Problems solved by technology

Theoretically, the limited quantified flood standard cannot solve the problem of engineering water damage caused by infinite super-standard floods; embankments with earth-rock structures cannot resist super-standard floods
At present, there is also a lack of disaster prevention and mitigation design theory for auxiliary dam flood diversion of reservoirs and controllable flood diversion of special spillways

specific Embodiment approach

[0030] The specific embodiment: below in conjunction with accompanying drawing, the best embodiment of the present invention is described in detail:

Embodiment

[0031] Embodiment: a kind of disaster prevention and mitigation method (seeing figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 ), constructing the theory of disaster prevention and mitigation of super-standard flood dams, and solving the problem that the specific flood standards stipulated in the norms cannot solve the problem of infinite super-standard flood engineering water damage. It includes: 1) On the basis of existing design theories and norms, based on The mechanism of flood damage in the flood discharge beach, increase the design of disaster prevention and mitigation of water damage in excess of the standard flood project, and adopt controllable extraordinary flood diversion measures of geosynthetic materials that do not permanently occupy land resources, do not damage the environment, and are low in cost, to prevent the collapse of the dam caused by surge waves In the event of irresistible floods, people and animals have the opportunity to esc...

Abstract

The invention discloses a disaster prevention and reduction method for preventing overproof flood dyke water damage, and belongs to the technical field of very flood diversion for flood, drought, disaster reduction and water conservancy projects. By the aid of the flood diversion system for overproof flood dyke disaster prevention and reduction, great calamity caused by disastrous dam-failure surge can be prevented, people and livestock can have the chance to escape when encountering irresistible flood, the aims of turning great deluge into waterlogging and turning small deluge into benefits are realized, soil cannot be occupied permanently, implementation is convenient and manufacturing cost is low. The method involves in overproof flood dyke protection with diverted flood dispersed towards the farmland and controllable flood diversion overproof flood dyke disaster prevention and reduction theory, novel geosynthetics controllable very flood diversion measures, an overproof flood novel river dyke protection flood diversion system and flood-fighting and emergency rescue flood diversion system, an overproof flood novel reservoir very flood diversion system, and an overproof flood novel headwork very flood diversion system. The method is suitable for disaster prevention and reduction design of river dyke, reservoir, headwork and channel crossing very flood diversion, and is also suitable for overproof flood dyke flood-fighting and emergency rescues.

Description

technical field [0001] The invention belongs to the fields of flood and drought and disaster reduction technology and extraordinary flood diversion of water conservancy projects, and specifically relates to a method for preventing and reducing disasters that prevent superstandard floods from destroying dams. Background technique [0002] On September 10, 2015, a 4-meter-high embankment in Japan burst. Entire houses and rows of vehicles were washed away, causing many casualties and missing, and a large amount of property loss. Excessive floods and dam damage are a worldwide problem. After the Great Flood in my country in 1998, when the flood control standards of river embankments were generally raised, the flood water flowed into the river, increasing the probability of floods downstream, increasing the height of the embankment, and increasing the water storage in the river. Flood fighting and rescue teams are also in danger. The vicious case of dike breaks in Japan may be rep...
