本考案は、コンクリ−ト廃棄物を利用する人工漁礁に関するものである。 The present invention relates to an artificial fishing reef that uses concrete waste.
【０００２】[0002]
近年、産業廃棄物であるコンクリ−ト廃棄物が人工漁礁として再利用されてい る。すなわち、コンクリ−ト構造物の解体に際して発生する桁部や柱部等のコン クリ−ト廃棄物を所定寸法に切断し或いは端部のみ切断してできるコンクリ−ト 廃棄部材を近海、沿海、港湾或いは河川等の水域に沈下して漁礁とするものであ る。 しかしながら、これらのコンクリ−ト廃棄部材を利用する人工漁礁は、余りに も整い過ぎた単調、或いは規則的な形状とされており、またその一部である桁部 や柱部等も均整化或いは平滑化されているため、人工漁礁として利用されたとき 、貝類や海藻類等がその均整化或いは平滑化されたコンクリ−ト廃棄部材の表面 に棲息或いは付着し難く、従って、これら貝類や海藻類等を餌料とする魚類の集 魚効果に欠けるという問題点を有していた。 そこで、これらの問題点を解決するものとして、次のものが開示されている。 すなわち、特開平５−２３６８４４号公報には、多種・多彩な魚貝類や海藻類 、その他の水生産物にとって棲息しやすい人口漁礁の製造方法として、海底での 沈下使用中に腐蝕する長さ３cm以下の植物の茎稈を、魚貝類棲息用小穴の成形チ ップとし、前記チップの群数を漁礁となるコンクリ−ト塊の成形型枠内へ、その 生コンクリ−ト量の約３０％〜５０％だけ混入させて、前記コンクリ−ト塊を成 形固化し、その固化したコンクリ−ト塊の表面をアトランダムに欠き取ることに より、角張った天然の岩石風に異形粗面化する人口漁礁の製法が開示されている 。実開昭５８−１８５０６５号公報や特公昭５５−１０１５号公報には、誘魚 剤や肥料入り鉄パイプ製等の筒状容器をコンクリ−ト塊に埋設し、前記容器の一 端を前記コンクリ−ト塊の外部に露出させてなる誘魚剤入コンクリ−ト塊からな る漁礁用ブロックが開示されている。特開昭６３−１２５７１８号公報には、 コンクリ−ト塊から成る躯体下部と、柱材で囲まれた空間を有する躯体上部とが 、一体に構成された漁礁兼被覆・根固めブロックが開示されている。 In recent years, concrete waste, which is industrial waste, has been reused as artificial fishing reefs. That is, concrete waste materials such as girders and columns that are generated when the concrete structure is dismantled are cut to a specified size, or only the ends are cut off. Alternatively, it will sink into rivers and other water bodies to form fishing reefs. However, artificial reefs that use these concrete waste materials are too monolithic or have regular shapes, and the girders and columns that are part of them are also balanced or smooth. Therefore, when it is used as an artificial fishing reef, it is difficult for shellfish, seaweed, etc. to inhabit or adhere to the smoothed or smoothed surface of the concrete disposal member, and therefore these shellfish, seaweed, etc. There was a problem that the fish that feeds on fish lacked the effect of collecting fish. Therefore, the following is disclosed as a solution to these problems. That is, Japanese Patent Laid-Open No. 5-236844 discloses a method for producing artificial reefs that are easily habitat for various and various types of fish and shellfish, seaweeds, and other water products. The stem culms of the following plants are used as molding chips for small holes for fish and shellfish habitation, and the number of chips is put into the molding form of concrete blocks that form fishing reefs. By mixing up to 50%, the concrete lump is shaped and solidified, and the surface of the solidified concrete lump is cut out at random, so that it is deformed and roughened into a natural rock-like surface with a square shape. A method for making artificial reefs is disclosed. In Japanese Utility Model Publication No. 58-185065 and Japanese Patent Publication No. 55-1015, a tubular container made of iron pipe containing fish attractant or fertilizer is embedded in a concrete block, and one end of the container is made into the concrete container. -A fish reef block consisting of a concrete block containing a fish attractant exposed to the outside of the fish block is disclosed. Japanese Unexamined Patent Publication No. 63-125718 discloses a fishing reef / cover / consolidation block in which a lower part of a skeleton made of concrete mass and an upper part of a skeleton having a space surrounded by pillars are integrally formed. ing.

