Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction material made of synthetic resin monofilament and made of a synthetic resin monofilament in a box shape having a mesh body knitted into a turtle shell shape made of a synthetic resin monofilament. Construction material made of synthetic resin monofilament that can be easily restored to its original box-shaped size on site by increasing the number of parts of the material, increasing the efficiency of the assembly work, and folding it down into a roll shape. The present invention relates to a material and a manufacturing method thereof.

A net made of a synthetic resin monofilament knitted in a turtle shell shape was originally manufactured as a sacrificial net by the applicant of this application with the cooperation of a major textile manufacturer. In order to knitting a wire made of synthetic resin monofilament into a turtle shell-shaped net, it is of course necessary to use a dedicated device, but in order to twist two wires into a turtle shell shape, each wire is pre-heated immediately before being knitted while pulling. It is necessary. The preheating temperature and the strength of the tension are slightly different each time depending on the thickness of the wire, the size of the turtle shell shape, and the weather conditions. If this is not appropriate, when it is knitted, it does not become a tortoise-shaped net having a predetermined strength and shape, and cannot be commercialized. In this way, a high level of manufacturing know-how is required, and the current situation is that no one other than the applicant of the present application manufactures.
A mesh made of synthetic resin monofilament wire in a turtle shell shape has advantages such as high water resistance, tensile strength stronger than iron wire, light weight, and resistance to ultraviolet rays. It is used. However, the difficulty is that it is expensive, but considering durability and high running costs, it is gradually understood that it is more advantageous than a net made of other materials, and has begun to spread. It is also used overseas as a huge cage net.
The applicant of the present application has begun to use this net as a rock fall prevention net for civil engineering on land other than the sea, taking advantage of the features such as durability, strength, light weight, and resistance to ultraviolet rays. Compared to iron wire mesh, as mentioned before, the high price was an obstacle to popularization at first, but iron wire mesh rusted in about 5 to 10 years depending on the location, and it was forced to replace Nevertheless, this net is known to have a durability of 20 to 30 years or more and is also light in weight, and is gradually spreading in consideration of running costs and workability in the mountains.
The applicant of the present application was thinking of a box-shaped civil engineering dredging using this net, with hints of a rock fall prevention net for civil engineering, but it was preceded by other companies. The leading company has obtained a patent (No. 4256448) for box-shaped civil engineering materials using this net.

By the way, according to the description of [0039] [0043] of the specification of the patent 4256448 "civil material for civil engineering, method for producing civil engineering material and kit for assembling civil engineering material" and FIG. 3 of the drawings, Civil engineering material A is composed of three parts, a first divided body D1, a second divided body D2, and a third divided body D3. Further, according to FIG. 1 of the drawings, the first divided body D1 has a rectangular flat plate shape, the second divided body D2 has an upward U-shaped shape, and the third divided body D3 has a downward inverted L shape. It has become.
Then, the first divided body D1, the second divided body D2, and the third divided body D3 are assembled in a box shape, and an inside portion is filled with a filling material such as crushed stone to serve as a lid of the third divided body D3. By connecting the peripheral edge of P6 with the adjacent edge, the civil engineering braid A packed with the filling material is obtained (see [0044] in the specification).

Japanese Patent No. 4256448

Since the construction material A for civil engineering of Patent No. 4256448 is composed of three parts, a first divided body D1, a second divided body D2 and a third divided body D3, parts having three different shapes are required, That's cumbersome.
Further, since the three parts are assembled in a box shape, the assembling work is complicated accordingly.
Furthermore, if the assembly work into the box shape is performed on site, it is expected that the work efficiency on site will be significantly reduced.
In order to avoid this, it is assembled in a box shape at the factory without connecting only the peripheral edge of the upper surface part P6 that becomes the lid, and when transporting it to the site, it will be folded and carried, It may take time and effort to restore the original size on site.
In addition, when laying a water-permeable mat on which the microbes that perform water purification functions adhere to the bottom part of the box-shaped civil engineering material, the water-permeable mat laid on the bottom part is shifted during the filling of the filling material. The work may not be smooth.

