drilling downとは 意味・読み方・使い方

A down-the-hole hammer drilling machine 1 is provided with a drilling speed detecting means 23; the bedrock is drilled by means of the drilling machine 1; and it is determined that the bedrock and the like are cracked on a depth site which is changed to the side of an increase in drilling speed detected by means 23 in a drilling step.例文帳に追加

ダウンザホールハンマー削孔機１に対し削孔速度検知手段２３を設け、前記削孔機１により岩盤を削孔するとともに、この削孔過程で前記削孔速度検知手段２３により検知された削孔速度が速くなる側に変化する深さ部位において前記岩盤類の割れ目があると判定する。 - 特許庁

After the completion of drilling in the enlarged diameter state, again the drilling blade 3 is pushed down by the lower end of the hollow pipe 1, the relief valve of the fluid pressure cylinder 5 is opened to reduce the diameter with the drilling blade 3 bent downward, and the drilling rod 2 is pulled out of the hollow pipe 1.例文帳に追加

拡径状態での掘削完了後、再び中空管１の下端で掘削翼３を押し下げ、流体圧シリンダ５のリリーフ弁を開放して掘削翼３を下向きに折り曲げた状態まで縮径し、掘削ロッド２を中空管１内より引き抜く。 - 特許庁
