Background
The precast pile is generally divided into a steel pile and a concrete pile, and the common precast pile comprises a concrete solid square pile, a concrete hollow square pile and a prestressed concrete hollow tubular pile, wherein the steel pile mainly comprises a steel pipe pile and an H tubular pile. Compared with a cast-in-place pile, the precast pile has the advantages of low production cost, small reinforcement ratio, steel saving, environmental protection, small diameter, large specific surface area, large bearing capacity of single concrete, simple construction, relatively low technical difficulty, short construction period and continuous construction of engineering; the soil is positive in loose soil and unsaturated filling soil, and can play roles in encrypting and improving bearing capacity. Although there are many advantages, the disadvantages of the precast pile are also obvious. The soil squeezing effect of the precast pile is negative in saturated cohesive soil, quality accidents such as pile breakage and the like can be caused, and the precast pile cannot be used for resisting horizontal load. In addition, the precast pile enters a soil layer in a static pressure mode, when the pile end reaches a bearing stratum, the pile body is broken possibly due to the excessively increased static pressure, noise pollution is generated by adopting a hammering method, the precast pile is not suitable for urban construction, and meanwhile, soil around the pile is greatly disturbed.
