Specific embodiment
As shown in Figures 1 to 4, the utility model includes the N sections of oblique horses for being sequentially connected and being arranged by cutting slope into dam body
Road 5, N sections of oblique riding tracks 5 form the oblique riding tracks of "the" shape, wherein N is the positive integer not less than 2, between two neighboring oblique riding track 5
It is provided with the road surface Shuan Po 6, the road surface Shuan Po 6 is connected to dam abutment gutter 8.
It should be noted that tailings reservoir preliminary dam guarantees that the width of initial dam dam crest 1 is greater than the width and entirety of oblique riding track 5
The gradient is constant, and the width of preferred initial dam dam crest 1 is 6m, will be original on the basis of former dam body outer contour 2 when practical operation
Patch slope mode change and the oblique riding track of "the" shape is set inwardly to cut the mode on slope also serves as initial dam permanently upper dam road, part is adjusted
It is whole that the gradient of original 1:2.0 is adjusted to the gradient of 1:1.75 from oblique riding track 5 to the dam facing gradient of 1 part of initial dam dam crest,
In Fig. 1 dam body patch slope outer contour 4 be to paste the dam body outer contour that oblique riding track is arranged in a manner of slope and is formed, as height rises,
Oblique riding track width is opposite to narrow, and such mode easily largely increases cubic metre of earth and stone dosage；In Fig. 1 dam body cut slope outer contour 3 be with
It inside cuts slope mode and the dam body outer contour that oblique riding track is formed is set, the dosage that such mode increases the cubic metre of earth and stone far smaller than pastes slope side
The increased cubic metre of earth and stone dosage of formula, effectively cuts down expenses.
In the present embodiment, the longitudinal slope mean inclination of the oblique riding track 5 is 8%, and the horizontal slope mean inclination of the oblique riding track 5 is
2% and single slope introversion.
In the present embodiment, the gradient on the road surface Shuan Po 6 is 2%~3%.
It should be noted that inwardly cutting the slope setting oblique riding track of "the" shape, office on the basis of former dam body cross-sectional outer profile
Portion adjusts the dam facing gradient, and coefficient is rolled inside raising dam body ensures the safety and stability of dam body, and oblique 5 straightway of riding track is vertical by road surface
Slope draining does not set gutter, and the oblique turning of riding track 5 junction sets the road surface Shuan Po 6 and completes draining, and a slope is complete with oblique riding track road surface longitudinal slope
At draining, another slope slope aspect dam abutment gutter 8, to constitute the drainage system of entire dam facing, reliable and stable, using effect is good.
In the present embodiment, the width of the oblique riding track 5 is not less than 5m, and tiltedly riding track 5 be equipped with far from the side of dam body it is anti-
Guardrail 9.
In the present embodiment, with the connection of 1:1.75 slope surface between the two neighboring oblique riding track 5.
In the present embodiment, the most narrow width and length on the road surface Shuan Po 6 are not less than 12m.
It should be noted that the purpose one that the most narrow width and length on the road surface Shuan Po 6 are not less than 12m is easy for largely
Draining, second is that for the ease of the meeting of vehicle on dam, securely and reliably.
In the present embodiment, the oblique riding track 5 includes bottom and the concrete topping positioned at the bottom upper surface.
The utility model is suitable for the situation that mountain valley-type Tailings Dam topography complicated construction is limited, wide with former dam body cross-sectional outer
The slope setting oblique riding track of "the" shape, the local directed complete set dam facing gradient are inwardly cut on the basis of line, oblique riding track straightway passes through road surface longitudinal slope
Draining, oblique riding track turning junction set the road surface Shuan Po and complete draining, not only can guarantee the safety and stability of dam body, but also be avoided that dam is outside upper
Dam road reduces difficulty of construction because of construction problems such as landform reason bring massif explosions, reduces the destruction to ecological environment, and
It is huge to overcome earthwork volume caused by conventional slope sticking type road, the shortcomings that claim for eot, effectively save spending.
The above is only the preferred embodiment of the utility model, not imposes any restrictions to the utility model, all
According to any simple modification to the above embodiments of the utility model technical spirit, change and equivalent structural changes, still
Belong in the protection scope of technical solutions of the utility model.
