PURPOSE: A unification coupling structure of sewer pipes is provided to prevent environmental pollution and leakage, and to heighten economical efficiency. CONSTITUTION: The unification coupling structure of sewer pipes contains: a watertight socket(20) composed of an inlet(21) to place binders(30) to a connection pipe where a sewer pipe is interposed; sewer pipes(10,11) fitted to face each other on both sides of the watertight socket(20); a closed rubber ring(25) closing up an interval between the watertight socket(20) and the sewer pipes(10,11); and binders(30) filled in an interval among the watertight socket(20), the sewer pipes(10,11) and the rubber ring(25) through the inlet(21). |
