Embodiment Construction
[0027] As the construction method of the concrete pile of an embodiment of the present invention, it comprises the following steps, at first, as figure 1 As shown in a, at the predetermined pile position in the foundation, a special inner ramming pipe 1 is used, and the inner ramming pipe 1 whose upper end is connected with a fixed diesel hammer 2 and a ramming disc 3 is inserted into a large-diameter outer pipe 4 . Such as figure 1 As shown in b, through the up and down action of the diesel hammer 2, the ramming plate 3 hits the outer tube 4, so that the outer tube 4 and the inner ramming tube 1 sink down at the same time to the design depth, and the inner ramming tube 1 Squeeze out a certain distance from the bottom of the outer tube 4 . Such as figure 1 As shown in c, the above-mentioned internal ramming tube 1 is proposed, and a certain amount of bulk filler 5 is filled into the inner bottom of the outer tube 4 . Such as figure 1 As shown in d, the inner ramming tube 1...
