It is a front view of the same submersion prevention structure. 5 is a cross-sectional view taken along line CC of FIG. 4; FIG.

Next, specific embodiments of the present invention will be described with reference to the attached drawings for better understanding of the present invention.
The submersion prevention structure 10 according to the first embodiment of the present invention shown in FIGS. It is intended to protect an object 12 to be protected, such as a large-sized mechanical facility that is too heavy to be transported or moved, from being submerged in water.
The submersion prevention structure 10 includes a plurality of fasteners (here, anchor nuts) 13 (see FIG. 3) embedded in the installation surface 11 around the outer periphery of the object 12 to be protected, and the installation surface 11 via the fasteners 13. and a water submersion prevention cover 15 detachably fixed to. The submersion prevention cover 15 is made of a waterproof material and includes a peripheral wall portion 16 that covers the outer circumference of the object to be protected 12, a collar portion 17 that extends along the entire periphery of the lower end of the peripheral wall portion 16, and an upper surface 18 of the object to be protected 12. It has a ceiling part 19 covering the . The submergence prevention structure 10 includes a water stop material 20 (see FIG. 3) arranged along the entire circumference of the flange 17 between the installation surface 11 and the bottom surface of the flange 17, and placed on the upper surface of the flange 17. and a plurality of fasteners (here, bolts) 22 that pass through the retaining member 21 , the collar portion 17 and the water stop material 20 and are fastened to the fasteners 13 .

As a waterproof material forming the submersion prevention cover, it is preferable to use a fabric having robustness and durability similar to those of rubber boats, disaster air tents, fireproof protective clothing, and the like. In particular, the fabric for rubber boats used on water is suitable because it is resistant to tearing and has excellent watertightness. Specifically, a rubber-coated fabric obtained by laminating multiple layers of rubber such as chlorosulfonated polyethylene rubber, ethylene propylene diene rubber, chloroprene rubber, or natural rubber to a synthetic fiber base fabric such as polyamide or polyester is preferably used. be done. When polyamide is used as the base fabric, it is lightweight and has excellent flexibility and stretchability. When polyester is used, it is hard, highly rigid, has little stretchability, and is excellent in durability. The combination and the number of layers of rubber to be attached to the base fabric can be selected as appropriate. Also, instead of rubber, a fabric obtained by laminating a vinyl chloride resin to a base fabric may be used. The submersion prevention cover only needs to cover the entire object to be protected, and the shape and size of the peripheral wall and ceiling can be appropriately selected according to the shape and size of the object to be protected.

The width of the flange is preferably, for example, about 100 to 300 mm, but is not limited to this range and can be appropriately selected according to the size of the object to be protected.
In this embodiment, the fasteners 13 are arranged in a row around the object 12 to be protected, but the number and arrangement of the fasteners can be selected as appropriate. The arrangement interval of the fasteners is preferably, for example, about 200 to 500 mm, but is not limited to this range, and can be appropriately selected according to the size of the object to be protected. good. Alternatively, the fasteners may be arranged in two rows, in which case the first row and the second row may be staggered (staggered) by shifting them in the pitch direction.
In the present embodiment, the peripheral wall portion 16 and the flange portion 17 are integrally (seamlessly) formed. can be ensured. Further, in the present embodiment, the outer periphery of the ceiling portion 19 and the upper end portion of the peripheral wall portion 16 are adhered by welding and connected watertightly, but the ceiling portion and the peripheral wall portion are integrally (seamlessly) to the extent possible. may be formed. When seams between peripheral wall portions, seams between flange portions, seams between peripheral wall portions and flange portions, and seams between peripheral wall portions and ceiling portions occur, the number and locations thereof can be appropriately selected, and the seams are welded. Alternatively, instead of sticking them together by adhesion, they can be connected with a waterproof (waterproof) fastener.

