LVOLOKALAMSKY TUNNEL UNDER MOSCOW CANAL IN MOSCOW, RUSSIA

Length of tunnel section without expansion joint is 160 m.
First ever in Russia tunnel under the channel with a length of 160 m long was fulfilled without application of any expansion joints.
Construction works were managed to be completed within two navigation periods started from December 1999 up to April 2000. Welded sheet piling PШС-60 (Russian Standard) were implemented together with tubes of Ø1,200 mm for foundation ditch reinforcement. Tunnel was designed as a curved structure. For construction purposes two trolleys were applied located above sheet piling within 30m.
First trolley was used for two cranes of 20 & 50 tons carrying capacity, to insure total site assembling works procedures. The second trolley was used to deliver materials. The pump was installed on the trolley as well for concreting purposes. Trolleys were accommodated with electrical power.
