Problems solved by technology
The disadvantage is that the grouting pipe wrapped in felt or plastic cloth, when the grouting end of the valve is connected to a large grouting machine to start pouring, the pre-buried cloth or plastic bag wrapped grouting pipe is extremely easy to be overflowed by the grouting liquid under high pressure Ejection, pulp run-out, lead to repeated construction, bring safety hazards and waste of materials, prolong repair time, and low construction efficiency

The invention provides a grouting leaking stoppage nail. The grouting leaking stoppage nail comprises a grouting pipe; one end of the grouting pipe is in screwed fit connection with a valve, and the other end of the grouting pipe is in screwed fit connection with an external thread I formed in one end of a T-shaped hollow external thread pipe through a formed internal thread I; the middle optical axis section of a T-shaped hollow external thread pipe body is sleeved with a gasket; an optical axis section between the gasket and the T-shaped pipe end of the T-shaped hollow external thread pipe is coaxially sleeved with an expansion ring; the axial length L of the expansion ring is greater than the axial length H of the optical axis section; and while the T-shaped hollow external thread pipe is screwed into the grouting pipe, the expansion ring is axially extruded and flattened by the gasket and the end of the T-shaped pipe and then radially expands and deforms, and the grouting pipe and a ground prefabricated hole sealing plug are fixedly connected into a whole through the expansion ring which radially expands and deforms. The grouting leaking stoppage nail is simple in structure, convenient to connect, high in flow, high in efficiency, low in cost, simple and convenient to install, good in treatment effect, economical and practical, and the valve and the grouting pipe can be recycled.
Description
technical field [0001] The invention belongs to the technical field of filling structures for waterproof and plugging engineering, and particularly relates to a grouting plugging nail. Background technique [0002] In the construction industry, such as concrete floor subsidence repair, concrete hollowing is not compact, basement floor seepage, water, it is used for waterproof plugging of chemical grouting liquid such as polyurethane, epoxy resin, water curing, water glass, cement slurry, etc. Occasionally, professional tools applied to high-pressure grouting and plugging construction are required. [0003] In the prior art, one of the professional construction tools for high-pressure grouting plugging is a water-stopping needle, with an inner hole of only 3 mm and a small flow rate, which cannot meet the needs of large-area plugging occasions. Another is to install a quick-open valve at the grouting inlet end of the DN15 grouting pipe, wrap a wool cloth or a plastic bag at ...
