Description

technical field

[0001] The invention relates to a railway maintenance machine, in particular to a drainage ditch digging device for a railway bridge. Background technique

[0002] The cleaning of existing railway track bed pillow bottoms is carried out by a cleaning machine. Due to the certain slope of the existing bridge pillow bottom, the bridge drainage ditch area cannot be cleaned thoroughly after cleaning by the screen cleaning machine. This means that the excavation guide groove cannot be cleaned by the screen cleaning machine The thickness of the ballast will affect the drainage performance. Contents of the invention

[0003] The present invention aims to solve the problem that the existing bridge cleaning machine cannot dredge the bridge drainage ditch when cleaning the bottom of the bridge pillow, and provides a drainage ditch excavation device for railway bridges, which can backfill the ballast after the screen is cleaned and the guide groove is excavated.
