Description

The present invention relates to a method for cleaning a drainage pipe of a multi-layer building, in which a vertical drainage pipe having a first end connected to a sewerage hall and a second end connected to a lower end is washed with cleaning water.

A multi-story building with multiple floors has a vertical drainage pipe that runs from the top floor to the bottom floor. A horizontal conduit on each floor is connected to the vertical drain pipe, and the lower end of the vertical drain pipe is connected to the second end of the horizontal drain pipe whose first end is connected to the sewer chamber. Drainage on each floor flows from the hall to the sewer through vertical drains and horizontal drains.

Since all the drainage water from the conduits on each floor flows inside a single vertical drain pipe, the vertical wall drainage pipes are liable to be contaminated due to the attachment of the waste mixed in the drainage water. If this is left unattended, the vertical drainage pipe will be clogged, and the drainage on each floor will be hindered. Therefore, it is essential to wash the vertical drain pipes in multi-story buildings.

As a method of cleaning vertical drainage pipes in conventional multi-story buildings, a guide pipe that penetrates from the lowest floor to the uppermost floor and has outlets at multiple vertical positions is provided separately from the vertical drainage pipe. Some are installed (for example, refer to Patent Document 1). In this cleaning method, the cleaning hose is pulled up from the bottom to the top in the guide pipe to the outlets in order, and the cleaning hose is removed from the wire and pulled out into the vertical drain pipe at the floor corresponding to each outlet. The work of ejecting cleaning water from the nozzle at the tip of the hose to clean the inside of the vertical drain pipe located on the nearby floor is repeated at each outlet.

When cleaning the vertical drain pipe by ejecting the cleaning water sent from an external pump from the nozzle of the cleaning hose, the large pump must be placed on the ground, and the nozzle at the tip of the cleaning hose connected to this pump must be installed. Must move the vertical drain pipe upward from the lowest floor. Therefore, the tip of the cleaning hose is pulled up from above via the wire, but in the existing multi-layer building, there is no space for connecting the wire to the tip of the cleaning hose in the vertical drain pipe. Therefore, in the above-described conventional method for cleaning the vertical drainage pipe, the guide pipes provided with the outlets for attaching and detaching the wire at the tip of the cleaning hose at a plurality of vertical positions should be installed separately from the vertical drainage pipe. I am trying.

However, in the conventional method for cleaning the vertical drain pipe, it is necessary to install a guide pipe different from the vertical drain pipe in the building in advance, which not only causes a rise in the construction cost but also does not include the existing guide pipe. However, it is not possible to apply it to other buildings, and it is necessary to perform the work of attaching and detaching the wire to the wash hose and the work of pulling out the wash hose while interrupting the discharge of the wash water at multiple positions in the vertical direction. There is a problem that it takes time. These problems are exacerbated as the building becomes taller.

An object of the present invention is to discharge washing water from the nozzle while pulling up the wire connected to the nozzle on the meeting side of the horizontal drainage pipe where the lower end of the vertical drainage pipe is continuous, while discharging the washing water from the nozzle. An object of the present invention is to provide a method for cleaning a drainage pipe of a multi-layer building, which can easily and quickly clean a vertical drainage pipe regardless of the number of floors.

The method for cleaning a drainage pipe of a multi-layered building according to the present invention is for draining a vertical drainage pipe in which a second end of a horizontal drainage pipe whose first end is connected to a sewer chamber is connected to a lower end thereof. This is a pipe cleaning method, in which the connecting metal fitting attached to the tip of the wire is hung from the upper end to the lower end of the vertical drainage pipe, and the cleaning nozzle attached to the tip of the cleaning hose is horizontally drained from the hall. Nozzle feeding process to send to the lower end via the pipe, connecting metal drawing process to discharge the cleaning water from the cleaning nozzle to draw the connecting metal to the hall via the horizontal drain pipe, and the outside of the first end A connecting step of connecting the cleaning nozzle to the connecting fitting at the position, and a cleaning step of pulling up the wire while discharging the cleaning water from the cleaning nozzle in the vertical drain pipe are included.

The connecting metal fittings hung from the upper end to the lower end of the vertical drainage pipe in the hanging process depend on the cleaning water discharged from the cleaning nozzle fed from the hall to the lower end via the horizontal drainage pipe in the washing nozzle feeding process. In the drawing process of the connecting metal fittings, it is drawn out to the hall via the horizontal drainage pipe and connected to the washing nozzle in the connecting process. In the cleaning process, the inside of the vertical drain pipe is cleaned by discharging cleaning water from the cleaning nozzle while pulling up the wire.

