管溝開挖崩塌防止技術研究

Techniques to Prevent Trench Cave-in Fatalities

本文探討擋土防護裝置的設計，以防止管溝崩塌造成災害，據此保障勞工安全。首先依據職業災害報告，整理災害發生的情況，以及從事現場訪談，收集施工人員的經驗。然後根據現存專利，從事擋土防護裝置之設計，提出了五種擋土防護裝置的設計構想，並探討實際可行性。最後，本研究以輪盤式為對象，探討其設計考量因素，以及使用此裝置之作業程序與限制。

The purpose of this research is, for the sake of workers’ safety, to design shielding devices to prevent disasters caused by trench cave-in. First, different situations of the careers damage were arranged in accordance with previous reports. Then by personally interviewing with workers in many construction sites, useful information were collected. Afterwards, based upon extant patents, five different designs of shielding devices were proposed, and their practicability was simultaneously evaluated. At last, Wheel-Type shielding device was used as the object in this research to investigate the designing factors, operation procedures, and limitations.
