Description

  The present invention relates to a cleaning mobile body, and more particularly to a cleaning mobile body that removes deposits attached to an inner wall of a pipe line to be cleaned.

  Pipe lines are used in various forms in various places. For example, there are water and sewer pipes, pipes for sending raw materials and fuels in factories, drain pipes in the home, and the like. There are various forms such as gas, liquid, and solid for an object flowing through a pipeline.

  A sewer pipe will be described as an example. The sewer is a collection of facilities and equipment for collecting rainwater and sewage (sewage) in urban areas mainly in underground waterways, etc., and then discharging them into public water areas. The sewage and sewage (sewage) are purified. Water treatment such as is performed. There is a sewer pipe as a representative of the underground waterway.

  There is precipitation in meteorology as rainwater flowing through sewer pipes. It also includes snowmelt water that has melted due to rising temperatures. Examples of sewage flowing through sewer pipes include human waste from flush toilets at home, domestic wastewater generated by cooking and washing at home, and industrial wastewater from shops and factories. Therefore, the sewage composed of these rainwater and sewage contains a large amount of dust that easily accumulates in the sewer pipe, and dirt that easily adheres to the pipe wall of the sewer pipe.

  As described above, sewage such as domestic wastewater and industrial wastewater flows into the sewer pipe, so that a large amount of sediment (scale) easily adheres to the inside of the pipe, and dust, filth and the like remain. If this happens, the flow capacity of the pipe will decrease and the pipe may become clogged. Therefore, it is necessary to periodically inspect and clean sewer pipes so that problems such as clogging do not occur.

  Conventionally, as a method for cleaning a sewer pipe, there has been a solid pig method (for example, Patent Document 1) and a nozzle method (for example, Patent Document 2). In the pig method, a solid bullet-shaped pig (moving body in the pipe) is fed into the main pipe and moved while bringing the outer peripheral surface of the pig into contact with the inner wall surface of the pipe by pressure feeding or suction, thereby removing the scale. is there. On the other hand, with the nozzle method, the nozzle is fixedly attached to the insertion tip of the hose, and the scale attached to and deposited on the inner wall surface of the pipe is removed by injecting high-pressure water from the nozzle while the hose is inserted into the pipe. To do.

Japanese Patent Laid-Open No. 2001-191045 Japanese Patent Laid-Open No. 9-10716

  In the pig method of Patent Document 1, since the diameter of the pig is 50 to 90% of the diameter of the pipe to be cleaned, a gap is generated between the inner diameter of the pipe and the pig, and small deposits cannot be removed and remain. There is a problem of doing. The nozzle method of Patent Document 2 removes deposits by jetting high-pressure water, but there is a problem that water pressure and the amount of water are limited and cleaning cannot be performed sufficiently. That is, in the pig method and the nozzle method, it is possible to remove relatively large deposits deposited on the inner wall, but it is not possible to completely remove minute deposits attached to the inner wall.

  This invention is made | formed in view of the said subject, The objective is to provide the mobile body for cleaning which can clean the deposit | attachment of the inner wall of a pipe line reliably.

In order to achieve the above object, the cleaning moving body according to claim 1 is introduced into the pipe , and a sherbet-like fluid having ice particles and water from behind in the section to be cleaned of the pipe. and further meet cleaning mobile to clean the cleaning target section by being moved while in contact with the tube passage surface by pressure injecting water from behind, of the body portion and the body portion A rib-like protrusion formed on the outer surface, and the main body and the protrusion are integrally formed of an elastic body, and have a size capable of easily closing the inside of the pipe as a whole, The rib-like protrusions are characterized in that the extending direction is oblique to the moving direction.

  With this configuration, the cleaning moving body can be moved while being in contact with the inner surface of the pipeline, but the rib-like protrusion is provided on the surface of the main body, and the extending direction is the moving direction of the cleaning moving body. Therefore, when the cleaning moving body is moved, a force for rotating the main body portion in the circumferential direction is generated by friction between the rib-like protrusion and the inner wall of the pipe. Therefore, since the cleaning moving body moves with rotation, the cleaning operation in the circumferential direction along the inner wall of the pipeline is performed in addition to the cleaning operation in the traveling direction, so that the inner wall of the pipeline can be effectively cleaned. It is.

