In-situ repairing and reinforcing construction method for supporting steel pipe column
The invention belongs to the technical field of bridge engineering construction, and particularly relates to an in-situ repairing and reinforcing construction method for a supporting steel pipe column, which is characterized in that plain concrete is poured in the steel pipe column to improve the compressive bearing capacity of the original structure of the steel pipe column, and a reinforced concrete coating layer is poured on the outer wall of the steel pipe column to improve the tensile bearing capacity of the original structure of the steel pipe column; therefore, the steel pipe column is repaired and reinforced when being subjected to yield deformation due to collision. The method has the beneficial effects that secondary reinforcement of the damaged steel pipe column can be completed under the condition that the supporting steel pipe column and a structure above the column top are not dismantled, in-situ repair and reinforcement of the damaged steel pipe column are achieved, the construction period can be greatly shortened for an urban road-crossing door opening steel pipe column support, and municipal traffic pressure can be relieved.
本发明属于桥梁工程施工技术领域，尤其涉及一种支撑钢管柱原位修复加固施工方法，通过在钢管柱内浇筑素混凝土增大钢管柱原结构的抗压承载能力，通过钢管柱外壁浇筑的钢筋混凝土包覆层提高钢管柱原结构的抗拉承载能力，实现对钢管柱遭受撞击发生屈服变形的修复及加固。本发明的有益效果是：能够在不拆除支撑钢管柱及柱顶上方结构的情况下，完成了对受损钢管柱的二次加固，实现了对受损钢管柱原位修复及加固，对于城市跨路门洞钢管柱支架而言可大大减少施工工期、缓解市政交通压力。
