[0002] In the construction, the floor heating pipeline laying is the important link of the heating and ventilation engineering. The traditional laying mode usually directly piles the pipeline on the ground, and the construction personnel need to arrange and pull the pipeline. However, this method has many disadvantages. On the one hand, the pipeline is placed in disorder on the ground, which can easily lead to the winding and damage of the pipeline, and increase the construction difficulty. The construction personnel need to frequently arrange the pipeline in the laying process, consume a large amount of time and manpower, and seriously affect the construction efficiency. The laying device does not have the folding function, and is inconvenient to fold and carry, so the above problems greatly affect the construction convenience of the personnel. UTILITY MODEL CONTENTS
