The spiral groove design of the embodiment increases the water climbing gradient and increases the difficulty of water body permeation from the outer side to the inner side of the building along the sleeve; contributes to waterproofing; meanwhile, because the groove depth of the spiral groove 4 is deep, when concrete is poured after the concrete, the concrete is fully distributed in the spiral groove, even if thermal expansion and cold contraction exist, the groove depth of the spiral groove can offset part of the contact cavity area caused by the mutual contraction of the concrete and the sleeve to a certain extent, and the aggravation of the water seepage degree can be avoided; as shown in fig. 2, a partition plate 10 is further arranged in the sleeve 2, and the flange plate 1, the sleeve 2 and the partition plate 10 are integrally formed; the middle part of the sleeve 2 is provided with a water seepage prevention baffle 3; the outer diameter of the anti-seepage baffle 3 is larger than that of the sleeve 2, and the structure of the anti-seepage baffle 3 not only increases the compressive strength of the sleeve, avoids or reduces the deformation of the sleeve 2, but also blocks the water seepage of the part crossing the spiral groove 4; when the length of the sleeve 2 body is shorter than the required length due to the difference of the building structures, the extension sleeve 12 is used to be connected with the sleeve 2 in a sleeving way, so as to assemble and increase the length of the sleeve 2; the side wall of the sleeve 2 is provided with a bayonet 9, the extension sleeve 12 is provided with a buckle (not shown in the figure) matched with the bayonet 9, and the buckle can be a spring plunger embedded on the extension sleeve or a plastic structure with elastic deformation. To help the positioning and connecting fixation of the sleeve 2 and the extension sleeve; as shown in fig. 5, one end of the extension sleeve 12 has a larger pipe diameter, so as to increase the working space when cables are laid, and on the other hand, since the end with the larger pipe diameter is usually arranged near the inner side of the building, the slope of the pipe diameter change also helps to further prevent water seepage from spreading to the inner side of the building.
As shown in fig. 1 and 2, the flange plate 1, the water seepage prevention baffle plate 3 and the partition plate 10 are integrally parallel to each other; by arranging the water seepage prevention baffle 3, the whole prefabricated modular water blocking flange is not easy to generate transverse displacement in the pouring process or the solidification stage; a plurality of reinforcing ribs 8 are arranged between the water seepage prevention baffle 3 and the sleeve 2 so as to improve the compressive strength of the sleeve 2; according to different processes, different reinforcing ribs 8 can be arranged in the same direction or different directions.
