Description

  The present invention relates to a pipe cleaning nozzle device used for cleaning a drainage vertical pipe installed in a high-rise building such as an apartment house, and a drainage vertical pipe cleaning apparatus using the same.

  Drainage from facilities such as sinks, washrooms, bathrooms, and toilets in high-rise buildings such as apartment buildings passes through horizontal branch pipes that pass from the room where each facility is located, and then passes through shared drainage vertical pipes that pass through each floor. It is poured into a tank.

  The waste water contains a large amount of residue and fats and oils. On the inner wall of the drainage vertical pipe, with the passage of time through which the drainage passes, sludge (solid matter), which is a solid substance formed by agglomeration of residues and oils and fats in the drainage, gradually adheres to the pipe diameter. Decrease gradually. If the sludge is left as it is, the sludge may grow and block the drainage vertical pipe. In order to prevent such blocking of the drainage vertical pipe, the drainage vertical pipe installed in the high-rise building needs to be cleaned at regular intervals.

  As a method of cleaning the drainage vertical pipe, by inserting a pressure-resistant hose with a high-pressure water ejection nozzle at the tip into the drainage vertical pipe, and hitting the high-pressure water sprayed from the nozzle against sludge fixed to the inner wall of the drainage vertical pipe, A method of cleaning by breaking sludge (hereinafter also simply referred to as a high-pressure cleaning method) is widely used.

  The high-pressure washing method is to insert a high-pressure water ejection nozzle from the opening of the drainage vertical pipe on the higher floor, gradually draw out the pressure hose from the hose reel, and eject high-pressure water from the high-pressure water ejection nozzle to break down the sludge. A method of proceeding toward the floor and cleaning from the higher floor side to the lower floor side is widely used.

  FIG. 9 is an explanatory diagram showing a state of the method of cleaning from the higher floor side toward the lower floor side. According to the method in which the high-pressure water jet nozzle 201 is advanced in the drainage vertical pipe L from the higher floor side toward the lower floor side, the sludge S destroyed on the higher floor side is discharged along with the cleaning water W in the drainage vertical pipe L. Fall downward. In the case of the method in which the high-pressure water jet nozzle 201 is advanced in the drainage vertical pipe L from the upper floor side toward the lower floor side, the sludge S grown on the lower floor side is removed because the sludge S is destroyed from the upper floor side. When present, the sludge S that has fallen from the top accumulates on the portion and forms a closed portion A. When the closed portion A is formed, water does not escape from the drainage vertical pipe L to the lower floor side, and water flows into the side branch pipe B that leads to the drainage port R arranged in a room such as a sink, toilet, bathroom, etc. There was a case where water flowed back from the drainage port R and caused damage such as flooding the room with sewage.

  Contrary to the method described above, a method of cleaning the drainage vertical pipe from the lower floor side to the higher floor side has also been proposed. For example, the following Patent Document 1 discloses the following method. First, a method is disclosed in which a hose with a high-pressure water jet nozzle attached to the tip is inserted into the drain pipe from the building roof, lowered to the bottom of the drain pipe, and the hose is pulled up while high-pressure water is jetted from the high-pressure water jet nozzle To do.

  Moreover, the following patent document 2 lowers a hose provided with a high-pressure water jet nozzle from the roof side to the ground in a state where the high-pressure water jet nozzle is locked to the wire, and then pulls it upward with a wire. Disclosed is a cleaning method for cleaning a drain pipe by jetting high-pressure water to remove solid matter, photographing the removal status with a CCD camera, and confirming the image by the image.

  In the method of cleaning the drainage vertical pipe from the lower floor side to the higher floor side after once dropping the high pressure water jet nozzle from the higher floor side to the lower floor side as disclosed in Patent Document 1 and Patent Document 2 Had the following problems.

  As described above, ordinary high-rise buildings are cleaned at regular intervals to prevent the vertical drainage pipe from being blocked. In this way, in the case of drainage vertical pipes that have been cleaned at regular intervals and are relatively well maintained, sludge adhering to the drainage vertical pipes is removed at regular intervals. The drainage vertical pipe has an inner diameter that allows the water ejection nozzle to be lowered to the lower floor side once. However, for example, in an aged high-rise building with an age of over 30 years, the drainage vertical pipe is not cleaned every certain period due to various circumstances, and there are some buildings with insufficient maintenance. For example, for the cleaning of drainage vertical pipes, cooperation such as access to residents 'residences is indispensable. However, if residents' cooperation is not obtained, drainage vertical pipes have not been cleaned for a long time. In some cases, a large amount of sludge adhered to the inner wall. In the case of such a drainage vertical pipe left uncleaned for a long period of time, the inner diameter may become small due to sludge sticking, or an almost closed portion may be formed. In such a case, the high-pressure water jet nozzle could not be lowered from the higher floor side to the lower floor side. Therefore, the methods as disclosed in Patent Document 1 and Patent Document 2 have a large amount of sludge fixed to the inner wall of the drainage vertical pipe and the inner diameter is reduced, or a portion that is almost closed is formed. It could not be applied to cleaning the drainage vertical pipe.

