【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、畑の周辺や海辺あるいは河川や海岸に張設して飛砂や流砂などを防 止する砂防シートに関するものである。 The present invention relates to a sabo sheet which is stretched around a field, on the seaside, on a river or on the coast to prevent flying sand and quicksand.

【0002】[0002]

【従来の技術】[Prior Art]

従来、風の強い地方や平野地、海辺の畑などの周囲には、風による飛砂の防止 を兼ねた風避けに、粗朶や藁を用いて垣根を作ったり、低木の植え込みが作られ ている。また、海辺の砂防方法として、合成繊維糸で作られたメッシュ編織布を 張設することも行われている。 Conventionally, in areas around windy regions, plains, and fields on the seafront, fences and bushes have been planted using rough stalks and straws to prevent wind blown while also preventing sand blown by the wind. There is. In addition, a mesh woven fabric made of synthetic fiber yarn is also stretched as a seaside erosion control method.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、従来の粗朶や藁を用いた垣根による砂防法では、材料の入手や 垣根の構造上などから設置高に限度がある。この砂防垣根を高くすると風圧を増 して倒伏することがあるばかりではなく、風の流れが垣根の越流となるため飛砂 を十分に捕集することができない。また、砂防用メッシュ編織布も飛砂を十分に 捕集するように目開きを小さくすると、風圧の影響が大きくなるので、飛砂の捕 集の効率を高めて風の抵抗を小さくするためには、複数枚のメッシュ編織布を組 み合わせて張設せねばならず、設備費が高くつくなどの問題があった。一方、流 砂対策としては殆ど行われていないのが現状である。 However, in the conventional sabo method using fences that use rough wood and straw, the installation height is limited due to the availability of materials and the structure of the fence. If this sabo fence is raised, the wind pressure will not only increase and it may fall, but the flow of wind will overwhelm the fence, and it will not be able to collect enough sand. In addition, if the mesh opening for the erosion control mesh is made small so that the sand can be sufficiently captured, the influence of wind pressure will increase, so in order to improve the efficiency of sand collection and reduce the wind resistance. However, there is a problem in that equipment costs are high, because multiple mesh knitted fabrics must be combined and stretched. On the other hand, the current situation is that almost no countermeasures against sediment transport are taken.

【0004】 従って、本考案の目的は、軽量で取り付けが容易な、砂防効果に優れ、高い耐 久性を有する砂防シートを提供することにある。Therefore, an object of the present invention is to provide a sabo sheet which is lightweight, easy to install, has an excellent sabo effect, and has high durability.

That is, a polyethylene film of a certain size was laid on the back side of the stretched sheet-like material, and the flying sand that had permeated the sheet-like material was collected for a certain period of time. The amount of sand permeation of the sheet-like material was about 21% of the amount of sand permeation of the sheet-like product of the comparative example, and it was confirmed that the sheet was excellent in erosion control effect.
