Description

  The present invention relates to a basic through-pipe structure in which a negative pressure is unlikely to be generated in a drain pipe under the floor, and the drainage hardly flows back through an outdoor drain pipe, and a swirl type drainage basin used therefor.

  Conventionally, drainage pipes from water facilities such as toilets, washstands, bathrooms, and kitchens in the home are piped under the floor of the house, and the drainage pipe under the floor penetrates the foundation of the house and is buried outdoors. There is known a piping structure that connects to (for example, Patent Document 1). In such a piping structure, there is a large drop between the drainage pipe penetrating the foundation of the house (hereinafter referred to as the foundation penetration drainage pipe) and the connection port of the drainage basin, so that the vertical drainage is connected to the foundation penetration drainage pipe through a 90 ° elbow joint. In addition to connecting the pipe, a horizontal drain pipe is connected to the lower end of the vertical drain pipe via a 90 ° elbow joint, and this horizontal drain pipe is connected to the connection port of the drain. Although not shown, in such a pipe structure, in addition to the above two 90 ° elbow joints, a substantially horizontal pipe below the floor is turned downward in the foundation through drain pipe so It is necessary to connect a 90 ° elbow joint.

However, in the above piping structure, if a large amount of water is flowed at once, for example, flushing toilets and toilets at the same time, the portion bent by 90 ° at the elbow joint is blocked by drainage and the ventilation in the drainage pipe is blocked. Therefore, there is a problem that negative pressure is generated in the drain pipe under the floor and the sealing water in the trap of the toilet or the washstand is destroyed.
JP 2003-96857 A

  The present invention has been made to cope with the above-mentioned problems, and since there is hardly any negative pressure in the drainage pipe under the floor, there is almost no fear of causing the sealing failure of the water facility, and the drainage smoothly flows into the outdoor drainage pipe. The problem to be solved is to provide a basic through-pipe structure that hardly flows back to the upstream side in order to join together, and a swirl type drainage basin used therefor.

  In order to solve the above problems, the basic through-pipe structure according to the present invention has a swirl flow pipe joint that generates a swirl flow inside the foundation of a house and a swirl flow that generates a swirl flow outside the foundation. -Type drainage pipe, foundation drainage pipe that penetrates the foundation through the drainage pipe under the floor at the connection port formed on the side wall of the swirl type pipe joint, and the connection port formed at the bottom wall of the swirl type pipe fitting The upstream end of the swirl-flow drainage basin is connected to the upper connection port formed in the upper part of the side wall of the swirl-flow drainage basin. The drainage pipes are connected to each other.

  In the basic through-pipe structure of the present invention, the upstream end of the substantially horizontal basic through-drain pipe and the connection port formed in the bottom wall of the swirl type pipe joint are connected via a large bend pipe. Preferably it is. Further, the upstream end of the basic through-drainage pipe that rises in the direction of approximately 45 ° on the upstream side and the connection port formed in the bottom wall of the swirl type pipe joint are connected via a 45 ° elbow joint. It is also preferable.

  The swirling flow drainage basin of the present invention used for this basic through-pipe structure is a drainage basin that generates a swirling flow that includes an upper height-adjusting vertical cylindrical body and a lower dredge main body, The height-adjusting vertical cylindrical body is formed by shifting the upper connection port to one side of the vertical cylindrical body on the side wall, and the lower saddle body bulges the side wall into a substantially semi-cylindrical shape. By doing so, a sideways flowing water passage portion is formed on one side of the dredge body, and a partition wall is formed between the inside of the opposite side of the dredge body and the upstream passage portion of the flowing water passage portion, and both ends of the flowing water passage portion. It is characterized in that a lower connection port is formed on the surface.

  In the swirling flow drainage basin according to the present invention, it is preferable to attach a cover plate that covers at least the upstream side passage portion of the water flow passage portion in the upper opening of the basin body. It is preferable to attach so that there is no gap between the upper end of the wall. This cover plate may be directly attached in the upper opening of the bag body, but the cover plate is fixed inside the annular frame, or the cover plate is provided inside the annular frame so that it can stand up and down, It is preferable that the cover plate is attached in the upper opening by fitting the annular frame in the upper opening of the bag main body. Moreover, it is preferable that the annular frame provided with the cover plate on the inner side is freely attachable / removable through the upper cylindrical body for height adjustment. As a preferable specific example of the cover plate, a semicircular cover plate that covers one side of the main body with the flowing water passage portion of the upper opening, or one side of the main body with the flowing water passage portion of the upper opening. Examples include a semi-doughnut plate-like cover plate that covers the inner peripheral edge, and a projecting piece-like cover plate that covers only the upper portion of the upstream passage portion of the flowing water passage portion. Furthermore, in the swirling drainage according to the present invention, a step is formed at the boundary between the bottom surface of the upstream passage portion and the bottom surface of the downstream passage portion of the flowing water passage portion of the main body, and the bottom surface of the upstream passage portion. Is preferably higher than the bottom surface of the downstream passage portion.

