Description

technical field

[0001] The invention relates to the technical field of spur dikes, in particular to a self-elevating spur dike whose height is automatically adjusted according to the water level. Background technique

[0002] Spur dikes are widely used hydraulic structures in river course or waterway regulation projects. Its main function is to protect the river bank slope from being directly eroded by the incoming flow and cause scour damage. At the same time, it also improves the waterway, maintains the river and It plays an important role in the protection of aquatic ecological diversity. Spur dikes can block and weaken the eroding effect of oblique waves and coastal currents on the coast, promote the siltation of dam fields, form new beaches, and achieve the purpose of protecting the coast. In traffic construction, river beach reclamation and tidal flat projects, spur dams are also one of the commonly used buildings. Long spurs can deflect the axis of water flow and te...
