Detailed description of the invention
Embodiment 1: as shown in Fig. 1 ~ Fig. 4, the present embodiment comprises steel pipe type major diameter single pile 1 and is arranged in the ice resistant structure in its outside, ice resistant structure need cover the elevation scope (H) of sea ice effect, and ice resistant structure is arranged to upper and lower two circles, and each position relative level face is mirror image and installs a pair of.In this example, ice resistant structure comprises short horizontal stay tube 2, long horizontal stay tube 3, outside inclined tube 4 and flange 5, short horizontal stay tube 2 is arranged in parallel up and down with long horizontal stay tube 3, two horizontal stay tube medial extremitys are all shaped with flange 5, the outboard end of two horizontal stay tubes is welded and fixed outside inclined tube 4 jointly, between long horizontal stay tube 3 and outside inclined tube 4, welds down tube 6.Outside inclined tube 4 is in tilted layout, and is certain slope angle with steel pipe type major diameter single pile 1, and the outside inclined tube 4 of upper and lower two circle ice resistant structures forms the anti-ice cone contacting with sea ice.Ice resistant structure is connected with the connector in steel pipe type major diameter single pile 1 main body by flange 5.
The present embodiment, in work progress, first carries out the pile sinking of steel pipe type major diameter single pile 1, then by flange 5 mode with bolts, ice resistant structure is connected with steel pipe type major diameter single pile 1.
Embodiment 2: as shown in Fig. 5 ~ Fig. 8, the present embodiment structure is substantially the same manner as Example 1, difference is only that in this example, ice resistant structure is made up of short horizontal stay tube 2, long horizontal stay tube 3, waling stripe 7, stay pipe 8, outside inclined tube 4 and flange 5, and wherein two outside inclined tubes 4 and a waling stripe 7 are welded into triangle inclined tube assembly; Short horizontal stay tube 2 is arranged in parallel up and down with long horizontal stay tube 3, between short horizontal stay tube 2 and long horizontal stay tube 3, is welded with down tube 6.Short horizontal stay tube 2 is all shaped with flange 5 with long horizontal stay tube 3 medial extremitys, long horizontal stay tube 3 outboard ends connect in triangle inclined tube assembly near two outside inclined tube 4 angled end by stay pipe 8, (triangle inclined tube assembly is in tilted layout short horizontal stay tube 2 outboard ends connect the link of two outside inclined tubes 4 and waling stripe 7 in triangle inclined tube assembly by stay pipe 8 near, be certain slope angle with steel pipe type major diameter single pile 1, the triangle inclined tube assembly of upper and lower two circle ice resistant structures forms the anti-ice centrum contacting with sea ice).Ice resistant structure is connected with the connector in steel pipe type major diameter single pile 1 main body by flange 5.
Embodiment 3: as shown in Figure 9, the present embodiment structure is substantially the same manner as Example 2, difference is only in the present embodiment region division steel plate 9 between two outside inclined tubes 4 of triangle inclined tube assembly, contributes to sea ice to fracture along climbing of ice resistant structure outer slope region.In this example, waling stripe 7 plays the effect of inner side floor, supplemental support steel plate 8, and the number of waling stripe 7 arranges as required.
Embodiment 4: shown in Figure 10, for embodiment 2 or example 3, due to two outside inclined tubes 4 at an angle, for having certain space between adjacent two anti-ices structure of single pile hoop, meet with in sea ice situation, these spaces may " be filled up " by sea ice, to structure bear ice carry unfavorable, for reduce this space as far as possible, can consider embodiment 1 and embodiment 2 or example 3 to be combined into the pattern of alternating expression.
Embodiment 5: shown in Figure 11, also with by embodiment 2(or example 3) certainly combine the pattern of alternating expression.Wherein, the angle of outside anti-ice structure is all that upper and lower two anti-ices structure near-end is gradually slow to far-end angle, ensures that upper and lower two groups of anti-ices structure is tapered.Concrete which kind of embodiment pattern that uses, according to the ice condition synthetic determination in sea ice of living in region.
In addition, the ice resistant structure in the present invention is connected except the member by adopting bolt-type flange or other connected mode with steel pipe type major diameter single pile 1, because these syndetons are all ripe, conventional structures, no longer launches explanation herein.
