[0011] Hereinafter, a method for restoring a building that has suffered flood damage according to this embodiment will be described with reference to the drawings.

[0012] In this embodiment, the building to be restored is not particularly limited, and may be a residence such as a detached house or an apartment building, or a commercial facility such as a store or a warehouse. In addition, the restoration is not limited to the case where the entire building is flooded and restored, but includes the restoration of a building where only a part of the building is flooded. For example, the building may be a building where the entire first floor is flooded, or a building where rooms on floors other than the first floor are flooded, and further, a building where only a part of the first floor is flooded is also the target of the restoration method of this embodiment. In addition, the construction method is not particularly limited, and the building may be a wooden building or a reinforced concrete building.

[0013] (Embodiment 1) A flowchart of the work steps in the method for restoring a building damaged by flood according to embodiment 1 is shown in Fig. 1. As shown in Fig. 1, the restoration method according to this embodiment includes a disinfection step S11, an ozone fumigation step S12, and a drying step S13.

[0014] In this embodiment, an example will be given of the case of restoring the space under the floor of a house that has been flooded, where at the start of the restoration method, the water that has entered the house has already been drained and the mud under the floor has been removed.

[0015] First, in the disinfection step S11, a disinfection work is performed to disinfect the space under the floor using a disinfectant. Here, in this embodiment, the space under the floor is the target of restoration. The space under the floor refers to the space located under the floor of a building. Taking a detached house as an example, the space under the floor means the space surrounded by the rising part of the foundation, the bottom part, the foundation, the floor boards, etc. In the disinfection step S11, at least one of the bottom surface, side surface, and top surface constituting the space under the floor is disinfected according to the degree of flooding. For example, when the floor is flooded and the water is flooded to the extent that the water touches the floor, the bottom surface, side surface, and top surface constituting the space under the floor are disinfected. On the other hand, when the floor is flooded and the water does not touch the floor, the bottom surface and side surface constituting the space under the floor are disinfected. When the degree of flooding is low, only the bottom surface may be disinfected. In addition, the disinfection work may be performed only on the necessary parts, and the bottom surface, side surface, or top surface constituting the space under the floor may be disinfected in its entirety or in part. The same applies to the work in other steps.

[0016] The disinfectant used is one capable of sterilization. The disinfectant used may be, but is not limited to, a disinfectant containing hydrogen peroxide, a surfactant, and a water-soluble solvent, or a disinfectant containing chlorine dioxide. The disinfection is performed by spraying the disinfectant into the space under the floor with a sprayer or mist spray. The disinfection may also be performed by directly wiping at least one of the bottom, side, and top surfaces that make up the space under the floor.

[0017] By carrying out the disinfection step S11 prior to the next ozone fumigation step S12, it becomes possible to more effectively remove the cause of the odor.

[0018] Next, the ozone fumigation step S12 is performed. In the ozone fumigation step, the space under the floor is fumigated with ozone gas for a predetermined time. In the ozone fumigation step S12, it is preferable to seal places where gas may leak, such as vents, so that the space under the floor can be filled with ozone gas. In addition, since rubber or electronic devices may become rotten due to ozone, if these are present in the space under the floor, it is preferable to move them, and if they cannot be moved, it is preferable to cover them with vinyl or the like.

[0019] By filling the space under the floor with ozone gas, it is possible to sterilize bacteria that exist in places where liquid cannot enter or where it is difficult to wipe directly, as well as bacteria that are floating in the space. It can also decompose substances that cause odors.

[0020] In addition, as an ozone gas generator for generating ozone gas, for example, Tiger (Kai Corporation, ozone generation capacity 12,000 mg / h, output air volume 560 m 3 / h), Panther-J (Kai Corporation, ozone generation capacity 7,500mg / h, output air volume 260m 3 / h), etc.

