The adjacent ends of the bridgewise steel hoop and the longitudinal bridgewise steel hoop of the pier body are connected by tie rods.

The two ends of the connecting screw between the steel hoop of the steel pipe column and the steel hoop of the pier body cross bridge direction and the steel hoop of the pier body longitudinal bridge direction are respectively installed on the steel hoop of the steel pipe column and the cross bridge direction steel hoop of the pier body. The hoop and the longitudinal bridge of the pier body are on the connecting steel plate of the upper and lower channel steel of the steel hoop.

The connection system described in the utility model is processed into a complete set of connection system through mechanical calculation, with fixed position and unique bar, more standardized use, firm connection and stronger safety. The lead screw can be adjusted, which can be applied to pier bodies of different sizes and bracket systems with different spacing, and has strong adaptability. The connection system is self-contained, and the installation and disassembly can be completed only by loosening a few fixed bolts. This "clothes-style" installation and disassembly method can save a lot of precious time, and the connection system can be reused.

The utility model has the following beneficial effects: 1) the stability of the steel pipe column is enhanced; 2) the structure is simple and convenient to manufacture; 3) it can be reused; 4) it has wide applicability and can be used for various pier constructions.
