Abstract
In order to solve the bearing problem of poor foundation, thorn piles were proposed, however, the construction of precast thorn piles is still in the blank stage in the project. In this paper, the research on the engineering realization method of precast thorn piles is carried out. Inspired by telescopic rod, the method of prefabricated pile body and pneumatic pressure pushing into thorns is adopted, which effectively solves the key technological problems of pile thorn stabilization at the piling formation stage, the overall air tightness of piles, and pile thorn rebound, and finally a sleeve-type thorn piles is designed. The research results can provide a theoretical basis for the research and development of precast thorn pile molding equipment, and lay the foundation for the subsequent engineering application of precast thorn piles.
