Description

  The present invention relates to an antifouling panel construction method, and more particularly, to an antifouling panel construction method for forming an antifouling panel by connecting a plurality of antifouling panel members to a wall surface in contact with seawater, for example.

  Marine organisms such as mussels and barnacles adhere to the wall surface of the structure in contact with seawater, but such adhesion of marine organisms may be a problem. For example, power plants use seawater as cooling water, but if marine organisms adhere to the waterway (seawater channel) for drawing in seawater, the water intake flow rate may decrease, causing normal functions of the seawater channel. Will be disturbed. Therefore, many techniques have been proposed in order to prevent marine organisms from adhering to the wall surface in contact with seawater. Among them, as a technology to prevent the attachment of marine organisms without generating harmful substances, the organic material is decomposed by generating oxygen by electrolyzing the seawater using an anode sheet attached to the wall in contact with the seawater. Therefore, the technology that prevents the attachment of marine organisms is considered promising. An example of such a technique is disclosed in Patent Document 1.

Patent Document 1 discloses a marine organism in which an anode forming plate (anode sheet) is mounted on the surface of an insulating material, and a plurality of cathode forming strips extending in the flow direction of the intake channel are mounted on the back side of the insulating material. A marine organism adhesion prevention device is disclosed in which an adhesion prevention plate is disposed on the inner wall surface of a water channel, and an anode-forming plate-like body and a cathode-forming belt-like body are electrically joined to an external DC power source. In the technique of Patent Document 1, the marine organism adhesion prevention plate is composed of a plurality of composite plates (antifouling panel members). Each of these composite plates includes a panel-like titanium plate comprising a main body part, an upper overlapping part and a lower overlapping part, an insulating material disposed on the back surface of the main body part and the lower overlapping part of the panel-like titanium plate, and a panel It consists of a long stainless steel plate arrange | positioned through the insulating material at the end of the titanium plate. The long stainless steel plate has a protruding portion protruding from the lower overlapping portion of the panel-like titanium plate, and the insulating material is an insulating resin arranged in the fixed portion and a foam arranged in the other portion. It consists of materials.
Japanese Patent No. 4256319 [A01M 29/00]

  In the technology of Patent Document 1, when constructing (constructing) a marine organism adhesion prevention plate, anchor bolts are attached to both ends of the fixed portion of the composite plate in a state where the upper and lower overlapping portions of the panel-like titanium plate are overlapped. The composite plate is fixed to the inner wall surface of the intake channel by driving in, but in actual construction, seawater may not be removed while the intake channel is in use. Construction in seawater is required, and improvement in construction speed is required. However, in the construction in seawater, it is difficult to move the composite plate smoothly to a predetermined mounting position, and it takes time and effort to construct the marine organism adhesion prevention plate.

  1 to 3, an antifouling panel construction method (hereinafter simply referred to as “construction method”) according to an embodiment of the present invention includes a plurality of antifouling panel members (hereinafter simply referred to as “panel members”). The antifouling panel 10 is formed by connecting 12 to a wall surface of a structure that contacts seawater. For example, in this embodiment, the antifouling panel 10 is used in an antifouling system 100 that prevents marine organisms such as mussels and barnacles from adhering to the wall surfaces of structures in contact with seawater.

  In the following, an example in which the antifouling system 100 is applied to a concrete box culvert type seawater channel 102 will be described prior to the description of the construction method.

  As shown in FIG. 1, in the antifouling system 100, an antifouling panel 10 is attached to each of a bottom surface, a side surface, and a top surface of a concrete box culvert type sea channel 102. Then, the anode body 14 formed on the surface of the antifouling panel 10 is connected to the positive electrode of the DC power supply device 16 installed outside to flow weak electricity, thereby electrolyzing seawater to generate oxygen. Let The generated oxygen decomposes organic matter that is a nutrient of bacteria. Therefore, the antifouling system 100 can suppress the growth of bacteria, and the formation of a slime layer due to the growth of bacteria, the accompanying adhesion of algae and marine organisms. Can be prevented.

  With reference to FIG. 4 and FIG. 5, the structure of the panel member 12 is demonstrated. As shown in FIGS. 4 and 5, the panel member 12 includes a substrate 20 and an anode element 22 attached to the substrate 20, and is connected to, for example, the pipe axis direction (flowing water direction) of the seawater channel 102 to form the antifouling panel 10. To do.

  Further, the anode elements 14 are formed by connecting the anode elements 22 so as to be energized. Basically, panel members 12 connected in a row in the tube axis direction are installed on the bottom surface, the side surface, and the top surface of the sea water channel 102. If the sea water channel 102 is large, the panel members 12 12 can also be installed in the width direction.

  In this embodiment, the length in the connecting direction of the panel member 12 is 800 mm, and the length in the width direction is 2000 mm. The size of the panel member 12 is the largest in a range that does not hinder the construction work when the seawater channel 102 is in use, that is, antifouling work in seawater is required and improvement in construction speed is required. This is what you set. That is, the length in the connecting direction is the maximum length that can be carried in from the inspection manhole (standard is 900φ). The length in the width direction is the maximum length that can be transported underwater without any trouble by the worker (diver) as a result of the workability experiment.

  The substrate 20 is formed of an insulating material, for example, a synthetic resin such as a vinyl chloride resin or a polyolefin resin. The substrate 20 includes a main body 24 formed in a rectangular flat plate shape. A first fitting portion 26 is formed on the back side of one end in the connecting direction of the main body 24. A second fitting portion 28 is formed on the surface side of the other end of the main body 24 in the connecting direction. The first fitting portion 26 and the second fitting portion 28 have a rectangular cross-sectional shape protruding from the end portion of the main body 24, and are formed over the entire length of the main body 24 in the width direction. In this embodiment, the thickness of the main body 24 is 10 mm. Moreover, the thickness of the 1st fitting part 26 and the 2nd fitting part 28 is 4.7 mm, and the protrusion length is 19.7 mm. The panel member 12 can be reduced in weight by forming the substrate 20 from a foamable synthetic resin or forming a hollow portion inside the substrate 20.

