Problems solved by technology

The dam break wave formed by this kind of dam failure may not only cause bank collapse and other losses in the reservoir area, but more seriously, it will lead to disastrous consequences in the downstream areas of the reservoir.

Embodiment Construction

[0031] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0032] A method for preventing earth dam overflow and collapse, based on a remote control device for preventing earth dam overflow and collapse, such as figure 1 and figure 2 As shown in the figure, the remote control device for preventing earth dam overflow and collapse consists of geomembrane, electronic water level gauge, and remote control hydraulic support.

[0033] Its overall structure consists of a geomembrane used to prevent the dam crest and the downstream surface from being scoured, a remote-controlled hydraulic support used to support the geomembrane at ordinary times, and an electronic water level gauge used to detect the water level.

[0034] In the present invention, a remote control device can be used to loosen the hydraulic support before the flooding of the small and medium-sized earth dams, and the geomembrane rolls will be ...

Abstract

The invention discloses a method for preventing earth dam overtopping breaking. The method includes the following steps that an electronic water level gauge detects a water level of a water body in real time, when the electronic water level gauge detects that the water level reaches a dangerous water level, an alarm sends an alarm signal to an operator on duty of an earth and rockfill dam, and theoperator on duty judges whether a waterproof membrane is laid down or not according to the alarm signal and a surveillance video or on-site observation. A support frame controlled remotely is in a supporting state at ordinary times, a support rod of the support frame controlled remotely is attached to the top of a dam so as to support a waterproof membrane roll, the support frame controlled remotely is laid down through remote closing in a distress situation, the waterproof membrane without supporting is automatically unfolded to overspread the downstream face with the gravity action and thewater scouring action, and the action of preventing dam breaking due to scouring damage is achieved.

Description

technical field [0001] The invention relates to a method for preventing earth dams from overflowing and breaking. Background technique [0002] Reservoirs are important infrastructures of every country, and for our country, reservoirs are an important part of every comprehensive flood control engineering system. Although it has been many years since the first dam was built in our country, and dam engineering technology is constantly improving, incidents of reservoir failures still occur every year. Most of the dam-broken reservoirs are earth dams, accounting for 94.5% of the dam failures, and if the earth-rock mixed dams with similar structural properties are added, the proportion is as high as 95.8%. Reservoirs composed of earth-rock dams are mostly located in remote hilly areas, commanding heights, and when they burst, the reservoir water suddenly leaks, causing the downstream water level to rise sharply and the reservoir water level to drop sharply. The dam break wave f...
