Steel truss girder multi-point traction type incremental launching construction system and construction method thereof
The invention relates to the technical field of constructional engineering, in particular to a steel truss girder multi-point traction type incremental launching construction system and a construction method thereof.The steel truss girder multi-point traction type incremental launching construction system comprises an incremental launching traction system used for steel truss girder engineering traction general control, instrument allocation and sub-package type issuing of engineering tasks; The system further comprises a jack master control terminal and a traction steel strand coefficient calculation unit. The jack master control terminal is used for controlling a plurality of continuous jacks to synchronously pull and move forwards, and providing a power source for a steel truss girder to reach a design coordinate; The traction steel strand coefficient calculation unit is used for calculating the optimal number of strands of traction steel strands and is responsible for connecting each jack. The steel truss girder and the support are stressed more reasonably by adopting multi-point traction, overlarge stress of a single point is avoided. Meanwhile, the multi-point traction girder body is stable in sliding, the advancing track of the curve bridge is easier to control. The problems that the rigidity of the bottom surface of the lower chord of the steel truss girder is changed, the bearing force is not uniform, and the curved bridge pushing advancing track is not easy to control are solved.
本发明涉及建筑工程技术领域，具体涉及钢桁架梁多点牵引式顶推施工系统及其施工方法，包括：顶推牵引系统，用于钢桁架梁工程牵引总控，调配器械，对工程任务进行分包式下发，包括千斤顶总控终端和牵引钢绞线系数计算单元：千斤顶总控终端，用于控制多台连续千斤顶同步牵引前移，为钢桁架梁提供动力源，到达设计坐标；牵引钢绞线系数计算单元，用于计算牵引钢绞线最佳用量股数，负责连接各台千斤顶，本发明采用多点牵引使钢桁架梁和支架受力更加合理，避免单点受力过大，同时多点牵引梁体滑移平稳，更易控制曲线桥行进轨迹，并且解决了钢桁架梁下弦杆底面刚度变化、承受力不均的问题和曲线桥顶推行进轨迹不易控制的问题。
