Abstract

The invention discloses a translational traction construction method of PC narrow and high track beams on cast-in-place beams, which is characterized in that it comprises the following steps: S1, translational track installation: laying leveling pads on the cast-in-place beams, and then leveling pads Lay two translational tracks through the cast-in-place beam; S2, construction of the translational traction mechanism; S3, hoisting and fixing of the track beam: hoist the track beam from the side span side of the cast-in-place beam to the two vertical support beams on the horizontal support beam between, and plug the buffer reinforcement pad between the vertical support beam and the track beam; S4, track beam translational traction. The translational traction construction method of the PC narrow and high track beam on the cast-in-place girder of the present invention solves the problem that when the PC narrow and high track beam is erected on the cast-in-place pier column in the middle of the bridge and the cast-in-place beam, the crane and the beam transporter cannot be moved due to the load bearing of the bridge. The technical problem of driving to the bridge for hoisting of track beams.

Description

technical field

[0001] The invention belongs to the technical field of straddle-type monorail traffic construction, and in particular relates to a translational traction construction method of a PC narrow-high track beam on a cast-in-place beam. Background technique

[0002] The straddle-type monorail traffic is supported, stabilized and guided by a single track, and the car body uses rubber tires to ride on the track beams. The characteristics of the straddle-type monorail are strong adaptability, low noise, and small turning radius , Strong climbing ability. The monorail system can better adapt to the complex terrain and landform environment. The average width of the viaduct piers of the straddle-type monorail is less than 2m. Compared with other elevated rail transits, the bridge piers occupy nearly half the width of the bridge. The columns can be erected in the center of urban roads or in the green belts on both sides of the road, which occupies a small area and has les...
