  By the way, as a technique to divide the inside of an existing reinforced concrete civil engineering water tank or steel plate water tank, there are the following. (1) First, drain water, treated water, sludge, etc. from the water tank is once drained, and then the partition walls are constructed with concrete civil engineering walls after cleaning. (2) First, a dimensional investigation in the water tank is performed, and a partition made of steel plate or the like is manufactured based on the dimensions. Then, drain water, treated water, sludge and the like in the water tank are removed, and a partition wall is installed in the tank after cleaning. Caulking is applied to the gap between the partition wall and the existing water tank, and the space between the tanks is sealed.

  However, in any of the above conventional methods, it is necessary to drain the water in the water tank before construction, clean the inside of the tank, investigate the tank dimensions, and cure after the construction, and each process takes a period of 1 day to 1 week. Necessary. Moreover, in the case of a biological treatment tank such as an aeration tank that performs treatment using microorganisms, an acclimatization period is further required after the operation is resumed. In the case of an aeration tank, in order to reuse activated sludge, it is necessary to temporarily store the activated sludge in a temporary aeration facility such as a large temporary tank and temporarily aerate it.

  Furthermore, industrial waste costs are incurred when wastewater, sludge, and the like are once disposed of as industrial waste. Furthermore, in the case of wastewater treatment equipment installed in factories or the like, if the wastewater treatment equipment is stopped, the relevant production line is affected during that period. In many factories, a single wastewater treatment facility collectively processes wastewater discharged from a plurality of production lines, which affects the entire factory. For this reason, in the case of large-scale refurbishment such as dividing the tank of wastewater treatment equipment, another land is often prepared and wastewater treatment equipment of the same scale is installed.

  Moreover, it may be desirable that the gap between the existing wall of the water tank and the newly installed partition wall be as small as possible, and it is required that a sealed structure be easily formed.

  The present invention has been made in view of such circumstances, and the water tank can be divided by the wall body without discharging the stored liquid from the water tank, and the end of the wall body and the water tank It is an object of the present invention to provide a water tank dividing method, a water tank, and a wall body that can easily reduce a gap between an inner wall surface or a bottom surface.

  According to this invention, the wall body is installed in the water tank, and the end of the wall body is disposed along the inner wall surface and the bottom surface of the water tank. A water tank is divided | segmented by reducing the clearance gap between at least any one between an edge part and a bottom face. At this time, the hollow member is installed along at least one of the end portion of the wall body and the inner wall surface and between the end portion of the wall body and the bottom surface, and the hollow member is filled with fluid. Since the hollow member has stretchability, the hollow member is stretched by being filled with a fluid, and the gap is reliably reduced. Moreover, the water tank in which the liquid is stored can be easily divided without discharging the liquid from the water tank.

  In the above invention, the first step is a fifth step of inserting the wall body in which the distance between the both side ends of the wall body is shorter than the distance between the two inner wall surfaces into the water tank, and the wall body is extended, You may have a 6th step which installs the both ends of a wall body along an inner wall surface.

  According to the present invention, when the wall body is inserted into the water tank, the distance between the both side ends of the wall body is shorter than the distance between the two inner wall surfaces. Further, by extending the wall body, both side ends of the wall body can be quickly installed along the inner wall surface.

  In the above invention, a seventh step of separating the liquid containing two or more substances stored in the water tank into at least one substance and another substance across the wall may be further provided.

  According to the present invention, a water tank in which a liquid containing two or more substances is stored can be easily divided without discharging the liquid from the water tank, and at least one substance is contained in one section across the wall.

Embodiments according to the present invention will be described below with reference to the drawings.
A water tank dividing method according to an embodiment of the present invention is a method of dividing a processing tank 1 in operation in, for example, a wastewater treatment facility without draining water, and an end of a partition wall 3 that divides the processing tank 1 And the gap between the inner wall surface or the bottom surface of the treatment tank 1 can be easily reduced.

