摘　　要：在大纵坡、长斜井施工中混凝土输送方式的选择的显得尤为重要。云南滇中引水工程大理Ⅰ段2标施工支洞坡陡、水文地质复杂,工作空间狭小,混凝土施工难度大,为了解决混凝土施工质量,采取自行爬模行走、锁定、混凝土输送方式和施工缝面等处理措施,较好地解决了长斜井混凝土施工所面临的常规问题,并由此对长斜井混凝土施工积累了一定的经验。The selection of concrete conveying mode is particularly important in the construction of large longitudinal slope and long inclined shaft.With steep slope, complex hydrogeology, narrow working space and difficult concrete construction, the construction branch tunnel of Dali Section Ⅰ and Bid 2 of the water diversion project in Yunnan Province is constructed.In order to solve the quality of concrete construction, measures such as self-climbing formwork walking, locking, concrete conveying mode and construction joint surface are adopted, which preferably solves the routine problems faced by the long inclined shaft concrete construction and accumulates certain experience for the long inclined shaft concrete construction.