しかしながら上記従来の構成では、特開平５−２３６８４４号公報に記載の ものは、植物の茎稈のチップが嵩高で場所を取り、かつ比重差がありすぎ充填量 も多いことから生コンクリートと植物チップの混合に時間を要し生産性に欠ける とともに、該チップの混入時に風等で散らばり清掃等の後作業を要し作業性に欠 けるという問題点を有していた。実開昭５８−１８５０６５号公報や特公昭５ ５−１０１５号公報に記載のものは鉄パイプが腐食するとともに、誘魚剤の薬効 がきれると人工漁礁としての効果が小さいという問題点を有していた。特開昭 ６３−１２５７１８号公報に記載のものは、根固め用として使用することを目的 とし、人工漁礁を目的として使用するには重量がありすぎ、かつ躯体下部がコン クリート塊なので人工漁礁としての魚介類の棲息には不向であるという問題点を 有していることがわかった。 また、これらの人工漁礁や根固めブロックはいずれもバラス等の骨材を用いた 生コンクリートを用いコンクリート廃棄物やその破砕物を利用するものではなく 、重量が重く運搬性に欠けるという問題点を有していた。 また、コンクリ−ト廃棄物又はその破砕物は骨材として再利用するには経年に よるコンクリート劣化やひび割れによる強度不足の為利用することができず産業 廃棄物としてその処理方法が問題となっている。 However, in the above-mentioned conventional structure, the one described in Japanese Patent Laid-Open No. 5-236844 has a structure in which the stem culm chips of the plant are bulky and occupy a lot of space, and there is a large difference in specific gravity, and the filling amount is large, so that the concrete and plant chips However, there is a problem in that the mixing of the chips takes time and the productivity is insufficient, and that when the chips are mixed, the chips are scattered by wind or the like and post-work such as cleaning is required, and the workability is insufficient. The ones disclosed in Japanese Utility Model Publication No. 58-185065 and Japanese Patent Publication No. 5-1015 have the problem that the iron pipe is corroded and the effect as an artificial reef is small if the effect of the fish attractant is exhausted. Was there. The one described in JP-A-63-125718 is intended as an artificial fishing reef because it is intended to be used for root consolidation and is too heavy to be used as an artificial fishing reef and the lower part of the skeleton is a concrete lump. It was found that there is a problem that they are not suitable for the habitat of the seafood of. In addition, these artificial fishing reefs and root blocks do not use concrete waste or crushed concrete using raw concrete made of aggregate such as ballast, and have the problem of heavy weight and poor transportability. Had. In addition, concrete waste or crushed waste cannot be used for reuse as aggregate because of concrete deterioration over time and insufficient strength due to cracking, and its disposal method as industrial waste becomes a problem. There is.

この目的を達成するために本考案における請求項１記載の人工漁礁は、漁礁と なるコンクリ−ト躯体部の成形型枠内へ、骨材の群数及び隣接する骨材間の間隙 を充填し且つ接着凝固する接着剤を充填後固化してなる人工漁礁であって、前記 骨材がコンクリ−ト廃棄物及び／又はその破砕物からなり、その平均粒径が２〜 ２００mm、好ましくは４〜１００mm、更に好ましくは６〜７０mmであり、且つ前 記人工漁礁の表面に前記骨材が露出し凹凸部が形成され、及び前記接着剤が平均 粒径２〜４０mm、好ましくは５〜２０mmの粗骨材を有する生コンクリ−トである 構成を有している。 In order to achieve this object, the artificial fishing reef according to claim 1 of the present invention is such that the number of groups of aggregates and the gap between adjacent aggregates are filled in the molding frame of the concrete skeleton part which becomes the fishing reef. An artificial fishing reef that is solidified after being filled with an adhesive that adheres and solidifies, and the aggregate is made of concrete waste and / or its crushed material, and has an average particle diameter of 2 to 200 mm, preferably 4 to 100 mm, more preferably 6 to 70 mm, and the aggregate is exposed on the surface of the artificial fishing reef to form irregularities, and the adhesive has a mean particle size of 2 to 40 mm, preferably 5 to 20 mm. It has a structure that is a raw concrete with aggregate.
