Abstract

PURPOSE: To quicken the construction works by moving slip forms by a guide means along a tunnel cross section, supplying the slip forms with concrete and mortar through a concrete-mortar supply means and constructing a new lining on an existing tunnel. CONSTITUTION: Slip forms 13 are moved to the movable guide 11 sides and faced oppositely to an existing lining 29 at the lower end of the tunnel 21, and pushing rollers 15... are pushed against a timbering 22 and a space 17 is formed between the forms 13 and the lining 29. The space 17 is supplied with concrete and mortar 25 and the forms 13 are moved gradually towards a tunnel top-end section 21a while being placed along guides 11, and a new lining 26 is constructed on the existing lining 29. The slip forms 13 are shifted up to the top end section 21a by moving the pushing rollers 15... along the timbering 22 in the direction of the timbering 22 and faced oppositely to the existing lining 29, and the lining 26 is also built on other sides by the same procedure. Accordingly, repair works can be conducted continuously.