[0021] When ozone reacts with odorous substances, the ozone concentration in the space does not increase well, so in order to fill the space under the floor with ozone gas, a sufficiently large amount of ozone must be generated. These ozone generators generate a large amount of ozone per hour, at over 7,500 mg / h, and have an air volume of 260 m 3 / h or more, it is possible to generate a sufficient amount of ozone gas for deodorization and sterilization.

[0022] In addition, in ozone fumigation work, the space in which ozone fumigation is performed is 1m 3 The amount of ozone supplied per square meter of the space where ozone fumigation is performed is preferably 50 mg or more, and more preferably 80 mg or more. 3The amount of ozone supplied per square meter of space is preferably 1000 mg or less, more preferably 500 mg or less, and even more preferably 300 mg or less. 3 The amount of ozone supplied to a space is calculated as follows. First, the total amount of ozone generated is calculated from the operating time of the ozone gas generator during the ozone fumigation work and the amount of ozone generated per hour by the ozone gas generator used. The total amount of ozone generated is divided by the volume of the space targeted for ozone fumigation to obtain the amount of ozone supplied to a space of 1 m 3 The amount of ozone to be supplied is calculated.

[0023] Ozone fumigation may be performed multiple times. If it is performed multiple times, the total amount of ozone gas generated is calculated based on the operating time of the ozone gas generator in each ozone fumigation operation. The total amount of ozone generated in each operation is added up and divided by the volume of the space to calculate the volume of ozone gas generated in 1 m of the space. 3 Calculate the amount of ozone supplied to this space. Even if ozone fumigation work is performed multiple times, 3 The amount of ozone supplied to the target object is preferably 80 mg or more and 300 mg or less.

[0024] The number of ozone gas generators used is not limited to one, but may be two or more. The number of generators to be installed can be changed depending on the volume of the space.

[0025] As an example, if the volume of a space is 150m 3 In this case, ozone fumigation can be carried out for 45 minutes to 2 hours using two ozone gas generators, Tiger and Panther-J.

[0026] In addition, since ozone can promote the generation of OH radicals, which are more reactive than ozone, it is preferable that the humidity of the space to be fumigated is high when performing ozone fumigation. For example, it is preferable that the surface of the foundation, etc. is in a wet state. In a building that has suffered flood damage, the foundation, base, etc. may not be completely dry and may be in a wet state. In the case of ozone fumigation, the high humidity state may be utilized when the foundation, base, etc. are wet.

[0027] If the humidity is insufficient, a deodorizer may be sprayed in the space under the floor to increase the humidity. A weak alkaline agent or a weak acid agent may be used as the deodorizing aid depending on the properties of the substance causing the odor. An example of such a deodorizing aid is Deodorizing Support Team (Kai Corporation).

[0028] Furthermore, it is preferable to use an agent containing hydrogen peroxide as the deodorant, since this can further promote the generation of OH radicals and further enhance the deodorant effect.

[0029] During the ozone fumigation process, it is preferable to use a blower to circulate the air so that the ozone is sufficiently distributed throughout the space under the floor.

[0030] After the ozone fumigation work, exhaust work is performed. Specifically, after a specified time has passed, the generation of ozone from the ozone gas generator is stopped, and the remaining ozone gas, by-products, etc. are removed from the space under the floor using ventilation equipment and exhaust ducts.

[0031] As described above, the ozone fumigation step S12 includes the ozone fumigation work and the exhaust work, but is not limited to a case where one set of the ozone fumigation work and the exhaust work is performed, in other words, one each of the ozone fumigation work and the exhaust work is performed. Two or more sets of the ozone fumigation work and the exhaust work can be performed as necessary. In addition, if the space under the floor is dry after the first set of the ozone fumigation work and the exhaust work is completed, an operation to increase humidity using a deodorizing auxiliary agent or the like may be performed before the second set of the ozone fumigation work. In addition, when the ozone fumigation work and the exhaust work are performed multiple times, the time of the ozone fumigation work and / or the amount of ozone supplied to the space may be different or the same for each work. The time of the exhaust work may also be different or the same for each work.

