DEVICE FOR MEASURING DISPLACEMENT OF A PIER IN CASE OF SETTLEMENT OF A STEEL PIPE PILE FROM CONTINUOUS UPPER MOVING LOAD FOR DETECTING SAFETY OF A BRIDGE

摘要

PURPOSE: A displacement measuring device of a pier for detecting safety of a bridge is provided to improve stability of the bridge, and to prevent accidents by promptly measuring displacement such as inclination of the pier from subsidence of a pile. CONSTITUTION: A pier displacement measuring device(900) is installed in an upper center of an abutment(100) before constructing a pier(200) of a bridge to measure displacement of the pier after pouring concrete. A lower measuring device post is fixed to the abutment by assembling anchor holes of a circular plate with fixing anchors and composed of a bolt part. Cross measuring bars are composed of vertical penetration bodies, displacement measuring bars fixed perpendicularly to the vertical penetration bodies, and a nut part formed in an end of the displacement measuring bar. An upper measuring device post is combined with the lower measuring device post and the cross measuring bars. A displacement measuring unit is combined with the displacement measuring bars to prevent freezing by injecting anti-freezing solution. An upper post cover is combined with an upper bolt part of the upper measuring device post.
