Hydraulic steel dam technology is a newly emerging type of sluice gate in recent years, which currently holds a large market share in the water conservancy industry. The so-called hinge dam has similarities with a type of water retaining gate called hinge dam, both of which use hydraulic cylinders to support the dam surface, achieve dam raising and water blocking, and dam lowering and flood discharge. But the reason why Heye Dam is so fast is that the North Lord values the unique advantages of Heye Dam, mainly including the following points:

1. The material used for the dam surface of the hydraulic steel dam is low-carbon alloy steel plate. Through structural calculation and analysis, the steel structure panel and driving mechanism can resist any impact of floods, sand and gravel, and large floating objects. The stress conditions are good, sturdy, and the height difference between the front and back of the dam surface is small. It is particularly suitable for cold and water freezing areas, solving the problem of frost resistance and resisting local ice pressure. It has a better solution to the problem of frost heave in frozen areas than concrete structures. Under the frost heave pressure of the ice surface, the sturdy dam body of the hinge dam will quickly release the oil pressure inside the hydraulic cylinder through the mechanical valve assembly device, thereby protecting the hinge dam from damage caused by weak frost heave.

2. The hydraulic cylinder adopts a single acting plunger cylinder, with only one hydraulic pipeline on each dam surface. The hydraulic pipelines are densely arranged downstream for easy maintenance, which can effectively identify oil leakage failure points and failure rates. All other components are configured and easy to replace. The hydraulic oil adopts a low-temperature anti-wear type, and the hydraulic oil tank is equipped with a deep electric heating device to ensure good operation at low temperatures.

3. In the absence of electricity or power source, it achieves automatic dam lowering operation, dam lowering speed control, and ensures high reliability and performance, especially suitable for remote mountainous areas without human presence. The hinge dam is designed with a balanced dam body. When it is not blocking water, the empty dam can also be lowered by manually opening the manual valve located in the control (in the absence of electricity). When the flood level exceeds a certain height of the dam (pre-set), it will cause the hydraulic pressure inside to rise. When it exceeds the set pressure, the mechanical overflow valve will open to release pressure (the opening is controlled by the driver), causing the hinge dam surface to descend and maintain the water level height. When a large flow of flood passes through, the hydraulic pressure will suddenly rise under continuous impact on the dam surface. At this time, the overflow valve (mechanical) will continue to open, and the dam surface will rapidly descend in an orderly manner.

4. The hydraulic steel dam adopts concealed support, low center of gravity, and small foundation drop upstream and downstream of the dam surface, almost like a riverbed. For the renovation of old foundations, the excavation weight is extremely small, which is very suitable for renovation projects involving various types of movable dams and saves civil engineering work. The split and combined design of the hinge dam can effectively solve the problem of excessive torque concentration at the bottom axis of the integrated steel dam gate and the need to follow the length of the single span. The split design of the hinge dam disperses the water flow impact force to each dam surface unit, which can prevent adverse factors such as large floating objects, sediment, debris, and rust from affecting various components. The dam surface is neat and clean, and can be painted with different colors, patterns, slogans, etc. according to the needs of the owner. The dam crest can also be customized with wave shaped, wing shaped and other shapes to create a water carrying effect.

5. The self-control control of hydraulic steel dams is diverse, with remote, remote, and centralized network control, and fully automatic control with on-site manual control. There is an interlocking relationship between the three types, and users can randomly choose one control according to their own needs. Through remote video networks, real-time on-site footage can be transmitted, which can be integrated into water purification monitoring and flood control scheduling of various local water bureaus. At the same time, hydraulic pump stations are also protected by control measures, mainly including hydraulic pressure (including pressure sensors and relays, oil level, oil temperature, oil filter blockage, etc.).

6. Hydraulic steel dams can retain water at any height according to the water storage capacity of the river channel. The dam surface can stay and support within any set angle range, and can also be combined or synchronously adjusted with a single or multiple fans to prevent downstream erosion caused by water flow. All dam surfaces within a few hundred meters can be quickly adjusted to form a horizontal straight line, facilitating integrated modular control to create a beautiful landscape in the paper market river channel.

