Description
Technical field
The present invention relates to one and can monitor many materials associating seepage prevention system, belong to seepage control technique field.
Background technology
Pressure-seepage Flow on landslide, burst and collapse, play significant effect in the geological disaster such as mud-rock flow, process of osmosis not only corrosion has been taken away colloidal substance and fine grained in ground, has been caused it loose, also has the counter productives such as osmotic pressure promotes, floating holder, lubrication to Rock And Soil.International Commission on Large Dams (InternationalCommitteeonLargeDams) once carried out statistical analysis to global dykes and dams disaster of bursting, and thought that seepage abnormality is the main inducement of dykes and dams slump.Add up according to Chinese Water Conservancy portion, since having record from 1954, there are large dam breaking accident 3515 times in China, its Medium & Small Earth Rock Dam because of unrestrained top, seepage failure cause dam break accounting more than 98%, as dam breaks in succession such as Xinjiang connection abundance of water storehouse, Heilungkiang spark reservoir, Shanxi Qu Ting reservoirs in 2013, all cause significant casualties and economic loss.
Seepage control technique both domestic and external is similar so far, mainly comprises: filling grouting or curtain grouting, and based on various antiseepages (intercepting water) wall of concrete, clay, self-solidifying ash etc., high-pressure rotary-spray or pendulum sprinkling irrigation slurry, geomembrane or panel bedding, lid weight is oozed etc.In the process of antiseepage in nearly 40 years research, project team notices: due to conventional art anti-seepage scheme research, alternative time, all do not consider the mutual damage deterioration of constructional materials and carefully see evolving trend, cause dykes and dams and basis thereof after anti-seepage reinforcing or specific investment cost is too high or the impervious body life-span is too short, overall benefit is general very low, the maintenance fund of millions of ~ tens million of unit of each cost, but infiltration and antiskid index can only be made in several years to reach standard, far can not reach the designing requirement of economic life of a project (more than 50 years).Laterite (laterite) or claim admaic earth, extensively exists in damp and hot area of heavy rainfull, China mainly in Yunnan-Guizhou, Guangdong and Guangxi Provinces, the large area distribution of the provinces and regions such as Hainan.Laterite is faintly acid, the support substance mainly SiO of its physical mechanics

2deng.The recent research of project team shows: the alkaline reinforcement material such as cement, lime can not only occur to damage deterioration reaction mutually with silicon, iron, aluminium, titanyl compound in laterite, also can destroy the necessary acidic aqueous media of laterite cohesion, cause its particle destructing and material discrete, this uses traditional seepage control technique, the basic reason that its benefit is too low undoubtedly exactly on laterite ground and laterite class engineering.Construction and the reinforcing of seepage control project not only will consider the short-term factors such as investment, effect, also should pay attention to chemical degradation physical isolation etc. the long term factor of the deterioration differentiation under environmental activity of the interaction between material, microscopical structure, different materials contact surface, otherwise be not only difficult to effect a radical cure ubiquitous foreign material interface seepage disease, be more difficult to solve the difficult problems such as the cost performance of impervious body in medium and small project is too low, the normal cycle of operation of too high, the whole engineering of maintenance investment is too short.
Mainly concentrate in five in the research of impervious body association area both at home and abroad.(1) the particle of laterite develops and gradation design: scholars or analyzes the origin cause of formation of laterite, or the crumb structure of laterite is discussed and intercouples, or studies design and the grading analysis method of filter material, or probes into the impact of grain composition on degree of compaction ...(2) the seepage flow of foreign material contact interface is with stable: have scientific and technical personnel to have studied the mechanical property of contact interface, the frictional resistance that the larger material contacting surface of difference is then discussed had and shear property ...(3) antiseepage and reinforcing: have scholar to be conceived to the influence research of crack to clay cohesive force that seep water, or point bleed-native mechanism of action, or seepage prevention design method is discussed, or studies for the Performance Evaluation Technique of impervious body, or analyze the relation of reservoir level and phreatic line ...(4) relevant to construction technique: the scientific and technical personnel such as had have studied technique and the method for quality control of high-pressure injection, and what have has inquired into the reinforcement process of weak soil, what have then analyzes the material of impervious wall for simplifying construction technology ...(5) anti-seismic performance and index: have the relation of scholar to the impervious wall degree of depth and seismic stability to analyze, the dynamic characteristics of soil and liquefaction phenomenon when also having scholar to inquire into earthquake respectively ...The above-mentioned research in impervious body association area, is all emulation and the analysis of experiments conclusion of the aspect such as performance, application, reparation of carrying out for " single impervious material ", does not retrieve and combine the relevant research information of seepage prevention system to many materials.
