The vertical tube portion 30 has a substantially cylindrical shape, and a wall extends from a position slightly shifted outward from the upper and lower ends thereof to form a receiving port portion 31 having a diameter larger than the inner diameter of the vertical tube portion 30. The branch pipe part 33 protrudes from the side wall of the vertical pipe part 30 in a direction orthogonal to the axial direction of the vertical pipe part 30. An L-shaped corner portion 32 is formed at the boundary between the branch pipe portion 33 and the downstream receiving port 31 pipe.

  The cleaning port 2 is a cylinder having substantially the same diameter as the inner diameter of the branch pipe portion 33, and a female screw 20 is formed on the inner peripheral surface of the end portion.

  The wire rod guide mechanism 1 includes a cap portion 10, a wire rod guide tube portion 11, a protruding portion 12, a male screw 13, a rib 14, a rib groove 15, and a female screw 16.

  The cap portion 10 has a disk shape larger than the diameter of the cleaning port 2, and from the outer peripheral edge of the disk to the back surface (referred to as a surface facing the cleaning port 2 when attached to the cleaning port 2). .) Is bent to the side to form a rib 14. An annular rib is provided on the back surface of the cap portion 10, and a rib groove 15 is formed between the outer periphery of the annular rib and the inner periphery of the rib 14. The outer diameter of the annular rib is substantially the same as the diameter of the cleaning port 2, and a male screw 13 is formed on the surface facing the rib 14.

Projecting from the front surface of the portion 10 (referring to the back surface of the back surface, hereinafter the same), the other end opening faces the outside. Hereinafter, a portion protruding from the cap portion 10 is referred to as a protruding portion 12, and the other end opening is referred to as an opening of the protruding portion 12.

  The protruding portion 12 is curved toward the outer peripheral edge of the cap portion 10. The opening of the protrusion 12 is smaller than the diameter of the cleaning port 2, and is provided at a position eccentric from the center of the cap 10. The protrusion 12 has a female screw 16 formed on the inner peripheral surface near the opening.

Thus, the standing pipe structure is constituted by a plurality of members.
Here, a method for constructing a standing pipe structure using a plurality of members will be described. As shown in FIGS. 1 and 2, when the pipe joint 3 is incorporated in the middle of the standing pipe line, the pipe receiving part 31 is opened up and down and the branch pipe part 33 is installed in the horizontal direction.

  In the pipe joint 3, the end of the upstream stand pipe 40 is fitted into the upper receiving portion 31, and the end of the downstream stand pipe 41 is fitted into the lower receiving portion 31, respectively. The abutment edge 40 abuts on the upper end or the lower end of the standpipe portion 30, thereby fixing the standpipe 40 or the standpipe 41 in a fixed position.

  Further, the pipe joint 3 is fitted and fixed by fitting the end of the cleaning port 2 into the branch pipe portion 33, and the linear member guide mechanism 1 is screwed into the tip of the fixed cleaning port 2. In the threaded guide guide mechanism 1 screwed in, the rib groove 15 abuts against the tip of the cleaning port 2, whereby the protruding portion 12 of the linear guide guide cylinder portion 11 is bent obliquely upward, and the opening of the protruding portion 12 is opened. Is fixed at a fixed position that is higher than the center of the cap portion 10. The opening of the protrusion 12 is closed by a detachable closing lid 16a.

The standing pipe structure constructed in this way is used as follows.
As shown in FIG. 1, the opening of the protrusion 12 is opened by removing the closing lid 16a, and the filament 6 is inserted. The inserted wire rod 6 advances toward one end opening of the wire rod guide tube portion 11 while being regulated and guided by the wire rod guide tube portion 11. In addition, the wire 6 points out the instrument which has the flexibility which makes | forms an elongate line | wire, such as a wire with a cleaning instrument, or a fiberscope, and bends in any direction by force.

  When the wire rod 6 exits from the one end opening of the wire rod guide tube portion 11, it is released from the regulation guide by the wire rod guide tube portion 11, and starts to bend and deform in the direction of gravity due to its own weight. The wire rod 6 that has started bending deformation falls toward the pipe line of the downstream vertical pipe 41. The wire rod 6 in the pipe line of the standpipe 41 is put into and out of operation by the operator's operation, and the deposits attached to the inner peripheral surface of the standpipe 41 are removed.

The vertical pipe structure used in this way has the following effects.
Since the opening of the projecting portion 12 is smaller than the diameter of the cleaning port 2, even when the cleaning port 2 is in an open state, the drainage flowing down the standpipe 4 is less likely to leak than when the cleaning port 2 is in a fully open state.