  In the basic through-pipe structure of the present invention, the drainage flowing into the swirl type pipe joint from the underfloor drain pipe (hereinafter referred to as the underfloor drain pipe) becomes a swirl flow, and passes through the basic through drain pipe to the upper part of the swirl drain It flows into the drainage basin from the connection port and is again swirled and drained downstream of an outdoor drainage pipe (hereinafter referred to as an outdoor drainage pipe). When a swirling flow is generated by the swirling flow type pipe joint in this way, an air core is formed at the center of the swirling flow, and the wastewater that generated this swirling flow flows smoothly into the foundation through drainage pipe. The through drainage pipe is less likely to be blocked, and a swirling flow is generated even in a swirling drainage, so that there is no need to worry about blocking in the drainage. Therefore, according to the basic through-pipe structure of the present invention, it is easy to ensure ventilation in the pipe, and unless a large amount of water is drained at one time, negative pressure is not generated in the underfloor drain pipe due to blockage. It is possible to prevent water seal damage to water facilities such as washstands, bathrooms, and kitchens.

  In particular, when the upstream end of the basic through-drain pipe and the connection port formed on the bottom wall of the swirl type pipe joint are connected via a large bend pipe, or approximately 45 ° direction on the upstream side. If the upstream end of the basic through-drain pipe that rises to the bottom and the connection port formed in the bottom wall of the swirl-flow type pipe joint are connected via a 45 ° elbow joint, The generated swirling flow smoothly flows from the large bend pipe and the 45 ° elbow joint to the upstream side of the foundation penetrating drain pipe in the 45 ° direction, flows through the foundation penetrating drain pipe, and flows into the swirling drain Therefore, it becomes more difficult to be blocked, and the effect of preventing sealing water destruction is further improved.

In addition, in the basic through-pipe structure of the present invention, when the direction of the swirling flow generated in the swirling flow drainage basin is matched to the flow direction of the outdoor drainage pipe, the drainage smoothly merges with the outdoor drainage pipe and flows downstream. It becomes difficult for some of the drainage to flow back to the upstream side of the outdoor drainage pipe.
In that case, like the swirling flow drainage basin of the present invention, the side wall of the culvert body is swelled in a substantially semi-cylindrical shape to form a lateral water passage portion on one side of the basin body, If a partition wall is formed between the interior and the upstream passage portion of the flowing water passage portion, the waste water flowing down in the drainage basin while turning will almost always flow into the upstream passage portion of the flowing water passage portion by the partition wall. Therefore, it is possible to almost certainly prevent a part of the drainage from flowing backward from the upstream passage portion to the upstream side of the outdoor drain pipe.

  In particular, the swirl type drainage basin in which a cover plate that covers at least the upper side of the upstream passage portion of the flowing water passage portion is mounted in the upper opening of the main body of the dredging body, the drainage from the upper side of the flowing water passage portion by this cover plate. All the drainage that has flowed down to the bottom of the main body while turning is joined to the downstream passage part of the flowing water passage part by the partition wall, and more reliably drained to the downstream side of the outdoor drainage pipe. be able to. In that case, if the cover plate is mounted so that there is no gap between the upper end of the partition wall, the drainage may flow into the upstream passage portion of the flowing water passage portion from between the cover plate and the upper end of the partition wall. Therefore, the backflow prevention effect is further improved. And the swirling flow type drainage basin in which a step portion is formed at the boundary between the bottom surface of the upstream passage portion and the bottom surface of the downstream passage portion, and the bottom surface of the upstream passage portion is higher than the bottom surface of the downstream passage portion. Since it is difficult for the drainage that has joined the downstream passage portion of the flowing water passage portion to reach the upstream passage portion due to the stepped portion, the backflow prevention effect becomes more remarkable.

