LINING ELEMENT AND LINING STRUCTURE USING THE SAME

PROBLEM TO BE SOLVED: To provide a lining element and a lining structure using it capable of constructing a thin wall in the lining structural body using the lining element. SOLUTION: In the lining structure constructed by inserting the lining elements 1 and 2 in parallel with each other to partition an empty section in a tunnel, the lining elements 1 and 2 are constituted of body elements 10 and 20 for forming a tunnel wall and working elements 16 and 26 detachably connected to the body elements 10 and 20 and working elements 16 and 26 for carrying out work excavating the insides of the tunnel. The lining elements 1 and 2 are connected with the body elements 10 and 20, and after the insides of the working elements 16 and 26 have been excavated, the working elements 16 and 26 are detached from the body elements 10 and 20 to remove. Then, since the connected body elements 10 and 29 are only left over, the necessary and sufficient thin wall as a tunnel lining structural body can be constructed. COPYRIGHT: (C)2005,JPO&NCIPI