  Since the opening of the protruding portion 12 is provided at a position higher than the center of the cap portion 10, the wire rod 6 inserted into the opening of the protruding portion 12 is regulated and guided at a position higher than the corner portion 32. The wire 6 that starts to bend in the direction of gravity after the guide is prevented from coming into contact with the corner portion 32. Even when the wire rod 6 is in the insertion / removal operation state, the corner portion 32 is not scraped off and the durability of the pipe joint 3 is not lowered.

  Moreover, since the protrusion part 12 is curving upwards, while making insertion operation of the wire 6 easy, even if opening becomes an open state, the waste_water | drain which flows down the standpipe 4 becomes difficult to leak.

  Moreover, since the closing lid 16a and the wire rod guide mechanism 1 have a screw structure and can be easily attached and detached, for example, when the wire rod 6 is inserted, the closing lid 16a is removed and the wire rod 6 When inserting a large-sized object, the wire rod guide mechanism 1 can be removed and the cleaning port 2 can be fully opened.

  In addition, the wire rod guide cylinder part 11 which concerns on this invention is not limited to the shape mentioned above, It regulates so that the wire rod 6 which deform | transforms may not contact the corner part 32 of the pipe joint 3.

Embodiment 2. FIG.
In the first embodiment described above, an example in which the pipe joint 3 is incorporated in the middle of the standing pipe is shown, but the present invention is not limited thereto, and the pipe joint 3 can be incorporated in the middle of the horizontal pipe. Assumed.

  FIG. 12 is a view showing an example in which a conventional pipe joint C is incorporated in the middle of a horizontal pipe line. As shown in FIG. 12, in the conventional pipe structure, the pipe joint C is provided with the opening of the branch pipe portion C1 facing upward so that the drainage flowing through the pipe of the horizontal pipe B does not spill out. Therefore, when the space for inserting the wire rod (referred to as a space surrounded by a dotted line in the figure) cannot be secured between the pipe joint C and the ground G, the installation place of the pipe joint C is changed. It is necessary to take measures such as opening an inspection opening on the ground G.

  FIG. 8 is a view showing an example in which the pipe joint 3 according to the present invention is incorporated in the middle of a horizontal pipe line. As shown in FIG. 8, by attaching the wire guide mechanism 1 to the opening of the branch pipe part 33, the opening of the branch pipe part 33 can be installed in the horizontal direction without fear of leakage of drainage, and the installation location is changed. The insertion work space can be secured without opening the inspection opening in the ground G. That is, since the insertion opening of the wire 6 is located at a position higher than the center of the cap portion 10, drainage flowing at least at a position lower than the center of the cap portion 10 does not leak outside.

  In addition, since it is the same as the standing pipe structure shown in Embodiment 1 about another location, the same code | symbol is attached | subjected to a corresponding location and the description is abbreviate | omitted.

Embodiment 3 FIG.
In the present invention, the receiving portion 31 of the pipe joint 3 may have the following structure. FIG. 9 is a perspective view showing an example in which the expansion / contraction treatment member 7 is attached to the pipe joint 3 according to the present invention, and FIG. 10 is a view showing a linear tool guide mechanism having a shape different from those shown in FIGS. ) Shows a front view, (b) shows a side view including a cross section, and FIG. 13 shows an example in which an insertion socket I for absorbing the linear expansion of the vertical pipe A is attached to a conventional pipe joint C. is there.

  The standpipe A formed of a heat-flexible resin has a very large linear expansion coefficient and greatly expands and contracts depending on the temperature. Therefore, as shown in FIG. 13, the conventional pipe structure absorbs stress due to expansion and contraction by interposing an elastic insertion socket I between the vertical pipe A and the pipe joint C, and breaks the pipe joint C. Is preventing. However, in such a structure, since a large number of plug sockets I are required, the construction cost increases. Further, in such a structure, if the mounting state of the insertion socket I is poor, the drainage may leak from the mounting location.

  Therefore, in the vertical pipe structure according to the present invention, as shown in FIG. 9, the stress due to expansion and contraction of the vertical pipe 4 is absorbed in the receiving portion 3 of the pipe joint 3 instead of interposing the insertion socket I. The expansion / contraction processing member 7 is provided.

  The expansion / contraction treatment member 7 is formed of an elastic material such as ethylene-propylene-diene rubber (EPDM), and includes a main body portion 70, a check valve 71, and a pipe connection portion 72. The main body 70 has a substantially cylindrical shape, and its outer diameter is substantially the same as the diameter of the receiving portion 31 of the pipe joint 3. The tube connecting portion 72 protrudes obliquely upward from the upper end of the main body portion 70 and has a trumpet shape. The check valve 71 protrudes obliquely downward from the upper end of the main body 70 to form a reverse taper shape, and a plurality of grooves are formed on the surface thereof. In the expansion / contraction processing member 7, the main body portion 70 is fitted into the receiving portion 31 of the pipe joint 3.

