The invention discloses a construction method of prefabricating and pre-embedding a multi-row sleeve pipe assembly. The construction method includes the steps that 1, the multi-row sleeve pipe assembly is prefabricated, wherein a plurality of sleeve pipes of the multi-row sleeve pipe assembly are located and tightly locked, and then the sleeve pipes of the multi-row sleeve pipe assembly are connected; 2, the multi-row sleeve pipe assembly is transported; 3, the multi-row sleeve pipe assembly is preliminarily embedded. According to the construction method of prefabricating and pre-embedding themulti-row sleeve pipe assembly, by adopting a multi-row sleeve pipe assembly prefabrication mold, firstly, the sleeve pipes which are arranged in rows are prefabricated into the multi-row sleeve pipeassembly, after the multi-row sleeve pipe assembly is transported to a construction field, a multi-row sleeve pipe assembly pre-embedding tool is adopted to preliminarily embed the multi-row sleeve pipe assembly, the accuracy of the intervals among the sleeve pipes can be ensured, the consistency of the mounting heights of the sleeve pipes can be ensured, the perpendicularity between the sleeve pipes and a template can be ensured, and therefore the problems of accurate location between pipelines and buildings, among pipelines and between pipeline layers and layer vertical directions are solved.
