DYNAMIC CONE PENETRATION TESTER AND GROUND RIGIDITY TEST METHOD

摘要

The present invention relates to a dynamic cone penetration tester for measuring rigidity of the ground and, more specifically, relates to a dynamic cone penetration tester which comprises: a vertical degree maintaining unit (100) including a horizontal plate (110) having a through hole (111) formed in the center thereof and a vertical support (120) coupled to the horizontal plate (110) in a vertical direction; a penetration rod (300) hit by a hammer (200) that falls freely at a predetermined height to be penetrated into the ground; an anvil (400) coupled to an upper end of the penetration rod (300) and hit by the hammer (200); a hammer guide rod (500) of which a lower end is coupled to the anvil (400) and guiding behavior of the hammer (200); and a sensor module (10).;COPYRIGHT KIPO 2020
