Pine pile driving construction method under mud clay foundation condition

The invention provides a pine pile piling construction method under a mud clay foundation condition. According to the method, a steel casing with a clamping function is mounted on a front body of a hydraulic breaking hammer, and a drill rod of the hydraulic breaking hammer is located in the steel casing and tightly abuts against the upper end of a pine pile; and in the pile driving process under the muddy clay foundation condition, the upper end of a pine pile is impacted through mechanical hydraulic pressure, the pine pile slowly sinks under the action of impact energy, the pine pile part sleeved with the steel casing is tightly connected with the steel casing, and it is ensured that the pine pile does not fall off from the hydraulic breaking hammer in the piling process. In the pile driving process, the pine pile is subjected to the circumferential constraint force of the steel casing, the problems of splitting and pile head damage cannot occur, construction is not affected by the external environment, cont
