Description

  The present invention relates to a drainage vertical pipe cleaning device for cleaning a drainage vertical pipe installed in a high-rise building such as an apartment house, a hose feed-up device for feeding a pressure hose into the drainage vertical pipe, and a drainage vertical pipe cleaning. Regarding the method.

  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. 10 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 102 is advanced in the drainage vertical pipe H 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 H. Fall downward. In the case of the method in which the high-pressure water jet nozzle 102 is advanced in the drainage vertical pipe H from the upper floor side toward the lower floor side, the sludge S grown on the lower floor side is formed in order to break down the sludge S from the upper floor side. When present, the sludge 102 that has fallen from the top accumulates on the portion and forms the closed portion A. When the closed portion A is formed, water does not escape from the drainage vertical pipe H to the lower floor side, and water flows into the side branch pipe R that leads to the drainage port B arranged in a room such as a sink, toilet, bathroom, etc. The water flowed backwards, and the water overflowed from the drain outlet B, causing 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.

  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 present invention relates to a drainage vertical pipe cleaning device, a drainage vertical pipe cleaning device, and a drainage vertical pipe that can be cleaned even in a drainage vertical pipe installed in a high-rise building, in which a large amount of sludge adheres to the inner wall and the inner diameter is small.

It is preferable that the flexible pipe which further includes a blower for blowing air toward and which houses the pressure hose is fed from the lower floor side to the higher floor side through the main path. According to such a structure, sludge and water falling in the drainage vertical pipe can be blown off from the branch pipe to the outside of the drainage vertical pipe. As a result, the problem that the vicinity of the lower floor of the drainage vertical pipe is blocked by the falling sludge is solved. Moreover, when the solid-liquid separation means connected to the branch pipe is provided, it becomes easy to treat sludge and water dropped in the drainage vertical pipe. Furthermore, the portion where the flexible tube containing the pressure-resistant hose in the branch pipe of the main path is further provided with a water stop structure prevents the falling water, broken sludge, etc. from hitting the feed roller or the like It is preferable because it can be used.

FIG. 3 is a schematic cross-sectional view of the II-II ′ cross section of FIG.

  As shown in FIGS. 2 and 3, the pressure-resistant hose 1 and the cable 5 are accommodated in a flexible tube 6 having uprightness. As shown in FIG. 3, a gap G is formed inside the flexible tube 6. As shown in FIG. 2, the distal end of the flexible tube 6 is closed with a sealing lid 14 so that the pressure-resistant hose 1 and the camera 4 are led out to the outside. Prevents sludge debris from entering.

  The flexible tube having the uprightness in the present embodiment is a tubular member that retains the uprightness when it is formed from a flexible shape that can be wound and a linear shape that is released from the wound state. Such a flexible tube that maintains uprightness can be transported in a state of being wound around a work site in order to have flexibility, and can be kept upright in a drainage vertical tube. Examples of such a flexible tube having an upright property include 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, and an upright flexible tube such as a flexible metal tube (pipe). .

  Specifically, the flexible tube having uprightness 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.

Moreover, the part enclosed with the broken-line circle | round | yen in FIG. 5 is explanatory drawing which shows a mode that the part which sends in the high pressure water injection hose 1 grade | etc., Is sealed with the water stop sealing material 8d. As shown in FIG. 5, the drainage vertical pipe cleaning device 20 is connected to the main path 8a, one end of which is connected to the opening on the lower floor side of the drainage vertical pipe L, the branch path 8b branched from the main path 8a, and the branch path 8b. The branch pipe 8 provided with the ventilation port 8c for ventilating toward 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. 5 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, as shown in FIG. 6, according to the method in which the high-pressure water injection hose 101 is advanced through the drainage vertical pipe H from the lower floor side to the higher floor side, the sludge S destroyed on the lower floor side is combined with the washing water W. In the drainage vertical pipe H, it falls downward. In such a case, in order to break down the sludge S from the lower floor side, the sludge S that has fallen from the top accumulates on the portion where the high-pressure water injection hose 1 in the drainage vertical pipe H is fed, and a deposition portion C is formed. There was. And when the deposition part C is formed, it becomes difficult to send in the high-pressure water injection hose 1 further. In addition, when water is not drained from the drainage vertical pipe H, there is a possibility that the 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. 5 is used to solve the above-described problem. By providing such a structure, the following effects can be obtained. That is, when high pressure water is jetted from the high pressure water jet nozzle 2 and the sludge S in the drainage vertical pipe L is destroyed, the sludge S and water W fall in the drainage vertical pipe L as shown in FIG. . At this time, it is possible to prevent the sludge S and water W that have fallen from leaking directly under the branch pipe 8 by sealing the portion into which the high-pressure water injection hose 1 is fed with the water stop sealing 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. 5, 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. 7 is an explanatory diagram 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 an opening formed in the lower floor 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. Then, the high-pressure water jet nozzle 2 and the camera 4 attached to the tip of the pressure hose 1 are inserted from the opening of the drainage vertical pipe L.