Elastic bodies, for example, rubber, a suitable polyurethane foams, it is possible to easily form a rib-like projections on the outer surface.
As a result, when moving by being pushed forward by the sherbet-like fluid and water that is pressurized and injected from behind, the fluid moves in contact with the inside of the pipeline while being elastically deformed. That is, in combination with the precondition that it is pushed from behind by a sherbet-like fluid and water, a specific cleaning effect is produced. In particular, the cleaning moving body is sized to easily close the inside of the pipe, but the rib-like projections are formed, and the force to move from the rear is effective because it is a sherbet-like fluid. Will be added.
More specifically, since the cleaning moving body is placed in a state where pressure is applied from the rear, the cleaning moving body secures a wider contact surface with respect to the inner wall of the pipe line. Therefore, an appropriate pressing force is applied to the cleaning moving body, and the cleaning can be effectively performed.

In order to achieve the above object, the cleaning moving body according to claim 2 is introduced into the pipe, and a sherbet-like fluid having ice particles and water from behind in the section to be cleaned of the pipe. And a cleaning moving body for cleaning the section to be cleaned by being moved while contacting the inner surface of the pipe line by injecting water under pressure from the rear thereof. Rib-shaped projections formed on the surface, the body portion is formed by filling a fluid body in a watertight bag body, and has a size capable of easily closing the inside of the conduit, The rib-like protrusions are characterized in that the extending direction is oblique to the moving direction .

Therefore, cleaning the moving body can be configured packed fluid bag body with a watertight, diameter rotary suitable conduit to the conduit, the cleaning movement of the moving magnitude It can be easily manufactured.

The cleaning mobile body according to claim 3 is the cleaning mobile body according to claim 2 , wherein the fluid is a sherbet body having water or ice particles and water. . The sherbet body having water or ice particles and water as a fluid is harmless and easily available. Therefore, it is possible to easily and inexpensively manufacture a cleaning moving body having a size that moves while being in contact with the pipe inner surface. Moreover, since the sherbet body is used, it is possible to reduce the adhesion force by giving a temperature change to the deposit in the pipe line, and to enhance the cleaning effect.

The cleaning moving body according to claim 4 is the cleaning moving body according to claim 2 or 3 , wherein the bag body has stretchability. For example, a rubber bag is suitable. Therefore, since the bag body expands and contracts according to the amount of the fluid packed in the bag body, it is possible to easily configure a cleaning movable body having an appropriate size. Furthermore, since the bag body itself expands and contracts, the cleaning moving body can smoothly move in the pipe line even when the diameter of the pipe line changes or the pipe line is bent.

  According to the cleaning mobile body of the present invention, the cleaning mobile body can be moved while rotating while being in contact with the inner surface of the pipeline, so that the inner wall of the pipeline can be reliably cleaned. . Therefore, the quality of the cleaning operation of the pipeline is improved, and the cost of the cleaning operation can be reduced and the cleaning time can be further shortened.

  FIG. 1 is a schematic explanatory view of a cleaning moving body of the present invention. A cleaning moving body 46 shown in FIG. 1A includes a main body 62, a rib-like protrusion 64 formed on the surface thereof, and a hook 60a for moving the main body 62. The main body 62 is made of polyurethane foam, and the rib-shaped protrusion 64 and the main body 62 are integrally formed. That is, both the main body 62 and the protrusion 64 have elasticity. In addition, a hook portion 60 a for pulling the moving body 46 for cleaning from the front in the moving direction is provided. The hook portion 60 a is configured to be rotatable independently of the main body portion 62.

  The plurality of rib-shaped protrusions 64 are formed in parallel to the outer surface of the main body 62 of the cleaning moving body 46, respectively. The rib-shaped protrusion 64 has a predetermined height from the surface of the main body 62, and the extending direction forms a predetermined angle θ with the moving direction of the cleaning moving body 46. In other words, the extending direction and the moving direction of the rib-like protrusion 64 are oblique. In the present embodiment, θ is about 30 degrees. Therefore, for example, when the cleaning moving body 46 is pulled from the front in the moving direction, the cleaning moving body 46 has a rib-like shape because the rib-shaped protrusion 64 forms a predetermined angle with the moving direction. A force that rotates in the circumferential direction is generated by the friction between the protruding portion and the inner wall of the pipe line, and the cleaning moving body 46 moves while rotating.

