A micro pile is a pile with a small diameter (Approx.100-400mm) and therefore cannot be installed to as great a depth as larger diameter piles.
It is drilled and grouted to support structures in all ground conditions.
It is widely used in the construction field because of the low vibration and no noise, like housing area, school, hospital or any location, where noise is prohibited while piling.

Ground Condition
Geotechnically, micro pile is most suitable in the following ground conditions:
(1) Shallow Bedrock
(2) Boulders and Cavities
(3) Intermediate Hard Strata
(4) Underpinning

How to Install Micro Pile?
(1) Drilling and Flushing (a high pressure compressor will be used for flushing out the drilled materials)
(2) Withdrawing and Drilling String
(3) Inserting Steel Reinforcement and Grouting
(4) Completed Micro Pile

Low Pipe Jet Grouting Drilling Rig
This low pipe jet grouting drilling rig is a kind of drilling tool. It is used for conveying slurry, compressed air and water, etc. It can install micro pile to fix the construction. Under the working condition of high pressure, the grout drilling machine can guarantee continuous dynamic property and static property.
It is widely applied to railway, highway, building, water conservancy, electric power, etc. It is mainly used for reinforcing foundation, seepage-proofing, water-proofing, maintaining existed load bearing.
The grouting pipe drill equipment covers XP-20 (Standard Model) jet grouting drilling rig, XP-20A (Enhanced Type) jet grouting drilling rig and XP-20B jet grouting drilling rig.
