Function of flood dike

A flood dike is a flood dike, which refers to a dam built to prevent the river from flooding. The general term for dams also refers to waterproof and water-retaining buildings and structures. For example, it is necessary to strengthen dike construction to prevent floods. There are two main types of modern dams: earth-rock dams and concrete dams. In recent years, large dams have adopted high-tech reinforced concrete buildings.

Types of flood control dams:

Water retaining structures built along the edges of rivers, canals, lakes, coasts or flood discharge areas, flood diversion areas and reclamation areas are called dikes. Dike is the earliest important flood control project widely used in the world. Dike construction is the main measure to prevent flooding and protect residents and industrial and agricultural production. After the dike restrains the flood, the flood will be confined in the spillway, which will increase the water depth and flood discharge speed of the same flow, which is beneficial to flood discharge and sediment discharge. In addition, the embankment can resist wind, waves and tides.

Dike construction is generally closely combined with river regulation. For example, in order to expand the flood discharge capacity of rivers, in addition to heightening and thickening dikes, measures should also be taken to dredge rivers, cut and straighten them, rebuild and retreat, and remove water-blocking obstacles in rivers in time. In order to reinforce dikes, it is necessary to build river water potential control and guidance projects and dangerous section protection projects.

Dikes can be divided into river banks, river banks, lake dikes, seawalls, reservoirs and dikes in low-lying areas in flood storage and detention areas. Dikes can be divided into trunk dikes, branch dikes, sub-dikes, remote dikes, separation dikes, flood control dikes, dikes (embankments) and breakwaters. Dike can be divided into earth dike, stone dike, earth-rock mixed dike and concrete flood control wall according to building materials.
