The construction management mannered null

摘要

PROBLEM TO BE SOLVED: To provide a construction management method of a steel pile by a vibro-hammer capable of making the filling management of a flowable hardener by only making the operation of pile driving without being required for difficult flow adjustment of the flowable hardener.;SOLUTION: When the depth of the steel pile 1 is measured by a depth measuring instrument to transmit its result to a program to carry out foot protection construction of a pile front end section 10, time required for excavation by water injection and filling of the flowable hardener 11 is calculated by flow per unit time and estimated filling, the time is allotted to a vertical process and a fixed injection time so that it becomes homogeneous in each depth of foot protection, its result is input in the program operating on PC to make a graphic indication as a planned construction process when the coordinates taking the construction time to the axis of an abscissa and the depth to the axis of an ordinate is filled with the flowable hardener, and an operator is so operated that the graphic indication of the actual measured depth of the pile of the indication on the display by visibility can coincide with the graphic indication of the planned construction process to make it possible to fill the flowable hardener as a planned value.;COPYRIGHT: (C)2006,JPO&NCIPI