  An anode element 22 is attached to the surface side of the substrate 20 using an insulating adhesive mainly composed of an epoxy resin or the like. The anode element 22 is a sheet, a film, or a plate formed of titanium into a thin film, and has a thickness of, for example, 0.3 mm. Specifically, the anode element 22 covers the entire surface of the main body 24, and one end thereof extends to the front surface side of the first fitting portion 26, and the other end extends to the back surface side of the second fitting portion 28. As shown in FIG. That is, the anode element 22 is attached to the substrate 20 so as to not only cover the entire front surface side of the substrate 20 but also to the back surface side of the second fitting portion 28. The anode element 22 does not necessarily need to cover the entire front surface side of the first fitting portion 26 and the entire back surface side of the second fitting portion 28, and the first fitting portion 26 and the second fitting portion 28 are not covered. If the anode elements 22 are in contact with each other and can be energized when fitted, and the end edges are not exposed in the seawater, a part of the first fitting portion 26 and the second fitting portion 28 is used. It is good also as a structure covered.

  The surface of the anode element 22 is preferably covered with an electric catalyst (not shown) of a platinum group metal such as platinum. By covering the surface of the anode element 22 with an electrocatalyst, oxygen can be generated efficiently while suppressing the generation of chlorine.

  Further, the panel member 12 is provided with a plurality (two in this embodiment) of through holes 30 penetrating the first fitting portion 26 and the anode element 22 affixed thereto at a predetermined interval in the width direction. . Further, a plurality of through holes 32 penetrating the second fitting portion 28 and the anode element 22 attached thereto are provided at positions corresponding to the through holes 30. The through holes 30 and 32 are used when the panel member 12 is anchored to the wall surface of the seawater channel 102. When the panel members 12 are connected to each other, the first fitting portion 26 and the second fitting that are adjacent to each other are used. It is formed so as to communicate with each other when the mating portion 28 is fitted. The through holes 30 and 32 are also used to hook a hook 72 of a pulling wire 70 that pulls the panel member 12, which will be described in detail later. The through holes 30 and 32 may be drilled at the time of construction, and may be additionally drilled if the mounting strength is insufficient.

  When such panel members 12 are connected to each other and installed on the wall surface of the seawater channel 102, the adjacent second fitting portions 28 are overlapped on the first fitting portions 26 as shown in FIGS. Fit together. Then, an anchor bolt (fixing tool) 34 is inserted into each of the through holes 30 and 32, and the panel member 12 is anchored to the wall surface of the seawater channel 102. At this time, the anode element 22 that covers the surface of the first fitting portion 26 and the anode element 22 that covers the back surface of the second fitting portion 28 are in surface contact, and the adjacent anode elements 22 are connected to be energized. . Moreover, since the other end part of the anode element 22 is wound in the 2nd fitting part 28, and the edge of the anode element 22 is not exposed in seawater, the anode element 22 (hence, the anode body 14) is curled. Is prevented. Further, when the anchor bolt 34 is tightened, the entire end portions of the adjacent anode elements 22 are evenly pressed by the substrate 20 (the first fitting portion 26 and the second fitting portion 28) and are brought into surface contact. Therefore, the conductivity of the anode body 14 can be stably secured over a long period of time.

  2 and 3, in this antifouling system 100, rail members 36 are provided at each end (four sides) of the antifouling panel 10 configured by connecting a plurality of panel members 12.

  The rail member 36 functions as a cathode when electrolyzing seawater, and also functions as an end fixing member for preventing the antifouling panel 10 from falling off and peeling off from the wall surface of the seawater channel 102. When the panel member 12 is transported to its mounting position, it also functions as a support for sliding (moving) the panel member 12 placed on its upper side.

  Specifically, as shown in FIGS. 8 and 9, the rail member 36 includes a rail body 38 and a fixing portion 40 that are formed of a metal such as stainless steel. The rail body 38 includes a first piece 42 and a second piece 44, and the first piece 42 is formed in a long rectangular flat plate shape and extends along the end surface of the antifouling panel 10. Further, the second piece 44 is formed in a long rectangular flat plate shape projecting at a right angle from one end of the first piece 42 and extends along the surface of the antifouling panel 10. That is, the rail main body 38 has a so-called rail shape, and is formed into a L-shaped cross section by the first piece 42 and the second piece 44, and is a groove formed by the inner surface side and the wall surface of the seawater channel 102. The end of the antifouling panel 10 is fitted into the part. The length of the rail body 38 in the longitudinal direction is 2000 mm, for example, and the thickness of the first piece 42 and the second piece 44 is 3 mm, for example.

  The fixing portion 40 is formed in a rectangular plate shape that protrudes in the opposite direction to the second piece 44 from the other end of the first piece 42, and is formed at predetermined intervals with respect to the longitudinal direction of the rail body 38. A through hole 46 used for anchoring is formed in the center of the fixing portion 40.

