Outlet pipe, the water inlet pipe that shuts off sequentially passes through shaft bottom buried depth layer and enclosure wall is connected with the cavity of the enclosure wall other side, and described section
Outflow water pipe passes through the well body other end and is connected with cavity.
In the above-mentioned technical solutions, a kind of river bank reverse-filling type Vatch basin, it is characterised in that：The well body borehole wall
The spheroidal graphite cast-iron positioned at well lid bottom is equipped with to mark time.
In the above-mentioned technical solutions, a kind of river bank reverse-filling type Vatch basin, it is characterised in that：It is set in described hole
There is grid.
In the above-mentioned technical solutions, a kind of river bank reverse-filling type Vatch basin, it is characterised in that：The shaft bottom buried depth
Layer top is equipped with catch pit.
In the above-mentioned technical solutions, a kind of river bank reverse-filling type Vatch basin, it is characterised in that：On the duckbill valve
Equipped with water string.
In the above-mentioned technical solutions, a kind of river bank reverse-filling type Vatch basin, it is characterised in that：The well lid is close
Envelope type well lid.
In the above-mentioned technical solutions, a kind of river bank reverse-filling type Vatch basin, it is characterised in that：The duckbill valve valve
Bottom absolute altitude is higher than the outlet pipe tube top absolute altitude that shuts off.
The utility model has the beneficial effects that：One, when ensuring that flood level is higher than manhole cover, will not flow backward；Two, have
Effect solves in status sewage draining exit that a large amount of suspended matters and floating material enter Vatch basin, can substantially reduce the frequency that Vatch basin is blocked
Rate reduces the sludge accumulation in downstream line, it is ensured that effective operation of sewage plant；Three, operating cost is low, cheap, more
It is reliable and practical；Four, duckbill valve is increased, when flood level can be effectively prevent to be higher than duckbill valve, is flowed backward from overflow pipe.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
A kind of river bank reverse-filling type Vatch basin as shown in Figs. 1-5, including well body 1 are equipped with enclosure wall in the middle part of the well body 1
1.1, hole 1.2 is opened up on the enclosure wall 1.1, is equipped with grid 1.3 in described hole 1.2.Difference is equipped at the top of the well body 1
Well lid 2 positioned at 1.1 two sides of enclosure wall, the well lid 2 are steel, and are sealed manhole cover.Every well lid 2 is mating equipped with one
Rubber washer and 6 stainless steel bolts, matching washer and nut below each stainless steel bolt add up to 6 sets.
The spheroidal graphite cast-iron that 1 borehole wall of well body is equipped with positioned at 2 bottom of well lid marks time 2.1.It is passed through on the side wall of the well body 1
It wears and is equipped with status sewage draining exit 3, run through on 1 side wall of well body of 3 opposite side of status sewage draining exit and be equipped with duckbill valve 6, it is described
Duckbill valve 6 is equipped with water string 6.1, and model and the duckbill valve 6 of the water string 6.1 match.
1 bottom of well body is equipped with the shaft bottom buried depth layer 1.4 between 1 one end of well body and enclosure wall 1.1, and the shaft bottom is buried
Catch pit 1.5 is equipped at the top of deep layer 1.4.
1 both ends of well body are respectively equipped with the water inlet pipe 4 that shuts off with the outlet pipe 5 that shuts off, and the water inlet pipe 4 that shuts off sequentially passes through
Shaft bottom buried depth layer 1.4 and enclosure wall 1.1 are connected with the cavity 1.6 of 1.1 other side of enclosure wall, and the outlet pipe 5 that shuts off is across well body 1
The other end is connected with cavity 1.6.The 6 valve bottom absolute altitude of duckbill valve is higher than the 5 tube top absolute altitude of outlet pipe that shuts off.
When fine day, the water of status sewage draining exit 3 is equipped with steel grating 1.3 by hole 1.2 and flow in the outlet pipe 5 that shuts off, in turn
Into downstream wastewater, treatment plant is handled.When the rainy day, with the increase of amount of rainfall, downstream shut off outlet pipe 5 with flowing full will cut
The combined sewage for flowing into water pipe 4 and status sewage draining exit 3 is sent to sewage plant processing.It is mixed when status sewage draining exit 3 and the water inlet pipe 4 that shuts off
Close sewage quantity be more than downstream shut off outlet pipe 5 design conveyance power of water when, Vatch basin starts overflow, and the combined sewage of overflow passes through
Duckbill valve 6 drains into river.When rain time continues to extend, due to the decrease of rainfall intensity, the flow at Vatch basin is reduced,
Spillway discharge reduces.Finally, combined sewage amount is equal to or less than the design conveyance power of water for the outlet pipe 5 that shuts off again, overflow stops.
In the whole process, if flood level is higher than well lid 2, river water reverse irrigation and river water will not occurs from well lid 2 and flow into Vatch basin
Problem.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
