CONSTRUCTION METHOD OF HOLLOW TYPE PIER STRUCTURE WITH CONTROLING CURING HEAT OF MASS CONCRETE

摘要

A method for constructing pier structure with hydration heat control is provided to prevent excessive hydration heat from generating during the construction of the pier structure by burying a steel pipe in the structure. A method for constructing pier structure with hydration heat control comprises a step of vertically installing a hollow steel pipe in the pier structure. An iron bar(20) surrounds the steel pipe to assemble a mold. Concrete(30) surrounds the steel pipe. Cooling air is introduced into the steel pipe so that the hydration heat generated from the concrete(30) is reduced. The steel pipe includes a core steel pipe(10A) which is placed at the center of the pier structure, and a peripheral steel pipe(10B) which is placed around the core steel pipe(10A). The core steel pipe(10A) is connected to the peripheral steel pipe(10B) through a connection pipe(11).
