Chemical Grouting Technology for Concrete Seepage Cracks in the Busbar Tunnel and Cable Lane of the Underground Powerhouse of Jinping Secondary Hydropower Station
Chemical grouting technology is used to repair the concrete seepage cracks in the underground workshop of Jinping Secondary Hydropower Station.After the measures of crack surface cleaning,grouting hole drilling,hole washing,grouting nozzle burying,crack enveloping,grouting,closing and coating protection for crack surface,there is no water seepage on the crack surface after treatment.The results of borehole water pressure test show that the chemical grouting construction solves the problem of water seepage in cracks and achieves the expected concrete repair effect.
