Hydraulic flushing gate reservoir flush system can fully utilize the pipeline's potential capacity for storing wastewater; utilize the stored wastewater for flushing pipes; flexibly control wastewater of different qualities based on water quality conditions. The installation position of the flush gate reservoir is determined by the wall structure of the structure. The retaining gate can be locked by means of a pivot rotation.

Operation process as follows:
Divide the rainwater storage pond into multiple flushing channels. Then, in each channel, isolate a single storage chamber for storing incoming water during the daily inflow into the pond. This serves as the flushing water source for cleaning the pond. When pollutants settle at the bottom of the pond and require cleaning, empty the rainwater storage pond and initiate the hydraulic system through the PLC control system. Open the flushing door before the storage chamber and begin cleaning the channel.

Hydraulic Flush Door; Retaining Pond Gate Flush
The device, through the retention function of the retaining gate, can fully store wastewater in the potential capacity of the pipeline; it uses stored wastewater to flush the pipeline; flexible control of wastewater with different water qualities is implemented based on water quality conditions. The installation position of the retaining gate flush is determined by the wall structure of the structure. The retaining gate rotates at a pivot and can be locked at any position. When idle, the retaining gate can be locked in a wider open position; when storing water, the retaining gate is locked in a closed position, sealing with the bottom of the pipeline to retain wastewater. The designed retaining gate can be set for *outflow or bottom outflow. Retention pond flush valve, retaining shield flush hydraulic flap gate

Made of stainless steel, sturdy and durable; one-time flush length of 10

Main Functions and Application Range:
Large Tri-Formaldehyde Intermediate Wash】Primarily used for oil washing and maintenance of drainage pipelines with larger diameters, such as wastewater or combined sewers, canals, rectangular ditches, etc. Additionally, it can serve as a management facility for the entire pipeline network or section by utilizing the potential capacity of the pipeline through the retention gate's retention function. The hydraulic flushing gate is mainly installed in rainwater storage ponds or canals, providing automatic flushing for sediment at the bottom. It features long-lasting operation.

Rainwater storage ponds are typically fully underground structures with considerable depth. These ponds operate for fewer days throughout the year, serving as storage during rainfall only. Therefore, the operational mode of newly constructed rainwater storage pond systems is usually unattended or minimally attended with regular inspections. China has developed its technology in rainwater storage relatively late, and the early rainwater storage ponds mainly had the function of "storage" without the "adjustment" or "utilization" capabilities, which urgently needs updating or supplementing.
Rainwater retention ponds are typically connected to municipal stormwater wells for the collection and storage of rainwater; they are equipped with drainage pumps and level gauges. The drainage pumps are connected to the municipal stormwater system via drainage pipes to empty the retention pond during rainfall events. The level gauges are used to indicate the water level within the retention pond. Current technology relies on manual on-site operations for the management, utilization, and control of rainwater retention ponds. Given their widespread distribution in urban construction, often built underground, and unclear responsibilities—whether they belong to the municipality or property management—the manual management is not only challenging but also costly. Moreover, since the retention function of the ponds is predicated on emptying them before heavy rain, with their widespread and numerous locations, it is difficult to monitor and empty them within a short time frame upon receiving heavy rain warnings. It is nearly impossible for manual labor to effectively manage the retention ponds in such a short interval, leading to inadequate management and delayed responses. Furthermore, on-site operations require trained workers, which adds to labor costs. If the retention ponds cannot be effectively emptied before heavy rain, their flood mitigation function is compromised, increasing the likelihood of urban flooding.
