Residential neighborhood
7 floors and eaves height of 20 meters above the residence, we call high-rise residential. High-rise housing is generally equipped with elevators as a vertical transportation, for which the state also clearly stipulates: 12 floors and more than 12 floors of high-rise housing, each unit set up no less than two elevators. In the choice of floor, some professionals remind that we should avoid choosing the so-called ash layer, the so-called ash layer can be simply thought of as a high-rise building in the 30 meters or so position is exactly the air in the concentration of the most concentrated range of floating dirt. Therefore, there is a saying in the industry that 8-13 floors of the house is the best to buy.
Precautions for high-rise residents
Electromagnetic radiation When it comes to electromagnetic radiation, not many people can understand. Reinforced concrete structures force waves from electrical equipment to circulate along the house, with a significant portion going up to the top floor. As a result, residents of high-rise buildings often suffer from headaches or bad moods. In addition, as the number of high-rise buildings continues to grow, so does the number of secondary water supply facilities built to meet their water needs. The term "secondary water supply" is short for secondary water supply for drinking water, which refers to the indirect supply of drinking water to users through secondary water supply facilities. Secondary water supply facilities include high, medium, and low level reservoirs and attached piping, valves, pumping units, frequency converters, pneumatic tanks, and other facilities that are set up to protect drinking water. As the secondary water supply is "water plant - pipe network - secondary water supply facilities - users" in the process of relatively open links, than the municipal network water is more susceptible to contamination, pools (tanks), if not regularly cleaned and disinfected or mismanaged, it is very easy to cause secondary contamination of water quality. According to reports, some neighborhood roof cisterns and water tanks have been unmanaged for years, the sanitary condition is worrying, some cisterns and water tanks are full of moss, and some pools have not been covered for a long time, and a lot of insects have fallen into the pools, and the cost of maintenance is also a small amount of expenditure. The owners have to pay for the normal operation and maintenance of the equipment.
