Description

本発明は、歩道などにおける植え込み、公園や学校などにおけるグラウンド、未舗装道路、その他の特定地において、雑草の発生を抑制するために行う抑草地盤の施工方法に関するものである。   The present invention relates to a method of constructing a suppression ground that is performed in order to suppress the generation of weeds in planting on a sidewalk or the like, on a ground in a park or school, an unpaved road, or other specific sites.

従来、雑草の発生を抑制するための施工は、施工現場に抑草性組成物を主材とする抑草材を必要量搬入して、該抑草材を特定地に敷設して抑草地盤を構築するのが通例である。   Conventionally, construction to suppress the generation of weeds has been carried out by bringing a necessary amount of a herbicidal material mainly composed of a herbicidal composition into the construction site, and laying the weeding material on a specific ground. It is customary to construct

その際、所要の抑草材は、例えば10〜20kgなどの所定量毎に適宜な包装袋に袋詰め包装された状態で施工現場に搬入されるものであることから、施工現場において抑草材を包装袋から取り出した後には、使用後の包装袋がゴミとなって多量に残存することとなる。それがために、施工現場においては抑草材を取り出した後に残存する使用済みの包装袋を回収し、その後廃棄処理するなどの後始末が不可避的に現場作業として付随することとなり、施工上煩わしく作業能率の向上を妨げる一因となっているという問題があった。

After the bag is taken out from the packaging bag, the used packaging bag becomes garbage and remains in a large amount. For this reason, at the construction site, the used packaging bags that remain after taking out the herbicide material are collected and then disposed of after disposal, which is unavoidably accompanied by site work. There was a problem that it was one factor that hindered the improvement of work efficiency.
JP-A-8-291014

本発明は、如上の問題を解消すべく案出したものであって、抑草地盤の施工現場において、搬入された抑草材が、包装袋から取り出された後に残存する使用済みの包装袋をゴミ化させることなく、これを抑草資材として施工現場で有効活用でき得るようになし、施工現場において発生する抑草材を取り出した後に残存する使用済みの包装袋の回収及び廃棄処理などの後始末の現場作業を消滅させて施工上の作業能率を向上させることのできる有益な抑草地盤の施工方法を提供することを目的とするものである。   The present invention has been devised to solve the above-mentioned problems. In the construction site of the suppression grass ground, the used packaging bag that remains after the imported suppression material is removed from the packaging bag is provided. After making it possible to effectively use it as a suppression material at the construction site without making it garbage, after collecting the used packaging bag remaining after taking out the suppression material generated at the construction site and disposing of it The purpose of the present invention is to provide a method for constructing a beneficial weeding ground that can eliminate work at the end of the process and improve work efficiency in construction.

本発明に係る抑草地盤の施工方法は、浄水処理ケーキを粉砕してなる粉粒状浄水処理ケーキに土壌固化材、天然有機素材を混合するなどの抑草性組成材からなる抑草材を、生分解性プラスチックなどの自然分解性材料を素材として製造された包装袋をもって袋詰め包装し、抑草地盤の施工現場において、搬入して包装袋から抑草材を取り出した後に残存する当該使用済みの包装袋を抑草地盤の最下層に並列状に敷設し、しかる後に前記包装袋から取り出してなる抑草材を積層状に敷設して舗装することを最も主要な特徴とするものである。   The method for constructing a suppression grass ground according to the present invention comprises a suppression material made of a suppression material such as a soil-solidifying material and a natural organic material mixed in a granular purified water treatment cake obtained by crushing a purified water treatment cake, Used and packaged in packaging bags made of natural degradable materials such as biodegradable plastics, and used after being taken in and taken out of the packaging bags at the construction site of the suppression grass. The main feature is that the packaging bags are laid in parallel in the lowermost layer of the weeding ground, and then the weeding material taken out from the packaging bags is laid in a laminated form and paved.

本発明に係る抑草地盤の施工方法によれば、抑草材を包装する包装袋を自然分解性材料をもって製造することにより、抑草地盤の施工現場において、搬入した包装袋に包装されてなる抑草材の当該抑草材を取り出した後の使用済みの包装袋を抑草地盤の最下層の抑草資材として自然環境を阻害するおそれなく有効活用することができることから、使用済みの包装袋のごみ化を消滅させて施工能率を向上することができ、また、所定期間内、宿根性雑草に対する出芽抑制の抑草効果を強化することができる一石二鳥の優れた効果を奏する。   According to the construction method of the grass suppression ground according to the present invention, the packaging bag for packaging the grass suppression material is manufactured with a natural degradable material, and is packed in the packaging bag carried in at the construction site of the grass suppression ground. Since the used packaging bag after taking out the said herbicide material can be effectively used as the bottom layer of the weeding material without the risk of disturbing the natural environment, the used packaging bag The efficiency of construction can be improved by eliminating the waste, and the excellent effect of two birds with one stone that can enhance the suppression effect of budding suppression against perennial weeds within a predetermined period.

