Description
【００１４】
スパイラル帯鋼はケーシングロッド内の長手方向のいずれの部位に設けてもよいが、ケーシングロッドの後部に設けるとスパイラル帯板によって土砂類の取込み量を制限しても多量の土砂類がケーシングロッド内部に溜まり、固くなってしまうと、ケーシングロッドを逆回転させても上手く取込むことができないおそれがあるので、スパイラル帯板の先端を少なくともケーシングロッドの先端側に位置させるのが好ましい。スパイラル帯板の材質は特に限定されず、例えば帯鋼を使用することができる。[0014]
The spiral strip steel may be provided at any position in the longitudinal direction in the casing rod, but if it is provided at the rear of the casing rod, a large amount of earth and sand will be inside the casing rod even if the amount of sediment taken in is limited by the spiral strip It is preferable to position the tip of the spiral strip at least on the tip side of the casing rod, since it may not be able to be taken in well even if the casing rod is reversely rotated if it accumulates and becomes hard. The material of the spiral band is not particularly limited, and, for example, band steel can be used.
