小直径大曲率隧道二次衬砌拱墙台车的设计

Design of Arch Wall Trolley for Secondary Lining of Small-diameter and Large-curvature Tunnel

依托武汉大东湖核心区污水传输系统工程,研究了一种小直径大曲率隧道高适应性的可通行、可多作业面跳仓施工的拱墙台车。在工程实际应用中,用时不到3个月就完成了最长3.6 km区间的二次衬砌施工,施工效率高、质量好,可在类似项目中推广。

Based on the sewage transmission system project in the core area of Wuhan Dong Lake,a kind of arch wall trolley with high adaptability is studied for small-diameter and large-curvature tunnel,which can be used for alternative bay method construction with passable and multiple working faces.In the practical application of a project,the secondary lining construction of the longest 3.6 km section is completed in less than 3 months.It has high construction efficiency and good quality,and can be popularized in similar projects.
