Method for treating wide fracture of rock mass and sealing structure

The invention relates to a method for treating a wide fracture of a rock mass and a sealing structure for the method. The method comprises the steps of (a) cleaning the fracture; (b) scraping rapid harding portland cement; (c) pre-burying a slurry inlet pipe and a slurry return pipe; and (d) carrying out grouting. The method has the advantages of being simple to operate, convenient to construct, short in construction period and low in cost. The sealing structure obtained by the method comprises a plugging layer and a filling body; the plugging layer is located on the surface of bedrock and covers an opening of the fracture and is provided with holes allowing the slurry inlet pipe and the slurry return pipe to penetrate through; and the filling body is located in the fracture and is attached to the bottom surface of the plugging layer and the rock mass on the side surface of the fracture. The sealing structure has the advantages of being simple, good in sealing effect and capable of avoiding the phenomenon tha
