STEEL FRAME FOR ROCK FILLING

PURPOSE: To improve efficiency in execution of work by a method wherein a steel joint, available for joining by means of vertical insertion, is provided vertically to the side of a steel frame, and the joint provided on a steel frame adjoining a precedently installed steel frame is inserted vertically into the joint of the precedently installed steel frame. CONSTITUTION: A preceding steel frame A1 is installed with a crane to a specified position, and a succeeding steel frame A2 is hoisted down and installed to an adjoining position. Then, a T-shaped joint 20 of the frame A2 is inserted into a C-shaped joint 21 of the frame A1 , and thereby the frames A1 and A2 are connected together. A stable and strong large-sized structure for rock filling is installed with a desired number of frames A1 and A2 ... connected transversely with one another. As occasion demands, the joint may be formed in hook shape, or joints may be provided on the reverse side of the steel frame, and such joints can be connected with hook joints provided in projection to a revetment made from steel sheet piles, and a rock fill part is formed to the front of the revetment. Thereby, connection can be made simply, yet certainly, while improving strength and furthermore, environmental improvement can be achieved by remodeling a steel sheet pile revetment into a rock fill revetment.
