DRILLING AND MICRO PILING WORKS

Micropiles, also known as mini piles, are small-diameter (typically 6 to 12 inches), high-strength foundation elements made of steel casing or threaded bars encased in grout. They are suitable for stabilizing structures in areas with limited access or low headroom and are commonly used for upgrades with minimal disruption to ongoing operations.

Their installation involves drilling, a process where a rotating drill bit cuts circular holes into solid materials. The drill bit, often multi-point, spins at high speeds and is pressed against the surface to create precise holes for micropile placement.

TYPES OF MICRO PILING WORKS

TYPE A MICRO PILES

Type A micropiles use tremie grouting and through gravity head. The grouting is started from the bottom and follows a similar tremie grouting procedure followed in conventional piles.

TYPE C MICRO PILES

In these types of piles, pressure grouting is followed by tremie grouting. On completion of pressure grouting, a global injection grouting is performed through a pre-installed sleeve port pipe. This grouting shall be done before the hardening of primary tremie grout.

TYPE B MICRO PILES

After performing the initial tremie grouting, a pressure grouting is followed simultaneously with the lifting of the casing from the bond zone. The second stage pressure grouting is done through a preinstalled tube. Second stage grouting serves in enhancing grout soil bonding.

TYPE D MICRO PILES

This method is similar to Type C . In this method primary grout is done under pressure and after hardening secondary grout is done through installed sleeve ports. Packers are also provided for multiple injections.
