EARTH RETAINING METHOD UTILIZING ANGLE BAR AND ANGLE BAR THEREFOR

摘要

PURPOSE:To provide easy and low-cost framework composition and earth retaining work by a method wherein channel bars are utilized together with angle bars each of which is produced by forming the vertical rib on the angle bar with pairs of cuts at regular intervals and bend down the vertical portion of the cuts. CONSTITUTION:An angle bar 5 having a vertical rib 1 and a horizontal rib 2 is formed in the rib 1 with pairs of cuts at regular intervals, and the portion of each pair of cuts is bent down by 180 deg. through the opposite side of the rib 2 to form an anchor piece 4. A plurality of angle bars 5 provided with the anchor pieces 4 are arranged askew on a slope face 6 in parallel with each other. Open-top channel bars 10 with ribs 8 and 9 lower than the vertical rib 1 of the bar 5 are each placed on each aligned set of the piece 4 of the angle bar group. After the bottom members 11 of the channel bars 10 and the horizontal ribs 2 of the bars 5 are fixed by fixing means 12 such as bolts, soil 14 is filled on the slope face 6 until it is substantially level with the ribs 8 and 9, to complete earth retaining work.
