Description

Pier foundation structure of water conservancy dam

Technical Field

The utility model relates to a water conservancy dykes and dams technical field, concretely relates to water conservancy dyke dam mound base structure.

Background

Dykes are the generic term for "dikes" and "dams", also broadly referring to water-resistant and water-retaining buildings and structures, and modern dams are mainly of two types: 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 main characteristic of concrete dams is that the self weight is used for supporting the pressure of a water body, but the cost of concrete is high.

On the other hand, firmly snatch the ability through dyke mound base main part and ground and be favorable to improving the water pressure resistance ability of dykes and dams, but current mound base main part is generally that direct pouring mound base main part or only carry out fore-and-aft pinning with simple anchor pile, and the effect is limited.
