Description

Technical Field

[0001] This invention relates to the field of drainage pipe technology, specifically to a composite drainage pipe and its laying process. Background Technology

[0002] Drainage pipes refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. With the advancement of urbanization, urban drainage pipes also need to be upgraded in line with the pace of urbanization. Their main functions are to treat domestic sewage and clean and prevent flooding of urban streets. However, since domestic sewage and rainwater flowing through urban streets carry some debris, and in order to maintain the aesthetics of the urban environment, the pipes used in urban drainage systems are usually selected with relatively small diameters, which can easily lead to blockages.

[0003] Existing drainage pipes typically trap debris from sewage onto the street surface using filters at the pipe openings. While increasing the diameter of drainage pipe openings at street locations can alleviate the problem of debris clogging pipes to some extent, it requires regular cleaning by sanitation workers and is not very convenient to use. Especially in sparsely populated streets, it can easily lead to excessive accumulation of debris at the pipe openings, thus affecting drainage efficiency. Therefore, this invention proposes a composite drainage pipe and its laying process. Summary of the Invention

[0004] To address one of the shortcomings of existing technologies, this invention provides a composite drainage pipe that solves the problem of cleaning filtered materials in drainage pipes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite drainage pipe, comprising: The main pipe, which is the tubular main body of this drainage pipeline, includes: The first chamber is a through chamber opened along the axial direction of the main pipe. Taking the usage state of this drainage pipe as a reference, the upper end of the first chamber is the main inlet of the main pipe, and the lower end is the main outlet of the main pipe. The second chamber is located on the side of the first chamber and is connected to the first chamber. The drain outlet is located on the wall of the main pipe and connects to the second chamber; this drainage pipe also includes: A filtration mechanism is disposed in the first chamber, and the filtration mechanism includes an inclined filter plate; the lower horizontal end of the filter plate is disposed towards the second chamber.

[0007] Preferably, the filter mechanism is slidably connected to the first chamber, and the filter mechanism can rise or fall along the axis of the first chamber; according to the filter mechanism's own movement path, the working state of this drainage pipe includes: State 1: The filter mechanism is in a high horizontal position, the first partition component is in the open state, and the second partition component is in the closed state. State 2: The filter mechanism is in a low horizontal position, the first partition component is in a closed state, and the second partition component is in an open state. The filtering mechanism is linked to the first partition component and the second partition component respectively. The sliding of the filtering mechanism in the first chamber can link the first partition component and the second partition component to present the corresponding working state in state one or state two.

[0008] Preferably, the first chamber includes: The rectangular cavity portion, in which both the filter mechanism and the first partition assembly are disposed; The second chamber is an annular chamber, and a chamber channel connecting the two chambers is provided on the wall between the second chamber and the first chamber.

[0009] Preferably, the filtration mechanism further includes: The filter plate frame is vertically and slidably connected to the rectangular cavity, and the filter plate is fixedly connected to the filter plate frame. The filter plates are arranged symmetrically with the central axis of the filter plate frame as the center line. The end of the two filter plates away from the central axis of the filter plate frame is the low horizontal end.

[0010] Preferably, the first partition assembly includes: Two first partition plates are arranged opposite each other inside the rectangular cavity. The sides of the two first partition plates that are far apart from each other are rotatably connected to the sidewall of the rectangular cavity. In the first state, both first partition plates are in an inclined state. In the second state, both first partition plates are in a horizontal state, and their opposite edges are abutting each other. A groove is provided on the side wall of the rectangular cavity, and the groove is located near the edge where the first partition plate pivot is located; the upper end and the lower end of the groove extend to the upper and lower sides of the edge of the first partition plate, respectively. The filtration mechanism also includes: The first linkage component includes a first linkage member corresponding to each of the first partition plates. The first linkage member is disposed between the upper part of the filter plate frame and the lower side of the first partition plate. The filter plate frame can drive the first partition plate to rotate through the first linkage member.

[0011] Preferably, the first chamber has symmetrically formed chamber channels on the two side walls corresponding to the filter plate, and the second partition assembly includes: The second partition plate consists of two pieces, each of which is vertically and slidably connected to one of the chamber passages; A connecting component is provided between the two second partition plates, and a lower magnet is provided on the connecting component; The filtration mechanism also includes: The second linkage component includes an upper magnet disposed on the filter plate frame. When the filtration mechanism is in state two, the upper magnet and the lower magnet attract each other.

