Description

本発明は河川、港湾、歩道、法面などを形成補修するために敷設する鉱物質状の多孔質に焼結させた多孔質構造の敷設材に関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laying material having a porous structure sintered to a mineral-like porous material for laying and repairing rivers, ports, sidewalks, slopes, and the like.
これまでこれら河川等の形成補修は、コンクリート打ち、コンクリートブロック積み、アスファルト打ちなどによる施工手段が一般的であった。   Until now, the formation and repair of these rivers, etc., were generally carried out by concrete casting, concrete block pile, asphalt driving, and the like.
これら手段による構築構造は、いずれも生物の棲息、生育を妨げる殺風景な環境を造り出しており、加えて大気、水質汚染が広がりつつある昨今の自然環境をも考慮して、河川等を取りまく自然環境を生物との共存を前提に蘇らせることが叫ばれている。   All of these construction structures create a scenic environment that hinders the inhabitation and growth of living organisms, and in addition to the natural environment surrounding rivers, etc., taking into account the recent natural environment where air and water pollution are spreading. It is screamed to resurrect on the premise of coexistence with living things.
そこで近年、特開2000−95580号公報(特許文献1)に記載されているような廃棄材としてのクリンカーアッシュ(石炭灰) 、砕石場から出る水洗廃泥などの粘土材を配合し、これに同じく廃棄材としての剪定屑などの(木炭粉) を加配して成形した後、焼成することによって連通孔を有する多孔質構造の塊に形成する固形材が開発され、この固形材を堤防、河床の形成補修等に用いられることが試みられている。
特開2000−95580号公報
Accordingly, in recent years, clay materials such as clinker ash (coal ash) as a waste material and washing waste mud from a quarry have been blended as described in JP-A-2000-95580 (Patent Document 1). Similarly, solid materials that are formed by adding (charcoal powder) such as pruning waste as waste material and forming them into porous masses with communication holes by firing are developed. Attempts have been made to use it for the repair of formation.
JP-A-2000-95580
しかし、この固形材は、前記廃棄材により構成し焼成させて成るため、全体の比重が極めて軽く、河川等の改修材としては定着性がなく容易に移動する。そのため水流のある河川、港湾などでは少しの増水または波により流失決壊し、歩道などでは路面が凸凹となる等の問題があった。   However, since this solid material is composed of the waste material and fired, it has a very low specific gravity as a whole and easily moves as a repair material for rivers and the like without fixability. For this reason, there has been a problem that a river or a harbor with a water flow breaks down due to a slight increase in water or a wave, and a road surface becomes uneven on a sidewalk or the like.
また、焼成形成過程において、1, 200°C前後の高熱で燒結させるため、固形材の厚みが50・程度を超える比較的大きなものになると、中心部が連通孔を形成するまで焼結させるとき、表面部がガラス状に熔解して連通孔は潰れ通気性のない固形材が形成される。逆に表面部分を正常な多孔質構造に焼結させるとき、中心部が未だ多孔質構造に成りきらない生煮えの脆弱状態で固形材が形成される。即ち、固形材の厚みが50mm程度を超える大きなものは、全体を多孔質構造に焼結することが難しく、重量素材の混合によりさらに難しくなるなどの問題も抱えていた。   In addition, in the sintering process, since the solid material is relatively large, having a thickness of more than about 50.degree., Since the sintering is performed at a high temperature of about 1,200.degree. Then, the surface portion is melted into a glass state, and the communication hole is crushed to form a solid material having no air permeability. Conversely, when the surface portion is sintered into a normal porous structure, the solid material is formed in a weakly boiled state in which the central portion has not yet formed the porous structure. That is, a large solid material having a thickness exceeding about 50 mm has a problem that it is difficult to sinter the whole into a porous structure, and it becomes more difficult to mix a heavy material.
