乌江彭水水电站导流洞第一标段洞身混凝土施工技术

Concrete construction technique for lining of diversion tunnel(No.1 tender section) of Pengshui Hydropower Station on Wujiang River

在乌江彭水水电站导流洞第一标段洞身混凝土衬砌施工中采用了自制移动式钢筋台车,实现了大型断面的钢筋安装,并采用移动式全断面钢模台车、移动式半断面钢模台车、人工立模等工艺进行了混凝土衬砌中模板的施工以及大型马蹄形断面的导流洞混凝土衬砌,加快了施工进度、提高了施工效率,降低了施工成本,增强了施工的安全性,因而可在类似工程中推广。

During the construction of the concrete lining for the diversion tunnel （ No. 1 tender section） of Pengshni Hydropower Station on Wujiang River, the reinforcement assembling for large section is realized with a kind of self-made movable trolley for the assembling. Moreover, the technologies of movable full-section and half-section steel formwork carriers and manual formwork erection, etc. are also applied to the construction of formwork for the concrete lining and the concrete lining for the large Ushaped section of the tunnel with quickened construction progress, enhanced construction efficiency, lowered construction cost and higher construction safety, which can be widely popularized to the similar projects concerned.
