Description
本発明は、土木工事等で行われる嚢を製造する装置に関し、詳しくは、水防、砂防工事における土嚢製造や、東日本大震災後の放射能汚染土砂等を収納するために土嚢袋に土砂や廃棄物を梱包する際に現場で用いる土嚢を製造する装置に関する。 TECHNICAL FIELD The present invention relates to an apparatus for producing a sac that is used in civil engineering work, and more particularly, for producing sand sack in flood control and sabo works, and for storing sand and waste in a sand bag to store radioactively contaminated soil after the Great East Japan Earthquake. The present invention relates to an apparatus for manufacturing a sandbag used in the field when packing.
従来、水害等の減災段階若しくは発生時において、土嚢によって河川等からの水の流出を防ぐ処置が施される場合や、仮設土留め構造物、仮護岸工及び仮締切工、その他、東日本大震災以後の汚染土砂等の長期備蓄において、大規模な工事に多くの大型土嚢が用いられている。
土嚢とは、密閉性のある丈夫な袋に、土、砂、廃棄物などを入れたものである。土嚢を複数積み上げ、壁状にすることによって、水の流出をブロックしたり、堤防の補強などを行うものである。大きさは、１０ｋｇ程度のものから２ｔ程度のものまで様々なものがある。
２ｔ程度のものを使用する場合、輸送も大掛かりになることから、現場で製造することが多い。現場での作業において、袋の支持を人が行うと、安全確保のリスクが伴うだけでなく、効率も悪い。特に、土嚢を製造する現場は、平坦に整地された状態でない場合も多いことから、地面に多少の隆起、陥没があっても、問題なく土嚢製造ができる技術が求められており、更に緊急性が高い場合では、一度に複数の土嚢を効率よく製造する必要があることから、安全に大容量の土嚢を効率よく複数製造できる技術が求められていた。
Conventionally, when sandblasts have been used to prevent outflow of water from rivers, etc., during temporary disaster mitigation or occurrence, temporary earth retaining structures, temporary bank protection works and temporary cut-off works, etc., after the Great East Japan Earthquake Many large sandbags are used for large-scale construction in the long-term storage of contaminated earth and sand.
A sandbag is a durable and tightly sealed bag filled with dirt, sand, waste, and the like. By stacking multiple sandbags into a wall shape, water outflow can be blocked and embankments can be reinforced. There are various sizes ranging from about 10 kg to about 2 t.
When using a thing of about 2t, since transportation also becomes large, it is often manufactured on-site. In the field work, if a person supports the bag, not only will there be a risk of ensuring safety, but it will also be inefficient. In particular, the sandbag manufacturing site is often not flatly leveled, so even if there are some bumps and depressions on the ground, there is a need for technology that can produce sandbags without problems, and it is more urgent. However, since it is necessary to efficiently produce a plurality of sandbags at a time, a technology capable of safely and efficiently producing a plurality of large-capacity sandbags has been demanded.
このような問題に対して、従来からも様々な技術が提案されている。例えば、土嚢の袋詰めを能率よく行う技術（特許文献１参照）が提案され、公知技術となっている。より詳しくは、上端が開口し内部に土のう袋Ｗを挿入する筒状の仕切枠１を複数個一体的に連設して単一の支持枠３を構成する。そして各仕切枠１の上端には仕切枠１内に挿入した上記土のう袋Ｗの開口部を折返して係止し開口状態で保持する開口枠２を設ける。さらに袋詰作業時に上記開口枠２間の隣接間隙を覆うように支持枠３上に載置される平板状の土受けカバー１０を設け、該土受けカバー１０には支持枠３上に載置した状態で各開口枠２と対応する投入孔１１と、該投入孔１１の外周に下向きに突設され開口枠２内に挿入されて土のう袋Ｗを開口状態で保持するガイド１２とをそれぞれ設けている構造である。
複数の土嚢を一度に製造する技術である。しかしながら、製造した土嚢を、重機などで引き上げ、土嚢を移動しなければならず、効率的ではない。また、支持枠で構成された矩形部は、地面が平坦でないと、支持枠自体がゆがんでしまい、土嚢製造に支障がでる構造である。そのため、前記問題の解決には至っていない。
Various techniques have been proposed for such problems. For example, a technique for efficiently packing sandbags (see Patent Document 1) has been proposed and has become a publicly known technique. More specifically, a single support frame 3 is formed by integrally connecting a plurality of cylindrical partition frames 1 that are open at the upper end and into which a sandbag W is inserted. An opening frame 2 is provided at the upper end of each partition frame 1 to fold and lock the opening of the sandbag W inserted in the partition frame 1 and hold it in an open state. Further, a plate-like earth receiving cover 10 placed on the support frame 3 is provided so as to cover the adjacent gap between the opening frames 2 during the bagging operation, and the earth receiving cover 10 is placed on the support frame 3. In this state, there are provided the insertion holes 11 corresponding to the respective opening frames 2 and the guides 12 projecting downward on the outer periphery of the insertion holes 11 and inserted into the opening frame 2 to hold the sandbags W in the open state. It is a structure.
