토석류 실험을 위한 3D 프린터를 활용한 사방시설 모형제작에 관한 연구
2015
Lately, abnormal temperature is resulting in a lot of disasters for localized torrential rain, typhoons, or severe rain storms. Among them, debris disasters, damages taking place in mountains, are increasing. The typical examples of debris disasters that happened lately are Seoul Woomyeon Mountain disaster in July, 2011 and Chuncheon Cheonjeon-ri disaster. For such cases of disasters, people are more and more attentive about debris flow disasters. There are many ways to reduce debris flow. But in Korea, installing a debris flow control dam to reduce debris flow is the most frequently adopted method. The debris flow control dam is a facility playing roles in reducing debris flow to lessen the damage. In Korea, there are more and more debris flow control dams installed however, after installing them, only structural examination is conducted on them, but it is hard to verify their roles before actual debris flow takes place. Therefore, to verify those debris flow control dams’ roles, this study utilizes 3D printing technology directly applicable to perform a debris flow experiment to design a debris flow control dam model and introduces the process of building it. Since 3D printers allow us to make a model almost the same as the real debris flow control dam, first, this author selected the debris flow control facility (ex: the transmission-type, non-transmission-type) to be used in the debris flow experiment, used CAD to design the drawing of the model, adjusted the section with the scale appropriate for the waterway used in the experiment, and then finally designed the section as a 3D form. Based on that, this researcher used a 3D printer and designed the debris flow control dam model finally. The debris flow control facility model designed here will be applied directly to the debris flow model experiment to be conducted in follow-up research.