[0032] Next, in the drying step S13, a blower (with a duct) or a circulator is used to circulate the air in the space under the floor, and the entire space under the floor is dried. In the drying step, it is preferable to use only blowing air or cold air, since drying at high temperatures may lead to the growth of mold.

[0033] According to the restoration method of this embodiment, by including an ozone fumigation process, deodorization and sterilization can be performed well. Furthermore, by carrying out a disinfection process prior to the ozone fumigation process, it is possible to reduce bacteria that cause odors, and deodorization can be performed even better. Furthermore, by carrying out a drying process, it is possible to further prevent the proliferation of bacteria. In the restoration method of this embodiment, by carrying out these processes together, it is possible to restore a building that has suffered flood damage well.

[0034] (Embodiment 2) 2 shows a flowchart of the work steps in the method for restoring a flood-damaged building according to embodiment 2. In embodiment 1, an example is given in which the water that had entered the house had already been removed, but in embodiment 2, an example is given in which water remains under the floor after flooding.

[0035] The restoration method according to this embodiment includes a drainage step S21, a cleaning step S22, a disinfection step S23, an ozone fumigation step S24, a drying step S25, and a flora formation step S26, as shown in Fig. 2. The disinfection step S23, the ozone fumigation step S24, and the drying step S25 are the same as the disinfection step S11, the ozone fumigation step S12, and the drying step S13 in the first embodiment, and therefore detailed explanations are omitted.

[0036] First, in the drainage step S21, the water remaining under the floor is drained using a drainage pump or the like. It is preferable to use a pump capable of draining water to a depth of 1 mm as the drainage pump. If the amount of water is small, a dust collector can be used instead. In addition, since the longer the water remains, the more damage it will cause to the building, it is preferable to perform the drainage step S21 as soon as possible.

[0037] Next, in the cleaning step S22, the sludge is discharged and the space under the floor is cleaned using a cleaning agent. For example, a high-pressure cleaner is used to spray the cleaning agent to clean at least one of the bottom, side, and top of the space under the floor. The target to be subjected to the cleaning step S22 can be changed depending on the degree of flooding, as in the disinfection step S11 of the first embodiment. In the cleaning step S22, the sprayed cleaning agent is collected by a vacuum and discharged from under the floor. In the cleaning step S22, a wet / dry vacuum may be used. Depending on the material to be cleaned, it is possible to determine whether to use a high-pressure cleaner or a wet / dry vacuum. For example, when cleaning a concrete surface, a high-pressure cleaner can be used, and when cleaning a space under the floor of a wooden building, a wet / dry vacuum can be used. In the cleaning step S22, the cleaning agent may be sprayed and wiped up, or the cleaning agent may be sprayed and brushed with a brushing machine or the like, and then cleaned.

[0038] The cleaning agent used in the cleaning step S22 is preferably a cleaning agent containing probiotics, which are live bacteria. In addition, the cleaning agent preferably contains 50 million or more probiotics per cc.

[0039] In this embodiment, the probiotic is Bacillus subtilis, which is a bacillus bacterium. The probiotic may contain a bacillus bacterium other than Bacillus subtilis. In this embodiment, the probiotic may be one or more species selected from the group including Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, and Bacillus amyloliquefaciens, and preferably contains five or more species. Bacillus bacteria can produce enzymes and decompose organic matter by the enzymes. Organic matter that causes odor can be removed.

[0040] An example of such a cleaning agent containing probiotics is Gran Bio Pro (Kai Corporation).

[0041] In the cleaning step S22, when a cleaning agent containing probiotics is used, corrosion and the like can be prevented compared to, for example, the use of a strong alkaline cleaning agent. Also, compared to the use of synthetic detergents, stickiness is prevented, making wiping work easier, and the substances that cause odors can be broken down, resulting in a good deodorizing effect.

