EPBM

OVERVIEW

Earth Pressure Balance Machine (EPBMs) Systems install pipe by pipe jacking or segment erecting methods. EPBMs excavate soil while balancing machine and soil pressures to minimize ground settlement. With both methods, soil from the EPBM cutter chamber is injected with foam and slurry to balance the face pressure then removed through screw conveyors and a haul unit system. The operator guides the EPBM and monitors targeting data, pressures, position, speed, torque and flow from a control console to pilot an accurate course and achieve maximum productivity rates. A series of back-up cars follow along behind the EPBM, each with a special function. A power container distributes power to EPBM operations and foam and slurry plants provide additives which aid in soil removal. The EPBM cutter head design and power source can be configured to best meet geological and performance requirements.
