Construction of a lock at the Bagaevsky Hydroelectric Complex was started

Construction of Lock Mooring and Guiding Jetties

To ensure navigation on the Don River, STG GC builds the Bagaevsky Hydroelectric Complex in the Rostov Region, which is a transport infrastructure facility important for the whole country. The hydroelectric complex will primarily solve the problem of ensuring the required overall dimensions of the water way with a depth of at least 4 metres.

This goal will be achieved by means of the spillway dam and earth fill dam currently under construction, which are part of the hydroelectric complex. These structures will help form an artificial water basin in the river valley. Herewith, the river will have different water levels divided with dams. The navigation lock will ensure lifting and lowering of the vessels (the so called “lockage”) between the river sections with different water levels.

The Bagaevsky Hydroelectric Complex (BHC) includes a chamber, and mooring and approach channels. The chamber of a lock is its middle part with gates at the ends. It is in the chamber that the lifting or lowering of a vessel occurs, when the vessel transits from one water level to another one.

Project of BHC Spillway Dam and Navigation Lock 

When building the BHC, the construction was launched for the mooring and approach channels that will ensure not only a convenient entrance for vessels, but their moorage while in wait for lockage. The guiding jetties represented by walls of mooring and approach channels are built for smooth entrance of vessels into the lock chamber. Walls are made of Larssen sheet piles* L5-UM. 78 pieces were loaded as of today. Sheet piles are submerged to the depth of 16 m.

*Larssen sheet pile is a metal shape representing a groove with rounded edges of side walls or with locks.

Project background:

The Bagayevsky Hydroelectric Complex is the most important infrastructure project not only for the Rostov region, but also for the whole country. The hydroelectric complex under construction will be composed of a shipping lock with a central control room, upper and lower approach channels with mooring-guiding structures, a spillway and earth fill dam, a meandering fish bypass and spawning channel and a fish passage lock, industrial, service, engineering and auxiliary facilities, and housing for operating personnel. To ensure the navigation safety, channel-regulating dams are being constructed, as well as shore protection dams that will prevent the development of bank erosion processes (washout and collapse), protect from the impact of ship waves and reduce the negative impact of waters on the population living in these areas. In order to ensure guaranteed waterway dimensions (depth – 4 m, width – 80 m, bending radius – 500 m) in the section from the Kochetovsky Hydroelectric Complex site at km 3004.5 of the waterway of the Integrated Deep Water System (IDWS) to the Bagaevsky Hydroelectric Complex site at km 3089 of the IDWS waterway, dredging and river cut-off are envisaged.