【０００６】 ここで、コンクリート廃棄物やその破砕物はその平均粒径が６mmより小さくな るにつれ人工漁礁の表面の凹凸部が小さくなり海草類が付着し難くなり２mm未満 では海草類が根を張ることができないため一部の海草しか付着せず漁礁適性に欠 けるので好ましくない。また、６〜７０mmでは人工漁礁の凹凸部が大きく海草が 根を張り易く、かつ小魚の棲息場としても好適であるが、７０mmより大きくなる につれコンクリート廃棄物の種類にもよるが嵩密度が高くなる傾向があり、海底 に沈着させた際波浪運動で移動し易くなり、かつ、生コンクリートの充填斑が生 じ耐久性に欠けるという欠点を有しているので好ましくない。 接着剤としての生コンクリート中の粗骨材は、平均粒径が２〜４０mm、好まし くは５〜２０mmのものが用いられる。５mmより小さくなるにつれコンクリート廃 棄物等の間に生コンクリートが密に充填されコンクリート廃棄物間の間隙をつぶ すとともに表面が均整化する傾向があり、２０mmより大きくなるにつれ生コンク リートの充填斑が生じ易く強度を弱める傾向があるのでいずれも好ましくない。 生コンクリートの充填量に対するコンクリートの廃棄物やその破砕物の充填量 は４０〜７０重量％、好ましくは４５〜６０重量％が望ましい。４５重量％より 少なくなるにつれ表面の粗面化が低下し、大きな孔隙が得られず、海草類の付着 性が低下する傾向があり、６０重量％より大きくなるにつれ強度が弱くなり設置 作業が困難になる傾向があるので好ましくない。 人工漁礁の製造方法は、型枠内にコンクリート廃棄物やその破砕物を充填し、 次いで所定の粒径の粗骨材を含有した生コンクリートを充填するとともに、コン クリート廃棄物や破砕機及び粗骨材の粒径が大きいときは、バイブレーターを用 いてもよい。但し、バイブレーターをかけすぎるとコンクリートの巣ができ易く なる傾向があるので注意を要する。生コンクリートが固化した後型枠を解体する ことにより人工漁礁を得ることができる。尚、型枠内に木片を固定したり、もし くは型枠板に穴をあけ挿脱自在に金属棒を配置することにより、魚介類の棲息に 好適な凹凸を容易に形成することができる。Here, as the average particle size of concrete waste and its crushed products becomes smaller than 6 mm, the irregularities on the surface of the artificial reef become smaller, and it becomes difficult for seagrass to adhere, and when it is less than 2 mm, seagrasses take root. This is not preferable because it cannot adhere to the seaweed and only a part of the seaweed adheres to it, making it unsuitable for fishing reefs. At 6 to 70 mm, the artificial fishing reef has large irregularities and seagrass easily roots and is suitable as a habitat for small fish. However, as it becomes larger than 70 mm, the bulk density increases depending on the type of concrete waste. It is not preferable because it has a tendency to move due to wave motion when it is deposited on the seabed, and it has poor durability due to uneven filling of fresh concrete. The coarse aggregate in the fresh concrete as the adhesive has an average particle size of 2 to 40 mm, preferably 5 to 20 mm. As the size becomes smaller than 5 mm, the raw concrete is densely packed between the concrete wastes and the gap between the concrete wastes is crushed and the surface tends to be well-balanced. Both are not preferable because they tend to occur and tend to weaken the strength. The filling amount of concrete waste or crushed product thereof with respect to the filling amount of green concrete is 40 to 70% by weight, preferably 45 to 60% by weight. When it is less than 45% by weight, the surface roughening decreases, large pores cannot be obtained, and the adhesion of seaweed tends to decrease. When it exceeds 60% by weight, the strength becomes weak and installation work becomes difficult. It tends to become unfavorable. Artificial fishing reefs are manufactured by filling concrete formwork with crushed concrete waste, then filling with concrete containing coarse aggregate of a specified particle size, and using concrete waste, crusher and crusher. A vibrator may be used when the particle size of the aggregate is large. However, care should be taken because concrete nests tend to form if the vibrator is applied too much. An artificial fishing reef can be obtained by dismantling the formwork after the raw concrete has solidified. In addition, by fixing a piece of wood in the formwork or by arranging a metal rod that can be inserted and removed by making a hole in the formwork plate, it is possible to easily form irregularities suitable for the habitation of seafood. .

この構成によって、コンクリート廃棄物や破砕物間に所定の粒径の粗骨材を含 有した生コンクリートが程よく充填されて接合されているのでコンクリートの劣 化やひび割れを防止し耐久性に優れた漁礁とすることができる。表面にコンクリ ート廃棄物やその破砕物が露出し凹凸状となっているので海草や貝類を容易に付 着させることができ、魚の棲息を促すことができる。 産業廃棄物としてその処分場の獲得が困難であったコンクリート廃棄物を漁礁 に加工することによりコンクリート廃棄物を有効に利用することができる。 With this structure, fresh concrete containing coarse aggregate with a specified particle size is properly filled and joined between concrete waste and crushed material, preventing deterioration and cracking of the concrete and excellent durability. It can be a reef. Since concrete waste and its crushed material are exposed and uneven on the surface, seaweeds and shellfish can be easily attached to them, and fish can be inhabited. Concrete waste can be effectively used by converting it into fishing reef, which was difficult to obtain as a disposal site as industrial waste.

