Dry operation cast-in-situ bored pile hole bottom sediment soil sampling device
The invention discloses a dry operation cast-in-situ bored pile hole bottom sediment soil sampling device. The dry operation cast-in-situ bored pile hole bottom sediment soil sampling device comprises a soil sampling barrel, the top end of the soil sampling barrel is connected with a cross-shaped top plate, the center of the top end of the cross-shaped top plate is connected with a lifting rope, the outer wall of the tail end of the soil sampling barrel is hinged to a plurality of vertically-arranged arc-shaped steel plates, the tail ends of the arc-shaped steel plates are tip ends, the inner walls of the arc-shaped steel plates are connected with the inner wall of the soil sampling barrel through springs, the arc-shaped steel plates are folded to form a hemisphere, the center of the lower end face of the cross-shaped top plate is vertically connected with a lifting rope, the tail end of the lifting rope is connected with the center of an annular connecting piece, a plurality of horizontally-arranged transverse supporting rods are fixed to the outer ring of the annular connecting piece, and the end parts of the horizontally-arranged transverse supporting rods are inserted into transverse grooves formed in the inner sides of the arc-shaped steel plates, so that the plurality of arc-shaped steel plates are opened. The soil sampling device is reliable in structure, convenient to apply, low in cost, small in size, environmentally friendly, safe, easy to operate and rapid in soil sampling, and hole bottom sediment cleaning work can be effectively completed under complex conditions; and wide application market and development prospects are realized.
本发明公开了一种干作业钻孔灌注桩孔底沉渣取土装置，包括取土筒体，取土筒体顶端连接十字顶板，十字顶板顶端中心连接吊绳，取土筒体末端外壁铰连接若干片竖向布置的弧形钢板，弧形钢板末端为尖端，弧形钢板内壁与取土筒体内壁之间通过弹簧连接，若干片弧形钢板收拢时形成半球形，十字顶板下端面中心竖直也连接有吊绳，该吊绳的末端连接环形连接件的中心，所述环形连接件的外圈固定有若干水平布置的横撑杆，水平布置的横撑杆端部插入弧形钢板内侧开设有的横槽内以使若干片弧形钢板张开。本发明结构可靠、应用方便、成本低廉、体型较小、环保安全、操作简单、取土迅速，能有效地在复杂条件下完成孔底沉渣清理工作；具有广阔的应用市场及开拓前景。
