METHOD AND STRUCTURE FOR BRIDGE PIER MOULD CONSTRUCTION USING CONCRETE WATER BARRIER

摘要

A bridge pier construction method using a reinforced concrete cutoff barrier and a cutoff barrier structure for a bridge pier are provided to improve waterproof efficiency by installing a water swelling stopper between a cutoff barrier and a bridge pier shoe. A cutoff barrier structure(200) for a bridge pier comprises a concrete material(230) integrally connected to an inner peripheral surface of a bridge pier shoe(10) with an anchor member, corresponded to an inner peripheral surface of a void; upper and lower reinforcing bars(210) separately installed at upper and lower parts inside the concrete material. A plurality of upper and lower reinforcing bars are crossly installed in a lattice shape, and the upper reinforcing bars are installed more densely than the lower reinforcing bars. More than one block member with a through-hole communicating the upper part and the lower part are mounted in the concrete material. The water swelling stopper is mounted between a rim of outer peripheral surface of a cutoff barrier and the inner peripheral surface the bridge pier shoe.
