The gate is made of steel, and its surface is treated with hot-sprayed zinc, which is corrosion-resistant, strong and durable. The moving parts are made of special composite materials, and no lubricating oil is required when operating underwater. The gate is opened and closed by hydraulic equipment at high speed, which can be completed in a few minutes. The special locking device can effectively control the opening angle of the gate, and the water level can be adjusted at will.
The hydraulic dam is suitable for working conditions with wide gate holes (1m-60m) and small water level differences (1m-5m). Because it can be designed to be very wide and save several gate piers, it is not only simple in structure, but also saves a lot of civil engineering investment.
Since the hoist is arranged on both sides of the lifting room, the hoist is arranged on both sides. The upper part of the hydraulic steel dam does not have the traditional curved frame and working bridge, which can fully meet the landscape requirements and save civil engineering investment.
The hydraulic steel dam adopts mechanical locking. When the dam collapses, raises the dam and adjusts the water level, any angle can be locked. The surface of the hydraulic steel dam will not move. The thermal spraying of zinc is carried out according to the manufacturing standards of steel gates used for water conservancy and hydropower generation. It is used for water conservancy and hydropower generation. The adhesion is very strong. The research results of authoritative institutions show that the speed of sand is 8≤M/s, which will not damage the zinc layer. The speed of general rivers cannot reach this speed.
The hydraulic dam is a special structure and a special dam gate form. It has no bottom gate groove and side gate groove. It is a structure that the gate blade rotates around the bottom axis. The upstream water stop is pressed on the circular axis. When the dam is up or down, the water stop cannot be separated from the surface of the circular axis. The water stop state is always in a sealed state. The same principle of the side water stop is the same. The water stop will not leave the side chest wall, so the silt deposition will not affect the raising and lowering of the steel dam and the collapse of the dam.
