The temperature of Heilongjiang in winter is lower, and the guarantee of winter heat supply quality is an important work. In the face of many factors such as pipe network ageing, construction quality and the like, pipeline leakage frequently happens, rush repair is more frequent, according to actual conditions, the temperature is lower in winter, after leakage points are treated, waterproof, heat preservation and other items are not effectively treated, after backfilling, surface water can infiltrate each other along the heat preservation damage of the pipeline, so that the pipeline is corroded in a large area, the service life of the pipe network is shortened seriously in a long time, a large amount of heat energy and water resources are wasted, and the heat supply cost is increased. The common heat preservation mouth filling method has two modes, namely a sleeve mouth filling mode and an electric heating mouth melting mode. The oversleeve joint filling mode is that a heat shrinkage belt is sleeved into a heat supply main pipe, the heat shrinkage belt and an original heat insulation shell are bonded together through fire baking shrinkage, the aim of water resistance is achieved, then holes are formed, polyurethane materials are uniformly stirred and poured, and Kong Pan is glued and sealed after foaming is finished; the electric heating welding method is to select proper electric heating sleeve, to use special electric heating welding machine to heat the electric heating wire, to heat for 20-40 min (to confirm the hot melting time), to bond the sleeve and the main pipe, to open one end of sleeve pipe to form a 30mm diameter injection hole, to open another end to form a vent hole, to stir polyurethane material, to pour into or pour into with casting machine, to be sealed with special plug. The sleeve joint opening mode has the advantages that the line pipe is disconnected and sleeved for construction, and the condition that the heat preservation part of the main pipe is damaged due to rush repair in an outdoor heat supply state in winter cannot be met; and the electric welding joint coating mode can not meet the construction conditions outdoors in winter in Heilongjiang province.
