Embodiment Construction
[0028] The construction method of the concrete pouring pile as an embodiment of the present invention comprises the following steps:
[0029] 1) if figure 1 As shown, two concentric inner and outer casings 2 and 3 nested in the foundation 1 are buried. Between the inner casing 2 and the outer casing 3, pressure injection is used as filling for forming a concrete pouring temporary form. The thick mud 4 of the material, the soil in the inner casing 2 is taken out to the ground to form a pile hole. At this time, the above-mentioned soil extraction can be carried out in various ways, such as auger drilling, drilling bucket soil extraction, etc. . Here, the embedding operation of the above-mentioned inner casing 2 and the outer casing 3 is carried out by using a high-frequency hydraulic vibratory hammer 8, and the above-mentioned inner and outer casings 2, 3 are vibrated and driven into the water surface A until the bottom of the pile is inserted into the foundation 1, reaching B...
