にはワイヤ４を通す孔が設けられている。The sheaves 5 and 6 are attached to the upper end of the leader, and the sheaves 7 and
8 is installed on the side of the hopper 2, and the sheave 9 is installed on the top of the opening / closing lid 12 at the upper end of the casing 1, and the opening / closing lid 12 is also installed.
Has a hole through which the wire 4 passes.
ワイヤ４は検知作業中、常に緊張状態を保つようにする
が、その手段として例えばトルクモータを用いてドラム
３に一定の回転力を与えておく。The wire 4 is always kept in a tension state during the detection work, and a certain torque is applied to the drum 3 by using, for example, a torque motor as the means.
ドラム３にはその回転角度を検出するための検出器（例
えばポテンショメータの検出部）を付設し、この検出器
と電気的に接続された表示器13が被覆砂杭打設機本体の
オペレーター席に設けられている。A detector for detecting the rotation angle of the drum 3 (for example, a detector of a potentiometer) is attached, and an indicator 13 electrically connected to the detector is provided on the operator seat of the body of the coated sand pile driving machine. It is provided.

まの状態で残置されるのが打設の正常状態である。この
正常状態では、ワイヤ４は動かず、ドラム３も回転しな
いから、表示器13の指針は原点にとどまる。When the casing 1 is pulled out while supplying compressed air from the compressed air supply pipe 14 in the state shown in FIG. 1, the coated sand pile body 11
Is discharged from the lower end of the casing 1 to the ground. At this time, only the casing 1 is raised and the coated sand pile body 11 is left as it is in the normal state of driving. In this normal state, the wire 4 does not move and the drum 3 does not rotate, so that the pointer of the display 13 stays at the origin.
前述の共上がり現象が生じて被覆砂杭体11の上端部が上

ドラム３が巻き戻し方向に回転する。When the above-mentioned rising phenomenon occurs and the upper end of the coated sand pile body 11 moves upward, the wire 4 is loosened, the drum 3 is rotated in the winding direction by that amount, and the upper end of the coated sand pile body 11 is also rotated. Is pulled downward, the wire 4 is pulled, and the drum 3 is rotated in the rewinding direction by that amount.
ドラム３の回転方向と回転量は検出器で検出され、その
電気信号が表示器13に送られてその指針を動かす。The rotation direction and the rotation amount of the drum 3 are detected by the detector, and the electric signal thereof is sent to the display 13 to move the pointer.
したがって、標示器13を監視することにより被覆砂杭の
打設状況を把握することができるが、標示器13とともに
警報器を設けてこれが鳴ったときに表示器13を見るよう
にしてもよい。Therefore, it is possible to grasp the driving condition of the coated sand pile by monitoring the indicator 13, but an alarm device may be provided together with the indicator 13 and the indicator 13 may be viewed when the alarm sounds.
なお、異常を検知した場合は圧気のかけ方を調節する等
の措置を構じて是正する。If an abnormality is detected, corrective measures will be taken, such as adjusting the pressure application method.