  Further, an insulator 48 such as a rubber lining for insulating the anode body 14 and the rail body 38 is provided on the inner surface side of the rail body 38. The insulator 48 covers the entire inner surface of the rail body 38, and its end extends to the upper portion of the outer surface of the rail body 38 and is folded back to the outer surface side. As shown in FIG. 10, the surface of the insulator 48 that covers the inner surface side of the first piece 42, that is, the surface of the contact portion with the end of the antifouling panel member 10, has a semicircular cross section or the like. The formed protrusion 48a is formed. Thus, when the panel member 12 is transported to the mounting position, the frictional resistance with the panel member 12 (the lower end portion) placed on the upper side of the panel member 12 is reduced. However, the friction reducing means need not be limited to the protrusion 48a of the insulator 48. Instead of or in addition to this, the surface of the contact portion with the lower end of the panel member 12 is made of silicon or the like. A suitable lubricant may be applied.

  Further, referring back to FIGS. 8 and 9, an insulator 50 such as a rubber lining is also provided on the outer surface side of the first piece 42. The insulator 50 adjusts the surface area of the conductive portion in contact with the seawater on the outer surface of the rail body 38 so that the seawater can be electrolyzed more efficiently. Further, short circuit between the anode body 14 installed on the other wall surface of the rail body 38 and the seawater channel 102 (for example, the anode body 14 on the top surface with respect to the rail body 38 on the side surface) is prevented. The thickness of the insulators 48 and 50 is 3 mm, for example.

  In such a rail member 36, the conductive portion in contact with seawater, that is, the outer surface side of the second piece 44 of the rail body 38 and the fixing portion 40 act as a cathode. Further, the width of the groove formed by the insulator 48 attached to the inner surface of the rail body 38 and the wall surface of the seawater channel 102 is set to be slightly larger than the thickness (for example, 10.3 mm) of the panel member 12. For example, 12 mm. Moreover, the height of the groove part is 25 mm, for example. That is, the rail member 36 has a certain degree of sliding so that the panel member 12 placed on the rail member 36 can be smoothly slid within a range in which the antifouling panel 10 (panel member 12) can be prevented from falling off or peeling off. The panel member 12 is supported with a degree of freedom. In addition, the conduction | electrical_connection between adjacent rail members 36 is ensured by connecting the fixing | fixed part 46 using the flat conductor 52 formed of stainless steel etc. (refer FIG. 2).

  Further, in the antifouling system 100, a plurality of cathode panels 54 extending in the width direction are provided on the surface side of the antifouling panel 10 (see FIGS. 2 and 3). The cathode panels 54 are provided at a predetermined interval with respect to the connecting direction, for example, at a rate of about one for the five panel members 12. The cathode panel 54 is not necessarily provided, but seawater can be electrolyzed more efficiently by the cathode panel 54 acting as a cathode.

  Specifically, as shown in FIGS. 11 and 12, the cathode panel 54 includes a substrate 56, a cathode body 58, and an anode element 60. The substrate 56 is formed in a long rectangular flat plate shape using an insulating material, for example, a synthetic resin such as a vinyl chloride resin or a polyolefin resin. The length of the substrate 56 is, for example, 2000 mm, its width (length in the connecting direction) is, for example, 70 mm, and its thickness is, for example, 10 mm. A cathode body 58 is embedded in the substrate 56. The cathode body 58 is formed in a long rectangular flat plate shape from a metal such as stainless steel, and extends over the entire length of the substrate 56 in the longitudinal direction. The width of the cathode body 58 is, for example, 30 mm, and the thickness thereof is, for example, 3 mm.

  An anode element 60 similar to the panel member 12 is attached to the surface side of the substrate 56. Specifically, the anode element 60 covers the entire surface of the substrate 56, and both ends of the anode element 60 extend to the back surface side end portion of the substrate 56, that is, the substrate 56 is wound up to the back surface side end portion of the substrate 56. It is pasted.

  The cathode panel 54 is provided with a mounting hole 62 that penetrates the substrate 56, the cathode body 58, and the anode element 60 at positions corresponding to the through holes 30 and 32 of the panel member 12. The attachment hole 62 is used for attaching the cathode panel 54 to the surface side of the antifouling panel 10. In this embodiment, as shown in FIG. 13, the anchor bolt 34 for connecting the panel member 12 and fixing it to the wall surface of the seawater channel is used to attach the cathode panel 54 to the antifouling panel 10. The mounting hole 62 is enlarged in diameter above the cathode body 58 (surface side) so that insulation between the anode element 60 and the anchor bolt 34 can be secured. A core member 64 is attached to the through holes 30 and 32 of the panel member 12 in order to insulate the anode body 14 and the anchor bolt 34 from each other. The core member 64 is formed of an insulating material such as synthetic resin or rubber, and includes a cylindrical portion and a flange portion formed at the upper end thereof.

  When the cathode panel 54 is attached to the antifouling panel 10 using the anchor bolt 34, the anode element 22 of the panel member 12 and the anode element 60 of the cathode panel 54 are in surface contact with each other so as to be energized. The anode element 60 also becomes a part of the anode body 14.

  Further, a projection 66 is formed on the head of the anchor bolt 34 that fixes the cathode panel 54 so as to protrude about several cm from the surface of the cathode panel 54. The protrusion 66 is not necessarily formed, but seawater can be electrolyzed more efficiently by the portion protruding from the surface acting as a cathode.

  11 and 12, the cathode panel 54 is provided with mounting holes 68 that penetrate the substrate 56, the cathode body 58, and the anode element 60 at both ends in the longitudinal direction. The attachment hole 68 is used for attaching the cathode panel 54 to the surface side of the antifouling panel 10 and is used for conducting the rail body 38 of the rail member 36 and the cathode body 58 of the cathode panel 54. For example, a branch portion may be formed in the conductive body 52 that connects the adjacent rail members 36, and the branch portion may be connected to the cathode body 58 of the cathode panel 54 and fixed by the anchor bolt 34 (see FIG. 2). As a result, the rail main body 38 of the rail member 36 is connected to the anchor bolt 34 and the cathode body 58 (in-plane cathode member) installed in the antifouling panel region, and for the cathode for energizing the in-plane cathode members 34 and 58. It will also function as a conductor.

