[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0017] According to the intercepting well of the embodiment of the present utility model, the intercepting well includes a well body 100, an inlet pipe 1, an overflow pipe 2, an outlet pipe 3 and a stopcock valve 8. A flow trough is provided at the bottom of the well body 100 to make the water flow smoothly in the well body. The inlet pipe 1 and the overflow pipe 2 are symmetrically arranged about the well body 100 and are connected to the well body 100. The outlet pipe 3 is connected to the well body 100. The stopcock valve 8 is used to close the overflow pipe 2. The opening degree of the stopcock valve 8 is adjusted to divert the liquid into the overflow pipe 2. In the vertical direction, the height of the inlet pipe 1 is higher than the overflow pipe 2 and the outlet pipe 3 to prevent the liquid from flowing back into the inlet pipe 1. The intercepting well body 100 can be circular or in other forms, as long as it meets the design specification requirements in the actual project. The vertical direction is as Figure 2 The up and down directions are shown in . Figure 1 In the 1-1 direction and 2-2 direction, respectively, Figure 2 and Figure 3 A cross-sectional view is shown.

[0018] The interception well of the present invention has a simple structure and is easy to construct. The intercepted water volume can be manually adjusted, which not only solves the problem of difficult to control intercepted water volume, but also reduces construction and maintenance costs, improves operational safety, and enhances sewage interception efficiency. Furthermore, the use of an inspection platform and an odor-proof structure improves the safety of personnel working underground.

[0019] In some embodiments, the angle between the axial direction of the water outlet pipe 3 and the axial direction of the water inlet pipe 1 on a horizontal plane is greater than or equal to 90°.

[0020] Specifically, when the axial direction of the outlet pipe 3 and the inlet pipe 1 on the horizontal plane is a right angle or an obtuse angle, it is conducive to water flow. It is understandable that in actual engineering, the angles of the inlet pipe 1, the outlet pipe 3 and the overflow pipe 2 can be changed and set according to the actual pipeline angle position.

[0021] In some embodiments, a mounting groove 4 is provided at the bottom of the well body 100 for fixing the stoplog valve 8 , and a hoisting hole 7 is provided at the top of the well body 100 for cooperating with the installation of the stoplog valve 8 .

[0022] Specifically, mounting groove 4, located at the bottom of wellbore 100, secures stoplog valve 8, ensuring its stability and sealing. This prevents stoplog valve 8 from being displaced by water flow, which could compromise the seal. Lifting hole 7, located at the top of wellbore 100, allows for installation of stoplog valve 8 into mounting groove 4 using lifting equipment. The design of mounting groove 4 simplifies the installation process of stoplog valve 8 and improves installation efficiency. Lifting hole 7 facilitates installation and maintenance of stoplog valve 8, reducing the complexity of manual operation.

[0023] In some embodiments, a lifting ring 9 is arranged on the top of the well body 100 , and the lifting ring 9 is used to cooperate with the movable stoplog valve 8 .

[0024] Specifically, the use of the lifting ring 9 makes it easier to adjust and replace the stoplog valve 8, reducing the labor intensity during maintenance. The lifting ring 9 can be used in conjunction with the pulley block to reduce the difficulty of underground operations.

[0025] In some embodiments, the hanging ring 9 is symmetrical with respect to the water outlet pipe 3 , and the hanging ring 9 is arranged on the inner wall of the well body 100 .

[0026] Specifically, the symmetrical arrangement of the lifting rings 9 ensures the balance of the operation and improves the safety. The two lifting rings 9 are fixedly embedded in the inner wall of the well body 100 to ensure the stability of the lifting rings 9.

[0027] In some embodiments, the intercepting well further includes a maintenance platform 5, which is located inside the well body 100 and arranged corresponding to the stoplog valve 8. A manhole 6 is provided at the top of the well body 100 for personnel to enter and exit. A plurality of steps 10 are provided on the inner wall of the well body 100, and the steps 10 are arranged equidistantly in the vertical direction.

[0028] Specifically, the maintenance platform 5 is located inside the wellbore 100, making it convenient for workers to stand and operate the stoplog valve 8. A manhole 6 is located at the top of the wellbore 100 for personnel entry and exit. Steps 10 are evenly spaced along the inner wall of the wellbore 100, facilitating safe access to the maintenance platform 5. The maintenance platform 5 improves safety and convenience for workers working downhole.

[0029] Optionally, a safety guardrail is provided outside the maintenance platform 5 to protect the safety of personnel. The safety guardrail surrounds the maintenance platform 5, protecting the safety of the staff during operation and effectively preventing the staff from falling during maintenance.

[0030] In some embodiments, the intercepting well also includes an anti-odor structure, which includes an isolation cover and a ventilation pipe. The ventilation pipe is connected to the well body 100 and is arranged obliquely relative to the well body 100. The isolation cover is used to close the manhole 6, and a rain cap is provided at one end of the ventilation pipe adjacent to the ground.

[0031] Specifically, the isolation cover seals the manhole 6, preventing odor from escaping. The ventilation pipe, connected to the well body 100, is arranged at an angle to prevent rainwater from flowing back, and the vent is protected by a rain cap. This odor-proof structure effectively isolates odors within the well and improves the surrounding environment. The design of the ventilation pipe ensures air circulation inside and outside the well while preventing rainwater from entering the well body 100.

[0032] In some embodiments, the anti-odor structure further includes an air blower, which is located in the ventilation pipe and is used to supply external air into the well body 100 .

[0033] Specifically, the blower further promotes air circulation to ensure the safety of personnel performing maintenance operations underground.

[0034] In some embodiments, flat surfaces are provided on both sides of the flow channel.

[0035] Specifically, the two sides of the flow channel are flat for ease of construction. Optionally, the height of the two inclined surfaces increases as they extend toward the inner wall of the well body 100 to reduce siltation. The inclined surface design at the bottom of the well reduces siltation at the bottom of the well, reduces the frequency of silt removal, and improves the operating efficiency of the interception well.
