    • PURPOSE:To reduce the construction period by supporting a a working floor which can be freely raised and lowered onto a landslide protecting wall and laying concrete into a mold frame which is assembled on the working floor and excavating the under part of the working floor and lowering the working floor and repeating the similar execution. CONSTITUTION:A landslide protecting wall 1 is constructed onto a ground A, and after a temporary steel column 2 is constructed, the first excavation is executed. Then, a working floor 4 is supported in free elevation and lowering onto the temporary steel column 2, and after a mold frame 5 for the first floor is assembled on the working floor 4, concrete 6 is laid into the mold frame 5, and at the same time, the second excavation in the lower part of the working floor 4 is executed. Then, the mold frame 5 is disassembled, and the first floor is constructed, and then the working floor 4 is lowered, and press-attached onto the landslide protecting wall 1. The underground first floor mold frame 5 and an underground first stay mold frame are assembly-supported on the working floor 4, and concrete 6 is laid into each mold frame, and the underground first floor body is constructed. Further, the bodies of the underground second floor, etc., are constructed similar, and when the final excavation in the lower part of the working floor 4 is completed, the foundation beams are constructed for the excavation lower part, and then the working floor 4 is removed, and the final body is constructed.
