Abstract

The invention discloses a foundation pit air film rain-proof device, which comprises a construction area arranged on one side of a road, a rain-proof unit, a drainage unit and a filtering assembly, wherein the rain-proof unit comprises an air film body arranged above the construction area and used for shielding rain in the construction area, a rainwater collecting pool arranged in the foundation and used for collecting rainwater sliding from the air film body, the drainage unit comprises a water guide assembly used for guiding out the rainwater sliding from the air film body, and the filtering assembly is arranged between the water guide assembly and the rainwater collecting pool and used for filtering the rainwater before entering the rainwater collecting pool. After falling the air film body through the rainwater, the rainwater slides down into the water guide assembly along the air film body, and after the water guide assembly guides the rainwater into the filter assembly to be filtered, the rainwater enters into the rainwater collecting tank to be collected, so that the rainwater is prevented from directly sliding down to the air film foundation, and the air film foundation is ensured not to be corroded by the rainwater.
