摘要： PROBLEM TO BE SOLVED: To smoothly let the air out of an form when concrete is placed in the segment form using a steel shell segment. SOLUTION: An air vent pipe 26 is mounted to the upper part of the inside of a steel shell segment 21. One end of the air vent pipe 26 is located to a position near to the inside of an upper surface wall 24 of the steel shell segment 21 and is made to down from that position, and the other end passes under an inward flange 25. A front form 30 having a hole 32 for the front end of the lower side of the air vent pipe 26 to face thereto is mounted to the front of the steel shell segment 21, and an outside exhaust pipe is connected to the front end of the lower side of the air vent pipe 26. Concrete is placed from a concrete inlet 31. When concrete is placed. air in the form is exhausted to the outside from the air vent pipe 26 and outside exhaust pipe. Even if the steel shell segment 21 is provided with the inward flange 25 to the circumferential edge of the front opening, air is surely exhausted without being prevented from the inward flange 25, and a vertical casting system for casting concrete can be adpted by making the steel shell segment 21 as the vertical.

摘要： PROBLEM TO BE SOLVED: To ensure high productivity, low cost, reduction of labor of workers, easiness and safety of operation. SOLUTION: This manufacturing method is to arranged a a steel shell storage yard where steel shells for segments are disposed and a plurality of supporting frames for manufacturing the segment, which are formed by fixing finished segments and remove the complete segments to be transferred by a forklift and further, set up stations such as a station 57 for disassembling/cleaning front forms stored at a form storage part, an assembling station 58 for fixedly mounting the front form on the forward part of the steel shell for the segment, a station 59 for filling and curing a concrete, a finishing station 60 for cleaning the complete segment and a station 61 for disposing and storing the complete segment in orderly manner within a work site. Thus the conveyance of the complete segment and the suspension of the front form by a forklift are properly performed.

摘要： PROBLEM TO BE SOLVED: To provide a steel shell segment manufacturing method constituted so as to dispense with the surface finish work of concrete by more drastically enhancing the occurrence of air bubbles on the inner surface of concrete forming the inner surface of the steel shell segment than before. SOLUTION: The opening surface of a concrete filling recess 2 on the inner surface side of an arcuate steel shell 1 for the segment is closed by a front form 3 and, after both members are integrated by clamping metal fittings, they are inclined forward at a predetermined angle so that the upper end region 12 of the central part of the steel shell 1 is positioned at the apex of the segment to be held and the recess 2 is filled with concrete 4 from the injection port of the front form 3 while applying vibration to the steel shell 1 and the front form 3 by a high frequency vibrator 13.
