UNDERGROUND WALKWAY
Reinforced concrete lining fabrication in underground walkway under a railway was performed. 55 m3 of 100 mm thick В30F300W10 shotcrete were placed. The working conditions were not light: mixture supply range was 150 meters, tunnel was located under four railway tracks, trains caused constant vibration of shotcreting surface. According to the project tunnel walls were covered with waterproofing layers and poorly reinforced, but it did not prevent successful task completion.
