Summary of the Invention
Problems to be Solved by the Invention
[0005] [[ID=S7]]The rescue techniques described in Patent Documents 1 to 3 using a net material include the following problems. <1> The netting materials described in Patent Documents 1 and 2 cling to the slope, making it difficult for victims' hands and feet to get caught, and thus difficult for them to climb the slope and escape. <2> In the concrete mat with rescue ropes described in Patent Document 3, the multiple rescue ropes are separated, making it difficult to transfer between them. Furthermore, the uneven surface of the concrete mat makes it difficult to trip over the ropes.
[0006] The life-saving facility made of concrete mats described in Patent Document 4 has the following problems. <1> Simply using a fabric mold made by overlapping two pieces of fabric is insufficient to form large protrusions. Therefore, in the invention of Patent Document 4, a portion of the upper fabric is cut to match the size of the protrusion, and a separate auxiliary bag for the protrusion is sewn into the opening created by the cut-out and attached integrally. Thus, in the invention described in Patent Document 4, the fabric opening work is performed to match the location of the protrusions, and auxiliary bags are attached to each opening, which means that the fabric formwork takes a lot of time and cost. <2> If the auxiliary bag described in Patent Document 4 is made of a rigid material, it is possible to form a projection with a rectangular cross-sectional shape that stands perpendicular to the mat body. However, because the auxiliary bags are made of soft fabric, they cannot support the weight of the mortar, and the height of the protrusions created by the auxiliary bags cannot be increased. As a result, the rescue platform still suffers from insufficient height, making it easy for victims to slip when climbing up on their own. <3> The concrete mat described in Patent Document 4 has limitations on the width of the auxiliary bags that can be formed, so it is not possible to form protrusions along the entire length of the concrete mat in the transverse direction, and therefore the protrusions are formed only on a part of the concrete mat in the transverse direction. Therefore, if the victim falls to a location far from where the protrusion was formed, the victim will expend energy moving towards the protrusion, hindering their escape.
[0007] The present invention aims to provide a rescue climbing structure that can solve the above-mentioned problems. [Means for solving the problem]
[0008] To solve the aforementioned problems, the present invention provides a rescue climbing structure comprising a bag-shaped fabric formwork having a formwork space inside, which is laid along a slope and has multiple points between the upper and lower fabrics partially connected with binding threads, and a solidifying material for constructing a mat structure by filling the formwork space of the fabric formwork in a slurry form, wherein the fabric formwork has multiple binding short threads and multiple binding long threads of different lengths between the upper and lower fabrics, and flattened Hei-shaped sections that form multiple protrusions on the surface of the mat structure, and raised higher than the protrusions on the surface side of the mat structure Thickened sections forming stepped protrusions are arranged alternately along the slope direction, and multiple connecting long threads connected at multiple locations between the upper and lower fabrics in the thickened sections are dimensionally longer than the total length of multiple connecting short threads connected at multiple locations between the upper and lower fabrics in the flattened sections, and multiple stepped protrusions formed in the thickened sections are formed continuously in the transverse direction of the slope, and the structure is configured to allow victims to climb through multiple protrusions and multiple stepped protrusions that are raised on the surface side of the mat structure. In another embodiment of the present invention, the stepped protrusion formed in the thickened section protrudes above the upper surface of the mat body formed in the flattened Hei section, and the width of the base of the stepped protrusion in the direction of inclination is greater than the width of the base of the protrusion formed in the flattened Hei section. In another embodiment of the present invention, multiple connecting short threads are connected in an X-shape or V-shape along the direction of the slope at multiple locations between the upper and lower fabrics located in the flattened Heisei-shaped section. In another embodiment of the present invention, the multiple protrusions formed in the flattened Hei-shaped section may be formed continuously in the transverse direction of the slope, or the multiple protrusions may be provided intermittently and arranged in a staggered pattern. In another embodiment of the present invention, multiple bonding sections, where multiple bonding short threads are connected at multiple locations between the upper and lower fabrics located in the flattened Hei-shaped section, and unbonded sections, where the bonding short threads are not connected, are arranged in a line along the direction of