With the development of the city, in order to meet people's basic living needs, the city has implemented a form of collective heating. As for the laying methods of heating pipelines, they usually include overhead, trenches and direct burying techniques. Due to the diversity of heating pipeline design methods, the compensation contradiction of the urban pipeline network is prominent, which seriously affects the purpose of collective heating. To change this prominent contradiction, the city should combine the construction characteristics of heating pipelines in the selection of heating pipe network compensation methods, construct a design plan for centralized heating pipe network, solve the problem of heat compensation in time, and provide support for the development of the city. .
