REINFORCEMENT CONSTRUCTION METHOD OF POOR SUBSOIL BY HORIZONTAL GEOGRID AND VERTICAL GEOGRID

摘要

PURPOSE: A reinforcing method of the weak ground using horizontal and vertical geogrids is provided to improve the durability of a building by using the horizontal and vertical geogrids on the weak ground where columns of the building are located. CONSTITUTION: A reinforcing method of the weak ground using horizontal and vertical geogrids is as follows. The ground is excavated. The bottom(40) of the excavated ground is hardened. A first horizontal geogrid(10) is installed on the hardened bottom. Vertical geogrids(20) are installed in parts where the columns of a building are located. A primary reinforced soil layer(50) is formed by filling the top of the vertical and first horizontal geogrids with reinforced soil(41) and hardening the filled reinforced soil. A second horizontal geogrid(10-1) is formed on the primary reinforced soil layer, and vertical geogrids are located at the top of the second horizontal geogrid. The processes are repeated.
