Ultra-high performance concrete box girder reinforcement construction method
The invention discloses an ultra-high performance concrete box girder reinforcement construction method which mainly comprises the following steps: firstly, carrying out base surface treatment on to-be-reinforced concrete, drilling anchor holes and reinforcing steel bar holes in the to-be-reinforced concrete base surface, implanting reinforcing steel bars and anchor bolts, fixing the reinforcing steel bars, blanking a template, then arranging pouring holes and exhaust holes; and finally, pouring the ultra-high performance concrete into the formwork, and after pouring is completed for a period of time, performing watering curing on the reinforced concrete, and completing reinforcement. According to the ultra-high performance concrete box girder reinforcing construction method, the structural durability can be improved, the service life of a bridge structure can be effectively prolonged, the cracking risk of the box girder is effectively reduced, and the method is suitable for large-span bridge construction.
本发明公开了一种超高性能混凝土箱梁加固施工方法,主要以下步骤,首先对待加固混凝土进行基面处理,在待加固的混凝土基面上进行打锚孔与钢筋孔,植入钢筋与锚栓,对钢筋进行固定,模板下料后,设置灌注孔与排气孔,最后将超高性能混凝土浇筑于模板内,待浇筑完毕后一端时间,对加固后的混凝土进行洒水养生,完成加固。本发明的超高性能混凝土箱梁加固施工方法可提高结构耐久性,能够有效延长桥梁结构使用寿命,有效降低了箱梁开裂风险,适用于大跨径桥梁施工。
