Hydraulic steel dam is one of more than 20 types of gates produced in
the project. It is a steel dam gate with hydraulic system opening and
closing, which is also called hydraulic steel dam for short.
液压钢坝泄洪能力强，活动坝面放倒后 只高出基础平台20厘米左右 达到无坝一样的泄洪效果 即使是千年一遇的特大洪水
The hydraulic steel dam has a strong flood discharge capacity. After the
movable dam surface is put down, it is only about 20 cm higher than the
foundation platform to achieve the same flood discharge effect without
dam. Even the once-in-a-thousand-year flood will not cause damage to the
dam body. In the case of no power and no power source, the dam can be
lowered automatically, and the empty dam can also be lifted and lowered
freely. Only the manual valve of the oil system needs to be opened
manually. This function makes the safe flood discharge of some rivers
with special flood discharge requirements under severe weather
conditions, such as heavy rain, significant and highly controllable.
When the flood level exceeds a certain height of the dam crest (can be
set in advance), the pump station will start to work, making the
hydraulic movable dam surface drop, ensuring the safety of flood
discharge; the hydraulic dam can be adjusted arbitrarily according to
the water storage capacity of the river At the same time, it can realize
any combination or synchronous adjustment of single or multiple dam
fans to reduce the scour of the downstream.
