Prefabricated pipe pile for construction of ultra-long stiff composite pile and construction method
The invention discloses a prefabricated pipe pile for construction of an ultra-long stiff composite pile and a construction method. The prefabricated pipe pile comprises a plurality of pile sections which are sequentially spliced from bottom to top, and connecting devices are connected between the pile sections; and each connecting device comprises two flange plates and a protruding part, the every two flange plates are arranged at the butt joint positions of the two corresponding adjacent pile sections correspondingly, the every two pile sections are connected through the corresponding flangeplates, and each protruding part is connected with one end of one of the two adjacent pile sections and inserted into an inner ring at one end of the other pile section. The prefabricated pipe pile is easy and convenient to operate, high in construction speed, better in bearing performance and firmer in connection and fixation.
本发明公开了一种用于超长劲性复合桩施工的预制管桩及施工方法，包括由下至上依次拼接的多个桩段，各桩段之间连接有连接装置；连接装置包括两个法兰盘和凸部，两个法兰盘分别布置于两个相邻桩段的对接处，两个桩段之间通过法兰盘连接，凸部与两个相邻桩段中的一个桩段一端连接，并插入另一个桩段一端的内圈。本发明操作简单方便，施工速度快，具有更好的承载性能，连接固定更加牢固。
