The successful development of the hydraulic dam is a major reform of the entire steel gate industry, it has obtained two patents, has reached the world advanced level. One. Compared with the rubber dam hydraulic dam: Advantages rubber dam is that time is short, save material, no water blocking, but the rubber dam through ten years of operation, found that life is short, usually 10--12 years to be replaced every 2 --3 years need regular repair and maintenance, the need cofferdam only delayed the operation and consume a large amount of manpower and resources. Poor security, easy to destroy floating upstream and human factors. II. Hydraulic dam flat compared with the flat Gate Gate is widely used at home and abroad, the advantage is safety. However, large investment, long construction period. Concrete piers must generally be between 10 and 20 meters. Seriously affect the flood requirements, the need to widen the river transformation. Third, compared with the flap hydraulic dam gates: flap gate prices low, but to turn on the water when the flood gates need to turn, sometimes floating debris stuck, turn does not move in normal water, there will be automatic gate turn open, it is easy to cause casualties and property losses, especially in the South more floating in the river, this phenomenon is even more serious, in addition, flap gates retaining a low height. Advantages of hydraulic dam: 1, no pier, no need to change the width of the river, when the dam collapsed completely suppressing the concrete foundation can reach flood requirements, no water blocking. 2, when the dam collapsed entirely lodging on the floor, so it will not be subject to any floating debris and vandalism. 3, the top of the dam to allow the hydraulic 0.5-1.0 meters over the water, it would not cause damage to the hydraulic dam when the dam collapsed. 4, can be synchronized ups and downs, there will not be stuck floating debris and other shortcomings. 5, easy maintenance, no maintenance cofferdam, does not affect the operation of the hydraulic dam, a low cost. 6, the hydraulic cylinders in the dam will run back to the original position, stand behind the automatic support from, play a supporting role, so to extend the service life of the cylinder. 7, is particularly suitable for rugged mountain river, river sediment and typhoons more and more areas, even in areas mudslides can occur. 8, life of up to 30 - 50 years.
