| titleOfInvention | Columnar compact for ground improvement and ground improvement method |
| abstract | (57) [Summary] [PROBLEMS] To reduce the size of a drilling hole accompanying the downsizing of an execution machine, to ensure that the drilling hole can be filled with an expanding material. Another object of the present invention is to provide a ground improvement method capable of reliably filling an oblique or horizontal hole with an expanding material when the ground is improved immediately below an existing structure. SOLUTION: A cylindrical member for ground improvement is formed by forming a cylindrical member having a predetermined length with a material having impregnation and water permeability, and filling the cylindrical member with a material having water-swelling properties such as quicklime. Manufactured, the columnar compact is injected and filled into a number of drill holes made on soft ground saturated with groundwater to form a columnar group, and then material expansion due to impregnation of groundwater causes confinement of the ground inside the columnar group Take measures against compaction of the ground due to pressure increase, liquefaction based on the effect of increasing density, and bearing capacity. In addition, the improvement effect in the ground is made uniform for the improvement effect in the ground by selecting and arranging cylindrical shaped bodies with different expansion performances in advance for multiple drillings with different angles, sizes, etc. That you did. |
