Services

Tonnelstroy SCID OJSC is in charge of construction of municipal and industrial manifolds using tunneling shields at a depth of 15 – 40 m in soils of strength category I-IV, construction and repair of shafts at operating facilities, making punctures under existing buildings and structures, ducts for laying cables, small-diameter pipes. The company has experience in construction of pedestrian subways using the shield and rock tunneling methods, passages under residential buildings, hydraulic engineering structures and main line metro tunnels, automobile tunnels.

The Directorate is engaged in construction of various-purpose vertical underground structures: reservoirs, settling tanks, reservoirs for liquid fuel and oil products, sunken process premises, underground portions of water supply, sewerage and drainage pump stations, buried chambers for utilities, shafts of municipal and industrial tunnels.

When necessary, shield tunneling is combined with special methods – water drawdown, caisson, soil freezing, soil stabilization with chemicals. The company mastered a new advanced method of vertical underground structures construction – the caisson method.

Manifold tunnels

Tonnelstroy SCID OJSC constructs municipal and industrial manifold tunnels using tunneling shields at a depth of 15 – 40 m in soils of strength category I-IV, construction and repairs of shafts at operating facilities, punctures under existing buildings and structures, roads for laying cables, small-diameter pipes. The company is experienced in construction of pedestrian subways using the shield and rock tunneling methods, passages under residential buildings, hydraulic engineering structures and main line metro tunnels, automobile tunnels.

As to functionality, the tunnels for public utilities and industrial enterprises constructed by the shielding method are divided into:

  • Sewer Transporting sewage effluent through the tunnel and its collection from networks laid by open-cut mining
  • Water supply Water transporting through the tunnel
  • Communication Joint laying of the water supply pipelines, heating network, pressurized sewerage system, compressed air pipeline, cables etc.
  • Pedestrians Transfer of pedestrian flow under streets, squares, transport routes
  • Transport Placement of interdepartmental transportation lanes (conveyor lines, rollers etc.)
  • Drainage Underwater revetment through lining, drainage water collection from filters and transportation.

Vertical Underground Facilities

The Directorate is also engaged in construction of various-purpose vertical underground structures: reservoirs, settling tanks, reservoirs for liquid fuel and oil products, sunken process premises, underground portions of water supply, sewerage and drainage pump stations, buried chambers for utilities, shafts of municipal and industrial tunnels.
When necessary, shield tunneling is combined with special methods – water drawdown, caisson, soil freezing, soil stabilization with chemicals.
The company mastered the new advanced method of construction of vertical underground structures – the caisson method.

Vertical Underground Structures

  • During the construction period, the shafts serve for assembly and disassembly of shielding complexes, soil excavation, taking people down and up, change of the shields’ movement direction.
  • For the operation period, the shafts are arranged as inspection manholes.
  • The sewer tunnel shafts serve for transfer of sewage effluents from networks laid by open-cut mining.
  • The communication tunnel shafts accommodate pipelines, stairways, ventilating units, pump stations etc.

Since June 2009, Tonnelstroy SCID OJSC is the general contractor of the Metro construction in Kharkov
