摘要： PURPOSE: A grouting method for subsidized road and weak soil foundation is provided to minimize the risk of resubsidence of road by injecting grout milk between a soil layer and a lean concrete layer and between the lean concrete layer and a main concrete pavement layer. CONSTITUTION: A grouting method for subsidized road and weak soil foundation is as follows. A plurality of injection grooves for injection of grout milk and a plurality of confirmation grooves for confirming the injection of grout milk are bored in subsidized road or weak soil foundation to a soil layer(S100). An injection device is inserted and fixed in the injection grooves(S200). Water is injected into the injection device to confirm the size of an air gap and grout milk to be injected is prepared(S300). A feed hose is connected to the injection device to individually inject the grout milk(S400). A backflow prevention valve is closed to prevent backflow(S500). After 3-24 hours, grout milk is injected into an air gap between the concrete layer and a main concrete pavement layer(S600). A valve of the injection device is closed to prevent the backflow of grout milk(S700). The grout milk injected is solidified(S800). The injection device is removed from the injection groove(S900). It is determined whether the main concrete pavement layer is raised by the grout milk injection(S1000).
