The utility model discloses a water-gas separation device for a gas tunnel. The tail end of the longitudinal drain pipe is connected with the gas-water separation chamber; the gas-water separation chamber is separated from the drainage compartment through the arranged middle partition plate; a U-shaped pipeline is arranged in the middle partition plate, a water inlet of the U-shaped pipeline facesthe gas-water separation chamber, a water outlet of the U-shaped pipeline faces the drainage compartment, gas and water discharged into the transverse drainage pipe can be effectively separated and prevented from accumulating in the center drainage pipe, and the hidden danger that gas accumulates in the drainage pipeline in the tunnel operation period is avoided. The whole structural device is simple and reliable in design and convenient to use. 本实用新型一种瓦斯隧道水气分离装置，纵向排水管末端与气水分离室相连，通过所设置的中隔板将气水分离室与排水隔室隔开，在中隔板内设置有U型管道，U型管道的进水口朝向气水分离室，出水口朝向排水隔室，可以有效将排入横向排水管中的瓦斯与水分离开，避免积聚在中心排水管中，解决隧道运营时期的瓦斯在排水管道中积聚隐患。整个结构装置设计简单，可靠，且使用方便。
