Micro or Mini piles
Micro and mini piles are small-diameter (100–250mm) deep foundation elements, installed to depths of 3m to 15m. They are reinforced with steel bars or sections and grouted or microconcreted using tremie methods to ensure full encapsulation and displacement of debris. Various techniques are employed, including the use of the drilling rod or tremie pipe as reinforcement, or postplacement of rebar into the filled hole.
Drilling may involve permanent or temporary casing, including advanced systems like Symmetric/Robit casing or hollow stem augers. These slender elements require careful design consideration for buckling, lateral loads, and group effects due to their geometry and application in
constrained or sensitive environments.
Deep well systems are effective dewatering solutions using submersible pumps installed in wells ranging from 75mm to 600mm in diameter, capable of handling flows from a few to thousands of GPM. Unlike suction-based systems, deep wells are ideal for greater depths, typically from 6m to over 100m. They are most effective in deep, homogeneous aquifers and provide highvolume pumping with stable groundwater control. Fujian delivers turnkey deep well solutions from design and drilling to pump installation tailored to project-specific needs.