  The processing tank 1 is a reinforced concrete civil engineering water tank, a steel plate water tank, or a synthetic resin water tank. The wall body that divides the treatment tank 1 includes a partition wall 3, a frame member 6, a guide member 7, and the like (note that the frame member 6 and the guide member 7 before the partition wall 3 is inserted into the treatment tank 1 when the water tank is divided). May also be called a wall). The partition wall 3 that divides the processing tank 1 is made of, for example, steel or synthetic resin, and is supported by an existing inner wall surface of the processing tank 1 through a guide member 7 and a frame member 6 as shown in FIG. The

  With reference to FIG.3 and FIG.16, the junction part of the existing inner wall face and the partition 3 of the processing tank 1 which concerns on this embodiment is demonstrated. In addition, below, although the case where the inner wall surface of the processing tank 1 is processed is demonstrated, you may process similarly about the existing bottom face of the processing tank 1, and the junction part of the partition 3. FIG.

  At the joint portion, the guide member 7 is installed so as to contact the inner wall surface of the processing tank 1. The guide member 7 is, for example, a C-shaped steel having a U-shaped cross section, and is arranged upward from the bottom surface of the processing tank 1 as shown in FIG.

  As shown in FIG. 3, a steel pipe pile joint waterproof bag 9 is arranged inside the guide member 7. The steel pipe pile joint water-stop bag 9 is a hollow member having extensibility such as cloth, synthetic resin, or synthetic rubber. Like the guide member 7, the steel pipe pile joint water-stop bag 9 extends upward from the bottom surface of the treatment tank 1 along the inner wall surface. It is arranged toward. As shown in FIGS. 3 and 16, the steel pipe pile joint waterproof bag 9 is filled with underwater mortar 10. The upper end of the steel pipe pile joint water-stop bag 9 is opened before the injection of the underwater mortar 10 and is closed after the injection. The bottom side of the steel pipe pile joint water-stop bag 9 is closed so that the injected underwater mortar 10 does not leak. In the case where the bottom joint portion is treated with the steel pipe pile joint water-stop bag 9 and the underwater mortar 10, the steel pipe pile joint water-stop bag 9 is communicated with the one that treats the joint portion of the inner wall surface.

  As shown in FIG. 3, the underwater mortar 10 is injected into the steel pipe pile joint water-stop bag 9 by a hose 11. The tip of the hose 11 is installed near the bottom surface in the steel pipe pile joint water-stopping bag 9 before the underwater mortar 10 is injected, and the tip is pulled upward as the underwater mortar 10 is injected. By injecting the underwater mortar 10, the steel pipe pile joint water-stopping bag 9 is filled with the underwater mortar 10. And since the steel pipe pile joint waterproofing bag 9 has a stretching property, as shown in FIG. 16, the underwater mortar 10 is filled until the steel pipe pile joint waterproofing bag 9 contacts the inner surface of the guide member 7.

  Moreover, since the steel pipe pile joint water-stop bag 9 has extensibility and the underwater mortar 10 has fluidity, the underwater mortar 10 has a damaged portion 14 on the inner wall surface of the treatment tank 1 as shown in FIG. Filled to fill. When the steel pipe pile joint water-stopping bag 9 is disposed inside the guide member 7, an adhesive layer is provided on the surface of the steel pipe pile joint water-stopping bag 9 with double-sided tape or the like, The contact property with the inner surface of the guide member 7 may be enhanced. The underwater mortar 10 is an example of a fluid, and the fluid of the present invention is not limited to the underwater mortar 10 and may be air, for example.

  As shown in FIG. 3, the guide member 7 is supported and fixed by fixing members 8 at both ends. The fixing member 8 is, for example, an angle steel with an L-shaped cross section. The inner wall surface of the processing tank 1 and the fixing member 8, and the fixing member 8 and the guide member 7 are joined by, for example, bolt coupling.

