Laboratory Test of Molecular Vibration for Preventing Drainage Pipe Blockage in Deteriorated Tunnel

By ?????????

Abstract

Clogging of drainage pipes by scale is an important problem in civil engineering works. Although scale deposits can be removed by acid treatment or water jetting, these treatments are costly and have many disadvantages. In this study,scale samples from tunnel drainage pipes were analyzed using SEM-EDS and XRD. The main ingredient in scale was CaCO3 of the calcite crystal form. Drainage experiments and recirculation type experiments were conducted to control and remove scale deposits, which were determined through visual and weight measuring analysis. As a result, Quantum Stick has the effect of limiting formation of scale?????? ?????? ???????????? ??????????????? ?????? ????????? ??????????????? ?????? ??? ????????? ??? ????????? ???????????? ????????? ????????? ????????????. ????????? ?????? ?????????
