Problems solved by technology

[0004] Although the traditional small cutter suction ship has the advantages of shallow draft, small main scale, and can meet the requirements of land transportation after disassembly and assembly, but the production capacity is weak, the digging width is small, and the row spacing is short
Can not meet the needs of modern engineering
If we want to increase the production capacity and increase the excavation width, the main size of the hull will inevitably be increased, and it cannot meet the requirements of shallow draft or disassembly and transportation.
In addition, most of the equipment used on board is driven by hydraulic pressure, which is inefficient
Hydraulic oil leakage will cause environmental pollution and fail to meet environmental protection requirements

Embodiment Construction

[0024] The present invention will be explained in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 A combined dredger according to an embodiment of the present invention shown in , includes a bow 1 , a combined middle 2 and a stern 3 which are sequentially articulated. In the embodiment of the present invention, the detachable connection is preferably a hinge, and of course it may also be a detachable connection in other ways, which is not limited in this embodiment.

[0026] The combined middle part 2 includes several components 21, and the combined middle part 2 is hinged by several components 21 sequentially.

[0027] In the embodiment of the present invention, the bow and the stern of the hull are directly combined to form a complete dredger in engineering construction without a large dredging width.

[0028] The embodiment of the present invention adopts a detachably connected hull, which can not only ensure the shallow draft of the ...

Abstract

The invention provides a combined-type dredge ship. The combined-type dredge ship comprises a bow part and a stern part which are connected with each other; the bow part is connected with the stern part in a detachable manner. According to the technical scheme disclosed by the invention, a ship body adopting the detachable connection and electrical drive are adopted, so as to improve defects in traditional small-sized cutter suction dredgers; shallow draft of the ship body can be ensured, and the overall strength of the ship body can be ensured; therefore, the maximum digging width is greatly increased, so that dredging in a coastal zone and shallow tidal flats of inland rivers becomes more efficient, energy- saving, environment friendly and economical.

Description

technical field [0001] The invention belongs to the field of shipbuilding, and relates to a dredger, in particular to a combined dredger. Background technique [0002] At present, the cutter suction dredger is the main construction ship for dredging projects. With the characteristics of wide application and high construction efficiency, it has become the main ship type in various dredging projects all over the world. [0003] In recent years, coastal cities have attached great importance to the comprehensive management of coastlines, and have taken the improvement of a large number of coastal zones as the focus of future urban planning and construction. Sea land reclamation and shallow water dredging of coastal zones will be the main project content of coastal zone consolidation . Among them, the environment of shallow tidal flats is comprehensively improved, and the dredged soil is mainly treated by cutter suction dredger blowing and reclamation. This type of project req...
