Description

Barge with bonded hull Barge with bonded hull

The present invention relates to a barge having a bonded hull, and more particularly to a barge having a hull, and more particularly to a barge having a hull, a first hull, a second hull, a vertical joining portion and a horizontal joining portion, To a barge having a joining hull which improves convenience and operational efficiency and which facilitates the dredging of a long boom at the upper part of the hull and is excellent in accessibility to a place where access to the heavy equipment due to the problems of rivers or reservoirs or water depths is impossible .

Generally, a barge or dredger is a barge that does not have a power unit that transports cargo at relatively short distances, such as in a harbor or an estuary, and may carry cargo, equipment, equipment, and large quantities of construction materials or construction equipment maritime On the contrary, it carries the cargo from the main line to the pier, and it is configured to sail by dragging or pushing to the tugboat.

However, when a conventional barge or dredger is manufactured to have a relatively large size for transporting a heavy object such as a longboom or a work using the same, it is not only difficult to produce but also has difficulty in land transportation. It has adopted a method of assembling a plurality of hulls to solve the problem.

A proposed prefabricated barge line (Korean Patent Laid-Open Publication No. 10-2016-0034705 (May 2013.030)) of the above-described assembling method includes a plurality of hexahedral unit hulls; An upper connecting member formed on the opposite side surfaces of the unit hull to connect adjacent unit hulls by mutual engagement; And front and rear connecting members formed on the front and rear surfaces of the unit hull and connecting the unit hulls adjacent to each other.

However, the above-described conventional technique causes a lot of inconveniences in assembling and disassembling due to a large number of bolts or the like for assembling, and most of the bonding strength is limited only by bolting, thereby limiting the durability of the combined state. It is disadvantageous in that the transportation work is inconvenient.
