APPARATUS AND METHOD FOR ESTIMATING PERPENDICULARITY OF LARGE STEEL PILE

摘要

PURPOSE: A device using the measurement of a head difference between a pair of head measuring members for measuring the perpendicularity of a steel pipe pile with a large diameter and a method using the same for measuring the perpendicularity of the steel pipe pile with a large diameter are provided to measure the perpendicularity of the steel pipe pile easily. CONSTITUTION: A device for measuring the perpendicularity of a steel pipe pile (1) comprises a pair of head measuring members (10), a measuring solution connection-supply pipe, a level measuring solution, and a pair of joining jig members (30). The head measuring members are arranged respectively and perpendicularly in the uppermost part of the steel pipe pile. The measuring solution connection-supply pipe connects the pair of head measuring members so that the pair of head measuring members is mutually communicated. The level measuring solution is contained in the measuring solution connection-supply pipe and the pair of head measuring members. The joining jig members are joined to the uppermost part of the steel pipe pile to be detachable so that the head measuring members are perpendicularly installed. A bearing is arranged on the inner surface of a material which is directly in contact with the uppermost part of the steel pipe pile so that the material is easily moved along the uppermost circumference of the steel pipe pile by rolling the bearing.
