Description
本考案は、盛土・切土が形成された造成裸地法面において、路面部や法肩部から流れ込む雨水等による浸食・崩壊を防止する雨裂防止マット体に関するものである。 The present invention relates to a rain-crack-preventing mat body that prevents erosion / collapse by rainwater flowing from a road surface portion or a shoulder portion on a bare bare slope with embankments and cuts.
新設道路や団地造成等により、造成された盛土・切土の裸地法面は、緑化等で法面が保護されるまでに、法肩より雨水や融雪水が法面に流れ込むことによって法面が浸食され、法面崩壊の危険や景観の悪化をまねくといった事態が起きている。そこで、法肩部から法面に流れ込む水を防止するために、植生土のう袋や枕土のう袋等の土のう袋に土を詰め込み、法肩部に並べて法面に流れ込む水を堰き止める方法や実登文献１に記載のマット体を丸めて丸太状にしたものを敷設する工法が考えられる。
The bare slopes of embankments and cuts created by new roads, housing estates, etc. are sloped by rainwater and snowmelt flowing into the slopes before they are protected by greening. Has been eroded, leading to the risk of slope collapse and the deterioration of the landscape. Therefore, in order to prevent water from flowing into the slope from the shoulder, soil is stuffed into a soil bag, such as a vegetation bag or a pillow bag, and the water flowing into the slope along the shoulder is dammed. A method of laying a rounded mat body described in Document 1 is conceivable.
しかし、植生土のう袋や枕土のう袋等を用いて、法肩よりに流れ込む雨水等の水を堰き止めるには、現場で土のう袋に土を詰め込み、１袋当たり十数ｋｇの重さとなる土のう袋を法肩まで荷揚げ設置することは重労働であるとともに斜面での荷揚げ作業は、事故の発生するおそれがある。また、特許文献１の方法も、土を詰めた重い土のう袋のかわりとして軽いマット体を丸太状にして設置するものだが、これらの方法だと路肩から流れてくる雨水等を法肩部で塞き止める事はできるが、最も浸食や崩壊が多い法肩から法面の上部の保護ができないのである。 However, using a vegetation bag or a pillow bag, etc., to dam the rainwater that flows from the shoulder, the soil bag is filled with soil at the site and the weight of the bag is over 10 kg. It is hard work to unload to the shoulder and unloading work on the slope may cause an accident. In the method of Patent Document 1, a light mat body is installed in a log shape instead of a heavy sandbag filled with soil. With these methods, rainwater flowing from the road shoulder is blocked by the shoulder. You can stop, but you can't protect the top of the slope from the shoulder with the most erosion and collapse.
本考案は、上記の問題を解決すべく盛土・切土の裸地法面の法肩より流れ込む水による法面の浸食・崩壊を手軽に安価な費用で防止することが可能な雨裂防止マット体の提供。 The present invention is a rain-crack prevention mat that can easily prevent erosion and collapse of slopes due to water flowing in from the shoulders of bare ground slopes of embankments and cuts in order to solve the above problems at a low cost. Body offer.

Artificial soil with seeds and fertilizer added is laid down and compressed several centimeters thick, and the upper part is formed by overlapping polyester nonwoven fabric and polyethylene plain weave sheet in that order, and the bottom and upper part are integrated to suppress the movement of artificial soil in the body. A mat body is formed by sewing at predetermined intervals so as to firmly hold the structure. The artificial soil at this time is light and has high water retention when dried.
次に、と竹の葉を破砕したものと安定剤を混ぜ表面に吹き付けたポリエチレン性の遮光率６５％の遮光ネットの下部に、水溶性の紙シートに所望植物の短草種子と化成肥料と遅効性肥料が付着した種子シートを貼りつけたものを十数メートルのロール状にし（以下、雨裂防止シート）、その一辺を上記のマットに熱接着にて接着して雨裂防止マット体とするものである。 Next, underneath the polyethylene shading net with 65% shading of the bamboo mixed with the crushed bamboo leaf and stabilizer, sprayed on the water-soluble paper sheet with short grass seeds and chemical fertilizer of the desired plant Put a seed sheet with a slow-acting fertilizer on it into a roll of dozens of meters (hereinafter referred to as a rain crack prevention sheet), and bond one side of the mat to the above mat by thermal bonding. To do.
人工土壌を内包した雨裂防止マット体は、破損しにくく耐候性に優れたシートで形成しているので腐食しにくく長期間原形を保ち、路面部から法面部にかけて敷設することで流れ込む水・泥や雨等による路面部、法肩部、法面上部の浸食・崩壊を長期間防除する。そして、マット体に取り付けた雨裂防止シートを広げ固定することで法面中部から下部の雨裂防止効果を発揮する。また、従来の土を詰め込んだ土のう袋より、重さが数Ｋｇと軽量なので法肩等への運搬や設置が容易に行え、法肩より法面に流れ込む降雨や融雪水等の水や泥の流出を防止するとともに裸地法面全体の浸食防止とマット体に内包された種子と種子シートによる緑化が手軽に安価な価格でできる。 The rain-crack-preventing mat body that contains artificial soil is made of a sheet that is not easily damaged and has excellent weather resistance, so it does not corrode easily and maintains its original shape for a long period of time. Prevent long-term erosion and collapse of road surface, shoulder and upper slope due to rain and rain. And the rain-crack prevention sheet attached to the mat body exhibits a rain-crack prevention effect from the middle of the slope to the bottom by fixing. In addition, since the weight is only a few kilograms than conventional sandbags filled with soil, it can be easily transported and installed on the shoulder, etc. Water and mud such as rain and snowmelt flowing from the shoulder to the slope In addition to preventing runoff, it is possible to prevent erosion of the entire bare slope and to replant with seeds and seed sheets contained in the mat body at an inexpensive price.
