ABSTRACT:
A system for automatically measuring piling results of a piling operation. The system comprises a pile numbering unit, an operational date setting unit, a reference sinking amount setting unit, an average times of hammering setting unit, a stop signal generating unit, a start signal generating unit, a pile sinking displacement measuring unit, a pile perpendicularity detecting unit, a hammering sound detecting unit, a central processing unit, a data printer, a signal display, an informing speaker, a pile perpendicularity display, and a measuring arm for mounting the pile sinking displacement measuring unit and the pile perpendicularity detecting unit. The system of this invention provides an advantage in that it carries out the piling operation without an error, and needs no piling operator for controlling the piling operation, resulting in curtailment of personnel expenditures, efficiently preventing a safety accident, and another advantage in that the results of the piling operation are stored in an electronic circuit which can not be fabricated, and printed by a printer, thereby accomplishing an automatic superintendence for the piling operation. The system of this invention can visually display the perpendicularity of the pile in order to provide an easy and exact observation of the perpendicularity of the pile.