Hydraulic steel dams are suitable for working conditions with wide gate holes (1-60 meters) and small water level differences (1-7 meters). Due to their wide design, they can eliminate the need for several gate piers, resulting in a simple structure and significant savings in civil engineering investment. Due to the layout of the hoist on both sides of the hoist room, there is no traditional rack or working bridge on the upper part of the gate, which can fully meet the requirements of the landscape and save on civil engineering.

Hydraulic steel dams are mainly used in some hydropower projects, and are also commonly used in urban management work. They are generally classified according to water head, and their engineering design is relatively strict. They are specially made according to the requirements of the construction site, and are relatively hard with good impact resistance. Therefore, this equipment is commonly used in many water conservancy projects, and its working characteristics need to be understood by people.

1. Maintenance aspect

Regardless of the type of hydraulic equipment used, it is important to pay attention to maintenance and upkeep. Hydraulic active dams require annual maintenance and are relatively easy to replace in case of malfunctions. The layout of hydraulic pipelines and all components can be easily and quickly replaced, and oil leakage can be avoided during the replacement process.

2. Equipment performance

This device has good working performance, high strength, and strong impact resistance, and is not afraid of mud and blockage. It is a relatively sturdy and stable device that can quickly complete lifting and lowering actions even when a large amount of sand and gravel are completely buried. It also uses strong force to remove blocked silt or sand and gravel, which does not require manual cleaning, saving a lot of manpower and material resources. Moreover, the recovery speed after river cleaning is relatively fast.

Hydraulic steel dam is a novel, beautiful, and practical type of gate. It has a simple structure, reliable performance, can lift the dam for water storage, collapse the dam for flood discharge, and can also pass water on the dam crest, forming a landscape effect of artificial waterfall; It utilizes nature without damaging it, which can solve the contradiction between urban river discharge and water storage, and is also conducive to the protection of the ecological environment By introducing the structural characteristics of steel dam gates and the features of their opening and closing equipment, combined with engineering examples, this article elaborates on the application of steel dam gates in urban landscape rivers.

The application range of hydraulic active dams is very wide, and they can be used in both the north and south of China. Moreover, this is an automated equipment that has good control and regulation of seasonal water level height, integrating safety, reliability, environmental protection and energy conservation. The investment in construction is also very small, which is not only beneficial for the survival and migration of fish in rivers and other areas.

Hydraulic steel dam 1. Traditional winch lift gate has complex design and layout, and requires extremely high requirements for the dam. It requires the construction of a corresponding winch installation platform, which has extremely high investment costs and a long construction and installation period.

2. The current popular type of water blocking gate is the flap gate. When the garbage and various floating objects (such as branches, aquatic plants, and household waste) in the river pass through the flap gate due to water flow impact, they are easily stuck, causing water leakage or damage when the gate returns to its original position; This type of gate has an opening of about 80 degrees when fully opened, but it still has a certain water blocking ability, which affects the discharge capacity of the gate. Moreover, due to the limitations of structural proportion and weight distribution, the flipping gate cannot be manufactured if it is too high or too high. 3. Rubber dams need to be filled with water during water storage, and water needs to be pumped during water release, which takes a long time throughout the entire process of water storage and release; Rubber dams can easily cause rubber wear when they collide with the dam surface during flood discharge; Branches and wooden stakes in the river can easily puncture the rubber dam when passing through it, seriously affecting its operation; In addition, the characteristic of rubber itself - easy aging, greatly shortens the service life of rubber dams.

The bedridden flap gate is implemented through the following technical scheme: including a door panel, which is set on the concrete dam foundation through a door panel hinge seat. The door panel is connected to a hydraulic cylinder through an oil cylinder connecting shaft, and the hydraulic cylinder is fixed on the concrete dam foundation through the oil cylinder hinge seat. The hydraulic cylinder can rotate between the hydraulic cylinder and the oil cylinder hinge seat. The hydraulic cylinder is connected to the hydraulic control device through a hydraulic oil pipe, and the hydraulic control device is connected to the remote control equipment. The door panel and the hydraulic cylinder form a triangular support structure. The bottom of the door panel is installed with a bottom waterproof rubber.

Bed rest flap gate, suitable for hydraulic and hydroelectric, municipal construction, water supply and drainage, aquaculture, agricultural water conservancy construction, tourism development and other projects.
