To provide a submerged sand pump capable of easily switching between suction and injection for muddy water in order to remove slime.SOLUTION: A submerged sand pump is suspended so as to be able to take out or take up, and is inserted into an underground hole where excavation is completed with muddy water as clay suspension, to suction the muddy water, pump it up to the ground and discharge it. As a power source for suctioning muddy water, a motor 170 mounted with drive shafts 170a, 170b at an upper end and a lower end respectively, is equipped so that the drive shafts 170a, 170b are arranged at both ends in a vertical direction, and to the drive shafts 170a, 170b, impellers 155, 165 for suctioning the muddy water are respectively connected.SELECTED DRAWING: Figure 6
【課題】スライム除去のための泥水の吸引と噴射の切換動作を容易に行うことができる水中サンドポンプを提供する。【解決手段】繰り出し・巻き取り可能に吊支し、泥水を安定液として掘削を完了した地中孔内に挿入して泥水を吸引し、地上に揚泥して排出する水中サンドポンプにおいて、泥水を吸引する動力源として、上端及び下端にそれぞれ駆動軸１７０ａ，１７０ｂを装備したモータ１７０を、前記駆動軸１７０ａ，１７０ｂを鉛直方向の両端に配置して装備し、前記駆動軸１７０ａ，１７０ｂにそれぞれ泥水を吸引するインペラ１５５，１６５を連結した構成を提供する。【選択図】図６
