At mouthful the problem of water flow truncation.
2, present invention installation easy to disassemble, reusable rate are high.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is this top view.
In figure, fetch water tunnel 1, water inlet pipe 2, water inlet 3, steel cofferdam 4, fetch water active well 5, steel column I 6, steel column II 7, float
Dynamic steel column 8, support I 9, support II 10, horizontal plane 11, air sac sealing circle 12, riverbed 13, bottom plate 14, steel column leg 15.
Specific embodiment
Below in conjunction with Detailed description of the invention and specific embodiment, the present invention is described in further detail.
Referring to Fig. 1 to Fig. 2, a kind of underwater prestress steel cofferdam device of bottom sky formula for active well of fetching water, the water intaking work
Make to be connected with water intaking tunnel 1 on well 5, water inlet pipe 2 is provided on the water intaking tunnel 1, is water inlet at the top of the water inlet pipe 2
Mouth 3.Be provided with semiorbicular steel cofferdam 4 in the water intaking active well 5, semiorbicular 4 both ends of steel cofferdam respectively with water intaking
The connection of 5 inner wall of active well, 4 bottom of steel cofferdam are fixed by bottom plate 14 and water intaking 5 inner wall of active well, and water is higher than at the top of steel cofferdam 4
Plane 11.Usually when 5 depth of active well of fetching water is especially deep, use this kind of bottom sky formula structure to save material.
Referring to Fig. 1 to Fig. 2, the bottom plate 14 is fixed by steel column leg 15 and water intaking 5 bottom of active well.
Referring to Fig. 1 to Fig. 2, the 4 outer wall circumferential direction of steel cofferdam has been evenly arranged steel column I 6.
Referring to Fig. 1 to Fig. 2, I 6 outside of steel column is corresponding to be provided with steel column II 7, corresponding I 6 He of steel column
Floating steel column 8, the floating steel column 8 and steel column I 6 and steel column II 7 is provided between steel column II 7 to connect by support I 9 respectively
It connects；The support I 9 is hinged between steel column I 6, steel column II 7 and floating steel column 8 respectively, and support I 9 can turn along hinged joint
It is dynamic.First by steel column I 6 and II 7 tripping in of steel column water intaking, 5 bottom of active well when use, and it is connected and fixed with water intaking 5 bottom of active well；
Then floating steel column 8 is pressed downward again, downward pressure is reached on steel column I 6 and steel column II 7 by support I 9, so that steel column I 6
4 outer wall of steel cofferdam is held out against, achievees the purpose that steel cofferdam 4 is made to be close to water intaking active well 5 with the system for forming stable.
Referring to Fig. 1 to Fig. 2, the steel column II 7 is connect by connecting plate 10 with water intaking 5 inner wall of active well.Here by
The II 10 limitation displacements in the horizontal direction of steel column II 7 are supported, and make steel column I 6, steel column II 7, floating steel column 8 and support I 9, support
II 10 form reliable and stable linked system with water intaking active well 5.
It is close that air bag is provided with referring to Fig. 1 to Fig. 2, between semiorbicular 4 both ends of steel cofferdam and water intaking 5 inner wall of active well
Seal 12.After steel cofferdam 4 is close to water intaking active well 5 and starts to take out the water in steel cofferdam 4, by different inside and outside steel cofferdam 4
Pressure make air sac sealing circle 12 expand, reach hermetic seal effect.
Referring to Fig. 1 to Fig. 2, first by the 4 tripping in water of semi-circular steel cofferdam with steel column leg 15 when use, 15 bottom of steel column leg
It is connected and fixed with water intaking 5 bottom of active well；Steel column I 6 and steel column II 7 are set again, are each attached to steel column I 6 and II 7 bottom of steel column
Water intaking 5 bottom of active well, is then pressed downward floating steel column 8, and downward pressure reaches steel column I 6 and steel column II 7 by support I 9
On, so that steel column I 6 holds out against 4 outer wall of steel cofferdam, the mesh for making steel cofferdam 4 be close to water intaking active well 5 is reached with the system for forming stable
's.Finally the water inside steel cofferdam 4 is drained, makes the expansion of air sac sealing circle 12 to reach by pressure different inside and outside steel cofferdam 4
To the effect of the complete sealing in all junctions.Therefore the present invention ensure that water intaking tunnel by increasing the measure of steel column support system
1 detection with reinforcement operation during at water inlet 3 will not leak influence the safety of construction personnel, for tunnel 1 of fetching water detection with plus
Admittedly providing operating condition, solves the problems, such as the truncation of 3 water flow of water inlet.
