Description

Prevention of seepage hydraulic engineering dykes and dams

Technical Field

The application relates to the technical field of dams, in particular to an anti-seepage hydraulic engineering dam.

Background

Dam: the general term dikes and dams also broadly refers to water-tight and water-retaining buildings and structures. Dams mainly have two categories: earth-rock dams and concrete dams. 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.

With respect to the related art in the above, the inventors consider that the dikes are easily nested by termites, thereby causing the dikes to crack, affecting their water seepage preventing ability.