  A through hole is also formed in the panel member 12 at a position corresponding to the mounting hole 68 of the cathode panel 54, and the anode body 14 and the anchor bolt 34 are insulated from the through hole of the panel member 12. A core member 64 is attached. In addition, the mounting hole 68 is expanded in diameter at a portion above (the front surface side) from the cathode body 58 so that insulation between the anode element 60 and the anchor bolt 34 can be secured and the conductive body 52 can be connected. The end side is notched.

  Here, with reference to FIG.2, FIG.3, FIG.14-18, an example of the construction method which forms the antifouling panel 10 by connecting the panel member 12 and attaching to the wall surface of the seawater channel 102 is demonstrated. .

  In addition, although the case where the panel member 12 is attached to the side surface of the sea channel 102 is described here, the panel member 12 can be similarly attached to the top surface and the bottom surface of the sea channel 102. The panel member 12 may be installed in the seawater channel 102 by removing seawater from the seawater channel 102. If the seawater channel 102 is in use and cannot be removed, You may make it perform.

  First, as shown in FIG. 14, rail members 36 are linearly arranged on the lower part of the side surface of the seawater channel 102, and are sequentially attached using anchor bolts 34.

  Next, the panel member 12 is carried into the construction site (that is, around the side surface in the sea channel 102) from an inspection manhole or the like, and the panel is placed on the rail member 36 (inner surface side) attached to the side surface of the sea channel 102. The member 12 is placed and the panel member 12 is attached to the pulling wire 70. Specifically, as shown in FIG. 15, the panel member 12 is fitted and temporarily placed in a groove formed by the inner surface side of the rail member 36 and the wall surface of the seawater channel 102, and as shown in FIG. 16. The hook 72 of the pulling wire 70 is hooked in the through hole 32 of the panel member 12.

  For example, in this embodiment, the pulling wire 70 includes a main body portion 70a made of a steel wire, a stainless steel wire, or the like, and a plurality of branch portions 70b that branch from the main body portion 70a with a certain distance from each other. The pulling wire 70 extends along the rail member 36, and one end thereof is hooked on a pulley appropriately disposed in the sea channel 102 and wound around a winch (not shown). A hook 72 is provided at the tip of each branch part 70b. However, the structure of the pull wire 70 can be changed as appropriate without departing from the spirit of the present invention.

  Subsequently, as shown in FIG. 17, the panel member 12 is wound on the winch with the winch while the panel member 12 is placed on the rail member 36 (that is, supported by the rail member 36). The panel member 12 is slid (moved) along the longitudinal direction of the rail member 36 (the direction in which the rail members 36 are arranged side by side). Then, the next panel member 12 is placed on the rail member 36, and the panel member 12 is attached to the pulling wire 70. However, the panel member 12 may be mounted on the rail member 36 after being attached to the pulling wire 70. It should be noted that the hook 72 is not shown in FIG. 17 for the sake of simplicity. The same applies hereinafter.

  Then, as shown in FIG. 18, the operation of mounting the new panel member 12 on the rail member 36 in order and attaching it to the pulling wire 70 is repeated while moving the leading panel member 12 toward the attachment position.

  When the leading panel member 12 and the adjacent panel member 12 reach their respective attachment positions, the panel member 12 is removed from the pulling wire 70 and remains mounted on the rail member 36. 12 are connected (that is, the leading panel member 12 and the panel member 12 adjacent thereto) are attached to the wall surface of the seawater channel 102. That is, the adjacent second fitting portion 28 is fitted on the first fitting portion 26 so as to overlap each other, and the anchor bolt 34 is inserted into each of the through holes 30 and 32 to The panel member 12 is anchored.

  Thereafter, in the same manner, while moving the leading panel member 12 toward the predetermined attachment position, the new panel member 12 is sequentially placed on the rail member 36 and attached to the pulling wire 70, and the predetermined attachment position is set. The antifouling panel 10 is formed over the entire construction portion by repeating the work of connecting and anchoring the panel members 12 that have reached the end. At this time, the cathode panel 54 is also anchored at the same time as the panel members 12 are connected and anchored at a ratio of, for example, about five panel members 12 as described above. Note that the cathode panel 54 may be mounted on the rail member 36 and attached to the pulling wire 70 instead of the panel member 12 at a ratio of about one to the five panel members 12.

  When the antifouling panel 10 is formed over the entire construction portion in this way, the rail members 36 are attached to the upper side of the antifouling panel 10 and both ends in the connecting direction as shown in FIGS. When attaching the rail members 36 to both ends of the antifouling panel 10 in the connecting direction, the lower side of the second fitting portion 28 of the leading panel member 12 and the upper side of the first fitting portion 16 of the rearmost panel member 12 are used. A spacer 74 formed in a rectangular parallelepiped shape may be attached to the space. Further, the adjacent rail members 36 and the adjacent rail member 36 and the cathode panel 54 are connected so as to be energized using the conductive body 52 and the anchor bolt 34.

  Thereafter, the anode body 14 formed on the surface of the antifouling panel 10 is connected to the positive electrode of the DC power supply device 16 installed outside, and the rail member 36 is connected to the negative electrode of the DC power supply device 16. Then, the construction of the antifouling panel 10 on the wall surface of the sea channel 102 is finished.

