摘要： PROBLEM TO BE SOLVED: To simplify the reinforcing work or secondary lining to shorten the term of works by preliminarily providing a cut in the opening forming part of a shield tunnel, and using a steel frame segment not filled with concrete. SOLUTION: The opening part to a shaft B of a shield tunnel A formed by a steel frame concrete segment 11 is preliminarily cut in an opening forming area, and a steel frame segment 10 not filled with concrete is used. The lower end circumference of the retaining wall 22 of the shaft B is subjected to soil improvement 23, and a reinforcing timbering is set within the shield tunnel A. The opening forming area of the steel frame segment 10 is removed to form an opening, and a reinforcing horizontal beam is welded to the whole circumference of the opening. The reinforcing timbering is removed finally, concrete is filled in the steel frame of the steel frame segment 10 left as a part of the shield tunnel A to complete the opening. Since the reinforcing work or secondary lining work can be simplified, the period of works can be shortened, and the cost can be reduced.

摘要： PROBLEM TO BE SOLVED: To simplify a joint structure in circumferential direction of a tunnel and increase a connection strength against a displacement force in inner and outer directions of the tunnel. SOLUTION: A steel shell segment is so formed that the connection of steel shell segments 1 opposed to each other in tunnel axial direction (between segment rings) is performed by an engagement of a male side engaging member 35 with a female side engaging member 36 installed on a web 13 of a steel shell side frame 5 through a cut-off packing (sealant). The joint member of the steel shell segment 1 in tunnel circumferential direction (segment) is formed of a joint part platy steel material 20 surface-contactable between the members opposed to each other. The cut-off packing is installed in a packing stamping groove 24 formed in the joint part platy steel material 20, and both joint part platy steel materials 20 are connected water-tight to each other through the cut-off packing. Then, an engagement recessed part 46 used commonly with an assembly positioning guide installed on the joint part platy steel material 20 is engaged with an engagement projected part 47.

摘要： PROBLEM TO BE SOLVED: To connect steel shell segments in the circumferential direction of a tunnel in a simple structure and in a small moving range by putting the end faces of the segments in face contact with each other. SOLUTION: A steel shell segment has end face plates 20 fixed to both ends of a pair of circular steel shell side face plates arranged in parallel to form a steel shell segment body. A reinforced concrete 14 is filled in a space in the steel shell segment body. Engagement protrusions 30 and engagement holes 22 are provided at four corners of the steel shell segment in such a manner that they are in mutually reverse arrangement at both ends of the steel shell segment and they have respective axial lines in the axial direction of the steel shell segment. The engagement protrusions 30 are welded to the steel shell side face plates and the engagement holes 22 are opened in connection plates welded to the steel shell side face plates so as to be protruded from the end faces of the end face plates 20. The end face plates 20 of the steel shell segment to be jointed together in the circumferential direction of a tunnel are shifted to one axial direction of the tunnel to be put in face contact with each other and moved to the other axial direction of the tunnel so that the engagement protrusions 30 can be fitted into the engagement holes 22.

摘要： PROBLEM TO BE SOLVED: To provide a structure such that a simple stopper structure prevents disengagement of an engaging part where segments adjoining to each other along the circumferential direction of a tunnel are connected together. SOLUTION: This segment connecting structure is so designed that a connecting arm provided on one of segments that adjoin to each other along the circumferential direction of a tunnel is inserted and locked in an engaging hole which is bored in a locking member provided on the other segment and which passes along the direction of the tunnel axis. In this case, a male locking projection 33 is attached to either the connecting arm 19 or locking member 20a, and the other is provided with a female stopper 34 which, as the engaging hole 20 is fitted over the connecting arm 19, allows the male locking projection 33 to push its engaging part and pass through it, so that the engaging part is engaged with the male locking projection 33 by its returning movement to prevent the male locking projection 33 from coming out.

摘要： PROBLEM TO BE SOLVED: To facilitate the operation for closing a cut-off valve in the vicinity of a concrete placing inlet after the completion of concrete-place into a form. SOLUTION: A concrete conveying pipe line device 20 is applied to a concrete placing method for conveying the concrete into a form from the side of the form. In that case, a concrete conveying pipe 26 is connected to a concrete placing inlet pipe. a pipe line cut-off device 46 is provided to the concrete conveying pipe 26, and a pressure adjustment 27 used for pipe line air vent is provided to an upstream section 26b thereof. After the completion of concrete place, a cover 57 of the pressure adjustment 27 used for pipe-line air vent is opened, and the cut-off valve 45 is immediately closed. Then, since the upstream side of the cut-off valve 45 is evacuated, the cut-off valve 45 can be closed in a state to act no high on the cut-off valve 45, and the cut-off valve 45 can be closed with light force.

摘要： PURPOSE:To control the concn. of the plating solution for a long time and to enable stable plating by removing the increment of the hydrogen ion concn. from the plating bath by use of a diffusion dialysis tank. CONSTITUTION:In the process of plating, the hydrogen ion concn. in the plating tank B increases. When the initial concn. of sulfuric acid in the cathode room (b) of the electrolysis tank A is set low, the hydrogen ion concn. in the dialysis tank C differs between two rooms separated by an anion-exchange membrane. This causes diffusion of sulfuric acid to the room of lower concn. as shown by an arrow D in the figure. Thereby, the desulferized soln. returns to the plating tank B as shown by an arrow E, while the soln. into which sulfuric acid diffuses returns to the cathode room (b) of the electrolysis tank A as shown by an arrow F. Since the anion-exchange membrane 4 is used in the dialysis tank C in this process, Ni, Zn or Co ions hardly move to the room of lower concn.
