METHOD FOR PLACING DRAIN MATERIAL AND DRAIN MATERIAL PLACING DEVICE THEREFOR
To provide a method for placing drain material and a drain material placing device for use in the method, which can be efficiently and safely used in placing mainly short drain materials.SOLUTION: A suspension fixture 13 is provided at an upper end of drain material 1 of a predetermined length L. A wire 9 inserted into a mandrel 8 and pulled out from the lower end of the mandrel 8 is connected to the suspension fixture 13. After the drain material 1 is pulled into the mandrel 8 from below by the wire 9, an anchor member is secured to the lower end of the drain material 1. The mandrel 8 is penetrated into the ground A while the wire 9 is unrolled, and then the mandrel 8 is pulled out of the ground A to bury the drain material 1.SELECTED DRAWING: Figure 1
【課題】主に短尺のドレーン材の打設において効率よく施工でき、且つ、安全に作業を行うことができるドレーン材の打設方法及びそれに使用するドレーン材打設装置の提供。【解決手段】所定長さＬのドレーン材１の上端部に吊り具１３を設け、マンドレル８内に挿通され、先端がマンドレル８の下端より引き出されたワイヤ９を吊り具１３に連結し、ワイヤ９でマンドレル８内にドレーン材１を下方から引き入れた後、ドレーン材１の下端にアンカー部材を係止させ、ワイヤ９を繰り出しつつマンドレル８を地盤Ａに貫入し、しかる後、マンドレル８を地盤Ａより引き抜くことによってドレーン材１を埋設する。【選択図】図１
