Hydraulic lifting dam and its characteristics

The hydraulic lifting dam adopts a hinged design and is connected to the embedded parts of the dam surface through double fulcrums or multiple fulcrums. The dam foundation on the opposite side of the door plate is provided with an oil cylinder with an opening and closing door, which is used to open the gate for flood discharge or close the gate to store water. In the normal water storage state When the dam is dammed, the support rod can be used for auxiliary support, or the oil cylinder can be used for direct support. Wide range of application fields, such as irrigation, ship locks, fishing grounds, sea water tide blocking, urban river landscape engineering and small hydropower stations. Compared with the gate and ordinary gate, the number of buttresses and hoisting platforms can be reduced. It has high safety and is a relatively popular river building at present. After completion, the water storage is beautiful, and the waterfall landscape effect is obvious.

The Hydraulic Elevator Dam is used as a new type of flap gate. It adopts a double triangular stable structure and a scientific and reasonable mechanical structure. It is assembled with infinite width, and there is no need to set piers between the plates, which is suitable for rivers of different widths. The bottom of the board is used as the hinge axis, and it is close to the river bed after it collapses, and the flood discharge effect is good, and it is not affected by sediment deposition and floating objects; factory-assembled design, quality assurance, fast construction, single gate or full gate In operation, any floating object can quickly rush downstream at the designated position, scour and silt, scour and silt, zone control, fast water release, without affecting flood control safety, especially suitable for mountainous and urban rivers with rainy and rapidly rising floods in the south. On the basis of overcoming the main defects of the conventional movable dam type, the hydraulic lifting dam retains its own advantages:

(1) The sluice is sturdy and durable;

(2) It has the characteristics of being close to the river bed and not blocking water;

(3) It has the characteristics of quick release of water from the flap gate dam and water retention at any height;

(4) It has the characteristics of beautifying the landscape of the steel dam gate.

In short, the hydraulic lifting dam overcomes various shortcomings of the traditional movable dam, retains all the advantages of the four types of movable dams, has obvious advantages, and is a cost-effective movable dam type.

Why is the hydraulic lifting dam getting more and more attention?

1. In fact, a very important reason is the relatively low cost. Compared with some dams of the same size, the surface can be moved, so the upper width of the foundation is only required to be equal to the height of the active dam. Therefore, the overall project investment cost is relatively low.

2. The hydraulic lifting dam has a high degree of automation. It adopts buoy switch control and operates the hydraulic system to realize unmanned management. According to the flood fluctuation, the movable dam surface can be automatically lifted and lowered.

3. The hydraulic lifting dam is firm and reliable in structure and has a long service life. After the dam surface is raised, a stable supporting pier structure and fixed triangular supports are formed. It will not be damaged by freezing in winter in the north, and its service life is more than 50 years.

4. The dam is beautiful in shape. The artificial waterfall dam can be designed in an arc shape. It can be operated manually, and the movable dam can be raised and lowered at will, so that the artificial waterfall can generate a dynamic mode. It can be used as a new tourist attraction and a high-tech scenic spot in the world. It must be attractive to tourists. .

5. The sealing effect is good, and the maintenance and management cost is low. The sealing water stop of the hydraulic lifting dam is an important innovation, not only can almost drip water, but also can be used for ten years. Parts are durable, easy to replace and low cost.

6. The flood discharge capacity of the hydraulic lifting dam is very good. Its dam surface is about 20 cm higher than the foundation, so it feels different, but when the water volume is large, it will not affect flood control or shipping.

The construction of a dam usually takes a long time to ensure that the dam's water storage function and flood discharge function can be used normally when necessary. However, traditional dams still have shortcomings such as long construction period and complicated construction. In comparison, hydraulic lifting dams are much better.