  The inventor of the present invention, as described above, in a drainage vertical pipe installed in a high-rise building, a drainage vertical pipe in which a large amount of sludge is fixed to the inner wall and the inner diameter is small can be washed. A pipe cleaning device has been proposed (see Patent Document 3 and Patent Document 4 below).

  Patent Document 3 and Patent Document 4 are drainage vertical pipe cleaning devices for cleaning drainage vertical pipes of high-rise buildings, and a pressure-resistant hose having a high-pressure water jet nozzle at the tip, and a flexible holding the pressure-resistant hose upright. Disclosed is a vertical drainage cleaning device comprising an upright support material and a high-pressure water washer connected to a pressure-resistant hose and supplying high-pressure water to a tube-cleaning nozzle device.

JP 2001-342661 A JP 2002-275984 A Japanese Patent No. 5748255 Japanese Patent No. 5748251

  According to the drainage vertical pipe cleaning apparatus disclosed in Patent Document 3 and Patent Document 4, the drainage vertical pipe is moved from the lower floor side to the higher floor side only by working from the lower floor side in the drainage vertical pipe of the high-rise building. Can be washed. However, in the case where the vertical drainage pipe is washed from the lower floor side toward the higher floor side, when the high pressure water jet nozzle is advanced above the pipe, the jet water from the high pressure water jet nozzle is moved forward. If there is a clogged portion due to sludge solidified in the pipe because it does not reach sufficiently, it is not possible to send the high pressure water jet nozzle to the far end, or it is time to break down the sludge with only high pressure water It sometimes took too much.

  The present invention provides a pipe for removing sludge firmly solidified in a pipe more effectively by collapsing sludge with a rotating member in addition to cleaning the pipe of high-pressure water jetted from a high-pressure water jet nozzle. An object of the present invention is to provide a cleaning nozzle device and a drainage vertical tube cleaning device.

  One aspect of the present invention is a tube cleaning nozzle device that is connected to the tip of a pressure-resistant hose that supplies high-pressure water, and removes sludge adhering to the inner wall of the tube while traveling through the tube by injecting high-pressure water. A high-pressure water jet nozzle that jets high-pressure water supplied via a pressure-resistant hose to the rear in the axial direction, and a rotating scraper that is disposed in front of the high-pressure water jet nozzle in the axial direction and has a rotation axis in the axial direction. A tube cleaning nozzle device comprising a member and a drive member that rotates a scraper member.

  According to the pipe cleaning nozzle device of the present invention, in addition to cleaning the pipe with the high-pressure water ejected from the high-pressure water ejection nozzle, the sludge collapsed by the rotating member, thereby further solidifying the sludge solidified in the pipe. It can be effectively removed. Further, according to the drainage vertical pipe cleaning device of the present invention, in the drainage vertical pipe installed in a high-rise building, even a drainage vertical pipe where a large amount of sludge adheres to the inner wall and the inner diameter becomes small is effective. Can be washed.

[First Embodiment]
1A and 1B are schematic views for explaining the overall configuration of a tube cleaning nozzle device 100 according to an embodiment of the present invention. FIG. 1A is a front view and FIG. 1B is a schematic view showing a cross-sectional structure. In FIG. 1, 101 is a high-pressure water jet nozzle provided with a nozzle head 101a having an injection port h and a shaft body 101b, 102 is a rotating bead-shaped scraper member, 103 is a motor for rotating the scraper member, and 104 is high-pressure water. A cylindrical housing 105 that houses the ejection nozzle 100 in the axial direction, and 105 is a sled guide member. The motor 103 is connected to wirings 103a and 103b to which power is supplied from a power source (not shown). In addition, the cylindrical housing 104 is formed with an opening 104a that ensures ejection of high-pressure water ejected from the ejection port h. The high-pressure water jet nozzle 101 is connected to the pressure-resistant hose 1 through a pressure-resistant joint (not shown), and high-pressure water is supplied from a high-pressure water washing machine that supplies high-pressure water described later.

