Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
As shown in fig. 1, the variable connection angle PC construction method pile of the present embodiment includes a connection tongue 1, and a steel pipe pile 2 and a larsen steel plate pile 3 inserted by the connection tongue. As shown in fig. 2 and 3, the connecting tongue and groove 1 includes a shaft portion 101 welded and fixed to the steel pipe pile 2; a locking notch 102 that can be rotated 180 ° about the shaft portion 101; and a hinge fitting 103 for fitting the locking notch 102 to the shaft portion.
