Document Type and Number:
WIPO Patent Application WO/2017/130557
Kind Code:
A1
Abstract:
The purpose of the invention is to provide a groundwater detection method that can accurately detect groundwater while performing geological survey (boring work), and a boring device used for same. Provided is a groundwater detection method wherein: the ground (G) is excavated and a core (C) is accommodated in a core tube (10) by rotating or translating a rod (20) while a fluid (F) is discharged from the core tube (10) connected to the rod (20), and the properties of the fluid (F) in an excavated hole or the fluid (F) being discharged from the excavated hole are measured with a measuring unit (60); and groundwater (GW) is detected from the properties of the fluid (F) measured by the measuring unit (60).
