渠道衬砌施工是大型调水工程所关注的重点及难点,其中尤以渠坡衬砌最为关键。以南水北调中线干线河南段工程为依托,从工序开始,将渠坡衬砌分解为渠床整理、永久排水系统、砂砾石垫层、保温板、复合土工膜、衬砌混凝土以及伸缩缝等关键工序,并分析了各工序的施工方法,为渠坡衬砌的规范化施工提供参考。 Channel lining construction is the focus of large-scale water diversion projects and difficulties, especially in the most important slope slope lining. Based on the project of Henan section of the middle route of South-to-North Water Diversion, from the beginning of the process, the drainage slope lining is decomposed into key processes such as canal bed arrangement, permanent drainage system, sand and gravel cushion, thermal insulation board, composite geomembrane, lining concrete and expansion joints The construction methods of each process are analyzed, which can provide references for the standardization of drainage slope lining.