[0012] Preferably, the filtration mechanism further includes: The limiting component is an elastic telescopic member installed on the side wall of the rectangular cavity. When the first partition plate is in state one as shown, the limiting component abuts against the lower edge of the first partition plate. The guiding structure includes: The main guide groove is formed on the side wall of the rectangular cavity and extends in the vertical direction. The filter plate frame is slidably connected to the main guide groove. A secondary guide groove, corresponding to the connecting component, guides the movement path of the connecting component; A reset component is provided at the pivot of the first partition plate for resetting the first partition plate.

[0013] Preferably, it also includes: Several secondary pipes are provided and connected sequentially to the outlet end of the main pipe; the secondary pipes are male and female plug-in pipes, and their two ends are respectively: The male connector is equipped with a plug-in part and a snap-fit ​​part; The female plug end has a slot structure corresponding to the plug-in part and a slot structure corresponding to the snap-fit ​​part; the snap-fit ​​part of the male plug end can engage with the slot structure of the female plug end.

[0014] A drainage pipe laying process, applied to the aforementioned composite drainage pipe, includes the following steps: S1. A trench is dug in the road surface to install this device, and then the top surface of the main pipe is flush with the ground and fixed to the side wall of the trench; a cleaning groove is reserved on the side of the trench where the main pipe is buried; S2. Arrange the secondary tubes in the groove according to the matching relationship between the male and female ends, and connect the secondary tube at one end to the lower end of the main tube. S3.

S4. Fix the secondary pipe and the trench to ensure that the connected secondary pipe can communicate with the sewage collection point. Reinforce the trench according to the standard. Finally, backfill the soil and level the road surface.

[0015] Compared with existing technologies, this solution has the following advantages: By installing a filtration mechanism inside the main pipe, this solution can trap the pollutants in urban sewage or street rainwater inside the main pipe and quantitatively transport them to the second chamber. This not only reduces the probability of blockage in the drainage pipe, but also prevents pollutants from accumulating at the pipe opening and affecting the city's image. It also reduces the frequency of sanitation workers cleaning the pipe, achieving multiple benefits.

[0016] The main body of this solution is also equipped with a partition mechanism. In conjunction with the partition mechanism, the water inlet of the main body can be blocked during the process of the filtration mechanism transporting debris to the second chamber, so as to prevent sewage from flowing into the second chamber and ensure that the storage capacity of the second chamber is not affected by the water flow.

[0017] The secondary pipe in this design features both a plug-in section and a snap-fit ​​section. This ensures quick and easy connection of the secondary pipe, while the snap-fit ​​section and groove structure create a labyrinthine sealing structure, enhancing the sealing effect. This simplifies pipe laying for workers and guarantees the seal between adjacent pipe sections. Attached Figure Description

[0020] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 and Figure 2 This application provides the following technical solutions: A composite drainage pipe includes a main pipe 1, which serves as a vertical inlet pipe for the drainage system, and the main pipe 1 is the water inlet pipe at the ground surface. A top cover 14 is provided at the top of the main pipe 1, and the top cover 14 can be selected from suitable cover plates according to the actual needs of the construction location.

[0022] The main pipe 1 has a first chamber 11 and a second chamber 12. The first chamber 11 is a through cavity opened along the axial direction of the main pipe 1. Referring to the usage state of this drainage pipe, the upper end of the first chamber 11 is the main inlet of the main pipe 1, i.e., the inlet end equipped with the top cover 14, and the lower end is the main outlet of the main pipe 1; the outlet connects to the underground drainage pipe. The second chamber 12 is located on the side of the first chamber 11 and is connected to the first chamber 11. A drain outlet 13 is opened on the pipe wall of the main pipe 1, and the drain outlet 13 is connected to the second chamber 12. This drainage pipe also includes a filter mechanism 2, which is located inside the first chamber 11. The filter mechanism 2 includes an inclined filter plate 21; the lower horizontal end of the filter plate 21 faces the second chamber 12.

[0023] When the drainage pipe of this scheme is in use, the sewage enters the first chamber 11 from the top cover 14 of the main pipe 1. During the process of passing through the filter mechanism 2, the filter plate 21 intercepts larger debris in the sewage. Then, it enters the second chamber 12 along the inclined plate of the filter plate 21 and is discharged from the drain outlet 13.

