TEST DEVICE FOR ROCK PERMEABILITY
PROBLEM TO BE SOLVED: To provide a test device for rock permeability that enables water injection pressure to be adjusted in a short time lag, thereby enabling highly accurate data to be easily collected.SOLUTION: The test device for rock permeability is provided, comprising a packer 2 disposed in a test hole H drilled into a rock and partitioning a test section A inside the test hole, a rod 1 penetrating through the packer 2 and pressure-feeding test water into the test hole H, water injection pipe 6 inserted into the rod 1 and causing the test water to flow into the rod, a pump 7 for feeding the test water to the water injection pipe 6, and pressure detection means 5 for detecting pressure in the test section. Furthermore, an on/off valve 17 is provided at a tip of the water injection pipe 6, for closing the water injection pipe when pressure is below a preset pressure value and opening the water injection pipe when the pressure exceeds the preset pressure value for supplying the test water into the rod 1.SELECTED DRAWING: Figure 1
【課題】注水圧力を短いタイムラグで調整することができ、よって容易に精度の高いデータを採取することが可能になる岩盤の透水試験装置を提供する。【解決手段】岩盤に穿設された試験孔Ｈ内に配置されて試験孔内の試験区間Ａを区切るパッカー２と、パッカー２を貫通して試験孔Ｈ内に試験水を加圧供給するロッド１と、ロッド１内に挿入されてロッド内に試験水を流入させる注水管６と、注水管６に試験水を供給するポンプ７と、試験区間の圧力を検出する圧力検出手段５とを備え、かつ注水管６の先端部に、予め設定された圧力以下においては注水管を閉じるとともに、上記圧力を超えた際に開いて試験水をロッド１内に流入させる開閉バルブ１７を設けた。【選択図】図１
