危岩体防治工程中物料提升架的设计和应用

Design and Application of Material Hoisting Structures in Controlling Engineering for Dangerous Rockmass

本文讨论了三峡链子崖危岩体防治工程中的垂直运输设备，用碗扣式脚手架搭设的８２．６ｍ高物料提升井架，通过对单立杆承受荷载的计算，整体稳定性分析和荷载试验，证明该物料提升架达到设计要求，能很好地满足施工需要。

This paper discusses about the vertical transportation equipment used in the control projects on Lianzi′ai dangerous rockmass of the Three Gorges, i.e.the 82.6 m high material hoisting structures constructed from scaffold with cuplock joint. After calculation of load applied on the single vertical lever, analysis of integrated stability as well as load test, the hoisting structures are proved to satisfy the design requirements.
