Technical Field
[0001] This invention relates to the field of barge technology, specifically to a self-propelled shallow-draft barge capable of laying road pavers. Background Technology
[0002] Traditional nearshore shallow water construction vessels mainly consist of hull-bottomed platforms or ships. They employ a method of ballasting the vessel at high tide, then discharging the ballast water after the operation is completed to allow it to float to a new location and repeat the process. Existing technologies have the following main drawbacks: 1) Existing vessels require a high draft when bottoming out, generally above 2-3 meters, which cannot meet the needs of operations in shallower drafts; 2) Existing vessels cannot be moved directly after they sit on the bottom. They can only be moved by discharging water to float up, and then pressurized with water to sit on the bottom again. The process is complicated and takes a lot of time.
[0003] Therefore, there is a need for a vessel that can adapt to shallow-draft operations and is easy to move after settling on the bottom, in order to meet the requirements of operating closer to the shore in shallow waters and moving quickly. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figure 1-2 This invention provides a technical solution: a self-propelled shallow-draft barge capable of laying road slabs. Its main hull is a welded steel structure with a longitudinal frame construction. The bottom plate and side plates are made of high-strength marine steel to enhance impact resistance and pressure bearing capacity when the hull is on the ground. The interior of the main hull is divided into an engine room 11, a steering gear room, a bow thruster compartment 10, and a main propulsion compartment 15 by watertight transverse bulkheads. Three diesel main engines are fixedly installed in the engine room 11 via welded bases. Generators and other auxiliary equipment are bolted to the bottom base. Various oil and water compartments are naturally separated by the hull structure, and the ballast water system piping runs through each ballast tank using flange connections. The steel pavement system is fixed to a reinforced base in the middle of the top of the main deck 1 using a group of high-strength bolts. Dense transverse and longitudinal trusses are added below the deck in this area to distribute concentrated loads. The pavement tractor 2 is a tracked structure, with its frame connected to the deck base using a composite connection of shear pins and pressure plates. The steel pavement storage compartment 3 is an open box-shaped welded structure, welded to the deck at the bottom, and equipped with multiple layers of guide rollers inside. The drum support of the pavement recovery module 4 is welded to the deck, and the drum shaft system is supported by self-aligning roller bearings and driven by a hydraulic motor through a gearbox. The three azimuth thrusters 16 in the main propulsion compartment 15 are connected to the outer plate of the bottom of the hull by flanges. The connection between the thrusters and the hull structure is reinforced with thickened plates. The thruster shaft system is connected to the output shaft of the main engine in the engine room 11 by a high-elasticity coupling. The drive shaft passes through the watertight bulkhead and is sealed with a stuffing box. The water jet-type lateral thrusters in the bow thruster compartment 10 are also installed by flanges. Their flow channels are integrally welded to the hull structure. The inlet grating is made of manganese steel. The stern anchor system consists of a stern anchor and anchor frame 14 welded to the stern of the main deck 1 and a winch seat. The stern anchor and anchor frame 14 are welded together from channel steel and web plate. The winch seat is continuously welded to the deck on both sides. The wire rope of the stern winch and wire rope 13 is led out overboard through the cast steel cable guide hole. The bow ramp 7 is a hinged steel structure. Its root is connected to the cast steel support at the bow of the hull through a high-strength pin. The two ends of the hydraulic cylinder are connected to the hull lugs and ramp lugs respectively through pins. Anti-slip strips are welded to the surface of the bow ramp 7. The bow deckhouse 6 is a welded steel plate enclosure structure, with its bottom continuously welded to the main deck 1 using fillet welds. The internal hydraulic pump station unit is installed on a base with vibration dampers. The transition ramp between the two deckhouses is a pressed steel plate structure, welded and fixed to the deck. The anchor winch base of the bow anchor system is welded to the deck reinforcement structure. The anchor chain cylinder of the navigation anchor 8 is a cast steel component, welded to the outer side plate and reinforced. The bottom of the main hull is equipped with a bottom reinforcement structure, including a locally thickened bottom plate and a denser bottom girder. The 17th log is a welded steel plate structure, which is welded to the bottom outer plate of the main propulsion compartment 15 and has internal reinforcing ribs. The superstructure and chimney 12 are steel enclosure structures, which are welded to the main deck 1. The window frame of the bridge is fixed with aluminum alloy material.
[0019] When operating in shallow water, the ballast water system is used to adjust the draft, allowing the reinforced hull to sit stably on the riverbed. The thrust provided by multiple azimuth thrusters 16 and bow thrusters is used to maintain the ship's position and make minor adjustments. When laying the road panel, the road panel tractor 2 uses a hydraulic clamping device to engage the front end of the road panel and pulls the panel along the pre-set track on the deck from the storage compartment 3 to the beach. During the retrieval operation, the drum is driven by hydraulics to wind the steel wire rope, dragging the panel back and guiding it into the storage compartment 3 for folding and storage. When the ship needs to move a short distance, the anchor cable can be raised and lowered by the stern winch to provide traction, which, together with the main thrusters, enables movement while sitting on the bottom.
