Rainwater collecting structure based on macromolecule protection drainage special-shaped pieces

The invention relates to the field of underground water collection, and discloses a rainwater collection structure based on a polymer protection drainage special-shaped sheet, the rainwater collection structure comprises a siphon water collection tank, the top of the siphon water collection tank is uniformly provided with a plurality of groups of air holes, and one end of the top of the siphon water collection tank is provided with an air-permeable observation pipe; through cooperation of the siphon water collecting tank, the first reinforcing strip plate and the through groove, in the using process of the device, the bearing capacity of the interior of the siphon water collecting tank can be improved, so that after the siphon water collecting tank is buried in the ground, the situation that the siphon water collecting tank deforms due to the pressure of soil can be avoided, in the siphon process, the siphon water collecting tank is not affected by suction force, and the service life of the siphon water colle
