Abstract (en)
[origin: WO8600834A1] A method of cleaning a pipeline which has been previously used for pumping concrete comprising attaching one end of a vessel to the pipeline, the vessel having air escape means adjacent said one end of the vessel, locating an object in the pipeline remote from said vessel and propelling the object along the pipeline towards the vessel with air to thereby push concrete before the object and permitting air to escape via said air escape means once the object has passed said means whereby to reduce the force of air tending to propel the object.