  In addition, the cover plate is fixed inside the annular frame, or is provided so as to be able to stand up and down on the inside of the annular frame, and this annular frame is fitted into the upper opening of the heel body so that it can be mounted in the upper opening. The swirl type drainage basin is easier to install compared to the case where the cover plate is directly installed in the upper opening of the basin body. In particular, the cover plate is installed inside the annular frame so that it can stand upside down. Since the cover plate can be erected to easily clean the bottom of the swirling flow drainage basin and the flowing water passage, maintenance is easy. The swivel drainage basin with an annular frame provided with a cover plate that can be freely attached and removed through a vertical cylinder for adjusting the height of the upper part can also be removed by removing the annular frame provided with a cover plate to the outside. Maintenance is easy because the bottom of the ridge and the running water passage can be easily cleaned.

FIG. 5 is a plan view with the lid of the swirl type pipe joint removed, and FIG. 6 is a cross section showing an embodiment of the swirl type drainage basin of the present invention used in the piping structure. 7 is an exploded cross-sectional view of the swirling flow drainage basin, FIG. 8 is a plan view of the swirling flow drainage tub with the vertical cylindrical body removed, and FIG. 9 is a dredging main body of the swirling flow drainage basin. 10 is a cross-sectional view taken along line AA in FIG. 9, FIG. 11 is a cross-sectional view taken along line BB in FIG. 9, and FIG. 12 is a cross-sectional view taken along line CC in FIG.

  In the foundation through-pipe structure shown in FIG. 1, reference numeral 1 denotes a cloth foundation of a house, and a swirling flow type pipe joint 3 that generates a swirling flow is disposed in an unboxed portion 2 a of the soil concrete 2 inside the cloth foundation 1. Has been. An underfloor drain pipe 4 piped on the underfloor concrete 2 is connected to a connection port 3 a formed in the side wall of the swirl type pipe joint 3, and is formed on the bottom wall of the pipe joint 3. Connected to the connection port 3b is a 90 ° large bend pipe 6 connected to the upstream end of the basic through drain pipe 5. As shown in FIG. 2, drain pipes 4 a and 4 b from water facilities such as a washroom 10 and a toilet 11 are connected to the underfloor drainage pipe 4. Sealing water is supplied to these washroom 10 and the toilet 11. (Not shown) is provided.

  As shown in FIG. 1, a swirl type drainage basin 7 that generates a swirl flow is embedded in the ground outside the fabric foundation 1, and the upper part formed on the upper side wall of the swirl type drainage basin 7. The downstream end of the foundation penetration drain pipe 5 that penetrates the foundation 1 is connected to the connection port 7a. As shown in FIG. 2, an upstream outdoor drain pipe 8a and a downstream outdoor drain pipe 8b are connected to the lower connection ports 7b and 7c formed in the lower part of the swirl type drainage basin 7. .

  The swirl type pipe joint 3 is formed of a synthetic resin, and as shown in FIGS. 3 to 5, the opening upper part 3 d is formed in an annular shape, and the annular opening upper part 3 d. A circular lid 3c made of synthetic resin with a handle is detachably fitted. Then, as shown in FIG. 5, the lower side wall 3e of the annular opening upper portion 3d is formed in a spiral shape so that the radius of curvature gradually decreases from the middle and reaches the connection port 3b in the center of the bottom wall 3f. The starting end and the terminal end of the spiral side wall 3e are connected by a flat vertical wall 3g. And the connection port 3a which connects the underfloor drain pipe 4 is deviated to one side of the swirl type pipe joint 3 and protrudes in parallel with the vertical wall 3g from the lower part on the start end side of the side wall 3e. Accordingly, the waste water flowing into the swirl type pipe joint 3 from the underfloor drain pipe 4 connected to the connection port 3a generates a swirl flow along the spiral side wall 3e, forms an air core, and forms the center of the bottom wall 3f. It flows down to the large bend pipe 6 from the connection port 3b. Further, when the connection port 3a is projected from the lower part on the start end side of the side wall 3e as in the swirl type pipe joint 3, the connection port 3a on the inflow side and the connection port 3b on the outflow side in the center of the bottom wall are connected. Since the difference in height is slight, the height of the underfloor drain pipe 4 can be kept low, and construction is possible even when the difference between the underfloor floor level and the outdoor ground level is small. The lid body 3 is not limited to the fitting type lid body as shown in the figure. For example, various types of lid bodies such as flange-type lid bodies that can be attached and detached with bolts and nuts are adopted. Can do.

