Anti-backflow water seepage device
The invention provides an anti-backflow water seepage device. The anti-backflow water seepage device comprises a seepage well outer pipe, an anti-backflow outer cylinder is arranged on the upper middle portion in the seepage well outer pipe, the cylinder wall of the anti-backflow outer cylinder is tightly connected with the pipe wall of the seepage well outer pipe, an anti-backflow inner cylinder with the upper end sealed is arranged in the anti-backflow outer cylinder, a gap exists between the anti-backflow outer cylinder and the anti-backflow inner cylinder, a water return opening is formed in the cylinder bottom of the anti-backflow inner cylinder and communicates with the anti-backflow inner cylinder and the anti-backflow outer cylinder, an upper water return pipe is arranged at the water return opening and located in the anti-backflow inner cylinder, the top end of the upper water return pipe is higher than the cylinder bottom of the anti-backflow inner cylinder, And a one-way overturning cover plate is arranged at the top of the upper water return pipe; a lower drainage pipe is arranged on the anti-backflow inner cylinder and communicates with the lower portion of the seepage well outer pipe, and water permeable holes are formed in the lower portion of the seepage well outer pipe. The anti-backflow water seepage device has the beneficial effect that the problem that when the underground water level of a seepage well is too high, the backward flowing phenomenon is likely to happen can be effectively solved.
本发明提供一种防倒灌渗水装置，其包括渗水井外管，渗水井外管的管内的中上部设置有防倒灌外筒，防倒灌外筒的筒壁与渗水井外管的管壁紧密连接，防倒灌外筒的筒内设置有上端密封的防倒灌内筒，且防倒灌外筒与防倒灌内筒之间存在间隙，防倒灌内筒的筒底设置有返水口，返水口连通防倒灌内筒与防倒灌外筒，返水口处设置有上返水管，上返水管位于防倒灌内筒筒内，且上返水管的顶端高于防倒灌内筒的筒底，上返水管的顶部设置有单向翻转盖板；防倒灌内筒上设置有下排水管，下排水管与渗水井外管的下部连通，渗水管外管的下部设置有透水孔。本发明的有益效果在于其能够有效解决渗水井在地下水位过高时容易产生倒灌现象这一问题。
