600 nos. of 600mm dia bored cast in-situ piles taken to 25m depth and completed in 60 days.
Project Overview
One of our largest bored cast in-situ packages, executed for Coromandel Engineering Constructions at their Pondicherry development. The scope covered 600 piles of 600mm diameter socketed to a founding depth of 25 metres.
Boring was carried out by the Direct Mud Circulation (DMC) method as per IS 2911 Part 1 Sec 2, with bentonite circulated under pressure to keep the bore stable and to flush the bored muck to the surface. Hard strata was penetrated using appropriately weighted chisels until the specified socketing was achieved.
Reinforcement cages were lowered after the specific gravity of the outflow confirmed a clean bore, followed by tremie concreting in a continuous pour.
Scope Highlights
- Tractor mounted rotary DMC rigs deployed in multiples to hold the 60-day programme
- Bore cleanliness verified by specific gravity checks before every concrete pour
- Continuous tremie concreting with cube testing on site
