LINING CONCRETE CASTING AND CURING METHOD AND LINING CONCRETE CASTING AND CURING FORM

摘要

PROBLEM TO BE SOLVED: To obtain a tunnel with uniform compression strength, along with prescribed compression strength within a prescribed time.;SOLUTION: In a lining concrete casting and curing method of the present invention, lining concrete is cast and cured in a plurality of steps outside of a form when constructing a tunnel. The form is heated such that a temperature difference results between an area of the form where the concrete cast first comes in contact with and an area of the form where the concrete cast later comes in contact with, and then the lining concrete is cast and cured outside of the form. A lining concrete casting and curing form of the present invention includes a planar heat dissipating body provided separately at two or more locations inside a skin plate of the form having an upper edge form, a side form and an inverted form, along with temperature control means capable of controlling the temperature of each of the planar heat dissipating bodies separately.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
