EARTH RETAINING METHOD UTILIZING BAMBOO VEGETATION

PROBLEM TO BE SOLVED: To prevent the collapse of a slope of mountain, forest, and land developed for housing lot, restore the slope collapsed by disaster, resin earth powerfully to improve a bank of river and lake, match with ambient environment, simplify the work execution, and reduce cost. SOLUTION: The nature that a bamboo 2 of a bamboo kind represented by Bambusa takes root and sprouts from a joint part in contact with the earth, and the root (c) extends downward and powerfully is utilized to retain earth and perform greeing. As a work execution method, a bamboo material obtained by cutting a bamboo in two or three days (up to five days to the maximum extent) after it is cut to a length of two stems and three joints or more is used, water is poured into a stem part between the joint and the joint of the bamboo material, the joint on one end side of the bamboo material is slightly exposed on a ground surface (g), and the joint on the other end side is embedded into the ground obliquely at a depth of 10 centimeters or less. Or, the bamboo material is spread over the arranged piles 3 to form a bamboo fence and bury it by the earth on its back.