[0024] Based on the above implementation plan, see Figure 2 and Figure 3 A partition mechanism 3 is also provided inside the main pipe body 1. The partition mechanism 3 is used to block the water passage inside the main pipe body 1. The partition mechanism 3 includes a first partition component 31 and a second partition component 32. The first partition component 31 is located below the main water inlet and can block the water inlet at the main water inlet. The second partition component 32 is located between the first chamber 11 and the second chamber 12 and can block the passage between the first chamber 11 and the second chamber 12. A third partition component is provided at the sewage outlet 13 and can isolate the sewage outlet 13 from the external space.

[0025] The following solutions can be adopted for the structural design of sewage outlet 13: First, a dedicated sewage pipe can be connected to the outside of sewage outlet 13, and debris can be discharged through a pump or auger-type device that can apply active sewage discharge force. Second, as shown in the appendix to this solution... Figure 1 As shown, a separate sewage door is installed at sewage outlet 13. During construction, a groove is reserved on the ground surface at the location of the sewage door so that it can be opened. When sewage needs to be discharged, workers can open the sewage door through the groove on the ground surface to remove and clean the debris inside. The third partition component can adopt different structures for these two forms. In the first form, the third partition component can be equipped with a valve structure; in the second form, the third partition component is the sewage door itself.

[0026] Considering the need to clean the dirt in the second chamber 12, a first partition assembly 31 and a second partition assembly 32 are provided. During normal use, water will not enter the second chamber 12. In this state, dirt in the second chamber 12 can be removed through the drain port 13, while water from above will not enter the second chamber 12. When the dirt on the filter plate 21 accumulates to a certain weight, the first partition assembly 31 can block the water inlet to the first chamber 11. At this time, the second partition assembly 32 is released from blocking the second chamber 12, allowing the dirt on the filter plate 21 to enter the second chamber 12. Since no water enters the main pipe 1 at this time, sewage can be prevented from directly entering the second chamber 12.

[0027] Based on the above implementation scheme, the filter mechanism 2 is slidably connected to the first chamber 11, and the filter mechanism 2 can rise or fall along the axis of the first chamber 11; the filter mechanism 2 is linked with the first partition assembly 31 and the second partition assembly 32 respectively, and the working state of the aforementioned drainage pipe is divided into the following according to the movement path of the filter mechanism 2: In state one, the filter mechanism 2 is in a high horizontal position, the first partition component 31 is in the open state, and the second partition component 32 is in the closed state. State 2: The filter mechanism 2 is in a low horizontal position, the first partition component 31 is in a closed state, and the second partition component 32 is in an open state. By sliding the filter mechanism 2 within the first chamber 11, the first partition assembly 31 and the second partition assembly 32 are respectively in the corresponding working states of state one or state two.

[0028] In this design, the lifting and lowering of the filter mechanism 2 serves as the triggering mechanism for the first and second partition components 31 and 32 in the partition mechanism 3. The movement of a single mechanism drives the coordinated action of the two partition components in different positions, thus achieving a perfect combination of the two working states for opening and closing the water passage. The filter mechanism 2 adopts a structure that can be lifted and lowered within the first chamber 11, achieving linkage through simple lifting and lowering movements, greatly reducing the overall structural complexity and providing greater controllability.

[0029] Based on the above implementation plan, see Figure 2 The first chamber 11 includes a rectangular cavity 111, within which the filter mechanism 2 and the first partition assembly 31 are both housed. Because this design requires the first partition assembly 31 to seal the entire main pipe 1 from water inlet, and also needs to consider the linkage between the filter mechanism 2 and the first partition assembly 31, the first partition assembly 31 is a rectangular plate, and the first chamber 11 is correspondingly equipped with the rectangular cavity 111 to achieve a better water inlet sealing effect. The second chamber 12 is an annular chamber, such as... Figure 3As shown, a chamber passage 113 communicating the second chamber 12 and the first chamber 11 is provided on the cavity wall therebetween, and the chamber passage 113 is located below the filter plate 21. Compared with the rectangular cavity portion 111 in the first chamber 11, the specific structural shape of the second chamber 12 does not require high requirements. When the rectangular cavity portion 111 itself is a rectangular cavity, it is sufficient to provide the chamber passage 113 on two parallel side walls thereof. In order to facilitate dirt to converge to the position of the sewage outlet 13, the bottom surface of the second chamber 12 can be provided as an inclined surface, so that the bottom surface of the second chamber 12 is inclined downward toward the sewage outlet 13.

