Dismantling method suitable for continuous multi-span multi-arch arch bridge structure
The invention provides a dismantling method suitable for a continuous multi-span multi-arch arch bridge structure, which comprises the following steps: firstly dismantling a first main bridge deck and a second main bridge deck of the arch bridge structure, and then dismantling a first main bridge longitudinal and transverse beam, a first suspender assembly, a second main bridge longitudinal and transverse beam and a second suspender assembly; and then the first approach bridge panel, the second approach bridge panel, the first on-arch stand column assembly and the second on-arch stand column assembly are dismantled, and finally the first main arch ring, the second main arch ring, the first side arch ring and the second side arch ring are dismantled. Heavier components such as the first main arch ring are gradually dismantled, so that the structural stability of the arch bridge is favorably kept until the bridge is dismantled, and the dismantling work can be safely and efficiently carried out.
本发明提供了一种适用于连续多跨连拱拱桥结构的拆除方法，通过先拆除拱桥结构的第一主桥面板和第二主桥面板，再拆除第一主桥纵横梁、第一吊杆组件以及第二主桥纵横梁和第二吊杆组件，然后拆除第一引桥面板和第二引桥面板、第一拱上立柱组件和第二拱上立柱组件，最后再拆除第一主拱圈、第二主拱圈以及第一边拱圈和第二边拱圈，本申请实施例中，先移除较轻的结构如第一主桥面板等，再逐步拆除较重的组件如第一主拱圈等，有助于保持拱桥结构稳定性直至拆桥结束，能够使得拆除工作安全、高效地进行。
