2. Brief Introduction

Tremie pipes are normally used to pour concrete into a drilled pile, after the steel cage reinforcement is placed in operation, to avoid concrete pile breakage or gaps. During the operations they are lowered inside and through the steel cage reinforcement to protect concrete from soil contamination water filtering and to avoid any possible concrete quality corruption. Tremie pipes are made of quality drawn steel plates in order to guarantee high resistance elements.

Pipes sections can be connected by two kinds of coupling systems: threaded joints and wire cable joints. While threaded tremie pipe are equipped with male/female joints with thread, the wire cable system is designed for quick assembly /dismounting of the various pipe sections during the concreting operations. Using wire cables joints water and mud penetration is prevented by O-ring seals applied in between male and female joints.
