Operating procedures for opening floodgates of reservoirs


1. Normal flood discharge: rainfall in the reservoir area, flood peaks in the upper reaches of the reservoir, downstream rivers


In order to ensure the safety of the downstream floods, the flood is blocked and the peaks are shifted.


After the peak, the reservoir opened the gate to release floods, creating a barrier for the next time the dam intercepts the flood peak.


The normal flood discharge.


2. Normal flood gate operating procedure:


1. Call the Municipal Water Conservancy Bureau and the Municipal Defense Office, and notify Honghuagang after obtaining consent


District Water Conservancy Bureau and District Flood Control Office, and please assist in patrolling the urban river


Open the floodgate according to the instructions of the superior.


2. When discharging the flood, first use the discharge gate to discharge the flood.


During flooding, the bottom outlet gates for flushing sand are used for flood discharge. Both gates are gradually enlarged.


Flood discharge in principle, and the dispatch time should be extended as far as possible when conditions permit.


Three abnormal flood discharges: there is no rainfall in the reservoir area, and no flood peaks are generated upstream into the reservoir.


Due to the high water level of the reservoir or other reasons, the need to open the sluice flood discharge is abnormal flood discharge.


Four principles to be observed in abnormal flood discharge:


1. To regulate the water level of the reservoir area or improve the water quality of downstream rivers and supplement the river ecology


Water must be notified to Honghuagang District Water Conservancy under the instructions of the Municipal Water Conservancy Bureau and the Municipal Defense Office


Bureau and District Flood Control Office, and please assist in patrolling the urban rivers, and then according to the superior


Instruct to open the gate and adjust the water.


2. The opening and diversion of water should be dispatched within the allowable time range, and the water should be discharged


The gate is gradually enlarged, and it is arranged to be implemented late at night.
