ULTRASONIC POROUS WALL MEASUREMENT INSTRUMENT
PROBLEM TO BE SOLVED: To provide an ultrasonic porous wall measurement instrument for efficiently performing accuracy management on a drilled hole which is provided in the ground for construction of a large depth-corresponding underground structure made of cast-in-place concrete by using an ultrasonic sensor.SOLUTION: An ultrasonic porous wall measurement instrument includes: an ultrasonic sensor 2 for measuring a horizontal distance to a hole wall; a wire 4 connected to the ultrasonic sensor 2 via a suspension tool 3; and a stabilizer 6 including insertion holes into which the wire 4 is inserted and pressing devices capable of freely appearing toward the hole wall. A support tool for supporting the stabilizer 6 is fixed to the wire 4.SELECTED DRAWING: Figure 1
【課題】大深度に対応した場所打ちコンクリート造の地中構造物を構築するべく地盤中に設けた掘削孔を、超音波センサを用いて効率よく精度管理するための、超音波孔壁測定器を提供する。【解決手段】孔壁までの水平距離を計測する超音波センサ２と、超音波センサ２に、吊り具３を介して連結されるワイヤ４と、ワイヤ４を挿通する挿通孔、および孔壁に向けて出没自在な押圧装置を有するスタビライザー６とを備え、スタビライザー６を支持する支持具が、ワイヤ４に固着されることを特徴とする。【選択図】図１