[0030] Based on the above embodiment, refer to Figures 2-4 and Figure 8 , the filter mechanism 2 further comprises a filter plate holder 22, the filter plate holder 22 is vertically slidably connected with the rectangular cavity portion 111, and the filter plate 21 is fixedly connected with the filter plate holder 22; two filter plates 21 are symmetrically arranged with the central axis of the filter plate holder 22 as the center line, and the ends of the two filter plates 21 away from the central axis of the filter plate holder 22 are low-level ends.

[0031] The filter plate holder 22 has an overall inverted T-shaped structure, a vertical middle plate 221 is provided at the middle position of the lower part of the filter plate holder 22, the filter plates 21 are respectively located on both sides of the middle plate 221. The structure of the middle plate 221 facilitates the installation of the filter plates 21. With the middle plate 221 serving as a connecting carrier for the filter plates 21, the filter plates 21 can be fixed on the middle plate 221 by means of plug-in connection, which is more convenient and faster when the filter plates 21 need to be replaced during use.

[0032] Vertical plates 222 are provided on the other two sides of the middle plate 221, the middle plate 221 is fixedly connected between the lower parts of the vertical plates 222, and a linkage frame 223 is provided between the upper parts of the vertical plates 222. The linkage frame 223 serves as the linkage structure of the first partition assembly 31, and the linkage frame 223 can be configured as a hollow frame. The linkage frame 223 in the present solution adopts a structure of two parallel rods.

[0033] Based on the above embodiment, refer to Figure 8 , the first partition assembly 31 comprises two first partition plates 311, the two first partition plates 311 are oppositely arranged on the inner side of the rectangular cavity portion 111, and the sides of the two first partition plates 311 away from each other are rotatably connected with the side wall of the rectangular cavity portion 111 through a first rotating shaft 312; in a first state, both of the two first partition plates 311 are in an inclined state; in a second state, both of the two first partition plates 311 are in a horizontal state, and the opposite side edges of the two first partition plates 311 are attached to each other.

[0034] A groove 112 is formed on the side wall of the rectangular cavity 111, and the groove 112 is located near the edge where the first rotating shaft 312 is located; the upper end and lower end of the groove 112 extend to the upper and lower sides of the edge of the first partition plate 311, respectively. When the first partition plate 311 is in an inclined state, that is, the state one mentioned above, the water flowing into the upper part of the main pipe 1 can pass between the two first partition plates 311, or flow downward at the groove 112. When the first partition plate 311 is in a horizontal state, that is, the state two mentioned above, the two first partition plates 311 are side by side and close each other, and each closes its corresponding groove 112. At this time, the water flowing above cannot flow down through the first partition plate 311.

[0035] The filtration mechanism 2 also includes a first linkage assembly 23, which includes a first linkage member corresponding to each first partition plate 311. The first linkage member is disposed between the upper part of the filter plate frame 22 and the lower side of the first partition plate 311. The filter plate frame 22 can drive the first partition plate 311 to rotate through the first linkage member. The first linkage member can be a flexible member or a rigid member, with a rigid member being preferred, such as... Figure 8 As shown, the first linkage component of this scheme is a short connecting rod. Two short connecting rods are provided for each first partition plate 311. One end of the short connecting rod is rotatably connected to the lower side of the first partition plate 311, and the other end is rotatably connected to the frame of the linkage frame 223.

[0036] A reset member 33 is also provided on the first rotating shaft 312. The reset member 33 is used to reset the first partition plate 311. In this scheme, the reset member 33 can be a torsion spring.

[0037] With the structure of this solution, under normal working conditions, the internal structure of the main body 1 presents... Figure 2 The state shown. When the amount of dirt left on the filter plate 21 reaches a certain weight, the filter plate 21 moves downward, thereby driving the first partition plate 311 to enter state two through the first linkage composed of short connecting rods, which is to close the water inlet end of the main pipe 1.

[0038] For this structure, this solution also proposes an implementation where feedback devices, such as proximity switches or contact switches, are incorporated into the displacement of the filter plate holder 22. When the filter plate holder 22 moves down to a certain position, the main body 1 at that position is closed. Feedback is sent to the host computer system through the feedback devices, thereby informing the personnel responsible for the corresponding area to clean the dirt. At the same time, the second partition assembly 32 releases the closure of the chamber channel 113, allowing dirt on the filter plate 21 to enter the second chamber 12.

