PURPOSE: A position shifting installation structure of an inlet pipe in a manhole equipped with two kinds of inlet pipes is provided to facilitate to construct a manhole by shifting the mutual positions of domestic sewage and human waste pipes. CONSTITUTION: A position shifting installation structure of an inlet pipe in a manhole equipped with two kinds of inlet pipes comprises a pair of inlet pipes(1a,1b), L-shaped guide pipe fixing grooves(10,10a), water tubs(11,11a), a cover plate latching protrusion(13), a protruding piece(20a), and a latching groove(21a). A pair of inlet pipes is extended to the inner side of the lower main body(1) of a manhole. An L-shaped guide pipe fixing groove is formed in the extended end of the inlet pipe. A water tub is formed by partitioning the manhole bottom surface in the outlet of the inlet pipe through a partition(12). The cover plate latching protrusion is formed on the front end wall of the water tub. The protruding piece is formed in one front end of an L-shaped guide pipe(20) for selectively assembling the L-shaped guide pipe fixing groove. The latching groove is formed at both sides of a cover plate in order to be assembled to the cover plate latching protrusion. |
