Problems solved by technology
However, traditional portal piers mostly adopt reinforced concrete structure. Reinforced concrete portal piers are heavy in weight and poor in ductility, making construction difficult, long construction period, difficult to repair, and high cost
After the strong earthquake, the damage was serious and it was difficult to repair quickly, which caused great difficulties for post-earthquake rescue and disaster relief and huge indirect losses

The invention provides an assembly type steel bridge pier column and an assembly type gate-type steel bridge pier. The assembly type steel bridge pier column comprises a first pier column, a second pier column, a third pier column and energy dissipation columns arranged at the two ends of the second pier column, wherein the energy dissipation columns and the second pier column are coaxial. The first pier column, the second pier column and the third pier column are sequentially and coaxially arranged. The first pier column, the second pier column, the third pier column and the energy dissipation columns are hollow inside. By the application of the technical scheme, assembly is convenient, a damaged component is replaced in time when the component is damaged, and a quick repairing effect ona bridge is achieved.
Description
technical field [0001] The invention relates to the field of bridge pier technology, in particular to an assembled steel pier column and an assembled portal steel pier. Background technique [0002] As we all know, with the rapid development of my country's economy, the number of infrastructure construction has been very large. Many earthquakes at home and abroad have shown that bridge structures, as an important part of the traffic lifeline, play a key role in post-disaster first aid and restoration and reconstruction. However, traditional portal piers mostly adopt reinforced concrete structures. Reinforced concrete portal piers are self-heavy and have poor ductility. The construction is difficult, the construction period is long, and the repair is difficult and costly. After the strong earthquakes, they were severely damaged and difficult to repair quickly, which caused great difficulties and huge indirect losses for post-earthquake rescue and disaster relief. The seismi...
