Abstract

The purpose of this study is to compare and analyze the performance and work productivity of wet type pavement cutters and sludge suction type pavement cutters (hereinafter referred to as automatic pavement cutters) developed to reduce scattering dust. We first investigated the development status of wet type manual pavement cutters that are mainly used in Korea and automatic pavement cutters, and analyzed the pavement cutting work in detail. And the standard cutting performance was derived by measuring the cutting time by depth by applying the two equipment to the test bed under the same conditions. However, there is a limitation that the data measured in the test bed does not reflect the various variables of the actual pavement cutting site. Therefore, in this study, data was collected through field surveys, and the correlation between cutting distance and time was analyzed, and then a model for calculating the productivity of pavement cutters was presented through simple regression analysis. As a result of comparative analysis of the values derived from the regression equation with the standard cutting performance derived from the test bed, the cutting performance derived through the regression equation showed a similar trend to the standard cutting performance. Finally, we verified the usability of the automated pavement cutter developed by qualitatively analyzing three tasks that are difficult to measure quantitatively but affect productivity.

본 연구는 국내에서 주로 사용되는 습식 도로절단기와 비산먼지 저감을 위해 개발된 슬러지 흡입식 도로절단기(이하 자동식 도로절단기)의 작업생산성을 비교 분석하여 자동식 도로절단기의 성능 및 활용성을 검증하는 것을 목적으로 한다. 이를 위해 먼저 국내에서 주로 사용되는 습식 수동식 도로절단기와 자동식 도로절단기의 개발 현황을 조사하고, 도로 절단 작업을 세부적으로 분석하였다. 또한, 동일한 조건의 테스트베드에 두 장비를 적용하여 깊이별 절단 시간을 측정하여, 표준절단 성능을 도출하였다. 하지만 테스트베드에서 측정된 데이터는 실제 도로절단 현장의 다양한 변수를 반영하지 못한다는 한계가 있다. 따라서 본 연구에서는 현장 조사를 통해 데이터를 수집하여 절단 거리와 시간 사이의 상관성을 분석한 후, 단순회귀분석을 통해 도로절단기 생산성 산정모델을 제시하였다. 회귀식에서 도출된 값을 테스트베드에서 도출한 표준절단 성능과 비교 분석한 결과, 회귀분석식을 통해 도출한 절단 성능은 표준절단 성능과 유사한 경향을 보였다. 마지막으로, 정량적으로 측정하기는 어려우나 생산성에 영향을 주는 세가지 세부작업에 대해 정성적으로 비교 분석하여 개발된 자동식 도로절단기의 활용성을 검증하였다.
