How to choose drilling position/ location before starting drilling?

There are many factors to consider when choosing the location of the drilling machine. The following small series will tell you about the influencing factors. Lets come look.

 

     1. The foundation trough should be excavated according to the stable slope, and the easily collapsed stratum must be dug into a stepped shape. The bottom of the foundation groove should be dug to 0.5-1.om above the groundwater level, and the distance between the groove wall and the outer wall of the wellbore is generally 0.6-1m. Ensure the normal construction of the drilling machine.

 

     2. The casting blade should be selected in solid soil layer, otherwise it should be tamped to prevent the drilling machine from tilting during the construction process. When the strength of the concrete blade is 70% of the design strength, the wellbore can be poured on the blade foot.

 

     3. The well drilling machine should be fixed with steel brazing to prevent the well drilling machine from shifting at the wellhead during work.
