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 and a drainage vertical pipe cleaning method 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 2 is advanced in the drainage vertical pipe H from the upper 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 2 is advanced in the drainage vertical pipe H from the higher 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 higher 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 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 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 drainage vertical pipe H is advanced 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. Then, it falls downward in the drainage vertical pipe H. 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.

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 this embodiment, first, the drainage vertical pipe cleaning device 20 is installed. Specifically, the drainage vertical pipe cleaning device 20 is disposed around the drainage vertical pipe L to be cleaned in a high-rise building. Then, the drainage vertical pipe L is cut on the lower floor, preferably 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. At this time, the high-pressure water ejection nozzle 2 and the camera 5 attached to the tip of the pressure hose 1 are allowed to enter the root of the drainage vertical pipe L.

Thus, in the drainage vertical pipe L, they are fed from the lower floor side toward the upper floor side. From the hose reel 13, the pressure-resistant hose 1, the rectilinear support material 4, and the cable 5 a of the camera 5 that are bundled with the cladding tube 6 are sequentially fed out.

  At this time, when sending out the pressure hose 1 bundled with the cladding tube 6, the rectilinear support material 4, and the cable 5 a of the camera 5, high pressure water is sent from the high pressure water washing machine 3, thereby high pressure from the high pressure water jet nozzle 2. Spray water. 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 a propulsive force in the traveling direction by reverse injection is generated, it is easy to send from the lower floor side to the upper floor side.

  Then, as shown in FIG. 7, in the drainage vertical pipe L from the first floor (1F), 2F, 3F,... And feed it from the lower floor to the upper floor. In the drainage vertical pipe cleaning device 20, the pressure-resistant hose 1 is supported by the rectilinear support material 4. Therefore, the pressure hose 1 can be easily sent from the lower floor side to the upper floor side while maintaining the upright posture without bending the pressure hose 1.

  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 jet nozzle 2 cleans the drainage vertical pipe L from the lower floor side to the upper floor side while being sent from the lower floor side to the upper 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 upper floor side, so that the falling sludge S is dammed by the sludge S to which the falling sludge adheres, and the portion is blocked. No problems arise.

  As shown in FIG. 7, a camera 5 is provided near the high-pressure water ejection nozzle 2 to capture a video or image near the high-pressure water ejection nozzle 2. Images and images taken by the camera 5 are displayed on the monitor 11 connected via the cable 5a. 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.

  The drainage vertical pipe cleaning apparatus and drainage vertical pipe cleaning method using the drainage vertical pipe cleaning method according to the present invention is 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 reduced. The vertical tube can be cleaned efficiently.