In project of national nature science fund project (50869003, 41462013, 51069003), Yunnan Province's applied basic research plan key project (2013FA033), Yunnan Province Natural Science Fund In The Light (1991E016Q, 1995YI016, 1997E047M, 2010ZC048), and education department of Yunnan Province (10968221, 10978057), innovation team of Kunming University of Science and Technology (14098193), under Classic Course (10968137) etc. are repeatedly set up the project and are subsidized, this project team is thought through studying for a long period of time, the impervious body using homogenous material to form all also exists obvious life-span defect: earth core, the dependence of sloping core commute corrosion grain composition is very large, anti-seepage effect is poor, and the felt earthquake of lower earthquake intensity will cause lax segregation or fracture, the materials such as concrete, lime, self-solidifying ash belong to strong alkaline substance, its impervious wall formed not only cost and technical requirements high, and can with the laterite main body generation chemical reaction of acidity and destroy contact interface, cause a large amount of trickle piping, geomembrane is too thin, is not only difficult to resist vegeto-animal the biting of many decades and tears, more built on stilts after the film that after being more difficult to adapt to consolidation, earthquake, the differential settlement of laterite is formed ...Therefore, the effective intensive monitoring of large area is implemented to impervious body and to adopt multiple material to carry out associating antiseepage imperative.The improper deterioration factor of laterite impervious body has been understood fully by this project team, know the erosion of the highly basic such as cement to laterite material, proposing traditional impervious body, to reprocess the phase too short, be difficult to the root reaching projected life, distinct comparatively long-term material damages evolution mechanism mutually, invent optical fiber geomembrane and obtained 3 licenses, more research paper is at " geotechnical engineering journal ", " Chinese Journal of Rock Mechanics and Engineering ", " Journal of Building Materials ", " hydroelectric generation journal ", " AdvancedMaterialsResearch ", " AppliedMechanicsandMaterials " etc. domestic and international authoritative journal is delivered, and by SCI, the internationally famous searching mechanism such as EI is included.Achievement in research shows: antiseepage antiskid technology and the reinforcement material of laterite ground and dykes and dams employing so far all exist obvious shortcoming, combine erosion for a long time due to factors such as chemical reaction, mechanics effect, soil-water interaction, these defects only rely on the traditional measures such as material sieves, structure rolls, anti-filter draining, reinforcement filling obviously all cannot effect a radical cure.In fact, repeatedly Reinforcement is carried out to impervious body in the short period, in many laterite engineerings, cause huge waste, and define the bottleneck that development is continued in this field of restriction.Therefore, research not only has respective strengths but also can resist environmental attack, is convenient to many materials of large area intensive monitoring associating seepage prevention systems, has become very urgent task.For this this project team applies for and got permission project of national nature science fund project for 2014 specially: the antiseepage new model that seepage flow brings out laterite landslide is explored, project approval number: 41462013.
Traditional various antiseepage antiskid technology, its common defects can be summed up as: 1. traditional impervious body exists open defect, can not bear the long-term erosion of environment water and soil, therefore far can not reach projected life; 2. there is major defect in anti-seepage reinforcing material, and the acidic rock soil bodys such as itself and laterite destroy mutually, is the root causing dykes and dams and basis thereof repeatedly to keep in repair, repair and more leak, bring out side slope slump and dam break in a short time; 3. the impervious body of bedding and grouting formation is thinner, easily occur fracture when felt earthquake, and the development of seepage failure is very fast; 4. the existing monitoring facilities imperfection of impervious body, the spacing that sensor is arranged is too large and too poor with the compatibility of impervious body.Various environmental attack all develops from outside to inside gradually, if can by traditional impervious body and corrosive deposit isolated, then long-term erosion problem can be readily solved.Geomembrane belongs to cheap acid and alkali-resistance flexible corrosion protection material, and except having easy construction, repairing the advantages such as quick, its durability has also exceeded the design economic life of Tu Shidiba.The major defect of geomembrane is: (1) intensity is too low, and whether the planeness of bed course and stability determine geomembrane to a great extent long-lived; (2) can not determine the damaged part of dykes and dams inside in time, will valuable speedily carrying out rescue work the time be lost thus.
