1. Application
YSSL-300 water well drilling rig, which is a full hydraulic crawler
water well drilling rig, is mainly used in water well or water
exploration hole; but also used in foundation engineering small
diameter hole grouting construction.
2. Feature
1. Drilling Rig has double power heads, needn’t driving rod; It has
the long feeding stroke which is helpful to reduce the rod
reversion frequency, avoid core block, and improve productivity. It
also can achieve compression or decompression during the full
feeding stroke.
2. Drilling Rig installed the front and the rear power heads, which
makes a variety of drilling methods possible
2.1 When drilling a hole in fractured zone or congeries, drill rod
power head connected with DTH hammer and bits, to realize
percussion rotary drilling. Meanwhile, casing tube power head
rotates the follow-up casing for protecting the hole wall. The two
power head can be synchronize to drill hole rapidly.
2.2 When drilling a hole in incoherent overlying formation,
quicksand layer and silt layer, the inner drilling tool use
conventional rotary tools or long auger drilling tools, meanwhile,
the front power head rotates the following-up casing for protecting
hole wall.
2.3 When drilling a hole in intact formation, could use power head
alone for ordinary rotary drilling or percussion-rotary drilling.
3. Floating mechanism in the main spindle of top drive power head
protects drill rod screw thread. Casing tube can also used as screw
machine to make clamping and loosening drilling tools’
mechanization.
4. Drilling Rig’s feeding structure could work with winch together
to meet special demand of technical and reduce the strength of
labor.
5. The hydraulic motor, pump and operating valve are world famous
brand products, other main assembly preferentially selected home
made reputed and high quality products. Thus, the performance of
the machine will be stable, creditable and long life
6. The drilling rig outfit strong driving force to applicable for
various drilling method such as follow-up casing drilling, anger
drilling, percussion rotary drilling, double wall TC drilling,
7. The rig is full-featured has strong ability to deal with
accident.
