A pipe connector for a manhole and a construction method thereof are provided to assemble a pipe easily, to adjust the angle of the pipe conveniently, and to improve sealing efficiency and durability by installing the pipe connector integrally with the manhole in pouring concrete. Plural assembling holes(13) are formed in a pipe connector(10), and a reinforcing projection(12) is formed in the outer periphery of the pipe connector. A cover(30) is combined with the pipe connector to seal by pressing an outer sealing member(26) and an inner sealing member(25) mounted in a hollow. An inner projection(15) and an outer projection(14) are protruded in the outer periphery of the pipe connector by a recess(16) for sealing. Watertight rings are formed around the inner projection and the outer projection, and expanded to seal pores when contacting with water. |