  Hereinafter, the present invention will be described more specifically based on embodiments for carrying out the invention described in the drawings.

  In the figure, a cage 1 for civil engineering made of a synthetic resin monofilament is formed in a box shape having a mesh body formed on a hexagonal turtle shell shape K on a wire a made of synthetic resin monofilament on six sides. The upper surface portion is constituted by a pair of facing lid surfaces 11 and 4, a box-shaped side surface 12 composed of four surfaces, and a box-shaped bottom surface 13 composed of a double bottom. Each surface of the lid surface 11, the side surface 12, and the bottom surface 13 is formed of a mesh surface obtained by knitting a wire rod a made of a synthetic resin monofilament into a turtle shell shape K.

  Synthetic resin monofilaments have excellent strength and durability. In particular, it has been proven that it is excellent in water resistance because it is used as a net for sacrifice. Since the civil engineering dredging material 1 is used in rivers, etc., with a filling material such as stones inside, the property of not rusting is valuable. For example, polyester having excellent durability and strength is used for the synthetic resin monofilament.

A synthetic resin monofilament wire a having a diameter of, for example, 2 mm to 5 mm is used. When the diameter is 2 mm, there are problems of insufficient strength and reduced durability. Also, if the diameter is 5 mm or more, it is difficult to knit into a hexagonal turtle shell shape K that can be used as the construction material 1 for civil engineering, and since it has excessive strength and durability, the economy is further reduced. is there. The tensile strength is preferably 10 kg / mm ² or more.

  A civil engineering fence 1 made of synthetic resin monofilament is composed of two parts, a net 2 without lid and a net 3 with lid. When these two parts are assembled into a box-shaped civil engineering frame material 1, the lidless mesh body 2 is a mesh body on the side where a part of the mesh body does not constitute the lid surface 11 of the frame material 1, and has a lid. The net body 3 is a net body on the side where a part of the net body constitutes the cover surface 11 of the coffin material 1.

  The lidless net 2 is made of a net obtained by knitting a wire material a made of a synthetic resin monofilament into a tortoiseshell shape K, and has a rectangular plane when viewed from the plane before processing. The lidless mesh body 2 is bent so that both ends of the mesh body in the axial direction t (see FIG. 4) of the twisted shaft b twisting two adjacent wires a constituting the turtle shell shape K are slightly overlapped. The bent piece 21 is formed. The bent pieces 21 are bent so that, for example, about 10 cm overlap each other. The bent piece 21 is formed by bending both ends of the mesh body in the axial direction t of the twisted shaft b so as to overlap each other, and both end sides of the lidless mesh body 2 in the axial direction t of the twisted shaft b are formed in a turtle shell shape. Since it is not a hexagon of K and is weak in strength, the end is bent and reinforced.

  On both sides in the axial direction t (see FIG. 4) of the twisted shaft b of the turtle shell shape K of the lidless net 2, a box-shaped civil engineering material facing toward the center from both ends where the bent pieces 21 are respectively formed. The bent piece 21 is bent upward, for example, at a right angle in the same direction as the bending direction of the bent piece 21 at a position separated by a length corresponding to a height of 1. The bending direction is such that when the portion bent upward at a right angle is assembled into the box-shaped civil engineering brace 1, the side surfaces 22 that face each other are formed. This is because the axial direction t of the K twist axis b is directed vertically.

  When the filling material is stuffed into the inside of the civil engineering timber 1, a strong bending force acts on the side surface 22 on the side face 22 due to the weight of the filling material, and the bending becomes easy. In order to prevent the side surface 22 from being easily bent, it is necessary to increase the bending rigidity that resists the bending moment acting around the up and down side. The direction of the twisted shaft of the turtle shell shape K plays the role of increasing the bending rigidity. When this is the vertical direction, the bending rigidity is increased, and the side surface 22 is prevented from being deformed by the weight of the filling material. is there.

  The unfolded portion between the opposing side surfaces 22 constitutes the bottom surface 23 on one side of the double bottom surface of the box-shaped civil engineering brazing material 1. The lidless net 2 has a U-shape when viewed from the side, and both sides bent at a right angle are side surfaces 22, and a central portion between both side surfaces 22 is a bottom surface 23.

