宫山嘴水库重建工程导流明渠施工方案分析

Analysis on diversion open channel construction plans in Gongshanzui Reservoir reconstruction project

宫山嘴水库重建工程拟采用明渠导流,导流明渠边坡及围堰地质条件较差,给工程施工造成了较大困难。结合工程设计及实际情况,对施工设计进行了适当的优化,使导流明渠在规定时限内顺利完工,为整个重建工程的顺利实施,特别是如期实现截流创造了有利条件。本文对施工中导流明渠边坡以及纵向围堰的具体施工方案作了分析,得出的结论对同类工程具有一定的参考价值。

Open canal flow diversion is adopted in Gongshanzui Reservoir reconstruction project.Flow diversion open canal slope and cofferdam have worse geological conditions,thereby leading to larger difficulties to project construction.Project design and practical condition are combined for suitably optimizing construction design.Therefore,flow diversion open canal can be smoothly completed within regulated time,and beneficial conditions are created for smoothly implementing the whole reconstruction project and especially realizing interception on schedule.In the paper,concrete construction plan of flow diversion open canal slope and longitudinal cofferdam in construction are analyzed,and the obtained conclusion has certain reference value for similar projects.
