ABSTRACT:
A method which includes excavating a first pilot trench and a second pilot trench, shoring up said first pilot trench, forcing two lines of plate means vertically downwardly into the earth to a level substantially below the level of the bottom of said first pilot trench, excavating the material between said two plate means so as to form a deep trench disposed below said first pilot trench, inserting pipe sections into said trench, withdrawing said plate means vertically upwardly, covering said pipe sections with earth, supporting the shoring framework at approximately ground level while advancing the trench shoring frame horizontally into said second pilot trench, said advancement being achieved by applying hydraulic pressure between said shoring framework and an end wall that is pressed against earth deposited rearwardly of said first pilot trench.