This is a technique for manufacturing multiple sandbags at once. However, the manufactured sandbag must be lifted with a heavy machine or the like to move the sandbag, which is not efficient. In addition, the rectangular portion formed of the support frame has a structure in which, if the ground is not flat, the support frame itself is distorted and hinders sandbag production. For this reason, the problem has not been solved.
また、三角柱形状、四角柱形状、半円柱形状、円柱形状、立方体状または直方体状などの特定形状に整形された土嚢を、簡単に製造する技術（特許文献２参照）が提案され、公知技術となっている。より詳しくは、木製、鉄製、プラスチック製またはＦＲＰ製のいずれかを材料として、三角柱形状、四角柱形状、半円柱形状、円柱形状、立方体状または直方体状などの形状に型枠を形成し、その側面の一部が開閉自在なるように形成するとともに当該型枠の側面外側に型枠締付け用バンドを装着するようにした土嚢用特定形状型枠と、麻布、ラッセルネットまたはＦＲＰ製の土嚢用袋体と、土壌と、バイブレーターとを用意し、前記土嚢用袋体の中に土壌を詰めて土嚢となし、この土嚢を前記土嚢用特定形状型枠に入れて型枠締付け用バンドで締付け固定したうえ、バイブレーターにより振動することにより土嚢用特定形状型枠内の土嚢を当該型枠に添った特定形状に整形するようにした構造である。
土嚢を製造後、土嚢製造用枠を分離し、土嚢から外す構造であるので、製造した土嚢を移動させる必要が無いので、効率的である。しかしながら、製造枠のベルトを一端はずす必要があり、その点で効率的でない。また、構造上、複数の土嚢を一度に作ることが困難である。そのため、前記問題の解決には至っていない。
In addition, a technique (see Patent Document 2) for easily producing a sandbag shaped into a specific shape such as a triangular prism shape, a quadrangular prism shape, a semi-cylindrical shape, a cylindrical shape, a cubic shape or a rectangular parallelepiped shape has been proposed. It has become. More specifically, a formwork is formed in a shape such as a triangular prism shape, a quadrangular prism shape, a semi-cylindrical shape, a cylindrical shape, a cubic shape, or a rectangular parallelepiped shape using any one of wood, iron, plastic, or FRP as a material. A specific shape mold for sandbags formed so that a part of the side surface can be opened and closed, and a band for fastening the formwork is attached to the outside of the side surface of the mold, and a sandbag bag made of linen, russell net or FRP A body, soil, and a vibrator are prepared, and the sandbag is filled with soil to form a sandbag. The sandbag is placed in the specific shape mold for the sandbag and fixed with a band for fastening the mold. In addition, the structure is such that the sandbag in the specific shape mold for sandbag is shaped into a specific shape along with the mold by vibrating with a vibrator.
After the sandbag is manufactured, the sandbag manufacturing frame is separated and removed from the sandbag, which eliminates the need to move the manufactured sandbag, which is efficient. However, it is necessary to remove one end of the belt of the manufacturing frame, which is not efficient in that respect. In addition, due to the structure, it is difficult to make a plurality of sandbags at a time. For this reason, the problem has not been solved.
また、土嚢を容易に安価に迅速に作成する方法（特許文献３参照）が提案され、公知技術となっている。より詳しくは、二本の支持脚（１）がＸ型に組み合わさり、土嚢袋を支持する支持体となり、その上辺部（８）に土嚢袋（２６）の口を広げて引っ掛けた上から、重しとなる被せ具（９）を掛ける構造である。比較的単純な構造の土嚢製造装置であり、軽量であり、効率的に土嚢を製造できるが、複数の土嚢を同時に製造できないことから、前記問題の解決には至っていない。 In addition, a method for easily and quickly creating a sandbag (see Patent Document 3) has been proposed and is a known technique. More specifically, the two support legs (1) are combined in an X shape to become a support body that supports the sandbag, and after the mouth of the sandbag (26) is spread and hooked on the upper side (8), This is a structure in which a cover (9) serving as a weight is hung. Although it is a sandbag manufacturing apparatus having a relatively simple structure and is light in weight and can efficiently manufacture sandbags, a plurality of sandbags cannot be manufactured at the same time.
