A mobile terminal that constitutes a pile construction management method, a pile construction management system, and a pile construction management system.

摘要

PROBLEM TO BE SOLVED: To perform a pile construction management method and a pile construction management system capable of performing construction management of a steel pipe pile while accurately specifying a pile core position of a steel pipe pile in the vicinity of the ground without having a complicated jig. , And to provide mobile terminals that make up the pile construction management system. SOLUTION: This is a pile construction management system 500, and a target 100 fixed on a steady rest member 50 or on the ground around a steel pipe pile P, a measuring instrument 200 for measuring the position of the target 100, and a pile. It has an electronic compass 150 that measures at least the angle of the X-axis or Y-axis from the north pole that constitutes the stake, and a portable terminal 300 that the operator of the base machine 10 has. The mobile terminal 300 includes the measuring instrument 200 and the electronic compass. It includes a receiving unit 320 that receives measurement data transmitted from 150, and a calculation unit 330 that reads measurement data related to the position and angle data of the target 100 from the receiving unit 320 and calculates the pile core position of the steel pipe pile.
