Precast concrete pipe pile
The prefabricated concrete pipe pile comprises a shell, two annular steel blocks are symmetrically installed in an inner cavity of the shell up and down, a plurality of auxiliary steel bars are evenly distributed and installed between the two annular steel blocks, and bundle penetrating holes matched with steel strands in the prefabricated concrete pipe pile for use penetrate through the top face provided with the shell to the bottom face. Clamping piece grooves are formed between the shell and the annular steel block and located in the upper end and the lower end of the bundle penetrating hole, conical clamping pieces are installed in the clamping piece grooves, and the conical clamping pieces at the upper end and the lower end are arranged in a staggered mode, that is, in the same bundle penetrating hole, the conical clamping piece is installed in the clamping piece groove at the upper end, or the conical clamping piece is installed in the clamping piece groove at the lower end. The precast concrete pipe pile is simple and reasonable in structure, novel in design, easy to operate, high in practicability and convenient to widely popularize and use.
本发明提出了一种预制混凝土管桩，包括外壳，外壳的内腔中上下对称安装有两个环形钢块，两个环形钢块之间均布安装有若干个辅助钢筋，安装有外壳的顶面贯穿至底面均布开设有配合预制混凝土管桩内钢绞线使用的穿束孔，外壳与环形钢块之间开设有夹片槽，夹片槽位于穿束孔的上下两端，夹片槽内安装有锥形夹片，上下两端的锥形夹片呈交错设置，即同一穿束孔内或是上端夹片槽中安装有锥形夹片，或是下端夹片槽中安装有锥形夹片。该种一种预制混凝土管桩，结构简单合理，设计新颖，操作简单，具有较高的实用性，便于广泛推广使用。
