Description

[Technical Field]

[0001] The present invention relates to an asbestos removal method and an asbestos removal facility. [Background technology]

[0002] Measures to prevent asbestos exposure for workers involved in the demolition of existing buildings containing asbestos and measures to prevent asbestos from scattering and leaking into the general environment are considered to be extremely important issues (Non-Patent Document 1). [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] "Comprehensive Manual for Preventing Asbestos Exposure and Asbestos Dispersion / Leakage During the Demolition of Buildings, etc." Chemical Substances Control Division, Occupational Safety and Health Department, Labor Standards Bureau, Ministry of Health, Labor and Welfare, and Air Environment Division, Water and Air Environment Bureau, Ministry of the Environment, March 2021 Summary of the Invention [Problem to be solved by the invention]

[0004] Non-Patent Document 1 describes points to keep in mind when transporting waste containing asbestos. Specifically, the waste containing asbestos is packed into a dedicated waste bag, which is then placed into another dedicated waste bag, and the double-packed waste is then collected by workers in a storage area. Since the work of transporting the dedicated waste bags filled with waste is basically carried out by workers by hand, the weight of the dedicated waste bags is limited to a weight that the workers can carry when filled with waste. If the weight of the dedicated waste bags is limited in this way, the number of dedicated waste bags will increase, which will result in reduced transportation and storage efficiency and may reduce the work efficiency of the overall removal work.

[0005] The present invention aims to improve the work efficiency of asbestos removal work. [Means for solving the problem]

[0006] The present invention is an asbestos removal method for transporting asbestos from an asbestos removal work area to an external area using a cart on which a container bag made of a flexible material is placed and a double packaging bag is placed inside the container bag, and includes: a first cleaning process for roughly removing dust adhering to the cart and the double packaging bag within the asbestos removal work area; a second cleaning process for wiping or suctioning off dust adhering to the cart and the double packaging bag within a cart cleaning area connected to the asbestos removal work area; a first sealing process for sealing the inner bag of the double packaging bag placed on the cart within a first sealing area connected to the cart cleaning area; a second sealing process for sealing the outer bag of the double packaging bag placed on the cart within a second sealing area connected to the first sealing area; and a third sealing process for sealing the container bag placed on the cart within a third sealing area connected to the second sealing area and connected to the external area.

[0007] The present invention also provides an asbestos removal facility that is installed to transport asbestos from an asbestos removal work area to an external area via a cart on which a container bag made of a flexible material is placed and a double packaging bag is placed inside the container bag, and that includes: a cart cleaning area that is connected to the asbestos removal work area, where a first cleaning process is performed to roughly remove dust adhering to the cart and the double packaging bag, and where a second cleaning process is performed to remove dust adhering to the cart and the double packaging bag by wiping or suction; a first sealing area that is connected to the cart cleaning area, and where a first sealing process is performed to seal the inner bag of the double packaging bag placed on the cart; a second sealing area that is connected to the first sealing area, and where a second sealing process is performed to seal the outer bag of the double packaging bag placed on the cart; and a third sealing area that is connected to the second sealing area and the external area, and where a third sealing process is performed to seal the container bag placed on the cart. [Effects of the Invention]

[0008] According to the present invention, the work efficiency of asbestos removal work can be improved. [Brief explanation of the drawings]

[0009] [Figure 1] 1 is a plan view showing an area configuration of an asbestos removal facility according to an embodiment of the present invention. [Figure 2] 1 is a diagram for explaining an asbestos removal method according to an embodiment of the present invention. [Figure 3] 1 is a cross-sectional view of a cart used in an asbestos removal method according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an asbestos removal method and an asbestos removal facility according to an embodiment of the present invention will be described with reference to the drawings.

[0011] First, with reference to FIG. 1, an asbestos removal facility 100 according to an embodiment of the present invention will be described.

[0012] The asbestos removal facility 100 is a facility for removing waste containing asbestos from within the building 1 to an external area 4, and is mainly composed of areas 1a and 1b partitioned within the building 1 and a first security zone 2 connected to the building 1. Figure 1 is a plan view showing a schematic diagram of the area configuration of the asbestos removal facility 100.

