ABSTRACT:
A plastic swimming pool with an enhanced structure comprises a pool wall, a connecting sheet, a base sheet and an inflatable ring, said pool wall is connected with the base sheet via the connecting sheet, the inflatable ring is mounted on a top of the pool wall, said pool wall is formed by connecting a plurality of sidewalls at both sides of them with each other into a loop, the connecting sheet is bonded to the inner side of the lower portion of the pool wall, the connecting sheet is formed by connecting a plurality of material sheets at both sides of them with each other into a loop as well, the welding seams between the sidewalls and the welding seams between the material sheets of the connecting sheet are staggered; the width of an interface for welding the sidewalls and the connecting sheet is more than 80 mm and reinforcing seals are provided in the interface where the sidewalls and the connecting sheet are bonded, and a bottom ring of the connecting sheet is connected directly with the base sheet. The advantage of the present invention is that the reinforcing sheet is integrated with the connecting sheet, meanwhile, the material sheets having reinforcing function become a closed loop around the pool wall, hence, the pool wall is reinforced, the welding seams are protected and possibility of water-leaking is decreased.