以下本考案の一実施例について、図面を参照しながら説明する。 図１（ａ）は本実施例における人工漁礁のコンクリ−ト躯体部を示す全体斜視 図、図１（ｂ）は前記図１（ａ）におけるＡ部の拡大図である。 １はコンクリートの廃棄物やその破砕物と生コンクリートで左右側面及び上面 中央部に貫設された開口部を有する本実施例の人工漁礁、２は波に揺動されない 重量が付与された人工漁礁１のコンクリート躯体部、３は人工漁礁１の側面中央 部に貫設され海水の流れを通し海水を更新するための開口部、４は平均粒径が２ 〜２００mmのコンクリートの廃棄物やその破砕物、５はコンクリート躯体部のマ トリックスを形成する生コンクリート、５′は生コンクリート中に含有されてい る平均粒径が２〜４０mmの砂利等からなる粗骨材である。 前記図１（ａ）に示すように、本実施例の人工漁礁はそのコンクリ−ト躯体部 ２を略立方体状として形成されている。またコンクリ−ト躯体部２の側面略中央 部より対向する側面に亘って略矩形状を呈する開口部３が形成されている。これ により、各開口部３が交差して形成されているので、コンクリ−ト躯体部２の略 中央部には魚貝類や海藻類等の水生産物の棲息空間が形成されることになる。 また、前記図１（ｂ）に示すように、コンクリ−ト躯体部２表面には後述する コンクリ−ト廃棄物及び／又はその破砕物４が露出し、その結果、該コンクリ− ト躯体部２は凹凸状を呈して形成されている。更に、コンクリ−ト破砕物等４が 平均粒径２〜２００mm、或いは４〜１００mm、或いは６〜７０mmと大幅な範囲を 持って形成されたことにより、より自然な表面形状とされている。このように、 コンクリ−ト躯体部２の表面が、凹凸状を呈し一見角張った天然の岩石風に粗面 化されることにより、その人工漁礁の表面には海藻類が繁殖し易くなり、この結 果、魚貝類等の水生産物の誘致効果に優れることになる。また、前述したように コンクリ−ト躯体部２の表面が粗面化されることにより、その粗面部のアンカ− 効果により近海、沿海、港湾或いは河川等の水域に段積して設置しても、安定し て設定できる。また海底等に沈下させてもその粗面部により海底の岩等に掛止さ れ風雨波浪等の天候条件となっても漁礁の移動等を防ぐことができる。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 (a) is an overall perspective view showing the concrete skeleton part of the artificial fishing reef in this embodiment, and FIG. 1 (b) is an enlarged view of part A in FIG. 1 (a). 1 is a waste of concrete or its crushed material and fresh concrete is an artificial fishing reef of the present embodiment having an opening penetrating in the left and right side surfaces and the central part of the upper surface, 2 is an artificial fishing reef to which weight is not shaken 1 is a concrete skeleton part, 3 is an opening penetrating the center part of the side surface of the artificial fishing reef 1 to allow the flow of seawater to replenish the seawater, and 4 is waste of concrete with an average particle size of 2 to 200 mm and its crushing. Reference numeral 5 is green concrete forming the matrix of the concrete skeleton, and 5'is coarse aggregate made of gravel or the like having an average particle size of 2 to 40 mm contained in green concrete. As shown in FIG. 1 (a), the artificial fishing reef of this embodiment has a concrete skeleton 2 having a substantially cubic shape. Further, an opening 3 having a substantially rectangular shape is formed from the substantially central portion of the side surface of the concrete skeleton portion 2 to the opposite side surface. As a result, since the openings 3 are formed so as to intersect with each other, a habitat for water products such as fish and shellfish and seaweeds is formed in the approximate center of the concrete skeleton 2. Further, as shown in FIG. 1 (b), concrete waste and / or crushed material 4 which will be described later are exposed on the surface of the concrete skeleton portion 2, and as a result, the concrete skeleton portion 2 is exposed. Is formed to have an uneven shape. Further, the concrete crushed material 4 is formed in a large range with an average particle diameter of 2 to 200 mm, or 4 to 100 mm, or 6 to 70 mm, so that it has a more natural surface shape. In this way, the surface of the concrete skeleton 2 is roughened by a natural rock-like appearance that is uneven and looks angular, so that seaweeds easily propagate on the surface of the artificial fishing reef. As a result, it will be excellent in attracting water products such as fish and shellfish. Further, as described above, the surface of the concrete skeleton part 2 is roughened, so that the anchor effect of the roughened surface part makes it possible to stack and install it in waters such as near sea, coastal areas, harbors or rivers. , Can be set stably. In addition, even if it is submerged on the sea floor, it can be prevented from moving due to being caught on rocks on the sea floor due to its rough surface, even under weather conditions such as wind and rain waves.