本発明者はそれらの問題を解決しようと、複数の円筒形状からなる構造に着目し、「土嚢製造装置」の提案に至るものである。 In order to solve these problems, the inventor pays attention to a structure composed of a plurality of cylindrical shapes and leads to a proposal of a “sandbag manufacturing apparatus”.
本発明は、複数の大容量の土嚢を平坦に整地されていない現場で効率よく製造できないという問題点に鑑み、複数の円筒部からなる構造によって、この問題を解決する手段を提供するものである。 In view of the problem that a plurality of large-capacity sandbags cannot be efficiently manufactured on a site that is not leveled flat, the present invention provides means for solving this problem by a structure composed of a plurality of cylindrical portions. .

土嚢製造装置１は、主に、円筒部１００と連結部２００とから構成されている。概要としては、土嚢製造装置１を、現場の地面に設置し、円筒部１００内に土嚢袋４００を入れ、土嚢袋４００に土砂Ｄを入れ、土嚢が完成した後、土嚢製造装置１をワイヤＹによって、上方に引き上げることで、地面に完成した土嚢が残る形式の土嚢製造装置である。
図１は、土嚢が完成し、土嚢製造装置１を３本のワイヤＹを介して、クレーン等で上方に引き上げる工程の斜視図である。
The sandbag manufacturing apparatus 1 mainly includes a cylindrical portion 100 and a connecting portion 200. As an outline, the sandbag manufacturing apparatus 1 is installed on the ground at the site, the sandbag bag 400 is put in the cylindrical portion 100, the sandbag D is put in the sandbag bag 400, and the sandbag is completed. Thus, the sandbag manufacturing apparatus of the type in which a completed sandbag remains on the ground by being pulled upward.
FIG. 1 is a perspective view of a process in which a sandbag is completed and the sandbag manufacturing apparatus 1 is pulled up with a crane or the like through three wires Y.
円筒部１００は、上下に開口部が向くように配置された円筒状の形状である。内部に土嚢袋４００を入れ、土嚢を製造する際の、土嚢袋４００の支えの役割を果たす。１ｔ（トン）、２ｔ（トン）土嚢を製造する場合に、土嚢から支えへの圧力は、大変大きいことから、円筒部１００は金属が望ましい。また、圧力に対して、周方向に均等の強度を持つことが望ましいことから、シームレス鋼管を使用すると好適である。
また、土嚢完成後、土嚢袋４００に対して円筒部１００を上部に引き上げる作業を行うので、円筒部１００の内壁と土嚢袋４００との摩擦力を軽減するために、円筒部１００の内壁は滑らかであると好適である。
円筒部１００の上部には、土嚢袋４００の開口部または開口部に付加された縛り紐４１０を固定する紐用リング１１０が適宜配置されている。紐用リング１１０を用いることで、土嚢袋４００の開口が不用意に閉じたり、開口径が小さくなってしまうことを防ぐことができる。円筒部１００同士は、円筒部１００の上下方向に中間付近で、連結部２００を介して固定されている。また、円筒部１００同士は、円筒部１００の底部で、補強部３００を介して固定されている。
また、２ｔ土嚢を製造する場合は、円筒部１００の直径が約１ｍ、高さが１．１ｍ程度が適当である。 円筒部１００は、３つ配置されている。円筒部１００の数は、複数であれば、２個でも４個でも６個でも良いが、土嚢製造装置１の強度維持の点から、３つ程度が適当である。
The cylindrical portion 100 has a cylindrical shape that is arranged so that the opening is directed vertically. The sandbag bag 400 is put inside and plays a role of supporting the sandbag bag 400 when the sandbag is manufactured. When manufacturing 1t (ton) and 2t (ton) sandbags, the pressure from the sandbag to the support is very large, so the cylindrical portion 100 is preferably made of metal. In addition, since it is desirable to have a uniform strength in the circumferential direction against pressure, it is preferable to use a seamless steel pipe.
