BALLAST REMOVAL METHOD AND APPARATUS

摘要

A continuous method of removing ballast material particularly from a railway line bed comprising the steps of positioning an excavation apparatus (1) at the work site, advancing the apparatus along the bed to lift ballast from the bed, introducing the lifted ballast into the apparatus at one end thereof, conveying ballast from the excavation site through the apparatus to a selectively positionable delivery means (11) at the other end of the apparatus remote from the excavation site, from which the ballast is fed to a containment means for collection (14).