  The nozzle device for pipe cleaning 100 is for removing sludge adhering to the inner wall of the pipe while advancing in the drain pipe by injecting high-pressure water connected to the tip of the pressure hose 1 for supplying high-pressure water. Device. The nozzle head 101a of the high-pressure water ejection nozzle 101 is connected to be rotatable about the axial direction A of the shaft body 101b, and the high-pressure water supplied via the pressure hose 1 is passed from the injection port h to the rear in the axial direction A, Preferably, high-pressure water is jetted while rotating by jetting obliquely backward. In the pipe, high-pressure water is jetted onto the inner wall of the pipe, so that sludge and the like adhering to the inner wall of the pipe are peeled off.

  The bead-like scraper member 102 is a member formed by connecting hard spheres such as metals and ceramics in a linear manner in a bead shape and having one end coupled to the outer periphery of a columnar or cylindrical support material. The rotating shaft 102 a of the rotating beaded scraper member 102 is connected to the shaft 103 c of the motor 103. Further, the motor 103 is driven to rotate the shaft 103c by being energized from a power source (not shown) via the wirings 103a and 103b. The beaded scraper member 102 connected to the shaft 103c rotates at a high speed. In the pipe, the bead-like scraper member 102 rotates at a high speed around the rotation shaft 102a, and is struck by sludge attached to the inner wall of the pipe, particularly sludge fixed to the tip in the traveling direction, to collapse the sludge. In particular, the bead-like scraper member 102 is mechanically impacted on sludge that has become harder to be destroyed by high-pressure water injection by being hit against the sludge while acting like a whip by centrifugal force generated by the rotation of the motor 103. Can be broken.

  In addition, the scraper member in the present invention is a metal or ceramic hard member that breaks sludge due to the effects of scraping, grinding, polishing, grinding, etc. by contacting the sludge while rotating.

  In the tube cleaning nozzle device 100, the high-pressure water ejection nozzle 101 is accommodated in the cylindrical housing 104 while being arranged in the axial direction. The cylindrical housing 104 is a support member that accommodates the high-pressure water ejection nozzle 101 and is disposed and fixed in the axial direction A with the motor 103 and the scraper member 102. The tube cleaning nozzle device 100 is also a support member for fixing at least one sled guide member 105 to the outer peripheral surface of the cylindrical housing 104.

  When the drainage vertical pipe is cleaned, the sled guide member 105 widens the diameter in the direction perpendicular to the axial direction A of the pipe cleaning nozzle device 100 inside the drainage vertical pipe, thereby increasing the pressure inside the drainage vertical pipe. The nozzle device for pipe cleaning is prevented from violating in the drainage vertical pipe due to the impact of water jet. Moreover, by being formed in the shape of a warp, it is possible to avoid getting caught in the opening of the horizontal pipe branched from the vertical drainage pipe, and to assist the nozzle device 100 for pipe cleaning in a straight line.

  FIG. 2 is a schematic front view showing a configuration of a tube cleaning nozzle device 110 according to a modification of the tube cleaning nozzle device 100 of FIG. The tube cleaning nozzle device 110 has a configuration in which a columnar block-shaped rotating member 112 having a blade or teeth for grinding is mounted instead of the beaded scraper member 102 of the tube cleaning nozzle device 100. The rotating shaft of the block-like rotating member 112 having blades or teeth is connected to the shaft 103 a of the motor 103. Then, when the motor 103 is energized from the power supply (not shown) via the wirings 103a and 103b, the block-like rotating member 112 having a blade or teeth for grinding connected to the shaft 103a rotates. In the pipe, the block-like rotating member 112 having a grinding blade rotates at a high speed around the rotating shaft 102a, thereby contacting sludge adhering to the inner wall of the pipe, particularly sludge adhering to the tip in the traveling direction. Grind and collapse. By mounting the block-shaped rotating member provided with such a grinding blade, it is possible to grind and break up the enlarged sludge that is difficult to break by high-pressure water injection.

  In FIG. 3, reference numeral 203 denotes a water wheel that rotates the scraper member 102. The water wheel 203 is rotatably housed in a closed branch member 205 with the shaft 203a led out to the outside. The sealed branch member 205 is connected to the high-pressure water supply path 204a and the high-pressure water drainage path 204b.

