[0002] At present, in the construction of highway tunnel projects, for the construction of water-rich sections of tunnels, it is necessary to continue to pay attention to and strengthen the drainage construction in the tunnel. The existing conventional drainage is mostly to directly set up drainage ditches or water collection tanks. However, as various requirements become higher, the drainage process needs to pay attention to environmental protection measures. For this reason, there is an urgent need for a special water collection tank that can achieve reliable water collection in the tunnel and meet environmental protection emission requirements to solve the above problems.

[0003] A Chinese patent with application number CN202223149254.9 discloses a movable temporary water collecting tank, including a box body and a fixed frame, the box body is provided with a water collecting chamber, one end of the box body is provided with a box opening, a partition is fixedly arranged in the water collecting chamber to separate the water collecting chamber into a sewage tank and a clean water tank, one end of the partition away from the bottom of the water collecting chamber is lower than the box opening, one end of the box body away from the box opening is fixedly connected to one side of the fixed frame, and universal wheels are arranged around the other side of the fixed frame.

Impurities are precipitated in the sewage tank, but the sewage flowing into the clean water tank may still contain impurities floating in the sewage, which will result in poor sewage treatment effect. Moreover, if there is sufficient water in the tunnel, impurities may flow into the clean water tank before being precipitated in the sewage tank. This cannot meet the needs of construction in areas with high environmental protection requirements. Utility Model Content
