Underground foundation construction method using compaction grouting

摘要

The present invention relates to a method for constructing various types of foundations in the ground of a soft ground made of a uniform soil material, in which a hollow file is inserted at the ground without constructing a ground by excavating the ground surface, The grout discharges the ground with the pump with the strong earth discharge and the grout presses the soft ground to form the desired space. The grouting time and the position of the hollow pile are moved. It is possible to appropriately control the amount of the discharged grout so as to adjust the diameter of the grout grout in the space formed by pressing the soft ground so as to construct various types of foundation at any position in the ground without any operation such as depressing the ground surface Softened ground by consolidation by grout Securely to the invention, which can achieve the effect to improve the soil.
