[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] See also Figures 1 to 4 A truss tower side column structure for connecting to a gravity expansion foundation includes a side column 1 with an expansion ring 2 at its bottom end. The side column 1 and the expansion ring 2 form an integral cast-in-place steel structure. This utility model ensures the installation quality and safety of the truss tower side column structure for connecting to a gravity expansion foundation, providing reliable assurance for the smooth implementation of wind power projects.

[0023] Preferably, the side column 1 is connected to the plane of the expansion ring 2 at an inclination angle of 70-80°.

[0024] Preferably, the expanded ring 2 extends outward from the side of the side column 1.

[0025] Preferably, the expandable ring 2 is provided with two circles of screw holes 2.1 along the circumference thereof, so that the screw holes 2.1 of the expandable ring 2 are aligned with the exposed anchor rods 3 on the upper portion of the expandable foundation.

[0026] Preferably, the inner diameter of the screw hole 2.1 is consistent with the diameter of the anchor rod 3 of the gravity expansion foundation, and the screw hole 2.1 and the anchor rod 3 are connected by a high-strength bolt.

[0027] The working principle of this embodiment is as follows:

[0028] Transport the prefabricated structure to the construction site. Use a crane to lift the side column 1 to the predetermined position to ensure that its verticality and flatness meet the requirements. Use a spirit level and theodolite to position and calibrate the side column 1 to ensure that its verticality and position are accurate. Check whether the screw holes 2.1 on the expansion ring 2 are aligned with the anchor rods 3 in the foundation. Pass the high-strength bolts through the screw holes 2.1 on the expansion ring 2 and the anchor rods 3 in the foundation to ensure a tight connection. Use a bolt wrench to tighten the bolts to ensure the strength and stability of the connection. Use the spirit level and theodolite to calibrate the side column 1 again to ensure that its verticality and flatness meet the design requirements. Check all connection parts to ensure that there are no loose or missing parts.
