Background
At present, hydraulic engineering is an engineering constructed for controlling and allocating surface water and underground water in the nature to achieve the purposes of removing harm and benefiting. Also known as water engineering. Water is a valuable resource essential for human production and life, but its naturally occurring state does not completely meet the needs of human beings. Only when hydraulic engineering is built, water flow can be controlled, flood disasters are prevented, and water quantity is adjusted and distributed to meet the requirements of people on water resources in life and production. Hydraulic engineering needs to build various types of hydraulic buildings such as dams, dikes, spillways, water gates, water inlets, channels, transition troughs, rafts, fishways and the like so as to achieve the aims.
The hydraulic engineering not only affects the economy and the society of the area through the construction task, but also affects the natural appearance, the ecological environment and the natural landscape of rivers, lakes and nearby areas, and even affects the regional climate to different degrees. The influence has advantages and disadvantages, and the influence must be fully estimated during planning and designing, so that the positive effect of the hydraulic engineering is exerted in an effort, and the negative influence is eliminated.
A dam is a water retaining structure which intercepts water flow of river channels to raise the water level or adjust the flow. Can form a reservoir, raise the water level, regulate runoff and concentrate water head, and is used for flood control, water supply, irrigation, hydroelectric power generation, shipping improvement and the like.
The traditional dam is mostly an earth-rock dam or a concrete dam, and the dam body is deformed and more seriously crashes due to overhigh pressure and large seepage because the dam body is subjected to scouring, erosion or concrete aging and the like of running water for a long time. And after long-term use, the left dam body and the right dam body can shift due to water flow scouring and geological changes.
The existing partial dam has the advantages of simple structure and poor seepage-proofing and corrosion-resisting properties, and a sluice in a flood discharge channel of the dam is of an integral structure, so that the water volume can be suddenly increased or reduced during switching on and off of the sluice, the dam body is easily impacted, and the safety of the dam is reduced.
