1Anchor2Jet-grouting.3Dewatering for foundation pit4.With the crawler
1.Apply to various construction technique:1.1Anchor.It can be used in anchor drilling when the main shaft connect with drill rod/drill pipe, casing, also with casing-followed drill tools.
1.2Jet-grouting.It can be used in single-pipe,double –pipe and triple-pipe jet-grouting,etc.It can meet the following construction technique after equipped different module:
1.3Dewatering for foundation pit
1.4Micro-pile
1.5Geothermy hole(water well) engineering and expolration
1.6CPT(5T of the CPT)
1.7Dynamic Penetration
2.Based on different stratum, we can adjust torque and rotary speed of drilling rig to increase drilling rig’s adaptability.At the same time,we can adjust torque and rotary speed according client’s request.
3.With the crawler,it has fast mobility ,accurate location, time-saving, good reliability and stability and other technical feature.
4.It can reduce labor intensity and increase efficiency after equip the clamping and stability and other technical feature.
5.We also Research and Design the match drilling tools to meet the following construction technology:
5.1Anchor; 5.4DTH hammer Impact Drill by Air;5.2Jet-grouting 5.5DTH hammer Impact Drill by Water;5.3Mud Positive Circulating Drill 5.6Muti-liquid Reverse Circulating Drill.
