| Title of the article | Foundations strengthening by pressure cementation method in the rammed pits |
| Abstract. | Due to the ground base property deterioration because of the long soaking, foundations in rammed pits of an apartment building on the Tatarstan street in the city of Naberezhnye Chelny received a significant settlement. Therefore, part of the building is currently in critical condition. Based on the engineering geological conditions of the site and the building condition analysis developed a technical solution for foundations strengthening. For ground base strengthening proposes a variant of the pressure cementation method, defined technological parameters to perform injection works. In the process of cement mortar injecting into the ground under the base pressure, the mortar enters into the weakest area of the array and creates a rigid reinforcing element from solidified mortar. Ground array after strengthening can be considered as a complex composite system, consisting of rigid reinforcing elements, compacted ground regions around these elements and uncompacted ground regions. The authors performed the evaluation of the ground compressibility characteristics, predicted after strengthening works, at the same time were used the results of experimental researches. According to calculations, the grounds strengthening can significantly increase the ground array deformation module and avoid further deformation of the building. |
