在悬臂施工T型刚构桥梁过程中,经常会遇到需要将挂篮底篮、现浇段支架底模等重物拆除的工作,然而需要拆除的这些组合构件悬挂在几十米甚至上百米的高空,拆除操作困难、耗时较多、安全隐患大。在云南锁龙寺至蒙自高速公路南盘江特大桥施工过程中,采用液压千斤顶完成了高空卸重物的工作,现予以总结归纳,可为类似工程提供借鉴。
During the cantilever construction of T-shaped rigid-frame bridge, often need to dismantle the heavy objects such as baskets of basket baskets and bottom molds of cast-in-place supports. However, these composite components that need to be dismantled are suspended in tens of meters or even hundreds Height of rice, demolition operation difficult, time-consuming, security risks. In the process of construction from Yunnan Province, the LongLongSi to Mengzi Expressway Nanpanjiang Bridge, the use of hydraulic jacks to complete the work of high-altitude unloading heavy objects, are summarized to provide reference for similar projects.
