城市复杂环境跨公路连续梁挖孔桩施工技术研究

Study on Construction Technology of Continuous Beam Excavation Pile Across Highway in Complex Urban Environment

本文以长株潭城际铁路人民路中桥为工程背景,在城市出入主干道这种复杂环境下施工刚构连续梁桩基,最后桩基顺利完成施工,文章对施工工艺和安全管理进行了全面透彻的描述分析,为今后在城市复杂环境施工连续梁挖孔桩提供了参考依据。

In this paper,taking the middle bridge on Renmin Road along Changzhuzhou-Xiangtan intercity railway as the engineering background,the construction of rigid frame continuous beam pile foundation was carried out under the complicated environment of the main road in and out of the city.The construction technology and safety management were thoroughly described and analyzed in this paper,and the construction of pile foundation was successfully completed.It provides a reference basis for the construction of continuous beam bored pile in complex urban environment.
