[0002] Sewage interception wells can intercept sewage mixed in the rainwater pipe network and use submersible pumps to force the sewage to be discharged into a special sewage pipe network. Traditional sewage interception wells have a simple structure and a single function. While intercepting sewage, they are prone to cause sewage to flow back into the river directly, or cause waterlogging in rainy weather due to the overflow weir raising the water level of the pipe network. The existing intelligent integrated sewage interception wells can solve the above problems, but the structure is complex and the cost is relatively high, so they cannot be widely promoted and applied. At the same time, most traditional sewage interception wells are made of reinforced concrete cast-in-place technology, which has a long construction period and high construction cost, affecting the progress control of the renovation project. Therefore, it is necessary to optimize and improve the existing sewage interception well structure. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0017] like Figure 1-2 As shown, a new type of finished sewage interception well comprises a well seat 1, a well chamber is arranged inside the well seat 1, a water inlet pipe 2 is connected to one side of the base, and a water outlet pipe 3 is connected to the other side, the water inlet pipe 2 and the water outlet pipe 3 are connected to the well chamber respectively, a partition plate 4 is arranged in the well chamber, the partition plate 4 divides the well chamber into a front well chamber 5 and a rear well chamber 6, a front well shaft 7 and a rear well shaft 8 are fixedly connected to the well seat 1, the lower end of the front well shaft 7 is connected to the front well chamber 5, the upper end of the front well shaft 7 is provided with a front wellhead 9, the lower end of the rear well shaft 8 is connected to the rear well chamber 6, and the rear well shaft The upper end of the well 8 is provided with a rear well mouth 10, and the rear well mouth 10 and the front well mouth 9 are respectively covered with a well cover 11, and the partition 4 is provided with a water hole 12, and the front well chamber 5 and the rear well chamber 6 are connected through the water hole 12, and an air bag 13 is installed in the water hole 12, and the air bag 13 is connected to the inflation tube 14, and an overflow pipe 15 is connected between the front well shaft 7 and the rear well shaft 8, and a plurality of sewage pumps 16 are installed in the front well chamber 5, and the sewage pumps 16 are respectively connected to sewage pipes 17, and the well seat 1 is provided with an extension port 18 for the sewage pipe 17 to extend. The height of the overflow pipe 15 is higher than the normal water level of the river connected to the outlet pipe 3. Under normal use on sunny days or in the early stage of rainfall, the air bag 13 is filled with gas, and the air bag 13 blocks the water hole 12. Sewage or initial rainwater enters the front well chamber 5 from the water inlet pipe 2. When the sewage in the front well chamber 5 reaches a certain height, the sewage pump 16 is started to pump the sewage at the bottom to a special sewage well for sewage treatment. When the water flow rate of the water inlet pipe is greater than the rated flow rate of the sewage pump, the water level in the front well chamber 5 rises, flows into the rear well chamber 6 from the overflow pipe 15, and is discharged into the river through the outlet pipe 3. When heavy rain occurs, the gas in the airbag 13 is discharged by opening the valve on the inflation pipe 14, so that the front well chamber 5 and the rear well chamber 6 are connected through the water hole 12, and the water flow flattens the airbag 13 so that it is completely deflated and sinks to the bottom of the water hole. The rainwater directly enters the rear well chamber 6 from the front well chamber 5 and is then discharged. After the rain, when the rainwater in the rainwater pipe network is basically emptied, the airbag 13 can be re-inflated to block the water hole 12, and the sewage interception well can resume working under sunny conditions.
[0018] Further, an anti-falling net 19 is provided in the rear wellhead 10 and the front wellhead 9, and the four sides of the anti-falling net 19 are connected to the front wellbore 7 or the rear wellbore 8 by hooks. The anti-falling net 19 prevents people or animals from falling into the sewage interception well when the well cover 11 is removed.
[0019] Furthermore, the sewage pump 16 is connected to the sewage pipe 17 through a flange, and a hanging chain 20 is connected to the sewage pump 16. The lower end of the hanging chain 20 is connected to the sewage pump 16, and the upper end of the hanging chain 20 is hung on the front wellhead 9 through a hook. When the sewage pump 16 needs to be maintained, the flange is disconnected, and the sewage pump 16 is moved to the front wellhead 9 by using the hanging chain 20, so that the maintenance personnel can inspect the sewage pump 16 on the ground. After the inspection is completed, the sewage pump 16 is put down and automatically coupled. The maintenance personnel do not need to inspect the sewage pump 16 inside the wellbore for a long time, which improves the safety of the operation.
[0020] Furthermore, a plurality of slide rails 21 are provided in the front shaft 7 , and sliders are provided on the slide rails 21 , respectively. The sliders are connected to coupling bases 22 , and the sewage pumps 16 are respectively installed on the coupling bases 22 .
[0021] Furthermore, a mesh cover 23 is fixedly installed around the sewage pump 16. The mesh cover 23 prevents debris from being sucked into the sewage pump 16 and affecting the operation of the sewage pump 16. The mesh cover 23 and the sewage pump 16 can be lifted out of the wellbore for cleaning and maintenance through the lifting chain 20.
[0022] Furthermore, the four sides of the airbag 13 are connected to the well seat 1 by fixed chains 30. The airbag 13 is fixed in the well chamber by the fixed chains 30. When the airbag is completely deflated and sinks to the bottom of the water hole, it can only move within a small range due to the action of the fixed chains 30, and can be reset when inflated again.
[0023] Furthermore, a float type liquid level switch 24 is provided in the front shaft 7, and the float type liquid level switch 24 controls the start and stop of the sewage pump 16. The float type liquid level switch 24 starts or stops the sewage pump 16 according to the liquid level of the sewage in the sewage interception well, eliminating manual control and realizing automatic discharge of sewage.
[0024] Furthermore, the manhole cover 11 is a ductile iron manhole cover 11.
[0025] Furthermore, the well base 1, FRP partition 4, airbag 13, fixed chain 30, sewage pump 16, etc. are all prefabricated and assembled in a workshop, and can be transferred to the construction site for assembly with other components during construction, thereby shortening the construction period.
[0026] It is worth mentioning that the technical features such as the float liquid level switch 24 and the sewage pump 16 involved in the utility model patent application should be regarded as the prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the invention point of the utility model patent. The utility model patent will not be further elaborated.
[0027] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the utility model on the basis of the existing technology should be within the scope of protection determined by the claims.
