A water discharge pipe and drain head assembly structure that, by means of a matched drain head inner diameter bore, seal ring shape, and clamp ring, enables the utilization of a simple stomp operated, additionally fabricated, foot-driven component which is sleeved into the inner diameter bore of the drain head to shove down the clamp ring a predetermined distance and thereby compress and deform the seal ring such that a tightly sealed contact is established against a water discharge pipe inserted through them. The arrangement effectively affords optimal watertight anti-seepage efficacy between the water discharge pipe and the drain head, fully solving the numerous problems and shortcomings of the conventional threaded-type mounting ring.