[0013] Specifically, as shown in Figure 1, the asbestos removal equipment 100 is an isolated space isolated from the external area 4, comprising an asbestos removal work area 1a within the building 1, a trolley cleaning area 1b within the building 1 connected to the asbestos removal work area 1a, a first sealed area 2a within the first security zone 2 connected to the trolley cleaning area 1b, a second sealed area 2b within the first security zone 2 connected to the first sealed area 2a, and a third sealed area 2c within the first security zone 2 connected to the second sealed area 2b and also connected to the external area 4.

[0014] The areas are separated by curtain-like partitions 6a to 6e that sway in response to the airflow. Each partition 6a to 6e is made of a transparent vinyl sheet material and has vertical slits to allow the transfer of dollies 10 (described below) between adjacent areas.

[0015] Here, the pressure within the asbestos removal work area 1a is normally maintained at a lower pressure than the external area 4 by a dust collection device (not shown) equipped with a HEPA filter (High Efficiency Particulate Air Filter) to prevent dust such as asbestos fibers generated during the asbestos removal work from leaking into the external area 4.

[0016] Therefore, the partitions 6a to 6e provided between the areas will sway toward the asbestos removal work area 1a due to the air flow into the asbestos removal work area 1a, which has a negative pressure compared to the external area 4.

[0017] In other words, by observing the movement of the partitions 6a to 6e, it is possible to confirm whether the pressure within the asbestos removal work area 1a is maintained at a lower pressure than the external area 4, i.e., whether the dust collection device is operating normally.

[0018] Furthermore, when work is not being carried out to transport asbestos-containing waste through the first security zone 2, it is desirable to seal the partitions 6a to 6e to prevent air from flowing into the asbestos removal work area 1a through the partitions 6a to 6e in order to reduce the operating load on the dust collection device.

[0019] For this reason, in this embodiment, the partition 6b provided at the connection between the first security zone 2 and the building 1 and the partition 6e provided at the boundary between the first security zone 2 and the external area 4 are equipped with zippers (not shown), and these partitions 6b and 6e can be sealed when waste removal work is not being carried out. Note that all of the partitions 6a to 6e may be equipped with zippers.

[0020] By using the asbestos removal equipment 100 configured in this manner, asbestos-containing waste removed within the building 1 is transported to an external area 4 in the direction of the arrow shown in Figure 1 using a cart 10 described below.

[0021] In this embodiment, a second security zone 3 used for workers to enter and exit the building 1 is provided separately from the asbestos removal facility 100 described above.

[0022] The second security zone 3 comprises an anteroom 3a connected to the asbestos removal work area 1a, a washing room 3b connected to the anteroom 3a, and a changing room 3c connected to the washing room 3b and the external area 4.

[0023] The anteroom 3a is equipped with a vacuum cleaner capable of sucking up dust such as asbestos fibers adhering to protective clothing, etc., as well as a clothes basket for storing used protective clothing, and the washing room 3b is equipped with an air shower unit capable of blowing off dust.

[0024] Similar to the first security zone 2, each room is separated by partitions 7a to 7d, and among the partitions 7a to 7d, partition 7a located at the connection between the second security zone 3 and the building 1 and partition 7d located at the boundary between the second security zone 3 and the external area 4 are equipped with zippers not shown.

[0025] In this embodiment, the route for workers to enter and exit is separate from the route for transporting waste, i.e., the route for transporting waste is an independent, dedicated route that is wider than the route for workers to enter and exit, thereby ensuring that waste containing asbestos can be transported smoothly.

[0026] Next, the work carried out in each area of ​​the above-mentioned asbestos removal equipment 100, i.e., the asbestos removal method for removing waste containing asbestos from the asbestos removal work area 1a to the external area 4, will be described with reference to Figures 2 and 3. Figure 2 is a side view that schematically shows the process of removing waste, and Figure 3 is a cross-sectional view of a cart 10 used for removing waste.

[0027] First, with reference to FIG. 3, the configuration of a cart 10 used to carry out waste containing asbestos will be described.

[0028] The trolley 10 has a storage section 13 formed by a substantially square bottom wall panel 11 (bottom wall) and four side wall panels 12 (side walls) erected on the bottom wall panel 11, and four casters 15 (wheel sections) attached to the four corners of the underside of the bottom wall panel 11.

[0029] The storage section 13 is a cubic storage space, and the container bag 20 and the double packaging bag 30 are placed in the storage section 13 in advance.

