Water retaining dam and flood prevention building

Abstract

The invention provides a water retaining dam and a flood prevention building, and relates to the technical field of hydraulic engineering. The water retaining dam comprises a dam body foundation located in the water bottom, a dyke placed on the dam body foundation, a drainage pipe for drainage, a gate for dredging and plugging the drainage pipe, and a driving device for driving the gate to rise and fall; the gate and the drainage pipe are sequentially arranged on the two sides of the dyke in the water flow direction; the drainage pipe is arranged upwards obliquely; the dam body foundation comprises a first round wall, a second round wall, and a middle separation wall arranged at the intersected part of the first round wall and the second round wall; foundation piles are arranged in the first round wall and the second round wall; and capping beams are arranged at the tops of the first round wall, the second round wall and the middle separation wall, and can fixedly connect the top ends of the foundation piles. The problem that a dam body of an existing retaining dam is prone to dam break under major natural disasters like heavy rainfall and an earthquake due to the fact that a foundation of the dam body is not designed reasonably is solved, and the water retaining dam has the characteristics of high structural strength, good durability and reasonable stress.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a water retaining dam and a flood control building. Background technique [0002] Dams have been used to control rivers and divert water since ancient times, and play an extremely important role in water conservancy construction. Nowadays, with the development of human beings, water resources are becoming more and more tense. In order to make full use of water resources, countries are actively building dams in rivers and lakes. Dams are used to intercept the water flow of rivers and channels to raise water levels or regulate flow of water-retaining structures. Among them, the dam can form a reservoir, and can also play the role of regulating runoff and concentrating water head, so the dam is widely used for flood control, water supply, irrigation, hydropower generation and improvement of navigation. [0003] Although the retaining dam has the above-mention...
