Kanonersky tunnel (Template:Lang-ru[3]) is a tunnel under Sea canаl in Kirovskiy Distrikt of Saint-Petersburg. It is from outside Gutuevsky island to it approaches Dvinskaya street to Kanonersky Island, White square.
Overview
Till 1983 on island it was possible to get on the ferry (it was last ferry line of Saint Petersburg) or a private boat[1], daily through Sea canаl it was crossing more than 2 million peoples.[4]. Because of that on the Sea channel movement of courts sea-gauge to 10 metres (33 ft) and width to 40 metres (130 ft), bridge building have refused. The decision to build a tunnel was accepted.
Tunnel built a method buried sections: in preliminary dug trench it has been laid five identical sections, each of which had length of 75 metres (246 ft) and weighed about 8,000 tonnes (8,800 short tons). The project has been prepared Lengiprotrans,[2] building carried out Giprostroymost.
After packing of designs from them have pumped out water and have built underground tunnels and portals; the full length of a tunnel has made 927 metres (3,041 ft).[1] It is constructed on two lanes (on one in each part), periodically water gets to a tunnel, experts explain it defects of a waterproofing. In 1998-2002 tunnel major repairs.[1] In 2004 Lengiprotrans again made repair work[2], in the end of June, 2009 tunnel repair again was required, the drainage system has been replaced.[5]
The tunnel is not closed on repair, but movement is essentially limited. Failures in a tunnel occur seldom and because of low speeds do without victims, but elimination of their consequences can occupy some hours.[6]
