Improvement of tunnel boring machine S-782 cutter head

The Saint-Petersburg Metro needs advancement, which necessitates increasing the tunnel boring rate and enhancing the tunneling safety. The article discusses operation of tunnel boring machine S-782 in double-track tunneling at a diameter of 10.3 m in difficult geological conditions of the city of Saint-Petersburg. The accidents in operation of the equipment are described. Upgrading of the tunneling shield using vibroactive rolling cutters is considered, and the forces on the rolling cutters and the parameters of the vibrators which set the rolling cutters in motion are calculated. The upgrading idea of the cutter head tools consists in using a new type of rolling cutters; the possible design of driving mechanisms is searched for. The upgrading of the shield with replacement of passive cutters by vibroactive cutters is described, and the potential design of the tools is presented graphically. It is proposed to set the vibroactive cutting rollers in motion using the pneumatic and electromagnetic vibrators. The elevation view of the tunneling shield with the proposed upgrades is shown. The use of the vibroactive tools can reduce the risk of disastrous wear of rock cutters, as well as the number and duration of accidentcaused downtime, as a consequence, and can enhance capacity of the tunnel boring machine.

Keywords: tunnel boring machine, metro, limestone, disc rolling cutters, cutter picks, unbalanced system, vibrator, tunneling rate.
