Description
Technical field
The invention belongs to dykes and dams flood diversion hydraulic engineering technical field, be specifically related to dykes and dams super standard flood flood diversion siphon pipe racks.
Background technology
There is the super standard flood that manpower cannot be resisted in Heilungkiang in 2013, under existing water conservancy specification with technical conditions, realize " guaranteeing the safety of flood-fighting army " the biggest with the flood control case in advance difficulty of this target of embankment safety, if realizing this target by innovation theory, innovative approach, the most just solving dykes and dams super standard flood to overflow top and burst the global difficult problems of hurting people or smashing objects, following case and the difficult problem explanation present invention will produce huge economic results in society；Following case and the difficult problem explanation present invention are to ensureing that national economy has urgency.
Super standard flood dyke overflows top and bursts case: within 2015, Japanese JIUYUE inrushes on the 10th, and whole house, vehicle in a row are flushed away, and causes that many people injures and deaths are missing, fortune loss.Chinese super standard flood in 2014 causes damaging at dykes and dams 2.4 ten thousand.Heilungkiang dykes and dams in 2013 occur the loss of bursting of unrestrained dike serious, if the troop that will make to speedily carry out rescue work of blocking up by force owing to having inconvenient traffic falls into dangerous situation even impasse.Sha Lan river, Ningan City, Heilongjiang Province's in June, 2005 super standard flood overflow dike burst, cause the heavy casualties of dead 117 people.1998 dead 3004 people in the annual flood whole nation, direct economic loss reaches 166,600,000,000 yuan, and wherein Jiujiang embankment breaches a dyke, and heavy 9 ships and a large amount of relief materials of input, tens thousand of the army and the people 4 talentes control.
Dam overflows top and bursts case: within 2014, Chinese super standard flood causes 4 small reservoirs to break down, India Ma Qiu in 1979 overflows top 3000 people that break down and suffers from drowned, the reservoirs such as Henan slab bridge, stone overbanks in 1975 overflow top and break down, downstream close at hand speedily carry out rescue work troop none escape by luck, 2.6 ten thousand people suffer from drowned, and economic loss reaches 10,000,000,000 dollars.Many of Hebei province reservoir overflow top and broke down in August, 1963, and 1467 people suffer from drowned, the unrestrained top dam break 59 of nineteen fifty-one to 1986 year other National Flood of the world.
The difficult problem that super standard flood dykes and dams face: in the case of river dyke is the most up to standard, flood all converges in river course, increases downstream and the probability of flood occurs, and dykes and dams increase, and river course water-holding quantity increases, and once breaches a dyke, it is simply that extinction.Run into super standard flood guarantor's dykes and dams not burst, employing means only have three, " store, keep off, point ", " reservoir stores, dykes and dams keep off " is the most limited, once running into irresistible flood, three kinds of means reach capacity and flood diversion building can not now be built, and burst inevitable, this is the difficult problem that existing hydraulic engineering technology faces, and in these three option, only dykes and dams are protected in flood diversion is completely safe plan.Owing to small reservoir drainage area is little, amount big, the probability that rare storm centre concentrates in the drainage area of small reservoir is big, and small reservoir importance microassociation economic benefit is low, flood control standard is low, occur unrestrained dam breaking inevitable, in 14 years, state-owned 4 small reservoirs occur unrestrained dam breaking to be exactly illustration, and this is the difficult problem that small reservoir runs into that super standard flood faces.Flood diversion on sub-bottom changes (flood discharge) building form has flood-diversion sluice and the spillway of hafnium structure at present, cross water and soil dam, buried penstock under dam, shaft spillway, siphon spillways and flood diversion of artificially breaching a dyke, these flood diversion excessive flood building all now can not be built when occurring super standard flood to speedily carry out rescue work, shaft spillway, siphon spillways surpass the low emergency spillway being not suitable as earth and rockfill dam hinge of the ability of letting out, siphon spillways must reach certain water level condition just automatically starting, if the siphon spillways of reservoir need actively flood diversion, must possess upstream and downstream gate valve and water filling pipe valve and dissipation and scouring facility, these facility costs are high.Now from weir formula floodway of bursting, be equivalent to without lock hafnium structure spillway, its cost is the highest, and once start and face little water and produce uncontrollable big burst, now flood diversion building energy dissipation type surface current, bucket, choose stream, surface current, bucket need certain hydraulics, and underflow, surface current, Dissipation Energy in Solid Bucket must have hafnium structure protection-apron, and flip trajectory bucket must be chosen bank and form safety punching hole with head.Reservoir without energy-dissipating installation breaks the emergency spillway of auxiliary dam, once starts cost high and uncontrollable, and other emergency spillway not only cost height also needs to certain landform, geological conditions.
Super standard flood dike overflows the reason burst of top: the common feature of these damaged or destroyed by flood cases is exactly the major natural disasters running into super standard flood, economically developed country exists too, this is a global difficult problem, the dam designs theory that countries in the world are general, it is to be designed engineering according to the concrete standard of flood that quantifies of specification regulation, guarantee not occur engineering damaged or destroyed by flood in specification, the social and economic condition difference of various countries is only that its codes and standards are different, developed country's standard height generation super standard flood engineering damaged or destroyed by flood probability is low, and developing country's standard low generation super standard flood engineering damaged or destroyed by flood probability is high.The problem that can not solve unlimited super standard flood engineering damaged or destroyed by flood by the finite quantization standard of flood of specification in theory；The dykes and dams of rock structure cannot resist super standard flood.Currently also lack the auxiliary dam flood diversion of reservoir, the design theory of preventing and reducing natural disasters of the controlled flood diversion in emergency spillway.
Utilize the flood discharge beach damaged or destroyed by flood mechanism that leaf is emerging, build to farmland, the novel flood diversion of beach dispersion flood diversion is theoretical and measure, provides a kind of new construction for solving an above series of difficult problem.
