[0033] The specific settings and functions of the fixed structure 3 and the auxiliary structure 4 are described in detail below.

[0034] Reference Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment: the fixing structure 3 includes four connecting shafts 31, the lower end of the connecting shaft 31 is fixedly connected to the prefabricated foundation member 1, the upper end of the connecting shaft 31 is fixedly connected to a fixing ring 32, the lower end of the segmented pipeline 2 is provided with four positioning grooves 33, the arc surface of the segmented pipeline 2 is provided with a circular hole 34 near the positioning groove 33, and the fixing ring 32 is provided with a steel nail 35, which passes through the circular hole 34 and the inside of the fixing ring 32 in sequence, and one end thereof extends out of the segmented pipeline 2. By inserting the fixing ring 32 into the positioning groove 33 and inserting the steel nail 35 into the fixing ring 32 at the same time, the prefabricated foundation member 1 and the segmented pipeline 2 can be connected, and the steel nail 35 can be inserted into the backfill soil to fix the connection of the pipeline.

[0035] The inner wall of the circular hole 34 is fixedly connected with a sealing gasket 36, which is a rubber gasket. The sealing gasket 36 is used to seal the inside of the segmented pipe 2 after the steel nail 35 is fixed to prevent sewage leakage. A spiral pattern 37 is provided on the arc surface at one end of the steel nail 35, and one end of the steel nail 35 is in a pointed cone shape. After the spiral pattern 37 is inserted into the soil for fixing, it is used to increase friction and enhance the fixing strength of the steel nail 35.

[0036] Reference Figure 5 As shown, specifically, a plurality of steps 38 are fixedly connected to the inner wall of the segmented pipe 2, and the spacing between the steps 38 is equal. The steps 38 are used to facilitate workers to go down the well for maintenance or cleaning. An anti-blocking member 39 is fixedly connected to the inner wall of the segmented pipe 2, and the middle part of the anti-blocking member 39 is curved in an arc shape. The anti-blocking member 39 is used to intercept larger impurities in the sewage and make them entangled thereon. At the same time, its arc shape is curved to leave a certain space for workers to go down the well.

[0037] Reference Figure 6As shown, in this embodiment: the auxiliary structure 4 includes a fixed pipe 41, both ends of which are fixedly connected to the inner wall of the prefabricated foundation member 1, and two movable pipes 42 are rotatably connected inside the fixed pipe 41. Specifically, a cylindrical block is fixedly connected to one end of the movable pipe 42 close to the fixed pipe 41, and the cylindrical block is movably connected in the fixed pipe 41. The end of the movable pipe 42 away from the fixed pipe 41 is slidably inserted in the prefabricated foundation member 1. The horizontally and vertically crossed fixed pipes 41 and movable pipes 42 can block debris in the sewage, making it convenient for workers to clean up.

[0038] It should also be added that a sealing plugging shaft 43 is fixedly connected to one side of the arc surface of the movable tube 42, and a dredging plugging shaft 44 is fixedly connected to the side of the arc surface of the movable tube 42 away from the sealing plugging shaft 43. By setting the sealing plugging shaft 43 and the dredging plugging shaft 44, the blocking area is increased, and when there are many impurities in the sewage, it can be effectively blocked. The arc surface of the movable tube 42 is threadedly connected to two fixing nuts 45, and the two fixing nuts 45 are distributed at the upper and lower ends of the fixed tube 41. After the movable tube 42 is rotated to adjust the angle, the fixing nuts 45 located at the upper and lower ends of the fixed tube 41 can be rotated to make them abut against the cylindrical block up and down and clamped on the fixed tube 41, so that the movable tube 42 cannot be rotated and is fixed.

[0039] Working principle: when installing the combined sewage well, first put the prefabricated foundation member 1 into the base part and connect its two ends to the underground sewage pipe. Then install a segmented pipe 2 on the prefabricated foundation member 1. When the segmented pipe 2 moves downward for installation, insert the connecting shaft 31 and the fixing ring 32 inward into the positioning groove 33. Then, when backfilling the soil, insert the steel nail 35 into the circular hole 34. The steel nail 35 passes through the fixing ring 32 and passes through the segmented pipe 2. A sealing gasket 36 is provided in the circular hole 34. In order to prevent sewage leakage, the steel nails 35 are penetrated outward and nailed into the backfilled soil, so as to fix the connected segmented pipes 2, and circulate in sequence. After installing multiple segmented pipes 2, the installation of the combined sewage well can be completed, and steps 38 are provided in the segmented pipes 2 to facilitate workers to go down into the well for maintenance. At the same time, the anti-blocking parts 39 arranged in the segmented pipes 2 are used to block large debris in the sewage when the sewage falls, so that it is wrapped around the anti-blocking parts 39 to prevent large debris from falling to the bottom and clogging the sewage well.

[0040] By means of the auxiliary structure 4 arranged at the two ends at the bottom of the prefabricated foundation member 1, when there are many impurities in the sewage, the movable pipe 42 can be rotated to make the sealing plugging shaft 43 and the dredging plugging shaft 44 parallel to the pipe mouth, and at the same time, the fixing nut 45 is rotated to abut against the fixed pipe 41, so as to fix the movable pipe 42, thereby blocking a large amount of debris in the sewage, so as to facilitate later cleaning. Workers can directly clean the debris blocked on the sealing plugging shaft 43 and the dredging plugging shaft 44. At the same time, the movable pipe 42 can be rotated to make the sealing plugging shaft 43 and the dredging plugging shaft 44 rotate to a position perpendicular to the pipe mouth, which is suitable for when there are fewer debris in the sewage and can make the sewage pass more smoothly.
