Grouting construction method
The invention discloses a grouting construction method. A pressing cover plate assembly is used for plugging a pre-embedded grouting tube. The pressing cover plate assembly comprises a cover plate body and a rubber water stop gasket, wherein a ring-shaped groove for accommodating the rubber water stop gasket is formed in the cover plate body; and the cover plate body and the pre-embedded grouting tube are respectively provided with clip key structures which are engaged with each other. The grouting construction method is characterized by comprising the following steps: positioning the pre-embedded grouting tube in a tunnel to be subjected to grouting construction or a rock and soil layer outside a basement; enabling the grouting tube to penetrate through the pre-embedded grouting tube and to insert into the tunnel or the rock and soil layer outside the basement, and then starting grouting; after the grouting is ended, withdrawing the grouting tube out of the pre-embedded grouting tube; and pressing the pre-embedded grouting tube by the pressing cover plate assembly, so that a tube opening of the pre-embedded grouting tube is sealed. The grouting construction method can effectively prevent unconsolidated slurry or underground water outside the tunnel or the basement from entering the tunnel along the open pre-embedded grouting tube, is convenient in construction, less in time consumption and convenient for maintaining and replacing.
