Or on ship, the bolt hole 4 on anti-ice standard component two ends arc connecting plate 1 is enclosed within the shank of bolt 7 of semicircle anchor ear 6 correspondence, and
Fix with nut 10, be finally assembling to semicircular structure and amount to two；
(2), intending mensuration, mark installment position on protection large diameter pile 12, two semicircular structures are waled, are enclosed within major diameter
The appointment position of stake 12, with bolt, the bolt hole 8 of fixing semicircle anchor ear 6 upper flange 9 of nut 11, fixing tightening i.e. completes peace
Dress.
The dismounting and change parts construction method of the detachable ice resistant device being applicable to marine large diameter pile is described below:
(1), unclamp, lay down fixing top and the bolt of lower semicircular shape anchor ear 6, nut 11, ice resistant structure is resolved into two
Semicircular structure, moves on ship；
(2), aboard ship, carry out dismantling, changing related accessory, anti-ice standard component can be changed, it is possible to change semicircle anchor ear 6；
(3), change and terminate after, according to original installation method, assemble and construct.
The present invention compared with prior art, has the advantage that anti-ice standard component is shape upper and lower, symmetrical, installation side
Just, steel using amount is few, can realize standardization, large-scale production；Being provided with two blades that open ice on anti-ice standard component, it makes sea ice hold
The most disrumpent feelings, open ice effective；The most on the coast or on ship, anti-ice standard component is assembled into semicircular structure with semicircle anchor ear, it is only necessary to
At sea assembling eight bolts i.e. to complete to install, Potential Working Time For Operation At Sea is short, efficiency is high；Dismounting is constructed simple with changing parts, behaviour
Facilitate.
