Earthwork

In the arsenal of technology that Stroytransgaz employs for earthwork, there are both classical construction methods and those using modern technical resources for digging trenches.

During construction of the Sougueur-Hadjret Ennous gas pipeline in Algeria, we equipped the work site with contemporary, high-performance machinery for continuous operation: Trencor 1660 HDE trench excavators and Superior-350,2 padding machines for bed preparation and laying and padding the pipeline.

When trenching in permanently frozen soil, Stroytransgaz uses rotary excavators.

During construction of the second line of the Zapolyarnoe-Urengoy main gas pipeline and construction of the Zapolyarnoe field, we used ETR-309 rotary excavators from the Irmash (Bryansk) factory.

During construction of the Purtasov compressor station—part of hydrocarbon field development in the Far North—we pioneered in that region the use of turbine generator foundations prepared with reinforced concrete (in combination with hot-air heated enclosures, hot-air heating, and PENOPLEX to safeguard the permafrost from thawing).

During construction of facilities for the industrial complex, Stroytransgaz uses technologies of piling work and building solid-cast foundations. For construction of the Yugo-Zapadnaya cogeneration plant in St. Petersburg, we used a pile foundation; and for the Khakassy aluminum plant, we used solid-cast foundations.
