Segmental box girder prefabrication construction structure

Abstract

The invention provides a segmental box girder prefabrication construction structure. The structure comprises a hydraulic oil tank, movable brake wheels, a hydraulic pump, an oil outlet pipe, rubber plug shells, a hookable supporting clamping plate structure, an adjustable shunt box structure, a rotatable sealing pipe structure, a backflow conveying pipe structure, an observation piece, a lifting rod, a filling pipe, a rubber cover, a U-shaped clamping seat, a supporting pipe and an inverted T-shaped supporting seat, wherein the movable brake wheels are in bolt connection to four corners of thelower end of the hydraulic oil tank. A shunt box, connecting pipes, an oil inlet pipe, oil filling pipes and the rubber plug shells are arranged, the corresponding number of the rubber plug shells can be selected to be inserted into pipes according to the set number of the pipes in the construction process, and different rubber plug shells are filled with hydraulic oil by mutual cooperation of the shunt box, the connecting pipes and the oil filling pipes, so that a plurality of the rubber plug shells can be conveniently filled in work.

Description

technical field [0001] The invention belongs to the technical field of box girder engineering, in particular to a segmental box girder prefabricated construction structure. Background technique [0002] The segmental box girder with short-line matching method needs to install more embedded pipes during the prefabrication process, and the accuracy of the embedded pipes determines the structure and appearance quality level of the entire segmental box girder. An important part of the box girder, its accurate positioning depends on the accuracy of the position of the bellows. Accurate positioning of temporary prestressing holes and temporary hoisting holes will be the key to balance force when segmental box girder is erected. At the same time, all pre-embedded pipes run through the entire girder body, which is also the most direct and difficult to control link that affects the appearance of the segmental box girder. Therefore, during the prefabrication process, the positioning ...
