A drainage structure for water conservancy engineering construction

Abstract

This utility model relates to the field of drainage technology in water conservancy engineering construction, and discloses a drainage structure for water conservancy engineering construction, including a drainage pipe. A filter screen is installed inside the drainage pipe, and a guide pipe is installed on the side wall of the drainage pipe. Shells are installed on both sides of the drainage pipe. An inlet is opened on one side of the drainage pipe, and an outlet is opened on the other side. A check valve assembly is installed inside the drainage pipe, and a disassembly assembly is installed inside the shell. The check valve assembly includes a rubber plug, the outer wall of which is slidably connected to the inside of the inlet and the inside of the drainage pipe. In this utility model, when water flows in from the inlet, the water pressure pushes the rubber plug to move, which in turn moves the sliding column. At this time, a spring is compressed, and the outer wall of the sliding column slides within a limiting column, opening the valve and allowing water to flow smoothly, preventing backflow and achieving an adaptive pressure regulation effect, thus improving drainage efficiency.