  The lidded net 3 is made of a net obtained by knitting a wire material a made of synthetic resin monofilament into a tortoiseshell shape K, and has a rectangular plane when viewed from the plane before processing. The mesh body 3 with the lid is such that both sides of the mesh body in the axial direction t (see FIG. 4) of the twisted shaft b twisting two adjacent wires a constituting the turtle shell shape K are closer to the center side from both ends. It is bent at a right angle at a position separated by a length corresponding to the cover surface 11 of the box-shaped civil engineering material 1. When the two parts bent at right angles are assembled to the box-shaped civil engineering brazing material 1, they respectively constitute the lid surface 31 whose tip side partly overlaps vertically.

  For both sides of the tortoiseshell-shaped K twist axis b of the mesh body with lid 3 in the axial direction t (see FIG. 4), for the box-shaped civil engineering from the position where the lid surface 31 is bent at right angles toward the center side The lid 1 is bent upward at a position perpendicular to the same direction as the bending direction of the lid surface 31 at a position separated by a length corresponding to the height of the saddle member 1. The bending direction is such that when the portion bent upward at a right angle is assembled into the box-shaped civil engineering brace 1, the side surfaces 32 that face each other are formed, and the turtle shell shape formed on the side surfaces 32 is formed. This is because the axial direction t of the K twist axis b is directed vertically.

  When the filling material is packed inside the civil engineering pot 1, a strong bending force acts on the side surface 32 on the side surface 32 due to the weight of the filling material, and the bending becomes easy. In order to prevent the side surface 32 from bending easily from now on, it is necessary to increase the bending rigidity that resists the bending moment acting around the vertical side. The direction of the twisted shaft of the turtle shell shape K plays the role of increasing the bending rigidity. When this is the vertical direction, the bending rigidity is increased and the side surface 32 is prevented from being deformed by the weight of the filling material. is there.

  The unfolded portion between the facing side surfaces 32 constitutes a bottom surface 33 on one side of the double bottom surface of the box-shaped civil engineering brazing material 1. This lidded net body 3 has a rectangular frame shape when viewed from the side, the part where the tip side partly overlaps on the upper surface side becomes both lid surfaces 31, and both sides bent upward at right angles become side surfaces 32, A central portion between both side surfaces 32 becomes a bottom surface 33.

  The restoration wire 4 made of a synthetic resin monofilament serves to instantly restore the civil engineering cage 1 that has been rolled and folded into a small size when transported to its original box shape. As the restoration wire 4, for example, the same wire material a that forms the lidless net body 2 and the lidded net body 3 is bundled, for example, and twisted to form a single wire. The restoring wire 4 made of a synthetic resin monofilament has a sufficient restoring force when no heat is applied. Further, since the three bundles are bundled and twisted into one, the rigidity is increased compared to the wire material a of the nets 2 and 3, and the restoring force is also increased.

  The restoration wire 4 is attached along the edge or edge of the mesh 2 without lid or the mesh 3 with lid that is bent at a right angle, but if necessary, the mesh 2 without lid and the mesh 3 with lid are used. It may be attached along the edges or edges that are bent at both right angles.

  When the restoring wire 4 is attached to the lidless net 2 as shown in FIG. 1, it is attached to the following location, for example, as shown in FIG. The restoring wire 4 is formed by bending the peripheral edge of two sides, that is, the upper side edge 22a of both side faces 22, the left and right side edge edges 22b of the side faces 22 and the bottom face 23, by folding the folded piece 21 of the lidless net 2. It is attached along both width end edges 23a on the non-side. Of these, the restoring wire 4 attached to the left and right side edges 22b of the side surface 22 is oriented vertically. In addition, after being assembled into the civil engineering fence 1, the upper edge 22a of the side surface 22 becomes the upper edge 12a of the side surface 12, the side edge 22b of the side surface 22 becomes the side edge 12b of the side surface 12, and the side surface 22 The lower side edge 23a and the width end edge 23a of the bottom surface 23 on the unbent side become the lower side edge 12c of the side surface 12. The restoring wire 4 is inserted between the meshes of the turtle shell shape K. The restoring wire 4 is attached along the peripheral edges of the four sides between the rectangular shapes before being folded into the U-shape upward after folding the folded pieces 21 on both ends of the mesh body 2 without lid. It is done.

