The following describes a diversion well of an embodiment of the present invention with reference to fig. 1 to 3, and the diversion well comprises a diversion well chamber 1, a confluence pipe 2, a sewage pipe 3 and a rainwater pipe 4. A first chamber 11 is arranged in the diversion well chamber 1, the confluence pipe 2 and the sewage pipe 3 are respectively communicated with the diversion well chamber 1, the confluence pipe 2 and the sewage pipe 3 are respectively arranged on two sides of the diversion well chamber 1, and the axes of the confluence pipe 2 and the sewage pipe 3 are parallel. An overflow hole 14 is formed at one side of the diversion well chamber 1, the upper end of the overflow hole 14 is higher than the lower side of the sewage pipe 3, and the rainwater pipe 4 is communicated to the overflow hole 14.

In the daily operation process, after sewage enters the first chamber 11 from the confluence pipe 2, the liquid level of the sewage is lower than the lower end of the overflow hole 14, and the sewage flows out of the first chamber 11 from the sewage pipe 3; during heavy rain, the water level in the diverter well is higher than the lower end of the overflow aperture 14, and rain water can flow from the overflow aperture 14 into the rain pipe 4.

Optionally, a diversion sill 13 is disposed on a side wall of the diversion chamber 1, and an overflow hole 14 is disposed above the diversion sill 13, and when the water level is higher than the diversion sill 13, the water can flow into the rainwater pipe 4 through the overflow hole 14.

The overflow hole 14 is provided with a check valve 5 that forms a passage from the first chamber 11 to the rain pipe 4. When the water level is lower than the lower end of the overflow hole 14, the sewage does not pass through the overflow hole 14, the one-way valve 5 is in a closed state, and the one-way valve 5 can separate the rainwater pipe 4 from the first chamber 11 to play a role in isolating odor; when the water level is higher than the overflow hole 14, the check valve 5 forms a passage from the first chamber 11 to the rain pipe 4 without affecting the flow of rain water into the rain pipe 4.

In one embodiment of the present invention, a second chamber 12 is further disposed in the diversion well chamber 1, the second chamber 12 is disposed side by side with the first chamber 11, an overflow hole 14 is disposed between the first chamber 11 and the second chamber 12 and communicates the first chamber 11 and the second chamber 12, and the rain pipe 4 is communicated to the overflow hole 14 through the second chamber 12. The non-return valve 5 is able to block the passage of the second chamber 12 to the first chamber 11. By providing the second chamber 12, it is possible to provide a sufficient space for installation, operation, and maintenance of internal components such as the check valve 5.

Optionally, the non-return valve 5 comprises a valve plate 51 and an adapter, the adapter being arranged on top of the valve plate 51, the valve plate 51 being adapted by the adapter on the side of the overflow aperture 14 facing away from the first chamber 11. The check valve 5 can be automatically closed by means of the gravity of the valve plate 51, when the water level in the first chamber 11 is higher than the overflow hole 14, the passage from the first chamber 11 to the second chamber 12 can be opened in a rotating mode under the action of water pressure, and the check valve has the advantages of being simple in structure, easy to install, stable in operation, free of extra energy consumption, free of frequent maintenance and replacement and the like.

The valve plate 51 may be made of stainless steel, has good structural strength, and is not easily rusted or damaged. The adaptor can adopt a hinge 52, a rotating shaft of the hinge 52 is horizontal, the hinge 52 is fixed with a wall body through a cement nail 54, and the hinge 52 is welded and fixed with the valve plate 51.

Optionally, the number of the adapters is two or more, each adapter is arranged along the horizontal direction, and the valve plate 51 is connected with the wall body through each adapter simultaneously, so that the structural firmness and the structural stability can be improved, and the service life is prolonged.

Optionally, the lower extreme of valve plate 51 is less than the upper end of reposition of redundant personnel bank 13, and when valve plate 51 received the influence of gravity to keep vertical, the lateral wall of reposition of redundant personnel bank 13 can be laminated with valve plate 51, increases deodorant effect to reposition of redundant personnel bank 13 can also prevent that valve plate 51 from rotating to first cavity 11 one side, prevents that the rainwater from flowing backward, can also play the guard action to hinge 52.

In one embodiment of the present invention, the check valve 5 further comprises a sealing film 53, the sealing film 53 is disposed at the connecting position of the valve plate 51 and the adaptor, and the sealing film 53 is fixedly connected with the upper side wall of the overflow hole 14 and the valve plate 51 respectively. The sealing membrane 53 may be made of geomembrane and is adhesively connected to the upper wall of the overflow port 14 and the valve plate 51. The sealing film 53 can be deformed when the valve plate 51 is rotated, avoiding damage. The sealing film 53 can form a seal on the upper part of the one-way valve 5, so that the rainwater and sewage diversion well has a better deodorization effect.

Optionally, the first chamber 11 and the second chamber 12 are respectively provided with an inspection opening 15, one of the inspection openings 15 is communicated with the inner space and the outer space of the first chamber 11, the first chamber 11 can be inspected and dredged conveniently through the inspection opening 15, the other inspection opening 15 is communicated with the inner space and the outer space of the second chamber 12, the check valve 5 can be installed and maintained conveniently through the inspection opening 15, and the second chamber 12 can be inspected and dredged conveniently.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
