves into work.
5. The temperature is low, which will definitely have certain impact on the construction. We must pay attention to warmth and safety
