According to the disaster prevention guide, 140 sandbags and 40 steel piles are required per 10 m, and work by 20 people is required. Many sandbag bags are usually prepared in local warehouses, etc., and the bags are filled with soil when the rivers are flooded. In addition, the dam construction method is a construction method in which a wooden pile is driven along the river at the top of the dike and a board is passed over this to form a dam, and soil and sandbags are built inside to prevent overflow. According to the guide, 20 people per 10 m, 12 plates, and a considerable number of sandbags are required.

  However, the sandbag type construction method requires enormous human resources and takes time and effort. In addition, the dam construction method requires a large amount of personnel, labor and time for the transportation of materials such as heavy wooden boards and the construction of the dam. In fact, these operations must be carried out in heavy rain, which involves great effort and difficulty. In addition, after the danger has passed, the sandbag is torn and the soil inside is discharged, but the sandbag bag is basically discarded after being used once, which is costly and unfavorable to the environment.

In view of such a problem, the applicant of the present application developed a folding water overflow prevention device using a lightweight material and filed a patent application on April 5, 2005 (Patent Document 1).

  The best mode for carrying out the present invention will be described in detail below with reference to the drawings.

  FIG. 1 is a perspective view showing a structure of a water overflow prevention apparatus 1 constituting a water overflow prevention facility according to the present invention, FIG. 2 (a) is an elevation view thereof, and FIG. 2 (b) is a fixing anchor. It is a front view which shows the state which stabbed the pin. As shown in FIGS. 1 and 2, the water overflow prevention device 1 has a configuration in which a plurality of square frames 10 formed of four walls extending in the vertical direction are connected in series, and separates the frames 10. The side wall is configured to be shared between adjacent frames. Guide frames 11 for guiding the anchor pins 50 in the vertical direction are provided at the corners of each frame 10, and will be described in detail later. At both ends of the device 1, fasteners for connecting to other devices are provided. A member 12 is provided. A suspension belt 13 is provided in a loop shape at each corner of the frame 10 so as to straddle each corner. Further, a bottom sheet 14 having a length extending from the front lower end portion of the device 1 to the entire lengthwise direction of the device and a width to the middle portion in the front-rear direction extends. The height of the device is 0.4 to 1.0 m, the width in the front-rear direction is 0.6 to 1.5 m, and the length in the horizontal direction of each frame 10 is 0.4 to 1.5 m (the length of the entire device). 2 to 7.5 m). In the following description, the front side of the paper surface in FIG. 1 will be described as the front side of the river (side facing the river or water) and will be described as the front side, and the back side will be described as the back side of the river.

  In the frame 10, the configuration of the vertical frame 15 extending in the front-rear direction of the device 1 will be described with reference to FIG. 3. The vertical frame 15 of the present embodiment is configured, for example, by attaching sheet materials 17 to both sides of a panel material 16 having strength. The panel material 16 can be made of a light and strong resin material such as vinyl chloride, FRP, acrylic, reinforced plastic, etc., preferably a recycled resin. The thickness of the panel material 16 is 5 to 30 mm to ensure strength. As the sheet material 17, for example, a soft, water-impermeable material having a predetermined strength such as polyethylene, vinyl chloride, polyurethane, polyester, and plastic rubber can be suitably used, and a recycled material is preferably used. However, the vertical frame 15 may be composed of only the panel material 16 without attaching the sheet material 17 together. In this case, it is desirable to use an impermeable material for the panel material 16.

  In the frame 10, the structure of the horizontal frame 18 extended in the left-right direction of the apparatus 1 is demonstrated with reference to FIG. The horizontal frame 18 of the present embodiment has a common configuration on the front side and the rear side, and sandwiches two panel members 19a and 19b having a width slightly less than half that of the frame 18 between the front and back sheet materials 20 one by one. It is configured. A slight gap is provided between the two panel members 19a and 19b so that they do not interfere with each other when the horizontal frame 18 is bent. The material of the panel material 19 and the sheet material 20 is the same as that of the vertical frame 15, and the sheet material 20 is bonded to the entire front and back surfaces of each panel material 19. Further, the sheet material 20 is formed to be slightly longer in the lateral direction than the panel material 19, and the surplus portion is connected to the vertical frame 18, the guide band 11, the fastener member 12, and the like by means such as sewing or adhesion. Yes. As a result, the horizontal frame 18 can be folded and overlapped at the center thereof, and the joint between the vertical frame 15 and the horizontal frame 18 is movable.

  As shown in FIG. 1, the bottom sheet 14 has at least a length over the entire lateral direction of the device 1 and a width to an intermediate portion in the front-rear direction of the device 1. The bottom sheet 14 is not connected to the vertical frame 15, and continuously extends from the lower end of the horizontal frame 18 on the front side of each frame 10. The bottom sheet 14 is used by being folded so as to form a part of the bottom portion of the apparatus 1 inside, that is, the apparatus 1 when the overflow prevention apparatus 1 is installed. The bottom sheet 14 is a soft water-impermeable material, and can be made of the same material as the sheet materials 17 and 20, for example. The width | variety (length from the lower end part of the horizontal frame 18 to a free edge) of the front-back direction of the bottom sheet | seat 14 is formed in about 0.3-1.0m.

