First discharge port 5 is arranged on pit shaft 1, and one-way cock 6 is arranged on the outside of first discharge port 5.One-way cock 6 can be duckbill valve
Or flap valve.The position that the top of first discharge port 5 is located below the flood season level line S at the position that Vatch basin is installed,
The position that the bottom of downflow weir 4 is located is higher than flood season level line S.
The occurrence of flood season level line is different according to different cities or area.Specifically, for realizing water conservancy
For the city of big encirclement or the control of city's freshwater line, flood season level line is the controlled water level in flood season for the river course, exceedes and is subject to
During control water level, the water of interior korneforos is pumped to periphery by water conservancy drainage pumping stations.For being not carried out, water conservancy is big to surround or city river
For the uncontrolled city in position, flood season level line takes 1 year 1 chance (standard can be different with various places situation) flood level highest
Value.Usually, with the height at flood season level line S place as basis reference, it is set to 0m, then height that above-ground route E is located is 2.3m, fine
Its normal water line L is then in the lower section of flood season level line S.Different cities or area, both differences are different, need basis to dam
The particular location that well is installed determines.For example, fine day normal water line L is probably differed with flood season level line S taking Changzhou as a example
0.3m.Additionally, flood season level line " controlled waterline when really rainy day river water level is controlled.Some cities are in water conservancy management
Aspect not using strict control flood season level line by the way of, but typically also have flood level duration curve, then this specific embodiment
Flood season level line is also covered by the flood level duration curve in corresponding some cities or area.

In addition, the manhole 10 shown in figure is opened in the top of pit shaft 1, enters in pit shaft in order to staff and tieed up
Repair or emergency processing.
Sewage or rainwater enter Vatch basin by water inlet pipe 100.During Vatch basin work, in fine day, only sewage enters,
By entering sewage lifting pump station after the mouth 3 that dams, reach sewage treatment plant afterwards.During the rainy day, when Rainwater Initial or rapid and short
Temporary rain during, enter rainwater less when, the mouth 3 that dams also by pit shaft 1 bottom enters sewage lifting pump station, and obstructed
Cross first discharge port and enter river course, in order to avoid polluted river channel.When rainwater mid-term, the rainwater of entrance is more, then pumping plant side stops
Work, in order to avoid a large amount of rainwater enters sewage treatment plant.Now, the rainwater of sludgd deposition accumulation in wellbore bottom, pit shaft reaches
During the height that first discharge port 5 is located, enter in river course R by after one-way cock 6, thus realizing effective during rainwater middle and late stage
Rain is dirty to be separated.When rainwater middle and late stage or heavy rain, in pit shaft, the rainwater of accumulation is more, after reaching the height that downflow weir 4 is located,
Cover downflow weir 4 and flow into river course R, then can achieve quick flood discharge, thus that reduces upstream coverage floods flooded risk.
Preferably, Vatch basin also includes the second floss hole 7, gate 8, liquidometer and control system.Second floss hole 7 is arranged

Meter (in figure does not illustrate), outfan connects gate 8, the keying of the water level signal regulating gate for transmitting according to liquidometer.
During work, when persistent heavy rainfall, the accumulation of rainwater in pit shaft 1 persistently increases, when being also not enough to quick flood discharge by downflow weir 4
When, upstream coverage is flooded flooded risk and is increased.When the liquid level in pit shaft 1 reaches certain altitude, for example nearer apart from above-ground route E
When, control system controls opens gate 8, thus passing through this direct flood discharge of gate 8, to reach the quick flood discharge under the state of emergency,
That reduces upstream coverage further floods flooded risk.
Preferably, the fine day ordinary water level at position that the position that the top of the second floss hole 7 is located is installed with Vatch basin
Line L is in sustained height.During the rainy day, when opening the second floss hole 7, if floss hole position is relatively low, flow velocity is larger, easily will manage
In road, the pollutant of deposition wash away out, polluted river channel.If floss hole position higher it is impossible to play dump flood discharge work
With.The top of the second floss hole 7 is maintained an equal level with fine day normal water line L, thus dropping as far as possible on the premise of playing flood discharge effect
Flow velocity when low second floss hole 7 is opened, reduces and pipeline is washed away, thus reducing the pollution to river course.
The Vatch basin of this specific embodiment, the mouth that dams, first discharge port (one-way cock) and downflow weir are arranged on difference
Height at, the mouth that dams is located at bottom, and first discharge port is placed in the middle, and the position highest of downflow weir so, gradually can increase in rainwater