In this drainage pipe cleaning method, before the connecting metal hanging process, there is a state confirmation process for confirming the state inside the vertical drainage pipe, and the cleaning process depends on the state inside the vertical drainage pipe confirmed in advance in the state confirmation process. It is possible to include a first adjusting step of adjusting the water pressure and the discharge amount of.

The water pressure and the discharge amount of the washing water in the washing step can be adjusted according to the state inside the vertical drain pipe confirmed in the state checking step, and the inside of the vertical drain pipe can be efficiently washed according to the state before washing.

Further, the cleaning step may include a second adjusting step of adjusting the pulling rate of the wire according to the amount of contaminants mixed in the cleaning water flowing through the horizontal drain pipe.

The wire pulling rate in the cleaning step can be adjusted according to the cleaning status during the cleaning step, and the inside of the vertical drain pipe can be efficiently cleaned according to the cleaning status.

The vertical drainage pipe of the existing building is layered by discharging the washing water from the washing nozzle while pulling up the wire connected to the washing nozzle in the vertical drainage pipe at the hall side of the horizontal drainage pipe where the lower end of the vertical drainage pipe is continuous. Regardless of the number, it can be washed easily and in a short time.

The wire 4 is fed from the winding drum 31 or wound on the winding drum 31 by the rotational force of the motor 32. The wire 4 is provided with a connecting fitting 6 at its tip and is fixed to the winding barrel 31 at its end.

As shown in FIG. 2(A), the cleaning nozzle 5 uses, for example, a rear water discharge type in which the cleaning water is discharged obliquely toward the cleaning hose 2 side from a plurality of discharge holes 51. Not only tap water but also a desired cleaning agent can be mixed in the cleaning water. The cleaning nozzle 5 has, for example, an annular hook 52 fixed to the tip thereof.

As shown in FIG. 2B, the connecting fitting 6 is, for example, a so-called carabiner for connecting, and the tip of the wire 4 is wound around the small diameter portion 61 via the fitting 41. The gate 62 of the connecting fitting 6 is rotatable with the small diameter portion 61 side as a fulcrum and the large diameter portion 63 side facing inward.

As shown in FIG. 2(C), the large diameter portion 63 side of the gate 62 of the connecting fitting 6 is rotated inwardly, the hook 52 of the cleaning nozzle 5 is inserted into the connecting fitting 6, and the hook 52 has a large diameter. After the portion 63 is penetrated, the gate 62 is returned to the original position, so that the connecting fitting 6 and the cleaning nozzle 5 can be detachably connected.

As shown in FIG. 1, the vertical drain pipe 102 to be cleaned in the multi-layer building 100 vertically penetrates from the uppermost floor to the lowermost floor of the multi-layer building 100, and the lateral conduit 110 of each floor is The upper end is connected to the roof 101 and the lower end is connected to the second end 1032 of the horizontal drain pipe 103 in the ground. The first end 1031 of the lateral drainage pipe 103 is connected to the sewer chamber 104. Drainage on each floor of the multi-storey building 100 flows from the conduit 110, through the vertical drain pipe 102 and the horizontal drain pipe 103, to the sewer system from the hall 104.

When cleaning the vertical drain pipe 102 of the multi-story building 100, the high-pressure washing vehicle 1 is stopped near the meeting place 104 of the horizontal drain pipe 103 of the multi-story building 100. The cleaning hose 2 is guided from the meeting place 104 into the vertical drain pipe 102 via the inside of the horizontal drain pipe 103. When the motor 32 of the winch 3 is driven and the wire 4 is wound while the connecting fitting 6 is connected to the cleaning nozzle 5, the cleaning nozzle 5 that discharges the cleaning water supplied from the high-pressure pump 11 to the cleaning hose 2, The inside of the vertical drain pipe 102 rises together with the connecting fitting 6. The dirt attached to the inner wall of the vertical drain pipe 102 is scraped off by the cleaning water discharged from the cleaning nozzle 5, and the inside of the vertical drain pipe 102 is cleaned. The filth that has fallen from the inner wall of the vertical drainage pipe 102 flows into the sewer through the horizontal drainage pipe 103 and the meeting place 104 together with the wash water.

In the drainage pipe cleaning method for a multilayer building according to the first embodiment of the present invention, first, in the connecting metal fitting hanging step shown in FIG. 3(A), the upper end portion of the vertical drainage pipe 102 is placed on the roof of the multilayered building 100.

