The invention provides a cast-in-place pile positioning device. The cast-in-place pile positioning device comprises a reinforcement cage, a string barrel, a feeding mechanism and pile holes. The positioning device is characterized by further comprising a fixing mechanism and a limiting mechanism, the reinforcement cage comprises reinforcing ring ribs, the fixing mechanism comprises multiple groupsof cantilever rods mounted on the pile holes, the cantilever rods are square rods, and a sliding rail is arranged on one side of the cantilever rods; the limiting mechanism comprises limiting rods and hinged rods, each limiting rod is in an L shape, the top of each limiting rod is slidably connected with the sliding rail, and the bottom of each limiting rod is fixedly connected with a limiting unit; and the middle of each hinged rod is hinged to the middle of the corresponding limiting rod, each reinforcing ring rib is suitable for being installed on the inner side of the corresponding limiting unit, and the hinged rod and the limiting units jointly limit the up-down displacement of the reinforcement cage. The invention aims to overcome the floating problem of the reinforcement cage in the pouring concrete process of cast-in-place piles, realizing of accurate positioning of the concrete string barrel is facilitated, the accurate mounting position of the reinforcement cage is guaranteed, the reinforcement cage is prevented from floating in the concrete pouring process, and the pile-forming quality of the cast-in-place piles is improved.
本发明为一种灌注桩定位装置，包括钢筋笼、串筒、进料机构和桩孔，其特征在于：还包括固定机构和限位机构，所述钢筋笼包括加强环筋；所述固定机构包括安装于桩孔上的挑杆，所述挑杆为多组方杆且一侧设有滑轨；所述限位机构包括限位杆和铰接杆，所述限位杆为“L”形，所述限位杆的顶部与滑轨滑动连接，所述限位杆的底部固定连接有限制单元，所述铰接杆的中部与限位杆的中部铰接，所述加强环筋适于安装在限制单元的内侧，所述铰接杆和限制单元共同限制钢筋笼的上下位移；本发明目的在于克服灌注桩浇筑混凝土过程中钢筋笼上浮问题，有助于实现混凝土串筒精准就位，保障钢筋笼安装位置准确，防止混凝土浇筑过程中钢筋笼上浮，提高灌注桩成桩质量。