Aforementioned (1) individual problem, optional with there is high strength and can adapt to earth-structure deformation drag transition material---carbon cloth solves.Carbon cloth is a kind of high-strength flexible material of relative low price, and its tensile strength>=3200MPa, higher than steel; Proportion 2.0 ~ 3.0g/cm
3, less than the half of steel; Minimum thickness is about 0.2mm only.This material acid-alkali-corrosive-resisting, resistance to wear and pierce through, being suitable for being on active service for a long time in adverse circumstances; Can cut out arbitrarily, be easy to overlap joint bonding, and differential settlement or the consolidation deformation of Rock And Soil can be adapted to, be widely used among construction work at present.Aforesaid (2) individual key technology, seminar obtains substantial progress in the project of concluding, has delivered related ends, has got permission the patent for invention of " optical fiber geomembrane ", can realize the intensive monitoring of real-time large area of impervious body.
Earthquake and long-term seepage very easily make laterite class ground and dykes and dams occur, and crack, inside are built on stilts.The anti-seepage scheme of the present invention's design is: using clay or concrete as built-in posting body, the various loads transmitted in impervious face pass to agent structure; Keep the post-rift basic body of posting body and posting function with carbon cloth, and provide even drag and smooth bed course for geomembrane; Using optical fiber geomembrane impervious and as monitoring carrier.The associating antidetonation seepage prevention system of triplicity and excellent, and various load assignment is passed to the carrying main body of engineering.The optical fiber geomembrane adopted in this invention is not only the carrier of the intensive monitoring of large area, also solves the ubiquitous difficult problem corroded with other material interface of traditional impervious body as separation layer.In water vegeto-animal bite to tear resisted by the carbon cloth of high strength; Built-in posting body not only gives geomembrane with suitable planar support and load transmission, also will bear the setting task of facade antiseepage.If there is inner built on stilts or fracture in posting body, by by high strength and the carbon cloth of flexibility automatically adjust its basic configuration with adapt to basis or dykes and dams main body, guarantee its load transmission effect.As the drag protection bed course of geomembrane, carbon cloth is also by the effect playing uniform load, avoid stress to concentrate.Therefore, many material associating seepage prevention systems of this novelty can avoid the erosion generally occurred so far, built on stilts, brittle failure, leach, tear, spread etc. disease development.
The present invention is by project of national nature science fund project (50869003,41462013,51069003), research is subsidized in Yunnan Province's applied basic research plans key project (2013FA033) etc., stress to solve the fracture of traditional impervious body or inner built on stilts after resistance ooze inefficacy, seepage flow and sharply worsen and bring out that ground comes down, the difficult problem such as to cave in, and can significantly reduce leakage, long term monitoring seepage flow evolution, make a definite diagnosis the disease position of seepage prevention system.The seepage prevention system not only shock-proof durable that the present invention proposes, and location, sick danger accurately can be provided for abnormal seepage flow improvement, speedily carry out rescue work for geological disaster and save the time of preciousness.

In the present invention, the function of each important composition is:
(1) built-in posting body: make according to existing core-wall specification with clay or concrete, its major function is that the various loads transmitted in impervious face pass to the agent structure such as dam shell, basis.Secondly, built-in posting body can also give geomembrane with suitable planar support and bear the setting task of facade impervious body.
(2) integument: cut out with carbon cloth or gauze wire cloth or geotextile and cohere (welding) and make, the external surface of the built-in posting body of parcel comprehensively.Its predominant use be ensure the fracture of posting body, inner built on stilts after basic body and load propagation function, and automatically adapt to the distortion of posting body, for geomembrane provides uniform counter-force and smooth bed course.If there is inner built on stilts or fracture in posting body, by by high strength and the integument of flexibility automatically adjust its basic configuration with adapt to basis or dykes and dams main body, guarantee its load transmission effect.
