This paper introduces the characteristics of rotating extrusion cast-in-situ piles and puts forward construction methods suitable for western Liaoning Province. Combined with engineering cases, this paper expounds the construction conditions and techniques of rotary cast-in-place piles, strengthens the quality technical measures and the key points to control the quality of piles. The feasibility of design and construction is confirmed by the test of the integrity of the pile foundation and the test of the vertical bearing capacity of the pile, so as to provide reference for similar projects.
