Soft Ground Strengthening Structures Using Files and Geogrids

摘要

The present invention relates to a soft ground strengthening structure using support piles and geogrids and, more specifically, to a soft ground strengthening structure using support piles and geogrids. The soft ground strengthening structure comprises: the support piles which include a plurality of main fixtures provided between a soft ground layer and a piled soil layer to be longitudinally distanced from each other at regular intervals, an auxiliary fixture passing through each of the main fixtures to be inserted and provided therein and having an end protruding to a lower end of the main fixture, and a locking fixture provided inside the main fixture to fix the auxiliary fixture and the main fixture; and the geogrids disposed between the soft ground layer and the piled soil layer to be longitudinally distanced from upper portions of the main fixtures laterally distanced from each other at regular intervals. The auxiliary fixture is inserted from a lower portion of the piled soil layer via the soft ground layer into a lower support layer. The main fixture is inserted into the auxiliary fixture, and then the geogrids are installed on the main fixture to form a rigid reinforcement layer. The auxiliary fixture is fixed by using the locking fixture to strongly install the support piles, thereby strengthening the support of the soft ground.
