某在建工程框架柱分批置换混凝土加固技术

The reinforcement technology of a construction in progress frame column partial replacement concrete

针对某在建工程框架柱混凝土强度等级偏低的情况,确定了分批置换混凝土加固方案,对置换期间被置换柱及其周围构件进行沉降变形监测,并对结构卸荷系统进行了承载能力与稳定性监测,实践证明,该方案取得了良好的加固效果。

According to the situation of low strength of a construction in progress frame column,determined the partial replacement concrete reinforcement scheme,made sedimentation deformation monitoring to replacement column and its surrounding members during displacement period,made bearing capacity and stability monitoring to structure unloading system,the practice proved that this scheme achieved good reinforcement effect.