[0030] The container bag 20 is a so-called flexible container bag (flexible container bag) made of a flexible material, for example, a resin fabric such as polypropylene, and has a hanging belt that allows it to be hung by a crane, etc. The container bag 20 has a square bottom, with the bottom 20a having a substantially square shape similar to the bottom wall plate 11, and is attached to the cart 10 by fixing the open end 20b of the bottom 20a to the upper end 12a of the side wall plate 12 with tape (not shown) while the bottom 20a is in contact with the upper surface of the bottom wall plate 11.

[0031] In particular, to prevent the bottom 20a and the side 20c from being loose or overlapping, the container bag 20 is attached to the storage section 13 so that the bottom 20a is aligned with the bottom wall plate 11 and the side 20c is aligned with the side wall plate 12. This ensures that the storage section 13 has a sufficient volume for storing waste.

[0032] The double packing bag 30 is a transparent bag made of plastic such as polyethylene, and is composed of an outer bag 31 and an inner bag 32 that is housed inside the outer bag 31 and has approximately the same shape as the outer bag 31. The outer bag 31 and the inner bag 32 each have a thickness of 0.15 mm or more, and the outer bag 31 in particular is printed with a message indicating that it contains waste containing asbestos.

[0033] With the bottom 31a of the outer bag 31 in contact with the bottom 20a of the container bag 20, the open end 31b of the outer bag 31 is fixed to the outer lower end 12b of the side wall panel 12 with tape (not shown) so that no gap is formed between the side wall panel 12 and the open end 31b. In other words, the outer bag 31 is attached to the cart 10 with the side portion 31c folded back at the upper end 12a of the side wall panel 12 to cover the outer surface of the side wall panel 12. Note that the open end 31b of the outer bag 31 only needs to be fixed below the outer side of the side wall panel 12, and may also be fixed with tape to the outer peripheral surface of the bottom wall panel 11 or the underside of the bottom wall panel 11, which is located below the outer lower end 12b of the side wall panel 12, so that no gap is formed between the side wall panel 12 and the open end 31b.

[0034] With the bottom 32a of the inner bag 32 in contact with the bottom 31a of the outer bag 31, the open end 32b of the inner bag 32 is fixed to the outer lower end 12b of the side wall panel 12 with tape (not shown) so that no gap is formed between the side wall panel 12 and the open end 32b. That is, like the outer bag 31, the side portion 32c of the inner bag 32 is folded back at the upper end 12a of the side wall panel 12 and attached to the cart 10 so as to cover the outer surface of the side wall panel 12. Note that the open end 32b of the inner bag 32 only needs to be fixed below the outer side of the side wall panel 12, and may also be fixed with tape to the outer peripheral surface of the bottom wall panel 11 or the underside of the bottom wall panel 11, which is located below the outer lower end 12b of the side wall panel 12, without any gap.

[0035] In addition, in order to prevent the volume for storing waste from becoming narrower, the outer bag 31 and the inner bag 32 are attached to the storage section 13 in the same manner as the container bag 20, so that there is no looseness or overlapping at the bottoms 31a, 32a or the sides 31c, 32c.

[0036] In this way, the side wall panels 12 of the cart 10 are covered with the double packaging bag 30, so that dust such as asbestos fibers generated during the asbestos removal work is prevented from adhering to the side wall panels 12.

[0037] Next, with reference to FIG. 2, the waste removal operation performed using the cart 10 having the above configuration will be described.

[0038] The asbestos removal work area 1a is an area where work is carried out to remove asbestos and materials with asbestos attached from the building 1. The asbestos, materials, etc. removed in the asbestos removal work area 1a are sequentially packed into the inner bag 32 of the cart 10 as waste.

[0039] When the amount of waste packed in the cart 10 reaches a certain amount, the cart 10 is moved near the cart cleaning area 1b.

[0040] Then, before the cart 10 is handed over to the cart cleaning area 1b, dust adhering to the surface of the cart 10 and the surface of the inner bag 32 of the double packaging bag 30 is roughly removed in the asbestos removal work area 1a (first cleaning process).

[0041] Specifically, the dust adhering to the surface of the trolley 10 and the surface of the inner bag 32 of the double packaging bag 30 is brushed off by air blown from a blower, and an agent such as a dust dispersion inhibitor that suppresses the dispersion of dust is sprayed onto the surface of the trolley 10 and the surface of the inner bag 32 of the double packaging bag 30.

