Flexible anti-seepage device for gasoline station

The invention discloses a flexible anti-seepage device for a gasoline station. The flexible anti-seepage device for the gasoline station comprises a buried storage tank and a sacrificial anode arranged at the periphery of the buried storage tank, wherein the sacrificial anode is connected with the wall of the buried storage tank by virtue of an explosion-proof connection box; a gasoline sac is arranged in the wall of the buried storage tank, a thin film mounting ring piece is arranged at an opening of the gasoline sac and is arranged between a manhole cover plate and a manhole ring piece of the buried storage tank, and a breathing hole is formed above the wall of the buried storage tank. Compared with the prior art, the flexible anti-seepage device for the gasoline station has the beneficial effects that the sacrificial anode is adopted for carrying out cathode protection on the buried storage tank, an external power supply is not needed, investment is saved, protection effect is good, maintenance and management are simple, the service life of the buried storage tank is greatly prolonged, and corrosion risk, caused by corrosion of the outer wall, of the buried storage tank is reduced; and external corrosion of a buried gasoline storage tank of the gasoline station in various soil mediums can be effectively prevented, the life of the gasoline storage tank is greatly prolonged, and risk of leakage of an oil product is reduced.
