Description
本発明は、土嚢の利用方法に関するものである。 The present invention relates to a method for using a sandbag.
従来より、土木資材として、麻袋の中に土砂を詰め込んだ土嚢が土木現場などで広く利用されている。 Conventionally, sandbags filled with sand and sand in hemp bags have been widely used as civil engineering materials at civil engineering sites.
この土嚢は、雨水の浸入や土砂崩れなどを防止するために積み上げられて使用されるものであり、緊急時等に一時的に使用されるものであった。 The sandbags are used by being piled up to prevent rainwater intrusion and landslides, and are temporarily used in an emergency or the like.
従来の土木資材としての土嚢は、麻袋に土砂を詰め込んだ構成となっているために、変形が容易である程度の重量があることから、一時的に積み上げて暫定的に使用するには適したものであった。 The conventional sandbag as a civil engineering material is a structure in which hemp bags are filled with earth and sand, so it is easy to deform and has a certain amount of weight, so it is suitable for temporary accumulation and temporary use Met.
しかしながら、従来の土嚢は、長期間にわたって使用すると経時的に変形が進むことから、長期間にわたって恒久的に使用するには適していなかった。 However, conventional sandbags are not suitable for permanent use over a long period of time, as deformation over time occurs when used over a long period of time.
また、従来の土嚢は、使用後に産業廃棄物として廃棄処理されており、有効に再利用されていなかった。 Further, conventional sandbags are disposed of as industrial waste after use, and have not been effectively reused.
そこで、請求項１に係る本発明では、土嚢の利用方法において、通水性を有しない袋本体に窓を形成した袋に水硬性を有する中込材を充填するとともに前記中込材に吸水性及び導水性を有する繊維状材料を添加した土嚢を設置した後に窓から雨水が浸入することで中込材を硬化させて使用することにした。
Therefore, in the present invention according to claim 1, in the sandbag utilization method, a bag having a window formed in a bag body that does not have water permeability is filled with a hydraulic insert, and the intermediate insert is water-absorbing and water-conducting. After installing sandbags with the addition of fibrous materials having rainwater, it was decided to use the cured material by hardening the rainwater from the windows .
また、請求項２に係る本発明では、土嚢の利用方法において、前記袋の通水性を有する窓を通水性を有しない素材で着脱自在に被覆することにした。 Moreover, in this invention which concerns on Claim 2, it decided to coat | cover the window which has water permeability of the said bag with the raw material which does not have water permeability so that attachment or detachment is possible.
また、請求項３に係る本発明では、土嚢の利用方法において、前記土嚢を使用後に回収し、硬化した中込材を海中に設置して藻の繁殖を促成する人工藻礁として再利用することにした。 Further, in the present invention according to claim 3, in the method of using the sandbag, the sandbag is collected after use, and the hardened insert is placed in the sea and reused as an artificial alga reef that promotes the growth of algae. did.
そして、本発明では、以下に記載する効果を奏する。 And in this invention, there exists an effect described below.
すなわち、本発明では、土嚢の利用方法において、通水性を有する袋に水硬性を有する中込材を充填した土嚢を設置した後に通水して中込材を硬化させて使用することにしているために、長期間にわたって使用しても変形することがなくなり、止水効果が得られ、恒久的に使用することができる。 That is, in the present invention, in the sandbag utilization method, since a sandbag filled with hydraulic intermediate filling material is installed in a bag having water permeability, water is passed through and the intermediate filling material is cured and used. Even if it is used for a long period of time, it will not be deformed, a water stop effect will be obtained, and it can be used permanently.
また、土嚢を使用後に回収し、硬化した中込材を他の土嚢や人工藻礁として再利用することで、資源を長期間にわたって有効に利用することができる。 Moreover, resources can be effectively utilized over a long period of time by collecting sandbags after use and reusing the hardened intermediate material as other sandbags or artificial algae.
以下に、本発明に係る土嚢の利用方法の具体的な構成について図面を参照しながら説明する。 Hereinafter, a specific configuration of the sandbag using method according to the present invention will be described with reference to the drawings.
本発明に係る土嚢は、通水性を有する袋の内部に水硬性を有する中込材を充填したものであり、たとえば、上部に開口を有する袋の内部に中込材を詰め込んで、上部の開口を紐やミシンや溶着等で封止したものである。 The sandbag according to the present invention is a bag in which a water-permeable bag is filled with a hydraulic medium-filling material. Sealed with a sewing machine or welding.
