Preferably, the intercepting part 3 in this embodiment may be a device such as a gate, a weir gate, or a flexible intercepting device installed in a well body structure such as an installation well, or may be a flexible intercepting device directly plugged into a pipeline, and it is within the scope of the present invention for those skilled in the art to realize that the device capable of conducting or stopping the water flow at the position where the intercepting part 3 is located.
Example III
Referring to fig. 5, a third embodiment provides a drainage system based on modification of an existing septic tank, which comprises the buffer tank 4, the unit area 1 and the municipal merging pipe 2 in the second embodiment, wherein the unit area 1 comprises at least one sewage branch pipe 10, at least one rain water inlet 11 and a merging branch pipe 12, the sewage branch pipe 10 is communicated with the buffer tank 4 and the merging branch pipe 12, the rain water inlet 11 is communicated with the merging branch pipe 12, the tail end of the merging branch pipe 12 is connected with the municipal merging pipe 2, and the sewage branch pipe 10 and the rain water inlet 11 are connected with the merging branch pipe 12, but no direct communication relationship exists between the sewage branch pipe 10 and the rain water inlet 11.
In this embodiment, the specific structure of the buffer pool 4 is referred to in the second embodiment, and will not be described again. This drainage system is on the sunny day, opens the shutoff portion 3, and the domestic sewage that unit region 1 flows out to municipal administration and closes the flow tube 2 from sewage branch pipe 10 after the fender sediment is blocked to buffer pool 4, and in the rainy day, closes the shutoff portion 3, and the domestic sewage that flows out in the unit region 1 is in buffering pool 4 temporary storage, and rainwater that the inlet for stom water 11 assembled at this moment is carried to municipal administration and is closed the flow tube 2, after the sunny day, opens the shutoff portion 3 again, carries temporary stored domestic sewage to municipal administration and closes in the flow tube 2. All be domestic sewage in the municipal administration confluence pipe 2 that carries when sunny day, all be the rainwater in the municipal administration confluence pipe 2 that carries during rainy day, need not to reform transform municipal administration confluence pipe 2, only utilize the function that fills pond 4 in unit area 1 can satisfy sewage transportation and temporary storage, realize the storage transportation to sewage under the condition of less land area, avoided rainwater and domestic sewage to mix from the source, solve the problem that confluence tubulation net exists from the source.
Finally it should be noted that while the preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments will occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the invention. It will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments of the present invention without departing from the spirit or scope of the embodiments of the invention. Thus, if such modifications and variations of the embodiments of the present invention fall within the scope of the claims and the equivalents thereof, the present invention is also intended to include such modifications and variations.