  Further, when the restoring wire 4 is attached to the net body 3 with a lid, it is attached to the following location, for example, as shown in FIG. The restoring wire 4 is formed by bending the peripheral edge of two sides obtained by bending the lid surface 31 of the mesh body 3 with lid at a right angle, that is, the upper edge 32a of the side surfaces 32, the left and right side edges 32b of the side surfaces 32, and the bottom surface 33. It is attached along both width end edges 33a on the non-side. Of these, the restoring wire 4 attached to the left and right side edges 32b of the side surface 32 is oriented vertically. In addition, after assembling to the civil engineering fence 1, the upper edge 32a of the side surface 32 becomes the upper edge 12a of the side surface 12, the side edge 32b of the side surface 32 becomes the side edge 12b of the side surface 12, and the side surface 32 The lower edge 32c and the width end edge 33a of the bottom surface 33 on the unbent side become the lower edge 12c of the side surface 12. The restoring wire 4 is inserted between the meshes of the turtle shell shape K. The restoring wire 4 is attached along the peripheral edges of the four sides after the lid surfaces 31 on both sides of the mesh body 3 with lid are bent at right angles or on the planned folding line before the lid surface 31 is folded.

  A civil engineering fence 1 made of a synthetic resin monofilament has opposite side surfaces 22 bent at a right angle upward with respect to a bottom surface 23 of a lidless mesh body 2 constituting the same and a bottom surface 33 of a lidded mesh body 3 configured similarly. The bottom surface 23 of the lidless net body 2 and the bottom surface 33 of the lidded net body 3 are stacked one above the other so that the opposite side surfaces 32 bent at a right angle with respect to each other have a right-angle positional relationship when viewed from above. It is matched.

  The bottom surface 23 of the mesh body 2 with no lid and the bottom surface 33 of the mesh body 3 with the lid are overlapped with each other, and the bottom surface of the civil engineering cage 1 is doubled. For this reason, this double bottom surface is rolled into a roll shape during transportation and folded down into a small size by folding it into the original box shape in cooperation with the restoration wire 4 There is work to help you.

  When the restoration wire 4 is attached to the mesh body 2 with no lid when the top and bottom are overlapped, the bottom surface 23 of the mesh body 2 with no lid is on the lower side, and the bottom surface 33 of the mesh body 3 with the lid is on the upper side. It is superimposed. On the contrary, when the restoring wire 4 is attached to the net body 3 with the lid, it is overlapped with the bottom surface 33 of the net body 3 with the lid facing down and the bottom surface 23 of the net body 2 without the lid facing up. Yes.

  Both side edges 22b of the side surface 22 of the lidless mesh body 2 that are stacked vertically and touch each other at right angles, and both side edge edges 32b of the side surface 32 of the mesh body 3 with a lid, as shown in FIG. 7, are synthetic resin monofilaments. They are connected by a connecting wire 14 made of a metal. The connecting wire 14 connects the side edges 32b of the side surface 32 that are in contact with the side edges 22b of the side surface 22 at right angles while being spirally wound. That is, the connecting wire 14 includes a side edge 22b of the side surface 22 that is parallel to the axial direction t (see FIG. 4) of the twisted shaft b of the turtle shell shape K, and a turtle shell shape K of the side edge 32b of the side surface 32. The ends parallel to the axial direction t of the twisted shaft b are inserted alternately while being spirally wound between the meshes of the turtle shell K.

  Further, the width edge 23a of the bottom surface 23 of the mesh body 2 without lid and the lower edge 32c of the side surface 32 of the mesh body 3 with lid are connected by a connecting wire 14 made of synthetic resin monofilament. The connecting wire 14 connects the width end edge 23a of the bottom surface 23 and the lower edge 32c of the side surface 32 in contact with the top and bottom at a right angle while being spirally wound. That is, the connecting wire 14 has an end side parallel to the axial direction t of the twisted shaft b of the turtle shell shape K of the width end edge 23a of the bottom surface 23 and a lower side edge 32c of the side surface 32 alternately. It is inserted while spirally winding between the meshes.