Pend to the matching bottom edge.

Next, in the nozzle feeding step shown in FIG. 3B, the washing nozzle 5 provided at the tip of the washing hose 2 is fed from the chamber 104 to the lower end of the vertical drain pipe 102 via the inside of the horizontal drain pipe 103. This feeding operation can be performed manually by an operator, but can also be performed by ejecting cleaning water from the rear water discharge type cleaning nozzle 5 to give the cleaning nozzle 5 a forward propulsion force.

After that, in a connecting metal fitting drawing step shown in FIG. 3C, cleaning water is discharged from the cleaning nozzle 5 and the connecting metal fitting 6 is pulled out to the hall 104 through the inside of the horizontal drain pipe 103. In the connecting metal fitting drawing step, the cleaning water discharged from the cleaning nozzle 5 still positioned at the lower end of the vertical drain pipe 102 flows through the horizontal drain pipe 103 toward the hall 104, and the connecting metal 6 is moved to the hall 104. Can be pulled out. Further, by pulling out the cleaning nozzle 5 in the state of discharging the cleaning water toward the meeting place 104, the connecting fitting 6 together with the cleaning nozzle 5 to the meeting room 104 can be constantly applied with the water discharge force of the cleaning nozzle 5 to the joining fitting 6. You can also withdraw.

As shown in FIG. 4(A) or (B), the connecting fitting 6 is provided with a float 64 or a resistor 65 to give an buoyancy to the connecting fitting 6 and to provide an area for receiving the flowing force or the discharging force of the washing water. The connecting metal fitting 6 may be increased in size so that the connecting metal fitting 6 can easily move toward the hall 104 in the horizontal drain pipe 103 during the connecting metal fitting drawing process.

The float 64 shown in FIG. 4A is made of a material such as sponge having a lower specific gravity and flexibility and hydrophobicity than the connecting fitting 6, and is formed in a mesh shape having a large surface area. In order to increase the surface area, not only the mesh shape but also the spiral shape can be used.

The resistor 65 shown in FIG. 4B is formed of a material such as a resin having a lower specific gravity and flexibility and hydrophobicity than the connecting fitting 6, so that the surface area on the wire 4 side becomes large. The float 64 and the resistor 65 may be provided at the tip of the wire 4.

The float 64 and the resistor 65 should be shaped and sized in consideration of the passability inside the vertical drainage pipe 102 in the nozzle feeding process, and will be described later by removing them from the connecting fitting 6 or the wire 4 after the connecting fitting drawing step is completed. There is no problem in cleaning the vertical drain pipe 102 in the cleaning process. Therefore, the floating tool 64 or the resistor 65 may be mounted before the connecting fitting hanging step, and the floating tool 64 or the resistor 65 may be removed between the connecting fitting drawing step and the connecting step.

After the connecting metal fitting drawing step, in the connecting step shown in FIG. 3D, the cleaning nozzle 5 and the connecting metal fitting 6 are connected in the meeting place 104, which is a position outside the first end 1031 of the lateral drainage pipe 103. .. This connecting work does not necessarily have to be performed inside the hall 104, and the washing nozzle 5 and the connecting metal fitting 6 can be pulled out to the outside of the hall 104.

In the cleaning process, the motor 32 of the winch 3 is driven to wind up the wire 4 while discharging the cleaning water from the cleaning nozzle 5 connected to the connecting fitting 6. The inside of the vertical drain pipe 102 is continuously cleaned from the lower end to the upper end by pulling up the cleaning nozzle 5 discharging the cleaning water from the lower end to the upper end in the vertical drain pipe 102.

As described above, in the drainage pipe cleaning method for a multi-layered building according to the first embodiment of the present invention, the connection metal fitting 6 hung from the upper end portion to the lower end portion of the vertical drainage pipe 102 is connected to the horizontal drainage pipe from the hall 104. The cleaning water discharged from the cleaning nozzle 5 that has been sent to the lower end portion through the inside 103 can be drawn out to the hall 104 through the inside drainage pipe 103. At this time, the single wire 4 is continuously arranged without interruption between the upper end portion and the lower end portion in the vertical drain pipe 102 which is the cleaning path, and the connecting metal fitting 6 at the tip of the wire 4 is cleaned. The nozzle 5 is connected.

Therefore, the high-pressure pump 11 and the motor 32 are driven to pull up the wire 4 while discharging the cleaning water from the cleaning nozzle, without interrupting the cleaning work due to the replacement work of the wire 4 with respect to the cleaning nozzle 5, or the like. The inside of the vertical drain pipe 102 can be continuously washed from the lower end to the upper end.

