In landing slab 101, increase the bulk strength of landing slab 101, and be effectively prevented from asking for the middle part stress concentration of landing slab 101
Topic, makes the even intensity everywhere of landing slab 101.
Multiple coaming plate fixing ribs 21 can be set, and longitudinally interval is uniformly distributed in the inner side of the coaming plate 2, the coaming plate
Fixing rib 21 plays a part of to strengthen 2 intensity of coaming plate.Accordingly, multiple coaming plates can be set groove 14 is installed, the coaming plate is fixed
Rib 21 is connected in coaming plate and installs groove 14, so as to increase the contact area between coaming plate 2 and platform dividing plate 1, is easy to welding, makes to enclose
Plate 2 is more securely mounted at platform dividing plate 1, it is to avoid at one, stress is more uniformly distributed 2 stress concentration of coaming plate.
Preferably, the coaming plate fixing rib 21 is bar shaped rib, and it is bar-shaped trough that accordingly the coaming plate installs groove 14, is both risen
To the effect for strengthening 2 intensity of coaming plate, it is easy to assembled welding again.Or, the coaming plate fixing rib 21 is T-shaped rib, accordingly described
Coaming plate installs groove 14 for T-slot, and T-type structure can increase the contact area between coaming plate 2 and platform dividing plate 1, greatly improve
The intensity of coaming plate 2.
Preferably, as shown in figure 4, the coaming plate installs groove 14 by the landing slab time rib 16 and landing slab main rib 15
Connection；Two neighboring landing slab time rib 16 installs groove 14 more than towards coaming plate in the spacing towards one end of landing slab main rib 15
The other end spacing.Coaming plate is installed groove 14 and is connected by the landing slab time rib 16 and landing slab main rib 15, the platform
Plate time rib 16 can be integrally welded with coaming plate fixing rib 21, so that coaming plate fixing rib 21, landing slab time rib 16 and landing slab master
Rib 15 is connected, and the bulk strength of high intensity octagon spud leg section is significantly enhanced, stress is more disperseed.As coaming plate is determined
The coaming plate of position horizontal edge 11 installs the length that the distribution of groove 14 is smaller than 15 corresponding sides of landing slab main rib, in order that intensity point
Cloth is uniform, and the two neighboring landing slab time rib 16 is in the spacing towards one end of landing slab main rib 15 more than installing towards coaming plate
The spacing of the other end of groove 14, so as to avoid problem of stress concentration；Described in each of which, coaming plate position level edge 11 is last
The coaming plate at end installs groove 14 by landing slab time rib 16 and the connection of 15 corresponding corner side of landing slab main rib, landing slab herein
Secondary rib 16 is inclined, can strengthen buckling strength.
Preferably, as shown in figure 3, the pipeline receiving opening 13 is square opening, accordingly, the landing slab main rib 15 is
Square rib；The other end of the landing slab time rib 16 is in hook-shaped shape；As shown in figure 4, the thickness of the guide plate 3 is more than coaming plate 2
Thickness.The pipeline receiving opening 13 is square opening, is compared with circular port, and the pipeline receiving opening 13 being square can be greatly
Improve receiving space；Accordingly, the landing slab main rib 15 is square rib, makes landing slab main rib 15 and pipeline receiving opening 13 more
For laminating, the intensity at the edge of reinforced pipe road receiving opening 13.As actually used middle coaming plate 2 can be subject to high wind, sea laps
Deng impact, the stress that the stress ratio platform dividing plate 1 that coaming plate 2 is subject to is subject to is much greater, thus landing slab time rib 16 and coaming plate
The other end of the connection of fixing rib 21 is in hook-shaped shape so that the other end of landing slab time rib 16 is compared with the one end of its own and wants high by one
