The treatment measures for leakage vibration of reinforced concrete columns should be determined according to the degree of concrete quality defects (problems).

Local honeycomb phenomenon

Although the reinforced concrete column leaks vibration, the concrete of the column is basically dense, and there is only a shallow honeycomb phenomenon on the local surface. Under the condition of not affecting the safe use of the column structure, it can be temporarily left untreated and can be supplemented in the next process (plastering). The premise of this situation is that the column reinforcement is not dense and the workability of concrete is good.

Local honeycomb and hole phenomenon

The whole concrete column has beehives and holes; The loose concrete, gravel and mortar film in the honeycomb and holes shall be chiseled clean, chiseled to a dense place, and the concrete on the steel bar shall be cleaned, and then wetted with clear water for 72 hours. Pouring with high-grade micro-expansive concrete, and curing according to regulations.

Large area holes and honeycombs

If there are large-area (volume) holes and honeycombs in the column concrete, which seriously affect the structural safety, the construction should be stopped immediately, and temporary reinforcement measures (such as temporary support measures for beam and slab of load-bearing columns) should be taken to prevent the quality problems (accidents) from further expanding. And report to the construction unit and the construction administrative department (quality supervision station); Entrust the original design unit to prepare the treatment plan or report it to the original design unit for review, and then deal with it according to the plan.
