A large-toughness steel casing is often drilled down to the look depth in the course of the installation procedure. A reinforcing bar is positioned into your casing, and large-energy cement grout is poured into it.
Right after executing the Preliminary tremie grouting, stress grouting is finished concomitantly Using the lifting in the casing from your bond zone through a pre-mounted tube.
Micro-pile components circumscribe and internally reinforce the soil to create a reinforced soil composite that withstands the used load.
The determine represents a normal section of a micropile resting on a tough soil/ rock strata. The metal casing is limited on the compressive strata and extends a little bit to the challenging strata for some anchorage.
Regular ways of deep Basis installation for instance piling, or using helical piles is usually time consuming and รับตอกเสาเข็มไมโครไพล์ ราคา cost prohibitive to setup.
The size of your casing is typically from twelve to two hundred toes extensive. The size of the metal casing will count on quite a few things which includes soil Houses and depth requirements for penetration.