  A frame member 6 is installed on the inner surface of the treatment tank 1 in the guide member 7. The frame member 6 is, for example, angle steel having an L-shaped cross section. A partition wall 3 is further installed on the frame member 6. The guide member 7 and the frame member 6, and the frame member 6 and the partition wall 3 are joined by, for example, bolt coupling. With the above configuration, the gap between the existing inner wall surface of the processing tank 1 and the newly installed partition wall 3 is closed so as to reduce the gap. In addition, the gap can be reduced by the steel pipe pile joint water-stopping bag 9 and the underwater mortar 10 even in a portion where the liquid level in the processing tank 1 rises and falls and is severely damaged.

  As mentioned above, although the method of joining the inner wall surface of the processing tank 1 and the partition 3 using the steel pipe pile joint water stop bag 9 and the underwater mortar 10 was demonstrated, both are the structures as shown in FIG.4 and FIG.5. It may be joined.

  First, as shown in FIGS. 4 and 5, the inner wall surface of the treatment tank 1 is finished so as to flatten the surface with underwater putty, underwater mortar, clay cement or the like so as to block the damaged portion 14. Then, the frame member 6 having an L-shaped cross section or the frame member 12 having an I-shaped cross section is installed on the surface of the inner wall surface or the repaired portion of the damaged portion.

  And the inner wall face of the processing tank 1 and the frame members 6 and 12 are joined by, for example, bolt coupling. Further, as shown in FIGS. 4 and 5, the inner wall surface and the frame members 6, 12 are provided with an underwater putty 13 along the length direction of the frame members 6, 12, and between the frame member 6 and the frame member 12. Are welded along the length direction of the frame members 6, 12. As a result, the gap between the existing inner wall surface of the processing tank 1 and the newly installed partition wall 3 is closed so as to reduce the gap.

  Next, the water tank dividing method according to the present embodiment will be described with reference to the flowchart of FIG.

  First, a preliminary survey is performed in advance of the main construction (step S1). The preliminary survey work is performed in a state where the treatment tank 1 is filled with treated water or the like. For example, the pre-investigation work investigates the damage state of the inner wall surface of the treatment tank 1 and the adhesion state of impurities by using a level and a stick measure from the surface of the water or by diving a diver in the water. Moreover, the shape by the exact dimension of the inner wall face and bottom face of the processing tank 1, an inclination, etc. is also measured.

  Then, based on the measured dimensions and shape of the inner wall surface and the bottom surface of the treatment tank 1, the partition wall 3 is manufactured at an onshore factory or the like (step S2). The partition wall 3 is manufactured together with a surface member such as a frame member 6, a steel plate installed on the frame member 6, or a screen that allows only treated water to pass without passing through a carrier.

  Moreover, in the inside of the processing tank 1, a surface treatment process is implemented in the state with which the process water etc. were satisfy | filled (step S3). In the surface treatment work, the inner wall surface is repaired in a state where treated water or the like is filled. For example, in a concave portion that is cut away from the original inner wall surface, the surface is repaired to be flat with underwater putty, clay cement, underwater mortar, or the like. By repairing with a water-resistant material, the construction period can be shortened. Further, in the portion where impurities are attached to the inner wall surface, the convex portion is scraped off using a keren rod or the like. Furthermore, when there is a deposit on the bottom surface of the treatment tank 1, the deposit is excluded to a place other than the portion where the partition wall 3 is installed.

  When the surface treatment work is completed, the installation position of the partition wall 3 is determined in a state where the treatment water 1 is filled in the treatment tank 1 (step S4). For example, an angle member (not shown) is fixed to the inner wall surface and the bottom surface with an anchor or the like in consideration of the installation position of the partition wall 3.

