Description

Technical Field

[0001] The utility model belongs to the field of continuous beam construction, in particular to a deviation-correcting device for a jacking continuous beam. Background Art

[0002] Prestressed continuous beam is a kind of bridge. The construction of prestressed continuous beam often adopts the top-pushing method. The top-pushing method means that when the structure needs to pass under the embankment of the existing line, in order not to disturb the existing line, the structure can be built in sections on one side of the embankment, and then pushed by jacks to make it pass through the embankment. Specifically, the segmented precast concrete beam segments are connected into a whole with longitudinal prestressed tendons, and the beams are pushed out section by section, and then the next beam segment is cast on the narrow beam pedestal. This repeated cycle of construction is the top-pushing construction method.

[0003] Since the span of the continuous beam is large and it is constructed by moving in segments, when a segmental beam has a slight angular deviation, the lateral deviation of the continuous beam will become larger and larger during the movement, which will lead to unstable installation of the continuous beam. Therefore, after the construction of the continuous beam, a correction device is often used to correct the lateral deviation of the continuous beam.

[0004] Most of the existing correcting devices are used in combination with multiple jacks and Teflon plates. The vertical jack lifts the continuous beam, and the horizontal jack pushes a vertical jack to move. Under the action of friction, the vertical jack drives the continuous beam to move horizontally. However, the multiple jacks are installed separately on the piers, and there are no other fixing devices, which leads to the instability of the installation of the entire correcting device.

[0005] In order to avoid the above technical problems, it is necessary to provide a jacking continuous beam correction device to overcome the above defects in the prior art. Utility Model Content
