Geotechnical board anti-seepage wall self-bursting dam flood diversion gateway

Abstract

The invention discloses a geotechnical board anti-seepage wall self-bursting dam flood diversion gateway, and belongs to the field of the national defense for dealing with the water attack of water conservancy projects and dams of a special spillway project. The geotechnical board anti-seepage wall self-bursting dam flood diversion gateway comprises a geotechnical board anti-seepage wall self-bursting dam (1) and a flood diversion gateway (2) which are designed according to the theory of disaster prevention and reduction of dams in a quantized manner, the geotechnical board anti-seepage wall self-bursting dam (1) includes a full-section geotechnical board anti-seepage wall self-bursting dam, and a geotechnical board anti-seepage wall sub-dam rush-leading self-bursting dam and is suitable for any type of flood diversion way, the flood diversion gateway (2) includes a single-stage geotechnical board anti-seepage wall self-bursting dam flood diversion gateway, and a multi-stage geotechnical board anti-seepage wall self-bursting dam flood diversion gateway, the geotechnical board anti-seepage wall is based on geotechnical board type to select geotechnical board reverse scale folding water stop, geotechnical board closed water stop, geotechnical board single-film cloth reverse scale water stop, geotechnical board double-film cloth reverse scale water stop, geotechnical board I-shaped board single-film lap-joint water stop and closed water stop corresponding types. The geotechnical board anti-seepage wall self-bursting dam flood diversion gateway is suitable for automatic flood diversion of any water type dam, the structure is simple and inexpensive, and the management is convenient.

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 for self-collapsing dikes and flood diversion gates of geotechnical board anti-seepage walls. Background technique [0002] In 2018, my country's hydropower armed police force has been transferred from the military to the civilian population, which marks that my country has leaped from an agrarian society for thousands of years to an industrialized society. In the process of social development and drastic changes, the design concept of water conservancy projects based on military and civilian flood control is no longer suitable for urbanization and mechanization. social conditions. The current design theory that allows hydraulic structures to be designed in accordance with normative standards to be destroyed by floods bey...

Problems solved by technology

3) Flood diversion of small and medium-sized rivers is a problem: On September 10 and 11, 2015, two rivers in Japan successively flooded and burst their dikes, resulting in 7 deaths, many missing and injured, and a large amount of property damage. The river rose for ten years. In the event of a flood, the 4-meter-high embankment of 20 centimeters breaks, which is a difficult problem; flood diversion according to current regulations requires the establishment of flood detention areas. Some small and medium-sized rivers do not have the value of establishing flood detention areas, which has led to some small and medium-sized The embankment of the river cannot be closed and the flood control standard is low; there is no design basis for flood diversion and flood discharge, and it can only be allowed to collapse by itself, resulting in diversion or gully-style soil erosion

6) At present, it is difficult to utilize a large amount of plastic waste such as medical treatment and old chemical fiber clothes

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-collapsing 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 code can only allow a large number of small and medium-sized dams, canal headworks, dikes, and canal buildings Objects and cofferdams were destroyed by floods beyond the standard
