Description
Technical Field
The invention relates to the technical field of dams, in particular to an anti-scouring reinforced water conservancy dam.
Background
Dikes refer to water-resistant and water-retaining structures and structures used to prevent water damage. Modern dams come in two main categories: earth and rockfill dams and concrete dams. In recent years, large dams are constructed with high-tech reinforced cement. An earth-rock dam is a wide dam constructed with earth or stone. The bottom part is wider than the top part because the bottom part is subjected to a much greater water pressure than the top part. Earth and rockfill dams are mostly built across large rivers and are made of common and cheap materials. Because the material is looser, the dynamic shaking of the foundation can be borne. But water will slowly penetrate into the dike, reducing the firmness of the dike. Thus, engineers may add a layer of waterproof clay to the dam surface or design channels to allow some water to flow away. Concrete dams are constructed of concrete, usually in deep and narrow valleys, because only concrete can withstand the high water pressure at the bottom of the dam. Concrete dams can be subdivided into concrete gravity dams, concrete arch dams, concrete buttress dams and the like. The concrete dam is mainly characterized in that the self weight is utilized to support the pressure of a water body.
The conventional embankment has the following problems in using and preventing flood: the conventional dam is generally a concrete dam, and a dam wall formed by the concrete dam is used for blocking the impact of flood. However, the inclined plane type or vertical plane type dam wall enables the whole dam body to directly impact with flood, the front pressure generated by water potential cannot be decomposed, the whole protection of the dam wall is not facilitated, the dam wall can instantly bear large impulsive force, and the dam body is easy to be in a dangerous situation. In addition, after the water level of the traditional dam body reaches a certain critical height, no automatic pressure reduction facility exists, and the danger of bank breaking instantly occurs when the dam body bears larger water pressure.
