The present invention relates to a construction method for the filling section to prevent the collapse of the landscape stone, and more particularly, a construction method using an anchor bolt for retaining wall fixing to connect the geogrid and the foundation stone and the upper stone supporting the foundation stone and the upper stone with excellent binding force. By presenting, the foundation stone and the upper stone is installed and maintained in a stable structure relates to the construction method of the fill section to prevent the collapse of the landscape stone can prevent the safety accidents caused by the collapse of the fill section.

In general, civil engineering or construction sites should consider reinforcement of the cut surface formed by cutting the rock part or the ground, or reinforcement of the slope of the fill part generated between different areas in the process of laying the ground.

The cut section is a structure with respect to the inclined surface having a slope formed by an arbitrary incision, and the fill section is a structure with respect to the inclined surface formed with an altitude difference in the process of filling.

Here, the cutting surface and the inclined surface may be presented a construction method for reinforcement in various ways. Among them, reinforcement construction method considering landscaping considering external aesthetics as well as safety and economic efficiency should be applied.

In general, in order to reinforce the inclined surface of the fill portion, a retaining wall structure using concrete pouring or a stone wall structure using landscape stone (natural stone) may be presented.

However, the retaining wall structure using concrete pouring lacks flexibility and variability corresponding to shapes of slopes and rocks to be installed. And a support base is needed to solve the flexibility and variability, but a considerable space is required to secure the support base. In addition, the securing of such space requires a lot of backfilling work, and thus the construction period is extended, and construction costs are high. In addition, in the case where a partial breakage of the retaining wall structure occurs in the future, repair thereof is difficult, and it is difficult to satisfy the landscape aspect in consideration of aesthetics.

In addition, in the case of the stone wall structure using the landscape stone, the landscape aspect is satisfied, and flexibility and variability corresponding to the inclined surface can be secured, but when the stone is stacked together with the fill, it is difficult for the natural stone to be kept upright, If you are not an experienced contractor, there was a problem that natural stone collapses easily.

In order to solve the problems described above, after arranging the landscaping stone, laminating a plurality of compaction layers with high quality earth and sand on one side of the landscape stone, and placing and binding the geogrids on the compacted layer, the landscape stone and the geogrids mutually The construction method has been proposed to connect the landscaping stone firmly fixed to the geogrid to prevent the collapse of the landscape stone.
