Abstract

The invention discloses a prefabricated bridge abutment multifunctional lifting system and a construction procedure thereof. The prefabricated bridge abutment multifunctional lifting system comprises a lifting mechanism for lifting a prefabricated abutment and a position regulating mechanism for regulating the position of the prefabricated abutment in a three-dimensional way, wherein the lifting mechanism is connected with a bearing truss through a flexible lifting rope; the position regulating mechanism is arranged between the bearing truss and the lifting mechanism; the bearing truss is fixed on a steel pipe pile; and the steel pipe pile penetrates into an inner hole of a prefabricated cushion cap. The lifting mechanism and the position regulating mechanism are combined into one, so that lifting and position-regulating continuous construction can be realized, and the turnover utilization ratio of equipment is improved; the bearing truss can bear the position regulating mechanism and a steel pipe pile clasping mechanism in a lifting process and can be used as a connecting truss of the steel pipe pile clasping mechanism in a position-regulating construction; and the steel pipe pile is used as a stable whole, so that the stability of the position-regulating construction is improved.

Description

technical field [0001] The invention relates to the field of bridge construction equipment, in particular to a bridge prefabricated pier multifunctional hoisting system and construction steps. Background technique [0002] In modern bridge construction, in order to improve efficiency, save construction period, facilitate construction and reduce environmental pollution at the construction site, prefabrication of bridge structures has been widely used. The prefabricated structure of the bridge is transported to the predetermined location after the prefabrication is completed in the prefabrication factory, and then the prefabricated structure is hoisted in place by a large crane ship through a special spreader. [0003] At present, the hoisting and positioning of prefabricated piers requires two processes: hoisting and position adjustment. The conventional prefabricated pier hoisting system only includes the hoisting structure, and the position adjustment mechanism needs to be...
