A mountainous area flood control water storage transportation distribution system

Abstract

A flood control and water storage, transportation and distribution system in mountainous areas, characterized in that: it includes a main waterway, in which there are first rocks with different heights, and the height of some of the first rocks is greater than the highest water level when a flood erupts. A rock together with the main waterway guides the water flow to make twists and turns and blocks and impacts the water flow. There are multiple Ω-shaped energy-dissipating sedimentation tanks on one or both sides of the main waterway, and each Ω-shaped energy-dissipating sedimentation tank The water inlet is connected to the main waterway, and the water inlet of the Ω-shaped energy-dissipating sedimentation tank is deeper than the main waterway and has a smaller diameter, so that when there is less water, it mainly flows into the Ω-shaped energy-dissipating sedimentation tank. The construction requirements and cost of the flood control and water storage transportation and distribution system in this mountainous area are low, and there is less siltation. When the flood breaks out, the protective facilities are not easy to be washed away and the water quality is good. In the dry season, sufficient water can be obtained through distributed water storage. source of water.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a flood control, storage, transportation and distribution system for mountainous areas. Background technique [0002] In existing mountainous areas, retaining dams are generally used to prevent floods during the rainy season. The energy dissipation principle of the retaining dams is to use the height difference of the dams to form a downward discharge like a waterfall. However, the construction requirements and costs of retaining dams are relatively high, and it is easy to deposit branches and sediment, and it is easy to be washed away due to the frontal impact of water flow when a flood occurs. Moreover, when floods occur, they carry a large amount of sediment, and the water quality is generally poor. In addition, some mountainous areas have a dry period of 1-2 months every year, which will have a great impact on production activities such as fish farming i...

Problems solved by technology

However, the construction requirements and costs of retaining dams are relatively high, and it is easy to silt up branches and sediment, and it is easy to be washed away due to the frontal impact of water flow when a flood occurs.

Moreover, when floods occur, they carry a large amount of sediment, and the water quality is generally poor. In addition, some mountainous areas have a dry period of 1-2 months every year, which will have a great impact on production activities such as fish farming in mountainous areas or the ecology of mountainous areas.
