复杂环境中的地下暗埋箱涵拉顶式施工技术与应用

Jacking-pulling Construction Technology for Underground Box Culvert in Complex Environment and the Application

结合上海轨道交通2号线东延伸段工程张江高科站工程实例,详细介绍了地下暗埋箱涵拉顶式施工新技术,该技术具有可在工作面积狭小的环境条件下施工、施工对环境影响较小、导向精度高等优点,其工艺是现代顶管施工技术的一种创新和补充,是非开挖地下箱涵施工的一种新的技术手段,为复杂环境下的地下空间开发利用提出了新的解决方案。

Combined with an engineering example of Shanghai rail transit line 2,the paper introduces a new jacking-pulling technology for underground box culvert,which has advantages of convenient working in narrow area and light environmental impact with high guiding accuracy.This technology is an innovation and supplement to modern pipe jacking construction and a new technical means to underground box culvert construction by trenchless technology and provides solution to development and utilization of underground space in complex environment.
