[0002] For urban drainage systems, within a certain area, the main sewage pipes are generally buried deeper and the main rainwater pipes are buried shallower. When it is necessary to intercept the combined sewer pipes of upstream plots, interception wells are usually set up to intercept and discharge the wastewater. When existing urban drainage systems have downstream sewage main pipes at higher elevations than stormwater main pipes (i.e., sewage main pipes are buried shallower while stormwater main pipes are buried deeper), and upstream areas with combined sewer systems are difficult to effectively intercept and divert, especially in older residential areas, construction costs are high, and effective interception operations during rainy and dry weather are impossible, affecting the convenience of direct interception and discharge in well chambers during rainy and dry weather. To address this, this utility model proposes a double-layer interception well chamber structure. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figures 1 to 4 This utility model provides a technical solution: a double-layer interception well chamber structure, including a second-layer base plate 101, the second-layer base plate 101 is a rectangular structure, the upper surface of the second-layer base plate 101 is provided with a double-layer interception and drainage mechanism, the double-layer interception and drainage mechanism includes a water inlet component provided on the upper surface of the second-layer base plate 101, the top of the inside of the water inlet component is provided with an interception component, and the bottom side of the inside of the water inlet component is provided with a rainwater discharge component.
[0015] In order to facilitate the interception and treatment of water inlet through the water inlet assembly, in this embodiment, preferably, the water inlet assembly includes a well wall 1011 formed by concrete casting on the upper surface of the second-floor base 101. A merging pipe 1014 is fixed on one side of the well wall 1011, which can enter the sewage or the rainwater and sewage chamber into the interior of the well wall 1011, facilitating the interception and treatment of water in the inner second floor.
[0016] To facilitate the interception and discharge of large amounts of rainwater and sewage through the interception assembly, in this embodiment, preferably, the interception assembly includes a base plate 1016 cast in concrete on one side of the top of the inner wall 1011. An overflow weir 1015 is cast on one side of the base plate 1016. An interception pipe 1013 is fixed to the front surface of the base plate 101. During dry weather, sewage can directly enter the inner first-level well chamber through the confluence pipe 1014 and be discharged into the downstream sewage pipe through the interception pipe 1013. During rainy weather, the rainwater and sewage discharge... When there is a large amount of wastewater, some of it is discharged through the interceptor pipe 1013, and some overflows through the overflow weir 1015 into the second-level well chamber and is discharged through 1012. The overflow weir 1015, the first-level bottom plate 1016 and the well wall 1011 form a first-level well chamber. The lower surface of the first-level bottom plate 1016 is located at the bottom of the well wall 1011, forming a second-level well chamber. The interceptor pipe 1013 and the confluence pipe 1014 are connected to the interior of the first-level well chamber, which can form a first-level well chamber and a second-level well chamber inside the well wall 1011, facilitating the interception and discharge of sewage and rainwater.
[0017] In order to facilitate the discharge of overflowing rainwater and sewage to the bottom through the rainwater drainage component, in this embodiment, preferably, the rainwater drainage component includes a rainwater pipe 1012 disposed at the bottom of the other side of the well wall 1011, and the end of the rainwater pipe 1012 is connected to the second-floor well chamber, so that the rainwater and sewage overflowing from the top of the well wall 1011 can be discharged to the outside through the rainwater pipe 1012 after entering the second-floor well chamber inside the second-floor base 101.
[0018] The end of the inlet component is equipped with a filter mechanism, which includes a fixed installation component installed at the end of the combined pipe 1014. The fixed installation component is equipped with a filter collection component inside. During the treatment of rainwater and sewage, the sewage is filtered by the filter mechanism before entering and being discharged from the combined pipe 1014, and then discharged into the well wall 1011 for treatment, which is less likely to cause blockage.
[0019] In order to facilitate the fixed installation and filtration of the collection box 1022 by means of a fixed installation assembly, in this embodiment, preferably, the fixed installation assembly includes a mounting box 102 fixed to the end of the confluence pipe 1014. The outer surface of the mounting box 102 is provided with an inlet pipe, so that the collection box 1022 can be fixedly installed inside the mounting box 102, which facilitates filtration and collection.
[0020] To facilitate filtration of rainwater and sewage before they enter the system, in this embodiment, preferably, the filtration and collection assembly includes a collection box 1022 enclosed inside the installation box 102. A limiting top plate 1021 is integrally provided at the top of the collection box 1022, and the limiting top plate 1021 is fixed to the top of the installation box 102 by bolts. A filter screen 1023 is provided on the inner surface of the collection box 1022. Interception rods 1024 are equidistantly fixed at the middle position of the collection box 1022. During use, the limiting top plate 1021 can limit and close the collection box 1022 inside the installation box 102 and fix it in place. When rainwater and sewage enter, the interception rods 1024 can intercept large impurities, while the filter screen 1023 can filter small impurities, facilitating the filtration process before it enters the interior and preventing blockage of the manhole wall 1011.
[0021] In this utility model, the merging pipe 1014, the intercepting pipe 1013, and the rainwater pipe 1012 can be made of reinforced concrete pipe, chemical pipe or steel pipe.
[0022] The working principle and usage process of this utility model: In the use of this double-layer interception well chamber structure, the second-layer bottom plate 101, well wall 1011, overflow weir 1015 and the first-layer bottom plate 1016 are all wrapped with steel bars before pouring, and then concrete is poured to form the structure. When used in dry weather, sewage normally enters the interior of the external sewage pipe into the confluence pipe 1014, and the sewage is intercepted in the well wall 1011 through the first-layer well chamber formed between the overflow weir 1015, the first-layer bottom plate 1016 and the well wall 1011. After interception, the sewage is discharged into the downstream sewage pipe through the interception pipe 1013. Then, when used in rainy weather, the combined sewer 1014 in the upstream plot has a large combined flow of rainwater and sewage, and the interceptor pipe 1013 alone cannot meet the drainage demand. At this time, the rainwater and sewage entering through the combined sewer 1014 enter the well wall 1011 and are intercepted by the overflow weir 1015, the first-floor slab 1016 and the first-floor well chamber formed between the well wall 1011. Part of the water is discharged to the downstream through the interceptor pipe 1013, and part of the water overflows from the overflow weir 1015 to the second-floor well chamber at the bottom of the well wall 1011 and is discharged to the downstream rainwater pipe through the rainwater pipe 1012, thus meeting the drainage demand in rainy weather. The interception structure is simple, the interception speed is fast, it is economical and convenient, and it has almost no impact on the production and life of the intercepted plot. The interception effect is good, effectively reducing the impact of the combined sewer on the urban water environment and improving the convenience of direct interception and discharge of the well chamber in rainy and dry weather. During drainage treatment, the collection box 1022 is engaged inside the installation box 102 at the end of the combined pipe 1014, and the limiting top plate 1021 is fixed to the top of the installation box 102 by bolts. After fixed installation, rainwater and sewage pass through the installation box 102 before entering the combined pipe 1014. Inside the installation box 102, large impurities are intercepted by the interception rod 1024, and small impurities are filtered by the filter screen 1023. This facilitates interception and filtration when rainwater and sewage enter. The filtered impurities are collected inside the collection box 1022, which is less likely to cause blockage or overflow. This facilitates effective interception and improves the convenience of the well chamber in preventing blockage of rainwater and sewage before interception in rainy and dry weather. When a large amount of impurities are collected, the limiting top plate 1021 and the collection box 1022 can be disassembled and cleaned periodically.