In addition, after the sandbag is completed, an operation of pulling the cylindrical portion 100 upward is performed on the sandbag bag 400. Therefore, in order to reduce the frictional force between the inner wall of the cylindrical portion 100 and the sandbag bag 400, the inner wall of the cylindrical portion 100 is smooth. Is preferable.
On the upper part of the cylindrical part 100, an opening part of the sandbag bag 400 or a string ring 110 for fixing the binding string 410 added to the opening part is appropriately arranged. By using the string ring 110, it is possible to prevent the opening of the sandbag 400 from being closed carelessly or the opening diameter from being reduced. The cylindrical parts 100 are fixed to each other in the vertical direction of the cylindrical part 100 via a connecting part 200 in the vicinity of the middle. The cylindrical portions 100 are fixed to each other at the bottom of the cylindrical portion 100 via the reinforcing portion 300.
When manufacturing a 2t sandbag, it is appropriate that the diameter of the cylindrical portion 100 is about 1 m and the height is about 1.1 m. Three cylindrical portions 100 are arranged. The number of the cylindrical portions 100 may be two, four, or six as long as it is plural, but about three is appropriate from the viewpoint of maintaining the strength of the sandbag manufacturing apparatus 1.
連結部２００は、隣接する円筒部１００同士を連結する部分である。Ｈ鋼材で形成され、上と下に広面をもつように配置されている。Ｈ鋼材をこのように用いることで、連結部２００としての強度が増し、土嚢袋４００に土砂を流し込む際、土嚢袋４００を安定して支持できるし、土嚢製造装置１の上方への引き上げる際のゆがみも小さくなるので、土嚢製造装置１をスムーズに引き上げることができる。
３つの円筒部１００から構成されているので、連結部２００の数も３つとなる（図２（ａ））。連結部２００の上部には、牽引部２１０が配置されている。牽引部２１０は、リング状であり、土嚢製造装置１を完成した土嚢から分離する際に、使用する。それぞれの牽引部２１０にワイヤを固定し、土嚢製造装置１を上方に引き上げる。引き上げる力は、３か所に分散するので、安定して土嚢製造装置１を引き上げることができる。
The connecting part 200 is a part that connects the adjacent cylindrical parts 100 together. It is made of H steel and is arranged with a wide surface at the top and bottom. By using the H steel material in this way, the strength as the connecting portion 200 is increased, and when pouring the sand and sand into the sandbag bag 400, the sandbag bag 400 can be stably supported and when the sandbag manufacturing apparatus 1 is pulled up. Since distortion also becomes small, the sandbag manufacturing apparatus 1 can be pulled up smoothly.
Since it is comprised from the three cylindrical parts 100, the number of the connection parts 200 will also be three (FIG. 2 (a)). On the upper part of the connecting part 200, a pulling part 210 is arranged. The towing unit 210 has a ring shape and is used when the sandbag manufacturing apparatus 1 is separated from the completed sandbag. A wire is fixed to each pulling part 210, and the sandbag manufacturing apparatus 1 is pulled up. Since the pulling force is distributed in three places, the sandbag manufacturing apparatus 1 can be lifted stably.
図３に沿って、土嚢の製造過程を示す。まず、土嚢製造装置１を地面Ｅに設置する。土嚢製造装置１の円筒部１００は、上下に開口部があるため、円筒部１００の上部の開口部からは、円筒部１００に下部の開口部に接した地面Ｅが見える。土嚢製造装置１の底面は、円筒部１００の円周部分で接地しているのみであるので、地面Ｅが若干凸凹していても、問題なく設置できる。もし、円筒部１００の下部が閉じた構造であると、地面Ｅが若干凸凹しているだけで、円筒部１００の底部と地面Ｅとの間に無用な隙間が生じ、その上に土嚢袋４００を配置し、土嚢を作成しようとすると、円筒部１００の底部は、土嚢袋４００内の土砂Ｄの重量によって、ゆがみが生じ、土嚢製造装置１自体の劣化を早めることになる。 A sandbag manufacturing process is shown along FIG. First, the sandbag manufacturing apparatus 1 is installed on the ground E. Since the cylindrical part 100 of the sandbag manufacturing apparatus 1 has upper and lower openings, the upper part of the cylindrical part 100 can see the ground E in contact with the cylindrical part 100 and the lower opening. Since the bottom surface of the sandbag manufacturing apparatus 1 is only grounded at the circumferential portion of the cylindrical portion 100, it can be installed without any problems even if the ground E is slightly uneven. If the lower part of the cylindrical part 100 is closed, the ground E is only slightly uneven, and an unnecessary gap is generated between the bottom of the cylindrical part 100 and the ground E, and the sandbag 400 When the sandbag is to be created, the bottom of the cylindrical portion 100 is distorted due to the weight of the sand and sand D in the sandbag bag 400, and the deterioration of the sandbag manufacturing apparatus 1 itself is accelerated.
