CONSTRUCTION AND DEVICE OF PREPACKED CONCRETE DAM AGAINST DEBRIS FLOW

摘要

PURPOSE:To easily build a high-strength dam by a method that, after box-shaped containers are connected, rubble stones are packed in them, and mortar is poured. CONSTITUTION:The fronts 7 having a grating-shaped slope, sides 8 and 9 with convex fittings 12 and/or concavity fittings 13 and backs 7' are assembled to box-shaped containers respectively at a construction field. The containers 1, 2 and 3 are joined together by connecting the fittings 12 and 13 to form the front of a dam. Then, the back of the dam is formed by joining box-shaped containers 4, 5 and 6 together. And the front and back of the dam are connected with coupling members 17. After panels 16 are fixed to the front and back of the dam, rubble stones are packed in each space between frames from the top 10, and mortar is poured.
