APPARATUS AND A METHOD FOR SEEKING THE BLOCKAGE IN A CONCRETE SUPPLY PIPE

摘要

PURPOSE: An apparatus and a method for seeking the blockage in a concrete supply pipe are provided to quickly and accurately detect the position of blockage in a concrete supply pipe used for supplying concrete in construction of a high-rise building.;CONSTITUTION: A method for seeking the blockage in a concrete supply pipe is as follows. Inner pressures are sensed by a plurality of pressure sensors which are installed at regular intervals in the longitudinal direction in a concrete supply pipe(S120). When the internal pressure or internal pressure variation of one of the pressure sensors is lowered below the normal operation pressure range or normal operation pressure variation range after driving a concrete pump, it is determined that blockage has occurred in the position of the concrete supply pipe before the position where the pressure sensor is installed(S140).;COPYRIGHT KIPO 2011
