Crawler Drilling Rig For Water Well Drilling Rig Machine Driven By
Diesel Engine
Introduction of 200 crawler type water well drilling rig:
The Pneumatic Water Well Drilling Rig can create drilling jobs in
different strata, borehole diameter can up to 140-325mm. The
crawler water drilling rig with hydraulic technology,supporting
high torque hydraulic motor rotation and large bore hydraulic
cylinder push, the multi cylinder engine of famous factory provides
power for the hydraulic system, two stage air filter, air
compressor air intake design, prolong the service life of diesel
engine. Special pump set design is convenient for maintenance and
reduce the cost of maintenance. Centralized control of the

Why is the water well drilling rig not suitable for use in rainy
days?
After the well is completed, it is necessary to pump water to check
the results. Under normal circumstances, a large draw down pumping
can be done. The stable duration of the water level shall not be
less than eight hours, and the water flow of the dynamic water
level of the well shall be measured at the same time. The well
drilling project shall ensure the smooth drainage of the
construction site, so the rainy season shall be avoided. When
working while excavating, the excavation slope shall be determined
according to the physical and mechanical properties of the soil
layer, generally 1:1.5, and there shall be a certain distance from
the toe of the spoil slope to the upper opening of the excavation.
For large wells with water inflow from the shaft wall, the water
inlet hole and inverted filter layer of the shaft wall must be
arranged according to the design requirements, and the water inlet
hole shall be prevented from being blocked during construction. The
filter material enclosure at the aquifer shall meet the
requirements, the backfill shall have a certain super elevation,
and the frozen soil in the backfill in winter shall not exceed 15%.
