Stroytransgaz Group's first own inflatable hangar

Stroytransgaz Group of Companies mounted the first in-house inflatable repair workshop (hangar) at the construction site of Bagaevskiy hydroelectric complex to ensure comfortable conditions during the winter and optimize repair work. The inflatable hangar is cold resistant (as low as minus 50°C). When it is 30 degrees Celsius below zero, the temperature inside will be maintained at about ten degrees Celsius, making it comfortable for mechanics to work in the winter.

The construction site of the hydroelectric facility is located at a great distance from populated areas, and any repair of equipment requires renting a repair workshop and having mechanics and equipment sent there. In addition to financial costs, it leads to increased machinery downtime and loss of working time. After the erection of the hangar, most of the routine repair and maintenance of dump trucks, passenger cars and some special equipment will be done in-house at the construction site. The hangar of 20 x 20 m and a height of 12 m can accommodate up to four vehicles at a time.

The advantage of the hangar is easy erection. There is no need for a foundation, you only need to free the site from the foreign objects. The hangar is cost-effective in use. The automation system monitors the pressure inside the air cylinders and switches on the supercharging system if needed. At the same time, the power consumption is only 3.5 kWh.

Also, the advantages of using inflatable hangars include their mobility and that they do not require routine maintenance. Upon completion of the hydroelectric facility, the hangar will be moved to another company site. In the case of mechanical damage by machinery, the repair can done on site by own efforts with a repair kit.

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, a settlement for operating personnel. To ensure the navigation safety, channel-regulating dams are arranged, 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 Unified Deep Water System (UDWS) to the Bagaevsky Hydroelectric Complex site at km 3089 of the UDWS waterway, dredging and river cut-off are envisaged.
