摘要

PURPOSE: A long span bridge structure construction method using a bridge deck of a land section and a barge is provided to rapidly and conveniently install a long span bridge to reduce the construction period by transporting the bridge deck by a barge after the bridge structure is installed on the bridge deck.;CONSTITUTION: A long span bridge structure(20) construction method using a bridge deck(10) of a land section and a barge(70a) is composed of the following steps: The bridge deck with piers(11) is installed on both sides of a water section(A) and the lower part of a land section(B) of a bridge and equipped with a first and second rails(31,60) on the upper part of the left side of the bridge deck.

The lifting unit is lifted after the bridge bearing of the left side of the bridge structure is moved to the right side. The barge is moved to the left side of the bridge deck to place the left side of the lower side of the bridge structure and then move to the right side of the bridge deck. The bridge structure is moved from the left side to the right side and installed on the right side by the transport unit or the barge provided on the lower part of the bridge structure.