以下に、本発明を実施例に基づいて説明する。   Hereinafter, the present invention will be described based on examples.

本発明方法の実施に使用する抑草材を袋詰め包装する包装袋は、生分解性プラスチックなどの自然分解性材料を素材として製造されるものである。生分解性プラスチックなどの自然分解性材料は、自然界においてそのまま土壌中の微生物の作用によって分解され、肥料養分として土に還える特性を有するものである。その基本構成は、例えば、澱粉粉末、エチレン酢酸ビニル共重合体、増強ポリエチレン樹脂、天然油脂などからなる生分解性合成樹脂組成物である。澱粉粉末としては、一般にとうもろこし澱粉、小麦澱粉、米澱粉、じゃがいも澱粉、甘藷澱粉、タビオカ澱粉などの穀物類、野菜類から得られる各種の天然澱粉が挙げられる。本発明の実施にあっては、土壌中において微生物による分解に1〜2年の期間を要する分解速度の遅い自然分解性材料を用いることが好ましい。   A packaging bag for packing and packing a herbicidal material used for carrying out the method of the present invention is manufactured from a natural degradable material such as a biodegradable plastic. Naturally degradable materials such as biodegradable plastics have the property of being decomposed by the action of microorganisms in the soil as they are in nature and returning to the soil as fertilizer nutrients. The basic composition is, for example, a biodegradable synthetic resin composition made of starch powder, ethylene vinyl acetate copolymer, reinforced polyethylene resin, natural fats and oils, and the like. Examples of starch powders include corn starch, wheat starch, rice starch, potato starch, sweet potato starch, tabioca starch, and various natural starches obtained from vegetables. In practicing the present invention, it is preferable to use a naturally degradable material having a slow degradation rate that requires a period of 1 to 2 years for decomposition by microorganisms in the soil.

また、本発明方法の実施に使用する抑草材は、その種類、成分を限定するものではないが、例えば、浄水処理ケーキを粉砕して篩い分けし、それを加熱、乾燥した強い撥水性を有する粉粒状浄水処理ケーキを主原料にして、それに土壌固化材及び植物生長抑制作用(アレロパシー活性)を持つ天然有機素材を混合するなどして得られた抑草性組成材からなるものが優れた抑草効果を有し好適である。   In addition, the type and ingredients of the herbicide used in the implementation of the method of the present invention are not limited. For example, the water-treated cake is crushed and sieved, and heated and dried to provide strong water repellency. What consists of a herbicidal composition obtained by mixing a powdered water-purified cake with a soil solidifying material and a natural organic material having a plant growth inhibitory action (allelopathic activity), etc. It has a herbicidal effect and is suitable.

浄水処理ケーキは、浄水場において浄水を製造する際に、汚濁物質として浄水から分離されるものであり、該浄水処理ケーキを粒径10mm以下に粉砕し、篩い分けして粒径粒径4.5mm以上10mm以下の粗粒物と粒径4.5mm未満の粉末物とを混合したものが、粉粒状浄水処理ケーキである。本来、廃棄物である浄水処理ケーキの有効利用である。   The purified water cake is separated from purified water as a pollutant when producing purified water at a water purification plant, and the purified water treated cake is crushed to a particle size of 10 mm or less and sieved to obtain a particle size of 4. A mixture of a coarse product having a particle size of 5 mm or more and 10 mm or less and a powder product having a particle size of less than 4.5 mm is a granular water purification treated cake. Originally, it is an effective use of water-purified cakes that are waste.

土壌固化材は、セメント系土壌固化材、石灰系土壌固化材、マグネシウム系土壌固化材、石膏系土壌固化材の一種または二種以上の混合物からなるものである。   The soil-solidifying material is composed of one or a mixture of two or more of cement-based soil-solidifying material, lime-based soil-solidifying material, magnesium-based soil-solidifying material, and gypsum-based soil-solidifying material.

植物生長抑制作用(アレロパシー活性)を持つ天然有機素材は、例えば、コーヒー粕、モミガラ、針葉樹のオガクズなどが挙げられる。   Examples of natural organic materials having a plant growth-inhibiting action (allelopathic activity) include coffee candy, rice straw, coniferous sawdust, and the like.

