一、正确計算地下压力鋼管的重要性火力发电厂的工业供水管道,尽管現在已較普遍地采用鋼筋混凝土管来代替鋼管,但在厂区和主厂房内、特别是容量較大的电厂,往往还需采用鋼管。这是因为鋼筋混凝土管,其保証絕对不渗漏的可能性还远不如鋼管。如果管道发生渗漏,将会影响厂房基础不均匀下沉。在容量較大的电厂内,这部分鋼管的长 First, the correct calculation of the importance of underground pressure steel pipe Thermal power plant industrial water supply pipe, although now more commonly used reinforced concrete pipe instead of steel pipe, but in the factory and the main plant, especially large capacity power plants, often Need to use steel pipe. This is because the reinforced concrete pipe, which guarantees the possibility of absolutely no leakage is far less than steel. If the pipe leakage occurs, it will affect the plant foundation uneven subsidence. In the larger capacity of the power plant, this part of the long steel pipe
