This structure, through the stable connection between the outer metal mesh 5 and the reinforcing steel cage 6, facilitates subsequent pouring work, and at the same time, the outer metal mesh 5 can hold the reinforcing steel cage 6 in place. The reinforcing cage 6 and connecting steel bars 4 are wrapped together, ensuring a tight fit between the reinforcing cage 6 and connecting steel bars 4 and the outer wall of the concrete foundation 8, thereby improving the stability of the subsequent foundation reinforcement. The inner metal mesh 7 is glued to the outer wall of the concrete foundation 8. This structure, through the inner metal mesh 7, can wrap and reinforce the concrete foundation 8, and is suitable for cases of minor damage to the concrete foundation 8, effectively preventing the concrete foundation 8 from continuing to crack. The reinforcing cage 6 is set outside the inner metal mesh 7, and the outer metal mesh 5 is set outside the reinforcing cage 6. The outer wall of the fence post 2 is fitted with a sleeve rod 1, and a grouting opening is provided on one side of the sleeve rod 1. The grouting port has a sealing plug 10 inserted inside. A grouting layer 11 is provided inside both the sleeve rod 1 and the fence post 2. This structure facilitates the injection of the grouting layer 11 through the grouting port.
