Embodiment
[0014] Example: such as figure 1 As shown, the main body of the corrugated thin steel plate-concrete composite hollow section pipe pile in this embodiment includes a corrugated thin steel plate 1, inner concrete 2 and outer concrete 3, and the combination of the three forms a pipe pile.
[0015] Such as figure 1 As shown, the corrugated thin steel plate 1 encloses a closed space, the inner concrete 2 is located inside the corrugated thin steel plate 1 , and the outer concrete 3 is located outside the corrugated thin steel plate 1 . A number of openings are provided on the corrugated thin steel plate 1, through which the inner concrete 2 and the outer concrete 3 are connected and the inner concrete 2 and the outer concrete 3 are integrated. At this time, the corrugated thin steel plate 1 is equivalent to being embedded in the concrete of the pipe pile; in this way, the corrugated thin steel plate 1 can increase the torsional and flexural strength of the pipe pile section, so t...
