Between manhole connecting structure and Drain pipe

摘要

When connecting a water pipe to the connecting passages of the subject innovation manhole, hayeoseo configure the connection gap to give to the sealing as the inorganic filler that solidifies be filled in the expandable tube and fill the space therein, significantly the working conditions for connecting the drain pipe to the connection passage of the manhole improved by giving the same time that can enhance workability, the drain chambers to the connecting passages of the manhole and firmly connected to provide a manhole water pipe connecting structure of giving significantly improved by the construction quality.; Water pipe connecting structure of the subject innovation manholes in that for connecting the drain pipe 20 through the connection passage 11 of the manhole 10 to be buried in the ground, the drain pipe is fitted in the connection passage (11) of the manhole (10) ( 20) end portion 21, the outer peripheral surface circumference is filled in the inner space 31 so that the volume expansion is formed to install the expandable tube (30) having an inlet (32) in fluid communication with the fill space, and wherein the expandable tube ( thereby through the inlet 32 ​​of 30) filled filling the space (a paste state of the inorganic fill material 40 within 31), the end portion 21 of the connection passage 11 and the drain line 20 of the manhole 10 be the expandable tube 30, the inorganic filler 40 is filled in the expanded state is tightly adhered filling space 31 is solidified, so that one will be effectively sealed by the connecting gap (a).
