Problems solved by technology

[0002] At present, although the walking-type jacking device can meet the construction needs, the jacking speed of the box girder to be installed is too slow, and the jacking speed is 0~2m / h. A lot of time was wasted in the process of returning to the position, resulting in low efficiency of the whole set of equipment; and the working status of each jacking device was manually monitored on site, and the manual feedback when the status feedback information of each point of the jacking device met the corresponding working conditions was delayed. A lot of working hours directly affect the working efficiency of the pushing equipment

Abstract

The invention discloses a walk-type continuous pushing system and a construction method. The walk-type continuous pushing system comprises at least two sets of pushing equipment arranged along the same direction. The two sets of the pushing equipment are arranged between temporary piles used for temporarily supporting a to-be-mounted box girder. Each set of the pushing equipment comprises a supporting platform which is supported by vertical jacking oil cylinders arranged on the lower end face of the supporting platform. The upper end faces of the supporting platforms are connected with load bearing beams in a sliding mode. Horizontal pushing devices are arranged on the supporting platforms and the output ends of the horizontal pushing devices are connected with the load bearing beams. Through continuous working of the pushing equipment, lost work time of original vertical jacking oil cylinder return strokes and horizontal pushing oil cylinder return strokes is utilized to increase pushing speed and efficiency, so that walk-type continuous pushing of to-be-mounted bridges can be realized.

Description

technical field [0001] The invention relates to the technical field of bridge use, in particular to a walking-type continuous jacking system and a construction method. Background technique [0002] At present, although the walking-type jacking device can meet the construction needs, the jacking speed of the box girder to be installed is too slow, and the jacking speed is 0~2m / h. A lot of time was wasted in the process of returning to the position, resulting in low efficiency of the whole set of equipment; and the working status of each jacking device was manually monitored on site, and the manual feedback when the status feedback information of each point of the jacking device met the corresponding working conditions was delayed. A lot of working time directly affects the working efficiency of the pushing equipment. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned background technology, and provide...
