松山引水工程位于吉林省抚松县境内， 挡水建筑物为面板堆石坝， 总库容１３３ 亿ｍ３ ， 通过长１２６ ｋｍ 的引水隧洞引水至小山水库。大坝施工导流采用一次断流、隧洞导流方式。在施工中对导流明渠、隧洞洞身结构、冲沟治理等部位进行设计优化， 从而加快了施工进度， 提前完成工程导截流， 并为工程建设节省投资１００ 多万元。
The Songshan Diversion Project is located in Fusong County, Jilin Province. The water retaining structure is a concrete facing rockfill dam with a total storage capacity of 133 million m3. The diversion tunnel with a length of 12.6 km leads to Xiaoshan Reservoir. Dam construction diversion using a cut-off, tunnel diversion. In the construction of the diversion channel, tunnel body structure, gully management and other parts of the design and optimization, thus speeding up the construction progress, ahead of completion of engineering diversion and closure, and construction investment savings of about 1000000 yuan.
