Plugging Performance Optimization Tests of Grouting Material for Sudden Water Inflow of Underground Engineering Construction

Abstract:

Sudden water inflow is the typical geological hazard during the construction period of underground, especially for the karst area. According to a new type of polymer chemical grout material called Malisan, plugging performance optimization tests of different grouting material had been carried out, such as ordinary cement, superfine cement and special cement of HSC, the geo time, consolidating strength, anti-erosion property and comprehensive properties of grouting harnessing had been systematically analyzed and compared. Test results showed that the new type of polymer chemical grout material has the significant characteristics of controllable gel time, high consolidating strength, anti-scour performance, water swelling and extremely strong permeability, it is more effective than conventional grouting material for grouting harnessing of seepage, water spraying and water inflow with high water pressure, in addition, it is convenient for transportation, material configuration and process operation.
