摘要： PROBLEM TO BE SOLVED: To provide a fastener capable of securely fastening fastened members to form a correct fastening state, maintaining the correct fastening state even when a relative position of the fastened members is changed by aging, and achieving compactness.
SOLUTION: This fastener is provided with a male member 12 to be installed on one fastened member 10, a female member 13 to be installed on the other fastened member 11, a wedge member 14 fitted in between the male member 12 and the female member 13 as the male member 12 and the female member 13 are fastened to fill the gap between the male member 12 and the female member 13, and an elastic member 15 to energize the wedge member 14 to the fitted-in side. The wedge member 14 and the elastic member 15 are formed like plates, and the wedge member 14 and the elastic member 15 are disposed to be laminated between a bottom surface 20 and an inner wall surface 28a of a wider part containing hole 28 as fastening surfaces of the male member 12 and the female member 13.

摘要： PROBLEM TO BE SOLVED: To provide segments which contribute to minimization of manual fastening work and efficient connection thereof.
SOLUTION: The plurality of segments which are connected together to constitute a structure, each have connecting surfaces a to be connected to the surface of the other segment, and one of the connecting surfaces a has a male joint 1 and the other connecting surface a has a female joint 2 to be connected to the male joint 1. The male joint 1 is protruded from the connecting surface and the female joint 2 is a hole into which the male joint 1 is fitted. Then a slipout preventing device and an elastic member are interposed into a fitting portion between the male joint 1 and the female joint 2. The slipout preventing device prevents slipout of the male joint 1 from the female joint 2. The elastic member is compressed when the male joint 1 is fitted into the female joint 2.

摘要： PROBLEM TO BE SOLVED: To provide a method of preventing the collapse of a working face in slurry shielding, which method accompanies a low risk of the collapse of a working face caused by slurry separation and power failure to keep the working face stable during a long period of suspension of shield propulsion. SOLUTION: In slurry shielding, slurry is supplied into a chamber 5 in front of a bulkhead disposed in a shield machine 1 to prevent the collapse of a working face 10 while drilling the working face 10 to propel the shield machine 1. When the propulsion of the shield machine 1 is suspended for a long period, slurry in the chamber 5 is replaced with gelled slurry prepared by mixing a gelling agent into slurry to prevent the collapse of the working face 10.