In this embodiment, the water-swelling rubber that expands by absorbing water is used as the water-stopping material 20 . As a result, when water enters around the submergence prevention cover 15, the water stop material 20 expands to reliably close the gap between the installation surface 11 and the bottom surface of the flange 17, thereby preventing water from entering the submergence prevention cover 15. can be prevented. Note that the water stop material is not limited to this, and any material that can stop water between the installation surface 11 and the bottom surface of the flange portion 17 may be used. In addition, the water stop material needs to be arranged continuously without gaps over the entire circumference of the collar, and is preferably formed in a single annular shape according to the shape of the collar. Plate-shaped water stop materials may be arranged continuously along the flange. Furthermore, after arranging the water stop material on the installation surface, a submersion prevention cover may be placed and the upper surface of the water stop material may be covered with the flange. By placing the submersion prevention cover on the installation surface, it is possible to prevent the positional displacement of the water stop material, and the workability is excellent. In addition, when temporarily fixing the waterproof material to the brim via the adhesive layer, if the adhesive layer is not formed over the entire width of the waterproof material but is partially formed, the adhesive layer is compressed, the water-stopping material around the adhesive layer swells, and the flange portion is brought into close contact with the adhesive layer, thereby preventing water from entering the interior of the submersion prevention cover from the adhesive layer. In particular, if unevenness is provided on the surface of the water-stopping material and an adhesive layer is formed in the recessed portions, the water-stopping material around the adhesive layer can be reliably brought into close contact with the flange.

As the pressing member 21, a long plate material (e.g., flat bar) made of metal such as stainless steel is preferably used, but it is not limited thereto, and the fastener 13 and fastener 22 are fastened. Therefore, it is sufficient that the water stop material 20 can be compressed by pressing the collar portion 17 against the installation surface 11 side. In this embodiment, the entire length of each pressing member 21 is formed substantially equal to the length of each side of the collar portion 17, and the pressing member 21 is arranged over substantially the entire circumference of the collar portion 17. The holding members can be intermittently arranged within a range that can ensure the length, number and arrangement interval of each holding member in that case can be appropriately selected. Further, the width of the pressing member is preferably 50 to 200 mm, but is not limited to this range, and can be appropriately selected within a range equal to or less than the width of the flange. Although the thickness of the pressing member is preferably 3 to 15 mm, the thickness is not limited to this range, and can be appropriately selected according to the area of the pressing member.
Through-holes 24 , 25 , and 26 through which fasteners 22 are inserted are formed in the pressing member 21 , the collar portion 17 , and the waterproof material 20 , corresponding to the positions of the fasteners 13 . Thereby, positioning between each member can be performed easily, and it is excellent in workability. Even if these through holes 24, 25, and 26 are formed, the lower surface and upper surface of the water stop material 20 are in close contact with the installation surface 11 and the bottom surface of the flange 17 around the through hole 26, respectively. Water does not enter the submergence prevention cover 15 through the through holes 24 , 25 , 26 . In particular, when water-swelling rubber is used as the water-swelling material, the gap between the inner peripheral surface of the through-hole 26 and the outer peripheral surface of the fastener 22 is filled by the swelling of the water-swelling material (water-swelling rubber), and the through-hole Entry of water into 26 can be more reliably prevented.

According to the above configuration, in preparation for the occurrence of a tsunami, flood, etc., the water stop material 20 and the submergence prevention cover 15 (flange) are placed on the fastener 13 embedded in the installation surface 11 on the outer periphery of the object 12 to be protected in advance. 17), and the pressing member 21 are arranged in this order, and the fastener 22 is fastened to the fastening member 13, and the water stop material 20 and the brim portion 17 of the submergence prevention cover 15 are compressed between the installation surface 11 and the pressing member 21. By fixing the submersion prevention cover 15 in such a manner, the outer periphery of the object to be protected 12 can be stopped from water, and even if the surroundings of the object to be protected 12 are flooded, water will enter the inside of the submersion prevention cover 15. It is possible to prevent the object to be protected 15 from being submerged.

Next, a submersion prevention structure 28 according to a second embodiment of the present invention will be described with reference to FIGS. 4 to 6. FIG. It should be noted that the same reference numerals are given to the same configurations as in the first embodiment, and the description thereof will be omitted.
The submergence prevention structure 28 differs from the submergence prevention structure 10 in that the submergence prevention cover 29 does not have a ceiling, and is attached to the upper part of the peripheral wall 16 and rises as the surrounding water level rises. 16 is provided with a buoyancy generator 30 that pulls up the upper part. The buoyancy generator 30 is formed in the shape of a hollow bag and attached to the entire circumference of the peripheral wall 16, and is filled with gas (air, nitrogen, carbon dioxide, etc.) during use. As a result, even if the peripheral wall portion 16 is installed in a state of being crushed in the height direction at the start of use (before submersion), the buoyancy generating portion 30 will lift the upper portion of the peripheral wall portion 16 as the surrounding water level rises during flooding. can be moved upward, and as long as the water level does not exceed the maximum height of the peripheral wall portion 16, it is possible to prevent water from entering the interior of the submersion prevention cover 29 and prevent the object to be protected 12 from being submerged. can. Therefore, if the peripheral wall 16 is formed higher than the assumed water level at the time of flooding, regardless of the height of the object 12 to be protected (the peripheral wall 16 covers the lower outer periphery of the object 12 to be protected). ), it can protect the protected object 12 from being submerged in water, and is excellent in versatility.