  As described above, in this embodiment, the rail member 36 is mounted side by side on the wall surface of the seawater channel 102, the panel member 12 is placed on the rail member 36, and the panel member 12 is slid along the rail member 36. Therefore, the panel member 12 can be easily and accurately moved to the attachment position. Further, when the panel members 12 are connected to each other and anchored to the wall surface, this operation can be performed in a state where the panel member 12 is supported and restrained by the rail member 36. The temporary fixing to the wall surface of 12 becomes easy, and thereby the installation work of the panel member 12 becomes easy. Therefore, according to this embodiment, the antifouling panel 10 can be formed with a simpler construction.

  Furthermore, since the panel member 12 is supported by the rail member 36 and stopped, the panel members 12 can be connected to each other and attached to the wall surface to prevent the panel member 12 from being displaced. It becomes possible to connect the anode elements 22 appropriately and reliably, and as a result, it is possible to stably ensure the electrical conductivity of the anode body 14.

  Furthermore, in this embodiment, the plurality of panel members 12 are attached to the pulling wire 70, and the plurality of panel members 12 are pulled together by the pulling wire 70. It can be moved smoothly to the mounting position. Accordingly, the plurality of panel members can be smoothly moved to the respective attachment positions, so that the antifouling panel can be easily constructed and the construction speed can be improved.

  In the above-described embodiment, the rail member 36 is linearly arranged and attached to the wall surface of the seawater channel 102, and the panel member 12 is slid linearly along the rail member 36. However, the present invention is not limited to this. There is no need to be done. The rail members 36 may be arranged so that some of the rail members 36 form a predetermined angle.

  Moreover, in the above-mentioned Example, while setting the length of the connection direction of the panel member 12 to the maximum length which can be carried in from the inspection manhole, the length of the width direction is transported underwater without any trouble. Set to the maximum possible length. That is, in the above-described embodiment, the panel member 12 is formed so that the length in the vertical direction is larger than the length in the horizontal direction when the panel member 12 is upright. However, in this case, since the center of gravity becomes high when the panel member 12 is erected, the panel member 12 placed on the rail member 36 may fall down without being stably erected. .

  Therefore, as shown in FIG. 19A, the panel member 12 may be placed on the rail member 36 in a state where the panel member 12 is tilted sideways, and the center of gravity of the panel member 12 may be lowered. And after sliding the panel member 12 along the rail member 36, as shown in FIG.19 (b), you may make it raise the panel member 12 vertically and make it stand upright. In this way, the panel member 12 can be stably placed on the rail member 36, so that the possibility of the panel member 12 falling down can be avoided.

  However, if there is no difference in size between the length in the vertical direction and the length in the horizontal direction of the panel member 12, there is no need to tilt the panel member 12 sideways or to raise it vertically after moving.

  Further, for example, the length in the connecting direction of the panel member 12 is set to the maximum length that allows the operator to carry the water underwater without any trouble, and the length in the width direction of the panel member 12 can be carried from the inspection manhole. Even when the panel member 12 is formed so that the length in the vertical direction is smaller than the length in the horizontal direction when the panel member 12 is set up to the maximum length, the center of gravity is lowered when the panel member 12 is set upright. Therefore, the possibility that the panel member 12 will fall can be avoided.

  Furthermore, in the above-described embodiment, the frictional resistance between the rail member 36 and the panel member 12 is reduced by providing the protrusion 48a having a semicircular cross section at the contact portion of the insulator 48 of the rail member 36 with the panel member 12. However, the cross-sectional shape of the protrusion 48a is not particularly limited, and may be formed in a triangular shape or a rectangular shape.

  As shown in FIGS. 20 and 21, as a friction reducing means, a wheel 76 is provided at one end (for example, the lower end) in the width direction of the substrate 20 of the panel member 12 instead of the protrusion 48a of the insulator 48. It may be. The wheels 76 are rotatably supported by the axle 78 in the connecting direction of the panel member 12. For example, in the embodiment shown in FIGS. 20 and 21, the two wheels 76 have a predetermined interval in the connecting direction of the panel member 12. Spaced apart. Thus, when the panel member 12 is moved along the rail member 36, the friction between the panel member 12 and the rail member 36 is eliminated or reduced by the rotation of the wheel 76. 12 can move smoothly along the rail member 36.

  Furthermore, in the above-described embodiment, the rail member 36 is provided at each of the end portions (four sides) of the antifouling panel 10 and the cathode panels 54 are provided at predetermined intervals in the connecting direction. The rail member 36 and the cathode panel 54 may be omitted as appropriate.

  For example, when the construction length of the antifouling panel 10 is short, the rail member 36 may be provided on each of the four sides of the antifouling panel 10 without providing the cathode panel 54.

  Further, it is not always necessary to provide the rail members 36 on each of the four sides of the antifouling panel 10, and if at least the rail members 36 on the bottom surface side of the antifouling panel 10 are attached in advance to the wall surface of the seawater channel 102, As described above, the panel member 12 can be easily and accurately moved to its mounting position, and the installation work of the panel member 12 becomes easy, so that the antifouling panel 10 can be formed by simple construction. Become.

  Furthermore, in the above-described embodiment, the rail member 36 on the lower side of the antifouling panel 10 is attached to the side surface of the seawater channel 102 in a straight line, and after the panel member 12 is transported and installed, the antifouling panel 10 Although the rail member 36 is provided on each of the remaining three sides (the upper side of the antifouling panel 10 and both ends in the connecting direction), it is not necessary to be limited to this. For example, although not shown, the lower (bottom surface) rail member 36 and the upper (top surface) rail member 36 are attached to the side surface of the sea channel 102 in a straight line. The rail member 36 may be attached to both ends of the antifouling panel 10 in the connecting direction after the panel member 12 is transported and installed. In this case, since the panel member 12 can be sandwiched between the upper and lower rail members 36 when the panel member 12 is transported and installed, the panel member 12 can be stably moved to its mounting position, and the panel The installation work of the member 12 can be performed more easily. Further, when the panel member 12 is transported and attached, for example, an operator does not need to support the panel member 12 by hand. Furthermore, in this way, for example, when the antifouling panel 10 is constructed on a surface other than the side surface of the seawater channel 102 (particularly, the top surface), the panel member 12 is easily and accurately moved to its mounting position. And the installation work of the panel member 12 becomes easy.