  Then, as described with reference to FIG. 4, the pressure roller hose 1 accommodated in the flexible tube 6 and the cable 5 of the camera 4 are sandwiched between the feed rollers 7 and the feed rollers 7 are rotated, thereby In the pipe L, they are fed upright from the lower floor side to the higher floor side. From the hose reel 13, the pressure hose 1 accommodated in the flexible tube 6 and the cable 5 of the camera 4 are sequentially fed out.

  At this time, when the pressure hose 1 accommodated in the flexible tube 6 and the cable 5 of the camera 4 are sent out, high pressure water is injected from the high pressure water jet nozzle 2 by sending high pressure water from the high pressure water washing machine 3. . In the case where the high pressure water jet nozzle 2 is a reverse jet nozzle that jets high pressure water in the direction opposite to the traveling direction as shown in the enlarged view of the vicinity of the high pressure water jet nozzle 2 in FIG. Since propulsive force in the traveling direction by reverse injection is generated, it becomes easy to send from the lower floor side to the higher floor side.

  Then, as shown in FIG. 7, the flexible pipe 6 that accommodates the pressure hose 1 and the cable 5 of the camera 4 in the drainage vertical pipe L is sent from the first floor (1F). After being sandwiched between the rollers 7, the flexible tube 6 is fed up from the lower floor side to the higher floor side in an upright state while forming the flexible tube 6 linearly. 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 high pressure water jet nozzle 2 in FIG. 7, the sludge S fixed to the inner wall surface of the drainage vertical pipe L is destroyed by the high pressure water W jetted from the high pressure water jet nozzle 2. The high pressure water ejection nozzle 2 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.

  As shown in FIG. 7, a camera 4 is provided near the high-pressure water jet nozzle 2 to capture a video or image near the high-pressure water jet nozzle 2. Images and images taken by the camera 4 are displayed on a monitor 11 connected via a cable 5. The operator can confirm the fixed state of the sludge S and the cleaning result in the vicinity of the portion where the high-pressure water ejection nozzle 2 has reached by looking at the video and images on the monitor 11.

  As shown in the enlarged view of the vicinity of the high pressure water jet nozzle 2 in FIG. 7, the sludge S fixed to the inner wall surface of the drainage vertical pipe L is broken by the high pressure water jet from the high pressure water jet nozzle 2 and is drained vertically. The tube L falls with the water W. As shown in FIG. 5, the falling sludge S and the water W reach the branch path 8 b by the wind from the blower 9 when reaching the branch point between the main path 8 a and the branch path 8 b of the branch pipe 8. 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.

  As mentioned above, although embodiment of the drainage vertical pipe cleaning apparatus and drainage vertical pipe cleaning method which concern on this invention was described in detail, the drainage vertical pipe cleaning apparatus and drainage vertical pipe cleaning method which concern on this invention are limited to embodiment mentioned above. The present invention is not intended to be modified and may be used as appropriate without departing from the scope of the present invention.

  For example, in the above-described embodiment, by providing the branch pipe 8, the blower 9, and the solid-liquid separation device 10, the falling sludge S and water W are blown off to the branch path 8b and sent to the solid-liquid separation device 10. Processed by solid-liquid separation. In the case where the drainage vertical pipe L is short or the diameter is large instead of such a configuration and the adverse effect due to the falling sludge S and the water W is small, as shown in FIG. 9 and the drainage vertical pipe cleaning device 30 in which the solid-liquid separation device 10 is omitted may be selected. In such a case, it is preferable because the equipment configuration can be simplified.

  For example, in the above-described embodiment, the high-pressure water ejection nozzle 2 is connected to the tip of the pressure-resistant hose 1 accommodated in the flexible tube 6 to inject high-pressure water. Instead of such a configuration, as shown in FIG. 9, the pressure hose 1 is omitted, and the high-pressure water jet nozzle 2 is directly connected to the tip of the thin upright flexible tube 16 itself. A mode in which high-pressure water is fed into 16 and high-pressure water is jetted may be selected. In such a case, the equipment configuration can be simplified, and it is preferable because it can be applied to a thin drainage vertical pipe.

  By using the drainage vertical pipe cleaning device, hose feed device and drainage vertical pipe cleaning method of the present invention, in the drainage vertical pipe installed in a high-rise building, a large amount of sludge adheres to the inner wall and the inner diameter becomes smaller. Such drainage vertical pipes can be cleaned efficiently.
