在乌江渡水电站导流底孔的改建工程中,我们使用了圆形隧洞液压模板台车。实践证明,该台车的技术经济效果良好,它不仅适用于圆形隧洞的衬砌工程,而且改装后也可用于圆拱直墙断面的隧洞衬砌施工中。圆形隧洞液压模板台车是由卷扬机牵引,通过液压系统来控制模板的升降。台车的施工步骤是先浇筑圆形底孔的下半部分,待下半部
In the reconstruction project of the diversion bottom hole of Wujiangdu Hydropower Station, we used the circular tunnel hydraulic template trolley. Practice has proved that the trolley technology and economic effect is good, it is not only applicable to the lining of circular tunnel lining project, but also can be used after the modification of circular arch straight wall tunnel lining construction. Circular tunnel hydraulic template trolley traction by the winch, through the hydraulic system to control the template up and down. The construction step of the trolley is to pour the lower half of the circular bottom hole to be the lower half
