Abstract
In a method for stabilizing an earth formation exposed after removal of a track and ballast, in a first working pass in a work section following a rear crawler track with regard to a working direction, parallel to the removal of the ballast the earth formation is loosened up, aggregates are introduced, and grading takes place. In a second working pass, the earth formation to which aggregates have been added is mixed thoroughly by getting picked up by means of a clearing chain and transported onward to a discharge point located behind the rear crawler track and discharged again upon the exposed earth formation, after which, by grading and consolidating the discharged earth formation, a rehabilitation layer is formed.
Claims5
A method for stabilizing an earth formation of a track, wherein the earth formation, exposed after removal of the track and ballast, is mixed with aggregates and leveled and consolidated, thus forming a protection layer, comprising the following features:
- a) in a first working pass—in a work section adjoining a rear crawler track with regard to a working direction—parallel to the removal of the ballast the earth formation is loosened up, aggregates are introduced, and grading takes place,
- b) in a second working pass, the earth formation to which aggregates have been added is mixed thoroughly by getting picked up by means of a clearing chain and being transported onward to a discharge point located behind the rear crawler track and being discharged again upon the exposed earth formation, after which, by grading and consolidating the discharged earth formation, a rehabilitation layer is formed.