the slope, the fabric of the bonding sections is raised with a consolidating material to form protruding sections, and recessed grooves are formed in the unbonded sections between the protruding sections. In another embodiment of the present invention, multiple connecting long threads are connected in a V-shape or X-shape along the direction of the slope at multiple locations between the upper and lower fabrics located in the thickened molding section. In another embodiment of the present invention, multiple bonding sections, where multiple bonding long threads are connected at multiple locations between the upper and lower fabrics located in the thickened molding section, and unbonded sections, where the bonding short threads are not connected, are arranged in a line along the inclination direction of the slope, and the upper fabric of the bonding sections is raised with a consolidating material to form stepped protrusions. [Effects of the Invention]
[0009] The rescue climbing structure according to the present invention provides at least one of the following effects. <1> By using a fabric formwork connected between the upper and lower fabrics with multiple short and long threads of different lengths, it is possible to easily form multiple stepped protrusions with high elevations on the upper surface of the mat structure without having to add separate auxiliary bags afterward. <2> By connecting long threads to two points in the middle of the upper fabric located in the thickened molding section of the fabric formwork, the filling pressure of the slurry-like solidifying material filling the formwork space is locally applied to the top of the stepped protrusion, thereby increasing the height of the stepped protrusion. Because the stepped protrusions can be raised significantly higher than the top surface of the mat structure formed in the flattened Heisei-shaped section, it becomes easier for victims' hands and feet to get caught, and the probability of their escape increases dramatically. <3> By forming grooves in the valleys of the protruding sections of the flattened, elevated sections, not only the stepped protrusions but also the grooves can be used as gripping points for the victim's hands and feet, further increasing the probability of the victim's escape. <4>There is no need for any operation such as opening an opening in a part of the fabric of the fabric formwork or attaching a separate auxiliary bag to the opening, and the manufacturing time and manufacturing cost of the fabric formwork can be significantly reduced.

Embodiments for Carrying out the Invention
[0011] The rescue ramp structure according to the present invention will be described in detail below with reference to the drawings.
[0012] <1>Overview of the rescue ramp structure Referring to FIG. 1, the rescue ramp structure 10 is laid and used along the slope 51 of the retention pond 50. The retention pond 50 includes a retention pond, a regulating pond, a waterway, etc. The rescue ramp structure 10 according to the present invention is composed of a fabric formwork 20 manufactured by overlapping two upper and lower fabrics, and a solidifying material 40 such as mortar filled in the fabric formwork 20.
[0013] In the following explanation, we will define the vertical direction of the rescue climbing structure 10 or fabric formwork 20 in the same direction as the slope 51 as "Y", and the horizontal direction of the rescue climbing structure 10 or fabric formwork 20 in the same direction as the transverse direction of the slope 51 as "X".
[0014] <2> Fabric formwork In this invention, a fabric formwork 20 as described below is used.
[0015] The explanation will be given with reference to Figures 1 to 3. The fabric formwork 20 consists of a flexible upper fabric 21, a flexible lower fabric 22, and two types of connecting threads of different lengths (connecting short threads 31 and connecting long threads 32) that connect the two fabrics 21 and 22. The upper fabric 21 and the lower fabric 22 are made of, for example, a plain weave double fabric. A portion of the fabric formwork 20 has one or more injection ports for injecting the consolidating material 40.
[0016] The fabric formwork 20 has its edges closed in a bag-like manner on both sides of the fabric 21 and 22, forming a continuous formwork space 23 inside.
[0017] To describe in detail the fabric formwork 20 used in the present invention, the fabric formwork 20 comprises a flattened Hei-shaped section 20a for forming a thin mat body with an uneven surface shape, and a plurality of thickened molding sections 20b formed adjacent to the flattened Hei-shaped section 20a for partially raising the mat body to form stepped protrusions 13. These flattened Hei-shaped sections 20a and horizontally elongated thickened sections 20b are formed alternately along the vertical direction Y of the fabric formwork 20, and a communicating formwork space 23 is formed inside them.
[0018] <2.1> Fabric This will be explained with reference to Figures 4A and 5A. The upper fabric 21 and lower fabric 22 that make up the fabric formwork 20 can be made from fabrics woven as a double fabric by plain weaving warp threads 24, weft threads 25, and auxiliary threads 30. The fabric formwork 20 can be easily woven using, for example, a known loom.