また、円筒部１００は、土嚢袋４００を包み込む構造ではなく、土嚢袋４００の側面を支えるであるので、土嚢袋４００を包み込む構造に比べて、土嚢製造装置１自体を軽量化することができる。
円筒部１００内に、土嚢袋４００を入れ、土嚢袋４００の開口部又は開口部に付した縛り紐４１０を紐用リング１１０に固定する（図３（ａ））。土嚢袋４００内に土砂Ｄを流入させる際に、開口部が閉じてしまったり、開口部が小さくなってしまうことを防ぐためである。３つの円筒部１００に対して、同様に土嚢袋４００を配置する。
Moreover, since the cylindrical part 100 is not the structure which wraps the sandbag bag 400, but supports the side surface of the sandbag bag 400, compared with the structure which wraps the sandbag bag 400, the sandbag manufacturing apparatus 1 itself can be reduced in weight.
The sandbag bag 400 is put into the cylindrical portion 100, and the tied portion 410 attached to the opening portion or the opening portion of the sandbag bag 400 is fixed to the string ring 110 (FIG. 3A). This is to prevent the opening from being closed or the opening from becoming smaller when the sand and sand D is allowed to flow into the sandbag bag 400. The sandbags 400 are similarly arranged on the three cylindrical portions 100.
次に、重機等を用いて、土嚢袋４００内に、土砂Ｄを流入させる。土嚢袋４００の開口部は、大きく開き、円筒部１００の上部から、ホッパー等で隠されることが無いので、遠方から明確に確認できる。そのため、土砂Ｄの投入量を容易に安全に確認できる（図３（ｂ））。
土砂Ｄの投入完了後、土嚢袋４００の開口部を縛り、土嚢を完成させる（図３（ｃ））。
Next, earth and sand D are caused to flow into the sandbag bag 400 using a heavy machine or the like. The opening of the sandbag bag 400 opens widely and is not concealed by a hopper or the like from the top of the cylindrical portion 100, so that it can be clearly confirmed from a distance. Therefore, the amount of earth and sand D can be easily and safely confirmed (FIG. 3B).
After completion of the insertion of the sand and sand D, the opening of the sandbag bag 400 is tied to complete the sandbag (FIG. 3C).
次に、３つの牽引部２１０にワイヤを接続し、クレーン等で、土嚢製造装置１を引き上げる（図３（ｄ））。円筒部１００は、土嚢袋４００と側面で接触しているのみであるので、土嚢は、そのまま残り、土嚢製造装置１を土嚢と分離することができる。土嚢製造装置１は、次に土嚢を製造する位置に配置する。土嚢は、完成しているので、使用するまでそのまま置いておいてもいいし、個別に移動してもよい。
土嚢製造装置１の重量は、土嚢よりもはるかに軽量であるので、比較的小型のクレーン等で引き上げ動作が可能である。もし、土嚢を引き上げるとすると、２ｔ土嚢の場合、３つで計６ｔの重量を引き上げなければならず、極めて大型のクレーンが必要である。
Next, wires are connected to the three pulling sections 210, and the sandbag manufacturing apparatus 1 is pulled up with a crane or the like (FIG. 3 (d)). Since the cylindrical part 100 is only in contact with the sandbag bag 400 on the side surface, the sandbag remains as it is, and the sandbag manufacturing apparatus 1 can be separated from the sandbag. The sandbag manufacturing apparatus 1 is arranged at a position where a sandbag is manufactured next. Since the sandbag is complete, it may be left as it is until it is used, or it may be moved individually.
Since the weight of the sandbag manufacturing apparatus 1 is much lighter than that of the sandbag, it can be pulled up with a relatively small crane or the like. If the sandbag is lifted, in the case of a 2t sandbag, the weight of a total of 6t must be lifted by three, and an extremely large crane is required.
