Abstract

A method provides first tunnel partial exca¬va¬tion so that it would be consist of excavated part 14 and II tunnel unexcavated part 12; perforation the¬rein horizontal direction between parallel tunnels I and II; standoffs insertion into horizontal passing apertures so that ends therebe moved away from II tunnel excavated surface 11; pouring cement grout; II tunnel excavation for standoffs 20 ends denu¬da¬tion, pouring strengthening concrete on II tunnel; forming plate structure 40 on denuded standoffs ends; fastening baseplate with a washer; unexcava¬ted part 12 excavation; pouring strengthening conc¬rete on excavated tunnel surface for creating basep¬late on standoffs ends denuded at I tunnel wholy excavation; and strengthening plate with a nut.
