Problems solved by technology
[0003] However, when splicing two prestressed concrete pipe piles together, the prestressed concrete pipe piles are contaminated with a large amount of soil during transportation, and the soil blocks the connecting pipes, making it inconvenient to connect the steel bars inside the two prestressed concrete pipe piles together.

The invention relates to the field of concrete tubular piles and specifically relates to a pre-stressed steel tube concrete tubular pile which comprises a drill bit, main bodies, connection mechanisms, lap joint mechanisms, fixed mechanisms, first sealing mechanisms, second sealing mechanisms and discharging grooves, wherein the connection mechanisms are arranged at the two ends of the main bodies, the lap joint mechanisms are arranged in the connection mechanisms, and the second sealing mechanisms are clamped in the lap joint mechanisms; in a process of conveying the main bodies, the insidesof the lap joint mechanisms are sealed by the second sealing mechanisms, soil is prevented from entering the insides of the lap joint mechanisms, the first sealing mechanisms are in sliding connectionwith the second sealing mechanisms, the fixed mechanisms are arranged in the connection mechanisms, the fixed mechanisms abut against the first sealing mechanisms, the first sealing mechanisms can slide in the connection mechanisms when the fixed mechanisms and the first sealing mechanisms are separated, the second sealing mechanisms are driven to slide on the top surfaces of the first sealing mechanisms, the second sealing mechanisms can slide out of the lap joint mechanisms, the lap joint mechanisms can be opened, and the two main bodies can be conveniently assembled by people.
Description
technical field [0001] The invention relates to the field of concrete pipe piles, in particular to a prestressed steel pipe concrete pipe pile. Background technique [0002] The prestressed concrete pipe pile is a tubular slender member driven into the soil with a cross-sectional size much smaller than its length. The upper part of the pipe pile is connected with the cap (beam) to form a pile foundation. Its basic structure is a prestressed concrete structure, which can be divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles. It has the characteristics of large bearing capacity, good stability and small settlement value, and can adopt mechanized construction, which greatly improves the construction progress. [0003] However, when two prestressed concrete pipe piles are spliced together, the prestressed concrete pipe piles are contaminated with a large amount of soil during transportation, and the soil blocks the connecting pipe, whic...
