Abstract

This research investigates the deployment of waterproofing technologies in construction, with a specific focus on augmenting worker safety, work environment, and solve the difficulty of securing skilled workers. Implementing liquid waterproofing cement equipment resulted in a remarkable increase in adhesion performance by around 20%, coupled with a twofold acceleration in operational speed. The application of primer spraying apparatus led to a two-fold improvement in both penetration and adhesion performance, concurrently boosting the work speed by approximately the same factor. With urethane spraying equipment, the workload could be reduced to a third for the same layer thickness, adhesion performance enhanced by approximately 1.4 times, and workability improved by about 1.4 to 1.5 times. These findings suggest that such technological interventions can potentially enhance work efficiency, improve the quality of output, and mitigate safety accidents that are commonplace in manual operations. Furthermore, these advancements present promising solutions to the ongoing challenges of sourcing highly-competent workers in the industry.

이 연구에서는 방수공사의 장비 활용 시공기술을 통해 작업환경 개선으로 인한 작업자의 사고방지 및 안전을 확보하고, 장비의 활용에 따른 작업 효율성 증대 및 품질을 개선시키며 더불어 기능공 확보의 어려움을 해소하는 것을 목적으로 하고 있다. 시멘트 액체 방수 뿜칠장비를 활용함으로써 부착성능이 약 20% 향상하고 작업속도가 2배 상승하였다. 프라이머 뿜칠 장비를 활용함으로써 침투성능과 부착성능이 약 2배 개선되는 효과를 보였고, 작업속도가 약 2배 상승하였다. 우레탄 뿜칠 장비를 활용함으로써 동일한 도막두께를 확보하는데 작업량을 1/3로 단축할 수 있으며, 부착강도는 약 1.4배 증가하는 결과를 나타내었고, 작업성이 약 1.4~1.5배 향상되었다. 이러한 결과로부터 장비 작업 시 품질향상과 더불어 작업효율이 증대되고, 수작업 환경에서 자주 발생하는 안전사고를 방지함으로써 안전 환경 조성에 기여할 수 있다. 또한 기능공 수급에 대한 어려움 해소가 가능할 것으로 판단된다.