In addition, the peripheral wall portion 16 and the flange portion 17 are formed in a strip shape and are wound along the outer periphery of the object to be protected 12 so that both ends of the peripheral wall portion 16 and the flange portion 17 in the longitudinal direction are watertight. , the submersion prevention cover 29 is arranged along the outer periphery of the protection object 12 with the peripheral wall portion 16 being crushed in the height direction even if the protection object 12 is high. Moreover, both longitudinal ends of the peripheral wall portion 16 and the flange portion 17 can be easily connected on the ground, and there is no need to perform connection work using a stepladder or the like, which improves safety and workability. Excellent. Therefore, as shown in FIGS. 4 and 5, by attaching a waterproof fastener 31 along the height direction of the peripheral wall portion 16 and the width direction of the flange portion 17, the peripheral wall portion 16 and the flange portion 17 formed in a belt shape can be Both ends in the longitudinal direction can be easily and reliably watertightly connected. In addition, the position of the waterproof fastener can be appropriately selected. Also, a submersion prevention cover can be configured by connecting a plurality of belt-shaped peripheral wall portions and collar portions via a waterproof fastener. In this case, the submersion prevention cover can be easily increased in size by appropriately connecting (adding) the peripheral wall portion and the collar portion formed in a belt shape with a predetermined length, and is excellent in versatility.

When the peripheral wall portion 16 and the flange portion 17 are formed in a strip shape, the buoyancy generating portion 30 is detachable from the peripheral wall portion 16, and the peripheral wall portion 16 and the flange portion 17 are wound along the outer periphery of the object to be protected 12 to form an edge. The buoyancy generator 30 may be attached after the sections are connected, or instead of the annular buoyancy generator, a rod-shaped buoyancy generator may be attached along the longitudinal direction of the strip-shaped peripheral wall. Alternatively, a plurality of buoyancy generators may be divided and attached along the circumferential direction of the peripheral wall. As shown in FIG. 6, if the connecting position between the peripheral wall portion 16 and the buoyancy generating section 30 is higher than the bottom position of the buoyancy generating section 30, the water level will rise above the connecting position while the buoyancy generating section 30 is floating on the water. Therefore, the joint surface between the peripheral wall portion 16 and the buoyancy generating portion 30 does not need to be watertight, and the two can be easily connected (joined) using a hook-and-loop fastener or the like. Water-tight connections can also be made using water fasteners. It can also be applied to objects to be protected to which wires and pipes are connected from the ceiling of a building, and is excellent in flexibility of installation.

Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations described in the above embodiments, and can be considered within the scope of the matters described in the claims. Other embodiments and modifications are also included.
For example, in the above-described embodiment, the peripheral wall portion of the submersion prevention cover is formed in a square tubular shape (rectangular shape when viewed from the top), but the peripheral wall portion only needs to be able to cover the outer circumference of the object to be protected. It may be formed in a circular shape in plan view).
In addition, the number of objects to be protected to be protected by one submersion prevention cover can be appropriately selected, and multiple objects to be protected that are placed close to each other or multiple objects to be protected that are connected by wiring or piping can be combined into one. A single submergence prevention cover may be used to protect the entire building, or a submergence prevention cover having a ceiling can be installed outdoors, and the entire building can be protected from submersion as a protected object.
Furthermore, a buffer member is attached to the outer circumference of the submergence prevention cover (peripheral wall) to reduce the impact of a collision with drifting objects, etc., and to prevent damage to the peripheral wall. As the cushioning member, a hollow bag-like member that can be filled with a gas (air, nitrogen, carbon dioxide, etc.) (for example, an air mat) is preferably used, but is not limited thereto. Its material and structure can be selected as appropriate. In addition, if necessary, reinforcing members may be attached to key points on the inside and/or outside of the peripheral wall.
In the above-described embodiment, anchor nuts and bolts are used as the fasteners and fasteners, but it is also possible to embed anchor bolts as the fasteners in the installation surface and use nuts as the fasteners. Further, the fastener and the fastener are not limited to a combination of a bolt and a nut as long as they can compress the water stop material by pressing the pressing member against the installation surface. In particular, when the water-swelling rubber is used as the water-swelling rubber, it is sufficient that the fastener and the fastener can maintain the fastened state even if the water-swelling rubber absorbs water and expands. It may be fastened by joining (friction).
Objects to be protected include automatic ticket gates of trains, subways, and the like.