[0042] In the cleaning step S22, not only is sludge discharged, but the space under the floor is also cleaned, thereby reducing substances that cause odors. Also, the cleaning step S22 is not limited to being performed once, but can be performed two or more times.

[0043] After the cleaning step S22, the disinfection step S23, the ozone fumigation step S24, and the drying step S25 are performed in this order, as in the first embodiment. Here, the disinfection step S23 may be performed immediately after the cleaning step S22, or may be performed after a certain time has elapsed. Since the probiotics contained in the cleaning agent used in the cleaning step S22 are active for a certain period of time, the cleaning step S22 and the disinfection step S23 may be performed, for example, 1 to 3 days apart. Whether or not to leave a time between the cleaning step S22 and the disinfection step S23 is determined according to the target material, the damage situation, and the like. For example, in the case of a material with an uneven surface such as exposed concrete, or in the case of a long period of immersion in water, it is preferable to perform the disinfection step S23 after the cleaning step S22 with a certain time interval.

[0044] Next, after the drying step S25, the flora formation step S26 is performed. In the flora formation step S26, a flora formation agent containing probiotics is sprayed into the space under the floor, or applied to the sides, bottom, etc. of the space under the floor. In the flora formation step S26, a space flora in which good bacteria predominates is formed, and the probiotics reduce substances that cause odors, resulting in a deodorizing effect.

[0045] As the flora-forming agent, it is preferable to use a cleaning agent containing probiotics, which are live bacteria. In addition, it is preferable that the flora-forming agent contains more than 120 million probiotics per cc. After spraying or applying the flora-forming agent, the agent is naturally dried.

[0046] In this embodiment, the probiotic is Bacillus subtilis, which is a bacillus bacterium. The probiotic may include a bacillus bacterium other than Bacillus subtilis. In this embodiment, the probiotic may be one or more selected from the group including Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, and Bacillus amyloliquefaciens. Bacillus bacteria generally have high environmental resistance and suppress the growth of various bacteria. This makes it possible to suppress the generation of odors caused by the growth of various bacteria. In addition, since Bacillus bacteria can generate enzymes and decompose organic matter using the enzymes, even if organic matter that causes odor remains after the ozone fumigation step S24, it is possible to remove them and further enhance the deodorizing effect. In addition, Bacillus bacteria penetrate into the interior from the surfaces of the sides, bottom, etc. of the space under the floor to which the flora-forming agent is applied. Since the Bacillus bacteria can survive for a certain period of time, for example, 3 days or more, the deodorizing effect can be maintained for a certain period of time after the flora-forming agent is sprayed.

[0047] An example of such a flora-forming agent containing probiotics is Granbioair (Kai Corporation).

[0048] In this embodiment, the cleaning step S22 is performed using a cleaning agent containing probiotics before the disinfection step S23, the ozone fumigation step S24, and the drying step S25, thereby further reducing odor-causing substances in addition to the effects of the first embodiment. In addition, in the flora formation step S26 following the drying step S25, the flora formation agent is sprayed or applied to make the space a state in which good bacteria predominate, and odor-causing substances can be further reduced. Therefore, in the restoration method of this embodiment, by performing these steps together, the building that has suffered flood damage can be restored even better.

[0049] (Embodiment 3) 3 shows a flowchart of the work steps in the method for restoring a flood-damaged building according to the third embodiment. In the third embodiment, as in the second embodiment, an example is taken of a case in which water remains under the floor after flooding has occurred.

