(Points of interest)
In Japan, although the latitude is relatively low, seasonal wind blowing from the continent in winter caused a snow cover in a wide area of the country. Especially in the snowy area, the handle was taken by the heel, the visibility was suddenly closed due to the visibility deterioration caused by the snowstorm, the local snowstorm that occurred locally, the snow smoke that the front vehicle rolled up, etc. The risk of frequent accidents increases due to various factors, and various forms of things such as blowout fences, blowout fences, and blowout prevention fences are provided to ensure safety on such roads. Is selected and installed according to weather conditions, roadside environment, road structure, etc.

    A typical snow fence has a plurality of pillars driven into the soil at predetermined intervals along the road side that is the windward side of the snowstorm on the road, and a plurality of windbreak snow boards are hung between these pillars. It is designed to be temporarily fixed so that it can be handed over and detached, but the struts that have been erected directly on the roadside ground in the form of piles are used for thawing snow from the gap between the base end of the strut and the ground. Rainwater and the like are easy to invade, and there is a risk that they will gradually tilt or collapse due to long-term use.

(Conventional technology)
Considering this situation, for example, as represented by the following proposed in Patent Document 1 (1), an L-shaped basic block is arranged in a cut-out portion provided on the slope of the road side. The foundation main block is placed and fixed between several L-shaped foundation blocks, and the lower struts are attached to the reinforcing bars embedded in the foundation main blocks. A few steps of snow-proof boards are attached so that the angle can be adjusted, and the foundation part is reinforced, or it is integrated into the block concrete foundation embedded in the ground, as seen in Patent Document 1 (2) In some cases, anchor bolts are fixed firmly by tightening the base plate of the column mounting base with respect to the anchor bolt that protrudes to the ground with the tip facing upward.

However, the foundation for the snow fence device as shown in the former Patent Document 1 (1) has to be laid with an L-shaped foundation block over the entire installation range of the snow fence device. However, the foundation for a snow-breaking snow fence as disclosed in the latter patent document 1 (2) is a shallow area where the block-shaped concrete foundation is underground. However, there is a drawback that the snow fence is likely to roll over or collapse, especially on soft ground and on the side of the valley where snow melts easily flow.