  The pressure hose 1 is connected to a high-pressure water washing machine that supplies high-pressure water described later. The pressure hose 1 is connected to the high-pressure water supply path 204a, and allows the high-pressure water to pass through the high-pressure water supply path 204a. Then, the high-pressure water is sent to the hermetic branch member 205 connected to the high-pressure water supply path 204a, so that the water wheel 203 rotates at high speed around the axial direction A. And the bead-like scraper member 102 connected to the shaft 203a of the water wheel 203 rotates. The high-pressure water sent from the high-pressure water supply channel 204 a to the sealed branch member 205 passes through the sealed branch member 205 and is sent to the high-pressure water drainage channel 204 b connected to the sealed branch member 205.

  The high-pressure water drainage channel 204 b is connected to the high-pressure water ejection nozzle 101. The high pressure water jet nozzle 101 is supplied with high pressure water that has passed through the high pressure water drainage channel 204b. Then, the high-pressure water that has passed through the high-pressure water drainage channel 204b is jetted from the nozzle h of the nozzle head 101a of the high-pressure water jet nozzle 101 to the rear in the axial direction A, preferably obliquely rearward, so that the high-pressure water is jetted while rotating. To do. In the pipe, high-pressure water is jetted onto the inner wall of the pipe, so that sludge and the like adhering to the inner wall of the pipe are peeled off.

  According to such a nozzle cleaning nozzle device 200, the bead-like scraper member 102 rotates at high speed around the rotation shaft 102a in the pipe, and thereby adheres to sludge adhering to the inner wall of the pipe, particularly the tip in the traveling direction. The sludge is smashed by the sludge. In addition, the high-pressure water sprayed from the injection port 101a of the high-pressure water ejection nozzle 101 causes the sludge and the like attached to the inner wall of the pipe to be peeled off by ejecting the high-pressure water onto the inner wall of the pipe in the drainage vertical pipe.

  In the pipe cleaning nozzle device 200 of the second embodiment, a water wheel 203 for rotating the scraper member 102 is disposed in a path for supplying high pressure water to the high pressure water jet nozzle 101, and the scraper member 102 is driven by rotation of the water wheel. Rotate. In the tube cleaning nozzle device 100 according to the first embodiment, the scraper member 102 is rotated by the motor 103. However, if the scraper member 102 is rotated by the motor 103, the motor may be burned and damaged. It is necessary to take measures such as replacing the motor. The tube cleaning nozzle device 200 according to the second embodiment is excellent in durability because the scraper member 102 is driven to rotate by the water wheel 203 so that no seizure or the like occurs.

It is the schematic cross section which looked at the front-end | tip vicinity of a state in the longitudinal direction.

  As shown in FIG. 5, the pressure hose 1 and the wirings 103 a and 103 b are accommodated in a flexible upright support material 6. The flexible upright support material 6 in this embodiment is tubular. As shown in FIG. 5, the end of the flexible upright support member 6 is closed with a sealing lid 14 so that the pressure-resistant hose 1 and the wirings 103a and 103b are led out to the outside. This prevents water and broken sludge fragments from entering the material 6.

  The flexible upright support material is a linear or tubular member that retains uprightness when it is linearly shaped after being released from the wound state and flexible. Such a flexible upright support material can be transported in a wound state to the work site in order to have flexibility, and can maintain uprightness in the drainage vertical pipe.

  As a tubular flexible upright support material, for example, an aluminum three-layer tube in which an inner layer and an outer layer of an aluminum tube are coated with a resin such as polyethylene, an upright flexible tube such as a flexible metal tube (pipe), etc., Examples include a flexible member that can be wound and a tubular member that has straightness when released from a wound state. Moreover, as a linear rectilinear support material, for example, an elastic rod that is widely used as an incoming rod for wiring of a building is particularly preferably used. As a specific example of such an elastic rod, for example, a fiber reinforced plastic reinforced with glass fiber, carbon fiber, steel fiber, ceramic fiber or the like is mainly used, and has a diameter of about 1 to 15 mm, further about 3 to 10 mm. Such a rod is preferably used. Examples of such commercially available elastic rods include Marvel Super Yellow and Super Snake.

  Specifically, the flexible upright support member preferably has a rigidity capable of maintaining an upright posture of, for example, at least 1 m, preferably 2 m, more preferably 3 m, and particularly preferably 5 m when standing upright. By accommodating the pressure hose in such a flexible upright support material, the pressure hose can be kept upright in the vertical drainage pipe, and the tube cleaning nozzle device provided at the tip is sent to a higher floor. Can be raised.