  As shown in FIG. 1, the overflow apparatus 1 according to the present embodiment extends a sheet material 20 by extending the panel material 19 shown in FIG. And a fastener member 12 is provided on the edge of the cover. The fastener member 12 is, for example, a slide fastener that moves the slider to engage the left and right engaging teeth (elements). By arranging the water overflow prevention devices 1 shown in FIG. 1 and engaging the corresponding fastener members 12, It is comprised so that an apparatus can be connected. As shown in FIG. 1, the fastener member 12 is on the river back side (side not facing water) from the upper end to the lower end of the apparatus 1 on the river front side (side facing water and having the bottom sheet 14). ) Is provided so as to extend from the upper end portion of the apparatus 1 to the intermediate portion of the bottom sheet 14 through the lower end portion. Thus, since the fastener member 12 is extended about 15 cm from the lower side of the apparatus 1 to the bottom sheet 14 side, the bottom part of the connection part between apparatuses can be shielded suitably and water can be prevented from entering.

  The connection structure of the fastener member 12 will be described with reference to FIG. FIG. 5A is a view for explaining the fastener member 12 on the river back side in particular, and as shown in this figure, the fastener members 12a and 12b at the ends of the two overflow prevention devices 1 are brought close to each other. The upper end engages with the slider, and the slider is pulled down to the lower end of the apparatus. Note that the upper end portion of the fastener member 12 extends slightly above the upper end portion of the apparatus frame 10 so as to ensure the flexibility of the first meshing portion.

  On the other hand, the fastener member 12 extends beyond the lower end portion of the apparatus frame 10 to the middle portion of the bottom sheet 14 as shown in FIG. The gap with the ground is not generated. Further, an address cloth 35 that protects the fastener member 12 when connected is attached to the vicinity of the end of the bottom sheet 14 of one apparatus, and after the apparatus 1 is connected, the address cloth 35 is attached to the bottom fastener member 12. Overlaid. Accordingly, the engagement teeth and the slider of the fastener member 12 are protected from deformation and damage from the impact and weight when the soil or sandbag is stacked on the bottom sheet 14.

  The fastener member 12 is preferably made of a recyclable resin material and is highly waterproof. However, the fastener member 12 is not limited to this example, and does not exclude being made of various materials such as metal. Further, instead of a slide fastener, a rail fastener that opens and closes a resin rail with a slider, a Velcro fastener as a surface fastener, and a snap button as a point fastener may be used. These devices can be connected while the device 1 is placed on the ground, and can be joined easily and reliably because there is no need to lift the device. In addition, since the fastener member 12 can be attached to the apparatus main body by sewing or bonding, the apparatus can be easily manufactured, and the entire apparatus can be made of resin or plastic, so that disposal and recycling are easy.

  Returning to FIG. 1, the guide band 11 is formed at the corner of each frame 10 by forming the same sheet material as the sheet materials 17 and 20 into a cylindrical shape. The device 1 can be fixed by passing a pile (anchor pin 50) through the guide belt 11 from above and driving it into the ground.

  The suspension belt 13 is attached in a loop shape that straddles each corner of the frame body 10. The suspension belt 13 is connected to the frame 10 by means such as sewing, adhesion, or rivet using a strong and high-strength cloth material such as nylon. The suspension belt 13 is provided so that when the device is removed, the suspension belt 13 is lifted by a heavy machine such as a crane through a wire or the like, and the soil or sandbag inside the device 1 can be easily discharged from below. If the suspension belt 13 is constituted by a cloth-like member instead of a metal hook or the like, the entire apparatus 1 is constituted by a resin / plastic material, and separation and recycling at the time of disposal are greatly facilitated. The connecting portion between the suspension belt 13 and the apparatus main body may extend long from the upper end to the lower end of the apparatus 1. Thereby, the load at the time of lifting an apparatus is distributed and durability improves.

  In the water overflow prevention device 1 configured as described above, each frame 10 is formed after the bottom sheet 14 is folded outward from the state shown in FIG. 1, as in the above-described prior art document 1 (Japanese Patent Laid-Open No. 2006-283505). The horizontal panel 18 can be folded in a small size by being folded from the left and right sides while being folded inward. The device 1 can be transported in a folded state, and can be suitably stored in a warehouse or the like during normal times.

