METHOD FOR PREVENTING SOIL STRUCTURE FROM SLIDING AT SLOPE SURFACE LAYER WITH GEOCELL FIXING OPERATION AUXILIARY MEANS

摘要

PROBLEM TO BE SOLVED: To provide a method for preventing soil structure from sliding at slope surface layer with a geocell fixing operation auxiliary means with a combination of natural ground reinforcement means and a slope surface protector which provides an excellent workability for embankment or destructionable natural ground or narrow ground; meets environmental requirements, such as vibration or noise upon operation; provides uniform quality and effect; and provides an excellent appearance, durability and economical advantage.SOLUTION: There is provided a method for preventing soil structure from sliding at slope surface layer with fixing operation auxiliary means for geocell 6. After accomplishment of boring of a hole having a designed depth, with a water stopper (sealing tip end of the hole by inserting an iron ball and the likes), cement paste 3A from tip end of a drill bit 1 is ejected from a side hole arranged on side surface of a drill rod or the drill bit 1. By virtue of elevating/lowering movement of the drill rod and rotational movement of the drill rod as a hollow steel shaft within a designed region to be improved, mixing improvement with natural ground part within the region to be improved is executed so as to form a designed improved diameter.