  FIG. 6 is a schematic diagram showing an enlarged partial configuration of the drainage vertical pipe cleaning device 20 in the vicinity of the feed roller 7 that feeds up the tubular flexible upright support material 6 that houses the pressure-resistant hose 1 and the wires 103a and 103b. FIG. As shown in FIG. 6, the drainage vertical pipe cleaning device 20 is provided with four sets of feed rollers 7. The rollers forming each pair of the feed rollers 7 are clockwise one and the other counterclockwise so that the pressure hose 1 and the wirings 103a and 103b accommodated in the flexible upright support 6 are sent upward. It is rotating. The feed roller 7 is disposed below the opening formed in the drainage vertical pipe L in advance, and has a tubular shape that accommodates the pressure-resistant hose 1 and the wirings 103a and 103b from the opening on the lower floor side toward the higher floor side. The flexible upright support material 6 is fed up while being pinched. The drive mechanism of the feed roller 7 is not particularly limited. For example, a driving force may be supplied such as a winding gear mechanism having a handle for applying a driving force to the feed roller 7 and a rotating force by a person turning the handle, or an electric motor. There is no particular limitation.

  FIG. 7 is a schematic explanatory view showing an enlarged partial configuration in the vicinity of the branch pipe 8, the blower 9, and the solid-liquid separator 10 of the drainage vertical pipe cleaning device 20. Moreover, the part enclosed with the broken-line circle | round | yen in FIG. 7 is explanatory drawing which shows a mode that the part which sends in the nozzle apparatus 100 for pipe washing is sealed with the water stop sealing material 8d. As shown in FIG. 7, the drainage vertical pipe cleaning device 10 has a main path 8a connected at one end to the drainage vertical pipe L, a branch path 8b branched from the main path 8a, and an air flow for blowing air toward the branch path 8b. A branch pipe 8 having a port 8c is arranged. A blower 9 for blowing air toward the branch path 8b is connected to the air outlet 8c of the branch pipe 8. Further, a solid-liquid separation device 10 including a net 10a and a drainage pump 10b is connected to the branch path 8b of the branch pipe 8. The structure shown in FIG. 7 is arbitrarily provided in order to solve the problems that occur when cleaning from the lower floor side to the higher floor side as described below.

  For example, according to the method of moving the drainage vertical pipe through the nozzle cleaning nozzle device from the lower floor side to the higher floor side, the sludge destroyed on the lower floor side falls downward in the drainage vertical pipe L together with the cleaning water. To do. In such a case, in order to break down the sludge from the lower floor side, the sludge that has fallen from the top sometimes accumulates in the portion where the pipe cleaning nozzle device in the drainage vertical pipe L is fed. When sludge accumulates, it becomes difficult to further feed the tube cleaning nozzle device. In addition, when water is not drained from the drainage vertical pipe L, there is a risk that water will overflow from the piping in the room by flowing back to the horizontal branch pipe that leads to the room where the facilities on the lower floors are arranged.

  The structure shown in FIG. 7 is used to solve the above-described problem. By providing such a structure, the following effects can be obtained. That is, when the pipe cleaning nozzle device 100 destroys the sludge S in the drainage vertical pipe L, the sludge S and the water W fall in the drainage vertical pipe L. At this time, it is possible to suppress the sludge S and the water W that have fallen from leaking directly under the branch pipe 8 by sealing the portion into which the pipe cleaning nozzle device 100 is fed by the water stop seal material 8d. Further, by using the blower 9 to create a flow of wind from the air outlet 8c of the branch pipe 8 toward the branch path 8b, the sludge S and water W that have fallen are blown off to the branch pipe 8 side. Accordingly, the sludge S and the water W can be discharged from the inside of the drainage vertical pipe L to the outside.

  Moreover, in the structure as shown in FIG. 7, the solid-liquid separator 10 provided with the net | network 10a and the drainage pump 10b is connected to the end of the branch path 8b. By disposing such a solid-liquid separator 10, the sludge S discharged from the branch path 8b and the water W can be separated. And the water W isolate | separated with the solid-liquid separator 10 can be discharged | emitted to the existing drainage vertical pipe, the drainage horizontal pipe 12, etc. as it is. Moreover, the sludge S separated by the solid-liquid separator 10 can be easily treated as industrial waste after being collected.

  Next, an embodiment of a drainage vertical pipe cleaning method using the drainage vertical pipe cleaning apparatus 20 as described above will be described with reference to the drawings.

