Claims (1)
太さの改良新型エアパツカー１５を、注水管を継
ぎ足しながらボーリング孔におろす。 (ロ) 新型エアパツカー１５の下部には、水圧計
保護と動水圧防除用の多孔管１７を取付ける。 (ハ) 注水管１４の地上部に、水圧計のコード挿
入口と注水口をもつた注水管ヘツド９を取付ける
。 (ニ) この注水管ヘツド９を通して、水圧計１６
をボーリング孔の試験位置まで降ろす。 (ホ) 注水ポンプにより、流量計を通して注水を
始め、記録計で原位置水圧を読み取り、有効注入
圧力―注入量曲線を記録して、ルジオン値を測定
する。 以上のごとく構成されたルジオンテスト用原位
置水圧測定装置。[Scope of Claim for Utility Model Registration] (a) Lower the improved new air packer 15, which has the same inner diameter as the water injection pipe 14 and the thickness through which the water pressure gauge 16 passes, into the borehole while adding the water injection pipe. (b) At the bottom of the new air pack car 15, a perforated pipe 17 will be installed to protect the water pressure gauge and prevent dynamic water pressure. (c) Attach the water injection pipe head 9, which has a water pressure gauge cord insertion port and a water injection port, to the above-ground part of the water injection pipe 14. (d) Through this water injection pipe head 9, the water pressure gauge 16
lowered to the test position in the borehole. (E) Start injecting water through the flowmeter with the water injection pump, read the in-situ water pressure with the recorder, record the effective injection pressure-injection amount curve, and measure the Lugeon value. The in-situ water pressure measurement device for the Lugeon test is configured as described above.
