Embodiment Construction
[0025] The method for making the reaming and grouting PHC pipe piles in soft soil areas of the present invention will be described in conjunction with the accompanying drawings and embodiments.
[0026] The pile end of the sinking PHC pipe pile 1 adopts the enlarged head plate 3, the area of the enlarged head plate 3 is larger than the cross-sectional area of the PHC pipe pile, and the steel plate larger than the cross-sectional area of the PHC pipe pile is used to connect to the bottom pile of the HC pipe pile 1 end, as shown in Figure 2.
[0027] The shape of the enlarged head plate 3 can have various shapes such as square, circular, triangular or elliptical according to the difference in the nature of the formation, and the area of the expanded head plate 3 can be 1.5-3 times of the cross-sectional area of the PHC pipe pile 1. The enlarged head plate 3 can adopt two forms of enlarging the area of the end plate 12 or directly welding a steel plate greater than th...
