On the other hand, the conduction test for conduit construction completion inspection is carried out twice. At this time, the first conduction test is carried out before the first backflow and the second conduction test is carried out before the road packaging.

하지만, 포설 시공 후 상당 기간이 지난 후에 관로 안으로 전력 케이블을 입선하기 때문에 지반 침하나 지반 변동으로 인해 관로의 변형이 발생된다.

따라서, 관로 안으로 전력 케이블을 입선시킬 때 많은 어려움이 있었다.
Therefore, there was a great deal of difficulty in picking up the power cable into the pipeline.
