With the lowering of the lifting mechanism, the heating roller 10 connected at the bottom of the second connecting plate 15 gradually contacts the waterproof roll on the ground, and the adjusting screw 17 is continuously rotated, the heating roller 10 generates pressure on the waterproof roll, and at the same time, the two walking wheels at the rear side are away from the ground, at this time, only the front two walking wheels 2 and the heating roller 10 support the entire device.

[0040] The power is turned on, the current is transmitted to the electric heating element in the heating roller 10, the surface of the heating roller 10 is heated to the preset working temperature. The two walking wheels 2 at the front side guide, the heating roller 10 acts as the main bearing wheel and the driving point and rolls forward, in the slow moving process, the waterproof roll 9 rotates smoothly in the four-point roller support, and the waterproof roll is released. The roll softened by heating is rolled on the ground by the heating roller, realizing preliminary bonding and flattening.

[0041] After the paving is completed, the heating roller power is turned off. The adjusting screw 17 of the lifting mechanism is reversely rotated, and the heating roller 10 is lifted away from the ground. At this time, the rear walking wheels 2 of the device contact the ground again, and the four-wheel support state is restored.