図４に沿って、円筒部１００と連結部２００の関係について、説明する。
図４（ａ）は、土嚢製造装置１の一部を上から見た図である。円筒部１００と連結部２００の関係を示している。連結部２００は、連結する円筒部１００の中心軸を通る線分上に配置している。この配置とすることで、紙面上、上下方向に対称である。土嚢完成後、牽引部２１０にワイヤを固定し、土嚢製造装置１を引き上げる際に、連結部２００が円筒部１００の中心軸を通る線分上にあることによって、偏りなく土嚢製造装置１を引き上げることができる。
図４（ｂ）は、円筒部１００と連結部２００の関係を側面から見た図である。円筒部１００の内側に配置された土嚢袋４００は、土砂Ｄが入ることで、中間部が太く、上下が比較的細い樽型の構造となる。そのため、円筒部１００と土嚢袋４００は、円筒部１００の上下方向の中間部分である接触面Ｐで圧接し、他の部分は、隙間が開いていることが多い。
土嚢製造装置１を引き上げる際、円筒部１００と土嚢袋４００との間の摩擦力が問題となる。摩擦力は、接触面Ｐで最も大きい。
The relationship between the cylindrical portion 100 and the connecting portion 200 will be described with reference to FIG.
Fig.4 (a) is the figure which looked at some sandbag manufacturing apparatuses 1 from the top. The relationship between the cylindrical part 100 and the connection part 200 is shown. The connection part 200 is arrange | positioned on the line segment which passes along the central axis of the cylindrical part 100 to connect. With this arrangement, it is symmetrical in the vertical direction on the paper surface. After the sandbag is completed, when the wire is fixed to the pulling portion 210 and the sandbag manufacturing apparatus 1 is pulled up, the connecting section 200 is on a line passing through the central axis of the cylindrical portion 100, so that the sandbag manufacturing apparatus 1 is lifted without any bias. be able to.
FIG. 4B is a side view of the relationship between the cylindrical portion 100 and the connecting portion 200. The sandbag 400 disposed inside the cylindrical portion 100 has a barrel-shaped structure with a thick middle portion and a relatively narrow top and bottom due to the inclusion of the sand and sand D. Therefore, the cylindrical part 100 and the sandbag 400 are pressed against each other at the contact surface P that is an intermediate part in the vertical direction of the cylindrical part 100, and a gap is often opened at the other part.
When pulling up the sandbag manufacturing apparatus 1, the frictional force between the cylindrical portion 100 and the sandbag bag 400 becomes a problem. The frictional force is greatest at the contact surface P.
ここで、連結部２００に対する接触面Ｐのモーメント力を考えると、摩擦力Ｎ、接触面Ｐと連結部２００の距離をＬ１とすると、モーメント力は、ＮｘＬ１で表せる。モーメント力が大きいと連結部２００に対する円筒部１００のゆがみが大きくなる。すると、円筒部１００の中心軸は、土嚢製造装置１の引き上げ方向からずれることになり、土嚢製造装置１を引き上げる際の支障となってしまう。そのため、モーメント力は、小さいほうがよい。よって、連結部２００と接触面Ｐの距離が短いほどよい。接触面Ｐは、上下方向の中間部分にあるのであるから、連結部２００の位置も同様の位置にあると好適である（図４（ｂ））。
連結部２００が円筒部１００の上部に接続されていたり、円筒部１００の下部に接続されていたりすると、連結部２００と接触面Ｐの距離はＬ２、Ｌ３となり、Ｌ１よりも大きくなる。そのため、モーメント力も大きくなり、連結部２００に対する円筒部１００のゆがみも、より大きくなってしまう（図４（ｃ））。
Here, considering the moment force of the contact surface P with respect to the connecting portion 200, if the frictional force N and the distance between the contact surface P and the connecting portion 200 are L1, the moment force can be expressed by NxL1. When the moment force is large, the distortion of the cylindrical portion 100 with respect to the connecting portion 200 increases. Then, the central axis of the cylindrical portion 100 is displaced from the pulling direction of the sandbag manufacturing apparatus 1, which becomes an obstacle when the sandbag manufacturing apparatus 1 is lifted. Therefore, it is better that the moment force is small. Therefore, the shorter the distance between the connecting portion 200 and the contact surface P, the better. Since the contact surface P is in the middle portion in the vertical direction, it is preferable that the position of the connecting portion 200 is also in the same position (FIG. 4B).
