The specific embodiment

Referring to Fig. 1-Fig. 5, the present invention plans to build heavy sea crane base and is positioned at hull afterbody, and hoisting crane own wt is 4000 tons.During stern fixed mode, radius of turn is 43m, and load-carrying ability is 4000 tons; During full circle swinging pattern, radius of turn 33m, load-carrying ability is 3500 tons.

Planning to build hoist base is that diameter is the cylinder type of 24.3m, and it is highly 13.40m, and cylindrical shell top is that wall thickness is that 45mm material is the steel plate of EH36-Z35, and bottom is the steel plate that thickness of slab 30mm and 45mm material are EH36.Cylinder body bottom is welded on the platform 14 of baseline 9100mm, and the barrel wall that 2.2m is high is still arranged on A deck 2 at its top.

Due to 813.20 tons of hoist base structure gross weights of the present invention, when dock carries, safe load-carrying ability can reach 700 tons, for guaranteeing safe construction, the base of cylinder type must be carried out to sectional construction, this segmentation should guarantee precision, guarantees that again the intensity of cylinder self is unaffected, also will consider technique and lifting while building.It is the main and normal mode combining of building that the build process of whole cylinder type base of the present invention has been defined as counter making.

Understructure of the present invention is as depicted in figs. 1 and 2: base radius of turn is 33m, and take main deck 1 and A deck 2 is the end, is divided into three layers.Every one deck is equipped with deck base plate 3 in its bottom, the equidistant reinforced rib 4 that is provided with on deck base plate 3, and be equipped with crossbeam 5 at the horizontal direction of deck base plate 3, on crossbeam 5, vertically weld transcerse bulkhead 6; Longitudinal direction at deck base plate 3 is laid longeron 7, is vertically welded with longitudinal bulkhead 8 on longeron 7.

Outer at above-mentioned base radius is established stiffener 9 straight up, and at stiffener upper berth barrel plate 10, at base top hoop, has ring stiffener 11.

For main deck 1 can connect, on the cylinder type base on main deck 1 top, have bottom, arch ,Gong hole, hole and lay one deck pipe laying slideway 13.

During fabrication, two schemes are proposed:

The first scheme, as shown in Figure 3: by cylindrical shell segmentation by carrying out up and down segmentation division, from 9100mm A/B platform deck to 14000mm A/B(main deck 1) be segment section, be designated as 301B section; From 14000mm A/B main deck to 20300mmA/B(A deck 2) be segment section, be designated as 301A section.Part more than 301A section is TUB section, and TUB section is also as an independently segmentation, and it is built after closing up in 301A, the lift-launch of 301B section dock, sees Fig. 3.Another pipe laying slideway structure, also as a segmentation, is finally built.

The advantage of this scheme is that 301A section is done as a whole construction, and precision is controlled can be better, and in addition, its height dimension drops to 6.3m, and handling and sectional turn-over are convenient.Shortcoming is that vertical stiffener 9 has been disconnected at segmentation seam place.

Alternative plan, as shown in Figure 4: tube structure is carried out to segmentation division by left and right, from 9100mmA/B platform deck to 20300mm A/B(A deck 2) tube structure be divided into left and right 2 segmentations, dividing range is the 200mm place apart from hull center line face at larboard, larboard one side is 301C section, and starboard one side is 301D section.The TUB section of more than 2 part in A deck is identical with the first scheme.

This scheme advantage is that vertical stiffener 9 does not disconnect, and shortcoming is handling subsection, stand up and increased difficulty.

One of above two scheme are that upper and lower segmentation, one are left and right segmentations, and it has limitation, and impact is built.Finally, the first two scheme is merged, compromise and the 3rd scheme, as shown in Figure 5:

Be mainly base in the segmentation of carrying out with A deck 2 and 1 two basal planes of main deck, its division step is as follows:

By the lower segment section 301B section of the 14000mmA/B main deck of the tube structure shown in Fig. 31 to 9100A/B platform deck, be divided into 2 segmentations in left and right, its dividing range is at larboard apart from hull center line face 200mm place, and larboard one side is 301BC section, and starboard one side is 301BD section.

By the 14000mmA/B of the tube structure shown in Fig. 3 (main deck 1) to 20300mmA/B(A deck 2) upper segment section 301A section, be divided into equally 2 segmentations in left and right, its dividing range is at larboard apart from hull center line face 200mm place, and larboard one side is 301AC section, and starboard one side is 301AD section.

301AC section and the part above 301AD section, 20300mmA/B(A deck 2) above part is as a TUB section independently, no longer divides.

This scheme can be take 4 segmentations respectively the main deck 1 of 14000mm and the A deck 2 of 20300mm as basal plane construction, then two of the left side sections of 301BC sections and 301AC are first assembled, utilize the vertical stiffener structure of hoist base self as template barrel plate 9 in bulk, after standing up, be lifted on hull platform, then two of assembled the right segmentation 301BD sections and 301AD section, after standing up, be lifted on hull platform, then left and right two parts are merged as cylindric; Finally, on the cylindric base of moulding, take A deck 2 as bottom, accurately locate vertical stiffener, take vertical stiffener as template TUB segmentation in bulk barrel plate, complete TUB section and build.

This segmentation method had both solved builds choosing of basal plane, saved the material of extra template, guarantee the intensity of base, solved again the difficult problem of standing up difficulty, lifting difficulty, easily causing the distortion of base out of roundness, effectively realized the accurate construction of manufacturing the segmentation of goliath base.
