The flood discharge energy dissipation buildings of the hydraulic engineering mainly comprise overflow dams (roads), plunge pools, discharge tunnels, hydraulic gates and the like, bear huge high-speed water flow impact force when a hydropower station runs to discharge flood, and a concrete bottom plate of the buildings is very easy to be damaged by scouring, cavitation erosion, abrasion, vibration damage, bottom plate splitting, cracking and the like. After the bottom plate is damaged, huge water flow impact can continuously wash the building foundation, and the dam foundation can be directly damaged seriously. According to statistics, nearly 40% of flood discharge energy dissipation buildings of hydraulic engineering at home and abroad are damaged to different degrees, such as Libby in the United states, Sayano-Shushenskaya in Soviet Union, and energy dissipation protection facilities of hydropower stations such as Wuqiangxi, fishponds, temples and the like in China are damaged.

Intelligent water stopping method for repairing underwater concrete damaged dry chamber
(1) The whole equipment for repairing the damaged underwater concrete dry land sinks, and the rubber water stops primarily
Firstly, transporting the equipment for repairing the damaged underwater concrete dry land to a repairing site, lifting the equipment to a repairing site, and then slowly sinking the equipment into the water, wherein in the process, the intelligent monitoring and control center controls the waterproof electromagnetic valve to be basically in a closed state, so that the water cannot enter a first-stage water pumping cabin, a second-stage water pumping cabin and a third-stage water pumping cabin, the whole water pumping cabin is in a emptying state, certain buoyancy can be generated, and the load force of lifting equipment is effectively reduced. However, if the device for repairing the damaged underwater concrete dry land is unbalanced in the sinking process, the intelligent monitoring control center can open and close the adjusting water pump to fill water in the pumping cabin to different degrees so as to realize the effect of adjusting balance.
And secondly, in the sinking process, real-time accurate positioning is carried out through a satellite positioning system, and the underwater concrete damage dry land repairing equipment is accurately sunk to a preset position. And then, the intelligent monitoring control center controls the waterproof electromagnetic valve to be opened, so that part of water flow enters the first-stage water pumping cabin, the second-stage water pumping cabin and the third-stage water pumping cabin. At the moment, the rubber water seal (first-stage P-type water seal, second-stage omega-type water seal, third-stage omega-type water seal and fourth-stage I-type water seal) is compressed under the action of the dead weight of the underwater concrete damage dry repairing equipment and the hydraulic pressure, and after the rubber water seal is compressed to a preset compression amount, the preparation work in the step (2) is carried out.

(1) the whole equipment for repairing the damaged underwater concrete dry land sinks, and the rubber water stops primarily
Firstly, transporting the dry land repair equipment for the underwater concrete damage to a repair site, lifting the repair equipment to a repair site, and then slowly sinking the device underwater. In the process, the intelligent monitoring control center 7 controls the waterproof type electromagnetic valve 6 to be basically in a closed state, so that water cannot enter the first-stage water pumping cabin 5, the second-stage water pumping cabin 8 and the third-stage water pumping cabin 9, the whole water pumping cabin is in an emptying state, certain buoyancy can be generated, and the load force of the lifting equipment is effectively reduced.

at the moment, the intelligent monitoring and control center starts the water level monitoring sensor, starts the external drainage pump according to the feedback information of the water level monitoring sensor, and enters the water pumping cabin through the water inlet hole of the water pumping cabin, namely the first-stage water pumping cabin, the second-stage water pumping cabin and the third-stage water pumping cabin, water in the water pumping cabin is basically pumped out, when the water level drops to zero, the water level monitoring sensor feeds back information to the intelligent monitoring and control center, the intelligent monitoring and control center closes the external drainage pump, and water pumping is stopped; the water level monitoring sensor continuously works to monitor the water level change in the cabin body in real time, and when the water level reaches the water pumping preset water level of the external drainage pump again, the operation is repeated to pump away the water in the water pumping cabin body in real time;
thirdly because the effect of one-level P type stagnant water, second grade omega type stagnant water, tertiary omega type stagnant water, get into one-level pumping chamber, the second grade pumping chamber, the water in tertiary pumping chamber reduces step by step, in addition extract the pumping under-deck water in real time, and the combined action of level four I type stagnant water, water pressure behind the rubber stagnant water is reduced by a wide margin, and then to a great extent reduced get into the damaged dry land of concrete repair under water and equip this internal water, thereby it provides good guarantee condition and sufficient time to establish dry construction environmental condition in this body to repair for the damaged dry land of concrete under water and equip.
9. The intelligent water stopping method for repairing the underwater concrete damaged dry chamber cabin according to claim 6, wherein the step (3) specifically comprises the following steps: in the operation process of the whole device, the underwater camera shoots and records the condition in the pumping cabin in real time, and feeds video information back to the intelligent monitoring control center, and the intelligent monitoring control center can transmit the video information to the remote monitoring, remote control and visual terminal in real time through the underwater signal transmitter, so that real-time information interaction is realized.