As shown in FIG. 5, the second cleaning system 20 used in the drainage pipe cleaning method for a multi-layer building according to the second embodiment of the present invention is the same as the cleaning system 10 shown in FIG. Since the other configurations are similar to those of the cleaning system 10, the same reference numerals as those in FIG. The flow rate/pressure gauge 7 measures the flow rate and pressure of the wash water supplied from the high-pressure pump 11 to the wash hose 2.

A drainage pipe cleaning method for a multi-layered building according to a second embodiment of the present invention is a state confirmation process shown in FIG. 6 in which the vertical drainage pipe 102 is connected before the connecting metal fitting hanging process shown in FIG. The camera 8 is hung down from the upper end portion to the lower end portion, and the adhered state of the filth on the inner wall of the vertical drain pipe 102 is confirmed by the monitor 81 as a state before cleaning in the vertical drain pipe 102.

Thereafter, the camera 8 is taken out from the vertical drain pipe 102, and the connecting metal fitting hanging process, the nozzle feeding process, the connecting metal drawing process and the connecting process shown in FIGS. 3A to 3D are sequentially executed to perform the cleaning process. To do. In the cleaning process, the flow rate of the cleaning water supplied from the high-pressure pump 11 to the cleaning hose 2 so that the measured value of the flow rate/pressure gauge 7 becomes a value according to the state in the vertical drain pipe 102 confirmed in the state confirmation process. In addition to adjusting the pressure and the pressure, the rotation speed of the motor 32 of the winch 3 is adjusted so that the pulling-up speed of the cleaning nozzle 5 becomes a value according to the state in the vertical drainage pipe 102 confirmed in the state confirming step. These adjustments are equivalent to the 1st adjustment process of this invention.

Therefore, according to the drainage pipe cleaning method for a multilayer building according to the second embodiment of the present invention, the flow rate and pressure of the cleaning water supplied from the high-pressure pump 11 in the cleaning process and the pulling rate of the wire 4 are set before cleaning. The vertical drainage pipe 102 can be adjusted according to the state of the inside, and the inside of the vertical drainage pipe 102 can be efficiently cleaned.

In the state confirmation step, the camera 8 can be connected to the connecting fitting 6 at the tip of the wire 4 and the winch 3 can be used to hang the camera 8 from the upper end to the lower end of the vertical drain pipe 102. Further, on condition that the state in the vertical drain pipe 102 before cleaning can be confirmed, a gauge or a sensor for detecting the penetration diameter in the vertical drain pipe 102 and a recording medium may be used instead of the camera 8 and the monitor 81. it can. Furthermore, in the first adjusting step, adjustment of the lifting speed of the cleaning nozzle 5 can be omitted.

As shown in FIG. 7, a third cleaning system 30 used in the drainage pipe cleaning method for a multi-layer building according to the third embodiment of the present invention is the same as the cleaning system 10 shown in FIG. A camera 9 and a monitor 91 are added, and other configurations are similar to those of the cleaning system 10, and therefore, the same reference numerals as those in FIG. The flow rate/pressure gauge 7 measures the flow rate and pressure of the wash water supplied from the high-pressure pump 11 to the wash hose 2. The camera 9 captures an image of running water in the horizontal drain pipe 103 as a cleaning status of the vertical drain pipe 102 during the cleaning process. The monitor 91 displays the image captured by the camera 9.

In the drainage pipe cleaning method for a multi-layered building according to the third embodiment of the present invention, the camera 9 is arranged in the horizontal drainage pipe 103 during the cleaning process to detect the amount of filth mixed in the running water in the horizontal drainage pipe 103. The washing condition of the vertical drain pipe 102 during the washing process is confirmed by the monitor 91, and the washing is supplied from the high-pressure pump 11 to the washing hose 2 so that the measured value of the flow rate/pressure gauge 7 becomes a value according to the washing condition. Adjust water flow rate and pressure. Further, the rotation speed of the motor 32 of the winch 3 is adjusted so that the pulling speed of the cleaning nozzle 5 becomes a value according to the cleaning condition.

Here, the cleaning status of the vertical drainage pipe 102 during the cleaning process refers to a falling status of the filth adhered to the inner wall of the vertical drainage pipe 102. That is, in the cleaning process, the high pressure cleaning water discharged from the cleaning nozzle 5 separates and drops the filth adhering to the inner wall of the vertical drain pipe 102, and the dropped filth passes through the vertical drain pipe 102 and the horizontal drain pipe 103. And wash water from the hall 104 to the sewer.

