MANUFACTURING METHOD OF SEGMENT

摘要

PROBLEM TO BE SOLVED: To shorten the manufacturing time up to a surface finishing process without causing a water route or cracking in a manufacturing method of a segment. SOLUTION: Highly flowable concrete is cast in a form and subsequently heated internally to be brought to a self-supporting and surface finishable state. A lid form is detached to perform the surface finish and steam curing before a concrete segment is demolded. COPYRIGHT: (C)2007,JPO&INPIT