  A connecting wire 14 for connecting one side edge 22b of the side surface 22 of the lidless net body 2 and one side edge 32b of the side surface 32 of the lidded net body 3, and a bottom surface 23 of the lidless net body 2 The connecting wire 14 that connects the end edge 23a and the lower edge 32c of the side surface 32 of the mesh body 3 with lid halfway is made of the same wire a and is continuously connected. Similarly, the connecting wire 14 that connects the other side edge 22b and the side edge 32b and the other connecting wire 14 that connects the width edge 23a and the lower edge 32c halfway are the same 1 It consists of a wire rod a. The central portions of the width edge 23a and the lower edge 32c are partially overlapped and connected by the two connecting wires 14.

  The water-permeable mat 5 is formed by irregularly arranging chemically synthesized fibers excellent in water resistance, weather resistance, and corrosion resistance to form a nonwoven fiber layer, and has strength and elasticity. When purifying a river by attaching microorganisms that perform water purification functions to the bottom surface portion, it is sandwiched between the bottom surface 23 of the lidless net 2 and the bottom surface 33 of the lidded net 3. Used. The water-permeable mat 5 may be made of natural fibers other than chemically synthesized fibers. This water-permeable mat 5 is also used for preventing the pebbles passing through the mesh of the turtle shell K on the bottom surfaces 23 and 33 from flowing out.

  Since the water-permeable mat 5 is sandwiched between the bottom surface 23 of the lidless net body 2 and the bottom surface 33 of the lidded net body 3, a filling material is placed in the interior of the civil engineering cage 1. Even when stuffed, there is no fear that it will shift due to the weight of the filling material. The water-permeable mat 5 has a rectangular shape that is substantially the same size as the planar size of the bottom surfaces 23 and 33. Further, since the water-permeable mat 5 has elasticity and resilience, the civil engineering cage material 1 that has been rolled down and folded to be small during transportation becomes the original box shape in cooperation with the restoration wire 4. There is a work that helps to instantly restore the shape.

  As shown in FIG. 8, a suspension ring 6 is attached to the upper side of a pair of side surfaces 12 facing a civil engineering cage 1 made of synthetic resin monofilament. The suspension ring 6 is a portion that is hooked by a crane hook when the civil engineering bridging material 1 packed with the filling material is lifted by a crane. The suspension ring 6 is formed at both ends of the cord 61. The cord 61 in which the suspension ring 6 is formed is integrally attached along the outer periphery of the side surface 12 facing the bottom surface 13 of the civil engineering fence 1. The suspension rings 6 at both ends are attached so as to protrude above the side surface 12.

  When the civil engineering fence 1 is small, two suspension rings 6 are attached to the side surface 12 on one side, for a total of four. When the civil engineering fence 1 becomes large in size, the number of the suspension rings 6 increases in accordance with the size, and may be attached to all four side surfaces 12.

Next, the manufacturing method of the cage | basket material 1 for civil engineering made from a synthetic resin monofilament is demonstrated below.
The civil engineering fence 1 is composed of two parts, a net without lid 2 and a net with lid 3. The net without lid 2 and the net with lid 3 are produced as follows.

The lidless net 2 is manufactured as follows.
A flat mesh surface obtained by knitting a wire rod a made of a synthetic resin monofilament into a hexagonal turtle shell shape K is cut into a rectangular shape having a predetermined size. At this time, it is cut in a direction orthogonal to the axial direction t (see FIGS. 4 and 5) of the twisted shaft b of the turtle shell K. Both width ends parallel to the axial direction t of the twisted shaft b are manufactured in advance so as to have the width size when knitted into a turtle shell shape K.

  The both ends of the flat mesh body 2 without the lid 2 in the axial direction t of the twisted shaft b of the turtle shell shape K are bent so that, for example, about 10 cm overlap each other. Bending pieces 21 are formed at both end portions of the lidless net 2. As described above, this is to increase the strength of both end portions in the axial direction t of the twisted shaft b of the turtle shell shape K of the lidless net 2.