この発明は上記課題を解決するため、中心部に比重の大きい岩石、金属など不燃性物質から成る塊状の芯材を配し、それ自体多孔質のクリンカーアッシュを50〜80重量%に、繋ぎ材としての粘土を20〜50重量%を加え加水混合して成る素材で、比重の大きい岩石、金属など不燃性物質から成る塊状の芯材を包んで、素材層を最大肉厚25mmで中心部に比重の大きい芯材を配した状態で成形し、1, 150℃前後の高温で焼成することにより、素材層に多数の連通孔を目詰まりなく効率よく形成させた多孔質構造の固形物を形成して敷設材とすることを提案する。   In order to solve the above-mentioned problems, the present invention arranges a massive core material made of a nonflammable substance such as rock or metal having a large specific gravity at the center, and adds 50 to 80% by weight of porous clinker ash itself and a connecting material. 20 to 50% by weight of clay is added and mixed with water, and the material is wrapped around a massive core made of non-combustible materials such as rocks and metals with high specific gravity. Formed with a core material having a large specific gravity, and fired at a high temperature of about 1,150 ° C to form a solid material with a porous structure that efficiently formed many communication holes in the material layer without clogging It is proposed to use it as a laying material.
また、請求項2のように前記素材に比重が1.5以上の重量調整材として粒径5〜0.6mmのスラグ、岩石粒などの不燃性物質から成る調整骨材20〜40重量%を加え加水混合して成る素材で、不燃性物質から成る塊状の芯材を包むことにより、敷設材の重量をさらい大きくして安定した据え付けが得られると共に、調整骨材を加えた所定の粒径、割合に加え最大肉厚25mmにより調整骨材の加入にも拘わらず、敷設材の素材層に目詰まりのない高効率の多孔質構造を形成させることができる。   Further, as described in claim 2, as the weight adjusting material having a specific gravity of 1.5 or more, 20 to 40% by weight of an adjusted aggregate made of a non-combustible material such as slag or rock having a particle size of 5 to 0.6 mm is added to the material. By adding a water-mixed material and wrapping a massive core made of non-combustible material, the weight of the laying material can be increased and stable installation can be obtained. Due to the maximum thickness of 25 mm in addition to the ratio, a highly efficient porous structure without clogging can be formed in the material layer of the laying material despite the addition of the adjusted aggregate.
各原料を上記のような粒径および混合割合にて加水混合した素材で、芯材を包んで成形焼成することにより、多数の連通孔組織を有するクリンカーアッシュにより目詰まりのない多孔質構造を効率よく容易に形成させることができる。しかも敷設材の全体比重を、施工個所の条件に応じて芯材の比重密度及び大きさに加え、岩石粒などの調整骨材の重量比を加減することにより、敷設材の施工個所での定着を確実にして増水などにより流失することを防ぐと共に、多孔質構造の連通孔による水中の汚染物質を吸着濾過する浄化作用および生物の棲息、生育を助長する作用を永く維持する。   The core material is wrapped and molded and fired with a raw material obtained by mixing each raw material with the above-mentioned particle size and mixing ratio, so that clinker ash having a large number of communicating pore structures can efficiently produce a porous structure without clogging. It can be easily formed well. Moreover, by adding the overall specific gravity of the laying material to the specific gravity density and size of the core material according to the conditions of the construction site, and adjusting the weight ratio of the adjusted aggregate such as rock grains, the laying material is fixed at the construction site To prevent the water from being washed away due to increased water and the like, and to maintain the purifying action of adsorbing and filtering contaminants in water and the action of promoting the inhabitation and growth of living organisms through the porous communication holes for a long time.
また、請求項3のようにクリンカーアッシュ、粘土、比重が1.5以上の岩石、スラグなどの不燃性鉱石材から成る調整骨材としての粒体に、さらに連通孔形成材としての可燃性物質10〜20重量%を加えて加水混合した素材により、芯材を包み成形焼成して成る敷設材を提案し、この可燃性物質として、定屑の木炭粉などの可燃性物質から成る連通孔形成材を加えて成形焼成して成る敷設材をも提案する。 In addition, as an adjusting aggregate made of non-combustible ore such as clinker ash, clay, rock having specific gravity of 1.5 or more, slag, and the like, a flammable substance as a communication hole forming material the material was hydrolyzed mixed with 10 to 20 wt%, proposes laying material formed by molding baked wrapped core, as the combustible material, communication holes consisting of combustible materials, such as charcoal powder pruning Teikuzu We also propose a laying material that is formed and fired by adding a forming material.
