Abstract
The invention discloses one kind to mix rubber antidetonation earth and rockfill dam and its design and construction method；It is described mix rubber antidetonation earth and rockfill dam dam body by stockpile, mix rubber stockpile, core-wall or panel and form.Replace part partial size stockpile by waste tire rubber particle, constitutes " damper " of earth and rockfill dam.Flexible deformation, which occurs, for the rubber grain filled under high pressure, geological process reduces the effective stress of earth and rockfill dam, mitigates the broken of stockpile and achievees the purpose that shock-resistant and energy-dissipating reduces earthquake permanent deformation.The invention also discloses the above-mentioned design and construction methods for mixing rubber antidetonation earth and rockfill dam；The earth and rockfill dam built using this method, raw material are conveniently easy to get, advantageously reduce project cost, greatly improve the shock resistance of earth and rockfill dam, have good social and economic benefits.
Description
Technical field
It is specifically a kind of to mix rubber antidetonation earth and rockfill dam and its design and construction side the present invention relates to hydraulic engineering technical field
Method.
Background technique
Under the background of global warming, replace traditional energy imperative using new energy.Water energy is that cleaning can the energy again
It is considered as the important channel for substituting fossil energy construction low-carbon economy.The water energy in 80% or more China is located at west area, but
It is that west area geological disaster is frequent, it is huge builds earth and rockfill dam investment, pole is caused to country and the downstream people once dam break occurs
Big loss.The earth and rockfill dam Seismic Resistance And Disaster Reduction measure that geological disaster especially earthquake is resisted in research has great society and economic meaning
Justice.
Earth and rockfill dam obtains biggish dry density in process of construction and usually requires that stockpile gradation is good or so-called
" fractal curve " gradation.This gradation requires the integrality for being conducive to keep particle under earthquake, the contour energy load action of explosion
But it is unfavorable for dissipation of energy, be easy to cause entirety brokenization of dam body.The broken energy dissipating for being conducive to dam body of stockpile, but particle
The broken large particle size filler for occurring often in disproportionately graded, if be easy to causeing the seepage failure of dam body using such gradation.Work
Structural measure in journey for antidetonation is most widely used and successfully surely belongs to damper, is different from the rod pieces such as bridge skyscraper
System, earth and rockfill dam belong to the structures for coming into contact in a large area stress, and traditional damper cannot be used for the antidetonation of earth and rockfill dam.
The reduction of pliability rigidity of dam body is mainly improved by the methods of reinforcement or high polymer grouting in the prior art
Antidetonation is realized in measure, these methods require slip casting and increase difficulty of construction, and high polymer is easy degradation with aging, production
Process also easily generates adverse effect to environment.
Summary of the invention
Present invention aim to address difficulty of construction is big in the prior art, high polymer be easy degradation with aging, be unfavorable for protecting
The problems such as environment.
To realize the present invention purpose and the technical solution adopted is that such, one kind mixing rubber antidetonation earth and rockfill dam, including mixes
Rubber earth rockfill dam with central core, it is characterised in that: including core-wall, mix rubber stockpile, stockpile and rubber grain；
The section for mixing rubber earth rockfill dam with central core is trapezoidal；It mixes at the half height of rubber earth rockfill dam with central core for boundary
Line, the top in the line of demarcation be stockpile pile up form, lower section is to mix rubber stockpile and pile up；
The rubber stockpile of mixing is the mixture that rubber grain and stockpile are constituted；
The center position for mixing rubber earth rockfill dam with central core is equipped with core-wall.
One kind mixing rubber antidetonation earth and rockfill dam, including mixes rubber panel earth and rockfill dam, it is characterised in that: including mixing rubber enrockment
Material, stockpile, panel and rubber grain；
The section of rubber panel earth and rockfill dam is mixed at trapezoidal；The line of symmetry for mixing the upstream and downstream of rubber panel earth and rockfill dam is point
Boundary line；The upstream side be mix rubber stockpile pile up form, downstream side is that stockpile is piled up；
The rubber stockpile of mixing is the mixture that rubber grain and stockpile are constituted；
The upstream outer surface for mixing rubber panel earth and rockfill dam is equipped with panel.
A kind of design and construction method for mixing rubber antidetonation earth and rockfill dam, which comprises the following steps:
1) reasonable material source is chosen after exploring environment；
2) stock ground stockpile field compaction test is carried out, determines, design and choose reasonable stockpile gradation, grade is drawn and writes music for a song
Line；
3) it removes in grading curve obtained in step 2), 10% or less the percentage of small Mr. Yu's partial size, 30~35%, 50
~55% stockpile；
4) stockpile of the rubber grain substitution removal of the quality such as use；
Obtain the mass ratio of stockpile and rubber grain, the rubber grain of formation and the curve of stockpile；
5) by the stockpile in large-scale screening system removal step 3), the rubber grain in step 4), mix dress is added
Material；
6) it carries out rolling experiment, determines the relevant parameter of maximum compactive effort, layer thickness, optimum moisture content, pass through routine
Dam filling construction carries out stone and rolls.
Further, the rubber grain is the product obtained after waste tire crushes；The partial size of the rubber grain is less than
10mm。
Further, the material of the core-wall is pitch or clay.
Further, the material of the panel is concrete.
The solution have the advantages that unquestionable, the invention has the following advantages that
1) energy that earthquake cyclic load generates dam body can be effectively absorbed, substitution stockpile 3 is crushed energy dissipating mechanism, from
And Particle Breakage is prevented, reduce earthquake permanent deformation.
2) the annual waste tire in China is a plurality of up to 500,000,000, and as burned, production rubber powder etc. can all produce environment conventional recovery methods
Raw certain pollution, the present invention provide a kind of pollution-free damaged tire Disposal Measures.
3) similar with gravel core wall construction method is mixed, using conventional construction method, additional construction machinery is not needed, it will not
Increase construction cost.The usage amount that stockpile can be reduced simultaneously, which is saved, excavates cost.
4) rubber grain added is smaller, is filled in stockpile hole, avoids pressure and builds not firm, dry density, which is not achieved, to be wanted
The case where asking.
