Precautions for laying floor heating coils; the ambient temperature of construction should not be lower than 5°C; when constructing in an environment lower than 0°C, heating measures should be taken on site; during the construction of ground radiant heating projects, it is strictly forbidden for personnel to step on the floor heating pipes; the construction process During the heating process, paint, asphalt or other chemical solvents should be prevented from contacting and polluting the surface of the floor heating pipe; the heating coil is laid on the steel mesh, and the length of the pipe is determined according to the length of each circuit. The buried part of the coils laid under the ground should not have joints; the floor heating pipes should be laid according to the pipe spacing and direction calibrated in the design drawings, the floor heating pipes should be kept straight, and the floor heating pipes in the same passage should be kept horizontal to ensure that the flatness of the pipe top is ±5mm. The installation error of the pipe spacing should not be greater than 10mm. Before the floor heating pipe is laid, the selection, diameter and wall thickness of the floor heating pipe should be checked against the construction drawings, and the appearance quality of the floor heating pipe should be checked, and there should be no debris inside the pipe.