(3) impervious monitor layer: cut out to cohere with the optical fiber geomembrane of patented mandate and make, the seepage flow being only placed in impervious body carrys out source, upstream face coated carbon cloth.Its major function significantly reduces leakage, and carry out long-term intensive monitoring to seepage flow.Optical fiber geomembrane is not only impervious and carrier that the is intensive monitoring of large area, also solves the ubiquitous difficult problem corroded with other material interface of traditional impervious body as separation layer.In water, vegeto-animal biting is torn, and is resisted by the carbon cloth of high strength.
Operating principle of the present invention:
The Major Diseases of tradition impervious body comprises: material corrosion, inner built on stilts, fracture, and particle leaches, impervious weak effect, and failure stress is concentrated, lack effectively monitoring etc., refers to the elaboration in " background technology ".
(1) the present invention adopts high strength and " integument " of flexibility, and in order to solve, above-mentioned inside is built on stilts, fracture, the difficult problems such as particle leaches, failure stress is concentrated.Core-wall generally to use in dykes and dams: traditional core-wall usually rolls with clay filling and forms, under the long term of Pressure-seepage Flow, soil particle corrosion leaches, core-wall inside built on stilts inevitable, if reinforce not in time, easily develop into and collapse; Under the effect of larger earthquake load, core-wall is easy to fracture, and seepage flow sharply worsens, if speedily carry out rescue work will cause dam break not in time.In the present invention, traditional core-wall (as shown in Figure 4) is only used as the posting body in novel associating seepage prevention system, and is no longer antiseepage main body, and therefore it ruptures, collapsing all to cause seepage flow to worsen; The integument of high strength constrains the distortion of core-wall, make it leach at particle, change in shape after inner built on stilts, fracture significantly reduces, in addition the integument in body series and impervious monitor layer are all flexible, automatically can adjust shape to adapt to the small deformation of posting body, effectively prevent stress and concentrate.Therefore the anti-permeability performance of this invention is substantially not built on stilts by above-mentioned inside, fracture, the impact of the diseases such as particle leaches, stress is concentrated, obviously extends the bulk life time of seepage control project.
(2) the present invention adopts " impervious monitor layer ", in order to solve above-mentioned impervious weak effect, the difficult problem such as particle corrosion leaches, material corrosion.Achievement in research shows: the transmission coefficient of earth core is generally 10
-4~ 10
-7cm/s, and the impervious main body that the present invention adopts is optical fiber geomembrane, its transmission coefficient is only 10
-11~ 10
-12cm/s, therefore its impervious Be very effective improve, greatly reduce film after osmotic pressure and seepage discharge, and then effectively reduce the corrosion passing carrier granular and leach.Parcel, impervious while, the material of posting body and dam shell, basis etc. are also kept apart by optical fiber geomembrane and carbon cloth comprehensively, thus avoid impervious body and other material generation interracial contact corrodes, and obviously extend the life-span of engineering.
(3) the present invention adopts " impervious monitor layer ", in order to solve a difficult problem for above-mentioned effective monitoring.Tradition impervious body is limited to cost and the disturbance of probe to entirety, and the quantity of sensor is tangible very little, the life-span is too short, is difficult to carry out effective and long-term monitoring for the development of seepage flow and deterioration.The monitoring main body adopted in the present invention is optical fiber geomembrane, using distribution type fiber-optic wherein as intensive sensor, this novel sensor is corrosion-resistant, the life-span is long, can temperature, the STRESS VARIATION of each point in long term monitoring geomembrane, and using " temperature comparisons is abnormal " and " stress contrast is abnormal " breaks as geomembrane, seepage flow worsens judgment basis.To concentrative seepage be there is in the damaged part of geomembrane, obvious difference is all had before the flowing of water body causes temperature herein, stress and breakage, with neighbouring unbroken position, extremely can be determined the damage location of geomembrane by the contrast of time domain, territory, face monitored data, refer to the optical fiber geomembrane patent of invention manual (ZL201010109990.4 of granting authorization; ZL201010109987.2).
