Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology for pipe penetration through walls, specifically, to a waterproofing device for directly buried pipe penetration through walls. Background Technology

[0002] Waterproofing is required where buried pipelines pass through walls, mainly because the surrounding wall structure inevitably contains construction joints, material shrinkage joints, and annular gaps between the pre-embedded sleeve and the pipeline. In addition, thermal expansion and contraction, vibration, or foundation settlement during pipeline operation may cause minor displacements, and these gaps and gaps can form seepage channels. At the same time, the pipeline is buried in the underground environment and is subjected to continuous soil moisture and groundwater pressure. Moisture can easily seep into the room or erode the wall structure through these channels. Therefore, effective waterproofing measures must be implemented to seal these potential paths.

[0003] Traditional waterproofing devices mostly rely solely on sealing rings for waterproofing, resulting in poor waterproofing performance. Furthermore, sealing rings have a shorter lifespan compared to other rigid structures, and replacing them is a cumbersome process. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof device for direct-buried pipes penetrating walls, which solves the problems of poor waterproofing effect and cumbersome replacement of sealing rings in the existing technology, which only relies on sealing rings.

[0007] As a preferred embodiment of the above technical solution, the packing sealing mechanism further includes a sealing locking ring, which is movably sleeved on the outer wall of the sealing core tube.

[0008] As a preferred embodiment of the above technical solution, a support block is fixedly installed on the side of the sealing locking ring, and a positioning bolt is threaded onto the support block.

[0009] As a preferred embodiment of the above technical solution, the end of the positioning bolt is movably abutted against the outer wall of the sealing core tube.

[0010] As a preferred embodiment of the above technical solution, a sealing ring is fixedly connected to the left side of the sealing locking ring, and the sealing ring is movably fitted to the end of the through-wall sleeve.

[0011] As a preferred embodiment of the above technical solution, an annular gap is formed between the outer wall of the sealing core tube and the inner wall of the through-wall sleeve, and the inner cavity of the annular gap is filled with sealing filler.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the overall design of the filler sealing mechanism, allows filler to be added from the injection nozzle to seal the connection. Furthermore, through the overall design of the sealing locking ring, the connection can be sealed with the sealing ring, thus achieving a double sealing function.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: a waterproof device for direct-buried pipes penetrating walls, comprising: Well wall 1 and working steel pipe 11; The packing sealing mechanism 2 is installed on the well wall 1 and the working steel pipe 11. The packing sealing mechanism 2 is used to seal the connection with the help of packing. The packing sealing mechanism 2 includes a through-wall sleeve 21 and a sealing core tube 24. A fixing ring plate 22 is fixedly connected to the outer wall of the through-wall sleeve 21. The through-wall sleeve 21 and the fixing ring plate 22 are located inside the well wall 1. An injection nozzle 23 is fixedly connected to the outer wall of the through-wall sleeve 21. A limiting ring 25 is fixedly sleeved on the outer wall of the sealing core tube 24. An annular gap is formed between the outer wall of the sealing core tube 24 and the inner wall of the through-wall sleeve 21. The inner cavity of the annular gap is filled with sealing packing. During construction, the through-wall sleeve 21 and the fixing ring plate 22 are pre-embedded inside the well wall 1. Then, the working steel pipe 11 and the sealing core tube 24 are inserted into the interior of the through-wall sleeve 21 as a whole. At this time, the limiting ring 25 can limit the insertion position of the through-wall sleeve 21. Afterward, the sealing packing can be filled into the annular gap between the outer wall of the sealing core tube 24 and the inner wall of the through-wall sleeve 21 from the injection nozzle 23 to seal the area.

[0017] As one implementation method in this embodiment, such as Figure 3 As shown, both ends of the sealing core tube 24 are fixedly installed with mating ring plates 241. The mating ring plates 241 are fixedly sleeved on the outer wall of the working steel pipe 11. The inner cavity of the sealing core tube 24 is filled with a heat insulation layer 242. Through the cooperation of the sealing core tube 24 and the mating ring plates 241, the heat insulation layer 242 can be restricted to the outer wall of the working steel pipe 11, thereby improving the heat insulation capacity of the outer wall of the working steel pipe 11 at the connection.

[0018] As one implementation method in this embodiment, such as Figure 1 As shown, the packing sealing mechanism 2 also includes a sealing locking ring 26, which is movably sleeved on the outer wall of the sealing core tube 24. A sealing ring 261 is fixedly connected to the left side of the sealing locking ring 26. The sealing ring 261 is movably fitted against the end of the through-wall sleeve 21. When the working steel pipe 11 and the sealing core tube 24 are inserted into the interior of the through-wall sleeve 21 as a whole, the sealing core tube 24 will drive the sealing locking ring 26 to move, causing the sealing ring 261 to abut against the end of the through-wall sleeve 21 for sealing.

[0019] As one implementation method in this embodiment, such as Figure 4 As shown, a support block 262 is fixedly installed on the side of the sealing locking ring 26. A positioning bolt 263 is threaded onto the support block 262. The end of the positioning bolt 263 movably abuts against the outer wall of the sealing core tube 24. During production, the sealing locking ring 26 is installed on the outer wall of the sealing core tube 24. During installation, the sealing locking ring 26 is sleeved on the sealing core tube 24 and then moved to the designated position. Subsequently, the positioning bolt 263 is tightened so that it abuts against the outer wall of the sealing core tube 24, thus completing the installation of the sealing locking ring 26. The inner wall of the sealing locking ring 26 also includes a rubber ring, which is used to seal the connection between the sealing locking ring 26 and the sealing core tube 24.

[0020] Working principle: During construction, the through-wall sleeve 21 and the fixing ring plate 22 are pre-embedded inside the well wall 1. Then, the working steel pipe 11 and the sealing core pipe 24 are inserted into the through-wall sleeve 21 as a whole. At this time, the limiting ring 25 can limit the insertion position of the through-wall sleeve 21. The sealing core pipe 24 will drive the sealing locking ring 26 to move, causing the sealing ring 261 to abut against the end of the through-wall sleeve 21 for sealing. Afterwards, sealing filler can be filled into the annular gap between the outer wall of the sealing core pipe 24 and the inner wall of the through-wall sleeve 21 through the injection nozzle 23 to seal the area, thereby achieving the function of double sealing.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
