Problems solved by technology

At present, there is no design theory for self-collapsing dikes. The artificial blasting flood diversion method is generally used. The advantage can overcome the uncertainty of consolidated clay and hardened road surface. The disadvantage is that the flood season management and explosives management require high requirements. Once the blasting flood diversion is out of control
The failure of dams is very common. There is no feasible and consensus design theory for self-failure dams, and there is no complete set of technologies. The reason is that the current design theory of self-failure dams is to quantify and meet the flood standards stipulated in the code, that is, from the start of dam failure to the reservoir. The time when the water level rises to the standard water level coincides with the time of self-breakage of the dam, and the mechanism of various dam self-breakage phenomena is very complicated. At present, there is no mathematical model to solve it; at present, there is only a large-scale overall test of the self-breakage dam of the diversion channel through test methods. There are similarities. The statically indeterminate structure of the three-sided consolidated clay of the flushing trough complicates the problem. At the same time, the test cannot solve the problem of uncertainty, infinity of flood and uncertainty of self-collapse caused by consolidated clay and hardened road surface. At present, all self-breaking dams that have been designed through experiments must be rare and rare floods, which are hardly verified by practice; limited by economic and technical conditions, the regulations can only allow a large number of small and medium-sized dams, canal headworks, and embankments with low-standard floods , canal system buildings and cofferdams were destroyed by excessive floods

Embodiment 1

[0034] Example 1: Design example of a flood diversion system in a river basin. According to the theory of disaster prevention and mitigation of super-standard floods, self-collapsing and fast self-collapsing dams are used for reservoirs, canal head projects, important embankments and intersecting buildings with traffic requirements; For check dams, pond dams, and valley squares with traffic requirements, self-collapsing dams with faster self-collapsing are adopted; for embankments without traffic requirements, the same self-collapsing clay inclined wall embankments and clay core wall self-collapsing embankments can be used; for embankments without traffic Clay homogeneous dykes on clay foundations that require short-duration surges should use partitioned clay anti-seepage body self-collapsing dams and clay homogeneous self-collapsing dykes. Short-duration floods will not collapse, long-duration floods will self-collapse, and non-hardened pavement is allowed. Overflow of overflo...

Embodiment 2

[0052]Embodiment 2, extreme flood diversion of war floods and extraordinary flood diversion of cross-border rivers between countries: 1) Response to war floods by decentralized flood diversion and decentralized water storage. In response to the water attack and dam break surge disaster of the upstream reservoir, the auxiliary dam and the low dam on the bank are built to prevent or reduce the dam break disaster, and the dikes or barrages on both sides of the canal head project are built to prevent the dam break surge from destroying the canal. The first project; in the upstream of the flood diversion gate of the river, it is currently built to prevent the dam break surge from destroying the flood diversion gate and diverting; the dikes on both sides of the river are scattered and built more to prevent the dam break surge from destroying the embankment, causing river diversion and dike break surge disasters. In response to water attack cutting off the water source of the reservoi...

Embodiment 3

[0053] Example 3, Flood Control Management of Flood Diversion Protection Dams. A small cross-border river does not have the conditions to build flood detention areas. Building flood diversion gates is not only expensive, but also difficult to manage far away from villages. It is difficult to select flood gates without building flood detention areas. , Concentrate on flooding one unfair objection. In view of this situation, the present invention is used to distribute floods in a balanced manner to the beach fields, the low-standard flood floods are diverted using a 10-period rotation system, and an automatic forecasting system is installed at the flood diversions. Due to the low cost of the present invention, unmanned management, automatic controllable flood diversion is economically and technically feasible; because of its fair flood diversion, the public can accept the solution to the problem of site selection and management of flood protection dams in non-flood detention area...

Abstract

The invention discloses a design method of a self-collapsing dike flood diversion channel, and belongs to the field of national defense of water conservancy projects of non-normal spillway projects and flood diversion gates and water attack response of dikes. The method comprises a self-bursting dam (1-), a flood diversion channel (2), a self-collapsing dike disaster prevention and reduction design theory and an over-standard flood dike disaster prevention and reduction theory. The self-bursting dam (1-) comprises a self-bursting geotechnical plate impervious wall self-bursting dam, a self-bursting geotechnical membrane cloth impervious curtain self-bursting dam, a self-bursting geotechnical plate membrane cloth impervious curtain body sub-dam guiding and flushing self-bursting dam, a flooding undermining guiding and flushing self-bursting dam, a partition clay impervious body self-bursting dam and a high-weir overflow slow self-bursting dam, a self-bursting geotechnical plate membranecloth anti-seepage curtain body guiding and flushing opening self-bursting dam and a flooding and confluence guiding and flushing self-bursting dam. The flood diversion channel (2) comprises a reinforced concrete flood diversion channel, a reinforced concrete flood diversion gateway and a geosynthetic material flood diversion channel. The invention is simple in structure, low in cost, convenientto manage and suitable for automatic flood diversion of any water head dam.

Description

technical field [0001] The invention belongs to the technical field of dike and dam extreme flood diversion conservancy engineering, and also belongs to the technical field of national defense against water attack, and specifically relates to a design method of a self-collapsing dike and a flood channel. Background technique [0002] Embankment breaches without flood diversion facilities and people have no time to escape: the authorities often warn of typhoons and rainstorms, but due to the uncertainty of exceeding the standard flood and the location of embankment breaches, it is rare for local people to encounter embankment breaches Yes, this has led to the public not paying attention to the flood warnings issued by the authorities, which is a problem faced by flood control management; it is also a problem to divert the flood of small and medium-sized rivers in the lack of construction of flood diversion areas; The dam was breached by war water attack, which resulted in the...
