Description

Technical Field

[0001] This application relates to the technical field of drainage pipes, and in particular to a sewage drainage pipe and a method for installing the same. Background Technology

[0002] Drainage pipelines refer to the systems of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. Drainage pipelines include main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, any pipe that serves a drainage function should be counted as a drainage pipeline.

[0003] During the construction of drainage pipes, to ensure a seal at the connection point, workers apply sealant to the joint after connecting the two pipes. This sealant fills the gaps, achieving a seal between the two pipes. However, because the drainage pipes are placed on the ground, the space near the ground is limited, and visibility is restricted. This makes the sealing process time-consuming and laborious, and may even result in incomplete sealing. Summary of the Invention

[0004] To facilitate the application of sealant to the joints of drainage pipes, this application provides a sewage drainage pipe and its installation method.

[0005] Firstly, the sewage drainage pipe provided in this application adopts the following technical solution:

[0006] A sewage drainage pipe includes a drainage pipe comprising a pipe section, a socket section, and a spigot section. The socket sections and spigot sections of adjacent drainage pipes are interlocked. A first sealing ring and a second sealing ring are sequentially fitted onto the spigot section. The second sealing ring has a cavity for holding sealant and a sealant outlet hole communicating with the cavity. The drainage pipe is provided with a squeezing component for squeezing out the sealant from the second sealing ring.

[0007] By adopting the above technical solution, workers pre-inject sealant into the second sealing ring and then place the second and first sealing rings onto the spigot end. After connecting the spigot and socket ends of adjacent drainage pipes, the sealant in the second sealing ring is squeezed out using a pressing component. The sealant is injected into the gap between the spigot and socket ends through the sealant outlet. By pre-injecting the sealant into the second sealing ring and using the pressing component to directly squeeze the sealant onto the drainage pipe joint, the operation is simplified for workers and the difficulty of the work is greatly reduced.

[0008] Optionally, the inner side of the second sealing ring is provided with an injection hole communicating with the cavity, and the inner side of the second sealing ring is fixedly provided with a flange that can cover the injection hole.

[0009] By adopting the above technical solution, after the sealant is injected into the cavity through the injection hole, the flange can seal the injection hole, making it difficult for the sealant to leak out when it is extruded. When the second sealing ring is fitted onto the insertion part, the position of the injection hole also prevents sealant leakage.

[0010] Optionally, the insertion portion is provided with a positioning groove that matches the flange, and the flange is engaged in the positioning groove.

[0011] By adopting the above technical solution, the positioning groove makes it easier for workers to install the second sealing ring in the corresponding position, so that the second sealing ring is less likely to slip off or shift when the two drainage pipes are connected and installed.

[0012] Optionally, an extension tube is fixedly provided on the second sealing ring, and the extension tube is connected to the ointment outlet hole.

[0013] By adopting the above technical solution, the extension tube can be inserted into the gap between the spigot and the socket, allowing the sealant to be injected directly into the inside, expelling the air inside, avoiding air bubbles, and helping to fill the gap between the spigot and the socket.

[0014] Optionally, a sealing film is fixedly provided at the opening of the extension tube, and a slit is provided on the sealing film.

[0015] By adopting the above technical solution, the cover can cover the opening of the extension tube and block external debris, making it difficult for debris to enter the extension tube.

[0016] Optionally, the extrusion assembly includes an extrusion ring sleeved on the drainage pipe, connecting rods hinged to both ends of the extrusion ring, nuts threaded onto the connecting rods, and connecting pipes fixedly disposed on the socket; the connecting rods and connecting pipes between adjacent drainage pipes are interlocked.

[0017] By adopting the above technical solution, inserting the connecting rod into the connecting pipe enables the alignment connection between the two drainage pipes, preventing them from becoming misaligned. Continuously rotating the nut moves the compression ring, causing it to squeeze out the sealant from the second sealing ring and press it tightly against the joint of the drainage pipes, thus achieving a sealing effect.

[0018] Optionally, a limiting block is fixedly installed on the drainage pipe, and a limiting plate is fixedly installed on the extrusion ring. The limiting plate has a limiting groove that matches the limiting block.

