The gouging abrasion etc. of through-hole 13；And landing slab main rib 15 protrudes upward, can play baffle effect, when stopping staff's operation
Tool falls to the bottom of the shell of spud leg section from pipeline receiving opening 13.Multiple landing slabs time rib 16 is arranged in dispersion shape
In landing slab 101, increase the integral strength of landing slab 101, and the middle part stress concentration for being effectively prevented from landing slab 101 is asked
Topic, makes the even intensity of landing slab 101 everywhere.
Multiple coaming plate fixing ribs 21 can be set, and longitudinally interval is uniformly distributed in the inside of the coaming plate 2, the coaming plate
Fixing rib 21 plays the role of enhancing 2 intensity of coaming plate.Accordingly, multiple coaming plate installation grooves 14 can be set, and the coaming plate is fixed
Rib 21 is connected in coaming plate installation groove 14, to increase the contact area between coaming plate 2 and platform partition board 1, convenient for welding, makes to enclose
Plate 2 is more securely mounted at platform partition board 1, avoids 2 stress concentration of coaming plate at one, stress is more uniformly distributed.
Preferably, the coaming plate fixing rib 21 is bar shaped rib, and accordingly the coaming plate installation groove 14 is bar-shaped trough, is both risen
To the effect of enhancing 2 intensity of coaming plate, and convenient for assembled welding.Alternatively, the coaming plate fixing rib 21 is T-type rib, it is accordingly described
Coaming plate installation groove 14 is T-slot, and T-type structure can increase the contact area between coaming plate 2 and platform partition board 1, greatly improve
The intensity of coaming plate 2.
Preferably, as shown in figure 4, the coaming plate installation groove 14 passes through the landing slab time rib 16 and landing slab main rib 15
Connection；Spacing of the two neighboring landing slab time rib 16 in one end towards landing slab main rib 15 is more than towards coaming plate installation groove 14
The other end spacing.Coaming plate installation groove 14 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, to make coaming plate fixing rib 21, landing slab time rib 16 and landing slab master
Rib 15 is connected, and the integral strength of high intensity octagon spud leg section is significantly enhanced, stress is made more to disperse.Since coaming plate is fixed
The coaming plate installation groove 14 of position horizontal edge 11 is distributed the length for being smaller than 15 corresponding sides of landing slab main rib, in order to make intensity point
Cloth is uniform, and spacing of the two neighboring landing slab time rib 16 in one end towards landing slab main rib 15, which is more than towards coaming plate, to be installed
The spacing of the other end of groove 14, to avoid problem of stress concentration；Wherein each 11 end of coaming plate position level edge
