Description
Technical field
The utility model be related to a kind of subway cross dewatering type tunnel between sea area auxiliary it is simultaneous transfer drainage pumping plant, particularly exist
Do not increase under the premise of civil engineering water collecting pool volume, realize that mode of operation switches by automatically controlling, can termination of pumping maintenance.Suitable for subway
The displacement for crossing dewatering type tunnel between sea area is big, the features such as interval length, buried depth are deep, improves the economy of operation draining and reliable
Property.
Background technology
With Qingdao, Xiamen etc. border on the sea archipelago city track traffic it is fast-developing, increasing rail line
Bay is passed through by city island economy regional connection, this is accomplished by building numerous seabed tunnels.The water of seabed tunnel
Position is general higher, and tunnel is larger by water pressure.Therefore half bag waterproof is used the waterproof of seabed tunnel more, reduce water pressure, structure
Stress reduces, but causes tunnel drainage amount big and continue.By taking certain the highway seabed tunnel put into effect at present as an example, structure is adopted
With half bag water-proof drainage type tunnel, daily operation displacement is of about 4000m3/d.Certain is in design phase subway seabed tunnel structure
Specialty provides displacement data, structure drainage amount about 3600m3/d.Meanwhile, subway seabed tunnel length is long, and buried depth is deep, tunnel
Total length is in 8 kms, and seabed bosom, up to 80m or so, such as sets pumping plant by seabed and disposably lift discharge away from ground height
Outdoor, pump head is up to more than 120 meters, and water pump is difficult to realize, and the too high lifting pipe pressure-bearing of lift is excessive easily occurs water hammer
Accident.Therefore other feasible, reliable and more economic pumping station layout schemes need to be explored.
To reduce pump head, the Jiaozhou Bay tunnel over strait put into operation at present is lifted using secondary pumping station.In seabed tunnel
Road minimum point sets main pumping station, is set in main pumping station both sides and transfers pumping plant.But the upstream tunnels water that pumping plant is transferred in both sides is complete
Retain to this and transfer in pumping plant, it is impossible to realize that the termination of pumping for transferring pumping plant is safeguarded, broken down when transferring pumping plant, upstream structure draining
It can not exclude in time.In other designs, to meet the termination of pumping maintenance for transferring pumping plant, it need to increase and transfer pumping plant collecting-tank appearance
Product, will be divided into two parts standby each other, program increase construction investment expense and difficulty of construction, and separate in collecting-tank
The unnecessary volume that goes out is daily effectively to be utilized, and cause the wasting of resources.At present, dewatering type tunnel between sea area is crossed specifically designed for subway
Road aids in the simultaneous optimization design for transferring drainage pumping plant still to belong to blank beyond example.It would therefore be highly desirable to research and develop a kind of feasible, reliable, warp
The auxiliary of Ji is simultaneous to transfer drainage pumping plant, and the construction and operation crossing sea area to subway underground have important value and significance.
The content of the invention
For prior art blank, the purpose of this utility model is to provide a kind of subway and crosses the auxiliary of dewatering type tunnel between sea area
Help it is simultaneous transfer drainage pumping plant, the pumping plant can both receive upstream tunnels structure gravity drainage, while transferring downstream pump station water
Lifting, can not receive upstream tunnels structure gravity drainage, upstream drainage is surmounted the pumping plant and be immediately discharged to downstream, meet the pump again
The termination of pumping maintenance stood is with safeguarding.
