3Dアズビルドレーザ計測を利用したライニング配管の製作・据付精度向上
概要
Due to the high degree of required dimensional accuracy in its manufacturing, repairing of lining pipes with flanges requires a long installation period. With the conventional method, we have to wait more than three weeks to start lining installation after the start of onsite construction, because pipe dimensions are determined onsite then lining installation is conducted at shop. It causes prolongation of the onsite installation period. Therefore, we have tried to improve the dimensional accuracy in its manufacturing by applying three-dimensional as-built laser measurement device which enables high precision measurement. In addition, we established a new process from manufacturing to installation. As a result, we achieved successful shortening of onsite lining pipe repairing period. However, there are still some conditions and points to be dealt with to apply this method to the actual construction. We organize them and provide important points in this paper.
