Background The wall-penetrating pipeline is widely applied to various projects such as construction, water conservancy, municipal administration and the like, and is mainly used for realizing functions such as fluid conveying, line penetrating and the like. The wall penetrating pipeline needs to penetrate through various walls such as a concrete wall body and a masonry wall body, gaps between the pipeline and the wall body are main channels for seepage, if the sealing seepage prevention treatment is improper, the problems of water leakage and water seepage are very easy to occur, the structural strength of the wall body can be damaged, the pipeline body is eroded, the normal operation of peripheral equipment can be possibly influenced, the internal environment of a building is possibly damaged, potential safety hazards can be caused when serious conditions are severe, and the later maintenance cost is increased. In the prior art, for the anti-seepage treatment of a wall penetrating pipeline, sealing materials such as sealing glue, water stop strips, waterproof coiled materials and the like are wrapped on the outer wall of the pipeline, filling grouting materials are adopted, or a simple bulge structure is arranged on the outer wall of the pipeline, so that seepage risks are reduced. However, the above methods have obvious defects: (1) The sealing material is influenced by factors such as temperature change, wall settlement, pipeline vibration and the like for a long time, is easy to age, crack and fall off, so that the anti-seepage performance is gradually invalid, and the service life is shorter; (2) The grouting filling or simple bulge structure is difficult to realize the uniform and firm combination of the pipeline and the wall body, and the gap is easy to form hollows and gaps to form a new seepage channel; (3) The simple bulge structure does not reasonably optimize the seepage path, the seepage resistance is insufficient, and the seepage prevention effect is limited; (4) The partially optimized structure can obstruct the pouring of concrete around the pipeline, so that the compactness of the concrete is insufficient, and the hidden trouble of seepage prevention is further aggravated. In addition, the joint of the existing pipeline and the wall body is not tight due to material difference and combination, stress concentration is easy to occur, and when the wall body is settled or the pipeline is stressed, the structure is easy to damage, so that the seepage-proofing structure is indirectly damaged.
