Problems solved by technology
[0004] For the construction of the first abutment, the abutment is hoisted on the abutment. After the construction of the first abutment is completed, the bridge erecting machine will build the next abutment based on the first abutment. During this process, the outriggers of the bridge erecting machine will be supported on the first abutment. Because the abutment surface is not flat, it will have an impact on the levelness of the machine body, which in turn will affect the construction efficiency and quality of the subsequent abutments.

The invention discloses a horizontal positioning structure, a segment assembly bridge girder erection machine and a construction method of the segment assembly bridge girder erection machine, and mainly aims to improve and optimize the problems of poor position levelness and difficulty in leveling in the construction process of the bridge girder erection machine. The stable levelness of the machine body can be well judged, then corresponding regulation and control are conducted according to the actual deflection condition, then the locking assembly and the locking auxiliary part are used in cooperation, the leveled horizontal state of the machine body can be locked, the regulation and control stability of the machine body is improved, convenience is brought to work of constructors, and the working efficiency of the constructors is improved. And finally, construction quality and construction efficiency are improved, and overall economic benefits are guaranteed.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a horizontal positioning structure, a segment assembling bridge erecting machine and a construction method thereof. Background technique [0002] Bridges refer to buildings built for roads to cross natural or artificial obstacles, so that vehicles and pedestrians can pass smoothly; bridges are generally composed of superstructure, substructure and auxiliary structures. The superstructure mainly refers to the bridge span structure and supports. system; substructure including abutments, piers and foundations. [0003] For the construction of bridges in the prior art, the segmental assembling bridge erection machine is usually used for construction. After the piers are constructed, the segmental assembling bridge erecting machine builds the abutments on the piers one by one, and then the construction personnel carry out the subsequent stages. processing work. [0004...
