Translation traction construction method for PC narrow and high track beam on cast-in-place beam

Abstract

The invention discloses a translation traction construction method for a PC narrow and high track beam on a cast-in-place beam, which is characterized by comprising the following steps: S1, translation track installation: paving a leveling cushion block on the cast-in-place beam, and then paving two translation tracks penetrating through the cast-in-place beam on the leveling cushion block; S2, constructing a translation traction mechanism; S3, hoisting and fixing the track beam, specifically, the track beam is hoisted to the position between the two vertical supporting beams on the transverse supporting beam from the side span side face of the cast-in-place beam, and arranging buffering and reinforcing cushion blocks additionally between the vertical supporting beams and the track beam; and S4, performing track beam translation traction. According to the translation traction construction method for the PC narrow and high track beam on the cast-in-place beam, the technical problem that when the PC narrow and high track beam is erected on a cast-in-place pier column in the middle of a bridge and the cast-in-place beam, a crane and a beam transporting vehicle cannot be driven to the bridge to hoist the track beam in consideration of bridge bearing is solved.

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...
