PURPOSE:To shorten the period of construction by a method in which a shore- strut frame is set between steel columns facing each other, panels are set in the direction of crossing the shore-strut frame between the steel columns, and while excavating the ground between the panels, the steel columns and the panels are alternately penetrated. CONSTITUTION:A shore-strut frame 2 is fitted into the frame receiving groove 12 of steel columns 1, and pins 14 are inserted into two upper and lower holes 13 to prevent the vertical movement of a vertical plate 22 to form a framework. A panel 3 is inserted into the grooves 11 of the steel columns 1 facing each other and pushed down, the ground between the panels 3 is excavated, the drainage tubes, etc., are hung down ad embedded with soil. In constructing the final end portion of the trench, the panels 3 instead of the shore-strut frame 2 are fitted into the grooves 12 to form a formwork, and then the same operations are made. |
