The prestressed pipe pile is also called as concrete precast pile, and is characterized by that it is prefabricated in the prefabricated component processing factory, and is maintained, and after the strength is reached to designed strength, it is transferred to the construction site, and driven into the soil by means of pile driver, and then the top portion of the pile is poured into the pile cap beam (plate) foundation. The prefabricated reinforced concrete pile has the advantages of simple manufacture, high strength, high rigidity, low cost, rich varieties and capability of being manufactured into various cross-sectional shapes, and is a widely adopted pile type.
However, due to the limitations of factory production, transportation, piling and other conditions, the length of a single pile is generally within 12m, so when the pile foundation is applied to a deep foundation pit, the piles need to be spliced to ensure that the pile foundation extends into a hard soil layer.
The commonly used splicing method of the tubular pile at present comprises a welding pile splicing method, a flange plate pile splicing method and the like. The welding pile splicing method needs to clean the pile head before pile splicing, then fix the lower pile, lift the upper pile to aim at the lower pile, form the upper pile and the lower pile into a whole through welding, and need to ensure continuous and full welding seams during welding. However, the field welding pile splicing is affected by the limits of construction conditions, personnel quality and time, and the welding pile splicing has the defects of quality guarantee incapability, high safety risk and the like, so that the application and popularization of the reinforced concrete hollow pipe pile in the aspects of reinforcing foundation and shoreside slope supporting are severely limited. The flange pile splicing method is characterized in that an upper pile and a lower pile are respectively fixed on a flange and aligned, and then the flanges are screwed and fixed by bolts, so that the upper pile and the lower pile are connected. The flange pile splicing method is high in speed and good in quality, but the construction process is complex, the pile splicing cost can be greatly increased, and the application range of the tubular pile is limited.
Therefore, it is highly desirable to design a pile splicing structure that is fast, reliable and low in cost.
