鲁班水库位于四川省三台县,是都江堰灌区干渠上一座能蓄水2.78亿m~3的囤蓄水库。其主坝为钢筋混凝土防渗面板干砌条石坝,坝高68m,坝长315m,为目前我国已建同类型坝最高的一座。坝的正常蓄水位460m,坝顶高程462m。面板厚度为0.3～0.5m,面积1.2万m~2。面板下游侧设有厚0.5m的素混凝土主垫层和1.2m厚的浆砌条石副垫层,面板与垫层间铺沥青油毛毡,使面板能较自由地滑动。坝的上游坡
Located in Santai County, Sichuan Province, Luban Reservoir is a reservoir reservoir capable of storing 278 million m ~ 3 of trunk canal in the irrigation area of Dujiangyan. The main dam is reinforced concrete impervious panel dry-laid stone dam, dam height 68m, dam length 315m, for the present our country has built the highest type of dam. Dam’s normal water level 460m, crest elevation 462m. Panel thickness of 0.3 ~ 0.5m, an area of 12000 m ~ 2. The downstream side of the panel is provided with a prime concrete cushion of 0.5m thick and a parafilter with a thickness of 1.2m and a bitumen oil felt between the panel and the cushion so that the panel can slide freely.
