TUBE MATERIAL UNIT FOR TRANSMISSION TYPE SAND ARRESTATION DAM AND TRANSMISSION TYPE SAND ARRESTATION DAM

摘要

PROBLEM TO BE SOLVED: To provide a transmission type sand arrestation dam that has a damaged member easily replaced and enables a direction in which strength against a design impact load is high to be selected according to a vector of the design impact load, and a tube material unit used therefor.SOLUTION: The present invention relates to a tube material unit 1 for a transmission type sand arrestation dam provided along a width of a water channel, the tube material unit comprising a tube material (thin tube 70) having a flange at an end. The flange is formed obliquely to a vector of a design impact load on the tube material (thin tube 70).SELECTED DRAWING: Figure 6
