摘要： PROBLEM TO BE SOLVED: To provide a flexible entrance joint capable of absorbing relative displacement generated between a vertical shaft and a tunnel without reducing water cutoff performance, reducing cost, and shortening a construction term. SOLUTION: This is a flexible entrance joint 10 used to connect a segment 40 of a shield tunnel with a vertical shaft wall 30A. It consists of a substantially cylindrical flexible rubber device 1 having at least inner peripheral diameter larger than an outer peripheral diameter of the segment 40 and an entrance packing 2 which shuts off water between an opening part 30B formed on the vertical shaft wall 30A due to digging by a shield machine and the segment 40. One end of the flexible rubber device 1 is joined on a mounting part 31 of the vertical shaft wall 30B and the other end thereof is joined on a peripheral fringe part 40a of the segment 40. Moreover, a longitudinal cross section of a side wall of the flexible rubber device 1 is formed like wave shapes.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus and a method, for the measurement of the leak of water, in which the component of waste in creeping water can be specified and in which the damage of a measuring electrode is small. SOLUTION: In a measuring apparatus for the leak of water, an AC power supply 6 which changes a frequency ω and which can make an AC current flow across a pair of electrodes sandwiching at least two other electrodes selected from an electrode 5,... is provided. In addition, a potential difference meter 8 which measures a potential difference between the other adjacent electrodes as a pair sandwiched between the pair of electrodes is provided. In addition, an electric-characteristic-value calculating means by which an electric characteristic value (e.g. a permittivity ε) having frequency dependence is calculated on the basis of the potential difference measured by the potential difference meter 8 is provided. In addition, a leak-of-water discrimination means by which the calculated electric characteristic value between the pair of other adjacent electrodes sandwiched between the pair of electrodes is compared with every preset discrimination value so as to discriminate whether a prescribed component is contained in the leak of water is provided.

摘要： PURPOSE:To obtain scaffolds that can be installed safely in a short time. CONSTITUTION:A scaffold lower framework 10, constructed of a front frame material 11, a rear frame material 12 and both side frame materials in a rectangular framework, and a scaffold upper framework 20, constructed likewise in a rectangular framework, are connected with upright posts 3 that are hinged at their lower ends to both of the side frame materials 13a, 13b of the scaffold lower framework 10 with the central axes of the side frame materials as their axes for rotation and hinged also at their upper ends to both of the side frame materials 23a, 23b of the scaffold upper framework 20 with the central axes of the side frame materials as their axes for rotation. A driving mechanism 4 is mounted to an appropriate position on the scaffold lower framework 10, and the driving member of the driving mechanism 4 is connected to one or more of the upright posts 3, and thereby the upright posts are made to be available for rising and falling.

摘要： PURPOSE: To prevent the change of porosity by sticking an adhesive, provided with rubber-like elasticity after adhesion, to the surface of solid pieces such as crushed stones, and throwing these solid pieces into the hole of the ground so as to construct a solid piece porous body with numerous solid pieces adhering to one another. CONSTITUTION: The compressor 26 of an air hammer type boring machine 20 is driven to apply impact force to the ground by the tip of a ground mark 23 so as to compaction-excavate and to press a steel pipe into the ground down to the specified depth. The ground mark 23 is then pulled up and taken out of the steel pipe 30. An adhesive provided with rubber-like elasticity after adhesion is stuck to the surface of solid pieces such as crushed stones, and these solid pieces are thrown in, and the steel pipe 30 is pulled out so as to construct a porous body with numerous solid pieces adhering to one another in the ground.

摘要： PURPOSE:To enable man-power saving and to make carry segments efficiently, and safely. CONSTITUTION:An upper stage side rail 31 and a lower stage side rail 32 on which a self-running segment carrying truck 40 can run from a starting vertical shaft or a starting element to a backward element of a shield excavator 10 having an erector 20 are laid on both up and down stages in the existing tunnel. The front end sides of both rails have a lifting-lowering platform with an extended rail having enough length on which the segment carrying truck can ride, and such a lifting-lowering truck 50 as the rear end of the extended rail can be switched to one or the other of the two front ends of the upper stage side rail and the lower stage side rail to connect by a position of the lifting- lowering platform is provided.

摘要： PURPOSE:To improve efficiency for delivering a segment for new erection by jointing telescopic expansion rails to the front ends of rails laid in an existing tunnel, providing a conveyor on the rails for sequentially feeding new segments along a leading end direction and installing a conveyor type segment delivery carriage on the rails. CONSTITUTION:Rails 30 are laid in an existing tunnel T, extending up to a position behind a shield machine 10. Then, telescopic expansion rails 30a with telescopic forward ends capable of expansion up to the forward ends of existing segments S1, S2, S3 and so forth advancing on the propulsion of the shield machine 10, are jointed to the front ends of the rails 30. Also, a conveyor 42 for feeding in order a plurality of new erection segments SO, SO, SO and so forth laid and placed thereon along a tunnel axial direction along a leading end direction, is installed on the rails 30 and 30 and, in addition, a conveyor type segment delivery carriage 40 capable of reciprocating on the rails 30 and 30 is installed.
