Embodiment Construction

[0027] see Figure 1 to Figure 4 , shows a schematic view of the utility model for the arch end of a high arch dam against downstream air contact explosion protection. The device is mainly composed of an outer box body, a water tank 2 and a dividing plate 3 . Wherein, the outer box body is a knuckle-shaped flat box body composed of a surface panel 1, a side panel and a bottom panel 4, and the sides of the surface panel 1 and the bottom panel 4 are fixedly connected by side panels; The linear multi-layer water tank 2; the partition plate 3 runs through the zigzag multi-layer water tank 2, and is fixedly connected with the zigzag multi-layer water tank 2, the surface panel 1, and the bottom panel 4, and the part inside the zigzag multi-layer water tank 2 should be set A large number of flow holes 9 are convenient for water filling and drainage; side panels 5 are reserved with water filling valves 6 and drain valves 7; water holes 8 are provided in the interlayers of the folded ...

Abstract

The invention relates to a device and method for protecting the arch end of a high arch dam against downstream air contact explosion. The device for protecting the arch end of a high arch dam against downstream air contact explosion, including a flat outer box and a wavy or zigzagging water tank inside, the outer box has a side in the thickness direction and a vertical On the end face, the water tank has a thickness direction parallel to the side surface and a concave-convex surface parallel to the end face. This protective device does not need to modify and destroy the high arch dam itself, it only needs to arrange the device at the corresponding position when the downstream of the high arch dam is under the threat of explosion. It is fast and convenient for deployment.

Description

technical field [0001] The invention relates to the field of anti-explosion protection for arch ends of high arch dams, in particular to a protection device and method for arch ends of high arch dams against downstream air contact explosions, and is suitable for arch ends of high arch dams when wars or terrorist attacks occur Downstream antiknock safety protection. Background technique [0002] As an important basic resource of the country, water conservancy projects are very important both from the perspective of politics and benefits, and the consequences of accidents are serious. Once a war or terrorist attack occurs, water conservancy projects will definitely become the focus of damage. [0003] A high arch dam is an arched water-retaining structure that protrudes upstream. With the help of the arch, it transfers the pressure of the water to the bedrock on both sides of the valley. The characteristic of the arch dam is that its stability mainly depends on the reaction fo...