  Further, when danger such as heavy rain, flood, tsunami, etc. occurs, the device 1 is transported to a necessary place in a folded state, and is expanded and installed in the reverse order. The apparatus 1 can be applied to various places where sandbags are conventionally stacked to prevent water overflow, such as on rivers or coastal dikes. FIG. 6 is a cross-sectional image diagram showing a state in which the present apparatus 1 is installed at the top of a river dike, where the left side of the page is the river front side and the right side is the river back side. As shown in the figure, the present apparatus 1 is installed at a distance of about 1 m from the river front side at the top of the dike. At this time, the bottom sheet 14 extends inward so as to form a part of the bottom of the apparatus 1.

  Next, for example, an anchor pin 50 as shown in FIG. 7 is driven into each guide band 11 through a washer. The anchor pin 50 has a length of about 0.8 to 2.1 m and a pile diameter of about 16 to 50 mm, and extends about 0.4 to 1.0 m below the device 1 when driven. The pile head shape of the anchor pin 50 is configured in a round shape, an inverted triangle shape, an L shape, a T shape, etc. as shown in FIG. 7, and is easy to drive when installing the device 1 and easy to remove when removed. Use. For example, when the device 1 is installed on concrete, it is not an indispensable procedure to drive the guide belt 11 through a pile into the ground, but only by installing the device 1 and stacking sand and sandbags in the frame 10. Good.

  Further, a plurality of devices 1 are connected as necessary. As described above, the overflow prevention device 1 of the present invention can be easily and quickly connected by arranging the fasteners and connecting the fastener members. Thereafter, earth and sand are introduced into the apparatus 1. In this work, the soil is transported by a dump truck or the like, and the earth and sand are put into the apparatus 1 by a backhoe or human power. At this time, the bottom sheet 14 partially extends to the bottom of the apparatus 1, and by putting earth and sand on the bottom sheet 14, the soft bottom sheet 14 comes into close contact with the ground below to close the gap. Intrusion of water from the lower side of 1 is prevented. Instead of this earth and sand, sandbags and other heavy objects may be arranged inside the apparatus 1. In the case of a sandbag, it is arranged on the bottom sheet 14 so that there is no gap in the length direction. In the case of other heavy objects, the ones transported by human power or machines should be arranged as necessary. In the present invention, water overflow can be reliably prevented with a much smaller number of sandbags than the water overflow prevention method in which sandbags are stacked without using the apparatus 1.

  After the water level has dropped and the danger has passed, the overflow prevention device 1 is removed. In this operation, after the anchor pin 50 is removed, the suspension belt 13 of the device 1 is pulled by a crane truck or human power to lift the entire device 1 upward. As a result, the bottom sheet 14 continuous with the front side frame 18 of the apparatus 1 is pulled upward, and the apparatus 1 is lifted while the load on the bottom sheet 14 remains on the ground. Thereafter, the apparatus 1 is washed, folded and stored again. In this way, the overflow prevention equipment of the present invention can be used repeatedly.

  FIG. 8 is a diagram showing a configuration of another embodiment of the panel material constituting the frame body 10. In the above embodiment, the front and rear horizontal frames 18 are constituted by two panel members 19a and 19b and a sheet member 20 sandwiching the panel members 19a and 19b. For example, as shown in FIG. Only the horizontal frame 31 may be configured in this way to ensure strength, and the rear horizontal frame 32 may be configured only by a sheet material. Further, when the sheet material has sufficient strength, both the front and rear horizontal frames may be composed of only the sheet material as shown in FIG. Even in this case, if the vertical frame 15 is configured using a panel material, the strength of the apparatus is maintained at a high level, and water overflow can be reliably prevented. Further, when a panel material is used for the horizontal frame, the sheet material does not need to cover the entire surface of the panel material, and may be provided only at the junction between the panel materials 19 a and 19 b and the junction between the vertical frame 15. .

  9 and 10 are diagrams for explaining a second embodiment of the overflow prevention facility of the present invention.

As shown in this figure, the joining member 37 cuts the panel material 16 or 19 shown in FIG. 3 or FIG. 4 with a desired width, covers this with the sheet material 17 or 20, and fastener members 12a, 12b is attached to each. The fastener members 12a and 12b at both ends of the joining member 37 are the same as the fastener members 12a and 12b at both ends of the water overflow preventing member 1, respectively, and if these are adjacent and meshed with a slider, as shown in FIG. The members are connected to each other. In addition, FIG. 10A is a joining member 37 connected to the river surface side, which itself has a bottom sheet 38 having a length corresponding to the bottom sheet 14 of the water overflow prevention device 1, and the fastener member 12 is It extends to the middle part of the bottom sheet 38. FIG. 10B is a joining member connected to the river back side, and the fastener member 12 extends to the upper and lower ends without having a bottom sheet.

  In this manner, by installing the joining member 37 in the connecting portion of the water overflow prevention device 1 as necessary, the water overflow prevention equipment can be freely installed in a curved line. In addition, the width | variety of the joining member 37 can prepare an appropriate thing according to necessity and usability, for example, 5-200 cm. Alternatively, a relatively wide joint member 37 may be configured by connecting two or more joint members 37 in series at the same location.