FIG. 2 is a cross-sectional view showing a state in which the number of aggregate groups and mortar are filled in the molding form of the concrete body portion of the artificial fishing reef of the present embodiment, that is, the curing period of the so-called concrete body portion. In FIG. 2, 2 is a concrete skeleton part which becomes an artificial reef, 3 is an opening part, 4 is concrete waste or its crushed material, 5 is fresh concrete containing coarse aggregate, and FIG. Since they are similar, the same reference numerals are given and the description thereof is omitted. 6 is a formwork for molding artificial fishing reefs. First, concrete waste is crushed or crushed by a crushing machine or a crushing machine so that the average particle size becomes 2 to 200 mm. After crushing or crushing the concrete waste, the concrete waste having an average particle diameter of 2 to 200 mm or the crushed product may be selected by a sieving machine or the like. When the crushed concrete waste has an average particle size of 2 to 200 mm, and more preferably an average particle size of 6 to 70 mm, a uniform concrete skeleton 2 having excellent strength and the like, and a suitable fishing reef The concrete skeleton part 2 can be created. Next, the molding frame 6 is filled with the crushed material 4 of the concrete waste having the above-mentioned average particle diameter of 2 to 200 mm. At this time, as described above, since the crushed product 4 of the concrete waste has an average particle size of 2 to 200 mm (preferably an average particle size of 4 to 100 mm, more preferably an average particle size of 6 to 70 mm). ), Naturally, that is, in the crushed waste 4 of the concrete waste, those having a smaller average particle size fill the gaps between those having a larger average particle size in the molding frame 6 at random. Will be compounded / loaded. Here, if the crushed waste 4 of concrete waste is filled with 40% to 70% of the volume of the molding frame 6, sufficient weight and strength as a fishing reef will be secured as described above. Stable stacking is possible and movement of fishing reefs can be prevented even under weather conditions such as wind and rain waves, and since the porosity is relatively high, the weight can be reduced and the transportability of the concrete body part 2 is improved. be able to. Further, if necessary, an appropriate amount of crushed stone or the like generally used as an aggregate may be mixed in order to secure the strength and weight of the concrete skeleton portion 2 which becomes a reef. Next, the concrete frame 6 is filled with fresh concrete 5 using a concrete pump, and the top end is leveled with a trowel or the like. After this, the concrete skeleton 2 is formed with a curing period of about 4 to 5 days. After this curing period, the molding mold 6 is removed to complete the artificial fishing reef 1 of this embodiment. As described above, according to the present embodiment, the number of groups of the crushed waste 4 of concrete waste as aggregate and the adjacent concrete are placed in the forming mold 6 of the concrete skeleton 2 which becomes a fishing reef. By filling the gaps between the sewage waste and the crushed waste 4 and the raw concrete 5 that adheres and solidifies, it is possible to form the concrete skeleton 2 as a fishing reef having sufficient strength and weight, and By exposing the crushed waste 4 of concrete waste on the surface, it is possible to inexpensively form the artificial fishing reef 1 as a suitable habitat for water products such as fish and shellfish and seaweed. It has been found that it is also possible to form a concavo-convex portion of any size by fixing a piece of wood to the molding frame 6 or by detachably inserting a metal rod having a predetermined diameter. In addition, the artificial fishing reef of the present invention is not limited to the above-mentioned embodiment, and for example, the crushed concrete waste is formed on the surface of the concrete skeleton part having a substantially hollow cylindrical shape or a substantially triangular pyramid shape. It may be formed by exposing an object. Of course, a plurality of openings suitable for water products such as fish and shellfish and seaweeds are formed in these concrete skeletons. Further, for example, the concrete skeleton part having a substantially trapezoidal cross section, that is, the area of the lower wall surface is larger than that of the upper wall surface, and the left and right wall surfaces and the front and rear wall surfaces are not inclined with a predetermined angle with respect to the lower wall surface. It may also be formed by exposing the crushed product of the concrete waste on the surface of the concrete skeleton part formed by the above. It goes without saying that the effects similar to those of the above-described embodiment can be obtained in these other embodiments as well.