[0050] As shown in FIG. 3, the restoration method according to this embodiment includes a drainage step S31, a cleaning step S32, a disinfection step S33, an ozone fumigation step S34, a drying step S35, a flora formation step S36, a mold killing step S37, and a mold prevention step S38. The drainage step S31 to the flora formation step S36 are the same as the drainage step S21 to the flora formation step S26 in the second embodiment, and therefore detailed explanations are omitted. Here, the mold killing step S37 may be performed immediately after the flora formation step S36, or may be performed after a certain time interval. Since the probiotics contained in the flora formation agent are active for a certain period of time, the flora formation step S36 and the mold killing step S37 may be performed, for example, 1 to 3 days apart. Whether or not to leave a time between the flora formation step S36 and the mold killing step S37 is determined according to the target material, the state of damage, and the like.

[0051] As in the second embodiment, the drainage step S31 to the flora formation step S36 are performed, and then the mildew-killing step S37 is performed. In the mildew-killing step S37, a mildewcide is applied to at least one of the bottom, side, and top of the space under the floor. The object to which the mildew-killing step S37 is performed can be changed depending on the degree of water infiltration, as in the disinfection step S11 in the first embodiment. In addition, the material of the object to which the mildew-killing step S37 is performed is not particularly limited, and may be wood, concrete, or the like.

[0052] In the mold-killing step S37, a mold-killing agent is applied to at least one of the bottom, side, and top surfaces of the space under the floor using a roller or a brush. After application, the mold-killing agent is allowed to dry naturally. The application and drying of the mold-killing agent can be carried out one or more times. In the mold-killing step, if mold is significantly present, physical cleaning such as brushing can also be carried out to remove the mold.

[0053] Any agent can be used as the fungicide, for example, hypochlorous acid, sodium hydroxide, agents containing a surfactant, agents containing alcohol and an antifungal component, etc. Examples of the antifungal component include triazole compounds, benzothiazole compounds, isothiazoline compounds, organic iodine compounds, quaternary ammonium salt compounds, thiophene compounds, thiocyanate compounds, nitrile compounds, pyridine compounds, guanidine compounds, imidazole compounds, and quinoline compounds.

[0054] In this embodiment, since the disinfection step S33, the flora formation step S36, etc. are provided prior to the mold-killing step S37, partial sterilization effects are already obtained in these steps, so that it is not necessary to use a mold-killing agent with a strong bactericidal action.

[0055] Following the mold killing step S37, a mold prevention step S38 is performed. In the mold prevention step S38, a mold inhibitor is applied to at least one of the bottom, side, and top of the space under the floor. The object to be subjected to the mold prevention step S38 can be changed depending on the degree of water infiltration, as in the disinfection step S11 of the first embodiment. In addition, the material of the object to be subjected to the mold prevention step S38 is not particularly limited, and may be wood, concrete, etc.

[0056] In the mold prevention step S37, a mold prevention agent for removing mold is applied to at least one of the bottom, side, and top surfaces of the space under the floor using a roller or a brush. After application, the mold prevention agent is naturally dried. The application and drying of the mold prevention agent can be performed one or more times, for example, three times. Instead of application, the mold prevention agent can also be sprayed.

[0057] As the antifungal agent, any agent containing an antifungal component can be used. Examples of the antifungal component include triazole compounds, benzothiazole compounds, isothiazoline compounds, organic iodine compounds, quaternary ammonium salt compounds, thiophene compounds, thiocyanate compounds, nitrile compounds, pyridine compounds, guanidine compounds, imidazole compounds, and quinoline compounds.

[0058] Furthermore, if the building is made of concrete, a coating agent can be used instead of the antifungal agent. By applying the coating agent to the concrete surface, the surface can be protected. Furthermore, the coating agent can penetrate into cracks, providing repair and rust prevention effects. There is no particular limitation on the coating agent, but a primer containing an epoxy resin can be used.

[0059] In this embodiment, in addition to the configuration of the second embodiment, a mold-killing step S37 and a mold-preventing step S38 are further provided, thereby providing the effect of further reducing the possibility of mold growth in the future.

