The concrete pouring port 1 6 is located at the upper middle part of the facade, and the concrete pouring port 2 8 is arranged on both sides of the facade. Concrete enters through the concrete pouring port 1 6 and the concrete pouring port 2 8, and is poured and connected with the bottom main structure of the steel-concrete composite column 1 while filling the internal space of the fixed base 2, thereby realizing a firm connection between the fixed base 2 and the steel-concrete composite column 1.

Then, the steel-concrete composite column 1 is placed above the fixed base 2 to ensure that the contact surface of the steel-concrete composite column 1 and the fixed base 2 fits tightly. Next, concrete is poured into the fixed base 2 through the concrete pouring port 1 6 and the concrete pouring port 2 8, and at the same time, the concrete is connected to the bottom main structure of the steel-concrete composite column 1 through the pouring channel 10. After the concrete solidifies, the steel cover plate 3 is assembled on the outer surface of the fixed base 2 by bolts to complete the installation of the reinforcement device.
