The utility model discloses a multi -functional spacing formula FRP pipe says and connects mounting structure, including outside pipeline and FRP pipe way, between saying, two adjacent FRP pipe meet through socket joint, the outer wall that FRP pipe said do not is provided with a spacing block group near both ends position punishment about it, spacing block group is by the edge FRP pipe says that three piece at least multi -functional stoppers of outer wall circumferencial direction evenly distributed constitute, multi -functional stopper is close to FRP pipe say the terminal surface of tip be with the vertical face of socket joint complex is worked as FRP pipe says and inserts in the socket joint during up to standard position, this vertical face just with the cooperation of socket joint tip is pasted mutually. The utility model discloses can guarantee that socket joint and FRP pipe say that the butt joint is at fixed position for construction speed is faster, and socket joint and FRP pipe say that the butt joint is more perfect, gos back the multi -functional stopper of accessible and blocks socket joint, makes socket joint can not control and removes.
