Description
Technical field
The utility model relates to a kind of hydraulic engineering structure, especially a kind of dam body seepage structure.
Background technique
A large amount of dangerously weak reseroirs are currently, there are, of the remote past due to building, execution conditions are poor, and there are more quality to ask
Topic, especially dam body, leakage of dam foundation are serious, and reservoir is difficult to water storage, and can not bring into normal play benefit, need to carry out antiseepage.
The technology for being currently used for dam body seepage includes grout curtain, concrete cut, high pressure jet grouting etc.；Curtain fills
Slurry is used for dam body seepage construction is simple, but grout curtain can only fill the intracorporal hole in dam, and effect is poor；Using concrete anti-seepage
Wall, complicated construction technique need biggish operation platform, and concrete cut and former dam body conjugation are poor；High-pressure injection
Grouting, needs high-tension apparatus, difficulty of construction is big, and more demanding to ground, lower at wall rate.
Utility model content
The goal of the invention of the utility model is: in view of the above problems, providing a kind of dam body seepage structure, solves
The problem of anti-seepage effect present in former seepage control of dam is poor, cut-pff wall and former dam body conjugation are poor, and difficulty of construction is big, dam is anti-
Infiltration effect is obvious.
The technical solution adopted in the utility model is as follows:
A kind of embankment seepage preventing structure of the utility model including the interior cut-pff wall being set in dam body, and is arranged in dam body
Inner wall surface outer cut-pff wall；The outer cut-pff wall includes the company on the impervious barrier and interior wall horizontal plane on interior wall inclined-plane
Connect layer；Impervious barrier and interior cut-pff wall are connected by the articulamentum；The interior cut-pff wall is constituted by stirring stake deeply.
The above structure, the utility model solve single layer cut-pff wall anti-seepage effect difference by the setting of inside and outside cut-pff wall
Problem；The setting of articulamentum simultaneously, impervious barrier and interior cut-pff wall are connected, and solve cut-pff wall and former dam body conjugation is poor
The problem of, in this configuration, stake is stirred since interior cut-pff wall is arranged in dam body, and using deep, stability is fine, connects antiseepage
After layer, the movement of impervious barrier can be limited, preferably in conjunction with dam body.
Preferably, the interior cut-pff wall includes that several depths stir stake, stir between stake and partly overlap deeply, stirs stake deeply and combine company
At wall.
The above structure is applied the cut-pff wall for stirring stake composition deeply on dam body, construction is simple, compared with list higher at wall rate
Only impervious barrier stability is good, good seepage-proof property, and to the effect of the right reinforcing of dam body, can also improve the antiseepage effect of entire dam body
Fruit.
Preferably, the impervious barrier is successively arranged low pressure impervious barrier, middle pressure impervious barrier and high pressure impervious barrier from top to bottom；
The thickness of the low pressure impervious barrier is less than the thickness of middle pressure impervious barrier, and the thickness of middle pressure impervious barrier is less than the thickness of high pressure impervious barrier
Degree.
The above structure, different water layers brings infiltration possibility caused by different hydraulic pressure different, but traditional antiseepage
Layer is uniform thickness, and when the impervious barrier when upper layer reaches requirement, the impervious barrier of possible lower layer is unable to satisfy requirement, different antiseepages
The design of layer can satisfy the requirement of different water levels, guarantee anti-seepage effect；It is able to maintain the penetration of dam body different location simultaneously
Balance avoids the excessive damage of impervious barrier compression, ineffective.
Preferably, the impervious barrier is outer arcuate structure, the thickness of impervious barrier is gradually reduced from centre to both sides.
The above structure is from top to bottom linear construction, but dam body is not since traditional seepage-proof dip dire uses plane
It is different with the effect of antiseepage is needed with pressure suffered by position, by using outer arcuate structure, antiseepage thickness among dam body, two
The impervious barrier on side is relatively thin, can be suitable for the actual conditions of dam body, increase horizontal and vertical anti-seepage effect.
Preferably, layout is equipped with perfusion channel in the impervious barrier, the bottom and side wall of perfusion channel is equipped with perfusion
Hole.
The above structure, the setting of perfusion channel can reduce the difficulty of construction of impervious barrier, not need to need as traditional perfusion
Want construction personnel reach dam bottom, be in the milk after one layer, then upward grouting of being in the milk, construction personnel needs dam body different location into
Row grouting；And in this structure, it is only necessary to it is perfused downwards from dam crest, reduces the security risk of construction, it is easy to operate, simultaneously
It can construct on different dam bodys.
Preferably, the fill orifice is connected to each impervious barrier.
The above structure, the slurries in perfusion channel are entered in each impervious barrier by fill orifice, after lower layer's grouting is full, slurry
Liquid enters upper layer, and gradually perfusion upwards, completes the grouting of each impervious barrier from the bottom up.
Preferably, the perfusion channel and fill orifice are steel construction.
The above structure, steel construction can guarantee the intensity of perfusion channel and fill orifice, pass through slurries, improve perfusion
Efficiency.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, good seepage-proof property, the design of two-layer barrier layer, and the deep setting for stirring a cut-pff wall, solve existing antiseepage side
The poor problem of method anti-seepage effect, improves anti-seepage effect.
2, construction is simple, construction personnel are in the milk downwards by perfusion channel, and slurries are completed automatically into different impervious barriers
Perfusion, it is easy to operate.