When the connecting part 200 is connected to the upper part of the cylindrical part 100 or connected to the lower part of the cylindrical part 100, the distance between the connecting part 200 and the contact surface P is L2 and L3, which is larger than L1. Therefore, the moment force is also increased, and the distortion of the cylindrical portion 100 with respect to the connecting portion 200 is also increased (FIG. 4C).
このように、本実施例の構造を使用することによって、複数の大容量の土嚢を効率よく製造することができる。
また、上下に開口する円筒部１００を用いることによって、土嚢と製造装置との接触を側面のみとすることが出来、完成した土嚢をそのままに、土嚢製造装置１を土嚢と分離することが出来、容易に次の土嚢製造にかかることが出来る。
また、複数の円筒部１００をもつことで、複数の土嚢を同時に製造することができる。
また、連結部２００が、連結する前記円筒部の中心軸を通る線分上にあることで、円筒部１００をバランスよく引き上げることが出来る。
また、連結部２００が、連結する前記円筒部を軸方向に３分割した際の、中段部分に連結されていることによって、連結部２００と接触面Ｐとの距離を小さくすることが出来、引き上げる際の連結部２００と接触面Ｐとの間のモーメント力を小さくし、土嚢製造装置１の引き上げ時の連結部２００と円筒部１００のゆがみを小さくすることが出来る。
また、円筒部１００が、シームレス鋼管で構成されていることによって、接触面Ｐの圧力に対して均等の強度を持つことが出来、土嚢製造装置１の耐久性を向上させることが出来る。
また、円筒部１００が、３つで構成されていることによって、土嚢製造装置１を引き上げる際のワイヤも３本とすることが出来、他の本数よりも安定して土嚢製造装置１を引き上げることが出来る。
また、隣接する円筒部１００部同士が、円筒部１００の底部で接続される補強部で補強されていることによって、円筒部１００同士の間隔のゆがみを防止することが出来る。
また、円筒部１００の上部開口部付近に土嚢開口部端部を固定する紐用リング１１０を持つことによって、土嚢袋４００に土砂Ｄを流入させる際に開口部の大きさを安定して維持できる。
Thus, a plurality of large-capacity sandbags can be efficiently manufactured by using the structure of this embodiment.
Moreover, by using the cylindrical part 100 opened up and down, the contact between the sandbag and the manufacturing apparatus can be made only on the side surface, and the sandbag manufacturing apparatus 1 can be separated from the sandbag while leaving the completed sandbag as it is. The next sandbag can be easily manufactured.
Moreover, a plurality of sandbags can be manufactured simultaneously by having a plurality of cylindrical portions 100.
Moreover, the cylindrical part 100 can be pulled up with sufficient balance because the connecting part 200 is on a line segment passing through the central axis of the cylindrical part to be connected.
Further, since the connecting portion 200 is connected to the middle portion when the cylindrical portion to be connected is divided into three in the axial direction, the distance between the connecting portion 200 and the contact surface P can be reduced and pulled up. The moment force between the connecting portion 200 and the contact surface P can be reduced, and the distortion of the connecting portion 200 and the cylindrical portion 100 when the sandbag manufacturing apparatus 1 is pulled up can be reduced.
Moreover, since the cylindrical part 100 is comprised with the seamless steel pipe, it can have an equal intensity | strength with respect to the pressure of the contact surface P, and can improve the durability of the sandbag manufacturing apparatus 1. FIG.
Moreover, since the cylindrical part 100 is comprised by three, the wire at the time of pulling up the sandbag manufacturing apparatus 1 can also be made into three, and pulls up the sandbag manufacturing apparatus 1 more stably than another number. I can do it.
In addition, since the adjacent cylindrical portions 100 are reinforced by the reinforcing portion connected at the bottom of the cylindrical portion 100, the interval between the cylindrical portions 100 can be prevented from being distorted.
In addition, by having the string ring 110 that fixes the end of the sandbag opening near the upper opening of the cylindrical portion 100, the size of the opening can be stably maintained when the sand and sand D is allowed to flow into the sandbag 400. .
本発明に係る土嚢製造装置は、複数の土嚢を同時に製造する土嚢製造装置についての産業上の利用可能性は大きいと解する。
It is understood that the sandbag manufacturing apparatus according to the present invention has a large industrial applicability for a sandbag manufacturing apparatus that simultaneously manufactures a plurality of sandbags.
