HOLE INNER CARGO LOADING TEST DEVICE
PROBLEM TO BE SOLVED: To provide a hole inner cargo loading test device capable of executing a hole inner cargo loading test with high accuracy, by stably holding sonde internal pressure by a lightweight and simple device not corresponding to a high pressure gas manufacturing facility.SOLUTION: A hole inner cargo loading test device comprises a sonde arranged in a test hole formed in the ground, pressurized liquid supply means for supplying a pressurized liquid in this sonde, pressure detection means for detecting pressure in the sonde and measurement means for detecting displacement of an inner wall of the test hole by the sonde, and the pressurized liquid supply means comprises a double-acting pump, a tank for supplying liquid to respective cylinder chambers in front and in rear of a piston of this double-acting pump and a discharge side pipe for introducing the pressurized liquid from the respective cylinder chambers of the double-acting pump into the sonde, and the measurement means is a water level sensor installed in the tank and detecting a liquid level of the liquid.
【課題】高圧ガス製造設備に該当しない軽量かつ簡易な装置によって、しかもゾンデ内圧を安定的に保持して高い精度で孔内載荷試験を行うことができる孔内載荷試験装置を提供する。【解決手段】地盤に形成された試験孔内に配置されるゾンデと、このゾンデ内に加圧した液体を供給する加圧液供給手段と、上記ゾンデ内の圧力を検出する圧力検出手段と、上記ゾンデによる上記試験孔の内壁の変位を検出する測定手段とを備えた孔内載荷試験装置において、上記加圧液供給手段は、複動ポンプと、この複動ポンプのピストンの前後の各シリンダ室に液体を供給するタンクと、上記複動ポンプの上記各シリンダ室からの加圧液体を上記ゾンデ内に導入する吐出側配管とを備えてなり、かつ上記測定手段は、上記タンクに設置されて上記液体の液面を検出する水位センサである。【選択図】図１
