Description

Technical Field

[0001] This utility model belongs to the field of water supply and drainage technology, and in particular relates to a pre-embedded protective component for sewer pipes. Background Technology

[0002] Pre-embedded sewer pipes refer to a construction technique in which the sewer pipe system is pre-buried underground or inside the wall during the construction of a building project. This technique is usually completed during the construction phase of the main structure of the building. The purpose is to ensure that the sewage and wastewater discharge function can be smoothly realized after the building is put into use, while avoiding damage to the building structure caused by later trenching and installation.

[0003] In construction engineering, the sealing and waterproofing performance of the pre-embedded installation of drainage pipes directly affects the long-term safety and maintenance costs of buildings. However, simply inserting pipes and filling them with cement may lead to problems such as seepage and leakage, especially at the contact points between the pipes and the walls. Due to thermal expansion and contraction or foundation settlement, gaps can easily form, allowing water to seep into the wall and causing serious consequences such as wall corrosion and mold. Therefore, it is necessary to provide a protective component for pre-embedded drainage pipes, which uses an elastic sealing method to address the sealing effects of thermal expansion and contraction of the wall or foundation settlement on the pre-embedded location. At the same time, multiple sealing treatments are used to effectively prevent water seepage. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-embedded protective component for sewer pipes, which adopts an elastic sealing method to cope with the sealing effect caused by thermal expansion and contraction of the wall or foundation settlement on the pre-embedded position.

[0021] In the following description, embodiments of the pre-embedded protective component for drain pipes of this utility model will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates an embodiment of a pre-embedded protective component for a drain pipe, comprising a pre-embedded pipe 1, into which a drain pipe 2 is inserted. A sealing assembly 3 is provided on the surface of the pre-embedded pipe 1. The sealing assembly 3 includes a water-stop plate 31 fixedly connected to the top of the surface of the pre-embedded pipe 1. A rubber bushing 32 is fitted onto the surface of the pre-embedded pipe 1, and a connecting piece 33 is fixedly connected to the top of the rubber bushing 32. Multiple screws 34 penetrate the top of the water-stop plate 31, with the bottom ends of the screws 34 extending to the bottom of the water-stop plate 31 and threadedly connected to the connecting piece 33. A sealant 35 is filled to the top of the surface of the rubber bushing 32, and a sealant 4 is filled to the top of the surface of the pre-embedded pipe 1. A polymer waterproof coating 5 is applied above the sealant 4. A connector 6 is fixedly connected to the top of the pre-embedded pipe 1, and a shrink ring 7 is fixedly connected to the inner wall of the connector 6. The surface of the drain pipe 2 is tightly fitted to the inner wall of the shrink ring 7. Through the combined use of the connector 6 and the shrink ring 7, the sealant protects the drain pipe 2. The system constrains the flow of water to ensure that the pre-embedded pipe 1 and the drain pipe 2 remain connected. Simultaneously, with the combined use of the return groove 11 and the return hole 12, any seepage that may exist on the surface of the drain pipe 2 can be returned, allowing the seepage to re-enter the inner cavity of the pre-embedded pipe 1, effectively preventing seepage between the pre-embedded pipe 1 and the wall. A sealing cover plate 8 is fitted onto the bottom of the surface of the pre-embedded pipe 1, and a sealing ring 9 is bonded to the top of the sealing cover plate 8. The top of the sealing ring 9 is tightly fitted to the wall. Multiple screws 10 are distributed in a ring at the bottom of the sealing cover plate 8, with the top of the screws 10 penetrating to the top of the sealing cover plate 8 and being fixedly connected to the wall. Through the combined use of the sealing cover plate 8, the sealing ring 9, and the screws 10, while installing and fixing the pre-embedded pipe 1, the contact point between the pre-embedded pipe 1 and the lower part of the wall is sealed again, thereby improving the sealing effect of the pre-embedded pipe 1 after pre-embedding. A return groove 11 is opened at the top of the connector 6, and multiple return holes 12 are opened at the bottom of the inner cavity of the return groove 11.

[0023] Working principle: When using this utility model, the user places the rubber bushing 32 on the surface of the embedded pipe 1, ensuring that the bottom of the waterstop 31 is in contact with the top of the connecting piece 33. The rubber bushing 32 is then installed and fixed with screws 34. The embedded pipe 1, along with the rubber bushing 32, is then inserted into the wall. A sealant 35 is then filled around the surface of the embedded pipe 1 to seal the pipe and the wall support. A sealant 4 is then filled on top of the sealant 35 to cover and seal the surface of the waterstop 31 and the embedded pipe 1. After the sealant 4 has completely solidified, a layer of polymer waterproof coating 5 is applied to the top of the sealant 4. A sealing cover 8 is then placed on the bottom of the embedded pipe 1, ensuring that the top of the sealing ring 9 is in contact with the wall. Screws 10 are then inserted into the wall to fix the sealing cover 8. Finally, the drain pipe 2 is inserted into the cavity of the embedded pipe 1 and elastically clamped by the shrink ring 7.

[0024] In summary, the pre-embedded protective component for the drain pipe, through the setting of the sealing component 3, provides an elastic seal between the pre-embedded pipe 1 and the wall. At the same time, with the combined use of the leak-stopping agent 4 and the polymer waterproof coating 5, the pre-embedded pipe 1 and the wall are sealed and waterproofed, thus achieving the purpose of elastic compression sealing and strong sealing and waterproofing capabilities.
