Drilled - Cast In-situ Concrete Piles
Drilled - Cast In-situ Concrete Piles These are RC concrete piles normally drilled within a common diameter of 450-1500mm. The weak, collapsible soil section is normally cased (temporarily or permanently) while the rock is not; as it is self–supporting. The pile bottom (end bearing surface) is usually cleaned up properly prior to casting, the steel cage is lowered in a centralized manner and placed in position (with the designed concrete cover allowance) and the concrete is either gravity-casted using a shoot or hopper connected to a gravity tremie pipe or pressure-tremied using a concrete pump and hose. The concrete is first placed at the bottom and allowed to displace any contaminating soil cuttings, collapse debris, groundwater and drilling fluid upwards until fresh, uncontaminated concrete emerges at the surface.
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. Hydrogeological Modeling & Monitoring AAGC has a certified engineering team specializing in civil, geological, and hydrogeological services. We deliver comprehensive site assessments and groundwater system analysis using advanced 2D and 3D conceptual modeling. Our goal is to design costeffective, environmentally friendly solutions using the latest engineering tools and technologies.
Dewatering and groundwater control system design – Flow and contaminant transport modeling – Hydrogeological behavior and water head fluctuation analysis Groundwater Monitoring & Reporting
AAGC employs skilled technicians and advanced instrumentation to monitor key groundwater parameters, including water levels, hydraulic conductivity, temperature, and pore pressure. We utilize:- Flow meters Pressure transducers with data loggers – Piezometers (standpipe and pore pressure types) – Real-time monitoring systems with 24-hour data access This ensures accurate, reliable reporting and compliance with project and environmental requirements.