  When the restoration wire 4 is attached to the net 2 without the lid, the peripheral edges of the two sides obtained by folding and overlapping the folded pieces 21 of the net 2 without the lid and the other two sides that were not folded Attached to the peripheral edge. The restoring wire 4 is attached by being inserted between the meshes of the turtle shell K (see FIG. 6C). This operation is omitted when the restoration wire 4 is not attached to the net 2 without the lid.

  At this time, the lidless net 2 is not bent upwards into a U-shape and is flat, so that the attaching work of the restoring wire 4 becomes easier. After the lidless net 2 was folded upwards into a U-shape, the restoration wire 4 was attached at the location where the peripheral edges of the two sides folded and overlapped were the upper edges 22a of the side faces 22 and were not folded. The peripheral edges of the other two sides are left and right side edges 22b of the side faces 22 and both width edges 23a of the bottom face 23 that are not bent.

  The side faces 22 are formed by bending upward at right angles from the both ends where the bent pieces 21 are formed toward the center at respective length positions corresponding to the height of the civil engineering brace 1. As a result, the lidless net 2 is formed in an upwardly U-shaped shape with side surfaces 22 formed on both sides and a central portion serving as a bottom surface 23.

The net body 3 with a lid is manufactured as follows.
A flat mesh surface obtained by knitting a wire rod a made of a synthetic resin monofilament into a hexagonal turtle shell shape K is cut into a rectangular shape having a predetermined size. At this time, it is cut in a direction orthogonal to the axial direction t (see FIGS. 4 and 5) of the twisted shaft b of the turtle shell K. Both width ends parallel to the axial direction t of the twisted shaft b are manufactured in advance so as to have the width size when knitted into a turtle shell shape K.

Corresponding to the cover surface 11 of the box-shaped civil engineering brace 1 with both sides of the mesh in the axial direction t of the twisted shaft b of the turtle shell shape K of the flat mesh body 3 with lid facing from the both ends toward the center side. At a position separated by the length to be
Fold each side up at a right angle. The bent portion is the lid surface 31. After this lid surface 31 is assembled in a box shape, it becomes the lid surface 11 of the civil engineering fence 1.

  When the restoration wire 4 is attached to the net body 3 with the lid, the restoration wire 4 is attached along the planned folding line before the folding, or after the folding, the restoration wire 4 is bent. And the restoration wire 4 is attached to the peripheral edges of the other two sides that could not be bent. The restoring wire 4 is attached by being inserted between the meshes of the turtle shell K (see FIG. 6C). This operation is omitted when the restoration wire 4 is not attached to the net body 3 with the lid.

  When attaching before bending, since it is planar, the attachment work of the restoring wire 4 becomes easier. After the lidded net body 3 is bent into a rectangular frame shape, the restoration wire 4 is attached at the place where the two bent sides are the upper side edges 32a of the side faces 32, and the other 2 parts that are not bent. The peripheral edges of the sides are left and right side edges 32b of both side faces 32 and both width edges 33a of the bottom face 33 which are not bent.

  From the lower end where the lid surface 31 is formed by being bent upward at a right angle from the lower end toward the center, the side surfaces 32 are respectively formed by bending further upward at a length corresponding to the height of the civil engineering brace 1. . Prior to this, the lid surface 31 is bent upward at a right angle from the upward state to the horizontal state, and the top surfaces of the lid surfaces 31 partially overlap each other vertically. Thus, the lidded net body 3 is formed in a rectangular frame shape in which a pair of lid surfaces 31 are formed on the upper surface, side surfaces 32 are formed on both sides, and a central portion on the lower surface is the bottom surface 33.

Subsequently, the civil engineering fence 1 is produced by combining the lidless net 2 and the lidded net 3 as follows.
The pair of side faces 22 of the mesh body 2 without lid and the pair of side faces 32 of the mesh body 3 with lid are attached so as to be orthogonal to each other. That is, the side edge 22b of the side surface 22 and the side edge 32b of the side surface 32 are attached so as to be adjacent to each other at a right-angled corner.

