Description

Flood gate structure for underground cavern

Technical Field

The utility model relates to flood control equipment, in particular to a flood control gate structure for an underground cavern.

Background

The flood control type of underground garages of residential districts built in each province and city in China at present is basically that a transverse open drainage ditch is built at the entrance and the exit of the garage, and the open drainage ditch is used for guiding and draining ground rainwater entering the garage. The section of the open channel is rectangular, the size H is 500mm for 400-. The rain collecting and draining open drain is usually connected with the unorganized drainage of the ground of a district road, the open drain is easy to block and lose the design function, and the ground runoff flood formed by the extremely heavy rainstorm cannot be effectively resisted.

In order to enhance the flood fighting and disaster prevention capability of the garage, each community usually adopts a targeted enhancement measure that a corresponding number of sandbags are put in place in the last 5 months before the coming flood season, and the sandbags are stacked beside the side walls of the entrance and exit for emergency use of flood fighting and emergency rescue. The sand storage bag is a form used by a base unit to cope with the upper level inspection flood control and emergency rescue.

The flood control plan of the sand storage bag is widely applied to garage entrances and exits all over the country. The scheme not only needs the basic unit to check and update the rotten sandbags every year, but also has little disaster prevention effect in the time period of encountering abnormal strong rainfall, so that the underground garage is difficult to escape the accident of disaster.

The ground surface ground of the underground traffic entrance and exit established in each province and city of China is generally 500-1000mm higher than the ground of the adjacent road, and the ground surface relative height difference can completely resist surface runoff flood caused by strong rainfall within a certain period of time. Therefore, the underground traffic entrance and exit are not provided with targeted reinforced flood control measures in operation.

However, for the flood impact of surface runoff caused by extreme strong rainfall generated in extreme weather, once risks which are not considered in the design occur due to the grading of buildings, the existing flood control type is difficult to deal with. The flood control device which is convenient, convenient to use and manufacture does not exist for underground caverns such as garage entrances and exits or unidirectional exits and entrances.
