から、伸縮自在のいわゆる展張体であるのが好ましい。FIG. 1 is a partially cutaway perspective explanatory view of an example of the plastic honeycomb for civil engineering structures of the present invention. As shown in FIG. 1, a plastic honeycomb 1 is made up of a plurality of honeycomb-shaped cores 2 formed into polygonal shapes such as quadrangles and hexagons in plan view. From the viewpoint of convenience in transportation, it is preferable to use a so-called expandable body that can be expanded and contracted.

いる。The material of this plastic honeycomb 1 is a thermoplastic resin such as polyethylene (PE), polypropylene (PP), or polyvinyl chloride (PVC), which is coated with carbon blank or ultraviolet deterioration to improve weather resistance. An inhibitor or the like may be added. This plastic honeycomb l has two or more through holes or cut grooves 3 bored through the core side wall at two or more locations.

This means that there are through holes or cuts in the core side wall of the plastic honeycomb 1 that extend through the core side wall at two or more locations. 83, which reduces the strength of the plastic honeycomb 1 itself.
This is to compensate for this decrease in strength. Examples of organic fibers include nylon fibers, polyester fibers, polyacrylonitrile fibers, and the like.

ことが可能となる。As explained above, according to the present invention, since the through holes or grooves are formed in the core side wall of the plastic honeycomb constituting the civil engineering structure, water such as rainwater and seawater that has entered the civil engineering structure can be absorbed through the through hole. Or, since it can be moved through a cut groove, drainage can be carried out smoothly. For this reason,
Erosion can be prevented for a long period of time. In addition, by forming the above plastic honeycomb by blending 10 to 40% by volume of organic fibers or inorganic fibers with thermoplastic resin such as PE, PP, or PVC, it is possible to form through holes or grooves in the core side wall. It becomes possible to sufficiently compensate for the decrease in strength of the plastic honeycomb due to the angle of 4°.
