摘要
某地铁车站基坑采用智能同步穿心千斤顶顺利完成滑降式支撑滑降,滑降速度超过采用卷扬机的前代产品,极大减少基坑无支撑暴露时间,更有效控制基坑变形,更重要的是利用千斤顶的智能控制系统,达到4个吊点的整体同步滑降,整体倾斜度满足要求.详细介绍了吊装系统的组成、同步系统的原理及工作过程、穿心千斤顶的布置、吊装过程,为滑降式快速支撑吊装提供参考.
Abstract
The foundation pit of a certain subway station successfully completed a sliding support sliding using an intelligent synchronous through the center jack.The sliding speed exceeded that of the previous generation products using winches,greatly reducing the unsupported exposure time of the foundation pit and more effectively controlling the deformation of the foundation pit.More importantly,the intelligent control system of the jack was used to achieve an overall synchronous sliding of four lifting points,and the overall inclination met the requirements.The article provides a detailed introduction to the composition of the lifting system,the principle and working process of the synchronous system,the arrangement of the through center jack,and the lifting process,providing reference for the sliding rapid support lifting.
