Summary:The invention discloses a construction method and structure for a prefabricated tubular pile to penetrate through a karst cave. Force of the prefabricated tubular pile (7) is directly transferred to aforce holding layer (2) at the bottom of the karst cave through a steel pipe (5) penetrating through the karst cave (1). The construction problems that in the process of constructing the prefabricated tubular pile in the karst cave, the prefabricated tubular pile is likely to sink and incline and the bearing capacity at the bottom of the pile does not meet design requirements are effectively solved, the effect of reinforcing a soil body of the karst cave can be effectively achieved, and the bearing capacity requirement of the bottom of the prefabricated tubular pile can be guaranteed. Meanwhile, the construction technology can be used for reinforcing the force holding layer of the pile bottom of the prefabricated tubular pile in the karst cave in a targeted manner, so that the construction period is shortened, th
