Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: a kind of dam body resistance to deformation leakage preventing structure, with reference to Fig. 1, including dam body 2, dam body 2 is towards the side of rubbish heap
Block is connected to protective fence 9, and protective fence 9 is higher by the top planes of dam body 2.What is formed between dam body 2 and hillside is similar to the recessed of mountain valley
Be embedded with a large amount of rubbish in slot, rubbish formed rubbish to and degenerate and generate the liquid of black, when dam body 2 bears not living rubbish heap
Gravity when, crack can be generated on dam body 2, the liquid of black continues to leak into dam body 2 along crack at this time, so that dam body 2
Easily collapse.
With reference to Fig. 1, in order to improve the leak preventing effect of dam body 2, operator is when building dam body 2, along the vertical side of dam body 2
To being embedded with dual pipe high-pressure rotary jet grouting pile 1, and it is embedded with mini-valve tube in dam body 2 and in the side of dual pipe high-pressure rotary jet grouting pile 1,
It is equipped with a grout outlet every 50 centimeters along the vertical direction on the side wall of mini-valve tube, cement mortar is perfused operator when construction
Into mini-valve tube, part of cement mortar is sprayed from grout outlet and is adhered on dual pipe high-pressure rotary jet grouting pile 1 in dam body 2, is increased
Whole integrality, formed after cement mortar solidification sleeve valve barrel grouting stake 3 be collectively formed with dual pipe high-pressure rotary jet grouting pile 1 it is anti-
Wall is seeped, the rubbish liquid for reducing black continues the possibility permeated towards in dam body 2.In the construction process, it is being easy to happen infiltration
The place of leakage is embedded with double dual pipe high-pressure rotary jet grouting pile 1 and double sleeve valve barrel grouting stake 3, plays the effect of dual antiseep
Fruit.
It buries and builds along slopes with reference to Fig. 1, in dam body 2 and be connected to concrete anti-seepage plate 4, concrete anti-seepage plate 4 and slopes
Keeping parallelism.Support column 7 is embedded in the slopes of dam body 2, support column 7 is vertically arranged in slopes, and support column 7 is anti-towards concrete
The one end for seeping plate 4, which is built, to be connect on being supported on concrete anti-seepage plate 4.The setting of concrete anti-seepage plate 4, when reducing rainy rainwater from
Slopes penetrate into the possibility for making the structure of dam body 2 collapse in dam body 2, while support column 7 plays concrete anti-seepage plate 4
The effect of support plays the role of overall structure to stablize support.The lower section of the slopes of dam body 2 is equipped with a reservoir 6,
When raining, rainwater flows in reservoir 6 along the slope surface of dam body 2, is equipped with french drain in the lower section of concrete anti-seepage plate 4 in dam body 2
5, french drain 5 is connected with reservoir 6, and french drain 5 is embedded in dam body 2, can when the black liquor that rubbish generates penetrates into dam body 2
To flow in reservoir 6 by french drain 5, the channel of flowing is provided to liquid, reduces liquid and permeate to flow in dam body 2 and lead
Cause the possibility that structure deforms and dam body 2 is collapsed in dam body 2.
With reference to Fig. 1, multiple anchoring piles 8 have been thrown in dam body 2 into, multiple anchoring piles 8 are equal along the length direction of concrete anti-seepage plate 4
Even distribution.Anchoring pile 8 connects towards one end of concrete anti-seepage plate 4 and the side concrete block of concrete anti-seepage plate 4 towards french drain 5
Together, and anchoring pile 8 with concrete anti-seepage plate 4 keeps vertical.Dam body 2 is anchored by anchoring pile 8, to the whole of dam body 2
Body structure plays reinforcement effect, the internal structure for reducing dam body 2 when dam body 2 leaks deform and collapse can
Energy.
Action process: when dam body 2 leaks, double dual pipe high-pressure rotary jet grouting pile 1 and double sleeve valve barrel grouting stake 3
The cut-pff wall of formation separates the flow direction for the black liquor that rubbish generates, and that reduces that liquid continues to leak into dam body 2 can
Can, it is flowed in reservoir 6 when liquid continues leakage in dam body 2 by french drain 5.During dam body 2 leaks, anchor
Bolt, support column 7 and concrete anti-seepage plate 4 all play the role of reinforcing to dam body 2, reduce dam body 2 and deform and collapse
The possibility collapsed.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
