Description

本発明は、防草シートの設置方法と、その防草シートに関する。 The present invention relates to a method for installing a weed-proof sheet and the weed-proof sheet.

この種の道路のコンクリートと、ブロックとの目地とか、その他の目地に形成した防草用の倒Ｖ字形の切込み溝に、倒Ｖ字形の防草シートを布設する防草シートの設置方法として、本出願人の一人が提出する特許第４８７４９２７号の特許発明がある。この発明の概要は、コンクリートカッターで境界目地の表面を頂点に下向き第一傾斜切込みライン、及び下向き第二傾斜切込みラインを切削し、略倒Ｖ字形の下向き切込み山形溝を形成し、下向き切込み山形溝に相似形の略山形形状の防草板を挿入し、下向き切込み山形溝と略山形形状の防草板との隙間（Ｈ１）には、接着剤等の充填剤を注入する工法である。防草板の材質は、耐腐食性と耐久性を有し、害のない材質である。しかし、下向き切込み山形溝と略山形形状の防草板との隙間（Ｈ１）に、充填剤を注入する空気溜りがあって、ひび割れが発生する場合があった。 As a method of installing a weed-proof sheet in which an inverted V-shaped weed-proof sheet is laid in an inverted V-shaped notch groove for weed-proof formed at joints between concrete and blocks of this type of road, or other joints. There is a patented invention of Patent No. 4874927 submitted by one of the applicants. The outline of the present invention is to cut a downward first inclined notch line and a downward second inclined notch line with a concrete cutter at the apex of the surface of the boundary joint to form a substantially inverted V-shaped downward notch chevron groove, and a downward notch chevron. This is a construction method in which a substantially chevron-shaped weed-proof plate having a similar shape is inserted into the groove, and a filler such as an adhesive is injected into the gap (H1) between the downwardly cut chevron-shaped groove and the substantially chevron-shaped weed-proof plate. The material of the weed-proof plate is a harmless material having corrosion resistance and durability. However, in the gap (H1) between the downward notch chevron groove and the substantially chevron-shaped weed control plate, there was an air pool into which the filler was injected, and cracks sometimes occurred.

そこで、充填剤を無くし、かつ空気が入らない目地の防草シート構造を提案する。即ち、目地の隙間から雑草が成長することを防止できる合成樹脂製の防草シート、防草板等に関する先行文献を下記に示す。 Therefore, we propose a weed-proof sheet structure for joints that eliminates the filler and does not allow air to enter. That is, the prior literature relating to a synthetic resin weed-proof sheet, a weed-proof board, etc. that can prevent weeds from growing from the gaps in the joints is shown below.

文献（１）は、特開２０１６－１０８７４８号公報（防草具及びそれを用いた防草構造）であって、新設・改修工事の時に利用する合成樹脂やゴムでなる遮蔽部において、空気溜りを防ぐ膨出構造が開示されている（図３参照）。しかしながら、本発明が意図する「防草用の倒Ｖ字形の切込み溝に、倒Ｖ字形の防草シートを布設する」構造ではない。 Document (1) is Japanese Patent Application Laid-Open No. 2016-108748 (weed-proofing tool and weed-proof structure using the same), and is an air pool in a shielding portion made of synthetic resin or rubber used at the time of new construction / repair work. A bulging structure that prevents this is disclosed (see FIG. 3). However, it is not the structure intended by the present invention to "lay an inverted V-shaped weed-proof sheet in the inverted V-shaped notch groove for weed-proofing".

また、文献（２）は、特開２０１４－０９８２３１号公報（コンクリート構造物の目地防草構造）であって、防草板の緩衝材本体の壁面から外側に突出した防草板であって、この防草板は、傾斜角を７０°の下向きに傾斜されており、かつ施工時において、防草板は、走行方向において、水平面に対する傾斜角を３°以内とした状態で布設する構造である。従って、前述した、本発明の構造は備えていない。 Further, Document (2) is Japanese Patent Application Laid-Open No. 2014-098231 (joint weed-proof structure of concrete structure), which is a weed-proof plate protruding outward from the wall surface of the cushioning material main body of the weed-proof plate. This weed-proof plate is inclined downward by 70 °, and at the time of construction, the weed-proof plate is laid in a state where the inclination angle with respect to the horizontal plane is within 3 ° in the traveling direction. .. Therefore, it does not have the structure of the present invention described above.