  On the land, on the other hand, because the partition wall 3 is installed, a framework (such as the frame member 6) of the partition wall 3 manufactured in a factory or the like is assembled (step S5). At this time of assembly, the guide member 7 shown in FIGS. 3 and 16 may also be attached to the frame member 6 on the partition wall 3. Moreover, the setup for injection | pouring of the underwater mortar 10 is performed (step S6). That is, the steel pipe pile joint waterproof bag 9 is disposed along the inside of the guide member 7. Moreover, the hose 11 is installed in the steel pipe pile joint water-stop bag 9.

  Then, the skeleton of the partition wall 3 is suspended by a crane truck or the like and installed inside the treatment tank 1 filled with treated water (step S7). At this time, the frame member 6 and the guide member 7 are fixed to the angle member previously installed in step S4. Further, the frame member 6 and the guide member 7 are fixed to the inner wall surface and the bottom surface by anchors or the like. Then, the surface member made from a steel plate for a partition is attached to the frame member 6 (step S8).

  Next, underwater mortar 10 is injected into the inside of steel pipe pile joint water-stopping bag 9 arranged along the inside of guide member 7 in the state where processing water etc. were filled in processing tank 1 (Step S9). . When the underwater mortar 10 is injected to the upper end of the steel pipe pile joint water-stopping bag 9 and it is determined that the steel pipe pile joint water-stopping bag 9 is in contact with the inner surface of the guide member 7, the injection of the underwater mortar 10 is completed. Then, the passage of water or particles is blocked by applying underwater putty or the like for the gap portion between the bottom surface of the processing tank 1 and the frame member 6 (step S10).

  Next, with reference to FIGS. 7 to 14, the process from the suspending process of the skeleton of the partition wall 3 to the installation process of the partition wall 3 inside the processing tank 1 will be described. In FIG. 8, FIG. 10, FIG. 12 and FIG. 14, the treatment water filled in the treatment tank 1 is omitted, but the treatment water and the like are filled in the treatment tank 1 in the following steps. It is done in the state.

  In the example shown in FIGS. 7 to 14, the frame member 6 includes a first frame member 15, a second frame member 16, and a third frame member 17. The 1st frame member 15, the 2nd frame member 16, and the 3rd frame member 17 are examples of a division | segmentation frame member, are divided | segmented in the insertion direction to the processing tank 1, and are mutually movable.

  First, as shown in FIGS. 7 and 8, the first frame member 15, the second frame member 16, and the third frame member 17 are arranged along the suspension member 18. FIG. 7 is a top view of FIG. The first frame member 15 and the third frame member 17 are members disposed along the inner wall surface of the processing tank 1, and the second frame member 16 is disposed between the first frame member 15 and the third frame member 17. It is a member to be installed. At this time, although not shown in FIGS. 7 and 8, the guide member 7, the steel pipe pile joint waterproof bag 9, and the hose described above are provided at the inner wall surface side end portions of the first frame member 15 and the third frame member 17. 11 is installed.

  Then, before the processing tank 1 is inserted, the first frame member 15 and the third frame member 17 are moved to the second frame member 16 side. Thereby, the distance from the inner wall surface side end portion of the first frame member 15 to the inner wall surface side end portion of the third frame member 17 is made shorter than the distance between two opposing inner wall surfaces of the processing tank 1. As a result, the frame member 6 including the first frame member 15, the second frame member 16, and the third frame member 17 is easily installed in the processing tank 1.

  Next, as shown in FIG. 9, the first frame member 15, the second frame member 16, and the third frame member 17 and the suspension member 18 are temporarily fixed by the temporary fixing member 19. Then, as shown in FIGS. 9 and 10, the first frame member 15, the second frame member 16, and the third frame member 17 are suspended by a crane truck or the like and inserted into the processing tank 1. FIG. 9 is a view of FIG. 10 as viewed from above.