[0019] By adopting the above technical solution, the sliding connection between the limiting block and the limiting plate plays a limiting role in the movement of the extrusion ring, making it less likely for the extrusion ring to become skewed during the movement.

[0020] Optionally, a positioning plate is hinged to the limiting plate, and the positioning plate has a notch that matches the limiting block. The positioning plate can rotate until the limiting block is engaged in the notch.

[0021] By adopting the above technical solution, after the positioning plate and the limiting block are snapped together through the notch, when the drainage pipe is lifted by the crane, the staff can move the drainage pipe by the connecting rod, thereby adjusting the position and angle of the drainage pipe, making it easier to align and connect the two drainage pipes.

[0022] Optionally, a magnet is fixedly provided on the positioning plate, and when the limiting block is engaged in the notch, the magnet can be attracted to the limiting plate.

[0023] By adopting the above technical solution, the magnet can make the positioning plate and the limiting plate attract each other, making it difficult for the positioning plate and the limiting block to separate.

[0024] Secondly, the present application provides a method for installing a sewage drainage pipe, which adopts the following technical solution:

[0025] A method for installing a sewage drainage pipe includes the following steps:

[0026] Step 1: Use a crane to lift the drain pipes, clean the socket and spigot ends of the two drain pipes that need to be connected, put the second sealing ring filled with sealant on the spigot end, and then put the first sealing ring on the spigot end.

[0027] Step 2: Rotate the positioning plate to lock the limiting block in the notch, and move the drain pipe by connecting the rod so that the connecting rod is inserted into the connecting pipe and the spigot is inserted into the socket.

[0028] Step 3: Rotate the positioning plate again to release the extrusion ring. Move the extrusion ring to press against the second sealing ring. Install the nut on the connecting rod. By rotating the nut, the extrusion ring is moved to squeeze out the sealant from the second sealing ring.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The operator injects sealant into the second sealing ring beforehand and then places the second and first sealing rings onto the spigot. After connecting the spigot and socket of the adjacent drain pipes, the sealant in the second sealing ring is squeezed out using a pressing component. The sealant is injected into the gap between the spigot and socket through the discharge hole. By pre-injecting the sealant into the second sealing ring and using the pressing component to directly squeeze the sealant onto the drain pipe joint, the operator's operation is simplified, greatly reducing the difficulty of the work.

[0031] 2. Inserting the connecting rod into the connecting pipe enables the alignment of the two drainage pipes, preventing them from becoming misaligned. Continuously rotating the nut moves the compression ring, causing it to expel the sealant from the second sealing ring and press it firmly against the joint of the drainage pipes, achieving a sealing effect.

[0037] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.

[0038] This application discloses a sewage drainage pipe. Please refer to... Figure 1 and Figure 2A sewage drainage pipe includes a drainage pipe 1. The drainage pipe 1 includes a pipe section 11, a socket section 12 integrally formed at one end of the pipe section 11, and a spigot section 13 integrally formed at the other end of the pipe section 11. The socket section 12 is flared, allowing the spigot section 13 of another drainage pipe 1 to be inserted, thereby achieving connection between adjacent drainage pipes 1. A first sealing ring 21 and a second sealing ring 22 are sequentially fitted onto the spigot section 13, with the first sealing ring 21 being closer to the outer side. Both the first sealing ring 21 and the second sealing ring 22 are made of rubber. A sealing groove is formed on the spigot section 13, and the first sealing ring 21 is engaged in the sealing groove, so that when the spigot section 13 is inserted into the socket section 12, the first sealing ring 21 can remain straight and not easily twisted.

[0039] Please refer to Figure 2 A cavity 221 is formed within the second sealing ring 22, extending in a complete annular shape along the circumference of the second sealing ring 22. The cavity 221 is filled with polyurethane sealant. A sealant outlet hole 222 is formed on the side of the second sealing ring 22 near the first sealing ring 21, communicating with the cavity 221, and evenly distributed along the circumference of the second sealing ring 22. A compression assembly is provided on the drain pipe 1 to expel the sealant from the second sealing ring 22. When the spigot 13 is inserted into the socket 12, the compression assembly expels the sealant from the cavity 221 through the sealant outlet hole 222, thereby filling and sealing the gap between the spigot 13 and the socket 12, achieving further sealing between adjacent drain pipes 1.

