南水北调中线引调水工程是我国在建的一项宏伟工程,一期输水工程全长1421km,全线大部分采取明渠形式输水。渠道采用铺设土工膜、衬砌混凝土面板等措施解决沿渠防渗等问题,为了保证施工质量,必须提高施工技术水平,加强各施工工艺流程的现场管理。以下结合南水北调工程一期河南安阳段九标的工作经历,简要探讨一下梯形断面防渗渠道内边坡混凝土衬砌施工的作业内容及主要施工工序的控制。
The Middle Route of South-to-North Water Diversion Project is a grand project under construction in China. The first phase of the water diversion project has a total length of 1421km, and most of the entire line adopts the open channel to deliver water. Channels such as geomembrane laying, lining concrete panels and other measures to solve the seepage along the canal and other issues, in order to ensure the construction quality, we must improve the level of construction technology and strengthen the construction site management of process flow. The following combination of a South-to-North Water Diversion Project Henan Anyang nine standard work experience, a brief discussion of trapezoidal cross-section seepage canal concrete lining construction work content and main construction process control.
