PENETRATION TESTING DEVICE AND PENETRATION TESTING METHOD
PROBLEM TO BE SOLVED: To provide a penetration testing device and a penetration testing method in order to efficiently implement a penetration test in a hole.SOLUTION: A penetration testing device D1 has a tester D11 and a hammering support device D12. The tester D11 has a sampler 40 fixed to an anvil through a rod at a lower tip and has an external cylinder 10, which is installed at perforated bottom of a cast-in-place pile, and a hammer 20, which is slidably installed in the external cylinder 10. In a penetration testing, the tester D11 is installed at the perforated bottom and the hammer 20 is lifted and dropped in the external cylinder 10 to evaluate penetration amount of the sampler 40 in the perforated bottom.SELECTED DRAWING: Figure 1
【課題】孔内において効率的に貫入試験を実施するための貫入試験装置及び貫入試験方法を提供する。【解決手段】貫入試験装置Ｄ１は、試験器Ｄ１１と打撃支援装置Ｄ１２とを含んで構成される。試験器Ｄ１１は、ロッドを介してアンビルに固定されたサンプラー４０を下方先端に備え、場所打ち杭の孔底に設置する外筒１０と、外筒１０内で滑動可能に設けられたハンマー２０とを備える。貫入試験時には、試験器Ｄ１１を、孔底に設置し、外筒１０内でハンマー２０を揚重して落下させて、孔底におけるサンプラー４０の貫入量を評価する。【選択図】図１
