当水电站的水压钢管为露天布置时,由于基础的不均匀沉陷、地震、钢管的锈蚀或磨损(木制管的腐烂)、机组的不正常运行而引起的振动以及空放阀失灵等原因,常常遭致爆破损坏。水压钢管爆破后,大量出水将淹没电厂和附近的农村,从而造成严重的事 When the hydraulic steel pipe of the hydropower station is arranged in the open air, due to uneven foundation settlement, earthquakes, corrosion or abrasion of the steel pipe (rotting of the wooden pipe), vibration caused by the abnormal operation of the generating unit and failure of the empty discharge valve, Often damaged by blasting. After the water pressure pipe explosion, a large number of water will submerge the power plant and the nearby rural areas, causing serious problems