  The large bend pipe 6 preferably has a radius of curvature of 100 mm or more. Since such a large bend pipe 6 has a much larger radius of curvature than that of a 90 ° elbow joint, the drainage that generates the swirl flow is large. The inside of the bent pipe 6 flows down smoothly and flows into the outdoor swirl type drainage trough 7 through the foundation through drain pipe 5. Therefore, unless a very large amount of drainage flows at a time, the large bend pipe 6 and the foundation through drain pipe 5 are not blocked by the drainage, and the ventilation in the pipe is ensured.

  As shown in FIGS. 6 and 7, the swirling drainage basin 7 embedded in the outdoor ground has an upper cylindrical body 7 d for height adjustment, a lower main body 7 e, and an intermediate cylindrical body. 7f, a synthetic resin drainage basin composed of an upper lid receiving frame 7g and a lid body 7h. An intermediate cylinder 7f is fitted and connected to an upper opening 7i of the casket body 7e, and the intermediate cylinder 7f is connected to the intermediate cylinder 7f. The small-diameter lower portion 7j of the vertical cylinder 7d for height adjustment is fitted and connected, and a lid receiving frame 7g is fitted into the vertical cylinder 7d, and the lid 7h is attached to the lid receiving frame and assembled. .

  The vertical cylinder 7d on the upper side of the swirling drainage 7 adjusts the overall height of the swirling drainage 7 so that the lid 7h attached to the lid receiving frame 7g is exposed to the ground. In addition, several cutting lines (not shown) are provided around the upper outer peripheral surface of the vertical cylindrical body 7d with a certain vertical distance, and the vertical cylindrical body is located at a cutting line having a desired height. By cutting 7d, the total height of the swirling drainage can be easily adjusted. As shown in FIGS. 6 to 8, an upper connection port 7a is provided on the side wall of the vertical cylindrical body 7d so as to be deflected to one side of the vertical cylindrical body 7d so as to be slightly curved. As shown in FIGS. 1 and 2, the downstream end of the basic through drain pipe 5 is connected to 7 a. Therefore, the waste water that has flowed into the swirling flow type drainage trough 7 from the basic through drainage pipe 5 flows down to the lower dredge main body 7e while generating a swirling flow along the inner peripheral surface of the vertical cylindrical body 7d.

  Further, the intermediate cylindrical body 7f of the swirling flow drainage basin 7 is cut to a desired length so that the upper connection port 7a is at the same height as the downstream end of the basic through drainage pipe 5. And the height position of the upper connection port 7a of the vertical cylinder 7d and the depth position of the rod body 7e are set so that the lower connection ports 7b, 7c of the rod body 7e have the same depth as the outdoor drain pipes 8a, 8b. Each one is to be adjusted. The vertical cylindrical body 7d is extended downward as it is without forming the small-diameter lower portion 7j in the vertical cylindrical body 7d, and several cutting lines are provided around the extended lower outer peripheral surface with a certain vertical interval. Even if the intermediate cylinder 7f is not used, the upper connection can be achieved by cutting the extension lower part of the vertical cylinder 7d at the desired cutting line and fitting and connecting it to the upper opening 7i of the flange body 7e. The height position of the mouth 7a and the depth position of the heel body 7e can be adjusted.

  As shown in FIGS. 9 to 12, the dredging main body 7e of the swirling flow drainage dredger 7 forms a lateral flowing water passage portion 7k on one side of the dredging main body by expanding the side wall 7s on one side into a substantially semi-cylindrical shape. In this case, a partition wall 7m is formed between the inside opposite to the main body 7e and the upstream passage portion of the flowing water passage portion 7k. Then, as shown in FIGS. 9 and 11, a stepped portion 7q obliquely crosses the flowing water passage portion 7k at the boundary between the bottom surface of the upstream passage portion 7n and the bottom surface of the downstream passage portion 7p of the flowing water passage portion 7k. The bottom surface of the upstream passage portion 7n is higher than the bottom surface of the downstream passage portion 7p. Further, lower connection ports 7b and 7c are formed at both ends of the flowing water passage portion 7k. As shown in FIG. 2, an upstream outdoor drain pipe 8a is connected to the downstream side lower connection port 7b on the downstream side. A downstream outdoor drain pipe 8b is connected to each lower connection port 7b.