[0060] (Embodiment 4) A flowchart of the work steps in the method for restoring a flood-damaged building according to the fourth embodiment is shown in Fig. 4. As in the second embodiment, the fourth embodiment takes as an example a case in which water remains under the floor after flooding has occurred. As will be described later, this embodiment is characterized by including an anti-termite step S49, and therefore the building to which this embodiment is applied is a wooden structure or a building having a portion to be restored that uses wood.

[0061] 4, the restoration method according to this embodiment includes a drainage step S41, a cleaning step S42, a disinfection step S43, an ozone fumigation step S44, a drying step S45, a flora formation step S46, a mold killing step S47, a mold prevention step S48, and an anti-termite step S49. The drainage step S41 to the flora formation step S48 are the same as the drainage step S31 to the flora formation step S38 in the third embodiment, and therefore detailed description thereof will be omitted.

[0062] In the anti-termite step S49, an anti-termite agent for preventing ants, particularly termites, is applied to the wooden parts of the foundation of the space under the floor using a roller or a brush. After application, the agent is naturally dried. As the anti-termite agent, a chemical agent containing an anti-termite component is used. The application and drying of the anti-termite agent can be performed one or more times.

[0063] Anti-termite components include, but are not limited to, neonicotinoid compounds such as imidacloprid, clothianidin, nitenpyram, acetamiprid, and thiamethoxam, pyrrole compounds such as chlorfenapyr, phenylpyrazole compounds such as pyriprole, pyrafluprole, acetoprole, and ethiprole, synthetic pyrethroid compounds such as allethrin, and boric acid.

[0064] According to the restoration method of this embodiment, by further comprising a termite prevention process, it is possible to further provide the effect of preventing future decay by ants in the wooden parts of the building.

[0065] The present disclosure is not limited to the above-mentioned embodiment, and various modifications and applications are possible. For example, in the first embodiment, the configuration in which the invaded water has already been discharged is given as an example, but if water remains, the drainage step shown in the second embodiment may be further performed. The same applies to the cleaning step, and the cleaning step shown in the second embodiment may be performed before the disinfection step in the first embodiment.

[0066] In the above-described embodiments, the case where the space under the floor is cleaned without removing the floorboards has been described as an example, but the present invention is not limited to this. In the restoration method, the flooring, the base boards, etc. may be removed to expose the space under the floor. In this case, if the floor is provided with insulation, an additional step of removing the insulation may be added.

[0067] In the above embodiment, the case where there is a space under the floor, such as in a wooden detached house, is taken as an example, but the present invention is not limited to this. For example, in a case where there is no space under the floor, such as in a store, work may be performed on the floor and walls.

[0068] In each of the above-mentioned embodiments, the case where the building is flooded below the floor level has been described as an example, but the present invention is not limited to this, and the building may be flooded above the floor level. In this case, in the disinfection step S11 in the first embodiment, depending on the level of flooding, not only the disinfection of the space below the floor level but also the space above the floor level, such as the floor, walls, and pillars, can be disinfected. The same applies to the other steps in the first embodiment. Similarly, in the other embodiments, in the case of a building flooded above the floor level, the same work as that under the floor level can be performed on the space above the floor level. In this case, the area to which the work is performed can be changed depending on the damage caused by the flooding.

[0069] In addition, depending on the level of flooding above the floor level, insulation in the walls may absorb the dirty water and cause odors. In this case, the insulation may need to be removed.

[0070] Furthermore, it is also possible to add a step of removing unnecessary items from within the building to the outside before starting the restoration method or before starting any step of the restoration method.

[0071] Furthermore, before starting the restoration method or any of the steps of the restoration method, an investigation into the type of bacteria may be carried out. By investigating the type of bacteria in advance, the amount and type of chemicals can be adjusted according to the type of bacteria in at least one of the disinfection step, the fungicide step, and the antifungal step based on the investigation results.

[0072] Although the present disclosure has been described in accordance with the embodiments, the present disclosure is not limited to these embodiments. It will be obvious to those skilled in the art that various modifications, improvements, combinations, and the like are possible.