焼成過程において焼却する連通孔形成材により、素材層に緻密に連通する連通孔が形成され、その表面積がより増大して水質浄化および自然の生態系維持作用が拡大すると共に、比重の大きい安定性のある敷設材に緻密な多孔質構造を簡易に形成することができる。   The communication hole forming material that is incinerated during the baking process forms communication holes that are densely connected to the material layer, increasing the surface area, increasing the water purification and natural ecosystem maintenance effects, and stabilizing the specific gravity. A dense porous structure can be easily formed on a laying material having a structure.
敷設材の芯材までの素材層は、芯材およびその輻射熱作用により完全に連通する通気性の良い緻密な多孔質構造を容易に焼成形成することができ、その上敷設材の重量を芯材の大きさにより調整することができ、安定性を倍増させて一層確実な不動敷設が得られる。   The material layer up to the core material of the laying material can easily form a dense porous structure with good permeability that is completely connected by the core material and its radiant heat effect. The stability can be doubled, and a more reliable immovable installation can be obtained.
この発明の敷設材は上記で説明した構成から、自然の生態系を維持するのに適した多数の連通孔から成る多孔質構造を有する敷設材の安定した据え付けを図るため、芯材及び重量調整用骨材の多寡を加減し、施工する状況に応じて敷設材全体の重量を容易に加減して混合し芯材を包み焼成するものであるが、各原料の粒径、割合に加え、調整骨材の粒径、割合を前記する所定範囲内で調整して焼成実験することにより、安定の良い重量構造に加え、素材層における多孔質構造形成の効率を最良に上げる粒径、割合に到達した点に特徴があり、単に敷設材自体の重量を増大させるための芯材装填構造に止まるものではないため、比較的大きな敷設材にあっても、全体に均一な目詰まりのない多孔質構造を確実に焼成形成することが簡易となり、併せて重量を増加して焼成することも容易となる。   The laying material of the present invention has a core material and a weight adjuster for the stable installation of the laying material having a porous structure composed of a large number of communication holes suitable for maintaining a natural ecosystem, from the configuration described above. The amount of aggregate used is adjusted, and the weight of the entire laying material is easily adjusted according to the construction conditions, mixed, wrapped and baked, but adjusted in addition to the particle size and proportion of each raw material. By adjusting the particle size and ratio of the aggregate within the above-mentioned predetermined range and conducting a firing experiment, in addition to a stable weight structure, the particle size and ratio that maximize the efficiency of porous structure formation in the material layer are reached. It is characterized by the fact that it is not limited to a core material loading structure simply to increase the weight of the laying material itself, so even for relatively large laying materials, a porous structure without uniform clogging throughout It is easy to reliably form by firing, It was it is also easy to firing to increase the weight.
これによって河川等での施工において、敷設材は組置きまたは積み敷くなどの簡易な敷設施工手段により不動に安定良く敷設することができ、港湾、河川においては、波濤または増水により敷設材が容易に流失して決壊する虞れがないため、再度補修しなければならない等のコストを削減することができると共に、多孔質構造による自然の生態系に調和する環境を永く維持することができる。   As a result, in the construction of rivers, etc., the laying materials can be immovably and stably laid by simple laying construction means such as assembling or laying. Since there is no risk of being washed away and destroyed, it is possible to reduce costs such as having to repair again and to maintain an environment that is in harmony with the natural ecosystem due to the porous structure for a long time.
また遊歩道などでは、重量を付加した多孔質構造の敷設材で安定した敷き詰めが得られ妄りに移動することがないため、歩道面が凹凸に片寄らなくなり、且つ滑らない歩き易い路面を維持することができる。   In addition, on promenades, etc., a stable laying material with a porous structure having added weight can be obtained and it does not move unnecessarily, so that the sidewalk surface is not biased to unevenness, and it is possible to maintain a slippery and easy-to-walk road surface. it can.
