Pond water intake is generally controlled through a water gate to control the flow of water through the water pipe into the pond. Divide gates are generally groove inserts. In many places, embedded PVC elbows are used to control the inlet of the pond. This method has good anti-leakage performance and simple operation. The bottom of the inlet pipe of the pond should generally be flush with the bottom of the inlet channel. When the bottom of the channel is high or the pond is lower, the inlet pipe can be lower than the bottom of the inlet channel. The height of the center of the inlet pipe should be higher than the surface of the pond, and it is better not to exceed the maximum level of the pond. A pocket net should be installed at the end of the inlet pipe to prevent fish in the pond from entering water pipes and debris into the pond.
Each pond is generally provided with a drainage well. The drainage well uses a gate to control the discharge of water, and can also be controlled by a gate or extubation. The extubation drainage method is easy to operate and has good anti-leakage effect. Drainage wells are generally cement-brick structures with grooves, gates, and other grooves. The drainage of ponds enters the drainage channels through drainage wells and drains, and a number of drainage channels are collected into the total drainage channel. Drainage gates should be constructed at the end of the total drainage channels.
The depth of the drainage well should generally reach the bottom of the pond, and it is better to drain all the pond water. In some areas, due to problems such as high external water level or construction cost, the drainage well is built in the middle of the pond and only discharges about 50% of the water in the pond. The rest of the water needs to be lifted by power. The depth of the drainage well should not be higher than the pond. The middle part.
