Description
Technical field
The present invention relates to a kind of underwater ground anchor structures, belong to water conservancy and hydropower technical field.The present invention relates to one kind being used for water
The anchoring underwater structure of hydropower reservoir station water proof, water blocking curtain wall construction.
Background technology
High dam big library in power station will generate important shadow after building up to the water temperature spatial and temporal distributions in reservoir area waters and dam lower reache
It rings.Especially at the end of spring and the beginning of summer cause reservoir to go out flowing water temperature and be less than natural river course, low-temperature discharge is to downstream fish and other are aquatic
Biological self reproducing etc. adversely affects.To improve the temperature that sluices under Built hydropower station reservoir, under certain engineering measure need to be taken to ensure
Swim the normal existence environment of aquatile.In recent years, the flexible water blocking curtain wall knot that a kind of structural shape is simple, investment is relatively low
Structure is being proposed for administering the big library low-temperature discharge problem of high dam.Low temperature water harnessing water partition curtain wall is in the previous positioning of dam
Yokogawa is set to the impermeable water curtain wall of flexibility for arranging suitable water retaining height, underlying low temperature water, overcurrent surface layer high temperature are stopped by curtain wall
Water achievees the purpose that improve the lower warm curtain formula layered water drawing structure that sluices.
Water proof curtain wall bears hydrostatic pressure caused by water pressure load, including flowing pressure and temperature, mainly by water pressure
Load passes to longitudinal drag-line by flexible curtain wall, and load is transferred to top Sarasota structure and bottom storehouse earth anchor knot by longitudinal drag-line again
Structure.Wherein the pulling force of curtain wall longitudinal direction drag-line, stress are born in bottom storehouse ground anchor structure upper end for hanging water proof curtain wall longitudinal direction drag-line
And design feature has：
1）Curtain wall longitudinal direction drag-line is oblique pulling to the pulling force of ground anchor structure.Water proof curtain wall construction is during running use, curtain wall
With vertical direction there are certain angle, curtain wall longitudinal direction drag-line is obliquely to underwater ground anchor structure direction of pull for longitudinal drag-line lower end
Side.
2）Curtain wall longitudinal direction drag-line is directed varying forces to the pulling force of ground anchor structure.Water proof curtain wall is with reservoir level in normal pool level
Change and automatic lifting between level of dead water, curtain wall and longitudinal adaptive SEA LEVEL VARIATION of drag-line adjust its form.Difference operation water
The position cross-section of river, water velocity, pressure distribution are all different, thus curtain wall and longitudinal drag-line build form are also different, pass
The pulling force size and Orientation for being handed to underwater ground anchor structure is also all different.
3）Curtain wall longitudinal direction drag-line is larger to the pulling force magnitude of ground anchor structure.It is estimated that water proof curtain wall water retaining height 140m is left
When right, longitudinal drag-line is arranged to spacing for 10m by Yokogawa, water proof curtain wall longitudinal direction drag-line is transferred to the maximum value of ground anchor structure resultant force
About 800kN or so, after being decomposed into vertical force and horizontal force, vertical force and horizontal force maximum value are much larger than up to 500-600kN
The pulling force magnitude that general ground anchor structure is born, especially horizontal pull.
4）Ground anchor structure upper end need to be useful for hanging the connecting elements of water proof curtain wall longitudinal direction drag-line.
Existing earth anchor（Anchoring）Structure cannot meet the underwater ground anchor structure requirement of water proof curtain wall：
1）Rock anchor assembly is a kind of common ground anchor structure, is to pour into dowel and mortar (or concrete) in rock-boring, with
Rock bonding is integral, bears the ground anchor structure pattern of certain pulling force to the wedge action of pile body by Rock And Soil.By deep water
Underwater construction condition limits, and water partition curtain wall rock anchor assembly bore diameter is generally less than 150mm（When bore diameter is more than 150mm, apply
Work steel pile casting size, dead weight etc. will increase, and underwater construction, operation difficulty is significantly greatly increased）, the rock under the bore diameter restrictive condition
The horizontal pull that killagh stake provides is limited, particularly when anchoring pile passes through weak, loose rock-soil layer because of Rock And Soil lateral spacing drag not
Foot, rock anchor assembly easily fracture destruction, failure, can not adapt to curtain wall longitudinal direction drag-line to the pulling force of ground anchor structure be size with
The complicated operating condition that direction changes.
2）Traditional prestressed anchor Cable Structure can bear larger axial tension, but cannot bear greater level power, can not
Adapt to the complex working condition of curtain wall operation, and anchor cable anchor pier pours deep water underwater construction there are larger difficulty, the upper end arrangement and curtain
There is also difficulties for the connecting elements of wall longitudinal direction drag-line.
