NOVELTY - Method for grouting and plugging of cable conduits through-holes comprises using raw materials and tooling in the grouting plugging method including two-component grouting guns, quick-setting flame-retardant foaming materials, films and adhesive tapes, where quick-setting flame-retardant foaming materials include A component and B component, gluing the cut film on the surface of the cable duct, after 10-15 seconds, component A of the quick-setting flame-retardant foaming material and component B of the quick-setting flame-retardant foaming material start to undergo a foaming reaction for curing, and the complete solidification time is 1-3 minutes, after solidification is completed, completing the blocking of cable. USE - Method for grouting and plugging of cable conduits through-holes used in pipeline plugging field, cable laying and cable underground laying and daily maintenance related to fireproof, waterproof and small animal entering. ADVANTAGE - The method provides cable pipe through hole grouting plugging method with convenient and fast operation, excellent sealing effect, wide application range, grouting sealing material having excellent flame-retardant insulating performance, 5-15 times of adjustable foaming times and adjustable foam body strength, and satisfies for different cable engineering permanent or semi-permanent fast plugging requirement. The flame retardant foaming material has excellent permeability, good bonding performance with the cable and rock, satisfy cable pipeline irregular cavity and the pipeline containing multiple cable fast and efficient plugging requirements. DETAILED DESCRIPTION - Method for grouting and plugging of cable conduits through-holes comprises (1) using raw materials and tooling in the grouting plugging method including two-component grouting guns, quick-setting flame-retardant foaming materials, films and adhesive tapes, where quick-setting flame-retardant foaming materials include A component and B component, the inner cavity of the two-component grouting gun is divided into two parts, namely A cavity and B cavity, the A cavity is filled with the quick-setting flame-retardant foam material A component, and the B cavity is filled with the quick-setting flame-retardant foam material B group share, the steps of the method include the first step, when the cable duct needs to be blocked, cutting the film according to the shape and size of the cable, so that the film can pass through the cable, (2) tearing off the adhesive tape release paper, (3) gluing the cut film on the surface of the cable duct, in the A chamber of the two-component grouting gun, the A component of the quick-setting flame-retardant foaming material is poured, and in the B cavity of the two-component grouting gun, the B component of the quick-setting flame-retardant foaming material, (4) opening a small hole on the surface of the film, using a two-component grouting gun to inject the mixed quick-setting flame-retardant foaming material A component and quick-setting flame-retardant foaming material B group into the cable duct through the small hole share, (5) after 10-15 seconds, component A of the quick-setting flame-retardant foaming material and component B of the quick-setting flame-retardant foaming material start to undergo a foaming reaction for curing, and the complete solidification time is 1-3 minutes, after solidification is completed, completing the blocking of cable.