  Further, as shown in FIGS. 9, 10 and 12, the upper opening 7i of the bag main body 7e is made of a synthetic resin that covers one side of the upper opening 7i where the flowing water passage portion 7k is formed. The semicircular cover plate 7r is attached so as not to create a gap between the upper end of the partition wall 7m. As shown in FIG. 9, the semicircular cover plate 7r can be stood and laid down as shown in FIG. 12 by fitting the convex portions 7t at both ends into the vertical grooves on the inner surface of the bag main body 7k. As shown in FIG. 10, it is attached so as to be gradually lowered toward the downstream side.

  When the main body 7e of the swirling flow type drainage basin 7 is configured as described above, the drainage that has flowed down to the main body 7e while swirling along the inner peripheral surface of the vertical cylindrical body 7d is separated by the partition wall 7m. 7k is prevented from flowing into the upstream passage portion 7n and merges with the downstream passage portion 7p of the flowing water passage portion 7k, and the wastewater merged with the downstream passage portion 7p is transferred to the upstream passage portion 7n by the step portion 7q. Therefore, the backflow from the upstream passage portion 7n to the upstream outdoor drain pipe 8a is eliminated. The semicircular cover plate 7r attached so as not to create a gap with the upper end of the partition wall 7m prevents the inflow of drainage from above into the flowing water passage portion 7k, and all the drainage flowing down while turning. Flows into the downstream passage portion 7p of the flowing water passage portion 7k through the partition wall 7m as described above, so that the water can be reliably drained to the outdoor drain pipe 8b on the downstream side. Further, when a swirl flow is generated in the swirl type drainage basin 7, there is no fear of blockage in the drainage basin 7, so that the large bend pipe 6 and the basic through drainage pipe 5 are not blocked as described above. As a result, ventilation over the entire piping is ensured, and the sealing failure of the water facility due to blockage can be reliably prevented. In addition, when the semicircular cover plate 7r is erected, the flowing water passage portion 7k can be easily cleaned, so that maintenance is easy.

  FIG. 13 is a cross-sectional view showing another embodiment of the basic through piping structure according to the present invention.

  This basic through-pipe structure is a base through drainage pipe made of a flexible pipe that rises in the 45 ° direction on the upstream side and is embedded in the solid foundation 10 of the house with a sheath tube 9 rising in the 45 ° direction on the upstream side. 50 is inserted into the sheath tube 9, and the upstream end of the basic through-drainage pipe 50 and the connection port 3 b formed in the bottom wall of the swirl type pipe joint 3 are connected via a 45 ° elbow joint 60. Connected. Other configurations are the same as those of the basic through-pipe structure of the above-described embodiment shown in FIG. 1, and therefore, the same members are only given the same reference numerals in FIG.

  In such a basic through-pipe structure, the swirling flow generated by the swirling flow type swirling pipe fitting smoothly flows down the upstream side of the basic through-drain pipe 50 rising in the 45 ° direction and flows through the basic through-drain pipe 50. Since it flows into the swirl type drainage basin 7 and turns into a swirl flow again and is drained to the outdoor drainage pipe, as with the basic through-pipe structure of the embodiment shown in FIG. In addition, the backflow to the upstream side of the outdoor drain pipe can be almost surely prevented.

  In addition, in the foundation through-pipe structure of the embodiment shown in FIG. 1, instead of the foundation through-drain pipe 5 and the large bend pipe 6, a foundation through-drain pipe that rises 90 ° while being curved on the upstream side is made to penetrate the fabric foundation 1. You may comprise so that the upstream edge part of this basic penetration drainage pipe may be connected to the connection port 3b of the bottom wall center of the swirl type pipe joint 3, and the same effect is obtained also in that case.

  The swirl type drainage basin 7 in the above embodiment has a semicircular cover plate 7r directly attached to the upper opening 7i of the casket main body 7e so as to be able to stand up and down, but as shown in FIG. A semicircular cover plate 7r is provided on the inner side of 7u so as to be able to stand up and down, and like this swirl type drainage trough 7 of the embodiment shown in FIGS. 14 and 15, this annular frame 7u is placed in the upper opening 7i of the trough body 7e. You may attach by carrying out internal fitting.

