Description
Technical Field
The utility model relates to a flood control device field, in particular to access & exit gasbag formula watertight fittings.
Background
Natural disasters frequently occur in China, particularly in high mountain canyon regions in the southwest, side slopes after earthquake, serious vegetation damage, loose collapsed objects on the surface of the slope surface with poor stability, and long-term exposure of mountains, so wind sand and small rolling stones are easily caused; in heavy rain, landslide or debris flow easily occurs to block a river channel to form a barrier lake, so that a factory building is flooded with water, more serious loss is caused, and the repair difficulty is huge. The specific situation is as follows: (1) flooding in super design standard: the upstream of the watershed has strong rainfall or other special reasons, so that the flood exceeds the designed (checked) flood level, and accidents such as dam overflow (dam break) of a hydropower station, plant water inflow, hydraulic construction damage, power failure and tripping of a total station and the like are caused; or when the water level of the downstream rises, water enters a factory communication hole (door) from the factory building, and enters the factory building from a tailrace communication hole.
(2) Super design standard rainfall: strong rainfall is continuously concentrated in a short period of the factory area, and when the rainfall exceeds the design standard, a large amount of accumulated water in the factory area can be caused to flow into the factory building, and the whole factory drainage system can not meet the drainage requirement; or the rainwater is poured into the factory from the positions of a roof drainage ditch, a door window, a cable trench, a drainage ditch and the like or is poured backwards into the factory. (3) Landslide, debris flow: landslide induced by the flood discharge atomization area, landslide and debris flow near the plant area possibly exceed drainage capacity, damage the blocking structure, cause damage to buildings, traffic interruption and failure of the drainage structure in the plant area, and possibly directly damage the plant structure or cause flooding of the plant. In the '8.13' rainstorm period in 2010, debris flow disasters are generally developed in all large and small branch ditches of the Minjiang river basin. Large debris flows are developed in the burning ditches and the heaven ditch at the downstream of the Xiuwan hydropower station, the flushing amount of ditch openings reaches more than 60 ten thousand cubic meters, the burning ditches and the heaven ditch block the Minjiang main river channel to form a choked lake, and the tail water level of the raised factory site area reaches 893.4 meters, which is about 4 meters higher than the water level of a dammed lake in the case of 5.12 Wenchuan extra earthquake. River water flows back to the factory building through a tail water hole of the Xixiu bay hydropower station and a factory-entering traffic hole of the first-level hydropower station of the Fishery brook, so that the flooding loss is caused.
the hydropower station factory building (particularly the underground factory building) is a region where accumulated water is easy to occur due to low terrain, in recent years, in a flood season or occasional heavy rain, rainwater cannot be timely discharged from the hydropower station factory building due to overload of a drainage system, electrical equipment and facilities are submerged, and a major non-stop accident of a unit is caused, and by referring to 'reinforced construction project drainage waterlogging prevention capacity planning guidance' which is given by a planning bureau of a related city in 2013, the height of an entrance of an underground parking lot is clearly required, and the entrance of the underground parking lot is higher than a sidewalk of a peripheral municipal road by more than 30-50 cm; the height of the water baffle can be set according to the experience in various places, but should not be higher than 100 cm.
Therefore, it is necessary to provide a flood barrier device capable of automatically closing the traffic hole of the hydropower station. The water-retaining and flood-preventing device has the functions of preventing rainwater from being poured into a hydropower station workshop and achieving a good flood-preventing and water-retaining effect; the input of flood prevention manpower is saved when the flood season comes, when the water level rises, the water baffle can be installed within five minutes through the water level sensing device arranged at the traffic entrance and exit of the hydropower station plant, and people do not need to be sent to carry the sandbags; the sand bag has the advantages that the cost of the sand bag is saved, the sand bag can achieve the effect of preventing water invasion without being matched with the sand bag, the sand bag does not need to be replaced with a new sand bag every year in flood season, and the space for storing the sand bag is also saved.
