The utility model relates to the technical field of thermal contraction belts, in particular to a buried steel pipeline thermal contraction belt which comprises a winding wheel, sliding grooves are formed in the two sides of the interior of the winding wheel, springs are installed on the lower portions of the interiors of the sliding grooves, the top ends of the springs are connected with limiting rods, and bearings are installed in the middles of the two sides of the outer surface of the winding wheel. According to the utility model, the defects in the prior art are overcome, and the sliding chute, the spring and the limiting rod are arranged, so that when the heat-shrinkable tape is used, the limiting rod is positioned right above the heat-shrinkable tape, and the spring is in a stretching state, so that the heat-shrinkable tape can be guided and limited to a certain extent through the limiting rod when the heat-shrinkable tape is stretched from the winding wheel; the heat shrinkage belt is flattened throug
