Description
Technical Field
The application belongs to the technical field of ship body protection, and particularly relates to an anti-scouring structure and an anti-scouring method for a ship bottom.
Background
The ship sits at the bottom means that: the submersible ship can be submerged and completely landed on the seabed to carry out offshore operation, namely, the ship is actively and safely grounded. With the continuous development of ocean resources and the demand of ocean engineering construction, more and more ships need to have the function of sitting on the bottom. The adsorption force (including adhesive force and negative interstitial water pressure) generated between the ship and the viscous substrate soil after the ship sits on the bottom (especially for a long time) is a key factor influencing the ship from the bottom. At present, after a ship sits on the bottom, the water flow at the contact position of the bottom of the ship and the sea bottom surface changes under the action of the water flow, so that the mud surface is scoured, and the ship slides or is broken. The currently applied inserting plate type structure is generally a steel structure, and the steel structure is inserted into a mud surface along a ship side during application, so that scouring is prevented.
At present, because the steel inserting plate has high structural strength, if the inserting plate is inserted into a mud surface, a ship sideslips, and because the inserting plate has high structural strength, an inserting plate structure or a slideway structure of the inserting plate structure can deform, and a contact part of the structure and the ship can damage the ship, thereby causing accidents.

This clearance can be so that the scour prevention effect of scour prevention structure is better to when boats and ships sideslip, the picture peg is more difficult to strike the hull, causes the hull damage.
As shown in fig. 1 and 2, in the anti-scour structure for the ship bottom, the slide ways are multiple and are arranged on the side of the ship side by side;
the number of the inserting plates arranged in the slide way is also multiple.
The second embodiment of the present application provides an anti-scouring method for a ship bottom, which includes:
mounting a prefabricated anti-scouring structure for the bottom of the ship on a ship board of the ship;
when the ship reaches a designated construction operation area, selecting a proper bottom-setting position for submerging and setting;
and placing the inserting plate on the top of the ship, and after the ship submerges and sits at the bottom, placing the inserting plate to a preset position through a slideway by a winch until the inserting plate is completely placed.
When boats and ships sit the end, the scour prevention structure can play the scour prevention effect, and semi-rigid part is located the below of rigid second part, if boats and ships take place to sideslip, and its semi-rigid second part can take place to warp, and adaptation boats and ships slide to can not cause the hull to destroy.
After the ship construction operation is completed, the inserting plate needs to be retracted in advance, and the inserting plate is slowly pulled up by the winch in the retracting process, so that the inserting plate is prevented from influencing the stop of the ship side on the side of the port and the starboard.
As shown in fig. 1 and fig. 2, the present application further provides a ship, including the above-mentioned anti-erosion structure 1 for ship bottom, where the anti-erosion structure 1 is multiple and symmetrically disposed on the side 100 of the ship. Specifically, as shown in fig. 8, the ship board 100 located at the stern is provided with the erosion prevention structure 1 at both sides thereof. Of course, under different ship bottom-sitting working conditions, a plurality of anti-scouring structures need to be arranged, and the anti-scouring structures can also be arranged on two sides of a ship board at the stern. A plurality of scour prevention structures are located boats and ships different positions, and when the environment all around of boats and ships differed, different scour prevention structures can be transferred to different positions to different all around different ship environments of adaptation.