[0019] In the flattened Heisei-shaped section 20a, the total length of the upper fabric 21 and the total length of the lower fabric 22 oriented in the Y direction are approximately equal, and in the thickened molding section 20b, the total length of the upper fabric 21 and the total length of the lower fabric 22 oriented in the Y direction are also approximately equal.
[0020] <2.2> Examples of yarn materials The materials for each of these threads 24, 25, and 30 can be appropriately selected from synthetic fibers such as polyester, nylon, aramid, fully aromatic polyester, polyethylene, polypropylene, and polyvinyl chloride; semi-synthetic fibers such as acetate; regenerated fibers such as rayon; inorganic fibers such as glass fiber; and natural fibers such as cotton and linen. Polyester is particularly practical from the standpoint of strength and cost-effectiveness. Each of these threads 24, 25, and 30 consists of a multifilament or monofilament formed by twisting and bundling single threads together.
[0021] <2.3> Bonding thread The auxiliary yarn 30 knitted into each fabric 21 and 22 is used as the bonding yarn. The connecting thread is a spacing adjustment member that adjusts the distance between the two fabrics 21 and 22, allowing each fabric 21 and 22 to function as a formwork surface. In this invention, multiple auxiliary threads 30 are used as two types of connecting threads (connecting short threads 31 and connecting long threads 32) of different lengths.
[0022] <2.3.1> Arrangement of connecting threads The connecting short threads 31 and connecting long threads 32 are in a strip shape and are routed between the two fabrics 21 and 22 in an X or V shape when the fabric formwork 20 is viewed from the side. In this example, we will describe a configuration in which multiple connecting short threads 31 located in the flattened Heiwa section 20a are arranged in an X shape, and multiple connecting long threads 32 located in the thickening molding section 20b are connected in a V shape. The arrangement of the connecting short thread 31 and connecting long thread 32 may be the opposite combination to that in this example, or the same combination.
[0023] <2.4> Flattened Heisei-shaped section The flattened Heisei-shaped section 20a is a mold for forming a thinner mat body compared to the thickened molding section 20b, while forming a plurality of protrusions 11 and recessed grooves 12 on at least its upper surface.
[0024] Referring to Figures 4A and 4B, the flattened Heiwa section 20a comprises an upper fabric 21, a lower fabric 22, and connecting short threads 31 that connect the two fabrics 21 and 22. In explaining the flattened section 20a, the area between the two fabrics 21 and 22 connected by the connecting short thread 31 is defined as the connecting section 31a, and the area between the two fabrics 21 and 22 that is not connected by the connecting short thread 31 is defined as the unconnected section 31b. In the flattened Heisei-shaped section 20a, the connecting portion 31a and the non-connecting portion 31b are formed alternately along the vertical direction Y.
[0025] <2.4.1> Connection part The connecting portion 31a in the flattened Heiwa section 20a works in cooperation with both fabrics 21 and 22 to create a series of hemispherical protrusions 11 when the solidifying material 40 is filled into the formwork space 23.
[0026] <2.4.2> Unconnected part In the flattened Heisei section 20a, the unconnected portion 31b is the part that is not connected by the connecting short thread 31, and the auxiliary thread 30 remains woven into both fabrics 21 and 22. The unconnected portion 31b works in cooperation with both fabrics 21 and 22 to form the groove portion 12 when the solidifying material 40 is filled into the formwork space 23. To form the recessed groove 12, it is preferable to make the vertical width P2 of the non-connected portion 31a oriented in the vertical direction Y narrower than the vertical width P1 of the connected portion 31 (Figure 3).
[0027] <2.5> Thickened molding section The thickened molding section 20b is a mold for forming a mat body that is thicker than the flattened Heiwa-shaped section 20a, while also forming a stepped protrusion 13 that rises in a stepped manner on its upper surface.
[0028] Referring to Figures 5A and 5B, the thickened molding section 20b comprises an upper fabric 21, a lower fabric 22, and a connecting long thread 32 that connects the two fabrics 21 and 22. In explaining the thickened molding section 20b, the area of the upper fabric 22 connected by the connecting short thread 32 will be defined as the connecting section 32a, and the areas of both fabrics 21 and 22 that are not connected by the connecting short thread 31 will be defined as the unconnected sections 32b and 32c.
