A maintenance manhole, a maintenance steel ladder, a submersible sewage pump, a steel casing, and an emptying pressure rainwater pipe are installed in the initial abandonment well. , the steel casing is set in the side wall of the conversion well and set outside the drain pressure rainwater pipe.

A movable cover plate is arranged on the upper part of the rainwater conversion well.

The beneficial effects of the utility model are:

1. Since the utility model integrates rainwater storage and collection and reuse, the land area is saved;

2. The utility model controls the flow direction of the rainwater by the height of the overflow weir, and the rainfall does not enter the storage tank when the rainfall is small, which saves the cost of emptying, low operating cost, simple management, and is suitable for popularization and use.

detailed description

The technical solution of the utility model will be described clearly and completely through the examples below, obviously, the described embodiments are only a part of the examples of the utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

A multi-functional rainwater conversion well as shown in Figures 1 to 3, including a conversion well side wall 14, an initial abandonment well 7, a first overflow weir 121, a second overflow weir 122, and a third overflow weir 123 , the side wall 14 of the conversion well is respectively provided with a multi-functional rainwater well inlet pipe 1, a water reservoir inlet pipe 8, a small flow direct discharge municipal rainwater pipe 9, a straight discharge municipal rainwater pipe 11, and a raw water pool inlet pipe 10. The first overflow The heights of the flow weir 121, the second overflow weir 122, and the third overflow weir 123 are successively increased to control the flow direction of rainwater. The initial abandonment well 7 is connected to the multifunctional rainwater well inlet pipe 1, and the second overflow well The pool formed by the flow weir 122 and the side wall 14 of the rainwater conversion well It is connected with the water storage tank inlet pipe 8 and the small flow direct discharge municipal rainwater pipe 9, and the pool formed by the third overflow weir 123 and the side wall 14 of the rainwater conversion well Connected with the straight-line municipal rainwater pipe 11, the pool formed between the first overflow weir 121, the second overflow weir 122, the third overflow weir 123, and the side wall 14 of the conversion well It is communicated with the water inlet pipe 10 of the raw water pool.

Further, an inspection manhole 2, an inspection steel ladder 3, a submersible sewage pump 4, a steel casing 5, and an emptying pressure rainwater pipe 6 are set in the initial abandonment well 7, and a submersible sewage pump is arranged at the bottom of the initial abandonment well 7. 4. The submersible sewage pump 4 is connected to the emptying pressure rainwater pipe 6, the steel casing 2 is set in the side wall 14 of the conversion well and is sleeved outside the emptying pressure rainwater pipe 6, and the maintenance manhole 2 is located on the upper part of the initial abandonment well 7 .

Further, a movable cover plate 13 is arranged on the upper part of the rainwater conversion well.

In the utility model, after the rainwater enters the initial runoff well 7, the initial runoff well 7 can store the rainwater of the initial runoff, and the suspended matter and magazines in the rainwater are deposited at the bottom of the pool. Reservoir inlet pipe 8 is the same elevation as raw water inlet pipe 10 (pipe bottom elevation), which is lower than multifunctional rainwater well inlet pipe 1. The water inlet pipe 8 of the reservoir and the water inlet pipe 10 of the original water pool are separated by a second overflow weir, and the rainwater first enters the pool after passing through the initial abandonment well (Rainwater Raw Pool), Guaranteed Pool source of water. The elevation of the small-flow municipal rainwater pipe 9 is lower than that of the reservoir inlet pipe 8. When the rainfall is small, the rainwater can be discharged into the municipal rainwater pipe 9 through the small-flow municipal rainwater pipe 9, so as to avoid frequent start-up of the submersible sewage pump and save operating costs. When storing full rainwater, the collected rainwater is discharged into the municipal rainwater pipe 11 by the straight row municipal rainwater pipe. When the rainstorm is over, drain the rainwater within 12 hours.

When the rainfall is relatively small, the rainwater does not enter the pool , when the rainfall ends, the rainwater in the initial abandonment well 7 is emptied by artificial control, and the rainwater is discharged into the municipal rainwater pipe through the pipeline. During heavy rainfall, rainwater enters the pool , play a role in reducing the flood peak. After the end of the rain, the pool should be removed within 12 hours emptying of rainwater. Rainwater is piped into municipal storm sewers.

The above-mentioned embodiments only represent the implementation of the present utility model, and the description thereof is relatively specific and detailed, but should not be construed as limiting the scope of the present utility model. It should be pointed out that those skilled in the art can make some modifications and improvements without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
