Description

  The present invention relates to an assembly-type anti-scattering net that surrounds the periphery of a road when excavating the surface of the road for the purpose of repair or the like and prevents the excavation debris from scattering.

  For example, when repairing the surface of a road (concrete or asphalt), it is necessary to excavate the surface of the road with a power tool, etc., but at that time, a large amount of excavation waste is generated, which travels nearby. A situation occurs where the user falls to a car or a nearby house.

  Conventionally, in order to prevent such a situation, a plate-like member (horse) is leaned on a portion of the road surface to be excavated, or five sides including the upper side of the excavated portion are covered with a net material.

  However, in the conventional technique in which the plate-shaped member (horse) is leaned, there is a problem that it is not possible to exert a sufficient scattering prevention effect because only one surface direction is prevented from scattering. In addition, in the conventional technology that covers four or five sides with net material, lightweight and small ones are weak against wind pressure, but they are easily blown away or defeated by wind, while large and heavy ones are strong against wind pressure. There is a problem that handling such as transportation and assembly is troublesome.