[0039] Based on the above implementation scheme, the previous implementation scheme has a problem: as the dirt on the filter plate 21 increases, the filter plate holder 22 may gradually move downwards. This causes the first partition component 31 to not completely seal the water inlet, but rather reduces the water inlet space, which affects the use of the drain pipe. In view of this problem, the filter mechanism 2 is also provided with a limit component 25, see [link to relevant documentation]. Figure 7 The limiting component 25 is an elastic telescopic member disposed on the side wall of the rectangular cavity 111. When the first partition plate 311 is in the state shown, the limiting component 25 abuts against the lower edge of the first partition plate 311.

[0040] The limiting component 25 can be configured as a hemispherical block combined with a spring on the side wall of the rectangular cavity 111. Correspondingly, a notch 313 is provided on the lower side of the first partition plate 311. The notch 313 is concave upwards, and the recessed area is an arc-shaped surface. With this structure, in state one, in addition to the force of the reset member 33 itself, the limiting component 25 acts as the limiter of the first partition plate 311. When the weight of the dirt on the filter plate 21 reaches a certain weight, the filter plate frame 22 will pull the first partition plate 311 to squeeze the hemispherical block of the limiting component 25 into the side wall of the rectangular cavity 111, and then the first partition plate 311 will switch to state two. After the dirt on the filter plate 21 is removed, the reset member 33 drives the first partition plate 311 to reset. During the reset process, the limiting component 25 is squeezed into the side wall again. When the first partition plate 311 rotates upward beyond the position of the limiting component 25, the hemispherical block is pushed out by its spring and stuck in the notch 313 until the dirt on the filter plate 21 exceeds its weight capacity again, and the above process is repeated.

[0041] Based on the above implementation plan, see Figures 3 to 6The first chamber 11 has symmetrical chamber channels 113 on two side walls corresponding to the lower edge of the filter plate 21. The second partition assembly 32 includes two second partition plates 321, each of which is vertically slidably connected to a chamber channel 113. A connecting assembly 322 spans between the two second partition plates 321, and a lower magnet 323 is provided on the connecting assembly 322. The connecting assembly 322 and the second partition plate 321 form a rectangular frame structure, and the lower magnet 323 is located in the middle of the connecting assembly 322. In state one, the second partition plate 321 closes the chamber channel 113 it is in. In state two, the connecting assembly 322 moves the second partition plate 321 upward, and the chamber channel 113 opens. This is the implementation form of the second partition assembly 32 adopted in this solution, in order to realize the linkage between the filter plate frame 22 and the second partition plate 321. The filtration mechanism 2 also includes a second linkage component 24, which includes an upper magnet 243 mounted on the filter plate holder 22. When the filtration mechanism 2 is in state two, the filter plate holder 22 moves downward, causing the upper magnet 243 to move above the lower magnet 323. The upper magnet 243 attracts the lower magnet 323 upward, thereby lifting the second partition plate 321 upward and opening the chamber channel 113. At this time, the lower edge of the filter plate 21 moves to the position of the chamber channel 113. Because the chamber channel 113 is open, dirt on the filter plate 21 can enter the second chamber 12.

[0042] This solution removes contaminants from the internal filter structure of drainage pipes without using electronically controlled components. Because of the specific working environment of this solution, the lifespan of electronically controlled components would be significantly affected; therefore, the mechanically linked structure of this solution is better suited to the operational requirements of drainage pipes.

[0043] Based on the above implementation plan, see Figures 6-8 A guide structure 26 is also provided on the side wall of the rectangular cavity 111. The guide structure 26 includes a main guide groove 261 and a secondary guide groove 262. The main guide groove 261 extends vertically, and the upright plate 222 of the filter plate holder 22 is slidably connected to the main guide groove 261. The secondary guide groove 262 is provided corresponding to the connecting assembly 322 to guide the movement path of the connecting assembly 322.

[0044] like Figure 6As shown, the connecting component 322 adopts a structure that forms a rectangular frame with the second partition plate 321. The secondary guide groove 262 forms a slot structure surrounding the side wall of the rectangular cavity 111. In other words, the connecting component 322 is located outside the filter plate frame 22, therefore, the secondary guide groove 262 is located outside the main guide groove 261. Because this solution is applied to drainage pipes, considering that dirt may affect the movement of the structural mechanism, both the main guide groove 261 and the secondary guide groove 262 are set on the side wall to minimize the possibility of being affected during use.

[0045] Based on the above implementation plan, see Figure 6 and Figure 8 The second linkage component 24 is a telescopic structure. A horizontal groove 242 is provided on the vertical plate 222. The slider 241 is slidably connected in the groove 242. The upper magnet 243 is fixedly connected to the slider 241. A spring is provided between the slider 241 and the groove 242. This structure enables the upper magnet 243 to have elastic telescopic function.