  Then, as shown in FIG.11 and FIG.12, the 1st frame member 15 and the 3rd frame member 17 are moved to the both inner wall surfaces of the processing tank 1, respectively, and the frame member 6 whole is expand | extended. FIG. 11 is a top view of FIG. The inner wall surface side end portion of the first frame member 15 and the inner wall surface side end portion of the third frame member 17 are arranged along the inner wall surface of the processing tank 1. Between the inner wall surface and the first frame member 15 or the third frame member 17, between the first frame member 15 and the second frame member 16, and between the second frame member 16 and the third frame member 17. The fixing member 20 is fixed by an anchor, a bolt, a nut or the like. At this time, the partition wall 3 can be appropriately installed in the processing tank 1 by manufacturing the frame member 6 based on the dimension measured in advance.

  And as shown in FIG.13 and FIG.14, the surface member 21 is installed in the 1st frame member 15, the 2nd frame member 16, and the 3rd frame member 17, respectively. The surface member 21 is a steel plate or a screen that allows only treated water to pass through without passing through a carrier. The gaps between the first frame member 15, the second frame member 16, and the third frame member 17 and the inner wall surface or the bottom surface are closed by the method described above. FIG. 13 is a top view of FIG.

  As mentioned above, according to this embodiment, the processing tank 1 can be divided | segmented without draining in the state with which the processing water etc. were satisfy | filled in the processing tank 1. FIG. In that case, as above-mentioned, the clearance gap between the frame member 6 and the inner wall face of the processing tank 1 can be reduced rapidly and easily by the method using the steel pipe pile joint water stop bag 9 and the underwater mortar 10. Moreover, as described with reference to FIGS. 7 to 14, the partition wall 3 is easily installed in the processing tank 1 by dividing the frame member 6 to reduce the length direction or folding the frame member 6. . As a result, since the treatment tank 1 can be divided in a short period, the stop period of the factory or the like is shortened compared to the conventional method.

  Moreover, this embodiment is applicable also to the division | segmentation of the processing tank 1 in the waste water treatment facility shown in FIG. By dividing the treatment tank 1 by the partition walls 3, it can be easily modified to a wastewater treatment facility capable of more efficient treatment as shown in FIG. 1. That is, in the example shown in FIG. 15, the raw waste water is flowed to the treatment tank 1 as an activated sludge tank, and the treated water treated in the treatment tank 1 is flowed to the sedimentation tank 2. And the treated water processed by the sedimentation tank 2 is discharged | emitted further to a back | latter stage, or sludge is returned to the processing tank 1. FIG.

  On the other hand, in the wastewater treatment facility shown in FIG. 1, the first stage of the treatment tank 1 is the carrier fluidized tank 4 and the second stage is the activated sludge tank 5 after being divided by the partition walls 3. Specifically, the carrier fluidized tank 4 is loaded with a carrier that holds microorganisms at a high concentration. In the carrier fluid tank 4 (aeration tank), the carrier is flowing, and fine sludge is generated. Then, the fine sludge generated in the carrier fluid tank 4 is flowed to the activated sludge tank 5 without the carrier. The carrier does not flow from the carrier fluid tank 4 to the activated sludge tank 5 by installing the partition wall 3, the above-described sealed structure, and the carrier overflow prevention screen.

  Thereby, the treatment tank 1 in which a liquid containing two or more substances such as drainage, treated water, and sludge is stored can be easily divided before the separation. Fine sludge and the like are stored, and fine sludge, activated sludge and the like are stored in the activated sludge tank 5.

  In the activated sludge tank 5, since fine sludge is processed, the sedimentation property of sludge is improved compared with the waste water treatment facility shown in FIG. The sludge generated in the sedimentation tank 2 is returned to the activated sludge tank 5 or discharged as excess sludge.

  In the conventional construction method, the acclimatization period is required until the activated sludge is returned to the treatment tank 1 and the performance is restored. However, in this embodiment, the period required for the division of the treatment tank 1 is a short period. Can be unnecessary or can be made shorter in comparison with the prior art. Moreover, according to this embodiment, the temporary aeration equipment which stores activated sludge is unnecessary at the time of the division | segmentation of the processing tank 1, and it can implement relatively inexpensively.
