Single-cantilever construction bridge for V-shaped valley and construction method
The construction method comprises the steps that firstly, tunnel construction is conducted on the two sides of the V-shaped valley respectively, then a bottom plate of a tunnel portal section is excavated downwards to form a working space, pouring construction is conducted on a zero section in the working space, a balance weight section is constructed at the end, away from the V-shaped valley, of the zero section, and the V-shaped valley is constructed at the end, away from the balance weight section, of the V-shaped valley; an anchoring device is constructed on the balance weight section, and the balance weight section and the rock mass are anchored into a whole; starting from the zero sections on the two sides of the V-shaped valley, the hanging basket is used for carrying out section-by-section construction on the cantilever section; when the two cantilever sections are constructed section by section to a closure section, closure section construction is conducted; after the closure section is hardened, the hanging basket on the bridge is dismantled and then hoisted and moved out of the bridge floor; and finally, after the bridge floor is cleaned up, auxiliary engineering of the bridge is constructed, and construction of the single-cantilever construction bridge of the V-shaped valley is completed. A traditional T-shaped rigid frame bridge pier is omitted, single-cantilever pouring construction is achieved through the balance weight and the anchoring device, the span can reach 40-200 m, the construction period is shortened, and the influence on the environment is reduced.
本发明公开了一种用于V形沟谷的单悬臂施工桥及施工方法，首先对V形沟谷两侧分别进行隧道施工，然后隧道洞口段底板向下开挖，形成工作空间，在工作空间内进行零号段浇注施工，零号段远离V形沟谷一端施工配重段，在配重段施工锚固装置，将配重段与岩体锚固为一体；从V形沟谷两侧的零号段开始，利用挂篮对悬臂段分节段施工；当两个悬臂段逐节段施工至合拢段时，进行合拢段施工；待合拢段硬化后，拆除桥上的挂篮，然后吊装移出桥面；最后桥面清除干净后，对桥梁附属工程施工，完成V形沟谷的单悬臂施工桥的施工。本发明取消传统T形刚构桥桥墩，利用配重和锚固装置实现了单悬臂浇筑施工，跨度可以达到40m～200m范围，缩短施工周期，降低对环境的影响。
