Comprehensive reinforcement method for improving bearing capacity of concrete pier column by wrapping steel pipe
The invention discloses a comprehensive reinforcing method for an outer wrapping steel pipe of a concrete pier column. The method is characterized in that according to the steel pipe wrapping method and the self-compacting shrinkage-compensating concrete filling method, the wrapping steel pipes are tightly hooped to the two sides of the concrete pier column through shear force nails, and the existing pier column and the wrapping steel pipes are connected through self-compacting shrinkage-compensating concrete post-pouring belts. And meanwhile, reinforcement is conducted through the construction steps of cleaning and leveling of the contact face, precise positioning and drilling, precise hoisting and the like, and the bearing capacity and the shear capacity of the reinforced pier column are greatly improved. And pollutant emission can be reduced to the maximum extent in the construction process. The strength of the reinforced structure can reach 60% of the standard strength within 6 hours, and the reinforced structure can be completely put into use within 3 days.
本发明公开了一种混凝土墩柱的外包钢管综合加固方法。其特征在于所述钢管外包法与自密实补偿收缩混凝土填充法：所述外包钢管通过剪力钉紧箍于混凝土墩柱两侧，在既有墩柱与外包钢管之间通过自密实补偿收缩混凝土后浇筑带相连。同时经过接触面的清理找平，精准定位钻孔，精准吊装等施工步骤进行加固，加固后墩柱的承载能力，抗剪能力得到很大的提升。在施工过程中能够最大程度减少污染排放。加固结构能在6小时内能够达到标准强度的60％，3天内便可以完全投入使用。
