Summary: | The invention provides a pre-stressed concrete pipe pile end pressure grouting construction process which is used for achieving the purposes that in the pipe pile construction process, high-pressure cement grouting is conducted on a pile end, so that the bearing capacity of soil at the end is brought into full play, the bearing capacity of a pipe pile is further improved, the using amount of the pile is reduced, and the engineering cost is reduced. The process includes the steps that a grouting device is welded to the pipe pile end of a lower-section pipe pile; the lower-section pipe pile and an upper-section pipe pile are hoisted in sequence, and connecting parts of the lower-section pipe pile and the upper-section pipe pile are welded into a whole to form a main pipe pile; the upper end of the welded main pipe pile is subjected to static pressure pile sinking to a designed elevation through a static pressure pile machine; and the static pressure pile machine is moved away, and high-pressure grouting is cond |
