METHOD OF LINING OF TUNNEL

Japanese Patent JP2011184934

A

To provide a method of lining of a tunnel enabling preferable construction of an arch section (a top end) by securing filling performance, density and solidity of concrete.

A pair of right and left side walls 3, 4 are constructed by placing ordinary concrete 2. Fluid concrete 5 is placed to construct the arch section 6 connected to the pair of side walls 3, 4 while arranging a pressure sensor 13 on the side of a surface of a form 1 and a filling detecting sensor 12 on the side of the natural ground G. An air-bleeding hole 11 is formed in the top end 7 of the arch section 6, and blow-up ports 9, 10, (8) are arranged between the top end 7 of the arch section 6 and two ends 6a, 6b, respectively. The fluid concrete 5 is placed through the blow-up ports 9, 10, (8).