  When the pipe joint 3 is incorporated in the middle of the vertical pipe, the pipe joint 3 is installed so that the receiving portion 31 including the expansion / contraction processing member 7 faces upward, and the end of the upstream side vertical pipe 40 faces upward. It is fitted into the pipe connection part 72 of the expansion / contraction processing part 7. The vertical pipe 40 fitted into the pipe connection portion 72 is inserted to a position where the end edge pushes the check valve 71 and is fixed to a fixed position by the gripping force of the check valve 71.

  The fixed standing pipe 40 is in a watertight state with the expansion / contraction processing member 7 due to the gripping force of the check valve 71, and prevents water leakage from the connection point with the expansion / contraction processing member 7. In addition, the expansion / contraction processing member 7 is brought into close contact with the inner peripheral surface of the receiving portion 31 when the check valve 71 is pushed and expanded by the standing pipe 41 so that the main body portion 70 is expanded downward. And become watertight.

  In addition, the pipe joint 3 which concerns on Embodiment 1 thru | or 3 mentioned above can be changed to the wire rod guide mechanism 8 different from the wire rod guide mechanism 1. FIG. As shown in FIG. 10, the wire rod guide mechanism 8 includes a cap portion 80, a wire rod insertion port 81, a handle portion 82, an annular rib 83, and a male screw 84.

  The cap portion 80 has a disk shape larger than the diameter of the cleaning port 2, and a wire rod insertion port 81 having a smaller diameter W than the diameter of the cleaning port 2 passes through the center of the disk. The wire rod penetration port 81 is closed by a detachable closing lid (not shown). A plurality of cap portions 80 are attached in the vicinity of the outer peripheral edge of the front surface so that the handle portion used for the screwing operation surrounds the wire rod insertion port 81. An annular rib 83 whose outer diameter is substantially the same as the diameter of the cleaning port 2 is formed on the back surface of the cap portion 80, and a male screw 84 is formed on the outer peripheral surface.

  As shown in FIG. 9, in the wire rod guide mechanism 8, an annular rubber member 85 having an O shape in cross section is attached to the outer peripheral surface of the annular rib 83 and screwed into the distal end portion of the cleaning port 2 for water stop. . The threaded rod guide mechanism 8 screwed in is in a watertight state between the annular rubber member 85 and the cleaning port 2 when the tip of the cleaning port 2 is pressed, and prevents water leakage from the screwed portion. The wire rod 6 is inserted from the wire rod insertion opening 81 in a state of being closed by the wire rod guide mechanism 8.

  In this way, the wire rod guide mechanism 8 is attached to the cleaning port 2, and thus the wire rod 6 is inserted from the wire rod insertion port 81 having a diameter smaller than the diameter of the cleaning port 2. The drainage flowing down from the pipe to the branch pipe section 33 hardly leaks to the outside.

  In addition, the pipe joint 3 according to the first to third embodiments described above is cleaned when the wire guide guide mechanism 1 (or 8) is removed when a larger water stop jig or the like than the wire 6 is inserted. It is assumed that the mouth 2 is fully opened.

  As a case for inserting a thing larger than the wire rod 6, a full water test of the pipeline is raised. In the pipe full water test, a ball-shaped water stop jig that can swell like a balloon is inserted into the pipe joint 3 and the pipe 3 is blocked by the inserted water stop jig. This is a test to check water leakage upstream from the interception point by letting the drainage flow with the road shut off.

  Further, the wire rod guide mechanism 1 (or 8), the cleaning port 2, the pipe joint 3, the vertical pipe 4 and the horizontal pipe 5 according to the above-described embodiment are each formed of a flexible material. However, in order to satisfy these requirements, Article 129-2-5 paragraph 7a and i of the Building Standard Act, which stipulate that pipes installed under the prescribed environment should be fireproof. It is preferable to provide a fireproof structure.

  Moreover, in embodiment mentioned above, although the cleaning port 2 is demonstrated as an insertion port of the filament 6, you may utilize as an inspection window for inspecting a pipe line.

  In addition, the filament guide mechanism 1 (or 8) may be worn by the filament 6 in which the end of the filament guide tube 11 (or the filament insertion port 81) is in the insertion / removal operation state. However, since it is easy to attach and detach as described above, the operator can quickly replace the new wire rod guide tube portion 1 (or 8).
