PHC tubular pile, namely prestressed high-strength concrete tubular pile. The hollow cylindrical concrete prefabricated member is prepared by adopting a pre-tensioned prestressing centrifugal forming process and steam curing at about 180 ℃ under 10 atmospheric pressures (about 1.0 Mpa), the standard section length is 10m, the diameter is 300-800 mm, and the strength grade of concrete is not less than C80.
At present, the domestic pile pulling method mainly focuses on a static pile pulling method, a high-pressure rotary spraying mud pile pulling method, a vibration immersed tube high-pressure water cutting pile pulling method, a full-rotation CD machine pile pulling method, an FECE full-rotation pile pulling method and the like. Wherein, the static pulling method directly pulls the tubular pile out of the stratum. The construction method has high requirement on the strength of the pile body and is not suitable for pulling out the prefabricated pipe pile. The high-pressure rotary-spraying slurry pile-pulling method is used for carrying out high-pressure rotary-spraying slurry on the periphery of a pile body to destroy soil bodies around the pile body. The disadvantages are that pile breakage is easily caused, the influence of stratum soil compactness is large, stratum disturbance is large, and the pile is not suitable for pulling out the precast pile. The vibration immersed tube high-pressure water cutting pile pulling method utilizes vibration to liquefy soil around a pile and penetrate into a steel tube, and is matched with high-pressure water to destroy the soil between the pile body and the steel tube, so that the side friction resistance of the pile is greatly reduced. The vibration immersed tube high-pressure water cutting pile pulling method is suitable for pile pulling on water, and the pile pulling method is used for pile pulling on land, so that the construction speed is low, and the stratum disturbance is large. The fully-rotary CD machine pile pulling is one of the most advanced methods for clearing underground obstacles at present, and has the advantages of high verticality, adaptability to various complex geologies and no noise. The hydraulic steel sleeve cutting machine has the disadvantages that the rotary cutting speed of the hydraulic steel sleeve is low, mechanical equipment needs to be balanced to press the steel sleeve by virtue of counter force, a crane is needed for walking, and the accurate positioning is difficult. The FECE full-rotation pile pulling method adopts a double-layer sleeve rotation drilling method to cut the soil body around the pile, thereby reducing the side frictional resistance of the pile. The FECE full-rotation pile pulling method has the advantages of wide application range and good construction effect, particularly for inclined piles and buildings sensitive to settlement nearby a site, but the method needs a special FECE full-rotation pile pulling machine and is high in construction cost.
Because the wharf completion data and geological data are incomplete, particularly the completion data of two berthing piers is missing, and the pile length is unclear; in addition, when the wharf is soaked in seawater for twenty years, the welding position of the pile and the quality of the pile can cause the pile to break.