この発明の実施の形態を説明すると、火力発電所より大量に排出されるクリンカーアッシュ(石炭灰) のもつ連通孔組織を利用して、廃材として用途の少ない粒径が3mm以下のクリンカーアッシュ50〜80重量%と、各種産業から排出される粘土質材の水洗粘泥から成る繋ぎ材としての粘土20〜50重量%を配合し、これに重量調整骨材として嵩比重が1.5以上の粒径5〜0.6mmの岩石粒を20〜40重量%を加水混合して成る素材で、比重の大きい岩石、金属など不燃性物質から成る塊状の芯材を包んで、素材層が最大肉厚で25mmとして中心部に比重の大きい芯材を配した状態で成形し、1, 150℃前後の高温で焼成することにより、素材層に多数の連通孔を効率よく形成させた多孔質構造の固形物を形成して比重の大きい多孔質敷設材を構成する。   According to an embodiment of the present invention, the clinker ash (coal ash) discharged from a thermal power plant in large quantities is used as a waste material, and the clinker ash having a small particle size of 3 mm or less is used as a waste material. 80% by weight and 20 to 50% by weight of clay as a binding material composed of washed mud of clay materials discharged from various industries are mixed, and the particles having a bulk specific gravity of 1.5 or more are used as weight adjusting aggregates. A material made by mixing 20 to 40% by weight of rock grains having a diameter of 5 to 0.6 mm with water, wrapping a massive core made of a non-combustible substance such as rock or metal having a large specific gravity, and the material layer having a maximum thickness In a state where a core material having a large specific gravity is arranged in the center portion and the material is fired at a high temperature of about 1,150 ° C., a solid structure having a porous structure in which a large number of communication holes are efficiently formed in the material layer. Forming things and high specific gravity A porous laying material.
粘土の配合でクリンカーアッシュの連通孔による通気機能を低下させるため、重量比でクリンカーアッシュ50〜80%、粘土20〜50%が好ましく、粘土の質により焼成された敷設材の強度を勘案してその割合を加減するもので、粘土の割合を可及的少なくして焼成することが望ましい。   Clinker ash is preferably 50 to 80% by weight and 20 to 50% of clay in weight ratio in order to reduce the ventilation function of the clinker ash through the pores in the composition of the clay. It is desirable to reduce the proportion of the clay, and it is desirable to perform the calcination with the proportion of the clay as small as possible.
芯材は敷設材自体の重量を大きくするばかりでなく、敷設材の外形を可成り大きくすることができるため、安定した据え付けが期待することができ、活用分野も拡大する。 なお、重量調整骨材としての岩石粒は、焼成された敷設材の重量による安定性を確実にするためには、均一分散が必要であることから粒径を5〜0.6mmとして混合するもので、可及的比重の大きい調整骨材であることが望ましい。   The core material not only increases the weight of the laying material itself, but also allows the outer shape of the laying material to be considerably increased, so that stable installation can be expected and the field of application is expanded. The rock grains as the weight adjusting aggregate are mixed with a particle size of 5 to 0.6 mm because uniform dispersion is necessary to ensure the stability of the fired laying material by weight. Therefore, it is desirable that the adjusted aggregate has as large a specific gravity as possible.
この敷設材1を用いた河川での施工例を図2〜4に基づいて説明すると、図2に示すように、増水時には浸水する河川敷などのコンクリート打ち敷面の枡枠6, 6内に敷設材1, 1を直接詰め敷き、また敷設材1, 1を充填した蛇篭5を詰め敷いて改修施工し、コンクリート打ち敷面に不動の多孔質構造面を形成する。   An example of construction in a river using this laying material 1 will be described with reference to FIGS. 2 to 4. As shown in FIG. The material 1,1 is directly laid, and the gabion 5 filled with the laying material 1,1 is laid and repaired to form an immovable porous structure surface on the concrete laid surface.
図3では、敷設材1, 1を充填した蛇篭5, 5を、河川の河床部7に敷き詰めて改修施工し、河床部7に不動の多孔質構造を形成する。   In FIG. 3, gabions 5, 5 filled with the laying materials 1, 1 are spread over a riverbed 7 of a river and repaired to form an immovable porous structure in the riverbed 7.
また図4に示すように、湿原、公園などの小川の土手を改修補強するため、止め枠9を施した土手の補修個所8に網体10を敷き添わせ、これに敷設材1, 1を積み入れた後、網体10で包む状態に敷設材1, 1を覆い包み止めて改修施工し、生物の棲息、成育並びに透水浄化を促進する多孔質構造の土手面を形成し、永く確保するものである。   As shown in FIG. 4, in order to rehabilitate and reinforce a bank of a stream such as a bog or a park, a net 10 is laid along a repair portion 8 of a bank provided with a retaining frame 9, and the laying materials 1, 1 are attached thereto. After loading, wrapping and laying the laying materials 1 and 1 in a state of being wrapped in the net 10 and rehabilitating them, forming a bank with a porous structure that promotes inhabitation, growth and purification of water permeation, and secures it for a long time Things.
