Sediment collecting device for lowering reinforcement cage

A sediment collecting device for lowering a reinforcement cage relates to the technical field of cast-in-place pile construction and comprises a collecting barrel with an opening in the upper end, opening and closing covers which are evenly distributed in the circumferential direction are installed at the upper end of the collecting barrel, the lower ends of the opening and closing covers are hinged to the edge of the opening of the collecting barrel, and a control mechanism is installed in the collecting barrel. The control mechanism is used for controlling all the opening and closing covers to be opened or closed synchronously. After the device is placed at the bottom of a hole, soil residues and the like falling to the bottom of the hole can be collected, efficiency is high, and safety is good. 一种钢筋笼下放沉渣收集装置，涉及灌注桩施工技术领域，包括上端开口的收集筒，在所述收集筒的上端安装有圆周均布的开合盖，所述开合盖的下端铰接在所述收集筒的开口边缘上，在所述收集筒内安装有控制机构，所述控制机构用于控制所有的所述开合盖同步打开或关闭。本新型将该装置放入孔底后，能够收集掉落到孔底的土渣等，效率高且安全性好。
