摘要：PROBLEM TO BE SOLVED: To provide a side-ditch structure and a wall surface structure easy to carry, shortening a construction period and furthermore reducing the amount of excavation. SOLUTION: The respective lower ends of a front wall part 11 and a rear wall part 12 of a variable side-ditch 10 are connected by invert concrete 13 and installed on foundation concrete 14. A flexible frame 16 horizontally extending in a back face direction is fixed from the back face side of the rear wall part 12. The frame 16 is formed of honeycomb structure of a plurality of cells that can be filled with a back-filling material. Part of a side wall of the frame 16 is hooked to L-shape bars 17 with one ends connected to inserts of the rear wall part 12, and the upper ends of the L-shape bars 17 are fixed as a pair by nuts 21a using a slip-off preventing plate 20. The slip-off preventing plate 20 is also fixed in a simple manner to the rear wall part 12 by a bolt 19a through an L-shape plate 18a. COPYRIGHT: (C)2007,JPO&INPIT