その実施例を図1を用いて説明すると、クリンカーアッシュ(石炭灰) 50〜80重量%、粘土およびベントナイト20〜50重量%の配合に対し、比重が1.5以上の重量調整骨材としての岩石粒3, 3を20〜40重量%加え、さらに焼成時に高い熱量を発する炭化物を10〜20重量%添加しボール状に成形乾燥させた後、積極的な空気供給で焼成することにより、炭化物が燃焼して形成された連通孔2, 2で多孔質構造の敷設材1を構成することができ、この炭化物の高い燃焼エネルギーにより焼成を助け少ない燃料で焼成することができる。   The embodiment will be described with reference to FIG. 1. The blending of clinker ash (coal ash) 50 to 80% by weight, clay and bentonite 20 to 50% by weight has a specific gravity of 1.5 or more as a weight adjusting aggregate. 20 to 40% by weight of rock grains 3, 3 and 10 to 20% by weight of a carbide that generates a high calorific value at the time of firing are added and dried into a ball shape. The laying material 1 having a porous structure can be constituted by the communication holes 2 and 2 formed by burning. The high combustion energy of the carbide assists calcination and enables calcination with a small amount of fuel.
焼成過程で連通孔を形成させる有機物質は、前記炭化物のほか、単繊維有機物としてパルプスラッジがあり、焼成によって素材層組織内に微細な連通孔を形成することができる。また細粒有機物として鋸木屑、麸、おから等があり、これら有機物質を前記クリンカーアッシュ等に加え、この混合素材に加水混合し焼成することにより、燃焼炭化したこれら有機物により互いに連通する通気孔を形成する。   The organic substance that forms the communication hole in the firing process includes pulp sludge as a single fiber organic material in addition to the above-mentioned carbide, and a fine communication hole can be formed in the material layer structure by firing. Also, fine-grained organic substances include sawdust, fu, okara, and the like. These organic substances are added to the clinker ash, etc., mixed with this mixed material and baked, and the air holes communicated with each other by the combustion and carbonized organic substances. To form
この実施例における素材の混合、成形、焼成の工程は、下記の表に示したように粒径5〜0.6mmとした比重2.75のグレー色骨材(松阪興産(株))または比重3.60の黒色骨材(ES200S) から成る重量調整骨材を加えた各原料を秤量してミキサーにて混合加水攪拌して成る素材を、土練機にて径3mmの円柱状に押し出し、3mmの長さに切断しボール状に整形乾燥させた後、各々配合別に耐火容器に収容し、これをガス炉内に積み入れて、3時間をかけ1, 150°Cまで温度を上げ20分おいた後に焼成を止め、15時間自然冷却して取り出したもので、いずれも茶褐色の中心部までポーラス状の連通孔を形成した強度ある多孔質構造の素材を構成することができた。   The steps of mixing, forming, and firing the raw materials in this example were performed using a gray-colored aggregate (Matsusaka Kosan Co., Ltd.) with a specific gravity of 2.75 and a specific gravity of 5 to 0.6 mm as shown in the table below. Each raw material to which the weight-adjusted aggregate made of 3.60 black aggregate (ES200S) was added was weighed, mixed and agitated and mixed with a mixer, and the material was extruded into a cylindrical shape having a diameter of 3 mm using a kneading machine. After cutting to a length of 3 mm and shaping and drying into a ball shape, each was stored in a refractory container for each formulation, and this was loaded into a gas furnace, and the temperature was raised to 1,150 ° C over 3 hours and increased for 20 minutes. After the sintering, the baking was stopped, the material was naturally cooled for 15 hours, and was taken out. In each case, a material having a strong porous structure in which a porous communicating hole was formed up to a brownish central portion could be formed.
