Numerical Calculation of Insulating Layer Thickness of Rural Water Supply Pipe in Permafrost Regions

Abstract

In permafrost regions of China, the rural water treatment devices have problem in safe and reliable operation, especially in winter. The phenomenon of rural water supply pipes frost heave often happens and does great harm to water supply system’s reliable operation .Thus, the research of anti-freezing technologies are necessary for regular production and lives of peasants .In order to solve the problem, this article introduce the anti-freezing technology of straight-buried pipe with insulating layer. Through theoretical analysis and calculation, the insulating layer thickness can be determined.