本発明に係る土嚢では、袋が、一部又は全部に通水性を有している。この袋は、麻袋等のように織成された袋で、全部に通水性を有しているものでもよく、また、ビニール袋等のように通水性を有していない素材で形成した袋本体に矩形貫通状の窓を形成し、その窓に網を袋本体の内側から張設（貼着）して、一部に通水性を有するように構成したものでもよい。 In the sandbag according to the present invention, the bag has water permeability partially or entirely. This bag is a woven bag such as a hemp bag and may be water-permeable as a whole, or a bag body formed of a material that does not have water permeability such as a plastic bag. A rectangular penetrating window may be formed in the window, and a net may be stretched (attached) to the window from the inside of the bag body so that part of the window has water permeability.
また、本発明に係る土嚢では、袋の内部に詰め込まれた中込材が、土砂ではなく、硬化前のセメント等の水硬性を有する粒子を一部又は全部に含んでいる。 In the sandbag according to the present invention, the filling material packed in the bag contains not only the earth and sand but also a part or all of the particles having hydraulic properties such as cement before hardening.
袋の内部に詰め込まれた中込材は、水分と反応して硬化（固化）する水硬性を有する物質の粒子を含有させている。たとえば、中込材として、粉末状のスラグ１００重量部と粉末状のセメント３０重量部との混合物を袋の内部に詰め込んでいる。なお、袋の内部には、重金属の流出を防止するために重金属固化材を添加してもよく、スサやセルロースなどの繊維状材料や有機材料を添加してもよく、さらには、使用済みの土嚢で固化した中込材を破砕又は粉砕したものを骨材や増量材として添加してもよい。なお、中込材としては、０．０１μｍ以上０．５ｍｍ以下の粒体であって０．５μｍ以下の微粒子を５重量％以上含まれているものを用いている。また、袋の内部にスラグとセメントを詰め込んだ場合には、１００重量部〜５００重量部の水と反応することで固化し、重量が倍以上に増大する。 The filling material packed in the bag contains particles of a substance having hydraulic properties that reacts with moisture and hardens (solidifies). For example, as a filling material, a mixture of 100 parts by weight of powdered slag and 30 parts by weight of powdered cement is packed in the bag. In addition, a heavy metal solidifying material may be added to the inside of the bag in order to prevent the heavy metal from flowing out, a fibrous material such as soot and cellulose, or an organic material may be added. You may add what was crushed or grind | pulverized the embedding material solidified with the sandbag as an aggregate or an extender. In addition, as an interstitial material, the thing of 0.01 micrometer or more and 0.5 mm or less particle | grains and 0.5 micrometer or less microparticles | fine-particles are used 5 weight% or more is used. Moreover, when slag and cement are packed in the inside of a bag, it solidifies by reacting with 100 weight part-500 weight part water, and a weight increases more than double.
以上に説明したように、上記土嚢は、袋が通水性を有し、中込材が水硬性を有することから、設置後の自然な通水や強制的な通水によって袋の内部の中込材を硬化（固化）させることができ、長期間にわたって使用しても変形することがなく、恒久的に使用することができる。 As explained above, the sandbag has a water permeability in the bag, and the insert material has hydraulic properties. It can be cured (solidified) and can be used permanently without being deformed even when used over a long period of time.
特に、上記土嚢では、中込材に吸水性及び導水性を有する繊維状材料を添加することで、中込材に含有された繊維状材料によって、固化する際に水分を内部に良好に導くことができ、袋の内部の中込材を均一に硬化（固化）させることができるとともに、水の分散が適当となるために水和反応の速度や固化反応による内部ストレスの発生を抑制することができてクラックの発生がなく、固化した際の強度を増大させることができる。 In particular, in the sandbag, by adding a fibrous material having water absorption and conductivity to the interstitial material, the fibrous material contained in the interstitial material can lead moisture well to the inside when solidifying. In addition to being able to uniformly cure (solidify) the inside material of the bag and to disperse water appropriately, the rate of hydration reaction and the generation of internal stress due to the solidification reaction can be suppressed, and cracks can occur. It is possible to increase the strength when solidified.
また、上記土嚢では、中込材が水分と反応して水和体を生成することで重量が増大することで、使用前（硬化前）においては重量が軽く、使用前の運搬作業や積み上げ作業を容易なものとすることができる。 Moreover, in the above sandbags, the weight increases because the intercalation material reacts with moisture to form a hydrate, so that the weight is light before use (before curing), and transportation work and stacking work before use It can be easy.
さらに、上記土嚢では、袋の通水性を有する部分を通水性を有しない素材で着脱自在に被覆することで、袋の内部に水分が浸入するのを防止することができ、使用前に長期間にわたって備蓄しておくことができる。 Furthermore, in the sandbag, the water-permeable portion of the bag is detachably covered with a non-water-permeable material, so that moisture can be prevented from entering the bag, and the bag can be used for a long time before use. You can stockpile over.
