Description

Flood gate for open section of subway tunnel and control method thereof Technical Field The invention relates to the technical field of urban rail transit engineering, in particular to a flood gate for an open section of a subway tunnel and a control method thereof. Background The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. The subway is usually arranged below the ground, is a relatively closed space, and has the characteristics of concealment, blockage, high density of personnel and equipment and the like, and is difficult to evacuate and rescue. The subway is communicated with the outside through the wind shaft, the entrance and the exit, the line hole and the like. Therefore, when a flood disaster occurs in a city, flood water preferentially enters the interior of the subway and rapidly spreads over the whole communication area of the subway. In order to prevent rainwater from flowing backward, the subway entrance/exit line, namely the transition part from underground to ground, is generally in the form of a U-shaped groove connected with a tunnel portal, the track bed and the rail are laid on one U-shaped groove from the tunnel portal until the rail is completely exposed out of the ground, the two sides of the U-shaped groove are reinforced concrete flood-proof walls, and the flood-proof walls are always 1 meter higher than the ground outside no matter how the gradient of the lines changes. At present, a mode of installing a flood gate at a U-shaped opening is adopted to further prevent flood from flowing backward into a subway exit/entrance (section) line, but the existing flood gate is not tightly sealed with a track, so that the waterproof effect of the flood gate is limited, and flood can still enter the subway exit/entrance (section) line through a gap between the flood gate and the track.
