Bridge multi-dimensional deviation rectifying device

Abstract

The invention discloses a bridge multi-dimensional deviation rectifying device which comprises a jacking system and a translation system, wherein the translation system is arranged around the periphery of the jacking system, and the translation system applies an acting force to the jacking system and enables the jacking system to slide; the translation system comprises a bottom plate, a rotating body and a pushing jack, the rotating body is rotatably connected to the periphery of the bottom plate, the pushing jack is installed on the rotating body, the piston end of the pushing jack penetratesthrough the rotating body and extends to the inner side, and the pushing direction of the pushing jack is adjusted in a 360-degree rotating mode through the rotating connection; the jacking system isconnected to the bottom plate in a sliding mode, and the jacking system slides relative to the bottom plate under the pushing effect of the pushing jack. Through mutual cooperation of the jacking system and the translation system, vertical jacking and three-dimensional deviation rectifying adjustment in the horizontal direction can be achieved, and the rotating body and the jacking system arranged on the rotating body can achieve 360-degree deviation rectifying adjustment in the circumferential direction by rotating the jacking jack.

Description

Technical field [0001] The application belongs to the technical field of bridge deviation correction, and specifically relates to a bridge multi-dimensional correction device, which can meet the requirements of simultaneously adjusting the bridge deviation in both horizontal and vertical directions. Background technique [0002] The bridge structure is a kind of overhead artificial passage for passage, which is composed of an upper structure and a lower structure. The upper structure includes the bridge body and deck; the lower structure includes the pier, abutment and foundation. The original purpose of building a bridge was mainly to solve the problem of cross-water or cross-valley traffic. However, with the increasing advancement of modern bridge building technology, the use and scale of bridges have become more and more extensive. For example, large and medium-sized cities introduce viaducts to relieve traffic pressure. Span and style are also endless. [0003] However, in re...

Problems solved by technology

[0003] However, in recent years, investigations have found the following problems: (1) Various problems have appeared in many existing bridges, such as bearing disease, structural protective layer falling off, bridge deck cracks, etc.; (2) the original bridges The design does not meet the existing planning or use functions, for example, there is a linear deviation in the connection between the original bridge and the new bridge in urban reconstruction, and the lack of clearance at the bottom of the bridge affects navigation and traffic

When the bridge is jacked up, it will largely cooperate with the slope adjustment, because the bridge will be at a certain slope angle, and the horizontal component force must be generated when the bridge is jacked up. Even if a series of limit measures have been taken in advance, the bridge cannot be completely avoided. sideways horizontal shift

[0005] In view of the deflection problem of the bridge structure after jacking up, the existing three-dimensional jacks used for bridge deflection correction can only adjust the displacement in the front, rear, left, and right directions in the horizontal direction, and realize the adjustment in two directions under the same tonnage. To install two push jacks, the overall size of the device is too large to meet the installation in a narrow space. At the same time, some bridges not only need to be adjusted in two horizontal directions, but also need to be rotated horizontally to adjust the working conditions. Ordinary three-dimensional The jack cannot meet the construction needs