図1を用いて他の一つの実施例を説明すると、クリンカーアッシュ50〜80重量%と、繋ぎ材としての粘土20〜50重量%を配合し、これに重量調整骨材として嵩比重が1.5以上の粒径5〜0.6mmの岩石粒3,3を20〜40重量%、可燃性物質の炭化物10〜20%を加えて加水混合した素材で、不燃性物質として比重が1.5以上と大きい岩石から成るボール状の芯材4の表面を、約25mmの肉厚で覆い包んで整形乾燥させた後、焼成することにより、芯材4の表面を全体に亘り完全に連通する均一な多孔質構造の素材層で一体形成されて敷設材1を構成する。   Referring to FIG. 1, another embodiment will be described. Clinker ash of 50 to 80% by weight and clay of 20 to 50% by weight as a linking material are blended. A material obtained by adding 20 to 40% by weight of rock grains 3, 3 having a particle size of 5 to 0.6 mm and having a particle size of 5 or more and 10 to 20% by weight of a flammable substance carbide, and having a specific gravity of 1.5 as a nonflammable substance. The surface of the ball-shaped core material 4 made of a large rock as described above is covered with a thickness of about 25 mm, shaped, dried, and then baked, whereby the surface of the core material 4 is completely communicated over the entire surface. The laying material 1 is integrally formed of a material layer having a simple porous structure.
なお、素材において連通孔2を形成するための炭化物(可燃性物質) を混合せず、クリンカーアッシュがもつ通気孔組織のみによっても多孔質構造の素材層で芯材を一体に包んだ敷設材1を焼成することはできるものである。また繋ぎ材としてのベントナイトについても同様に、これを混合せず粘土のみの配合で素材層を形成し焼成することができるものである。   The laying material 1 in which the core material is integrally wrapped with the porous material layer only by the air hole structure of the clinker ash without mixing the carbide (flammable substance) for forming the communication hole 2 in the material. Can be fired. Similarly, a bentonite as a linking material can be formed by forming a material layer by mixing only clay without mixing the bentonite and firing.
敷設材1は、嵩高い芯材の装填により素材全体が焼成過程での芯材による輻射熱作用と相俟って完全に連通する目詰まりのない多孔質構造を焼成させることができるため、大きな敷設材1の成形焼成が可能となり、且つ芯材4は敷設材1全体の嵩高に比例して大きくなり、安定感のある重量が得られるため、港湾などの波消しブロックのような大きな敷設材としても焼成することが可能となる。   The laying material 1 is capable of firing a porous structure without clogging, in which the entire material is completely connected to the radiant heat action of the core material during the firing process by loading a bulky core material, and is completely clogged. Since the material 1 can be formed and fired, and the core material 4 increases in proportion to the bulk of the laying material 1 and a stable weight can be obtained, it can be used as a large laying material such as a wave-blocking block in a harbor or the like. Can also be fired.
この実施例における原料の混合、この混合させた素材で芯材4を包み成形焼成する工程は、前記説明と略同じ要領で焼成し、芯材4として岩石、金属、鉄筋を入れた硬質コンクリートなどの不燃性物質を用い、ミキサーにて混合加水攪拌した素材を芯材4の表面に所定の肉厚で包着するよう型押しなどで成形して乾燥させ、また芯材4の形状によってはペースト状に湿式混合した素材を芯材4表面に幾層にも被着乾燥させて所定の肉厚にして焼成するもので、大きなものでは焼成過程において芯材4の輻射熱作用により素材の肉厚が25mmを多少超えるものでも、内部まで完全に均一な多孔質構造が得られるまでに焼成することができ、素材の肉厚は概ね25〜10mmを目安としている。   In the mixing of the raw materials in this embodiment, the step of wrapping and firing the core material 4 with the mixed material is performed in substantially the same manner as described above, and the core material 4 is made of rock, metal, hard concrete with reinforcing steel, or the like. Using a non-combustible substance, a material mixed and stirred with a mixer is molded by embossing or the like so as to cover the surface of the core material 4 with a predetermined thickness, and then dried. The material which has been wet-mixed in a shape is coated and dried on the surface of the core material 4 in a number of layers and fired to a predetermined thickness. In a large material, the thickness of the material is reduced by the radiant heat action of the core material 4 in the firing process. Even if the thickness slightly exceeds 25 mm, it can be fired until a completely uniform porous structure is obtained inside, and the thickness of the raw material is approximately 25 to 10 mm.
