Description

  The present invention is designed to reduce the amount of snow on roads and railway lines in winter and to reduce visibility damage, or to prevent wind damage. The present invention relates to a windbreak snow fence to be installed in a snow forest to protect between young trees, particularly to a foundation structure for installation in a soft ground area.

  In the conventional snow fence, a concrete block is embedded in the ground as a foundation, a pillar is set up on the foundation concrete, and a snow plate and a snow net are spanned between the pillars.

  For example, as disclosed in Japanese Patent Application Laid-Open No. 10-18233, there is known a structure in which a cubic foundation concrete is embedded in the ground, and a pillar is erected on the foundation concrete with an anchor fitting. This foundation concrete is relatively large and heavy so that the pillars do not fall over due to the wind force received by the snow plates and snow nets.

Japanese Patent Laid-Open No. 10-18233

  For example, in a place that was originally a wetland, a peat layer where the plant has not completely rotted accumulates thickly, forming a soft ground zone. Even if heavy foundation concrete was buried in such soft ground, there was a problem that the pillars fell due to uneven settlement.

  Also, windbreak snow fences installed by the windbreak snow forest to protect the young trees need to be removed when the windbreak snow forest grows, but it is troublesome to remove even the part buried in the ground.

  Therefore, the present invention is to provide a foundation structure of a windproof snow fence for a soft ground area that is difficult to unequally sink even in a soft ground area, and is environmentally friendly to return to the soil naturally without removing the buried part in the ground. With the goal.

  The foundation structure of the windproof snow fence for the soft ground zone of the invention of claim 1 is composed of a foundation pile 1 buried in the ground at equal intervals, a connecting pipe 2 covering the upper end of the foundation pile 1, and a connecting pipe 2 The foundation pile 1 is embedded by vertically driving a long and narrow natural tree in a support frame 11 that is inserted and arranged on the ground surface, and a wind protection snow fence with a wind protection snow plate or a wind protection net 14 interposed between the support posts 11. The connecting pipe 2 is buried in the middle of the ground, and the rooting material 3 is buried in the ground in the horizontal direction on the left and right sides of the connecting pipe 2, and the rooting material 3 is a long and narrow natural tree.

  According to the first aspect of the present invention, the foundation pile 1 buried in the ground at equal intervals, the connecting pipe 2 covered on the upper end of the foundation pile 1, and the foundation pile 1 are buried by driving a long natural tree vertically. Since the connecting pipe 2 is buried in the middle of the ground, and the rooting material 3 is buried in the ground horizontally on the left and right sides of the connecting pipe 2, the heavy foundation concrete is not used and the rooting material 3 is the foundation pile 1 Therefore, it becomes difficult to unequally sink even in soft ground.

  In addition, the foundation pile 1 is embedded by vertically driving a long and narrow natural tree. Since the rooting material 3 is embedded in the ground in the horizontal direction on the left and right of the connecting pipe 2, the rooting material 3 is a long and narrow natural tree. Since the underground foundation pile 1 and the root timber 3 are natural wood, they will be environmentally friendly and naturally return to the soil without removing the part embedded in the ground.
