Abstract
A machine for repairing a ballast bed has an undercutter that defines a direction of movement of the repairing machine, and a distributor for dividing a flow of ballast entering from the undercutter into a rear flow of exiting ballast and a separate front flow of exiting ballast. At least one rear screening machine is positioned behind the undercutter in the direction of movement and is fed by the rear flow of exiting ballast. At least one front screening machine is positioned in front of the undercutter and fed by the front flow of exiting ballast, and the distributor has a variator for varying the ratio between the separate first and the second flows of exiting ballast.
Claims20
A machine for rehabilitating a ballast bed comprising:
- at least one undercutter defining an operating movement direction of the machine;
- a distributor for dividing an incoming ballast stream originating from said undercutter into at least two separate outgoing ballast streams;
- at least one rear screening machine positioned behind said undercutter in a direction of movement and fed by a first of the two separate outgoing ballast streams;
- at least one front screening machine fed by a second of the two separate outgoing ballast streams, said front screening machine is positioned in front of said undercutter;
- and
- said distributor having a variator for varying a ratio between the first and second of the two separate outgoing ballast streams.
A process for rehabilitating a ballast bed comprising:
- undercutting the ballast bed by means of at least one undercutter that moves relative to the ballast bed in an operating direction of movement;
- dividing a ballast stream originating from the undercutter into at least two separate outgoing ballast streams;
- carrying out a screening of a first of the two separate outgoing ballast streams after the undercutting in the operating direction of movement;
- and
- carrying out a screening of a second of the two separate outgoing ballast streams before the screening of the first of the two separate outgoing ballast streams, the screening of the second of the two separate outgoing ballast streams is carried out before the undercutting in the operating direction of movement, the dividing making it possible to vary a ratio between the first and the second of the separate outgoing ballast streams.
