Description
Technical field
The invention belongs to the infrastructure anti-seepage reinforcing technical fields such as water conservancy, mine, environmental protection, the high polymer hoisting grouting method using while being specifically related to the anti-seepage reinforcings such as earth embankment, earth dam, tailing dam, section dirty dam.
Background technology
Since founding of New, the infrastructure constructions such as the water conservancy of China, mine, environmental protection have obtained the economic growth and social progress of remarkable achievement ，Dui China and have brought into play important function.Aspect water resource infrastructure construction, because the most water conservancy projectss of China are built last century 50 to the seventies, be limited to economic technology condition at that time, many Design of Reservoirs and construction quality " inadequate natural endowment ".Through long-term operation, long neglected and in disrepair, aging serious, sick dangerous problem is very outstanding.At present, the built all kinds of reservoirs of China reach 8.7 ten thousand, occupy first place in the world.But approximately 40% small reservoir, 25% big-and-middle-sized reservoir belong to dangerously weak reseroirs, people's lives and properties and social stability are formed to great threat.China dyke is built with a long history, but mostly through heightening and thickening gradually over the years, forms, and levee body fills soil and mostly is different times and fetches earth on the spot, fills quality nearly less than designing requirement, has different potential safety hazards.In existing more than 40,000 dangerously weak reseroirs of China, more than 90% be earth and rockfill dam, and most dyke is soil property dyke.According to initial estimate, approximately more than 50% small-sized dangerously weak reseroirs need to carry out anti-seepage reinforcing.Aspect the infrastructure of mine, the key facility that tailing dam is produced as mine ore dressing, it is that accident is easily sent out position, is also the dangerous matter sources of latent huge potential safety hazard.In addition, also contain various poisonous and harmful substances in Tailings Dam, and be a kind of artificial debris flow formation region with high potential energy, its safe operation is directly connected to the ecological environment of downstream the people's lives and property safety and surrounding area, reservoir area.In the many Tailings Dams in China mine, the current less than 70% in normal operation, some industries surpass 40% Tailings Dam in dangerous, sick, the service state of exceeding the time limit, and Tailings Dam major accident happens occasionally.And seepage is as the one of the main reasons of tailing dam accident, how effectively administers seepage and guarantee that Safety of Tailings Dam operation seems very urgent and important.Aspect Environmental Protection Infrastructure construction, according to statistics, in the existing refuse landfill of China, simple and easy landfill and accurate sanitary landfills account for more than 95% at present.Because most of landfill yards do not adopt horizontal leakage preventing measure, add upper bottom portion percolate exhaust system perfect not, thereby cause that a large amount of percolates are unprocessed just directly have been entered in soil, underground water, environment has been caused to severe contamination.In recent years, country more and more paid attention to garbage loading embeading problem, and many provinces and cities have set up novel refuse landfill.But the quantity in existing garbage disposal plant and scale also can not adapt to the growing requirement of municipal refuse far away, the rubbish of really realizing harmless treatment is only 2.3%.How preventing and treating leachate contamination is the subject matter that first rubbish city landfill yard must be considered.Controlling leachate contamination is generally refuse landfill to be cut to the geographical environment and the geological conditions that carry out the most landfill yards of antiseepage processing ，Er China in dirty dam be difficult to meet antiseepage requirement.
Visible, seepage is the common problem that water conservancy, mine, the Environmental Protection Infrastructures such as soil property dykes and dams, tailing dam, section dirty dam exist, and anti-seepage reinforcing is long-term, the difficult task that these infrastructure face.Seepage control technique conventional in engineering has: concrete anti-seepage wall technology, cement mixing method technology, High Pressure Jet Grouting Technique etc.These anti-seepage reinforcing technology are widely used at home, for the infrastructure such as Chinese large-sized reservoir, Tailings Dam, refuse landfill brought into play important function except danger and anti-seepage reinforcing, but also there are some technical deficiencies.Aspect leakage proof wall material, what existing several impervious wall technology adopted is cement class material, and the antiseepage body of structure is rigidity antiseepage body, larger with elastic modulus of soil body difference, and impervious cracking resistance is not enough; Aspect wall forming machine reason, when existing one-tenth wall class seepage control technique becomes wall, material and the soil body depart from, and grouting class is difficult to form complete continuous body of wall; Aspect form of construction work, existing several impervious wall technology are that the job practices by slotting, stir, spray and vibrating forms antiseepage body in the soil body, to dykes and dams disturbance, destroy larger.The problem such as on the inhomogeneities that cement mixing method technology exist to stir, slurries, emit, stressed unreasonable and pile body is discontinuous, so that pile strength is too low, construction quality poor controllability, anti-seepage effect are undesirable.And High Pressure Jet Grouting Technique makes slurries obtain huge energy by high-pressure installation, easily cause soil body punching failure, at slurries, form in intensity process and very easily cause bulk strength inhomogeneous.As can be seen here, in engineering, these conventional seepage control techniques exist dam body disturbance are destroyed to the shortcomings such as large, the duration is long, cost is higher, construction is inconvenient, particularly for the middle-size and small-size dykes and dams of One's name is legion, existing technological means is not only subject to the restriction of funds, and because equipment is bulky, the difficulty of marching into the arena, this and current China dykes and dams, tailing dam, the growth requirement that cuts dirty dam anti-seepage reinforcing are also far from suitable.Therefore, the research and development of quickening anti-seepage reinforcing new material, new technology, new equipment are current earth embankment, earth dam, tailing dam, cut the infrastructure anti-seepage reinforcing great Scientific And Technical Problems urgently to be resolved hurrily such as water conservancy, mine, environmental protection such as dirty dam.