  In this case, when the restoring wire 4 is attached to the peripheral side of the lidless net body 2, the bottom surface 23 of the lidless net body 2 is on the lower side, and the bottom surface 33 of the lidded net body 3 is overlaid from the upper side. (See FIG. 1). When the restoring wire 4 is attached to the peripheral side of the net body 3 with the lid, conversely, the bottom surface 33 of the net body 3 with the lid is on the lower side, and the bottom surface 23 of the net body 2 without the lid is overlaid from the upper side. (See FIG. 2). In any case, it is preferable that the net body 2 or the net body 3 on the side where the restoring wire 4 is attached be on the lower side. When the restoration wire 4 is attached to both the nets 2 and 3, either one may be on the lower side.

  When the water-permeable mat 5 is attached between the bottom surfaces 23 and 33, the water-permeable mat 5 is laid on the bottom surface side, and then the upper and bottom surfaces are covered from above. 23 and 33 are sandwiched (see FIGS. 1 to 3). The water-permeable mat 5 is prevented from slipping by being sandwiched between the upper and lower bottom surfaces 23 and 33.

  Then, the side edge 22b of the side surface 22 and the side edge 32b of the side surface 32 which adjoin each other at a right-angled corner are connected using the connecting wire 14 (see FIG. 7). The connecting wire 14 is continuously connected upward from the lower ends of the side edges 22b and 32b after being connected while spirally winding a part of the lower edge 32c of the side surface 32 and the width end edge 23a of the bottom surface 23. Connect while winding in a spiral. The connecting force of the side edges 22b and 32b is such that the lower edge 32c of the side surface 32 and the width edge 23a of the bottom surface 23 are continuously connected rather than connecting only the side edges 22b and 32b. Become stronger.

  By the above method, a civil engineering fence made of a box-shaped synthetic resin monofilament having an upper surface portion composed of a pair of lid surfaces 11, a side peripheral surface portion having four side surfaces 12, and a bottom surface 23, 33 having a double bottom surface portion. Material 1 is produced.

  When transporting the box-shaped synthetic resin monofilament material 1 for civil engineering to the site, the top and bottom are overlapped so that the lid surface 11 and the double bottom surfaces 23 and 33 overlap (FIG. 9A). reference). At this time, the four side surfaces 12 are temporarily bent in an arc shape at an intermediate portion in the height direction. This is wound in a roll shape in the longitudinal direction of the civil engineering fence 1 (see FIG. 9 (B)), and the outer peripheral side is temporarily wound with a string c so as not to return to the original box shape ( (Refer to FIG. 9 (C)).

  When used in the field, when the fixed string c is removed, the restoring wire 4 returns to the original box-shaped civil engineering brace 1 instantaneously. That is, since the restoration wire 4 is attached to the adjacent corners of the four side surfaces 12 in the vertical direction, the four side surfaces 12 temporarily bent in an arc shape function as the restoration wire material 4. To return to the vertical line. Further, a lid wound in a roll shape by the cooperation of the restoring wire 4 attached to at least one of the upper edge 12a or the lower edge 12c of the side surface 12 and the bottom surfaces 23 and 33 having a double bottom. The surface 11 and the bottom surfaces 23 and 33 return to a flat shape. Further, when the water-permeable mat 5 is sandwiched between the bottom surfaces 23 and 33, the function of the water-permeable mat 5 is also added, and it becomes easier to return to a flat shape.

  Thereafter, the pair of lid surfaces 11 are opened upward, the inside filling material such as chestnut is filled therein, the pair of lid surfaces 11 are closed, and the peripheral and part of the pair of lid surfaces 11 are overlapped. It connects with 14 and it fixes so that a pair of cover surface 11 may not open. The suspension ring 6 attached to the civil engineering fence 1 is hooked with a crane hook, and the synthetic resin monofilament civil engineering casing 1 filled with the filling material is moved to a predetermined installation location and lowered.

  The present invention is not limited to the embodiment for carrying out the invention, and it goes without saying that various modifications can be made without departing from the spirit of the invention.
