Intelligent control siphon drainage and flexible stilling pool system for silt dam

Abstract

The invention relates to the technical field of silt dam and tailing dam engineering drainage, and discloses an intelligent control siphon drainage and flexible stilling pool system for a silt dam. The system comprises a floating type water taking tank, a drainage pipe, a connecting flange, an upward protruding type water injection and gas collection device, a downstream side drainage pipe, a dam body, a flexible corrugated pipe, a flexible stilling pool system and a drainage pipe floater, wherein the water drainage pipe is in communication with the floating type water taking tank through the connecting flange and floats on the water surface of a reservoir area through the water drainage pipe floater, the dam body is provided with an upstream water drainage pipe groove, a downstream water drainage pipe groove and a dam crest water passing duct, the upward protruding type water injection and gas collection device is installed on the dam body, and the drainage pipe and the downstream side drainage pipe are laid in the upstream drainage pipe groove and the dam crest water passing duct correspondingly. The intelligent control siphon drainage and flexible stilling pool system is suitable for the technical field of silt dam and tailing dam engineering, the engineering problem of an existing drainage system is effectively solved, and the drainage requirement of the silt dam can be well met.

Description

technical field [0001] The invention relates to the drainage field of check dams and tailings dam projects, in particular to an intelligent control siphon drainage and flexible stilling pool system for check dams. Background technique [0002] Warping dams are important engineering measures for soil and water conservation, silted land reclamation, traffic improvement and ecological protection in the Loess Plateau area. The gullies and gullies in the Loess Plateau of my country are widely distributed. Strong cutting results in serious soil erosion, sparse vegetation, frequent landslides and mudslides, extremely fragile ecological environment, and poor people's lives. [0003] Warping dam is a water and soil conservation project created by the ancestors in Northwest China to control gullies, and its history can be traced back to the Ming Dynasty. By "building dams and building fields", the ancestors earned a ration that guaranteed the harvest during drought and flood. At the...

Problems solved by technology

With the traditional drainage system, pipeline silting often occurs, resulting in the loss of drainage function, resulting in dangerous situations in the dam body due to the inability to drain water, and even dam failure

At the same time, the arrangement of culvert pipes through the dam is adopted. If the pipes are made of concrete, the pipes are prone to rupture and cause safety hazards. The pipes made of cast iron will be corroded and damaged, which seriously affects the safety of the dam body. Drainage wells are arranged in the upstream reservoir area, which cannot be effectively prevented. Sediment deposits. At the same time, as the upstream reservoir area deposits, drainage wells also need to follow up, making management and maintenance difficult during the operation period.

[0006] Due to the insufficient drainage system of check dams, the risk of water damage accidents and dam failures of check dams is far more serious than that of conventional earth-rock dams, which has become a bottleneck problem restricting the development of check dams.

[0007] Due to the large number of check dams, the complex situation, and the lack of professional management, problems cannot be discovered in time. After the danger is discovered, personnel and mechanical equipment are required to go to the scene for emergency rescue, and the danger is further deteriorated due to information lag.

The biggest danger of a check dam is that the reservoir area is not well drained during the flood season, which leads to a rapid rise in the water level of the reservoir and endangers the safety of the dam body.
