Flood-control and water-storage transportation and distribution system in mountain areas

Abstract

The invention discloses a flood-control and water-storage transportation and distribution system in mountain areas. The flood-control and water-storage transportation and distribution system is characterized in that the flood-control and water-storage transportation and distribution system comprises a main water channel, first rocks which are staggered high and low are arranged in the main water channel, the height of part of the first rocks is larger than the highest water level when a flood breaks out, the first rocks and the main water channel jointly guide water flow to twist and turn, andblock and impact the water flow, a plurality of omega-shaped energy-dissipation sedimentation tanks are arranged on one side or two sides of the main water channel, water inlets of all the omega-shaped energy-dissipation sedimentation tanks communicate with the main water channel, and moreover, the water inlets of the omega-shaped energy-dissipation sedimentation tanks are deeper than the main water channel and have smaller diameters, so that when less water exists, the water mainly flows into the omega-shaped energy-dissipation sedimentation tanks. According to the flood-control and water-storage transportation and distribution system in the mountain areas, the construction requirements and the cost are low, the deposition is less, when the flood breaks out, protective facilities are notprone to being destroyed, the water quality is good, and enough water sources can be obtained through distributed water storage in dry seasons.

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.
