An Experimental Verification on the Development of an Innovative Diamond Wire Saw Cutting Technology 원문보기

This paper introduces a innovative diamond wire saw cutting technology and its experimental verification that can be utilized for cutting heavy structures. While conventional diamond wire saw cutting technologies such as water cooled cutting method and dry cutting method cause severe environmental problems due to generating massive concrete sludge or dust scattering, the proposed method can eliminate those problems considerably. Through extensive experiments using heavy structure test bed and real bridge pier structure, comprehensive analysis and comparative evaluation about various cutting methods were performed. As a result, the innovative diamond wire saw cutting method could achieve a similar cutting and cooling performance to the water cooled cutting method without generating concrete sludge and it showed an improved cutting and cooling performance to the dry cutting method without dust scattering. Consequently it is confirmed that the suggested cutting technology can be a promising environment-friendly alternative in the field of heavy structure dismantling.

문제 정의

Furthermore, two testbed verification experiments and a field application verification experiment for a full-scale concrete bridge were carried out for the developed technology. This paper introduces the developed ICT and presents the potential of the ICT as a new environmentally friendly alternative technology in the field of concrete cutting and dismantling using a diamond wire saw through a comprehensive analysis of various verification experiments.
Two bridge structure specimens were prepared for this verification test, and the verification using the testbed was judged to be sufficient for the comparison with the DCM related to the remaining dust treatment capacity. Thus, it was determined to compare the WCCM and the ICT developed in this study for the field application test. Focusing on whether the ICT can replace the WCCM, which directly sprays water as a means of reducing the high friction heat generated in the concrete cutting process, this study measured the maximum temperature in the cutting process and the cutting time, which is related to the cutting performance.

제안 방법

After completing the testbed verification test, a verification test was performed for an actual bridge to examine the field applicability of the ICT. The bridge used in this experiment was a concrete structure with a cross-section of 0.
Thus, it was determined to compare the WCCM and the ICT developed in this study for the field application test. Focusing on whether the ICT can replace the WCCM, which directly sprays water as a means of reducing the high friction heat generated in the concrete cutting process, this study measured the maximum temperature in the cutting process and the cutting time, which is related to the cutting performance. The field application test and the results are shown in Fig.
Given this background, this study developed an innovative cutting technology (ICT) that solves both the concrete waste sludge problem of the WCCMs and the dust treatment problem of the DCM^[4,5]. Furthermore, two testbed verification experiments and a field application verification experiment for a full-scale concrete bridge were carried out for the developed technology.
In this study, a new diamond wire saw cutting method (ICT) that can be used for large structures was introduced and experimentally verified. The conventional WCCMs cause environmental pollution by generating concrete waste sludge, and the DCM causes air and water pollution due to the remaining dust on the cut surface.
To compare the dust treatment efficiency of the conventional DCM and the ICT applying a rotating air sprayer, the amount of concrete dust collected in the vacuum dust collector and the amount of dust remaining on the cut surface when the specimen was cut in each method were measured. Table 4 lists the amounts of dust generated by type.
The biggest environmental problem of the WCCMs, which uses water to cool down the heat generated from the cut surface when a structure is cut with a wire saw, is the treatment of waste sludge generated by the mixing of ground dust and water. To solve this problem, this study devised a system that cools down the wire saw by using a separate cooling device outside the cut surface instead of the conventional cooling method that directly applies water to the cut surface. Fig.
9. Two bridge structure specimens were prepared for this verification test, and the verification using the testbed was judged to be sufficient for the comparison with the DCM related to the remaining dust treatment capacity. Thus, it was determined to compare the WCCM and the ICT developed in this study for the field application test.

대상 데이터

The bridge used in this experiment was a concrete structure with a cross-section of 0.7 m×0.7 m, and its shapes before and after the verification test are shown in Fig. 9.

성능/효과

However, unlike the WCCM, the ICT generated no waste sludge, because it does not use cooling water. In the maximum temperature measurement test conducted to examine the cooling performance, which was the second measure of performance evaluation, the ICT and WCCM showed similar temperatures, but compared to the DCM, the temperature of the ICT was lower by approximately 70℃ on average, indicating a significant improvement effect. Finally, regarding the remaining dust treatment capacity, the ICT showed a significant improvement effect by reducing the amount of dust to approximately two-thirds compared to the DCM.
92 min/m³ for all three cutting methods performed twice each. When compared to the DCM, the proposed ICT showed a cutting performance improvement effect of approximately 17%, which is relatively large, but when compared to the WCCM, the cutting speed of the ICT was approximately 7% slower, which is not a large effect. This appears to be because the WCCM performs the cooling and washing relatively efficiently by directly spraying water on the cut surface.

후속연구

The actual bridge cutting test performed for the field application confirmed that the proposed ICT showed an improvement effect similar to that of the testbed verification test. Therefore, this study confirmed the possibility of using the ICT as a new environmentally friendly replacement technology in the field of concrete cutting and dismantling using a diamond wire saw.
