Description
Technical field
This utility model relates to Hydraulic and Hydro-Power Engineering technical field, especially a kind of hydroenergy storage station Inlet and outlet water saliva bank
Safeguard structure.
Background technology
Side slope near the hydroenergy storage station intake-outlet of the northern area of China, throughout the year by wave impact scour, daily take out
Sudden drawdown that water generating produces and the multiple-disruption such as frost heave of winter severe cold, easily cause bank protection near intake-outlet and cave in peeling
Destroy.
Traditional intake-outlet side slope, for new construction, if within the protection domain of cofferdam, because there being dry work bar
Part, constructs more convenient；If beyond scope is blocked in cofferdam, or the reparation of built engineering breakage side slope, nothing will be there is
The problem of dry work condition.To this, the method generally used is underwater dumped rockfill, waterborne build stone masonry, loose stone by laying bricks or stones or pours
Concrete is as the support form of side slope.Such side slope type is frequently by wave stroke scour, sudden drawdown and frost heave in winter
Effect, often due to anti-filter mass defect or without filtration material, causes anti-filter to lose efficacy, so that being positioned at the soil body of bottom by scour,
Cause and come to nothing, make slop protection material lose supporter and cause domatic caving in, make shore protection overall or local is damaged；Or due to rigidity
Bank protection and bed course (or anti-filter) thickness, less than local maximum depth of frozen ground, cause to be kept off and protect soil body generation frost heave, make bank protection body quilt
Spalling destroys, then by wave scour, causes bank protection to cave in pull out type fracture.These destructions will often carry out repair, due to
Built engineering is by day-to-day operation condition and does not has the conditions such as construction road to be restricted, and repair is relatively difficult, and expends a large amount of
Manpower and materials.
It addition, hydroenergy storage station is many in scenic spot, the slope protection form such as concrete or stone masonry, not only easily occur with
Upper problem, meanwhile, is also easy to be formed artificial trace and the negative view of Lycoperdon polymorphum Vitt of stiff " armored concrete forest " formula, easily with
Surrounding and view are inharmonious.
Therefore, design a kind of safe and feasible, adapt to surrounding, economical rationality, the slope protection structure of easy construction, come
The combined influences such as reply hydroenergy storage station intake-outlet wave, sudden drawdown and frost heave, become a kind of requirement of engineering.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of hydroenergy storage station Inlet and outlet water saliva bank protection knot
Structure, on the basis of hydroenergy storage station intake-outlet side slope is effectively protected, solve frequently wave stroke scour, daily take out
Bank protection is caved in pull out type fracture problem by sudden drawdown that water generating produces and the frost heave of winter severe cold, and adapt to surrounding,
Economical rationality, easy construction.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of hydroenergy storage station turnover
Mouth of a river water bank safeguard structure, including be positioned under water with the rock revetment in fluctuation of water table district, be positioned at bank protection waterborne waterborne and be positioned at
The packway at bank protection top waterborne, described protective slope structure waterborne by inner and table be followed successively by anti-filter geotextiles, sand gravel or blotter,
Gabion bank protection.
Described anti-filter geotextiles arranges hairiness sand bedding course further below.
Described rock revetment, its Slope is than for 1:1.2-1:1.5, and end face exceeds power station day-to-day operation high-water line 0.2-
0.5m, bottom is less than lowest water level line 1.5-2.5m.
Described gabion bank protection thickness is 0.4-1m.
Described gabion bank protection is in galvanized wire gabion, reinforced gabion, geogrid gabion, lattice guest's gabion and ZHUSHI cage
Kind.
Described sand gravel or blotter thickness 0.15-0.6m, and described sand gravel or blotter protect with described gabion
The thickness sum on slope is more than engineering location maximum depth of frozen ground.
The specification of described anti-filter geotextiles is more than or equal to 300g/.
Described hair sand bedding course thickness is 2-10cm.
Packway more than described bank protection waterborne is that loose stone, gabion, sand gravel, graded broken stone, mud calculus are built by laying bricks or stones or filled
Flexible structure, it sets the 1%-3% gradient to gabion bank protection direction.
The construction method of a kind of hydroenergy storage station Inlet and outlet water saliva bank safeguard structure, comprises the following steps:
A, to below day-to-day operation high-water line side slope use jackstone reinforce, jackstone grade of side slope controls at 1:1.2-1:
1.5, jackstone side slope end face exceeds day-to-day operation high-water line 0.2-0.5m；
B, to bank protection waterborne, by artificial or hand fit is mechanical, excavation slope is to designing build, if excavation face manually flattens
After, when surface does not exist the stone foreign body that can puncture geotextiles, directly anti-filter geotextiles is layered in the excavation face after leveling；If
After excavation face manually flattens, when surface existence can puncture the stone foreign body of geotextiles, at the hair sand pad that excavation face paving 2-10cm is thick
Laying anti-filter geotextiles after Ceng on hair sand bedding course, anti-filter geotextiles lower edges affluence to be reserved, with wrapping portion sand gravel
Or blotter, upper anchorage and bottom pressure pillow as anti-filter geotextiles are used；
C, in anti-filter geotextiles, lay sand gravel or blotter, after using vibro-rammer compacting, by anti-filter geotextiles
Under the affluence that reserves partially folded, parcel sand gravel or blotter upper-lower position, carry out the anchoring of sand gravel or blotter
And pressure pillow；
D, on sand gravel or blotter lay gabion complete protective slope structure waterborne；
E, on the water protective slope structure top making packway, during laying, end face reserves the slope to gabion bank protection direction 1%-3%
Degree, in order to draining.
The beneficial effects of the utility model are: on the basis of effectively protecting hydroenergy storage station intake-outlet side slope,
Efficiently solve sea slap frequently washes away, daily generating of drawing water produces sudden drawdown and the freeze thawing of winter severe cold to bank protection
Pull out type fracture problem of caving in, adapt to surrounding, economical rationality, easy construction.The most domatic use from bottom to top jackstone,
Gabion protects, and carries out bed course and anti-filter bottom gabion, more than bank protection uses the flexible material revetment packway tops such as loose stone, overall
Slope protection structure, while the wave gear that disappears protects, greatly strengthen its adaptability to deformation.Meanwhile, with natural environment phase around
Coordinate, without structures such as concrete, armored concrete, stone masonries, it is to avoid the building of stiff " armored concrete forest " formula
And protection form, top is conducive to the covering of green plants, had both met requirement of engineering, again natural harmony.