Next, specific embodiments of the present invention will be described with reference to the attached drawings for better understanding of the present invention.
The submersion prevention structure 10 according to the first embodiment of the present invention shown in FIGS. It is intended to protect an object 12 to be protected, such as a large-sized mechanical facility that is too heavy to be transported or moved, from being submerged in water.
The submersion prevention structure 10 includes a plurality of fasteners (here, anchor nuts) 13 (see FIG. 3) embedded in the installation surface 11 around the outer periphery of the object 12 to be protected, and the installation surface 11 via the fasteners 13. and a water submersion prevention cover 15 detachably fixed to. The submersion prevention cover 15 is made of a waterproof material and includes a peripheral wall portion 16 that covers the outer circumference of the object to be protected 12, a collar portion 17 that extends along the entire periphery of the lower end of the peripheral wall portion 16, and an upper surface 18 of the object to be protected 12. It has a ceiling part 19 covering the . The submergence prevention structure 10 includes a water stop material 20 (see FIG. 3) arranged along the entire circumference of the flange 17 between the installation surface 11 and the bottom surface of the flange 17, and placed on the upper surface of the flange 17. and a plurality of fasteners (here, bolts) 22 that pass through the retaining member 21 , the collar portion 17 and the water stop material 20 and are fastened to the fasteners 13 .

As a waterproof material forming the submersion prevention cover, it is preferable to use a fabric having robustness and durability similar to those of rubber boats, disaster air tents, fireproof protective clothing, and the like. In particular, the fabric for rubber boats used on water is suitable because it is resistant to tearing and has excellent watertightness. Specifically, a rubber-coated fabric obtained by laminating multiple layers of rubber such as chlorosulfonated polyethylene rubber, ethylene propylene diene rubber, chloroprene rubber, or natural rubber to a synthetic fiber base fabric such as polyamide or polyester is preferably used. be done. When polyamide is used as the base fabric, it is lightweight and has excellent flexibility and stretchability. When polyester is used, it is hard, highly rigid, has little stretchability, and is excellent in durability. The combination and the number of layers of rubber to be attached to the base fabric can be selected as appropriate. Also, instead of rubber, a fabric obtained by laminating a vinyl chloride resin to a base fabric may be used. The submersion prevention cover only needs to cover the entire object to be protected, and the shape and size of the peripheral wall and ceiling can be appropriately selected according to the shape and size of the object to be protected.

The width of the flange is preferably, for example, about 100 to 300 mm, but is not limited to this range and can be appropriately selected according to the size of the object to be protected.
In this embodiment, the fasteners 13 are arranged in a row around the object 12 to be protected, but the number and arrangement of the fasteners can be selected as appropriate. The arrangement interval of the fasteners is preferably, for example, about 200 to 500 mm, but is not limited to this range, and can be appropriately selected according to the size of the object to be protected. good. Alternatively, the fasteners may be arranged in two rows, in which case the first row and the second row may be staggered (staggered) by shifting them in the pitch direction.
In the present embodiment, the peripheral wall portion 16 and the flange portion 17 are integrally (seamlessly) formed. can be ensured. Further, in the present embodiment, the outer periphery of the ceiling portion 19 and the upper end portion of the peripheral wall portion 16 are adhered by welding and connected watertightly, but the ceiling portion and the peripheral wall portion are integrally (seamlessly) to the extent possible. may be formed. When seams between peripheral wall portions, seams between flange portions, seams between peripheral wall portions and flange portions, and seams between peripheral wall portions and ceiling portions occur, the number and locations thereof can be appropriately selected, and the seams are welded. Alternatively, instead of sticking them together by adhesion, they can be connected with a waterproof (waterproof) fastener.