  FIG. 8 is an explanatory view for explaining an embodiment of the drainage vertical pipe cleaning method according to the present invention. In the drainage vertical pipe cleaning method of the present embodiment, first, the drainage vertical pipe cleaning device 20 is connected to the opening of the drainage vertical pipe L. Specifically, the drainage vertical pipe L is cut on the lower floor of the drainage vertical pipe, preferably on the first floor. And the opening part formed by the cutting | disconnection of the drainage vertical pipe L and the branch pipe 8 of the drainage vertical pipe cleaning apparatus 20 are connected using a coupling joint 8e etc. And the nozzle apparatus 100 for pipe washing | cleaning with which the front-end | tip of the pressure | voltage resistant hose 1 was mounted | worn is penetrated from the opening part of the drainage vertical pipe L. FIG.

  Then, as described with reference to FIG. 6, the pressure roller hose 1 accommodated in the flexible upright support material 6 is sandwiched between the feed rollers 7, and the feed rollers 7 are rotated. , Feed them from the lower floor side toward the higher floor side. From the hose reel 13, the pressure hose 1 and the wirings 103a and 103b accommodated in the flexible upright support material 6 are sequentially drawn out.

  At this time, when the pressure hose 1 and the wirings 103a and 103b accommodated in the flexible upright support material 6 are sent out, the high pressure water is ejected from the pipe cleaning nozzle device 100 by sending high pressure water from the high pressure water washing machine 3. High pressure water is jetted from the nozzle 101. In addition, as shown in the enlarged view of the vicinity of the tube cleaning nozzle device 100 in FIG. 8, the high-pressure water ejection nozzle 101 injects high-pressure water obliquely backward with respect to the advancing direction, thereby causing the traveling direction by reverse injection in the tube. Therefore, it becomes easy to send from the lower floor side to the higher floor side.

  Then, as shown in FIG. 8, in the drainage vertical pipe L from the first floor (1F), 2F, 3F, etc., the flexible upright support material 6 that accommodates the pressure hose 1 and the wirings 103a and 103b is provided. After being sandwiched between the feed rollers 7, the flexible upright support 6 is linearly shaped and fed up from the lower floor side to the higher floor side in an upright state. Therefore, the pressure hose 1 is sent out from the lower floor side toward the higher floor side while maintaining the upright posture without bending.

  As shown in the enlarged view of the vicinity of the pipe cleaning nozzle device 100 in FIG. 8, the sludge S fixed to the inner wall surface of the drainage vertical pipe L is a scraper member 102 and a high-pressure water jet nozzle 101 at the tip of the pipe cleaning nozzle device 100. It is destroyed by the high-pressure water W sprayed from. The pipe cleaning nozzle device 100 cleans the drainage vertical pipe L from the lower floor side to the higher floor side while being sent from the lower floor side to the higher floor side in the drainage vertical pipe L. In this way, the sludge S of the drainage vertical pipe L is crushed from the lower floor side toward the higher floor side, so that the falling sludge S is clogged by the fixed sludge S in the process of dropping, and the portion is blocked. No problems arise.

  Here, the tube cleaning nozzle device 100 is likely to be violated by the impact of jetting high-pressure water. As shown in the enlarged view of the vicinity of the pipe cleaning nozzle device 100 in FIG. 8, when the drainage vertical pipe L is connected to the branching horizontal pipe B, the pipe cleaning nozzle device 100 is exposed, and therefore the pipe cleaning nozzle The tip of the device 100 may be caught in the opening of the horizontal tube B. In such a case, the tube cleaning nozzle device 100 is provided with at least one sled guide member 105 on the outer peripheral surface of the cylindrical housing 104, so that it is caught in the opening of the horizontal tube branched from the drainage vertical tube. By avoiding this, it is possible to advance the tube cleaning nozzle device 100 linearly.

  Then, as shown in the enlarged view in the vicinity of the pipe cleaning nozzle device 100 in FIG. 8, the sludge S fixed to the inner wall surface of the drainage vertical pipe L is high-pressure water jetted from the scraper member 102 and the high-pressure water jet nozzle 101. The water drainage vertical pipe L falls along with the water W. As shown in FIG. 8, the falling sludge S and the water W reach the branch path 8b by the wind from the blower 9 when the branch point between the main path 8a and the branch path 8b of the branch pipe 8 is reached. Blown away. And the sludge S and the water W which were discharged | emitted from the branch path 8b are sent to the solid-liquid separator 10, and are processed, after carrying out solid-liquid separation.
