Description

Full-automatic flood-proof protective airtight door
Technical Field
The invention relates to the field of tunnel equipment, in particular to a full-automatic flood-proof protective airtight door.
Background
When a highway tunnel passes through a large surface water body, flood gates can be arranged at proper positions of two end opening parts of the tunnel to finish the blocking of the tunnel opening parts in order to prevent water bodies from entering the tunnel due to sudden accidents such as tunnel leakage, local collapse and the like and from the flood irrigation of the tunnel opening parts to towns on two sides. Meanwhile, the underpass tunnel is lower in topography, when extreme rainfall occurs, rainwater is easy to pour into the tunnel through the openings at the two sides, so that the safety of personnel in the tunnel is endangered, and in the situation, the flood gate can be closed to prevent flood from entering the tunnel, and the personnel in the tunnel can be ensured to withdraw from the tunnel through the tunnel escape passage.
Compared with other types of protective airtight doors or flood doors, the highway tunnel flood door has the following characteristics: the aperture size is large, the single-side tunnel is generally more than three lanes, and the aperture width is generally more than 12 m. The road surface generally has two slopes, namely longitudinal and transverse, which brings new problems for opening and sealing the door leaf. The arrangement position of the flood gate of the highway tunnel needs to ensure barrier-free traffic, and cannot adopt the arrangement mode with a threshold. The arrangement place of the flood gate is generally a single-layer building structure, and is subject to excavation conditions and cost, and the reserved space of the flood gate is small.
The existing highway tunnel flood-proof door mostly adopts a landing structure, and a groove is generally arranged at the bottom of the flood-proof door, so that the flood-proof door needs to drop the whole door leaf into the groove when being closed, and locking and sealing of the door leaf are completed. When the door leaf is opened, the door leaf is required to be integrally lifted out of the groove, and then the door is vertically rotated to overcome the influence of the road gradient on the opening of the door leaf. The bottom of the flood gate is provided with a groove, a trench cover plate is required to be used for plugging at ordinary times, and hidden dangers that falling affects the driving safety in a tunnel exist. And the operation process is complex, and the full-automatic operation of the equipment cannot be realized.
