摘要： PROBLEM TO BE SOLVED: To prevent the thickening of a segment constituting a lining body. SOLUTION: Grooves 1g are opened to the tunnel internal side face 1c of a lining body 1 to a joint section 1f between a plurality of mutually adjacent segments 1a constituting the lining body 1 and formed in a shape extended along the joint section 1f, the tunnel internal opening of the grooves 1g is covered with a thin waterproof cap 6 while the waterproof cap 6 is fixed onto the tunnel internal side face 1c of the lining body 1, a drainage canal 9 is surrounded and formed by the waterproof cap 6 and the grooves 1g, and the leakage of water into the tunnel through the joint section 1f from a ground is guided to the invert section of the lining body 1 by the drainage canal 9. When the lining body 1 is used as a primary lining body and a second lining body 11 is installed, the drainage canal 9 prevents infiltration between the joint surfaces of the primary lining body 1 and the second lining body 11 of the leakage of water. The secondary lining body 11 can be thinned by the thin type of the waterproof cap 6.

摘要： PROBLEM TO BE SOLVED: To provide an effect for lowering the force of sectional area when an earthquake is generated by forming a washer for joint, which is to be provided between rings of a segment inside of a block as an object of base isolation, of an elastic body, and arranging a base isolation layer in the periphery of a cover body. SOLUTION: A shield tunnel 2 is constructed over a soft ground 1S and a hard ground 1H, and when an earthquake is generated, ground condition is suddenly changed in a boundary of stratum and large distortion of ground are concentrated to the boundary of stratum. But, at the time of transmitting the distortion of ground to the tunnel 2, the distortion is firstly absorbed for lowering by a base isolation layer 15 in the periphery of a cover body 3. Furthermore, the distortion transmitted to the cover body 3 is absorbed by the extension and contraction of an elastic washer 11. Consequently, each function of both the elastic washer 11 and base isolation layer 15 is effectively exhibited by using the elastic washer 11 and the base isolation layer 15 together. The force of sectional area at the time of earthquake to be applied to the tunnel is lowered by the multiplier work thereof. With this structure, a block as an object of base isolation is shortened, and the isolation to water-leak is prevented so as to maintain the function as a tunnel.