  Furthermore, in the above-described embodiment, the panel member 12 is slid along the rail member 36 by pulling the panel member 12 with the pull wire 70. However, the present invention is not limited to this. The panel member 12 may be slid along the rail member 36 by the operator (diver) pushing it with his / her hand and carrying it underwater.

  Furthermore, in the above-described embodiment, the rail member 36 on the bottom surface side of the antifouling panel 10 is attached in advance to the wall surface of the sea channel 102, and the panel member 12 is slid along the rail member 36 to a predetermined attachment position. Although the panel member 12 is installed while being moved or placed on the rail member 36, the rail member 36 on the bottom surface side of the antifouling panel 10 is not necessarily attached to the wall surface of the seawater channel 102 in advance. There is no need.

  As an example, a construction method for forming the antifouling panel 10 without attaching the rail member 36 on the bottom side of the antifouling panel 10 to the wall surface of the seawater channel 102 in advance will be described below. In this case, the panel member 12 is installed in the seawater channel 102 in the seawater without removing the seawater from the seawater channel 102.

  Referring to FIG. 22, first, panel member 12 is carried into the construction site from an inspection manhole or the like, and panel member 12 is attached to pulling wire 70.

  Then, by winding the pulling wire 70 with a winch and pulling the panel member 12, the operation of sequentially attaching the new panel member 12 to the pulling wire 70 is repeated while moving the leading panel member 12 toward the mounting position.

  When the leading panel member 12 and the adjacent panel member 12 reach their respective attachment positions, the panel members 12 are removed from the pulling wire 70, and the panel members 12 are connected to each other on the wall surface of the sea channel 102. Install.

  Thereafter, in the same manner, while moving the leading panel member 12 toward the predetermined attachment position, the new panel member 12 is attached to the pulling wire 70 and the panel members 12 that have reached the predetermined attachment position are connected to each other. By repeating the anchoring operation, the antifouling panel 10 is formed over the entire construction portion. At this time, for example, at a ratio of about one to five panel members 12, the panel members 12 are connected and anchored, and at the same time, the cathode panel 54 is anchored.

  In this way, when the antifouling panel 10 is formed over the entire construction portion, the rail members 36 are attached to the bottom surface side, the top surface side, and both ends in the connection direction of the antifouling panel 10 as necessary.

  In the embodiment shown in FIG. 22, the panel member 12 is slid along the rail member 36 and moved to the mounting position, or the adjacent panel members 12 are connected to each other while being mounted on the rail member 36 to fix the anchor. However, since the plurality of panel members 12 are pulled together by the pulling wire 70, the plurality of panel members 12 can be smoothly moved to their respective attachment positions. Therefore, the construction of the antifouling panel can be easily performed, and the construction speed is also improved.

  Furthermore, in the above-described embodiment, the antifouling panel 10 is individually constructed on each wall surface of the sea channel 102, but it is not necessary to be limited to this.

  As an example, a panel member group 80 in which panel members 12, 82 and 84 are connected in the circumferential direction of a concrete box culvert-type sea channel 104 having a haunch is configured, and the panel member group 80 is used as a tube axis of the sea channel 102. A construction method in which the antifouling panel 10 is formed by connecting in a direction and attaching to the wall surface of the seawater channel 104 will be described below.

  First, as shown in FIGS. 23 (a) and 23 (b), the rail members 36 on the bottom surface side of the antifouling panel 10 are arranged in a straight line with respect to each of the two side surfaces of the seawater channel 104. The anchor bolts 34 are used for sequential attachment.

  Next, the panel member 12, the panel member 82 (12) for the hunch, the panel member 84 (12) for the top surface, and the connecting member 86 are carried into the construction site from the inspection manhole or the like, and FIG. And as shown in FIG.24 (b), the panel member 12 is mounted on the rail member 36 attached to each side surface of the seawater channel 102 (inner surface side), respectively. It should be noted that the panel member 82 for the haunch and the panel member 84 for the top surface are the other portions except that the length in the width direction is adapted to the haunch portion or the top surface of the sea channel 104. Since it is formed in the same manner as the panel member 12 described above, detailed description is omitted.

  Subsequently, the panel members 12 that cover the side surfaces of the seawater channel 102 are connected to each other by using the panel member 82 for the haunch, the panel member 84 for the top surface, and the connecting member 86.

  Specifically, as shown in FIG. 25, one end of a panel member 82 for a haunch in which the upper end portion of the panel member 12 covering one side surface of the sea channel 102 is set along one haunch portion of the sea channel 104. And the other end portion of the haunch panel member 82 is connected to one end portion of the top panel member 84 along the top surface of the seawater channel 104 by the connection member 86. Further, the other end portion of the panel member 84 for the top surface is connected to one end portion of the panel member 82 for the haunch along the other haunch portion of the seawater channel 104 by the connecting member 86, and the haunch. The other end of the panel member 82 is connected to the upper end of the panel member 12 that covers the other side surface of the seawater channel 102 by the connecting member 86. By doing so, a panel member group 80 that covers the two side surfaces and the top surface of the sea channel 102 is configured.

