Abstract

The invention discloses a grouting port blockage device and a method for grouting by adopting the device. The grouting port blockage device comprises a pulp receiving pipe; a positioning cylinder andmultiple annular gaskets arranged at intervals sleeve the pulp receiving pipe; rubber sleeves are arranged between every two adjacent annular gaskets; a limiting boss fixedly connected with the pulp receiving pipe and used for cooperating with a grouting port is arranged at the lower end of the pulp receiving pipe under the annular gasket at the lowermost end; at least one waterstop is bonded on the outer wall of the limiting boss and under the limiting boss; when the positioning cylinder is pushed down, the annular gaskets also move down; under the extrusion effect of the positioning cylinder, the rubber sleeves are gradually deformed as a spherical shape; and meanwhile, the annular gaskets and the rubber sleeves are fixed in the deformed position through the positioning cylinder and thelimiting boss. The grouting port blockage device and the method for grouting by adopting the device have the advantages of good blockage effect, capability of recycling the blockage device, convenience to use and firm structure.

Description

technical field [0001] The invention relates to a construction project, in particular to a blocking device for a grouting port and a grouting method using the device. Background technique [0002] In surface grouting construction, the output pressure of the mixer is often used as a reference for the grouting pressure, but the actual grouting pressure in the hole is less than this value. When the final pressure is used, the grouting hole is often closed and the grouting valve is installed, which is a waste of time and a waste of time. Cause material waste, and easily cause pipe burst. In order to prevent the phenomenon of grouting and pipe bursting during the grouting process, the State Intellectual Property Office of China announced on June 19, 2013, the announcement number is 203007953, an inflatable grouting stopper for hollow grouting bolts , including an annular inflatable bag, on which an air-inflating hole and an air-leakage-proof structure are arranged; the inflatabl...
