Miatlinskaya HPP, Part 2

Posted on January 12, 2012 by

First, we would like to remind you that Miatlinskaya Hydropower Plant is a part of the Dagestan branch of RusHydro. It is located on the Sulak River between Chirkeyskaya HPP and Chiryurtskaya HPP. Its water reservoir is also used as a water supply source for Makhachkala and Kaspiysk. Its installed capacity is 220 MW.

This road leads to the HPP.

A typical view of the lower constructions of the HPP: the building of the HPP, open switchgear, surge chamber.

The cabin of a bridge crane.

The machinery hall. The floor is dirty because they have just finished major repairs of one of the units.

Inside one of the hydraulic units and lower rooms of the HPP building.

The control center.

The shift on duty.

Near the HPP building, there is this ascetic summerhouse. It was made for workers of the HPP to take a swim from to cool down because in summertime temperature may reach +40C.

The Sulak’s water is turquoise and the deeper it is, the more rich its color gets. It is the river’s natural color, by the way. No Photo Shop editing.

A long automobile tunnel connects the HPP building and the dam. Miatlinskaya HPP’s dam is arch. In Russia, there are just three arch dams and all of them are located in Dagestan.

Initially, it was to be a barrage power station. However, after a massive landslide on the right bank of the Sulak River in 1997, construction works of the HPP were held up. They also had to change the project and as a result, the building of the HPP was moved aside by 1.5 km.

For some reason, the territory of the HPP is full of dead swifts and they definitely were not winged.

The dam’s height is 86.5 m (comparable to a 30-storeyed building). Its length is 179 m.

Usually, it is cloudy here which makes it difficult to see the color of water. By the way, the reservoir is 70 m deep and contains 47 million m3 of water (which is relatively small).

Still, when clouds disperse, you can see this:

To the right of the dam, there is a loading platform. It is used for carrying heavy equipment such as metal constructions, transformers, etc.

Near the dam, there is an intake channel.

A hydrofoi.

The dam is not a solid construction, as some of you may think. It has a lot of tunnels, galleries and passages on the inside. It is equipped with all kinds of sensors, pumps and other devices monitoring the dam. They can also add concrete where necessary.

Let’s go back to the surge chamber.

They are used to limit pressure rise and fall when necessary.

It’s getting dark…

And we go back to the summer.

    the construction projects of russia are large and i am sure required considerable work, but the observed quality of the poured concrete always looks to be of substandard. ‘cold’ joints, poorly consolidated concrete, etc. how long before a major failure?