The invention has the beneficial effects as follows:
(1) difficult problem that traditional impervious body sharply worsens at fracture, inner built on stilts rear seepage flow is solved
Tradition impervious body very easily ruptures under seismic load; Under the long-term corrosion of Pressure-seepage Flow, impervious body inside cannot avoid thin sight to make somebody a mere figurehead.Tradition impervious body fracture or inner built on stilts after seepage discharge obviously strengthen, the piping caused thus, draw brush and passing and make crack and built on stiltsly sharply to expand, cause Rock And Soil come down or cave in.
In the seepage prevention system that the present invention proposes, traditional impervious body does not only use as impervious body as posting body, and therefore it ruptures or make somebody a mere figurehead and all can not change seepage discharge.Integument in the present invention and impervious monitor layer are flexible material, in posting body fracture, inner built on stilts and even after caving in, can both adaptive deformation automatically, significantly reduce the outflow of particle, and can maintain transmit load basic body, avoid stress to concentrate, just effectively prevent thus seepage flow disease development and worsen.
(2) prevent animals and plants to the destruction of impervious body
Clay class, the growth of geomembrane quasi-tradition impervious body to plant pierce through, the biting to tear and all lack defence capability of animal, and this is also the major reason that traditional impervious body wrecks.Assembled scheme in the present invention adopts the carbon cloth of high strength or gauze wire cloth or geotextile as complete surperficial integument, effectively can resist the destruction of various concentrated stress to impervious body.
(3) impervious body has been blocked and the mutual of other material damages deterioration
Concrete, pozzolan, self-solidifying ash class impervious body all belongs to basic matterial, with the laterite dykes and dams major ingredient of acidity, long-term chemical reaction occurs, and product is solvable or be powdery, is very easily taken away by Pressure-seepage Flow, thus causes traditional impervious body that the diseases such as thin sight piping occur.The present invention adopts corrosion resistant integument and impervious monitor layer, and posting body and dykes and dams major ingredient are effectively kept apart, and greatly reduces the mutual erosion of material.
(4) permanently effective monitoring can be implemented to seepage flow
Adopt in the present invention impervious monitor layer be the optical fiber geomembrane having obtained 3 patents for invention, utilize optical fiber sensing technology and relevant spectral theory, all can realize long-term intensive Quantitative Monitoring to seepage discharge and sudden change thereof.Therefore, this impervious body can early warning seepage flow disease, the ground landslide that the abnormal seepage flow of effective strick precaution causes or the routed disaster of collapsing of dykes and dams.
(5) position of disease can be made a definite diagnosis
After disease appears in tradition impervious body, can only revolve according to the water of dykes and dams upstream and flow out with the water in downstream the position that ease point roughly judges disease.But due to reasons such as the crack of each layer of dykes and dams are not corresponding, seepage flow spreads in dam material, the error of this disease location is very large, and the cost that often can only expend several times and even decades of times carries out general impermeable management.Temperature, the stress at seepage abnormality position are all obvious with the difference of normal portions, this combines in impervious system the sudden change that the impervious monitor layer adopted can predict each point temperature, stress, therefore, it is possible to make a definite diagnosis the position of disease, thus save considerably piping or native the speedily carrying out rescue work the time of stream.
(6) construction costs, disaster reduction and prevention is saved
Seepage failure is the dangerous condition of dykes and dams and causes the main reason of collapsing of bursting, and China is the country that maximum, the sick dangerous section's journey of dykes and dams quantity is maximum in the world, and government all takes out the reinforcement of nearly hundred billion funds for various dash, antiseepage every year.Many material associating seepage prevention systems that this invention proposes can avoid the material corrosion generally occurred, inner built on stilts, fracture, the sick dangers such as particle leaches, seepage flow sharply spreads, and the seepage abnormality position of impervious body can be located rapidly and exactly, save valuable time of speedily carrying out rescue work and reinforcing expense.Its application category will obtain rapid expansion, replaces the expensive structure such as high pressure jet grouting, concrete cut gradually, thus produces significant economic benefit under the premise that security is guaranteed.This technology for improving the security performance of retaining works, the cost performance improving impervious body, the reinforcement expense etc. of obviously saving dykes and dams be all of great importance, and effectively can reduce dykes and dams and to burst the generation of disaster of collapsing.
