摘要
矩形顶管工艺作为一种新型施工技术,被广泛用于城市中心区内地下过街通道的暗挖施工。文章针对水西门地下过街通道的矩形顶管顶进中遭遇障碍物导致顶管机刀盘损坏的案例,通过细致的论证、研究、反思,详细阐述该工程难点的处理情况。
As a new construction technology,rectangular pipe jacking technology was currently widely used in tunneling construction of underground pedestrian passageway for urban center. During underpass rectangle jacking in Nanjing Shuiximen Street, it encountered obstacles, which resulted in the damage of pipe jacking machine cutterhead. This paper expounded relevant treatment measures in detail, which could be taken as reference for similar projects.
