Self-flowing drainage pressure-limiting anti-floating structure

The utility model discloses a self-flowing drainage pressure-limiting anti-floating structure which is an active anti-floating structure composed of a permeable system, a water collecting system, a drainage system and a monitoring control system. The permeable system filters soil particles in a soil layer to enable pressure water to be gathered into the water collecting system, the pressure water is guided into the drainage system, the monitoring control system regulates drainage in real time according to the relation between resistance and water buoyancy and the floating displacement of a base, the pressure water head of the base is controlled, gravity flow pipelines are arranged according to the altitude difference of site terrain, and the water is drained into a municipal pipe network or a reservoir. The anti-floating structure is arranged outside a waterproof layer of an underground building, construction and maintenance are convenient, and dynamic balance of water buoyancy and resistance is achieved.