[0029] <2.5.1> Connection part The connecting portion 32a in the thickened molding section 20b works in cooperation with both fabrics 21 and 22 to form the raised tip of the stepped protrusion 13 that rises on the surface side of the mat structure when the solidifying material 40 is filled into the formwork space 23.
[0030] <2.5.2> Unconnected part In the thickened molding section 20b, the unbonded sections 32b and 32c are areas not bonded by the bonding short yarn 31, and the auxiliary yarn 30 remains woven into both fabrics 21 and 22. The unbonded portion 31b in the upper fabric 21 functions to form the middle raised portion of the stepped protrusion 13 that rises on the surface side of the mat structure when the solidifying material 40 is filled into the formwork space 23. Furthermore, the unbonded portion 31c in the base material 22 functions to form the two raised portions when the solidifying material 40 is filled into the formwork space 23.
[0031] <2.6> Mold dimensions for forming the protruding section and the stepped protruding section (Figure 3) In order to make the stepped protrusion 13 of the thickened molding section 20b rise significantly higher than the protrusion 11 of the flattened Heisei-shaped section 20a, the vertical width of the upper molded material 21 that forms the stepped protrusion 13 of the thickened molding section 20b is set to be significantly larger than the vertical width of the upper molded material 21 that forms the protrusion 11 of the flattened Heisei-shaped section 20a.
[0032] <2.7> Bonding length of bonded short yarn and bonded long yarn (Figure 3) In order to make the raised height t2 of the stepped protrusion 13 formed in the thickened molding section 20b several times higher than the raised height t1 of the protrusion 11 formed in the flattened shaped section 20a, the connection length of the connecting long thread 32 connected in the thickened molding section 20b is set to be longer than the connection length of the connecting short thread 31 connected in the flattened shaped section 20a. The connection lengths of the connecting short thread 31 and the connecting long thread 32 are appropriately selected according to the raised heights t1 and t2 of the protrusion 11 and the stepped protrusion 13.
[0033] [Method for constructing rescue climbing structures] Next, we will explain the method for manufacturing the rescue climbing structure 10.
[0034] <1> Laying of fabric formwork At the installation site, a cloth formwork 20 is spread out and laid along the slope 51 of the pond 50. In this case, the upper fabric side 21 (front side) of the fabric formwork 20 is facing upwards, and the lower fabric side 22 (back side) is laid facing the slope 51. The lower edge of the fabric formwork 20 is left hanging in the water. If necessary, secure the upper end of the fabric formwork 20 to the top of the reservoir 50 or the like with anchor pins or the like.
[0035] <2> Filling with a binding agent A slurry-like solidifying material 40 is filled into the formwork space 23 through an injection port provided in a part of the fabric formwork 20 to construct a rescue climbing structure 10 that follows the undulations of the slope 51. By filling the fabric formwork 20 with a fixing material 40 on-site, the fabrication and installation of the rescue climbing structure 10 are carried out simultaneously.
[0036] Within the flattened Hei-shaped section 20a and the thickened molding section 20b that constitute the fabric formwork 20, a continuous mat structure is constructed. The mat body formed in the flattened Heisei section 20a and the thickened molding section 20b will be described in detail below.
[0037] <3> Forming of the mat structure in the flattened Heisei-shaped section (Figures 4A, 4B) The slurry-like solidifying agent 40 penetrates into every corner of the flattened Heiwa section 20a, causing both fabrics 21 and 22 to expand and increasing the thickness of the mat structure.
[0038] In the flattened Heiwa section 20a, the connecting short threads 31 arranged in an X shape form hemispherical protrusions 11 on the surface side of the connecting portion 31a and recessed grooves 12 on the surface side of the unconnected portion 31b in order to regulate the swelling of each fabric 21, 22 to a constant degree. In other words, both the protruding portion 11 and the recessed portion 12 are continuous in the lateral direction X of the rescue climbing structure 10 and are formed in a multi-stage arrangement along the vertical direction Y. The groove portion 12 has a thinner structural thickness compared to the protruding portion 11.
[0039] In the flattened Heisei-shaped section 20a, a thin mat structure of about 60 to 150 mm thickness is formed, and the upper and lower surfaces of the mat structure are formed with uneven surfaces that run horizontally.
