DEVICE AND METHOD FOR DISPOSAL OF SLIME IN CAST-IN-PLACE PILE CONSTRUCTION
To make it possible to suck muddy water in an area with a small amount of a solid matter such as sand gravel and to jet muddy water into an underground hole.SOLUTION: In a device for disposal of slime in cast-in-place pile construction, an underwater sand pump 100 is equipped with a suction pipe 150 for sludge pumping that supplies muddy water for a sludge pumping pipe 40 for pumping sludge up on the ground, a suction pipe 160 for injection that supplies muddy water for a mud supply pipe 50 for jetting sludge into an underground hole, a jet pipe 55 connected to the tip of the mud supply pipe 50, and an on-off valve 77 of the mud supply pipe 50. In the device, the suction pipe 150 for sludge pumping is installed below the underwater sand pump 100 and the suction pipe 160 for injection is installed at a certain distance apart from the suction pipe 150 for sludge pumping in the vertical direction, and by opening the on-off valve 77 muddy water sucked from the suction pipe 160 for injection can be jetted into an underground hole from the jet pipe 55 through the mud supply pipe 50.SELECTED DRAWING: Figure 1
【課題】砂礫等の固形物を含むことの少ない領域の泥水を吸引して地中孔内に噴射する。【解決手段】水中サンドポンプ１００に、泥水を地上に揚泥する揚泥管４０に供給する揚泥用吸引管１５０と、泥水を地中孔内に噴射する給泥管５０に供給する噴射用吸引管１６０と、給泥管５０の先端に連結した噴射管５５と、給泥管５０の開閉バルブ７７を設け、揚泥用吸引管１５０を水中サンドポンプ１００の下部に、噴射用吸引管１６０を揚泥用吸引管１５０から鉛直方向に一定距離離間させて設置し、開閉バルブ７７を開くことによって、噴射用吸引管１６０から吸引した泥水を給泥管５０を介して噴射管５５から地中孔内に噴射可能とした場所打ち杭工法におけるスライム処理装置を提供する。【選択図】図１