In this embodiment, the water-swelling rubber that expands by absorbing water is used as the water-stopping material 20 . As a result, when water enters around the submergence prevention cover 15, the water stop material 20 expands to reliably close the gap between the installation surface 11 and the bottom surface of the flange 17, thereby preventing water from entering the submergence prevention cover 15. can be prevented. Note that the water stop material is not limited to this, and any material that can stop water between the installation surface 11 and the bottom surface of the flange portion 17 may be used. In addition, the water stop material needs to be arranged continuously without gaps over the entire circumference of the collar, and is preferably formed in a single annular shape according to the shape of the collar. Plate-shaped water stop materials may be arranged continuously along the flange. Furthermore, after arranging the water stop material on the installation surface, a submersion prevention cover may be placed and the upper surface of the water stop material may be covered with the flange. By placing the submersion prevention cover on the installation surface, it is possible to prevent the positional displacement of the water stop material, and the workability is excellent. In addition, when temporarily fixing the waterproof material to the brim via the adhesive layer, if the adhesive layer is not formed over the entire width of the waterproof material but is partially formed, the adhesive layer is compressed, the water-stopping material around the adhesive layer swells, and the flange portion is brought into close contact with the adhesive layer, thereby preventing water from entering the interior of the submersion prevention cover from the adhesive layer. In particular, if unevenness is provided on the surface of the water-stopping material and an adhesive layer is formed in the recessed portions, the water-stopping material around the adhesive layer can be reliably brought into close contact with the flange.

As the pressing member 21, a long plate material (e.g., flat bar) made of metal such as stainless steel is preferably used, but it is not limited thereto, and the fastener 13 and the fastener 22 are fastened. Therefore, it is sufficient that the water stop material 20 can be compressed by pressing the collar portion 17 against the installation surface 11 side. In this embodiment, the entire length of each pressing member 21 is formed substantially equal to the length of each side of the collar portion 17, and the pressing member 21 is arranged over substantially the entire circumference of the collar portion 17. The holding members can be intermittently arranged within a range that can ensure the length, number and arrangement interval of each holding member in that case can be appropriately selected. Further, the width of the pressing member is preferably 50 to 200 mm, but is not limited to this range, and can be appropriately selected within a range equal to or less than the width of the flange. Although the thickness of the pressing member is preferably 3 to 15 mm, the thickness is not limited to this range, and can be appropriately selected according to the area of the pressing member.
Through-holes 24 , 25 , and 26 through which fasteners 22 are inserted are formed in the pressing member 21 , the collar portion 17 , and the waterproof material 20 , corresponding to the positions of the fasteners 13 . Thereby, positioning between each member can be performed easily, and it is excellent in workability. Even if these through holes 24, 25, and 26 are formed, the lower surface and upper surface of the water stop material 20 are in close contact with the installation surface 11 and the bottom surface of the flange 17 around the through hole 26, respectively. Water does not enter the submergence prevention cover 15 through the through holes 24 , 25 , 26 . In particular, when water-swelling rubber is used as the water-swelling material, the gap between the inner peripheral surface of the through-hole 26 and the outer peripheral surface of the fastener 22 is filled by the swelling of the water-swelling material (water-swelling rubber), and the through-hole Entry of water into 26 can be more reliably prevented.

According to the above configuration, in preparation for the occurrence of a tsunami, flood, etc., the water stop material 20 and the submergence prevention cover 15 (flange) are placed on the fastener 13 embedded in the installation surface 11 on the outer periphery of the object 12 to be protected in advance. 17), and the pressing member 21 are arranged in this order, and the fastener 22 is fastened to the fastening member 13, and the water stop material 20 and the brim portion 17 of the submergence prevention cover 15 are compressed between the installation surface 11 and the pressing member 21. By fixing the submersion prevention cover 15 in such a manner, the outer periphery of the object to be protected 12 can be stopped from water, and even if the surroundings of the object to be protected 12 are flooded, water will enter the inside of the submersion prevention cover 15. It is possible to prevent the object to be protected 12 from being submerged.

