Background technique

Water conservancy projects refer to various projects built to control, regulate and utilize surface water and groundwater in nature to achieve the purpose of eliminating harm and creating benefits. Some water conservancy projects need to be constructed in construction holes due to environmental reasons. For diversion of projects in the caves, a diversion and drainage pipe structure is needed.

Install the anti-siltation orifice plate. The anti-siltation orifice plate and the anti-siltation block cooperate with each other to intercept the silt in the drainage, so that the silt will enter the interior of the lower cavity plate through the holes of the anti-siltation orifice plate under the erosion of the water flow, thereby reducing the diversion outflow. The amount of silt in drainage can prevent the back pipe from being blocked due to accumulation of silt and affecting drainage.
