INFLOW PIPE CONNECTING STRUCTURE TO VERTICAL PIPE

摘要

PROBLEM TO BE SOLVED: To provide an inflow pipe connecting structure to a vertical pipe, capable of simply performing restoration when a pipe is blocked up with solid matter and performing connecting work for the inflow pipe to the vertical pipe with good workability. SOLUTION: In this inflow pipe connecting structure to the vertical pipe, while the end of the inflow pipe 60 projected into a manhole 50 is passed through an opening 22 and a vertical pipe connecting part 23 is connected to a socket 111 at the upper end of the vertical pipe body 11 in a socket-plug method, an inflow pit 20 is fixed to the wall inner surface of the manhole 50 by a fitting. A water cut-off plate 30 is fixed to the peripheral wall of the opening 22 of the inflow pit 20 with the end of the inflow pipe 60 passed through the penetrating hole 321 of the inflow pipe and with the gap between the surfaces at the end of the inflow pipe 60 sealed with a rubber ring 32.
