What auxiliary energy dissipators are there in the sluice?

The auxiliary energy dissipator of sluice has stilling piers and teeth. These auxiliary energy dissipators can help reduce the energy generated by water flow, reduce the impact of water flow on the sluice and protect the normal operation of the sluice.

Build low-head hydraulic structures on rivers and canals, and use gates to control flow and adjust water level. Closing the sluice can hold back flood and tide or raise the upstream water level, and meet the needs of irrigation, power generation, shipping, aquatic products, environmental protection, industry and domestic water.

Opening floodgates can release floods, waterlogging, abandoned water or waste water, and can also supply water to downstream rivers or channels. In water conservancy projects, sluices are widely used as structures for retaining water, draining water or taking water. Closing the sluice can block flood, tide and water, raise the upstream water level and meet the needs of upstream water intake or navigation.

Flood discharge, drainage, sand washing, water intake by opening floodgates, or adjusting the flow according to the downstream water demand. Sluices are widely used in water conservancy projects, mostly built in rivers, canals, reservoirs, lakes and coastal areas.

China has a long history of building sluices. From 598 BC to 59 BC1year, when Chu Lingyin and Sun Shuai built Shaopi Irrigation District in Shouxian County, Anhui Province, they set up five gates to divert water. With the improvement of sluice construction technology and the emergence of new varieties of building materials, sluice construction is increasing day by day. After 1949, the construction of large-scale modern sluice has generally risen in China and accumulated rich experience.

form

The sluice consists of a sluice chamber, an upstream connecting section and a downstream connecting section. The lock chamber is the main body of the sluice, which is equipped with bottom plate, gate, hoist, pier, breast wall, working bridge, traffic bridge and so on. The gate is used to retain water and control the flow through the gate, and the pier is used to separate the gate hole and support the gate, breast wall, work bridge and traffic bridge.

The bottom plate is the foundation of the lock chamber, which transfers the weight and load of the upper structure of the lock chamber to the foundation and has the functions of seepage prevention and scour prevention. The lock chamber is connected with the upstream and downstream connecting sections and the river bank or other buildings respectively. The upstream connecting section includes: wing walls on both banks and slope protection, scour prevention groove, bottom protection and river mattress layer to guide the water flow into the lock chamber smoothly.