[0042] After completing work in the asbestos removal work area 1a, the cart 10 passes through the partition 6a and is handed over to the cart cleaning area 1b.

[0043] In the cart cleaning area 1b, dust adhering to the surface of the cart 10 and the surface of the inner bag 32 of the double packaging bag 30 is wiped off and removed by suction (second cleaning step).

[0044] Specifically, a vacuum cleaner capable of sucking up dust such as asbestos fibers is used to suck up dust adhering to the surface of the dolly 10 and the surface of the inner bag 32 of the double packaging bag 30, and the surface of the dolly 10 and the surface of the inner bag 32 of the double packaging bag 30 is wiped with a wet cloth or the like. In particular, in the dolly cleaning area 1b, the underside of the bottom wall panel 11 of the dolly 10 and the casters 15 are carefully wiped with water.

[0045] The time required for cleaning work in the cart cleaning area 1b is relatively longer than the time required for work performed in each subsequent process. For this reason, it is desirable to ensure that the work area of ​​the cart cleaning area 1b is large enough to allow cleaning of multiple carts 10 at the same time.

[0046] After completing work in the cart cleaning area 1b, the cart 10 passes through the partition 6b and is handed over to the first sealing area 2a.

[0047] In the first sealing area 2a, after it is confirmed that there are no attachments on the surface of the carriage 10 and the surface of the inner bag 32 of the double packaging bag 30, the inner bag 32 of the double packaging bag 30 is sealed (first sealing step).

[0048] Specifically, the worker visually checks for the presence or absence of adhesions on the surface of the cart 10, particularly the underside of the bottom wall panel 11 and the casters 15, and also checks for the presence or absence of adhesions on the surface of the inner bag 32 that covers the outer surfaces of the side wall panels 12 of the cart 10. Once it is confirmed that there is no adhesion, the open end 32b of the inner bag 32 that is fixed to the outer lower end 12b of the side wall panel 12 is removed, and the open end 32b of the inner bag 32 is sealed. Note that sealing the open end 32b of the inner bag 32 means sealing the open end 32b so that air cannot enter or exit the interior of the inner bag 32.

[0049] On the other hand, if any adhesions are found, the work of wiping each part with water is carried out again in the same manner as in the second cleaning step described above. Note that each part may be wiped with water again before checking for the presence or absence of adhesions. Furthermore, the presence or absence of adhesions may be detected by image processing of images captured by a camera (not shown).

[0050] After completing the work in the first sealing area 2a, the cart 10 passes through the partition 6c and is handed over to the second sealing area 2b.

[0051] In the second sealing area 2b, the open end 31b of the outer bag 31 fixed to the outer lower end 12b of the side wall plate 12 is removed, and the open end 31b of the outer bag 31 is sealed (second sealing step). Note that sealing the open end 31b of the outer bag 31 means sealing the open end 31b so that air cannot enter or exit the inside of the outer bag 31.

[0052] In addition, an adhesive sheet 8 is laid on the floor of the second sealing area 2b, and by moving the cart 10 retracted from the first sealing area 2a on the adhesive sheet 8, any deposits adhering to the casters 15 within the first sealing area 2a are removed.

[0053] Furthermore, since the work carried out in the second sealing area 2b is carried out after the inner bag 32 of the double packaging bag 30 has been sealed and dust such as asbestos fibers adhering to the cart 10 has been sucked up or wiped away and reliably removed, it is possible to carry out the work using simpler protective clothing than that worn when working in the first sealing area 2a.

[0054] After completing the work in the second sealing area 2b, the cart 10 passes through the partition 6d and is handed over to the third sealing area 2c.

[0055] In the third sealing area 2c, the open end 20b of the container bag 20 fixed to the upper end 12a of the side wall plate 12 is removed, and the open end 20b of the container bag 20 is sealed (third sealing step). Note that sealing the open end 20b of the container bag 20 means narrowing the open end 20b as much as possible so as to reduce exposure of the outer bag 31 to the outside, and does not mean airtight sealing as in the sealing of the outer bag 31 and the inner bag 32 described above.

[0056] In this way, the double packing bag 30 is sealed and the container bag 20 containing the double packing bag 30 is also sealed, so that the cart 10 carrying the container bag 20 becomes capable of being moved outside the first security zone 2, which is an isolated space.

[0057] Therefore, the cart 10 that has completed work in the third sealing area 2c passes through the partition 6e and is handed over to a worker waiting in the external area 4.

