Core view, core evaluation method and core correction method

摘要

The present invention provides a core display diagram and a core evaluation method capable of appropriately evaluating the nature of the core, and the core or the core collected so as to reflect the section of the ground on which the collection was performed Provides a method of modifying a core that modifies the display of that core. The core diagram shows the opening (47) of the coring device (40) while excavating the ground (G) by rotating and moving the coring device (40) connected to the rod (32) and the rod (32) The core figure (10) displaying the core (C) collected by the boring device (30) which collects the core (C) into the internal space (48) of the core collecting device (40) and measures the physical quantity, and the physical quantity And a graph (20) to be displayed. In the core diagram (10), the longitudinal direction of the displayed core (C) is parallel to the vertical direction or the lateral direction. The graph (20) has time as one of the horizontal axis (22) and the vertical axis (24), and the physical quantity as the other of the horizontal axis (22) and the vertical axis (24). Physical quantities include the displacement or velocity of the moving rod (40) and the displacement or velocity of the core (C) entering the interior space (48) of the coring apparatus (40). In the core diagram (10) and the graph (20), the longitudinal direction of the core (C) displayed in the core diagram (10) and the horizontal axis (22) or the vertical axis (24) indicating the time in the graph (20) Parallel to each other, start time (26) and end time (28) of core collection in graph (20) are start point (12) and end point (14) of section in which core collection is performed in core diagram (10) The scale of the longitudinal scale or the time of the graph (20) of the core (C) in the core diagram (10) is adjusted to correspond to the scale of the horizontal axis (22) or the vertical axis (24) It is displayed side by side or stacked.