  When the cleaning moving body 46 moves while rotating in the pipeline 12, a cleaning operation by rotation is added in addition to the cleaning operation by the movement of the cleaning moving body 46, and deposits and the like in the pipeline 12 are reliably removed. It is possible.

  As will be described later, the cleaning moving body 46 can clean the pipe line 12 by attaching a string-like body or the like to the hook portion 60a, performing a pulling operation from the front in the moving direction, and rotating it. Further, as will be described later, it is possible to push away with a sherbet-like fluid having water and ice particles.

  FIGS. 1B to 1D are schematic explanatory views showing a cross section of the rib-shaped protrusion 64. As the cross-sectional shape, a rectangle (a), a semicircle (c), and a concave portion (d) provided on the upper side of the rectangle are shown as an example. The rib-like protrusion 64 can have a height, a cross-sectional shape, and the like appropriately determined depending on the diameter of the pipeline, the amount of deposits, and the like.

  FIG. 2A shows a state of being introduced into the conduit 12. Further, the cleaning moving body 46 is shown being moved by the string-like body 39 from the front in the moving direction. FIG. 2B shows a state in which two cleaning moving bodies 46 are subordinately connected as the cleaning moving body 50. The two cleaning moving bodies 46 can rotate independently of each other. Further, the angles θ formed by the moving directions in the extending direction of the rib-like protrusions 64 of the two cleaning moving bodies 46 are +30 degrees and −30 degrees, respectively. That is, the extending direction of the rib-like protrusion 64 is obliquely counterclockwise and clockwise with respect to the moving direction. Therefore, when the two cleaning moving bodies 46 are moved, they move in the pipeline 12 while rotating in opposite directions. Since the rotations are in opposite directions, the inner wall in the pipe line 12 is more reliably cleaned.

  The cleaning moving body described above is an example, and various other configurations are conceivable. For example, it is possible to configure the main body using rubber reinforced with fibers or the like. Furthermore, the structure which packed the fluid as a filler in the stretchable and watertight bag body may be sufficient. The filler may be a porous elastic member impregnated with a fluid. In addition, the rib-like protrusions 64 have a predetermined angle in the moving direction and continuously extend along the outer surface of the main body 62, but may extend intermittently. Furthermore, it may be formed by meandering in the extending direction. These are determined in consideration of the ease of rotational movement and the like.

(First embodiment)
FIG. 3 is a schematic explanatory view according to the first embodiment for cleaning a pipeline using the cleaning moving body of the present invention. The pipe line to be cleaned is the sewer pipe 12, and this sewer pipe 12 is buried at a predetermined depth from the ground. Further, the sewer pipe 12 has manholes embedded therein at predetermined intervals, and two manholes 16 and 18 are shown in FIG. The left manhole 16 is the upstream manhole 16 and the right manhole 18 is the downstream manhole 18. The sewage 20 usually flows through the manhole 16, the sewer pipe 12, and the manhole 18. The sewer pipe 12 is exaggerated.

  In FIG. 3, a section between two manholes 16 and 18 is a section 14 to be cleaned of the pipe line 12. The sewage 20 flows from the left side to the right side in FIG. 3, but during the cleaning operation, the sewage 20 is pumped from the upstream manhole 16 to the downstream manhole 18 by a sewage drain pipe and drain pump (not shown). It may be allowed to flow around the section 14.

  Before starting the cleaning work, perform the following setup work. A cleaning moving body 54 is introduced upstream of the cleaning target section 14. This introduction work can be performed in the upstream manhole 16. On the other hand, a discharge communication pipe 24 is attached in the manhole 18 on the downstream side. Further, the lid portion 17 is attached to the opening end portion of the pipe line 12 that is not the cleaning target section in the downstream side manhole 18. The lid portion 17 is provided with an opening / closing portion 17a. Until the cleaning movable body 54 pushes out the dust 42 and the deposit 43 into the downstream manhole 18 after the cleaning is started, the opening / closing portion 17a is not Opened. Thereafter, the opening / closing part 17 a is closed, and the dust 42 pushed out by the cleaning moving body 54, the scraped deposits 43, and the like are collected through the discharge communication pipe 22.

