  16. Railways corridors Railways corridors

  17. Railways corridors Railways corridors Modernization of the 1st railway corridorMlčechvosty tunnel face – approach retaining wall from reinforced soil Modernization of the 1st railway corridor rehabilitation of Mariánská skála Modernization of the 2st railway corridorBřeclav - Hodonín – landslide rehabilitation

  18. Possible contributions of SG - Geotechnika, a.s. to the improvement of the competitivness of the Group Special technologies • Reinforced soil structures • Matematical modeling of geotechnical problems • In situ testing and measurement

  19. Special technologies - VELKÁ VRANČA - HRDINKA ROAD Special technologies - VELKÁ VRANČA - HRDINKA ROAD • Activities • design of reinforced embankments • design of spacing and length of nails • supervision over formations execution • operative modifications • of reinforcement according to local conditions • installation of extensometers for geosynthetic reinforcement stretching monitoring • evaluation and interpretation of measurements

  20. Kněžice - Bridge Reconstruction • Activities • construction-technical survey preparation • construction design preparation • execution of works

  21. Chabařovice - Landfill Chabařovice - Landfill Project Description Expert assessment of Chabařovice landfill deformations and rehabilitation measures proposal Activities • additional IG survey • stability and deformation assessment of the northern slopes of the landfill • design of slope securing in several variants - pile wall, stabilizing fill

  22. Possible contributions of SG - Geotechnika, a.s. to the improvement of the competitivness of the Group In situ measurement • Tunnel monitoring • Georadar • Laser scanner • Database monitoring system BARAB

  23. D8 Motorway – Panenská Tunnels D8 Motorway – Panenská Tunnels • Activities • complex geo-monitoring • geological documentation of faces • convergence and extensometric surveying • geodesic surveying of portals and surface subsidence • measurement of stress in primary lining • measurement of tension at the rock primary lining interface • surveying of primary and secondary lining shape • surface objects passportization • geotechnical supervision • consulting services for the investor