  Here, the connecting member 86 connects the panel members 12 and electrically connects the anode elements 22 of the panel members 12 (that is, enables energization). In brief, as shown in FIG. 26, the connecting member 86 includes a substrate 88 and an anode element 90, and is provided on the surface side of the adjacent panel members 12, 82, 84 across the adjacent panel members 12, 82, 84. The substrate 88 is made of an insulating material and is formed in a plate shape that is bent in accordance with an angle formed by adjacent panel members 12, 82, and 84. The anode element 90 is affixed to the substrate 88 so as to cover the entire surface of the substrate 88 and to wind both ends of the substrate 88 to the back side of the substrate 88. Further, the connecting member 86 is provided with a plurality of (two in this embodiment) through holes 92 penetrating the substrate 88 and the anode element 90 attached thereto at a predetermined interval in the width direction. However, the through hole 92 may be drilled at the time of construction, and may be additionally drilled if the mounting strength is insufficient.

When connecting panel members using such a connecting member 86, a fixing tool 94 such as a rivet or a screw is inserted into each through hole 92 of the connecting member 86, and adjacent panel members 12, 82, 84 are inserted. The connecting member 86 is pressed against each of the two . By doing so, the anode element 90 of the connecting member 86 is brought into surface contact with the anode element 22 of the panel member 12 so as to press each other, and the anode elements 22 of the adjacent panel members 12, 82, 84 are electrically connected to each other ( Connected).

  Returning to FIG. 25 (b), when the panel member group 80 covering the two side surfaces and the top surface of the seawater channel 102 is configured, both side surfaces (that is, the two panel members 12) of the panel member group 80 are connected to the pulling wire 70. Attach to. At this time, if the two pulling wires 70 are used to attach and pull the pulling wires 70 on the respective side surfaces of the panel member group 80, the panel member group 80 can be stably moved.

  Then, by pulling the pulling wire 70 with a winch and pulling the panel member group 80, the new panel member group 80 is sequentially placed on the rail member 36 while moving the leading panel member group 80 toward the mounting position. Configure and repeat the work of attaching to the puller wire 70.

  When the leading panel member group 80 and the panel member group 80 adjacent thereto reach the respective attachment positions, the panel member group 80 is detached from the pulling wire 70, and the panel member groups 80 are connected to each other to connect the seawater channel. It is attached to the wall surface of 102. Specifically, the first fitting portion 26 of each panel member 12, 82, 84 of the front panel member group 80 is connected to the second fitting portion of each panel member 12, 82, 84 of the panel member group 80 that follows. 28, and the anchor bolts 34 are inserted into the through holes 30 and 32 of the panel members 12, 82, and 84 to fix the panel member group 80 to the wall surface of the seawater channel 102.

  Thereafter, similarly, the leading panel member group 80 is moved toward a predetermined attachment position, and a new panel member group 80 is sequentially formed on the rail member 36 and attached to the pulling wire 70. By repeating the operation of connecting and anchoring the panel member groups 80 that have reached the attachment position, the antifouling panel 10 is formed over the entire construction portion. At this time, for example, the panel member groups 80 are connected and anchored at a ratio of about one to the five panel member groups 80, and at the same time, any one of the panel members 12, 82, The cathode panel 54 is anchored to 84. And if the pollution protection panel 10 is formed over the whole construction part, the rail member 36 will be attached to the both ends of the connection direction of the pollution protection panel 10 as needed.

  As described above, also in the embodiment shown in FIGS. 23 to 26, the panel member group 80 is slid along the rail member 36 and moved to a predetermined mounting position, or the panel member group 80 is placed on the rail member 36. Since the panel member group 80 which fits can be connected and an anchoring can be carried out, the antifouling panel 10 can be formed now by simple construction.

  Moreover, since the antifouling panel 10 can be constructed on the two side surfaces and the top surface of the seawater channel 102 in one operation, the construction efficiency is improved.

  In the embodiment shown in FIGS. 23 to 26, the panel member group 80 is configured by connecting the panel members 12, 82, and 84 adjacent in the width direction with the connecting member 86, but is limited to this. There is no need. Although illustration is omitted, a panel member group 80 in which the panel members 12, 82 and 84 are connected in a foldable manner via hinges is formed in advance, and the panel member group 80 is folded and carried to the construction site. Then, the panel member group 80 may be expanded and placed on the rail member 36.

  23 to 25, the antifouling panel 10 formed by connecting a plurality of panel member groups 80 to the two side surfaces and the top surface of the seawater channel 104 is constructed. The antifouling panel 10 may be applied to the bottom surface of the sea channel 104. However, since sand or the like accumulates on the bottom surface of the sea channel 104, the formation of a slime layer due to the propagation of bacteria and the accompanying adhesion of algae and marine organisms are unlikely to occur. There is no need to install the antifouling panel 10.

  Furthermore, the antifouling panel 10 may be constructed not only on the concrete box culvert type seaways 102 and 104 but on the wall surface in contact with the seawater. The antifouling panel 10 can be applied to the open channel), or the antifouling panel 10 can be applied to the bridge pier or the coastal wall.

  Furthermore, even if the wall surface in contact with seawater is a curved surface, it is possible to construct the antifouling panel 10 by forming the panel member 12 into a curved plate shape corresponding to the curvature of the wall surface.

  As an example, a construction method for forming the antifouling panel 10 on the wall surface (curved surface) of the sea channel 106 having a circular cross section will be described below.

