Ballast processing method for use during railway track maintenance operation, involves hammering largest ballasts, and retrieving ballast whose dimensions are comprised between predetermined upper and lower values

摘要

#CMT# #/CMT# The method involves removing polluted ballast cuttings under a railway track along a predetermined width and separating soil from ballasts by evacuating the soil. Stops are recreated and the largest ballasts are hammered. The ballast whose dimensions are comprised between predetermined upper and lower values is retrieved. The retrieved ballast is washed by a mechanical action of washing with water. A railway track is reloaded by utilizing the washed ballast and a new ballast. #CMT# : #/CMT# An independent claim is also included for a device for processing a ballast during maintenance and servicing operations of a railway track. #CMT#USE : #/CMT# Used for processing a ballast during maintenance and servicing operations of a railway track (claimed) by a ballast clearing machine that is towed by a motor unit and utilized for evacuating the ballast toward a storage wagon and replacing the extracted slurry by a new ballast, during the re-ballasting operation. #CMT#ADVANTAGE : #/CMT# The method allows to hammer only the largest ballasts in a controllable manner without hammering the smaller ballasts having risks of break, thus allowing to wash the ballasts correctly so as to obtain the ballast without any impurities. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an installation for hammering and washing a ballast and a wagon for processing a washed slurry. 1 : Ballast clearing machine 3 : Railway track 4 : Re-ballasting and ballast clearing unit 5 : Drive unit 13 : Conveyor.