  The cleaning moving body 46 is the same as that shown in FIG. 1A, but the main body portion is provided with hook portions 60a at two positions on the front and rear sides so that it can be pulled from the front direction and the rear direction. It has been. The hook portions 60a are connected to the string-like bodies 39, respectively. Since the hook portions 60a can be rotated independently of the main body portion 62 as described above, the string-like bodies 39 are rotated by the rotation of the cleaning moving body 46. Tangles and the like are prevented.

  The string-like body 39 is connected to a winding device 49 that pulls out or sends out the string-like body 39. The winding devices 49 are installed in the vicinity of the opening of the upstream manhole 16 and in the vicinity of the opening of the downstream manhole 18, respectively. The winding device 49 allows the cleaning moving body 46 to move in one direction in the cleaning target section 14 or to reciprocate. Note that reels 33 are provided everywhere to enable the string-like body 39 to be smoothly taken out or sent out. In addition, although it is necessary to convey the front-end | tip of the string-like body 39 attached ahead of the moving direction of the cleaning mobile body 46 to the downstream side manhole 18, this is possible by a normal method. For example, it is possible to tie the tip of the string-like body 39 to the tip of a long wire and extend the wire from the upstream manhole 16 to the downstream manhole 18.

  In the present embodiment, the cleaning of the cleaning target section 14 is performed by introducing the cleaning moving body 46 into the pipe line 12 and securing the simple blockage state between the pipe line 12 and the cleaning moving body 46 and then moving the cleaning object. This was done by reciprocating the body 46 along the conduit 12 in the section 14 to be cleaned. This reciprocation was performed as follows, for example. The string-like body 39 is pulled by the winding device 49 installed on the downstream side manhole 18 side to move the cleaning moving body 46 to the downstream side by about 2 m. At this time, the winding device 49 installed on the upstream manhole side is in a state where the string-like body 39 can be sent out freely. After moving the cleaning body 46 about 2 m along the pipe line 12 to the downstream side, the string-like body 39 is pulled (retracted) by the winding device 48 installed on the upstream side manhole 18 side, and cleaned. The moving body 46 is pulled back about 2 m upstream. At this time, the winding device 49 installed on the downstream side manhole 18 side is in a state where the string-like body 39 can be sent out freely.

  After the cleaning moving body 46 is reciprocated by about 2 m within the cleaning target section 14, the cleaning moving body 46 is moved about 4m downstream, and then moved about 2m upstream (pulled back) in the same manner as described above. . In this manner, the reciprocation of about 2 m is repeated, and the cleaning is finished when the cleaning moving body 46 reaches the downstream manhole 18. The dust 42 and scraped deposits 43 in the extruded pipe line 12 are collected in the downstream manhole 18, sucked by the suction pump 36 through the discharge communication pipe 24, and collected in the discharge tank 40. The

  According to the present embodiment, the cleaning moving body 46 having the rib-like protrusions 64 formed on the surface moves while rotating in the cleaning target section 14 while maintaining a contact state with the pipe line. By rotating and moving the cleaning moving body, the cleaning operation by the rotation is performed in addition to the cleaning operation by the movement of the rib-like protrusion 64, and the inside of the pipe line 12 can be effectively cleaned. Furthermore, the reciprocating movement causes the rotation of the cleaning moving body to be reversed between the pulling operation (forward path) and the pulling back operation (return path), so that the inner wall of the conduit 12 is rubbed more effectively and more reliably. It can be cleaned.

(Second Embodiment)
Next, FIG. 4 is a schematic explanatory view according to a second embodiment for cleaning a pipeline using the cleaning moving body of the present invention. The difference from the first embodiment is that two cleaning mobile bodies 46 are connected in series to form the cleaning mobile body 50. The moving body for cleaning 50 is the same as that shown in FIG. 2B, but the front and rear of the moving body for cleaning 50 so that the pulling operation can be performed from the front side and the rear side of the moving body for cleaning 50. A hook portion 60a is provided. As described above, each main body 62 of the cleaning moving body 50 can rotate independently, and the hook 60a and the main body 62 can also rotate independently.

  In the present embodiment, when the cleaning moving body 50 is pulled, the two main body parts 62 move while rotating, but the rotation directions are different. When the cleaning moving body 50 is pulled back, it moves while rotating in the same manner, but the direction of rotation is different from that during the pulling operation.