上記のような抑草性組成材からなる抑草材は、透水性を有すると共にシリカ、酸化アルミニウム、マグネシウムを多量に含有することから、土粒子間の水分枯渇化とリン酸吸収能によるリン酸欠乏土壌を形成することができ、これにより、飛散種子に対して発芽を抑制することができると共に宿根性雑草に対して固化力により物理的に出芽を抑制することができる。   The herbicidal material composed of the herbicidal composition as described above has water permeability and contains a large amount of silica, aluminum oxide, and magnesium. A deficient soil can be formed, and thereby germination can be suppressed with respect to scattered seeds, and germination can be physically suppressed with respect to perennial weeds by solidification power.

そして、上記のように構成された抑草材は、前記した自然分解性材料を素材として製造された生分解性プラスチック製の包装袋を用いてこれに袋詰め包装される。   The herbicidal material configured as described above is packaged and packaged in a biodegradable plastic packaging bag manufactured using the natural degradable material described above.

次に、上記に例示してなる抑草資材を用いて本発明に係る抑草地盤の施工方法を説明する。   Next, the construction method of the weeding ground which concerns on this invention using the weeding material illustrated above is demonstrated.

雑草の発生を抑制したい場所を抑草地盤とするため、その施工現場において、搬入した抑草材を該抑草材を袋詰め包装してなる包装袋から取り出し、しかる後に、抑草材を取り出した後に残存する使用済みの包装袋を、裸地或いは前もって自生雑草を刈り取るなどして取り除いた土壌表面に並列状に敷設して、該使用済みの包装袋をもって抑草地盤の最下層を形成する。   In order to make the place where weed generation should be suppressed to the suppression ground, take out the imported suppression material from the packaging bag formed by packing the suppression material, and then remove the suppression material. The used packaging bags that remain after the laying are laid in parallel on the bare soil or the soil surface that has been removed by cutting away native weeds in advance, and the used packaging bags form the bottom layer of the suppression ground. .

ここにおいて、当該土壌表面は、必要に応じて掘り下げ窪地となした上で施工を行うことも可能である。このような施工を実施すると、抑草地盤の表面をその周囲の土壌表面と均等に設定することができる。   Here, the soil surface can be constructed after being dug down as necessary. If such construction is carried out, the surface of the suppression grass ground can be set evenly with the surrounding soil surface.

また、使用済みの包装袋を土壌表面に敷設するに先立って前もって多数の針穴を設けるように加工し、透水性を付与するように構成することも必要に応じて適宜に実施することができる。   In addition, prior to laying a used packaging bag on the soil surface, it can be processed to provide a large number of needle holes in advance and configured to impart water permeability as needed. .

その後に、前記したような抑草材を水と混練りした上で、該抑草材を上記の並列状に敷設してなる包装袋上に、例えば2〜6cmの適宜厚みを持って積層状に敷設し、そしてこれを鎮圧、固化させて抑草地盤を構築し舗装する。   Then, after kneading the above-mentioned herbicide material with water, it is laminated on the packaging bag formed by laying the herbicide material in the above-mentioned parallel shape with an appropriate thickness of, for example, 2 to 6 cm. And then squeeze and solidify it to build and pave the grass.

このような施工方法によって得られる抑草地盤は、その地盤表面からの雑草の発生及び飛来種子からの雑草の発生、定着を抑制することができる。のみならず、抑草地盤の最下層に敷設した自然分解性材料からなる包装袋が自然分解する迄の期間に亘って、宿根性雑草や雑草地下茎、更には埋没種子などから出芽する雑草の発生の抑制を強化することができ、優れた雑草の発生抑制効果を奏することができる。   The suppression ground obtained by such a construction method can suppress the generation of weeds from the ground surface and the generation and establishment of weeds from flying seeds. Not only that, but the generation of weeds that emerge from perennial weeds, weeds, and even embedded seeds over the period of time until the packaging bags made of naturally-degradable materials laid on the bottom layer of the suppression grass naturally decompose. Can be strengthened, and an excellent effect of suppressing the generation of weeds can be achieved.

また、抑草地盤の施工に際して、抑草材を袋詰め包装してなる包装袋を、施工現場において抑草材を取り出した後に残存する使用済みとなった当該包装袋を抑草資材として有効活用してゴミ化することを消滅し得て、後始末を無くして施工能率を向上でき、きわめて有益な優れた抑草地盤の施工方法である。



In addition, when constructing the suppression ground, the packaging bag formed by packing the suppression material into a bag is effectively used as the suppression material after the removal of the suppression material at the construction site. It is a very useful method of constructing a well-suppressed ground, which can eliminate the waste and eliminate the cleanup and improve the construction efficiency.
