The invention relates to the technical field of heat preservation pipelines, in particular to a prefabricated directly-buried heat preservation pipe with an energy-saving monitoring function, which comprises an inner pipe, an outer pipe, a heat preservation layer, a temperature control switch, a current signal generator, a current signal detector, a wireless signal transmitter and a master controller, the invention further relates to a monitoring method of the prefabricated directly-buried thermal insulation pipe with the energy-saving monitoring function. A plurality of temperature control switches capable of detecting the peripheral temperature of the heat preservation layer are evenly arranged on the periphery of the outer pipe, so that when the inner pipe leaks, and the peripheral temperature of the heat preservation layer gradually rises, the positive wire and the negative wire can be conducted, and therefore a current signal detector can detect a current signal sent by a current signal generator; theref