Therefore, it is possible to confirm the cleaning status of whether or not the vertical drain pipe 102 is properly cleaned from the amount of contaminants mixed in the cleaning water flowing through the horizontal drainage pipe 103 during the cleaning process, and the amount of contaminants contained in the cleaning water is confirmed. If the amount is small, it can be determined that the flow rate and pressure of the cleaning water are insufficient, or the rising speed of the cleaning nozzle 5 is too fast. Then, if the cleaning process is continued while the amount of filth contained in the wash water is small, the filth separated from the upper inner wall of the vertical drain pipe 102 accumulates in the lower portion of the vertical drain pipe 102 to cause vertical drainage. The pipe 102 may be blocked and interfere with the cleaning process.

Therefore, in the drainage pipe cleaning method for a multi-layer building according to the third embodiment of the present invention, the amount of contaminants mixed in the cleaning water flowing through the horizontal drainage pipe 103 during the cleaning process is visually confirmed by the image displayed on the monitor 92. The flow rate and pressure of the cleaning water supplied from the high-pressure pump 11 to the cleaning hose 2 are adjusted, and the pulling speed of the cleaning nozzle 5 is adjusted. These adjustments correspond to the second adjusting step of the present invention.

Thus, according to the drainage pipe cleaning method for a multilayer building according to the third embodiment of the present invention, the flow rate and pressure of the cleaning water supplied from the high-pressure pump 11 in the cleaning process, and the pulling speed of the wire 4 can be set in the cleaning process. It can be adjusted according to the washing condition of the vertical drain pipe 102 inside, and the inside of the vertical drain pipe 102 can be smoothly and efficiently washed.

It should be noted that the camera 9 and the monitor 91 can use the camera 8 and the monitor 81 included in the second cleaning system 20 of the present invention, and in the drainage pipe cleaning method for a multilayer building according to the second embodiment of the present invention. It is also possible to carry out the second adjusting step in the cleaning step after carrying out the state confirming step and the first adjusting step. Further, in the second adjusting step, adjustment of the flow rate and pressure of the wash water can be omitted.

Further, the arrangement position of the camera 9 is not limited to the inside of the horizontal drain pipe 103, but the lower end portion of the vertical drain pipe 102 and the meeting place 104 are provided on the condition that the amount of filth mixed in the wash water can be constantly checked during the washing process. It can also be placed in. However, in order to reduce the time difference between the cleaning state and the time of performing the adjustment work in the second adjustment process, it is desirable to dispose the camera 9 at a position close to the position of the cleaning nozzle 5 in the vertical drain pipe 102, and The inside of the drain pipe 102 may be raised together with the cleaning nozzle 5. In addition, instead of the camera 9 and the monitor 91, for example, a sensor and a recording medium for measuring the amount of contaminants in the cleaning water, provided that the cleaning status of whether or not the vertical drain pipe 102 is properly cleaned can be confirmed. Can also be used.

The computer 401 stores a certain amount of data in the memory 402 and then stores the water pressure adjustment value APD, the flow rate adjustment value AFD, and the rotation speed adjustment value ADD corresponding to the image data PWD input from the camera 8 before the cleaning process in the memory 402. It is read out from the relationship stored in and is output to the high-pressure pump 11 and the motor drive unit 33. Further, the water pressure adjustment value APD, the flow rate adjustment value AFD, and the rotation speed adjustment value ADD corresponding to the image data PWD input from the camera 9 during the washing process are read from the relationship stored in the memory 402, and the high pressure pump 11 and the motor are read. Output to the drive unit 33.

The computer 401 updates the relationship stored in the memory 402 when the water pressure adjustment value MPD, the flow rate adjustment value MFD, and the rotation speed adjustment value MDD that are changed by the manual operation are input during the cleaning process. As a result, the computer 401 learns an appropriate value of the flow rate and pressure of washing water and the appropriate value of the raising speed of the washing nozzle according to the state inside the vertical drain pipe 102 before the washing step and the washing state during the washing step.

Therefore, according to the fourth cleaning system 40, it is possible to contribute to the automation of the drain pipe cleaning work of the multi-layer building. In the fourth cleaning system 40, the computer 401 stores at least the relationship between the image data PWD and each of the water pressure adjustment value MPD and the flow rate adjustment value MFD and the relationship between the image data DWD and the rotation speed adjustment value ADD in the memory 402. Anything that can be stored will do.
