Abstract

The invention discloses a synchronous jacking system for a prefabricated box girder template. The synchronous jacking system comprises jacking system bodies (1), a power system (2), a control system (3), a prefabricated box girder template body (4) and a sensor (5), wherein the jacking system bodies (1) are vertically and uniformly arranged at the lower end of the prefabricated box girder templatebody (4); the power system (2) is connected with the jacking system bodies (1) and used for providing power for the jacking system bodies (1); the control system (3) is connected with the power system (2) and used for controlling the power system (2) to provide power for the jacking system bodies (1); the jacking system bodies (1) comprise at least one pair of jacks (11); and the jacks (11) located in the same longitudinal row are connected in parallel through the power system (2). According to the synchronous jacking system for the prefabricated box girder template, millimeter-level intelligent pre-camber adjustment of the prefabricated box girder template is achieved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a prefabricated box girder formwork synchronous jacking system. Background technique [0002] The bridge synchronous jacking technology is to use rigid columns to support the beam body, sensors to provide feedback, computer-controlled hydraulic system synchronization and hydraulic jack clusters to achieve jacking under the premise of ensuring the integrity and use of the bridge structure (especially the statically indeterminate structure). . This technology can control the attitude of the beam body during the jacking process, realize multi-point synchronization, equal proportion and anti-slope jacking, and can also realize the long-term stay of the beam body in the air and the fine-tuning of the beam body posture. [0003] Patent CN88209168 discloses a hydraulic lift synchronous control device for construction. It consists of pump station, synchronizer, hydraulic press, hydra...
