CONSTRUCTION TECHNOLOGY OF CAVE-IN FORWARD GROUTING FOR MUNICIPAL SUBWAY PROJECT IN COASTAL AREA
Taking the construction of the tunnel of Qingdao metro line 4 as an example,this study introduces the new construction technology of progressive grouting reinforcement in the construction of the municipal subway tunnel in coastal area,which not only ensures the damage of underground pipeline caused by the excessive grouting pressure,but also ensures the damage of the underground pipeline caused by the ground up lift.It also solves the problem that the grouting effect cannot be achieved because the grouting pressure is too small,which can provide reference for the grouting treatment of municipal subway tunnel collapse.
