Q:How to choose a proper drilling rig ?
A:According to your site actual situation,including the rock structure,hole depth, hole diameter,drilling technical methods etc.
Q:What is the deepest hole can a water well drilling rig drill ?
A: Our model FY800 crawler water well drilling rig, the deepest hole can drill is 800m depth when diameter is 219mm or 203mm.
Q:What is the advantages of jet grouting ?
A: Jet grouting is used as a targeted and selective treatment for certain soil layers and can therefore, for example,
"fill" karst anomalies or provide deep treatment of soft layers of soil lying under thick,compact strata.In some special cases, it is also used to motigate liquuefaction risk within a soil. Finally, the drillling machines uses are small enough to work within buildings, to underpin existing structures and to operate in areas that are difficult to access.
Q:What column diameters can be obtained by jet-grouting ?
A:Depending on the equipment used, the energy applied and the type of ground,columns can be implemented with diameters between 0.5 and 3.0 metres.The largest diameters are obtained by simultaneously or sequentially injecting several types of fluid(double jet=slurry+air,triple jet=slurry+air+water.)
Q:What`s the jet grouting technique ?
A:One or several jets of fluid with high kinetic energy are used to break apart and mix the ground with liquid cement slurry so as to form a colum
of "soil concrete".
Q:What are jet grouting techniques applicating for ?
A:Underpinning of existing structures;diaphragm walls for dam and cofferdam cut-off walls,
river embankments structural and waterproof cut-off walls;box shape underground structures'
diaphragm walls gaps repairing. Tunnel consolidation.
Q: Anchor drilling rig is a kind of drilling rig, can it be used in infrastructure construction?
A:Anchoring rig is a kind of drilling rig, which is good used in infrastructure construction, because it has good use effect and easy to use.In the foundation engineering construction, it can be used for bolt construction, dry mortar construction and drilling of various engineering survey holes and micro-pile holes, as well as drilling with auger hammer and scraper.Moreover, it can be regarded as a new and efficient drilling equipment.

With English instruction manual of the machine and how-to drilling video,it`s easy for everyone to inprove their drilling techniques and practics.
Q:What is the drill bit selection for a core drilling rig ?
A:The choice of drill bit for core drilling machine mainly depends on the purpose and operating environment of the equipment. If it is used for drilling wells with a lot of rocks, diamond drill bit or compound drill bit can be used.If drilling soil layer, can use alloy bit, and as for the bit price, mainly depends on the size of the bit diameter, the two are proportional to the relationship, that is, the larger the bit diameter, the higher the product price.
