Construction method of fixed embedded type waterstop and structure of fixed embedded type waterstop

The invention discloses a construction method of a fixed embedded type waterstop and a structure of the fixed embedded type waterstop. The construction method comprises the following steps: manufacturing a plurality of positioning structures, wherein each of the positioning structures comprises two symmetrical positioning rebars formed through bending rebars; the positioning rebars comprise two equal-height right trapezoids; the bevel edges of the two equal-height right trapezoids are parallel; and a limiting hole for mounting a waterstop is formed between the bevel edges of the two equal-height right trapezoids; making positioning lines on the two sides of a telescopic seam to determine the mounting positions of the positioning rebars and the waterstop; mounting the positioning structuresin the length direction of the telescopic seam according to the positioning lines, and enabling the positioning rebars to be connected with main body rebars on the two sides of the telescopic seam; and mounting the waterstop
