乌坑坝隧道衬砌台车洞内拆除及安装技术

Demolition and installation technique in a cave of lining trolley in Wukengba tunnel

随着我国隧道施工技术的不断提高 ,衬砌台车已经成为必不可少的施工设备 ,一般情况下 ,衬砌台车的拆除与安装均在洞外完成 ,或在洞内进行破坏性拆除 ,造成不少浪费 ,结合具体工程实例 ,介绍了京珠高速公路粤境北端乌坑坝隧道衬砌台车洞内拆除及安装的过程及难点 ,不仅节约了成本 ,而且加快了施工进度 。

With the development of China tunnel construction technique, lining trolley is already the necessary construction equipment. In a common condition, demolition and installation of a lining trolley is all finished out of cave ,or damaging demolition of it is done in cave, these lead to much waste. Combining with the concrete engineering example, the paper introduces the process and difficult points of demolition and installation in a cave of lining trolley in Wukengba tunnel of Jingzhu expressway in the north of Yue area, it not only saves cost but also speeds up rate of advance. It is worth spreading.
