By the way, the post fixing method using a concrete structure has the following disadvantages. That is, in order to make a concrete structure, the installation and disassembly of the formwork, and the concrete placing and curing work must be performed every time, so the basic work process for fixing the post is complicated and the construction time is excessive.

Moreover, when the construction is high or on slopes, there are many difficulties in the transportation and construction of formwork and concrete raw materials.

In addition, the strut fixing method using the concrete structure, for example, it is difficult to recycle the waste concrete structure in the case of aging and breakage of the guide sign panel or pan, and additional costs for the disposal process of the waste concrete structure.

In particular, since more than 90% of the concrete raw material is poured into the ground, the surrounding soil is changed by the leachate contained in the raw material, which may be a factor causing contamination of the soil and groundwater.

In order to improve the problem of environmental pollution, a method of fixing the strut by filling the inside of the FRP box structure has been proposed, but this method is satisfactory construction stability by causing frequent breakage of the box structure, especially when water freezes easily in winter. Is difficult to obtain.
