Incremental launching construction method applied to variable-height curved beam
The invention relates to an incremental launching construction method applied to a variable-height curve beam, which comprises the following steps of: controlling a walking type incremental launching system to jack up a beam body firstly through a multi-linkage intelligent control system, then moving forwards and falling down, then supporting by a vertical variable-height supporting system, and then continuously jacking up the beam body by the walking type incremental launching system; at the moment, the beam height of the beam body changes along the pushing longitudinal path, after the beam body falls down, the jack of the vertical height-variable supporting system correspondingly descends at the corresponding position, and the balance of the main beam is maintained. And meanwhile, a vertical lifting system and a transverse deviation correction force transmission system of the transverse deviation correction device apply different horizontal forces to the main beam along with advancing of the pushing, transverse deviation correction of the curve beam is completed, coordinate programs are set in advance in the whole process, automatic control is achieved, and therefore intelligent pushing operation of the whole variable-height curve steel box beam is completed. The large-span variable-height curve steel box girder incremental launching construction method has the advantages that incremental launching construction of the large-span variable-height curve steel box girder is achieved, and the method has good applicability to bridges crossing complex water areas and roads.
本发明涉及一种应用于变高度曲线梁的顶推施工方法，通过多联动智能控制系统控制步履式顶推系统率先将梁体顶起，之后向前移动落下，再由竖向可变高度支撑系统支撑，之后继续由步履式顶推系统将梁体顶起，此时梁体的梁高沿顶推纵向路径发生变化，梁体落下后在对应位置，竖向可变高度支撑系统的千斤顶对应降低，维持主梁的平衡。同时横向纠偏装置竖向升高系统和横向纠偏传力系统随着顶推的前进，向主梁施加不同的水平力，完成曲线梁的横向纠偏，整个过程提前设定坐标程序，自动化控制，从而完成整个变高度曲线钢箱梁的智能顶推作业。本发明的优点是：实现了大跨度变高度曲线钢箱梁的顶推施工，对于跨越复杂水域、公路的桥梁，有着很好的适用性。
