A prefabricated soil retaining system for trench excavation is provided to perform an excavation work economically and stably by installing a prefabricated soil retaining wall simply in case of small cross-section and low depth excavation work. A prefabricated soil retaining system for trench excavation is constructed by connecting prefabricated walls(1) and columns, connecting prefabricated wall columns to be located at the right and left sides of an excavation of small cross section using hydraulic jacks or screw jacks(3), placing the prefabricated wall columns in the excavation and applying hydraulic pressure to make a retaining wall and the excavation in tight contact with each other, and after completing the work at the excavation, reducing hydraulic pressure and releasing joints(4) of the excavation and the retaining wall. |
