Cast-in-place arch bridge combined support structure and construction method thereof
The invention discloses a cast-in-place arch bridge combined support structure and a construction method thereof. The cast-in-place arch bridge combined support structure comprises at least three bottom pile sets transversely crossing a riverbed, and connecting joints are arranged between bottom piles of the same bottom pile set. A longitudinal inverted T-shaped groove and a longitudinal square through groove are formed in the top of the bottom pile; the device further comprises a first support, and the first support is in an inverted trapezoid shape. The first support end extends out of the bottom pile; a longitudinal I-shaped bearing beam is also arranged above the first support and is fixedly connected with the bottom pile; the bottom piles are connected with a steel platform bridge deck located on the upper surfaces of the longitudinal distribution beams through the longitudinal I-shaped bearing beams, the bailey beams and the longitudinal distribution beams. The steel platform bridge deck slab is connected with the main arch ring through a bowl buckle type scaffold; the combined support structure is clear in stress, convenient to assemble and disassemble, capable of being recycled for multiple times, capable of reducing the erection height of the bowl buckle support, small in influence on a riverbed, small in influence on flood control safety and remarkable in ecological environmental protection and social and economic benefits.
本发明公开了一种现浇拱桥组合支架结构及其施工方法，包括至少三组横向跨越河床的底桩组，同一底桩组的底桩之间设有联系结；在底桩顶部设有纵向倒T形槽及纵向方形通槽；还包括第一牛腿，所述第一牛腿为倒置的梯形；第一牛腿端伸出底桩；在所述第一牛腿上方还设有纵向工字承重梁，与底桩固定连接；所述底桩通过纵向工字承重梁、贝雷梁及纵向分配梁与位于纵向分配梁上表面的钢平台桥面板连接；所述钢平台桥面板通过碗扣式脚手架与主拱圈连接；组合支架结构受力明确，安拆便捷，可多次循环使用，可降低碗扣支架搭设高度，对河床影响小，对度汛安全影响小，生态环保及社会经济效益显著。