[0058] After a worker in the external area 4 finally confirms that there is no dust or the like attached to the trolley 10, the trolley 10 is moved to a storage location (not shown) provided in the external area 4, and the container bag 20 is removed from the trolley 10 by a crane or the like and temporarily stored in the storage location.

[0059] The outer shape of the container bags 20 filled with waste inside the storage section 13 is the same as the shape of the storage section 13 of the cart 10, i.e., a shape close to a cube. By making the outer shapes of the container bags 20 uniform in this way, it becomes possible to store the container bags 20 in a regular, orderly arrangement in a storage location provided in the external area 4, compared to when the outer shapes of the container bags 20 are irregular.

[0060] After going through each of the above steps, the asbestos-containing waste is transported from the asbestos removal work area 1a to the external area 4.

[0061] Between the above-mentioned processes, only the carts 10 are handed over through the partitions 6a to 6e, and workers do not move between areas. In other words, since workers stay in the same area, there is no need to remove dust and the like that has adhered to the workers' protective clothing when moving to the next work process.

[0062] According to the above embodiment, the following effects are achieved.

[0063] According to the above asbestos removal method and asbestos removal equipment 100, while the cart 10 equipped with the container bag 20 and double packing bag 30 is moved from the asbestos removal work area 1a to the external area 4, dust adhering to the surface of the cart 10 is removed, and the container bag 20 and double packing bag 30 are sealed sequentially, so that the waste containing asbestos is transported from the asbestos removal work area 1a to the external area 4 via the cart 10.

[0064] By transporting waste containing asbestos using the cart 10 in this way, workers do not need to carry double packing bags 30, etc., which reduces the workload of workers and makes it possible to increase the weight of asbestos, etc. packed into the double packing bags 30.

[0065] In addition, by transporting waste containing asbestos via the trolley 10, the external shape of the container bag 20 and double-packing bag 30 filled with asbestos, etc. can be made to be similar to the shape of the storage section 13 of the trolley 10.

[0066] Therefore, the storage efficiency of the container bags 20 and double packing bags 30 filled with waste containing asbestos is improved, and as a result, the work efficiency of the asbestos removal work can be improved.

[0067] Furthermore, according to the asbestos removal method and asbestos removal equipment 100, workers do not move between areas, and only the carts 10 filled with waste containing asbestos are handed over between areas.

[0068] Therefore, when transporting asbestos and other materials from the asbestos removal work area 1a to the external area 4, only the cart 10 needs to be cleaned, and there is no need to clean the workers' protective clothing, etc., thereby improving the work efficiency of the asbestos removal work.

[0069] The following modified examples are also within the scope of the present invention, and it is possible to combine the configuration shown in the modified example with the configuration described in the above embodiment, or to combine the configurations described in the different modified examples below.

[0070] In the above embodiment, the cart cleaning area 1b is provided inside the building 1. Alternatively, the cart cleaning area 1b may be provided inside the first security zone 2 together with the first sealed area 2a and the like.

[0071] In the above embodiment, the security zone is divided into a first security zone 2 exclusively for waste removal and a second security zone 3 exclusively for worker entry and exit. Alternatively, the security zone may be composed of a single security zone.

[0072] Furthermore, in the above embodiment, the adhesive sheet 8 is provided only on the floor surface of the second sealed area 2b. The adhesive sheet 8 may also be provided in areas other than the second sealed area 2b. However, since the adhesive sheet 8 is not very effective when provided in an area where the casters 15 are wiped with water, from the viewpoint of reliably preventing the adhesion of dust and the like to the casters 15, it is more effective to provide the adhesive sheet 8 in an area where work is performed after the casters 15 have been wiped with water and it has been confirmed that there is no adhesion to the casters 15.

[0073] In the above embodiment, the storage section 13 of the cart 10 is formed by the substantially square bottom wall plate 11 and four side wall plates 12, and the shape of the storage space is cubic. Alternatively, the storage section 13 of the cart 10 may be formed by a disk-shaped bottom wall plate and cylindrical side wall plates, and the shape of the storage space may be cylindrical. In this case, the container bag 20 used is of a round-bottom type, in which the shape of the bottom 20a is circular, just like the bottom wall plates.

[0074] Although the embodiments of the present invention have been described above, the above embodiments merely illustrate some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above embodiments.