本発明に係る土嚢は、図１に示すように、まず、通水性を有する袋に硬化前（硬化していない状態）の水硬性を有する中込材を充填することで自硬性土嚢を製造する。その後、自硬性土嚢は、設置現場に設置され使用される。なお、自硬性土嚢は、予め袋に中込材を詰め込んで開口を封止した状態の物（完成品）を設置現場に運搬して設置してもよく、袋と中込材を設置現場にそれぞれ運搬し、設置現場において袋の内部に中込材を詰め込み、袋の開口を紐等で結んでから、所定位置に設置してもよい。また、 As shown in FIG. 1, the sandbag according to the present invention is manufactured by first filling a water-permeable bag with a filling material having hydraulic properties before hardening (not hardened). Thereafter, the self-hardening sandbag is installed and used at the installation site. In addition, self-hardening sandbags may be installed by transporting the bag (filled product) in a state in which the filling material is stuffed into the bag in advance and sealing the opening (finished product) to the installation site. Then, the filling material may be packed inside the bag at the installation site, and the bag opening may be tied with a string or the like, and then installed at a predetermined position. Also,
この自硬性土嚢は、使用により雨水が袋の内部に浸入することで、或いは、強制的に水を袋の内部に侵入させることで、中込材が硬化する。これにより、自硬性土嚢は、長期間にわたって使用しても変形することがなく、恒久的に使用することができる。 This self-hardening sandbag is hardened by the intrusion of rainwater into the bag by use, or by forcing water to enter the bag. Thereby, a self-hardening sandbag does not deform | transform even if it uses over a long period of time, and can be used permanently.
自硬性土嚢は、使用後に回収し、硬化した中込材をそのまま或いは粉砕して、再利用することができる。 The self-hardening sandbag can be reused after being used or recovered by pulverizing the hardened intermediate material.
回収した自硬性土嚢は、硬化した中込材を袋に充填することで、非自硬性土嚢を製造することができる。この非自硬性土嚢は、従来の土嚢と同様に設置されて使用される。 The recovered self-hardening sandbag can be made into a non-self-hardening sandbag by filling the bag with a hardened insert. This non-self-hardening sandbag is used in the same manner as a conventional sandbag.
また、回収した自硬性土嚢（非自硬性土嚢を回収したものでもよい）は、硬化した中込材をそのまま資材として利用することもできる。その場合に、硬化した中込材をそのまま或いは硬化した中込材を骨材として成型（製造）したものを海中に設置して藻の繁殖を促成する人工藻礁として利用することもできる。なお、人工藻礁として利用する場合には、所定期間海中において海底に接触させることなく吊設して藻と種子を付着させた後に海底に設置させることで、藻の繁殖を良好なものとすることができる。 In addition, the recovered self-hardening sandbag (which may be a non-self-hardening sandbag may be recovered) can be directly used as a material. In this case, the cured intermediate powder can be used as an artificial algae reef for promoting the growth of algae as it is or by molding (manufacturing) the cured intermediate powder as an aggregate. In addition, when used as artificial algae reefs, the algae grow well by suspending them without contacting the seabed for a predetermined period of time and attaching them to the seabed after attaching the algae and seeds. be able to.
なお、自硬性土嚢や非自硬性土嚢は、販売してもよく、また、レンタルやリースにて貸与してもよい。貸与した場合には、自硬性土嚢や非自硬性土嚢が不法投棄されたり不特定業者に拡散してしまうのを防止することができ、国や地方自治体等の管理を容易なものとすることができる。 In addition, a self-hardening sandbag and a non-self-hardening sandbag may be sold, and may be lent by rental or lease. When loaned, self-hardening sandbags and non-self-hardening sandbags can be prevented from being illegally dumped or spread to unspecified contractors, making it easier to manage the national and local governments. it can.
以上に説明したように、通水性を有する袋に水硬性を有する中込材を充填した土嚢を設置した後に通水して中込材を硬化させて使用することによって、土嚢を長期間にわたって使用しても変形することがなくなり、止水効果が得られ、恒久的に使用することができる。 As explained above, the sandbag is used over a long period of time by setting the sandbag filled with hydraulic interstitial material in the water-permeable bag and then passing the water through to cure the medial material. Can also be used permanently.
また、土嚢を使用後に回収し、硬化した中込材を他の土嚢や人工藻礁として再利用することで、資源を長期間にわたって有効に利用することができる。 Moreover, resources can be effectively utilized over a long period of time by collecting sandbags after use and reusing the hardened intermediate material as other sandbags or artificial algae.
