Reservoir dam

Abstract

The invention discloses a reservoir dam, which comprises a main dam and a plurality of sub dams, wherein the main dam is transversely arranged in a reservoir, all of the sub dams are sequentially and uniformly ranged at the upper stream of the main dam, and the tops of the sub dams are lower than the lowest liquid level of the water flow at the upper steam of the main dam. The reservoir dam has the advantages that the water flow is segmented through the sub dams, and the water flow pressure is shared, so the main dam and each sub dam respectively bear smaller pressure, the damage to the main dam and the sub dams is smaller, the trimming frequency of the main dam and the sub dams is reduced, in addition, the dam collapse cannot easily occur, and the safety guarantee is added to residents and lands at the down stream; in addition, even when the main dam collapses, the sub dams at the upper stream can prevent most river water at the upper stream from downwards flowing, only a small part of river water downwards flows, and the impact on the down stream river bed is smaller, so the lower stream flood possibility is reduced; in addition, the tops of the sub dams are lower than the lowest liquid level of the water flow at the upper stream of the main dam, the navigation on the water level is also not influenced, and the actual application advantage is obvious.

Description

technical field [0001] The invention relates to the field of hydraulic engineering, in particular to a reservoir dam. Background technique [0002] Reservoir dams are water-retaining structures used to intercept river water flow to raise water levels or regulate flow. Reservoir dams are built on river channels, and water flow can be intercepted to form reservoirs. During the rainy season, the sluice gates on the dam can properly discharge water, which can achieve the functions of flood control and power generation. When the dry season comes, the concentrated water stored in the reservoir can be used for plant irrigation and water supply for residents; therefore, building a reservoir dam on a river can play a role to regulate water resources. [0003] Existing reservoir dams generally intercept the water flow by a single dam to form a reservoir, and the dam bears all the pressure of the water flow, that is, the dam needs to bear the pressure of the water stored in the reserv...
