The upper end of the vertical plate (A) on the bottom module (6), the upper end of the vertical plate (A) on the lower module, and the upper end of the vertical plate (A) on the corner module (9) are all provided with an opening groove (A-1) with an upward opening. The opening groove (A-1) divides the upper end of the vertical plate (A) into two legs (A-2) on both sides. The opening grooves (A-1) on the two adjacent vertical plates (A) are joined together to form a water passage hole. The vertical plates (A) are provided with notches (A-3) on both sides of the vertical edge. The notches (A-3) on the two vertical plates (A) on the upper half of the prefabricated rainwater collection tank are joined together to form an opening groove (A-4) with the opening facing downward. The notches (A-3) on the two vertical plates (A) on the lower half of the prefabricated rainwater collection tank are joined together to form an opening groove (A-4) with the opening facing upward. The two opening grooves (A-4) are joined together to form a water passage hole. The vertical plate (A) is provided with several weight-reducing holes (A-5) at the end away from the support leg (A-2).

14.
