Abstract
Disclosed is a blockage-proof water diversion and drainage device for highway tunnel construction. The device may include an inlet cleaning component, a diversion component connected to a bottom of the inlet cleaning component, a debris collection component connected to an end of the diversion component close to the inlet cleaning component, and a pre-storage component connected to a bottom of the diversion component. An outlet end of the pre-storage component may be connected to the debris collection component. An openable baffle component and a screen plate may be provided inside a main pipe of the diversion component which can transfer filtered sludge and other debris to the debris collection component, keeping the main pipe clean, maintaining the drainage speed of accumulated water, and reducing the frequency of manual cleaning. Additionally, the device can scrape and clean a surface of the screen plate to prevent blocked, thus extending device maintenance time.
