Construction method and construction device of inter-tunnel arch bridge and inter-tunnel arch bridge
The invention relates to the field of bridge engineering, in particular to an inter-tunnel arch bridge construction method and device and an inter-tunnel arch bridge. According to the construction method, a support is erected through a construction platform for building a tunnel, excavation of rock masses on the two banks can be avoided, interference to the surrounding environment is small, ecological balance and natural resources of a bridge area can be protected, and the environment protection requirement can be met; the connecting section and the arch springing section in the midspan are spliced through the platforms, with different heights, of the same support, the situation that the support is erected and spliced in a debris flow area is avoided, the second platform located below the first platform is adopted for splicing the connecting section, the splicing site can be saved, and sharing with a tunnel construction site is achieved, and due to the fact that the first platform and the second platform vertically correspond, the construction efficiency is improved. A hoisting link after assembly can be avoided, the bridge-tunnel connecting structure is more suitable for the scene of bridge-tunnel connection, the vertical rotating hinge is matched with the first inhaul cable and the second inhaul cable, connecting sections with vertical space conflicts can be installed through supports on the opposite banks, the connecting sections do not need to be anchored to rock masses on the two banks, and large hoisting equipment is also not needed.
本发明涉及桥梁工程领域，具体提供一种隧间拱桥的施工方法、施工装置及隧间拱桥，施工方法利用修建隧道的施工平台架设支架，能够避免开挖两岸岩体，对周围环境的干扰小，有利于保护桥区的生态平衡和自然资源，利于满足环保要求，跨中的连接段和拱脚段，利用同一支架的不同高度的平台进行拼装，避免在泥石流区搭设拼装支架，采用位于第一平台下方的第二平台拼装连接段，能够节省拼装场地，实现与隧道施工场地的合用，并且由于第一平台和第二平台上下对应，能够避免拼装后的吊运环节，更适用于桥隧相接的场景，通过竖转铰搭配第一拉索和第二拉索，能够将竖向空间冲突的连接段利用对岸的支架实现安装，无需锚固于两岸岩体，也无需大型吊装设备。