[0046] Corresponding to this structure of the upper magnet 243, a transition groove 263 is provided between the main guide groove 261 and the secondary guide groove 262 of the guide structure 26. The upper magnet 243 slides vertically in the transition groove 263. The upper ends of the transition groove 263 and the secondary guide groove 262 are connected, and an inclined surface is provided at the position of the groove where the two are connected. When the filter plate frame 22 moves down, the upper magnet 243 moves to the bottom of the transition groove 263. Under the action of its own spring, it pushes out towards the position above the secondary guide groove 262. At this time, it can attract the lower magnet 323 in the secondary guide groove 262 upward, thereby causing the second partition plate 321 to move upward. When the dirt on the filter plate 21 slides into the second chamber 12, because the weight of the filter plate frame 22 decreases, the first partition plate 311 rotates under the action of the reset member 33, pulling the filter plate frame 22 upward. At this time, the upper magnet 243 performs an upward movement path along the inclined structure of the transition groove 263. This movement makes it easier for it to detach from the lower magnet 323.

[0047] Based on the above implementation scheme, several secondary pipes 4 are connected sequentially to the outlet end of the main pipe 1. The secondary pipes 4 can be made into bends or straight pipes according to actual needs. Each secondary pipe 4 is a male-female plug-in pipe, with a male plug end 41 and a female plug end 42 at its two ends.

[0048] The male plug end 41 is provided with a plug-in part and a snap-fit ​​part; the female plug end 42 is provided with a slot structure corresponding to the plug-in part and a slot structure corresponding to the snap-fit ​​part; the snap-fit ​​part of the male plug end 41 can be engaged with the slot structure of the female plug end 42.

[0049] See Figure 9 and Figure 10The male connector 41 has a snap-fit ​​portion including an annular boss 412 with several snap-fit ​​blocks arranged circumferentially on the annular boss 412. The female connector 42 has an annular groove structure with several snap-fit ​​slots corresponding to the snap-fit ​​blocks in the groove. This snap-fit ​​portion design allows two adjacent secondary tubes 4 to be connected at a fixed angle, thereby ensuring the alignment of the connector's own insertion structure.

[0050] The male connector 41 has a plurality of insert plates 411. One end of each insert plate 411 is rotatably connected to the inner wall of the male connector 41, and the other end is provided with a wedge with an inclined surface. A torsion spring is provided at the connection between the insert plate 411 and the inner wall of the male connector 41. The female connector 42 has a slot 421 corresponding to the wedge of the insert plate 411. A plurality of insert plates 411 and slots 421 are arranged in a circumferential array.

[0051] Based on this structure, this solution proposes a drainage pipe laying process, including the following steps: S1. A trench is opened on the road surface to install this device, and then the top surface of the main pipe 1 is flush with the ground and fixed to the side wall of the trench; a cleaning groove is reserved on the side of the trench where the main pipe 1 is buried; the cleaning groove is set to correspond to the sewage outlet 13 to facilitate subsequent cleaning.

[0052] S2. Based on the mating relationship between the male end 41 and the female end 42, the secondary tube 4 is arranged in the groove, and one end of the secondary tube 4 is connected to the lower end of the main tube 1.

[0053] S3. Align the snap-fit ​​parts and slot structures of the remaining sub-tube bodies 4, adjust the positions of all sub-tube bodies 4, and insert the tube bodies of the sub-tube bodies 4 one by one to complete the connection and locking of each sub-tube body 4. In this process, first use the snap-fit ​​parts to determine the alignment direction of the sub-tube bodies 4 so that their insert plates 411 and slots 421 will not be misaligned during subsequent insertion. As two adjacent sub-tube bodies 4 approach each other, the insert plate 411 will slightly twist when it contacts the female insert end 42. After the wedge of the insert plate 411 reaches the position of the slot 421, the wedge enters the slot 421 under the action of the torsion spring, thus completing a firm insertion. In addition, a sealing gasket or glue needs to be set at the connection between the male insert end 41 and the female insert end 42. This is existing technology and will not be described in detail.

[0054] S4. Fix the secondary pipe 4 and the trench to ensure that the connected secondary pipe 4 can communicate with the sewage collection point. Reinforce the trench according to the standard. Finally, backfill the soil and level the road surface to complete the construction.

[0055] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
