Description

Technical Field

[0001] This application relates to the technical field of rainwater and sewage separation, and in particular to an integrated rainwater and sewage separation pipeline component. Background Technology

[0002] In the process of implementing rural sewage treatment projects, the traditional rainwater and sewage separation system adopts the mode of laying rainwater and sewage independently. During the implementation process, multiple sets of pipe networks are constructed in parallel, resulting in a disordered underground space layout and frequent pipe location conflicts. Especially in areas with narrow road cross-sections, pipelines are prone to cross-over and overlap, which greatly increases the construction difficulty and later maintenance costs. Furthermore, the construction of a separate rainwater and sewage separation system requires multiple excavations of pipe laying trenches, which not only damages the stability of the roadbed structure but also prolongs the construction period. In addition, due to the different materials of the separate pipe networks, the physical properties of the pipes differ (such as the coefficient of thermal expansion), causing stress concentration at the connection points, resulting in a high risk of leakage due to damage to the pipe network structure.

[0025] To facilitate understanding, the working principle of this application is further described as follows: First, a trench is pre-excavated using the trenching method. The bottom of the trench uses sand or soil as the foundation. The integrated rainwater and sewage diversion pipe component is hoisted and connected to the household connection pipes of each household through the connection drain pipe holes 13 on both sides, thereby effectively connecting sewage into the integrated rainwater and sewage diversion pipe component. The next integrated rainwater and sewage diversion pipe component is hoisted and a rubber ring is fitted to its end. Adjacent integrated rainwater and sewage diversion pipe components are connected end to end and sealed with flexible fillers such as hemp fiber. This achieves rapid connection and installation of the integrated rainwater and sewage diversion pipe components, effectively reducing the cross-section of the construction excavation and thus reducing construction costs. It should be noted that the pipe body 10 of the integrated rainwater and sewage separation pipe component is equipped with a snap-fit ​​component 21. The snap-fit ​​component 21 has a protrusion 22 at one end and a concave end 23 at the other end. The protrusion and concave end of the snap-fit ​​component 21 are matched to complete the assembly of adjacent integrated rainwater and sewage separation pipe components. Repeat the above process to lay multiple integrated rainwater and sewage separation pipe components until they are connected to the main sewage discharge outlet. Then, the cover plate 20 is placed directly above the pipe body 10. Finally, a water test is conducted to ensure that each integrated rainwater and sewage separation pipe component is leak-proof. The trench is then backfilled to ensure that the pipe body 10 is compacted. It should be noted that unused household drainage pipe holes 13 are sealed with concrete or corrosion-resistant rubber plugs to prevent groundwater from entering the interior of the pipe body 10. Unused water supply inlet pipe channels are also sealed with concrete or corrosion-resistant rubber plugs. Rainwater enters the rainwater flow channel 11 of the integrated rainwater and sewage diversion pipe component through the perforated cover plate 20. Sewage enters the sewage flow channel 12 through the pre-reserved household drainage pipe holes 13 on both sides of the component. When a water supply pipe needs to pass through the component, it can pass through the pre-reserved water supply inlet pipe channel 14, thus effectively solving the problem of frequent collisions and conflicts between the three sets of rainwater, sewage, and water supply pipe systems, as well as the problem of multiple trench excavations required for split construction, which leads to leakage at pipe joints and structural damage. After the entire system has been running for a period of time, the cover plate 20 at the top of the rainwater flow channel 11 can be opened to clean up the garbage and debris in the rainwater channel. After cleaning, the inspection door 16 at the bottom of the rainwater channel can be opened, and cleaning tools can be used to clean the bottom. The sewage overflow channel 12 of the part is cleaned to ensure smooth water flow and timely sewage flow, which effectively improves the convenience and efficiency of construction. It should be noted that L1, L2, L4, L5, and L6 are the lengths of the corresponding structural components, B1, B2, B3, B4, B5, and B6 are the widths of the corresponding structural components, H1 and H2 are the heights of the corresponding structural components, and T1, T2, T3, and T4 are the diameters of the corresponding structural components. The above dimensions need to be adjusted adaptively within the allowable range during actual installation.
