Embodiment 1
[0047] Such as Figure 1-5 As shown, a steel pipe pile structure provided in this embodiment includes: a steel pipe pile 10 and a corbel 21;
[0048] The side wall of the steel pipe pile 10 is provided with a via hole 12 connecting the inside and outside of the tube cavity 11 of the steel pipe pile 10;
[0049] The corbel 21 is inserted into the via hole 12 so as to slide out from the lumen 11 .
[0050] The present invention is simple in structure and easy to use. After the steel pipe pile 10 is laid in place, the actuator 30 is used to push the end of the corbel 21 from the tube cavity 11 of the steel pipe pile 10 to force the corbel 21 to extend out of the steel pipe from the through hole 12. pile 10, and then form the corbel 21 structure connecting the steel pipe pile 10 and the foundation, which is convenient for construction, less destructive, and low in cost.
[0051] More preferably, this embodiment includes a corbel assembly 20, and the corbel assembly 20 includes mor...
Embodiment 2
[0061] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:
[0062] In this embodiment, one or more corbel assemblies 20 are arranged at intervals in the lumen 11 of the steel pipe pile 10; when a plurality of corbel assemblies 20 are provided, as Figure 6 As shown, the adjacent corbel assemblies 20 are connected by intermediate connecting rods 52 .
[0063] A compression spring 60 is provided in the lumen 11 and at the bottom of the lowermost corbel assembly 20 , and both ends of the compression spring 60 are connected with the lowermost corbel assembly 20 and the steel pipe pile 10 After being compressed, the compression spring 60 tends to force the corbel assembly 20 to move upwards, thereby preventing the corbel 21 from extending out of the through hole 12 .
[0064] Before the steel pipe pile 10 is inserted into the set position of the foundation, the compression spring 60 can prevent the corbel assembly 20 from moving...
