Why did the roof of the residential area leak rain overnight, and the whole building became an ice waterfall?

According to media reports, the top floor of a residential area in Shenyang, Liaoning Province leaked water in June 65438+1October 10. As a result, after a night, the whole building seemed to be covered by a white icicle waterfall, and some netizens lamented that it was quite "spectacular". The first floor was the hardest hit, and the glass outside the balcony was covered with thick ice, which looked like a waterfall from a distance.

According to the report, the top floor seems to be uninhabited for a long time, so it was not handled in time after the water leaked. Witnesses recalled that it was probably leaked from two o'clock in the afternoon the day before until today's 12, and finally the leak was stopped after the fire arrived. Some lower-class residents said that it seems that it has not affected their lives yet, but it looks scary. At the same time, due to the good weather these two days, icicles fall, which may cause danger to pedestrians.

A residential area in Dandong15m ice valve hanging on the roof?

14 On February 28th, residents of Building 14, Dongfang Fengjing Community, Zhen 'an District, Dandong sent a thank-you letter to Dandong Fire Rescue Detachment. The reason should start with an "ice-breaking operation" a few days ago.

The residential building has 7 floors, and the ice valve extends downward from the top of the seventh floor along the external wall of the building, with a length of about 15 meter and a diameter of about half a meter, so residents can detour when passing by. "There are many people walking, and the ice valve will fall down at any time. What can I do if I hit someone? " Resident Mr. Zhang said that this ice slot was caused by the leakage of solar water heaters on the roofs of individual households, and even the air conditioning plug-ins of neighbors on the third and fourth floors formed a "small iceberg", which made people feel scared.

The temperature plummeted and the ice was serious, and the residential property could not be handled by itself. ? "I haven't seen such a big icicle for two years. Hanging on the roof looks like a waterfall. If you hit someone, the consequences will be unimaginable. " Ms. Zou, a resident of the building, said. In desperation, residents dialed 1 19, and a five-person car from the special service station of Linjiang Back Street of Dandong Fire Rescue Detachment immediately rushed to the scene. After observing and analyzing the freezing state upstairs and downstairs, the field commander asked a fireman to set up a warning tape.

After obtaining the consent of the residents on the top floor, firefighters decided to adopt a top-down and layered demolition method to clean up. In order to prevent the smashed ice from damaging the windows and air conditioning plug-ins of the downstairs residents, firefighters hung in the air with ropes and threw huge ice cubes away from the building as much as possible. Nearly an hour later, from the seventh floor to the second floor, the ice valve was thoroughly cleaned, and the applause and applause of the onlookers downstairs rang.