[0040] <4> Forming of the mat structure in the thickened molding section (Figures 5A-5C) The slurry-like solidifying agent 40 penetrates into every corner of the thickened molding section 20b, causing both fabrics 21 and 22 to expand and increasing the thickness of the mat structure. The connecting long threads 32 arranged in a V-shape in the thickening molding section 20b form stepped protrusions 13 that are gradually raised on the surface side of the expanded connecting section 31b in order to regulate the swelling of each fabric 21, 22 to a consistent degree. The stepped protrusion 13 has a maximum elevation height of approximately 200 to 300 mm.
[0041] For example, if the consolidating material 40 is filled into the thickened molding section 20b without providing the connecting long threads 32, the mat structure will only be formed as a gently sloping curved surface because there is only one formwork surface for the upper fabric 21 located in the thickened molding section 20b, making it difficult to create a high elevation. If the height of the raised surface of the mat structure is low, the area available for victims to grip with their hands and feet (climbing surface) will be smaller.
[0042] In contrast, the present invention uses connecting long threads 32 to divide the mold surface of the upper fabric 21 located in the thickening molding section 20b into three sections along the height direction, thereby forming the stepped protrusion 13. Therefore, the lower half of the stepped protrusion 13 is formed as a gently curved surface with a greater curvature and a higher elevation height compared to the protrusion 11 of the flattened Hei-shaped section 20a. The upper half of the stepped protrusion 13 is formed as a gently curved surface with a greater curvature and a higher elevation compared to the protrusion 11 and the lower half of the stepped protrusion 13. Furthermore, an inwardly recessed intermediate constriction 14 is formed in the middle of the stepped protrusion 13 to which the connecting long threads 32 are linked.
[0043] <5> The uneven surface shape on the upper side of the mat body As described above, the protruding portion 11 and recessed groove portion 12 formed on the upper surface of the flattened Heiwa section 20a, and the stepped protruding portion 13 formed on the upper surface of the thickened section 20b, are formed along the entire length of the rescue climbing structure 10 in the transverse direction. Furthermore, the vertical base width of the stepped protrusion 13 formed on the upper side of the thickened section 20b is larger than the base width of the protrusion 11 formed on the upper side of the flattened section 20a.
[0044] [Safety effects of rescue climbing structures] This section explains the safety features provided by rescue climbing structures.
[0045] <1> Normal time The slope 51 of the reservoir 50 is covered with a rescue climbing structure 10, and large and small indentations are formed on the surface side of the rescue climbing structure 10. Therefore, walking on the surface of the rescue climbing structure 10 is less likely to cause slipping, and it is less likely to fall into the reservoir 50.
[0046] <2> When falling Even if one accidentally falls into the reservoir 50, they can escape by climbing up the rescue climbing structure 10 that covers the slope 51. In other words, on the surface side of the thickened molded section 20b that constitutes the rescue climbing structure 10, stepped protrusions 13 are formed in a step-like manner, rising along the lateral direction X of the rescue climbing structure 10. In particular, the increased height of the stepped protrusion 13 increases the area on which victims can grip with their hands and feet (climbing surface). Therefore, victims can safely climb up using the stepped protrusion 13 as a handhold.
[0047] Furthermore, the stepped projection 13 is formed continuously along the entire length of the rescue climbing structure 10 in the lateral direction X. Therefore, regardless of where they fell, victims can reach the stepped protrusion 13 simply by moving towards the nearest rescue climbing structure 10. Therefore, the goal is to minimize the physical exhaustion of disaster victims and make it easier for them to escape.
[0048] Furthermore, when a victim climbs up the rescue climbing structure 10, a step is formed between the protruding section 11 and the recessed groove 12 on the surface side of the flattened Hei section 20a, and if this step is also utilized, it becomes even easier for the victim to climb up.
[0049] [Differentiation] In the previous embodiment, a configuration was described in which multiple protrusions 11 in the flattened Hei-shaped section 20a were continuously formed in the lateral direction (cross-sectional direction of the slope) X of the fabric formwork 20. However, in the flattened Hei-shaped section 20a, multiple protrusions 11 may be provided intermittently and arranged in a staggered pattern. [Explanation of symbols]
