After setting, start the drive mechanism 5 and the hot air welding gun 7 to move up or down to start welding. After welding is completed, loosen the top fixing frame 4 and push the construction device away.

[0055] Specifically, based on the determined hot air welding temperature and the traveling speed of the welding system, relevant parameters are set in the temperature control display and switch controller. After the parameters are set, the variable frequency motor drives the automatic welding system to begin trial welding. Once the quality of the vertical joint construction of the waterproof membrane in the trial welding is verified to meet the relevant requirements, the formal welding of the vertical joints of the waterproof membrane can begin.

[0056] The construction method in this embodiment solves the problem of welding and connecting vertical joints of the waterproof membrane on the outside of the basement, ensuring the forming quality of the waterproof membrane joint welding construction, improving the construction speed, and ensuring construction safety.