Next, a submersion prevention structure 28 according to a second embodiment of the present invention will be described with reference to FIGS. 4 to 6. FIG. It should be noted that the same reference numerals are given to the same configurations as in the first embodiment, and the description thereof will be omitted.
The submergence prevention structure 28 differs from the submergence prevention structure 10 in that the submergence prevention cover 29 does not have a ceiling, and is attached to the upper part of the peripheral wall 16 and rises as the surrounding water level rises. 16 is provided with a buoyancy generator 30 that pulls up the upper part. The buoyancy generator 30 is formed in the shape of a hollow bag and attached to the entire circumference of the peripheral wall 16, and is filled with gas (air, nitrogen, carbon dioxide, etc.) during use. As a result, even if the peripheral wall portion 16 is installed in a state of being crushed in the height direction at the start of use (before submersion), the buoyancy generating portion 30 will lift the upper portion of the peripheral wall portion 16 as the surrounding water level rises during flooding. can be moved upward, and as long as the water level does not exceed the maximum height of the peripheral wall portion 16, it is possible to prevent water from entering the interior of the submersion prevention cover 29 and prevent the object to be protected 12 from being submerged. can. Therefore, if the peripheral wall 16 is formed higher than the assumed water level at the time of flooding, regardless of the height of the object 12 to be protected (the peripheral wall 16 covers the lower outer periphery of the object 12 to be protected). ), it can protect the protected object 12 from being submerged in water, and is excellent in versatility.

In addition, the peripheral wall portion 16 and the flange portion 17 are formed in a strip shape and are wound along the outer periphery of the object to be protected 12 so that both ends of the peripheral wall portion 16 and the flange portion 17 in the longitudinal direction are watertight. , the submersion prevention cover 29 is arranged along the outer periphery of the protection object 12 with the peripheral wall portion 16 being crushed in the height direction even if the protection object 12 is high. Moreover, both longitudinal ends of the peripheral wall portion 16 and the flange portion 17 can be easily connected on the ground, and there is no need to perform connection work using a stepladder or the like, which improves safety and workability. Excellent. Therefore, as shown in FIGS. 4 and 5, by attaching a waterproof fastener 31 along the height direction of the peripheral wall portion 16 and the width direction of the flange portion 17, the peripheral wall portion 16 and the flange portion 17 formed in a belt shape can be Both ends in the longitudinal direction can be easily and reliably watertightly connected. In addition, the position of the waterproof fastener can be appropriately selected. Also, a submersion prevention cover can be configured by connecting a plurality of belt-shaped peripheral wall portions and collar portions via a waterproof fastener. In this case, the submersion prevention cover can be easily increased in size by appropriately connecting (adding) the peripheral wall portion and the collar portion formed in a belt shape with a predetermined length, and is excellent in versatility.

When the peripheral wall portion 16 and the flange portion 17 are formed in a strip shape, the buoyancy generating portion 30 is detachable from the peripheral wall portion 16, and the peripheral wall portion 16 and the flange portion 17 are wound along the outer periphery of the object to be protected 12 to form an edge. The buoyancy generator 30 may be attached after the sections are connected, or instead of the annular buoyancy generator, a rod-shaped buoyancy generator may be attached along the longitudinal direction of the strip-shaped peripheral wall. Alternatively, a plurality of buoyancy generators may be divided and attached along the circumferential direction of the peripheral wall. As shown in FIG. 6, if the connecting position between the peripheral wall portion 16 and the buoyancy generating section 30 is higher than the bottom position of the buoyancy generating section 30, the water level will rise above the connecting position while the buoyancy generating section 30 is floating on the water. Therefore, the joint surface between the peripheral wall portion 16 and the buoyancy generating portion 30 does not need to be watertight, and the two can be easily connected (joined) using a hook-and-loop fastener or the like. Water-tight connections can also be made using water fasteners. It can also be applied to objects to be protected to which wires and pipes are connected from the ceiling of a building, and is excellent in flexibility of installation.

It may be formed in a circular shape in plan view).
In addition, the number of objects to be protected to be protected by one submersion prevention cover can be appropriately selected, and multiple objects to be protected that are placed close to each other or multiple objects to be protected that are connected by wiring or piping can be combined into one. A single submergence prevention cover may be used to protect the entire building, or a submergence prevention cover having a ceiling can be installed outdoors, and the entire building can be protected from submersion as a protected object.
Furthermore, a buffer member is attached to the outer circumference of the submergence prevention cover (peripheral wall) to reduce the impact of a collision with drifting objects, etc., and to prevent damage to the peripheral wall. As the cushioning member, a hollow bag-like member that can be filled with a gas (air, nitrogen, carbon dioxide, etc.) (for example, an air mat) is preferably used, but is not limited thereto. Its material and structure can be selected as appropriate. In addition, if necessary, reinforcing members may be attached to key points on the inside and/or outside of the peripheral wall.
In the above embodiment, anchor nuts and bolts are used as the fasteners and fasteners, but it is also possible to embed anchor bolts as the fasteners in the installation surface and use nuts as the fasteners.