  In the present embodiment, since there are two cleaning moving bodies as compared with the first embodiment, the cleaning effect is improved more reliably than one. Further, by reciprocating, the inner wall of the pipe line 12 is rubbed in the left and right rotations by the front cleaning moving body, and is rubbed in the right and left directions by the rear cleaning moving body. Thus, the cleaning operation by quadruple rotation is performed by reciprocating. The traction force for pulling the cleaning moving body 50 is required to be approximately twice that of the case of one cleaning moving body, but more reliable cleaning of the inside of the pipe line is performed.

(Third embodiment)
FIG. 5 is a schematic explanatory view according to a third embodiment of cleaning a pipeline using the cleaning moving body of the present invention. The difference from the first embodiment and the second embodiment is that the cleaning moving body 46 is introduced into the pipe 12 and then has a sherbet shape having ice particles and water behind the cleaning moving body 46. The fluid 48 is filled with a predetermined amount, and water 50 is injected under pressure from the rear of the fluid 48 to move the cleaning moving body 46. Since the fluid 48 has a cleaning action, the cleaning and cleaning are simultaneously performed by the cleaning moving body 46 and the fluid 48, as will be described later. The ratio of ice particles to water in the fluid 48 used is 7 to 9 to 3 to 1. That is, most are ice particles. The fluid 48 is appropriately added with salt, and the amount thereof is about 3 to 7% by mass.

  As a setup before the cleaning work, after the cleaning moving body 46 is introduced to the upstream side of the cleaning target section 14, the cleaning moving body 46 is introduced into the opening end portion of the pipe line 12 of the cleaning target section 14 on the side where the introducing cleaning moving body 46 is introduced. A sealing lid 15 is installed. The lid portion 15 may be made of any material such as metal or plastic, and prevents the water injected under pressure from the cleaning target section 14 from leaking out. The lid 15 may be fixed using a reaction force support material or the like (not shown). An infusion communication tube 22 is attached to the lid portion 15 in a state where the inside of the cleaning target section 14 communicates with the outside. On the other hand, in the downstream manhole 18, as described in the first embodiment, the discharge communication pipe 24 is attached, and further, the pipe line 12 that is not the cleaning target section 14 in the downstream manhole 18. A lid 17 is attached to the open end.

  A fluid injection means 28 and a liquid injection means 30 are connected to the injection communication pipe 22 as an injection device 31. The fluid injection means 28 and the liquid injection means 30 are switched by the control means 34 between a sherbet-like fluid 48 having water and ice particles from the fluid injection means 28 and water 50 from the liquid injection means 30. Then, the air is continuously injected into the injecting communication pipe 22 so that no air is mixed therein. The control means 34 is provided with a switching valve (not shown) and a control device (not shown) for changing the injection amount in order to enable the above-described operation. The liquid injecting means 30 is specifically a tank car or the like filled with water 50, and is provided with a water pump or the like (not shown). It is possible to change the injection pressure of the water 50 into the cleaning target section 14 by adjusting the water supply amount of the water pump.

  The fluid injection means 28 is a tank car or the like that is specifically loaded with a sherbet-like fluid 48 having water and ice particles, and is a snake pump (see FIG. 5) for injecting the fluid 48 into the section 14 to be cleaned. (Not shown). By adjusting the discharge amount of this pump, the injection pressure of the fluid 48 to the cleaning target section 14 can be changed. The movement of the cleaning moving body 46 is most preferably performed using the potential energy of the fluid 48 and the water 50 due to the height difference between the position where the pipe 12 is embedded and the ground.

  As in the first embodiment, a suction pump 36 is attached to the discharge communication pipe 24, and the dust 42 pushed out by the cleaning moving body 46, the scraped deposit 43, and the cleaning moving body 46 are stored. The fluid 48 and water 50 that have been swept away are sucked and discharged, and stored in the discharge tank 40. Note that the fluid 48 and the water 50 can also flow directly to the downstream sewer pipe by opening the opening / closing part 17a of the lid 17 depending on the degree of contamination.

  In the present embodiment, firstly, the cleaning moving body 46 moves while rotating in the pipe line 12 in the pipe line 12, so that the deposits 43 and the like on the inner wall of the pipe line 12 are scraped off. After that, the ice particles contained in the fluid 48 scrape off the strongly deposited deposit 43 and the like, and thus cleaning and washing are performed. Further, the ice particles contained in the fluid 48 have an effect of changing the temperature of the deposit 43 adhering in the pipe 12 and reducing the adhesion force of the deposit 43 to the pipe 12. The 12 cleaning is performed more effectively.

