Construction of a section of the Lakhtinsko-Pravoberezhnaya metro line has begun in St Petersburg
Driving of the section of the running tunnel has begun on the extension of the Lakhtinsko-Pravoberezhnaya line of the St Petersburg metro.
St Petersburg Metrostroy has begun the construction of a right-wing distillation tunnel, which will connect the station under construction “Theatralnya” with the existing station “Spasskaya.”
The work is carried out with the use of the “Petrovna” shield passing complex, which has already built a left distillation tunnel. The equipment was manufactured at the Skuratovsky Experimental Plant in Tula.
The shield was named after the founder of St. Petersburg Peter the First and reflects the good passing tradition of appealing to each other by fatherhood. As you know, all tunneling machines in Russia and the world are called exclusively female names.
The length of the construction site is about 800 meters, the diameter – 5.63 meters. According to the project, “Petrovna” will reach almost to the station “Spasskaya” where it will be dismantled and the tunnel built is issued back. The passage of the remaining section and the failure with the existing subway tunnel will be done manually.
At the same time, the middle station tunnel of the “Theatralnya” station is also being tunneled. The tunnel has a small length, so for its construction, as well as for the construction of a side station tunnel, the shield is not used, the passage is carried out by hand with the help of jackhammers and block layer.
