Drilling Rig XPB-20

1.The Main Using of the Drilling Rig
This drilling rig is mainly used for the reinforcement of all kinds of weak foundation, anchoring deep foundation pit and reinforcing the bridge piers of railway and roadbed as well as the dam seepage foundation. Through the combination of different mould plate, it can meet the different needs of fixing spray and rotary spray and to meet the demands of engineering for the single, double and triple tube.

2. The Characteristic of the Drilling Rig
2.1 This drilling rig can be reached the different engineering demands by using different mould plate and different tools. The users may choose its suitable drilling rig according to its needs.
2.2 This drilling rig can finish its work by one time during the engineering of drilling & rotary spray of the weak foundation.
2.3 This drilling rig uses the complete hydraulic feeding structure technique; By the controlling of hydraulic technique, the lifting of the drilling tools, the speed of the ascension of the rig can be regulated arbitrarily, and easy to work.. With this comlete hydraulic technical system, the equipment can be moved easily and conveniently, the working efficiency can be raised highly.