[0040] Please refer to Figure 2 To facilitate the injection of sealant into the second sealing ring 22, a sealant injection hole 223 communicating with the cavity 221 is provided on the second sealing ring 22. The sealant injection holes 223 are evenly distributed along the circumference of the second sealing ring 22. The sealant injection holes 223 are located on the inner surface of the second sealing ring 22, and a flange 224 made of rubber is fixedly provided on the inner surface of the second sealing ring 22. In its natural state, the flange 224 fits against the inner surface of the second sealing ring 22, thereby sealing the sealant injection hole 223 and preventing sealant from leaking out of the cavity 221. When injecting sealant, the flange 224 is flipped open, exposing the sealant injection hole 223. After the cavity 221 is filled with sealant, the flange 224 is flipped open again to reseal the sealant injection hole 223. When the second sealing ring 22 is fitted onto the insertion part 13, the second sealing ring 22 is stretched open, and the flange 224 can further fit onto the second sealing ring 22, improving the sealing effect on the injection hole 223.

[0041] For further details, please refer to Figure 2A plug 2241 is integrally formed on the flange 224, and the number of plugs 2241 is the same as that of the injection holes 223, and they correspond one-to-one. After the sealant is injected into the second sealing ring 22, the flange 224 is flipped, allowing the plugs 2241 to be inserted into the injection holes 223, thereby completely sealing the injection holes 223. The plugs 2241 facilitate the sealing of the injection holes 223 and effectively prevent the sealant from overflowing from the injection holes 223 when the second sealing ring 22 is squeezed.

[0042] Please refer to Figure 2 To facilitate the installation of the second sealing ring 22 on the socket portion 13, a positioning groove 131 is provided on the socket portion 13. When the second sealing ring 22 is fitted onto the socket portion 13, the flange 224 is embedded in the positioning groove 131, thereby ensuring that the second sealing ring 22 remains straight on the socket portion 13 and is not easily twisted. At the same time, it also serves to position the second sealing ring 22, making it easier for workers to install the second sealing ring 22 in a specific position.

[0043] Please refer to Figure 1 and Figure 2 To facilitate the injection of sealant into the gap between the socket 12 and the spigot 13, an extension tube 225 is fixedly installed on the second sealing ring 22. The extension tube 225 corresponds one-to-one with the sealant outlet 222, and is made of rubber. When the spigot 13 is inserted into the socket 12, the extension tube 225 extends into the gap between the socket 12 and the spigot 13, with its opening close to the socket 12. This allows the sealant to diffuse from the inside out when discharged from the extension tube 225, pushing out air from between the socket 12 and the spigot 13. This makes it easier for the sealant to fill the gap between the socket 12 and the spigot 13, significantly reducing the occurrence of air bubbles and voids.

[0044] Please refer to Figure 1 and Figure 2 A sealing sleeve 2251 is fixedly installed on the extension tube 225, with each sleeve corresponding to the extension tube 225. The sealing sleeve 2251 is made of rubber. A cross-shaped cut is provided on the sealing sleeve 2251, allowing it to seal the extension tube 225 in its natural state, preventing external debris from entering the cavity 221 through the extension tube 225 and contaminating the sealant. When the sealant flows out from the extension tube 225, the sealing sleeve 2251 can bend, allowing the sealant to drain normally.

[0045] For details, please refer to Figure 3 and Figure 4The extrusion assembly includes an extrusion ring 31 fitted onto the drainage pipe 1, connecting rods 32 hinged to both sides of the extrusion ring 31, a nut 33 threaded to the end of the connecting rod 32, and connecting pipes 34 fixedly disposed on both sides of the socket 12. One end of the connecting pipe 34 is flared, making it easier to insert the connecting rod 32 into the connecting pipe 34 when connecting adjacent drainage pipes 1, achieving alignment between adjacent drainage pipes 1 and preventing misalignment during connection. When connecting adjacent drainage pipes 1, after the drainage pipe 1 is lifted by a crane, the operator can adjust the position and angle of the drainage pipe 1 by holding the connecting rod 32, facilitating handling and operation. After inserting the connecting rod 32 into the connecting pipe 34, the nut 33 is installed on the connecting rod 32. By continuously rotating the nut 33, the extrusion ring 31 moves towards the second sealing ring 22, causing the extrusion ring 31 to squeeze out the sealant within the second sealing ring 22. After the sealant is squeezed out, the second sealing ring 22 is pressed onto the socket 12 by the extrusion ring 31, thus sealing the gap between the socket 12 and the insertion part 13.

