Description

A large sluice engineering pier

technical field

The utility model relates to a large-scale sluice engineering pier.

Background technique

Sluice engineering is a hydraulic structure built on rivers, channels, lakes, and seaports, using gates to control flow and adjust water levels. It is widely used in water conservancy projects. When the sluice gate is closed, it can block floods, block tides, store water and raise the upstream water level to meet the needs of upstream water intake or navigation; when the gate is opened, it can discharge floods, drain waterlogged water, wash sand, draw water, or adjust the flow according to the needs of downstream water use.

The sluice is composed of a lock chamber, an upstream connecting section and a downstream connecting section. The sluice chamber is the main body of the sluice, which is equipped with a bottom plate, a gate, a hoist, a gate pier, a parapet, a working bridge, a traffic bridge, etc. The gate is used to block water and control the flow through the gate, and the gate piers are used to separate gate holes and support gates, parapets, working bridges, traffic bridges, etc. The bottom plate is the foundation of the lock chamber, which transmits the weight and load of the upper structure of the lock chamber to the foundation, and has the functions of anti-seepage and anti-scouring. Due to the complex shape and high flow velocity of the water flow through the gate, the shape design of the gate pier often has a certain influence on the flow state of the water flow through the gate. At present, for the design of the gate pier, the pier head is generally designed in a semicircular shape because it is the part facing the water, and the pier tail of the gate pier is generally designed in a semicircular, square and streamlined design.

During the actual operation of the sluice, we often find that the design of the tail of the sluice pier is square or semicircular, so that the water flow cannot be well diffused after passing through the sluice sluice chamber, and the water flow has a large range of water behind the pier. In the vortex area, under the extrusion of the vortex, the water flow out of the gate is unstable and fluctuates greatly, and the flow state of the water flow in the stilling pool is relatively unfavorable. The strength of the vortex increases with the increase of the local opening degree. The state of the sluice has a great impact on the safety of the sluice itself. Due to the unstable water flow, the pulsating pressure on the bottom plate of the stilling pool is relatively large, causing the instability of the bottom plate.

In order to improve the water flow pattern behind the pier tail of the sluice pier, an improved streamlined pier tail type was proposed. After model tests, this type of pier tail can indeed effectively improve the water flow state of the stilling pool, but after The actual engineering test shows that this body shape has some disadvantages, such as the streamlined tail tip is difficult to construct, and because the tail tip is thin on the concrete structure, it cannot be reinforced, which will cause damage under the impact of water flow and affect the normal operation of the project. .
