Embodiment Construction
[0021] The specific embodiments of the present invention will be further described in conjunction with the accompanying drawings, and the embodiments are used to illustrate the present invention, but not to limit it in any way.
[0022] The formwork device for pouring the flange plate of the box girder passing through the tunnel includes a hanging device 2, a formwork 3, a fixing device, and a driving system. Suspension device 2 comprises crossbeam 2.1 that is installed on the walking flat car 1, the oblique column 2.2 that can move relative to crossbeam 2.1, one end is hinged with oblique column 2.2, and the other end is hinged with formwork 3 suspension bar 2.3. A diagonal tie rod 2.4 is arranged between the inclined column 2.2 and the hanging rod 2.3, and the inclined column 2.2 is provided with a positioning groove matched with the inclined stay rod 2.4. Diagonal tie rods 2.4 are respectively arranged on both sides of the suspension rod 2.3 to connect with the oblique colu...

The invention belongs to the technical field of bridge construction, in particular to a supplementary cast-in-place method for flange plates for through-tunnel box beams of a high speed passenger lineand a special model frame for the method, which solves the problem of no appropriate model frame for supplementary cast-in-place construction of flange plates in the prior art. The supplementary cast-in-place method for flange plates for through-tunnel box beams is as follows: A walking flat car pre-placed on the bridge deck and a suspension device are assembled; the suspension device is fixed and realizes installation deformation when moving; the model frame is fixed and the use functions of the model frame are realized; removal is completed after completion. A model frame device for supplementary cast-in-place of the through-tunnel box beams includes a suspension device, the model frame, a fixing device and a driving system. The invention has advantages of high construction speed, safeand reliable cast-in-place of the flange beams, convenient transfer, etc, in particular to be able to make sure of passage of large special trucks transporting box beams, which has very important realistic significance for ensuring the construction period.
Description
technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a method for repairing and pouring a flange plate of a box girder passing through a tunnel for a high-speed passenger dedicated line and a special mold base thereof. Background technique [0002] At present, the medium and small span bridges of my country's high-speed railways generally adopt 24m and 32m double-line whole-hole simply supported box girders. It is not possible to pass through the tunnel during transportation. At present, the flange plates on both sides of the box girder are generally cast or installed on site, and the top width of the prefabricated box girder is limited to be able to be transported through the tunnel. [0003] In order to ensure the quality and construction safety of the pouring of the flange plate of the box girder passing through the tunnel of the high-speed passenger dedicated line, without affecting the passage of large ...
