基　　金：中建二局三公司课题——可伸缩周转式井筒平台在电梯井道中的技术研究。

摘　　要：主要介绍超高层电梯井道中可伸缩井筒平台中应用的施工技术。经过对预埋支座、井筒平台主梁施工节点进行反复论证优化,形成一套包预埋爬锥、根据不同井道尺寸调节、操作平台整体提升等关键控制点。对可伸缩井筒平台进行深化加工试验、即可在本项目中周转使用,也能在不同项目周转,为同类工程提供借鉴经验。This paper mainly introduces the construction technology of the extendable shaft platform in the super high-rise elevator shaft.After repeated demonstration and optimization of the embedded support and shaft platform main beam construction node,a set of key control points such as embedded climbing cone,adjustment according to different well size,and overall lifting of the operating platform are formed.The further processing test of the retractable wellbore platform can be used in this project and in different projects,providing reference experience for similar projects.