  First, as shown in FIGS. 27 (a) and 27 (b), the anchor bolts 34 are arranged so that the rail members 36 are arranged in a straight line at positions facing each other in the vicinity of the center of the seawater channel 106 in the height direction (vertical direction). Install sequentially using

  Next, the panel member 96 (12) formed in a curved plate shape corresponding to the curvature of the wall surface of the sea channel 106 is carried into the construction site, and as shown in FIGS. 28 (a) and 28 (b) The panel member 96 is placed on the rail member 36 (inner surface side) facing each other so that the member 96 is along the upper portion (for example, the upper half) of the wall surface of the seawater channel 106. The vicinity of both ends in the bending direction is attached to the pulling wire 70. At this time, if the pulling wires 70 are attached to the respective end portions of the panel member 96 and pulled by using the two pulling wires 70, the panel member 96 can be moved stably. In addition, the panel member 96 is formed in the same manner as the panel member 12 described above except for being bent into a curved plate shape corresponding to the curvature of the wall surface of the seawater channel 106. Description is omitted.

  Then, by pulling the pulling wire 70 with a winch and pulling the panel member 96, the new panel member 96 is sequentially placed on the rail member 36 while moving the leading panel member 96 toward the mounting position. Then, the operation of attaching to the pulling wire 70 is repeated.

  When the leading panel member 96 and the panel member 96 adjacent to the leading panel member 96 reach their respective attachment positions, the panel members 96 are removed from the pulling wire 70, and the panel members 96 are connected to each other on the wall surface of the sea channel 102. Install.

Thereafter, in the same manner, while moving the leading panel member 96 toward a predetermined mounting position, new panel members 96 are sequentially placed on the rail member 36 and attached to the pulling wire 70, and the predetermined mounting is performed. The antifouling panel 10 is formed over the entire construction portion by repeating the operation of connecting and anchoring the panel members 96 that have reached the position. At this time, for example , the panel members 96 are connected and anchored at a ratio of about one to five panel members 96, and at the same time, the cathode panel is formed in a curved plate shape corresponding to the curvature of the wall surface of the seawater channel 106. 54 is also anchored. And if the antifouling panel 10 is formed over the whole construction part, the rail member 36 will be attached also to the connection direction both ends of the antifouling panel 10 as needed.

  As described above, also in the embodiment shown in FIGS. 27 and 28, the panel member 96 is slid along the rail member 36 and moved to a predetermined mounting position, or adjacent to the panel member 96 while being placed on the rail member 36. Since the panel members 96 can be connected and anchored, the antifouling panel 10 can be formed by simple construction.

  In the embodiment shown in FIGS. 27 and 28, rail members 36 are attached at opposite positions in the vicinity of the center in the height direction of the sea channel 106 to prevent the upper wall (for example, the upper half) of the sea channel 106. Although the dirty panel 10 is constructed, for example, when the antifouling panel 10 is constructed on the wall surface of the lower part (for example, the lower half) of the sea channel 106, the panel member is formed along the wall surface of the lower part of the sea channel 106. The panel member 96 may be moved to a predetermined attachment position by sliding the 96. Further, the panel member 96 can be connected and attached to the wall surface in a state where the panel member 96 is supported and restrained by the lower wall surface of the sea channel 106, so that the rail member 36 is unnecessary. is there. That is, in this case, the lower wall surface of the seawater channel 106 functions as the rail member 36.

  Further, the panel member 96 may be configured by dividing the panel member 96 at the center in the width direction (curving direction) and connecting the panel member 96 so as to be foldable via a hinge. In this case, it becomes easy to carry the panel member 96 into the construction site.

  By the way, in each of the above-described embodiments, the panel members 12 are connected to each other by fitting the end portions of the panel members 12 so as to overlap each other and anchoring them to the wall surface of the seawater channel. There is no need to be done. The panel member 12 described above is merely an example, and the shape of the panel member 12 can be changed as appropriate without departing from the scope of the present invention. Further, the rail member 36 is not limited to the panel member 12 and can be used by being attached to an end portion of a panel member (antifouling panel) having another configuration.

  Further, in each of the above-described embodiments, the second piece 44 is formed over the entire length of the first piece 42 of the rail body 38. However, the present invention is not limited to this. On the other hand, the second piece 44 may be partially formed. For example, a notch may be formed at predetermined intervals in the longitudinal direction with respect to the second piece 44. The first piece 42 is also formed with a plurality of through-holes (notches) arranged in the longitudinal direction, that is, in the form of a long plate having through-holes, so that the mounting member 10 can be reduced in weight. Also good.

  Furthermore, if the rail main body 38 of the rail member 36 has at least the first piece 42, the rail member 36 can be used as a support on which the panel member 12 is placed. That is, when the rail member 36 is not used as an end fixing member for preventing the antifouling panel 12 from dropping or peeling off, the second piece 44 may not be formed.

  Further, in each of the embodiments described above, the rail member 36 is made to function as a cathode and a cathode conductor, but the rail member 36 is not necessarily used as a cathode and a cathode conductor. When the rail member 36 is not used as a cathode conductor, the cathode body 58 may be energized by providing a cathode conductor separately. Further, the rail member 36 can be used as an anode by making the rail body 38 of the rail member 36 made of titanium or by covering the rail body 38 with a titanium sheet. When the rail member 36 is used as an anode, the insulators 48 and 50 are not necessary.

  In each of the above-described embodiments, titanium is used as the material for the anode elements 22, 60, and 90 that act as the anode, and stainless steel is used as the material for the rail body 38 and the cathode body 58 that act as the cathode. These materials may be appropriately changed as long as seawater can be electrolyzed to generate oxygen. However, it preferably has resistance to corrosion. In addition, since electricity flows also to the cathode, resistance to corrosion can be expected even with a general structural rolled steel (SS equivalent product) due to the anticorrosion effect.

  Furthermore, the specific numerical values such as the dimensions mentioned above are merely examples, and can be appropriately changed according to the needs of the product specifications and the like.
