Micropiles (mini piles, pin piles, needle piles, and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bars. .
Micropiles (mini piles, pin piles, needle piles, and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bars. .
The micropile casing generally has a diameter in the range of 3 to 10 inches. Typically, the casing is advanced to the design depth using a drilling technique. Reinforcing steel,. .
Comprehensive fleet of rigs and tooling for difficult subsurface conditions and limited access Alleviates quality assurance concerns associated with cast-in-place piling in weak soils Can be combined with other techniques to meet unique or complex project requirements cost-effectively and efficiently .
The finished micropile (mini pile) resists compressive, uplift/tension, and lateral loads and is typically load tested following ASTM D 1143 (compressive), ASTM D 3689 (uplift/tension), and ASTM D 3966 (lateral). Capacities vary depending on the micropile size and subsurface profile. Allowable compressive capacities of more than 500 tons have. These drills are primarily used to drill tie-backs using a high-powered percussion head. They can also be equipped to drill using cased methods as required. The units can be mounted on a variety of excavator carriers to suit individual project requirements.
