Abstract

The steel grating discussed in this study is a drain cover that enhances the rigidity of the steel frame using an inclined inflow tract for wastewater, facilitates smooth drainage, and prevents the escape of bad smell from the drain. Recently, the urban problem of bad smell in sewerage lines has been hindering the improvement of living standards. Moreover, the frequent failure of existing products deters bad smell prevention measures and results in administrative power and budget wastage. The pressure to reduce budgets propels the increased demand for functional steel grating. Thus, this study focused on optimizing the design parameters of a steel grating by simultaneously considering its rigidity and drainage efficiency.

본 논문에서 연구한 스틸그레이팅이란 배수로 덮개로 오수 또는 우수의 경사진 유입로를 형성하여 견고성을 증가시키고, 배수를 원활히 하며, 배수관로 내부의 악취 확산을 방지할 수 있는 배수로 덮개를 말한다. 근래에 생활수준 향상 등으로 인해 도시의 악취 문제가 대두되고 있다. 하지만 기존 제품들은 잦은 고장 등으로 인해 악취 저감 기능을 상실하고 이로 인한 행정력과 예산 낭비를 초래하고 있다. 또한 악취 저감 스틸그레이팅 수요 증가에 따라 예산 절감의 필요성이 대두되고 있다. 따라서 본 연구에서는 다구찌 기법과 솔리드웍스를 이용하여 강성적 측면과 배수 성능적 측면에서 스틸그레이팅의 설계 파라미터를 동시적으로 최적화시키고자 하였다.