  FIG. 6 shows a procedure for starting a cleaning / cleaning operation according to the present embodiment. First, as shown in FIG. 6A, a cleaning moving body 46 suitable for cleaning the pipeline 12 is opened from the open end of the pipeline 12 on the upstream side of the cleaning target section 14 in the upstream manhole 18. Introduce. In the present embodiment, as in the first embodiment, the cleaning moving body 46 has a configuration in which a rib-like protrusion is formed on a main body made of polyurethane foam. The moving body 46 simply closes the conduit 12.

  Next, as shown in FIG. 6 (b), the lid 15 and the injection communication pipe 22 are attached to the opening end of the cleaning target section 14, and the fluid injection means 28 through the injection communication pipe 22 The fluid 48 is injected by a predetermined amount. Since the cleaning moving body 46 simply closes the section 14 to be cleaned, that is, water can ooze out but most of the fluid 48 does not pass, the fluid 48 has a large amount of flowing forward. The cleaning target section 14 can be easily filled over a predetermined length. The predetermined length is appropriately determined according to the degree of dirt in the pipe line 12 and the like because the fluid 48 cleans the inner wall of the pipe line 12 in the cleaning target section 14.

  FIG. 6 (c) shows that after the fluid 48 is filled to a predetermined length in the section 14 to be cleaned, the water 50 is injected into the liquid in order to move the cleaning moving body 46 and the fluid 48 in the pipe line 12. 30 shows the state of pressure injection. The pressurized injection of the water 50 is performed until the cleaning moving body 46 reaches the downstream manhole 18 in the cleaning target section 14. The water 50 uses tap water, but water such as sewage 20 or agricultural water can also be used. By doing so, the cost of work can be further reduced.

  When the cleaning moving body 46 introduced from the upstream manhole 16 reaches the downstream manhole 18, the cleaning moving body 46 is recovered. The recovery can be easily performed in the downstream manhole 18. Thereafter, the fluid 48 and the water 50 are sucked together with the removed dust 42 and the deposit 43 from the fluid discharge pipe 24 and collected in the drain tank 40. Note that the fluid 48 and the water 50 may flow directly downstream from the downstream manhole 18 when there is little dirt or the like.

  The diameter of the sewer pipe 12 is about 250 mm in the first to third embodiments, and the length of the sherbet-like fluid 48 having ice particles and water in the third embodiment is about 0.5. The moving speed of 3 m, sherbet-like fluid 48 or cleaning moving body 46 was 0.1 to 0.3 m / sec. Note that the moving speed can be slow immediately after the start of work and can be increased immediately before the work ends. It is also possible to move the cleaning moving body 46 using only the water 50 without using the fluid 48. However, in this case, the fluid 12 is not cleaned in the pipe 12 at the same time, but it is possible to introduce only the fluid 48 into the cleaning target section 14 later.

  According to the present embodiment, the main body made of polyurethane foam and the cleaning moving body 46 having rib-like protrusions formed on the surface thereof are moved by the sherbet-like fluid 48 having ice particles and water and the water 50. Therefore, in addition to the cleaning effect by the cleaning moving body 46, cleaning by the sherbet-like fluid 48 having ice particles and water is also performed at the same time, so that the pipe 12 is more effectively cleaned. . However, by using the cleaning moving body 54, the sherbet-like fluid 48 having ice particles and water can be effectively used without waste. Since the cleaning moving body 46 has deformability, a constant cleaning effect can always be expected even if the diameter of the pipe 12 changes or the pipe 12 is bent.

  In the first to third embodiments described above, the pipe cleaning operation by the cleaning mobile body of the present invention has been described by taking the sewer pipe 12 as an example, but the present invention is limited to these embodiments. Never happen. That is, various changes can be made without departing from the spirit of the invention. For example, a water pipe, an agricultural water pipe, various pipes in a factory, a pipe that handles food, a household drain pipe, and the like may be used as pipes to be cleaned. In addition, water (tap water) and fluid have been shown as those that sweep away the mobile body for cleaning. However, when using the liquid flowing through the pipeline to be cleaned as it is, for example, when cleaning food pipelines, etc. It is possible to use treated water or reclaimed water of sewage when using foods etc. flowing through the pipe line and cleaning the sewer pipe.
