Hydraulic lifting dam It is the current world water conservancy construction technology, which has made much progress compared with traditional products. Right now Hydraulic steel dam When replacing the traditional dam, we will see more Hydraulic dam The existence of the manufacturer. Why are hydraulic dams so popular? The following is an overview of the hydraulic dam for your understanding.
The hydraulic lift dam is a movable dam that adopts the mechanical principle of dump truck and combines the hydraulic structure of buttress dam, and has dual functions of water retaining and drainage. It is structurally divided into dam surface (arc or straight), hydraulic rod, hydraulic cylinder Hydraulic pump station , support rod. The hydraulic cylinder is used to directly lift the back of the movable retaining dam surface with the bottom as the axis to achieve the lifting operation for water retaining or flood discharge. The support part supports the back of the active dam face against the sliding support rod, and the structure is stable. Manual push rod switch is used to control operation Hydraulic system According to the flood fluctuation, the movable dam surface is raised and lowered manually.
With the above design operation, it is convenient and simple in practical application, but this Water science and technology It is not simple. The hydraulic lift dam has a scientific mechanical structure, does not block water, and is not afraid of silt deposition; Not affected by floating objects. It is widely used in agricultural irrigation, fishery, ship lock, seawater tide blocking, urban river landscape engineering and small hydropower station construction.
The dam is placed quickly without affecting the safety of flood control; Stable supporting structure, strong ability to resist flood impact; When the dam is lowered, the floating objects in the upstream can be easily washed away, making the river clear. The hydraulic lift dam overcomes the shortcomings of the traditional movable dam type, and at the same time, it has all the advantages of the traditional dam type: the rubber dam is close to the river bed without blocking flood discharge, and the hydraulic dam is more effective and convenient; The flap gate dam automatically releases the dam for flood discharge, and the hydraulic dam can maintain the water level at will. It is also as sturdy and durable as a sluice.
Unlike traditional sluices and rubber dams, hydraulic steel dams have obvious characteristics and wide applications. Here is a brief introduction to this product: first, it has solid structure and strong impact resistance. Mechanical structure design is very scientific. After the dam surface is raised, an extremely stable pier dam support structure can be formed. There are no water blocking objects. After the movable dam surface is lowered, only 25 cm, the flood discharge effect will not be affected. In the flood season, there is no barrier in the river, which can prevent flood control and navigation from being affected.
Hydraulic dam also has good durability. Only the normal maintenance of the sector structure and hydraulic system of the hydraulic lift dam can obtain a longer durability than the rubber dam. Simple structure and flexible operation. The operating system of the hydraulic dam is relatively flexible and can be operated automatically. Moreover, it has simple structure, reliable support and is relatively easy to build.
Of course, the important thing is the superior water conservancy conditions. While basically maintaining the original riverbed, it can also prevent sediment, pebbles and other floating objects accumulated in the upstream of the riverbed from blocking drainage, so as to ensure smooth flood discharge. It has large overcurrent capacity and discharge capacity. Therefore, it is especially suitable for hydraulic lift dams in areas with heavy sediment, trees or relatively cold conditions that are not suitable for building rubber dams. Cost is the best choice for people. Compared with the traditional sluice, the construction work of the hydraulic lift dam is relatively simple, so the construction period is relatively short and the work quantity is relatively small, which saves the construction cost in a certain sense.
The beautiful, arc-shaped hydraulic dam can be painted with color patterns on the dam surface, and the height can be adjusted at will to facilitate creativity. It can also be used as a man-made waterfall or a spectacle of water curtain. Hydraulic lift dam is the result of technological innovation, and naturally it is the best choice for various water conservancy projects.
