Problems solved by technology

Therefore, for large-scale reclamation projects with a project volume of hundreds of millions of cubic meters and a transport distance of hundreds of nautical miles, it is impossible to improve dredging efficiency and reduce dredging unit price only by relying on the large-scale effect of self-propelled trailing suction dredgers the goal of
Because the self-propelled trailing suction dredger, which integrates functions such as digging, transporting, throwing, and blowing, uses its expensive dredging equipment for a very small proportion of dredging operations in the entire operation cycle, and most of the time has to be dredged like The long-distance transportation of sediment like a bulk carrier makes its most important dredging function unable to be fully utilized

Embodiment Construction

[0010] Double-hull trailing suction dredger without mud tank (see figure 1 , figure 2 ) adopts the bow connecting bridge and its superstructure 1, the midship connecting frame, and the stern connecting frame 3, and connects two hulls with a large separation distance into a rigid connection through a longitudinal beam structure.

[0011] The bulbous bow improves sailing performance. The bow is provided with a side thruster 10 to improve the dynamic positioning capability and help the mud barge to enter and exit the double body room. The propulsion devices are located at the rear of the two hulls, and the tail propeller 7 adopts a variable pitch propeller to enhance the maneuverability of the ship and facilitate the safe entry and exit of mud barges. The stern adopts a diversion skeg stern design, and the stern of both hulls has a skeg, which can enhance the structural strength of the stern, facilitate the mud barge to enter and exit the double hull, and protect the propeller...

Abstract

The invention provides a non-mudhold double-body drag suction dredger and a construction method thereof and relates to dredging equipment and a construction method thereof. The technical scheme is that: the drag suction dredger equipped with a propelling device, drag suction dredging systems, a boat-loading system, deck machinery and a mud boat binding device is used for dredging and taking sand.The invention is characterized in that: the drag suction dredger is a non-mudhold double-body drag suction dredger; the dug sand is loaded into a selfpropelled mud boat anchored between two boat bodies of the drag suction dredger through the boat-loading system arranged on decks of the boat bodies on the two sides; and after being loaded, the mud boats are conveyed to the dredge filling position in a selfpropelled mode. The non-mudhold double-body drag suction dredger and the construction method thereof can be applied to large-scale dredge filling projects and sand-taking projects in abyssal regions far away from coasts.

Description

technical field [0001] The invention relates to dredging equipment and a construction method for a large-scale reclamation project with a super-long transport distance. Background technique [0002] Land reclamation is an important marine engineering in human ocean development activities, and an important means for human beings to expand living space and production space to the ocean. As the global demand for land resources continues to increase, land reclamation projects are being carried out all over the world. Since the modern self-propelled trailing suction dredger integrates the functions of digging, transporting, throwing and blowing, it has long been the main dredging equipment in the formation of large coastal land areas. In order to meet the needs of large-scale dredging and reclamation projects, self-propelled trailing suction dredgers continue to be large-scaled. However, the cost of super-large self-propelled trailing suction dredger is very expensive, and the ...
