CONE PENETRATION DEVICE AND CONE PENETRATION METHOD
To provide a cone penetration device which can appropriately suppress reaction force against penetration of a cone rod with a simple configuration regardless of strength of a ground, and can efficiently investigate substance characteristics of the ground.SOLUTION: A cone penetration device 1 includes: a cylindrical foundation frame 4 which is penetrated into a water bottom ground and has a top face part 11; each injection/drainage means 5 for injecting/draining water from inside the foundation frame 4; and a penetration device 6 which is connected to the foundation frame 4, and has a cone rod 13 that is penetrated into the water bottom ground, and detects information on substance characteristics of the ground. Such a simple configuration can appropriately suppress reaction force against penetration of the cone rod 13 of the penetration device 6 with a simple configuration regardless of strength of a ground, and can efficiently investigate substance characteristics of the ground.SELECTED DRAWING: Figure 1
【課題】地盤の強弱に関係なく、簡易な構成でコーンロッドの貫入に対する反力を適切に抑えることができ、効率良く地盤の物質特性を調査することができるコーン貫入装置を提供する。【解決手段】コーン貫入装置１は、水底地盤内に貫入される、天面部１１を有する円筒状の基礎架台４と、該基礎架台４内から注排水する各注排水手段５と、基礎架台４に連結され、水底地盤内に貫入されて地盤の物質特性に係る情報を検出するコーンロッド１３を有する貫入装置６と、を備えている。そして、地盤の強弱に関係なく、簡易な構成により、貫入装置６のコーンロッド１３の貫入に対する反力を適切に抑えることができ、効率良く地盤の物質特性を調査することができる。【選択図】図１
