Simultaneous drilling and grouting make it possible for reduced overhead, restricted obtain installation. Micropiles are generally desired to “H” piles attributable to overhead Bodily constraints.
Selected soil problems will obstruct installation and also thwart the progression of traditional underpinning answers.
Before hardening of the รับตอกเข็มไมโครไพล์ principal grout, very similar grout is injected once by using a sleeve grout pipe at a stress of the nadir of one.0MPa.
