[0022] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Example

[0024] Please see Figures 1 to 4As shown, the embodiment provides an inspection well 1 for drainage main pipe turning and branch pipe beveling, the drainage main pipe includes an upstream main pipe 2 and a downstream main pipe 3, and a branch pipe 4 is arranged above the drainage main pipe. The inspection well 1 for drainage main pipe turning and branch pipe beveling includes a well chamber 11 and a partition wall 12. The well chamber 11 is annular in cross section and extends along a vertical direction 19. The partition wall 12 is arranged in the well chamber 11 and is connected with the well chamber 11 and separates the well chamber 11 into an energy dissipation well chamber 13 and an inspection well chamber 14. The bottom of the partition wall 12 is provided with a flow hole 121 which communicates the energy dissipation well chamber 13 and the inspection well chamber 14. The upstream main pipe 2 is arranged on the side of the well chamber 11 close to the inspection well chamber 14 and communicates with the inspection well chamber 14. The branch pipe 4 and the downstream main pipe 3 are arranged on the side of the well chamber 11 close to the energy dissipation well chamber 13 and communicate with the energy dissipation well chamber 13. The water flow in the upstream main pipe 2 and the water flow in the branch pipe 4 flow into the downstream main pipe 3 respectively.

[0025] The drainage main pipe turns at the position of the inspection well. The extension direction of the upstream main pipe 2 is arranged at an angle with the extension direction of the downstream main pipe 3. The extension direction of the branch pipe 4 is arranged at an angle with the extension direction of the downstream main pipe 3. The inspection well 1 for drainage main pipe turning and branch pipe beveling provided by the embodiment communicates the pipes with different extension angles through the annular well chamber 11, the partition wall 12 connected with the well chamber 11 and separating the well chamber 11 into the energy dissipation well chamber 13 and the inspection well chamber 14, the upstream main pipe 2 communicating with the inspection well chamber 14, and the branch pipe 4 and the downstream main pipe 3 communicating with the energy dissipation well chamber 13, so as to achieve the effect that the inspection well is adapted to the pipe access with multiple angles.

[0026] In the embodiment, the upstream main pipe 2, the downstream main pipe 3 and the branch pipe 4 are arranged in the circumferential direction of the well chamber 11. The upstream main pipe 2 is connected with the side wall of the well chamber 11 close to the inspection well chamber 14. The downstream main pipe 3 and the branch pipe 4 are connected with the side wall of the well chamber 11 close to the energy dissipation well chamber 13. Such arrangement makes the inspection well 1 for drainage main pipe turning and branch pipe beveling adapted to the pipe access with multiple angles.

[0027] The inspection well 1 for drainage main pipe turning and branch pipe beveling further includes a first waterproof sleeve 21, a second waterproof sleeve 31 and a third waterproof sleeve 41. The upstream main pipe 2 and the well chamber 11 are connected through the first waterproof sleeve 21. The downstream main pipe 3 and the well chamber 11 are connected through the second waterproof sleeve 31. The branch pipe 4 and the well chamber 11 are connected through the third waterproof sleeve 41. Thus, the water flow in the upstream main pipe 2, the downstream main pipe 3 and the branch pipe 4 is reduced to leak to the outside of the well chamber 11, so as to make the inspection well 1 for drainage main pipe turning and branch pipe beveling adapted to the pipe access with multiple angles.

[0030] In the embodiment, the branch pipe 4 is located above the downstream main pipe 3, the first buffer plate 131 and the second buffer plate 132 are staggered and spaced apart between the branch pipe 4 and the downstream main pipe 3, respectively, the first buffer plate 131 and the second buffer plate 132 respectively block the water flow, and in the process of the water flow in the branch pipe 4 falling to the downstream main pipe 3, the water flow impacts downward to the first buffer plate 131 opposite to the branch pipe 4, and then the water flow rebounds from the first buffer plate 131 and impacts downward to the second buffer plate 132, and so on for several times to reduce the impact force of the water flow, so that the water flow in the branch pipe 4 flows into the downstream main pipe 3, thereby the inspection well is adapted to the pipe access of multiple angles. The number and position of the first buffer plate 131 and the second buffer plate 132 are flexibly arranged according to the water flow drop.

[0031] In a possible implementation, the inspection well 1 for the drainage main pipe turning and branch pipe beveling further comprises a top plate 16, a bottom plate 17 and an inspection shaft 15, the top plate 16 is arranged at the top of the well chamber 11 and fixedly connected with the well chamber 11, and the top plate 16 covers the top of the energy dissipation well chamber 13 and the top of the inspection well chamber 14.

[0034] In the embodiment, the inspection well 1 for the drainage main pipe bend and the branch pipe bevel joint further comprises a well chamber cushion layer 18 arranged on the bottom surface of the bottom plate 17. The buffer layer 133 comprises pebbles, and the buffer layer 133 is laid on the bottom plate 17 for further reducing the flow speed of the water flow in the branch pipe 4 flowing into the downstream main pipe 3, so that the inspection well is suitable for the pipe access of multiple angles.

[0040] In the embodiment, the air hole 123 is used to communicate the air flow in the inspection well chamber 14 and the energy dissipation well chamber 13, so that the air pressure in the inspection well chamber 14 and the energy dissipation well chamber 13 is stable, which is conducive to the water flow in the upstream main pipe 2 and the water flow in the branch pipe 4 flowing into the downstream main pipe 3.
