XY-1A Water Well Drilling Rigs Features
1. With hydraulic feeding device, elevated drilling efficiency,
reduced labor strength.
2. The rig is equipped with an upper spherical jaw holding
mechanism and hexagonal kelly which can be replaced without
shutdown, high efficiency, safe and reliable.
3. A hole bottom pressure gauge is mounted indicating the pressure
in order to control the status inside the hole.
4. Compact structure, small volume, lightweight, high
detachability, easy transportation and suitable for the operations
in plains
Site investigation and soil investigation
Site investigation or soil explorations are done for obtaining the
information about subsurface conditions at the site of proposed
construction. Soil exploration consists of determining the profile
of the natural soil deposits at the site, taking the soil samples
and determining the engineering properties of soils.
Buckle the lifter into the groove of the variable diameter joint,
move the right handle of the winch to take the pad fork, take out
the perforated pipe, install the core tube, lift the drilling tool
to the top of the borehole, move the left handle of the winch
continuously, and lower the drilling tool into the borehole at a
uniform speed. When the groove of the variable diameter joint is
close to the inlet, use the pad fork to block and remove the
lifter.
What aspects should we pay attention to in the drilling process of
water well drilling rig
Bit plays a very important role in the drilling of water well
drilling rig, but the quality of a bit directly affects the
efficiency and quality of water well drilling. Therefore, in the
selection process, we should pay attention to the selection and use
of lower bit. When we are operating the drill bit, we must pay
attention to several aspects in order to better production and
operation.
1. After the drilling structure of the drill bit of the water well
drilling rig is drilled, the central drilling tool needs to be
replaced in time. First, the hole bottom needs to be cleaned, and
then the residue at the hole bottom needs to be blown away. After
the drill bit stops rotating, the drilling tool in the water well
drilling rig can be lifted up slowly. When the lifting force is
just enough to lift the drilling tool, it is the most appropriate.
2. During the drilling process, the drill bit of the water well
drilling rig shall be summarized. It is also necessary to carefully
observe the follow-up situation of the casing, timely understand
the specific situation in the hole, and keep the hole clean when
necessary. Moreover, the drill bit in the water well drilling rig
shall not be pulled out by force during the drilling process.
3. Sometimes there will be more residual rock slag at the bottom of
the hole of the water well drilling rig, and the rotating part of
the eccentric bit will be stuck by the rock slag, which will affect
its retraction and production. At this time, it is necessary to
transport air pressure, clean the hole again, make the DTH hammer
work in a short time, and then lift the central drilling tool
again.
