Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] In this embodiment, the method for adjusting the track base plate 1 in the turnout area includes the following steps:
[0033] Step 1, set up some crossbeams 7 across all base plates 1 above the track in the turnout area, some crossbeams 7 in this embodiment are along the longitudinal direction of the track (the longitudinal direction referred to in this embodiment refers to the direction in which the track extends, and the horizontal direction refers to the direction in which the vertical track extends Direction) are arranged at intervals in turn, and a plurality of supporting piers 3 are built on the ground on both lateral sides of the track. A vertical jack 6 is installed on the upper end surface, and the shell of the vertical jack 6 is rested on the upper end surface of the supporting pier column 3. The lower ends of each b...

The invention relates to the repairing field of slab ballastless tracks, in particular to a method for repairing a slab ballastless track in a turnout zone. A plurality of cross beams crossing all base plates are erected above the turnout zone track; vertically-downward acting force is applied to the middles of the cross beams to enable the middles of the cross beams to be bent downwards to generate pre-deformation; after pre-deformation is completed, all the base plates are leveled to be in the same plane, and then the cross beams and the base plates are connected into a whole through rods; the two ends of each cross beam are ejected vertically to enable the cross beams to drive the base plates to ascend to adjust the vertical position of the base plates; then the base plates are pushed horizontally and transversely to adjust the transverse position of the base plates; after adjustment, mortar is poured below the base plates; and after the mortar is solidified, the base plates are put down to complete repairing construction. According to the method, through a center hole jack, the bending deflection of the middle portions of the cross beams is removed, and the lifting heights of all the base plates in the turnout zone are kept consistent; and the structure is simple, mounting is convenient, and a great popularization value is achieved.
Description
technical field [0001] The invention relates to the field of repairing ballastless tracks, in particular to a repairing method for slab ballastless tracks in turnout areas. Background technique [0002] The high-speed railway turnout relies on the guiding effect of the wheel rim of the rolling stock and the combined force of the turnout setting, so that the rolling stock travels from the original one track and splits into two or more tracks, so that the rolling stock turns from one track to the other. Another strand of wiring connects the device. Each group of turnouts consists of three units: a switch, a switch center, two guard rails and a switch sleeper. The two movable rails are moved by the lever principle by the long handle, so that the wheel rim of the vehicle drives into the predetermined route according to the opening direction. Therefore, it can also be said that a railway turnout is a combination of line-to-line connection, crossover, connection and crossover, a...