上記に鑑み、本発明では、空気溜りの隙間（Ｈ１）を無くすことと、接着剤等の充填剤を注入しない構造の防草シートの設置方法と、その構造を提供する。即ち、埋め戻し時において、補修材を確実に充填することと、転圧作業で、防草用の倒Ｖ字形の切込み溝に、倒Ｖ字形の防草シートを、隙間なく埋設する（付設する）ことを特徴とする。 In view of the above, the present invention provides a method for eliminating a gap (H1) in an air reservoir, a method for installing a weed-proof sheet having a structure that does not inject a filler such as an adhesive, and a structure thereof. That is, at the time of backfilling, the repair material is surely filled, and the inverted V-shaped weed-proof sheet is buried (attached) in the inverted V-shaped notch groove for weed-proofing by rolling compaction work. ).

An example of forming a W-shaped notch groove 12 is shown in FIG. 4-2, in which a weed-proof sheet 1 is wrapped around a mountain-shaped portion of the W-shaped downward notch groove 12 in the longitudinal direction X, and a repair material 14 is formed. Shows the state before filling.

続いて、図４－２の好ましい施工例を、図５の別の第１例～図１０の別の第６例（第１例～第６例）を用いて、順次、説明する。 Subsequently, a preferred construction example of FIG. 4-2 will be sequentially described with reference to another first example of FIG. 5 to another sixth example of FIG. 10 (first to sixth examples).

図５の一例では、道路Ｒのコンクリート１０と、ブロック１１との目地Ｒ１に、一枚刃物のコンクリートカッター工法（図示せず。以下同じ。以下、「一枚刃物カッター工法」という）で、倒Ｖ字形にカットする（切込む）ことで、単列方式（限定されない。以下、同じ）の倒Ｖ字形（山形形状）の切込み溝１２を形成する。即ち、コンクリート１０の表面（図示せず）か、コンクリート１０の表面とブロック１１の表面との目地Ｒ１に、下向き第１傾斜切込みライン１２００、及び下向き第２傾斜切込みライン１２０１を形成して、カットした箇所のコンクリート１０と、ブロック１１等をはつり（以下省略）、倒Ｖ字形の切込み溝１２（切込み山形溝）を形成する。この切込み溝１２に、防草シート１を包被し、その後、補修材１４を充填し、施工完了した状態の一例の拡大断面図を示しており、前述の図４－２に準ずる。尚、切込み溝１２は、コンクリート１０等の表面からの深さは、原則として、自由である（他の各例も同じ）。そして、図３－２等のように、舗装面Ａと、山形１６００の頂面との間には、段差Ｂが形成される。この段差Ｂと切込み溝１２との空間に、舗装材１４を充填し、かつ舗装材１４等を転圧する。 In an example of FIG. 5, the concrete 10 of the road R and the joint R1 of the block 11 are knocked down by a single-blade concrete cutter method (not shown. The same shall apply hereinafter; hereinafter referred to as "single-blade cutter method"). By cutting (cutting) into a V-shape, a single-row (not limited, the same applies hereinafter) inverted V-shaped (crate-shaped) cut groove 12 is formed. That is, a downward first inclined notch line 1200 and a downward second inclined notch line 1201 are formed at the joint R1 between the surface of the concrete 10 (not shown) or the surface of the concrete 10 and the surface of the block 11 to cut. The concrete 10 and the block 11 and the like are suspended (hereinafter omitted) to form an inverted V-shaped notch groove 12 (notch chevron groove). An enlarged cross-sectional view of an example in which the cut groove 12 is covered with the weed-proof sheet 1 and then the repair material 14 is filled and the construction is completed is based on FIG. 4-2 described above. In principle, the depth of the cut groove 12 from the surface of the concrete 10 or the like is free (the same applies to each of the other examples).
