APPARATUS AND METHOD FOR MEASURING MOVEMENT OF BRIDGE WHEN EXTERNAL PRESTRESSING METHOD IS APPLIED TO BRIDGE BEAM

摘要

PURPOSE: An apparatus and a method for measuring a movement of a bridge are provided to precisely and stably reinforce the bridge by precisely measuring an amount of tendon members used in the bridge and a suspension of a central portion of a mold. CONSTITUTION: A settling device is mounted at both sides of a bridge mold through a bracket(2). A strand(3) is provided between the settling devices so as to prestress the bridge mold. A prestressing force measuring device(4) is mounted adjacent to the settling device. A measuring device(5) is mounted on the center of the bridge mold so as to measure the amount of tendon members. A converting section(6) is provided to convert electric signals generated from the prestressing force measuring device(4) and the measuring device(5) into numerical signals. A control section(7) receives the numerical signals so as to determine a bridge state.
