PROBLEM TO BE SOLVED : To provide an easily constructible and economical earth retaining construction method, capable of performing earth retaining also serving as seeding and planting by bamboo vegetation in a geologically weak place, for example, volcanic ash deposit land, particularly, its slope and even a wholly gravel (piece earth) place, regardless of the geology. ŽSOLUTION : Disaster preventive sandbags 2 are juxtaposed in large numbers, for example, on the volcanic sash deposit land 1. Volcanic ash 3 gathered at a job site is packed, and hedge bamboo 6 in a wrapped-in state by putting a root part in a small sandbag 5 charged with barrow 4, is planted in its volcanic ash, and is made to function as strong earth retaining function when roots of the hedge bamboo 6 lengthen in addition to the earth retaining function of the sandbag itself. This earth retaining construction method can be similarly performed even in the wholly gravel (piece earth) place such as a disaster recovery site. ŽCOPYRIGHT : (C)2008, JPO&INPIT Ž |
