Description
Technical field
Wall, which is led, with spillway with the rock of water guide wall function the utility model relates to taking into account a kind of toe board connect knot
Structure, the connection of face dam and discharge structure spillway suitable for hydraulic and hydroelectric engineering.
Background technique
Face dam and spillway joint area structure are more complicated in hydraulic and hydroelectric engineering, and the more difficult arrangement of toe board connects simultaneously
Head position is used as spillway guide wall again, and flow condition is more complicated, therefore designs that a kind of structure is simple, safe and reliable panel
Rock-fill dams and spillway guide wall linked vector graph are extremely important.
Utility model content
Wall, which is led, with spillway the purpose of the utility model is to provide the rock for taking into account toe board and guide-wall connect knot
Structure.For this purpose, the utility model uses following technical scheme:
The rock and spillway for taking into account toe board and guide-wall lead wall connection structure, and the rock is provided with
Rockfill, panel, toe board, bulwark, spillway are side weir spillway, it is characterised in that:
Wall is led in side weir spillway and the setting of dam junction, the wall of leading is reinforced concrete structure, leads wall top two
Side includes two upper walls, wall wall wall and second on dam, first on spillway, second on first in two upper walls
Upper wall lower part shares a sole plate, and wall is linked together in upstream side on wall and second on first, leads wall downstream side and dam
Wave wall connects；
Wall is the guide-wall of spillway on first；
Wall sets toe of wall on second, and toe of wall is smoothly connect with dam toe slab, and toe of wall is also connect with dam face slab, also serve as dam with
The panel toe board of spillway joint area.
Further, wall uses irregular roundness arc form on described first, and 1~1.5m of top width, side is vertical near water, back
Water side slope degree 1:0.25~0.3.
Further, wall is a form of straight lines on described second, and wall is arranged close to dam side in 1~1.5m of top width
Toe, toe of wall 1.0~1.5m of top width, the toe of wall lower part gradient are delayed in 1:0.25, guarantee that stockpile grinding compacting, toe of wall line are toe board
" X " line.
Further, it is designed between toe of wall and panel as dam face slab periphery fissure.
Further, the spillway is side weir spillway, and side weir generally uses practical weir, and side weir spillway downstream side is set
Side channel is set, wall uses irregular roundness arc form on described first, is the guide-wall and side channel guide-wall of side weir spillway.
Further, on first on wall and second between wall there are space, wall on first, wall, bulwark surround on second
Region backfills rock ballast.
Due to using the technical solution of the utility model, the utility model is by being arranged a kind of spy between dam and spillway
Different form leads wall, forms overall structure with face dam, leads wall close to spillway side and play water guiding action, leads wall close to dam side
Play the role of plinth of concrete facing dam, above-mentioned type of attachment both ensure that flood releasing structure safety, and also increase dam water retaining structure
Safety.
Detailed description of the invention
Fig. 1 is the plan view of the utility model embodiment；
Fig. 2 is the A-A sectional view of the present embodiment.
Specific embodiment
Referring to attached drawing.The rock provided by the utility model for taking into account toe board and guide-wall is led wall with spillway and is connect
Structure, the concrete construction method and structure of the utility model are as follows:
The face plate rock-fill dam structure includes rockfill 10, panel 3, toe board 5, bulwark 4 etc..
The spillway is side weir spillway 2, and side channel 1 is arranged in 2 downstream side of side weir spillway, and the side weir spillway is general
Including side weir 2, side channel 1, control section, let out the structures such as slot, defrlector bucket.
The type of attachment of the rock and spillway is to lead wall, and leading wall is reinforced concrete structure, leads the upper of wall
Wall 7 on wall 6 and second is respectively set on first in portion two sides, and 7 lower part of wall shares a sole plate on wall 6 and second on first
100；Wall downstream side is led to connect with dam top bulwark 4.
Wall 6 is guide-wall close to spillway on first, and wall 6 is an irregular roundness arc form on first, if two sides are straight line,
Position of transferring uses circular sliding slopes, and 5m can be used in arc radius, has the function of good water guide, 1~1.5m of top width, near water
Side is vertical, land side gradient 1:0.25~0.3；
Wall 7 is a form of straight lines on second, and 1~1.5m of top width is arranged toe of wall 9 close to dam side, also serves as panel toe
Plate acts on, and the toe of wall 9 of wall 7 is used as dam face slab toe board on second, for the panel of face dam and spillway joint area structure
Arragement construction is more adaptable, and intensity is higher.7 inside gradient 1:0.25~0.3 of wall on second guarantees that stockpile 10 rolls
Closely knit, toe of wall 9 is smoothly connect with dam toe slab 5, and toe of wall 9 also serves as the toe board of dam face slab 3.Toe of wall line 8 is toe board " X " line, " X "
Line is the panel bottom surface elongated surfaces of face dam and the intersection of toe slab design foundation plane.On first on the back of wall 6 and second wall 7 it
Between there is space, the space having between wall 7 on first on wall 6 and second and bulwark 4 form enclosed area, can backfill rock ballast
11.The land side of wall 7 on back and second on first on the back of wall 6 and second with wall 6 on space, first between wall 7
With the gradient, project amount is not only greatly reduced in the space and the gradient, but also helps guarantee backfill material grinding compacting, improves toe of wall 9
Intensity.
The foregoing is merely the structure features of specific embodiment of the utility model, but the utility model to be not limited to
This, in the field of the utility model, made changes or modifications all cover practical new at this any those skilled in the art
Among the protection scope of type.