  More specifically, the annular frame 7u is a synthetic resin perfect circular annular frame having an outer diameter that can be fitted into the upper opening 7i of the collar body 7e substantially without any gap. As shown, an inner collar 7v is formed at the inner lower end of the annular frame 7u. Then, the semicircular cover plate 7r is erected and laid down by fitting the shaft portions of the blocks 7w and 7w attached to both ends of the semicircular cover plate 7r to the bearing portion 7y on the inner surface of the annular frame 7u. The cover plate 7r is attached to the inner side of the annular frame 7u, and the peripheral edge of the cover plate 7r is locked to the inner flange 7v of the annular frame 7u. As shown in FIGS. 14 and 15, the annular frame 7u provided with the semicircular cover plate 7r so as to be able to stand up and down is provided with the cover plate 7r on the flowing water passage portion 7k side and the upper opening 7i of the eaves body 7e. Since the above-mentioned intermediate cylinder 7f is fitted and connected to the lower opening of the upper opening 7i, it can be easily mounted in the upper opening 7i. In addition, the cover plate 7r can be erected to easily clean the bottom portion of the eaves body 7e and the flowing water passage portion 7k, so that maintenance is easy.

  Each of the cover plates 7r is a semicircular cover plate that covers one side of the upper opening 7i of the main body 7e where the flowing water passage 7k is formed. Is not limited to the semicircular cover plate described above, and may be any cover plate that covers at least the upper side of the upstream passage portion 7n of the flowing water passage portion 7k of the main body 7e. Accordingly, a semi-doughnut plate-like cover plate 7r as shown in FIG. 17, which covers the inner peripheral edge of the side where the flowing water passage portion of the upper opening 7i of the bag body is formed, or a protrusion as shown in FIG. A piece-like cover plate 7r that covers only the upper side of the upstream passage portion 7n of the flowing water passage portion 7k of the main body is also preferably employed.

  The half donut plate-like cover plate 7r in FIG. 17 is formed by widely forming one half of the cover plate 7r so as to reliably cover the upstream passage portion 7n of the flowing water passage portion 7k. The shafts of the blocks 7w and 7w attached to both ends are pivotably fitted into the bearings 7y on the inner surface of the annular frame 7u, so that they can be stood and tilted inside the annular frame 7u. The peripheral edge of the cover plate 7r is locked to the inner flange 7v of the annular frame 7u. The annular frame 7u provided with the semi-doughnut-like cover plate 7r so that it can stand up and down is also fitted into the upper opening 7i of the eaves body 7e with the cover plate 7r facing the flowing water passage portion 7k. Since the intermediate cylinder 7f can be easily attached in the upper opening 7i by fitting and connecting, the mounting work is easier than in the case where the cover body is directly attached in the upper opening, and the cover plate 7r is raised. Since the bottom of the bowl main body 7e and the flowing water passage 7k can be easily cleaned, maintenance is easy. The half donut plate-like cover plate 7r shown in FIG. 17 has a wide half on one side, but it is of course possible to form a wide half donut plate as a whole.

  On the other hand, the cover plate 7r of FIG. 18 is a protruding piece that covers only the upper side of the upstream passage portion 7n of the flowing water passage portion 7k of the main body, and is integrally formed with the annular frame 7u with synthetic resin. . Such a projecting piece-like cover plate 7r alone is difficult to attach directly to the upper opening 7i of the bag main body, but if the annular frame 7u and the cover plate 7r are integrally formed as described above, the annular frame 7u can be easily attached by being fitted into the upper opening 7i of the bag main body.

  Moreover, what provided the cover board inside the cyclic | annular frame is good also as attachment and taking-out through the vertical cylinder 7d for height adjustment of the upper side of a swirl type drainage basin. FIG. 19 shows an example. A semicircular cover plate 7r is integrally provided inside the annular frame 7u, and a screw cylinder 7x having an internal thread formed on the inner surface is positioned at the center of the annular frame 7u. It is erected from the plate 7r. In such a cover plate with a screw cylinder, a screw rod having a male screw formed at the tip is screwed into the screw tube 7x, and the upper cylindrical body 7d of the swirling flow drainage rod is inserted into the upper opening 7i of the rod body 7e. It can be attached, and when cleaning, it can be easily pulled out from the upper opening 7i by pulling up with a screw rod, so that maintenance is easy. Of course, the semicircular cover plate 7r may be attached to the inside of the annular frame 7u so as to be able to stand up and down like FIG.

  As can be understood from the above description, according to the basic through-pipe structure of the present invention, the waste water flowing into the swirl type pipe joint from the underfloor drain pipe becomes a swirl flow, forms an air core, and closes the basic through pipe and the like. It flows smoothly without draining, and even swirl type drainage traps generate swirl flow and drain smoothly into the outdoor drain pipe on the downstream side. It is possible to prevent the sealing water from being broken, and the swirl type drainage basin can effectively prevent the backflow of the drainage to the outdoor drainage pipe on the upstream side.
