In the construction of the new Baikal, special chemical solutions developed by BASF

Work on the construction of a new Baikal tunnel on the Delbichind - Daban stretch of the East Siberian Railway was completed in March 2018. The final stage was personally observed by Russian President Vladimir Putin. After the head of the Russian Railways Oleg Belozyorov reported on the readiness to complete tunneling, and Vladimir Putin gave the appropriate command on the space bridge, the tunnel shield destroyed the last meter of the rock. The work of the tunnel tunnel complex (TPK) in the construction of a new tunnel in Buryatia was facilitated and accelerated by special solutions developed by BASF, the world's leading producer of construction chemicals.

"The object was a liquid foam polymer composition that protected the steel cutting tool TPK, as well as an increase in the speed of penetration while reducing the torque on the rotor. The use of this composition made it possible to avoid blocking the rotor with simultaneous cooling of the cutting tools, "comments Anton Rokotiansky, technical specialist at BASF. - According to the estimations of the engineering and technical staff of the general contractor, the MasterRoc ABR 5 composition, used for the new Baikal tunnel, increased the cutting tool by approximately 25%. In addition, its use has provided effective dust suppression, which has made it possible to improve the working conditions of the TPK operator. "

Also, BASF solutions were used in stopping medium water inflows and small water filtration through tunnel lining blocks. For these purposes, MasterRoc MP 355 Thix polyurethane resin and MasterRoc MP 304 acrylate injection system were used. The tunnel tunneling works began in 2014 from the western portal to the east parallel to the old Baikal tunnel. The total length of the building is 6682 m, the diameter is 10 m. The first trains on it will go in 2019. The tunnel will increase the carrying capacity of the Baikal-Amur Mainline by 2.5 times. According to the head of state, the project will be the fastest-paying in the development of the entire Russian transport system.
