Or a short eyebolt 19 and a screw shaft 21 screwed together by a long nut 20. In addition, the pressing body 34 that holds the heel body 3 from the other side in cooperation with the support body 10 is formed by forming the support shaft portion 30 that guides and supports the inflow pipe 9 directly on the pressing body 23. A hollow cylindrical guide seat 31 having a stepped portion in which a support shaft portion 30 for guiding and supporting the inflow pipe 9 is formed on a small-diameter round shaft portion 25 of 23 is provided by being detachably fitted and attached.

Next, the operation of the pipe fitting jig B of the present invention will be described below based on the drawings.
As shown in FIG. 1, the pipe fitting jig B of the present invention composed of each of the above-described constituent members has a support body 10 housed inside the main body 3 of the drainage basin 1 having the above specifications at the site of the wastewater treatment work. The ring portion 37 of the eyebolt 19 inserted from the outside into the inlet 4 of the pipe connection portion 5 is engaged with the hook 15 projecting below the support body 11 while being visually observed from the upper part of the heel body 3.
When the ring portion 37 is engaged with the hook 15, the screw shaft 21 is pulled in until the curved surface of the support body 11 comes into contact with the inner peripheral surface of the heel body 3, and in this state, the inflow pipe 9 is connected to the support shaft portion 30 on the screw shaft 21. The pressing body 34 that is externally guided and supported is inserted through the insertion hole 22, the pressing adjusting body 28 is sequentially inserted from the rear, and further, the pressing nut 29 is screwed behind the pressing nut 29. By rotating with the tool (not shown), the pressing body 34 pushes the inflow pipe 9 into the inflow port 4 via the pressing adjusting body 28.

An O-ring 38 is fitted on the inner periphery of the inlet 4 of the pipe connection part 5 in order to maintain water-tightness before and after that, and a considerably large frictional resistance is applied when the inflow pipe 9 is pushed. It may be difficult to determine whether the load is due to this frictional resistance or due to the twisting posture of the inflow pipe 9, but at this time, the pressure is pressed via the vertical movement (very slight swing) of the screw shaft 21. When the pressing posture of the inflow pipe 9 guided and supported by the body 34 is finely adjusted, the pressing body 34 moves smoothly due to the compression reaction force of the coil spring 27, so that it can be determined that the state is a normal pressing posture. In this state, if the screw nut 21 is held and the pressing nut 29 is rotated, the inflow pipe 9 and the O-ring 38 can be watertight without being damaged, and the inflow pipe 9 can be securely and securely fitted to the inflow port 4. Things .
As described above, according to the pipe fitting jig B of the present invention, the inflow pipe 9 can be fitted into the inflow port 4 in a labor-saving manner with a slight effort due to the rotation of the pressing nut 29, and the coil spring 27 of the pressing adjusting body 28. The pressure posture of the inflow pipe 9 is finely adjusted by the action of the compression reaction force, and a safe and highly accurate fitting is achieved.

  The pipe fitting jig B of the present invention achieves labor saving of the fitting work of the inflow pipe with respect to the inlet of the pipe connection part of the drainage basin in the wastewater treatment work, and is a safe and highly accurate fitting. It can be widely used in the wastewater treatment industry because it contributes to the improvement of reliability by accomplishing the work.
