伏尔加-渡罗的海水道全长361公里,基岩为上泥盆纪沉积层,岩壳为很厚的冰川沉积层,大部分都是由砾石亚粘土和冰水砂构成。 水道上建有五座水利枢纽,共有7座船闸、5个土坝、20个防水堤和5个溢洪道,3座水电站。 船闸水头除6号闸为17.20米外,其余都为13.25～13.50米。所有船闸的闸首都是整体重力式钢筋混凝土结构。闸室型式除4、5号闸为坞式外,其余都为分离式。船闸的主要结构件是定型化的。所有船闸均采用头部输水系统。
The volcanic-dura seaway is 361 km long. The bedrock is a sedimentary upper Devonian deposit. The rock crust is a thick glacial sediment, mostly composed of gravelly loam and ice-water sand. The waterway has built five water conservancy hubs, a total of seven locks, five earth dams, 20 watertight embankments and five spillways, three hydropower stations. In addition to the lock on the 6th gate is 17.20 meters for the gate, the rest are 13.25 ~ 13.50 meters. The gates of all ship locks are monolithic, gravity-reinforced concrete structures. In addition to gate type gate No. 4,5 gate for the dock-style, the rest are separated. The main structural parts of the lock are finalized. All locks are used head water delivery system.
