16. A method for regulating and controlling water flow of a retaining dam comprises the following steps:
s1 water storage: when water needs to be stored, a worker can press outside air into the ventilation cavity by operating the air compressor, the air pressure in the ventilation cavity rises, and the original water in the ventilation cavity is discharged through the water outlet; the other mode is that when water needs to be stored, a worker can discharge the water body in the air exchange cavity through a drainage pump on the water exchange part, due to the atmospheric pressure, outside air enters the air exchange cavity along with the air inlet, the buoyancy of the gate is increased, the gate rises, and water storage starts;
s2 flood discharge: when flood discharge is needed, workers can suck out air in ventilation through the air compressor, the air pressure in the ventilation is reduced, the air in a foundation pit of the dam body flows back along the water outlet and flows into the ventilation cavity, the buoyancy received by the gate outside the ventilation cavity is reduced, the gate begins to fall down for flood discharge, and the workers can control the proportional valve to control the opening size of the channel of the exhaust pipe and control the gas loss speed in the gate in the process so as to control the flood discharge speed of the gate; the other mode is that, when flood discharge is needed, a worker can send water through the ventilation cavity of the water pumping pump box, internal gas is discharged along the exhaust port along with the entering of water flow in the ventilation cavity, the buoyancy force borne by the gate is reduced, and the gate descends to start flood discharge.