[0046] Please refer to Figure 3 and Figure 4 Limiting blocks 14 are fixedly installed on both sides of the pipe section 11, and limiting plates 311 are fixedly installed on both sides of the compression ring 31. Limiting grooves 3111 matching the limiting blocks 14 are formed along the length direction on the limiting plates 311, allowing the limiting blocks 14 and the limiting grooves 3111 to slide together. The limiting blocks 14 and the limiting grooves 3111 prevent the compression ring 31 from tilting during movement. Furthermore, when the operator moves the compression ring 31 via the connecting rod 32, and the compression ring 31 moves the drainage pipe 1, it facilitates the movement of the drainage pipe 1, preventing instability caused by the compression ring 31 rotating on the drainage pipe 1.

[0047] For further details, please refer to Figure 3 and Figure 4 A positioning plate 3112 is hinged to one end of the limiting plate 311 near the compression ring 31, and the positioning plate 3112 and the limiting plate 311 are arranged perpendicularly to each other. A notch matching the limiting block 14 is provided on the positioning plate 3112, so that when the operator moves the compression ring 31 to its furthest distance from the second sealing ring 22, rotating the positioning plate 3112 will cause the limiting block 14 to engage in the notch, thus preventing the compression ring 31 from moving further. At this time, when the operator moves the drainage pipe 1 via the connecting rod 32, there will be no relative movement or rotation between the compression ring 31 and the drainage pipe 1, allowing for better adjustment of the position of the drainage pipe 1.

[0048] For further details, please refer to... Figure 3 and Figure 4A magnet 31121 is fixedly mounted on the positioning plate 3112. The limiting plate 311 is made of iron that can attract the magnet 31121, and is coated with anti-rust paint to protect it. When the notch and the limiting block 14 are engaged, the magnet 31121 and the limiting plate 311 are attracted to each other, which improves the firmness of the positioning plate 3112.

[0049] This application also discloses a method for installing a sewage drainage pipe, including the following steps:

[0050] Step 1: Use a crane to lift the drainage pipe 1 to be installed. Clean the socket 12 and spigot 13 of the two drainage pipes 1 to be connected, and then apply a non-corrosive lubricant to the socket 12 and spigot 13. Flip open the flange 224 of the second sealing ring 22 and inject sealant into the cavity 221 through the injection hole 223. After filling, flip the flange 224 so that the plug 2241 seals the injection hole 223. Then, put the second sealing ring 22 on the spigot 13 so that the flange 224 is engaged in the positioning groove 131. Then, put the first sealing ring 21 on the spigot 13 so that the first sealing ring 21 is engaged in the sealing groove.

[0051] Step 2: Move the compression ring 31 to its furthest point from the second sealing ring 22, and rotate the positioning plate 3112 so that the notch engages with the limiting block 14. The operator adjusts the position of the drainage pipe 1 lifted by the crane using the connecting rod 32, so that the connecting rod 32 is inserted into the connecting pipe 34 on the other drainage pipe 1, thereby achieving the alignment connection between the spigot 13 and the socket 12. Move the drainage pipe 1 so that the second sealing ring 22 abuts against the other drainage pipe 1.

[0052] Step 3: Flip the positioning plate 3112 to disengage it from the limiting block 14. Move the compression ring 31 so that it abuts against the second sealing ring 22. Install the nut 33 on the connecting rod 32 and continuously rotate the nut 33, causing the compression ring 31 to continuously move towards the second sealing ring 22, thereby squeezing the sealant inside the second sealing ring 22 into the gap between the socket portion 13 and the receiving portion 12, and filling the gap.

[0053] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
