Description

High polymer promotes grouting method
Technical field
The invention belongs to infrastructure anti-seepage reinforcing technical fields such as water conservancy, mine, environmental protection, the high polymer that be specifically related to earth embankment, earth dam, tailing dam, uses when cutting anti-seepage reinforcing such as dirty dam promotes grouting method.
Background technology
Since the founding of New, infrastructure constructions such as the water conservancy of China, mine, environmental protection have obtained remarkable achievement, and important function has been brought into play in China's economic growth and social progress.Aspect the water resource infrastructure construction and since the most water conservancy projectss of China build in last century 50 to the seventies, be limited to economic technology condition at that time, many reservoirs designs and construction quality " inadequate natural endowment ".Through long-time running, long neglected and in disrepair, aging serious, sick dangerous problem is very outstanding.At present, built in China becomes all kinds of reservoirs to reach 8.7 ten thousand, occupies first place in the world.But about 40% small reservoir, 25% big-and-middle-sized reservoir belong to dangerously weak reseroirs, people's lives and properties and social stability are constituted greatly threaten.China's dyke is built with a long history, but majority is to form through heightening and thickening gradually over the years, and levee body fills soil and is mostly that different times fetches earth on the spot, fills quality nearly less than designing requirement, has different security hidden danger.In existing more than 40,000 dangerously weak reseroirs of China, be earth and rockfill dam more than 90%, and most dyke is the soil property dyke.According to initial estimate, about small-sized dangerously weak reseroirs more than 50% need 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 prone to send out the position, also is the dangerous matter sources of latent huge potential safety hazard.In addition, also contain various poisonous and harmful substances in the mine tailing storehouse, 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 many mine tailings storehouse, China mine, be in the less than 70% of normal operation at present, the industry that has is in danger, sick, the service state of exceeding the time limit above 40% mine tailing storehouse, and mine tailing storehouse major accident happens occasionally.And how seepage is effectively administered seepage and is guaranteed that the safe operation of mine tailing storehouse seems very urgent and important as the one of the main reasons of tailing dam accident.Aspect the 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 the horizontal leakage preventing measure, it is perfect inadequately to add upper bottom portion percolate row guiding systems, thereby causes that a large amount of percolates are unprocessed just directly have been got in soil, the underground water, and environment has been caused severe contamination.In recent years, country more and more paid attention to the 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, realize that really the rubbish of harmless treatment is merely 2.3%.How preventing and treating the percolate pollution is the subject matter that rubbish city landfill yard must at first be considered.It generally is refuse landfill to be cut dirty dam carry out the antiseepage processing that the control percolate pollutes, and the geographical environment and the geological conditions of the most landfill yards of China are difficult to satisfy the antiseepage requirement.
It is thus clear that seepage is the common problem that water conservancy, mine, environmental protection infrastructure such as soil property dykes and dams, tailing dam, section dirty dam exist, anti-seepage reinforcing is long-term, the difficult task that these infrastructure face.Seepage control technique commonly used in the engineering has: concrete anti-seepage wall technology, cement mixing method technology, High Pressure Jet Grouting Technique etc.These anti-seepage reinforcing technology have obtained widely using at home, for infrastructure such as Chinese large-sized reservoir, mine tailing storehouse, refuse landfill remove the danger and anti-seepage reinforcing has been brought into play important function, but also have some technical deficiencies.Aspect the leakage proof wall material, what several kinds of existing impervious wall technology adopted is cement class material, and the antiseepage body of structure is rigidity antiseepage body, and is bigger with the elastic modulus of soil body difference, and impervious cracking resistance is not enough; Aspect the wall forming machine reason, the material and the soil body broke away from when existing one-tenth wall class seepage control technique became wall, and the grouting class is difficult to form complete continuous body of wall; Aspect form of construction work, several kinds of existing impervious wall technology are in the soil body, to form the antiseepage body through the job practices of slotting, stir, spraying and vibrating, and destroy bigger to the dykes and dams disturbance.There is on the inhomogeneities that stirs, the slurries problem such as emit, stressed unreasonable and pile body is discontinuous in cement mixing method technology, so that pile strength is low excessively, and construction quality poor controllability, anti-seepage effect are undesirable.And High Pressure Jet Grouting Technique makes slurries obtain huge energy through high-pressure installation, is prone to cause soil body punching failure, forms in the intensity process at slurries very easily to cause bulk strength inhomogeneous.This shows; These seepage control techniques commonly used exist the dam body disturbance are destroyed big, shortcomings such as the duration is long, cost is higher, construction inconvenience in the engineering; Particularly for the middle-size and small-size dykes and dams of One's name is legion, existing technological means not only receives 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 also are far from suitable.Therefore, the research and development of quickening anti-seepage reinforcing new material, new technology, new equipment are the great scientific and technological problems that infrastructure anti-seepage reinforcings such as water conservancy, mine, environmental protection such as current earth embankment, earth dam, tailing dam, section dirty dam need to be resolved hurrily.
