贝雷梁在白洞天坑垂直观光电梯人员通道施工中的应用

The Application of Bailey Beam in the Construction of the Personnel Passage of the Baidong Tiankeng Vertical Observation Elevator

白洞天坑垂直观光电梯位于天坑底部,天坑四周为悬崖,受限于地形条件及景区环境保护要求,施工人员无法下到127 m深天坑底部作业。为保证人员正常上下,现场在天坑顶部搭设悬挑18 m长贝雷梁平台,通过平台前端安装的施工吊篮作为人员上下升降设备,成功解决白洞天坑垂直观光电梯施工人员上下问题,为贝雷梁在大跨度和特殊项目中的应用提供新的思路。

The Baidong Tiankeng vertical sightseeing elevator is located at the bottom of the Tiankeng surrounded by cliffs,due to the terrain conditions and environmental protection requirements of the scenic spot,construction personnel cannot go down to the bottom of the 127m deep Tiankeng to work.In order to ensure the normal up and down of personnel,a cantilevered 18m long bailey beam platform was set up on the top of the Tiankeng,and the construction basket installed at the front of the platform was used as the personnel up and down equipment to successfully solve the problem of vertical sightseeing elevator construction personnel in Baidong Tiankeng,the application of bailey beam in large-span and special projects provides new ideas.
