SOLUTION: An advection tube 1 for connecting a large-sized sewage treatment tank 2 and another similar tank 3 is constituted by a flexible tube 10 having a spigot at both ends, and the flexible tube 10 is locked at a distal end. A strip consisting of a thin shaft with claws and a bag with this thin shaft protruding is composed of a tubular body that is rolled and extended in a circular shape. By simultaneously exerting the arbor function and the S-curve function, the difficulty in centering the two tanks 2 and 3 is overcome.

Description of the Related Art Generally, in areas without public sewerage facilities, wastewater discharged from houses and factories must not be discharged into public waters unless it is purified. Therefore, as individual treatment for purification of domestic wastewater, graywater wastewater treatment only to treat domestic wastewater only, merger treatment to treat domestic wastewater and human waste together, and human waste in a single human waste purification tank, Three types of processing are performed, namely, irregular merger processing in which treated water and household wastewater are processed together.

The septic tank shown in FIG. 4 is of a type in which a standardized product manufactured by a production factory is carried into the site and buried therein, and is particularly used for anaerobic filter bed contact aeration (anaerobic filter bed → contact aeration tank → sedimentation tank → disinfection tank). And the BOD (biochemical oxygen demand) concentration of the effluent from 20 mg / liter to 10
It is a combination of a tertiary treatment tank for purifying to less than mg / liter.

And sewage plumbing by experts from different industries, and these tanks are huge (for example, about 2 m in height, about 3 m in length in the upstream and downstream directions), and it is difficult to center vertically, horizontally, and horizontally. In addition, because the installation cannot be easily reworked, various errors occur in the advection tube 113 that connects the two tanks, and it is difficult to connect the two tanks even if the equipment is installed by a septic tank facility engineer. There was a problem that.

A prefabricated inexpensive PVC component is assembled at a production plant, and its structure is, as shown particularly in FIG. 2, connected to a socket (or spigot) of the tank-attached socket 8 at one end by adhesive bonding at a construction site. A short pipe 12 to be connected, and a receiving joint 13 to which the other end of the connecting short pipe 2 is adhesively bonded at a production plant. The receiving joint 13 is connected to the socket 20 of the flexible tube 10 by the production plant. It is designed to be adhesively bonded. Of course, the adhesive bonding may be rubber ring bonding.

However, when applied to the size of a pipe for water supply or sewage (for example, 75 mmφ to 350 mmφ), it is difficult to simultaneously perform the jarring function and the S-shaped curve function.

It is an extruded product using P resin, and its structure is such that a thin shaft 14 having a thickness of about the thickness of a PVC pipe (VP) is formed into a pentagonal cross section in a side sectional view as shown in FIG. A bag (also referred to as a bud) 15 is integrally formed to protrude from the head.

特許第２７３２３７４号公報参照）。In this structure, the shaft 14 is pushed open (watertight) against the resin elasticity into the rightward opening 17 of the bag body 15a to be wound next, and loosely fitted.
An arrow-shaped claw (locking claw) 18 provided at the tip of the shaft 14 is locked inside the opening 17 to prevent it from coming off and integrated. Thus, the tubular flexible tube 10 is formed (see, for example, Japanese Patent No. 2732374).

Until the arrow-shaped claw 18 is locked to the shaft 14, the shaft 14 is within the cavity of the bag body 15 (a cavity having substantially the same axial length as the shaft 14) in a range of approximately the axial length of the shaft 14 in parallel with its central axis a. You can move.

い。In particular, in the flexible tube 10, at the boundary between the shaft 14 and the bag 15, the portion located on the outer periphery of the flexible tube 10 in a side sectional view has the same thickness as the shaft 14 and the bag 15. Since the thick ribs 21 are formed so as to protrude slightly from the outer periphery of the bag body 15 and are integrally formed, they have the same strength as a corrugated pipe having a valley shape, and have a pressure resistance against water pressure flowing through the flexible pipe 10. , And a stopper is provided at the outer end of the opening 17 of the bag body 15 so that the bag body 15 can be shortened without biting. Of course, the addition of the ribs 21 does not increase the production cost.

ができる。Therefore, according to the flexible tube 10, although it has a diameter of about 75 mm to 150 mm, it can be expanded and contracted in the direction of the central axis a (extended to almost twice the length at the time of shortening). Because it exhibits a curved action consisting of a curved outer surface due to elongation and a curved inner surface due to shrinkage,
For example, it can be freely curved in an S-shape with a small radius.

長して長尺になった合成樹脂製継ぎ手を用いる。The method of using the advection tube 1 will be described. The tanks 2 and 3 having the tank-attached sockets 8 and 9 are installed at predetermined positions, and their level characteristics are strictly set. At this time, the interval between the tube ends of the tank-equipped sockets 8 and 9 is, for example, 450 mm.
In other words, if the interval is narrow, the sockets 8 and 9 are connected to each other by using the slightly longer advection tube 1 in a state extended from the tube end interval. That is, a synthetic resin joint that is longer than the pipe end interval is used.

The flexible tube 10 is shortened for simple joining.

Since sufficient space is available for the work, the arbitration work of the connection can be easily performed. Of course, it is also possible to easily perform a rubber ring joint filing operation.

When connecting the pipes, sliding the pipe joint around the outer circumference of the new pipe, or sliding the end of the new pipe inside the pipe joint to connect the old and new ends is called a "Yaritori function") and an S-shaped curve.
