Characteristics of hydraulic dams and their scope of application

Hydraulic lifting dams, also known as hydraulic dams. Hydraulic lifting dams are revolutionary achievements in water conservancy technology, and their movable dam technology is relatively advanced in the world. Compared with traditional sluice gates and rubber dams, hydraulic lifting dams have obvious characteristics and wide applications. Let us briefly introduce the characteristics and scope of application of hydraulic lifting dams.

1. Characteristics of hydraulic lifting dams:

1. Simple structure and flexible operation.

The dam body of the hydraulic lifting dam has a large span, simple structure, reliable support, and convenient construction. The hydraulic lifting dam has a flexible operating system, uses buoy switch control, and is automated.

2. Superior water conservancy conditions.

Hydraulic lifting dams have special advantages in water conservancy. While basically maintaining the original riverbed, it can also prevent floating objects such as sediments and pebbles from accumulating on the upstream of the riverbed, hindering drainage, and making flood discharge unobstructed. Compared with traditional gates and rubber dams, it has a larger flow capacity and leakage flow. Therefore, hydraulic lifting dams are particularly suitable for some areas with many stones, sand, trees, and relatively cold weather that are not suitable for building rubber dams. In addition, the hydraulic lifting dam can also adjust the dam height overflow as needed to control the upstream water level and leakage flow.

3. Small project, short construction period, save money.

Compared with traditional sluice gates, the construction work of hydraulic lifting dam is relatively simple, the construction period is relatively short, and the amount of work is relatively large, which saves construction costs in a certain sense.

4. Long durability.

The hydraulic elevator dam has good durability. Only by properly maintaining the fan structure and hydraulic system of the hydraulic lifting dam can it obtain longer durability than the rubber dam.

5. Strong structure and strong impact resistance.

The mechanical structure design of the hydraulic lifting dam is very scientific. After the dam surface is raised, an extremely stable pier dam support structure can be formed. There is no need to set up supporting piers in the river, so there are no waterproof objects. After the movable dam surface of the hydraulic lifting dam is lowered, the dam body is only 25cm higher than the original dam top, and the flood discharge effect can reach the same level as that of the non-hydraulic lifting dam. In the flood season, any objects on the riverbed cannot be seen, which can prevent flood control and shipping.

6. Beautiful shape, known as an artificial waterfall.

The dam body of the hydraulic lifting dam adopts an arc design. Generally speaking, the dam height below 5 meters is a reinforced concrete dam surface, and the dam height above 5 meters is an arc-shaped steel gate, which can be adjusted at will. When the water volume in the upstream riverbed is large, an artificial waterfall or water curtain spectacle will be formed, allowing tourists to stop and watch.

2. Application scope of hydraulic lifting dam.

Since the active interception height of the hydraulic dam exceeds 10 meters, the width is unlimited, and it is not affected by sediments and floating objects, it is basically suitable for riverbeds of all geological conditions. Therefore, it is widely used in agricultural irrigation, hydropower generation, beautification of urban environment and other fields.
