Barge with bonded hull and dredging method using barge

摘要

The present invention relates to a barge with a coupling type hull, which comprises a hull unit, first and second coupled hull units, a vertical coupling unit, and a horizontal coupling unit, improves convenience and workability in manufacturing and land transportation due to a plurality of hull coupling structures, contributes to increase of durability after coupling among the hulls due to a complex coupling type by horizontal and vertical coupling structures, and improves stability and reliability for work on water surface thereby. Moreover, the hull is able to be lifted from a ground surface, thereby providing convenience in transportation not to require separate equipment in loading on a vehicle and the like. Moreover, a long boom is mounted on the upper part of the hull unit, such that accessibility to a place incapable of being accessed due to a problem, such as a river, a reservoir, or the depth of water, thereby providing an advantage of facilitating dredging. According to the present invention, the dredging method comprises a preparation step, a coupling step, a pile installation step, a long boon loading step, a barge moving step, a dredging position depth checking step, a dredging position occupying step, a dredged soil transfer step, a separation step, and a loading step.
