s4, after coarse centering is finished, sleeving two boring bar supporting bearings into two ends of a boring bar respectively, and fixing the two supporting bearings on a ship body or other stable structures;
s5, accurately adjusting the center line of the boring bar to a theoretical state by using an adjusting bolt on a support bearing;
s6, boring;
s7, removing the boring bar positioning adjustment tool;
s8, inserting the dummy shaft on the anti-rotation pin positioning tool into a central hole of the cup-shaped pipe joint from one side of the large head end of the cup-shaped pipe joint, and keeping each shaft sleeve of the anti-rotation pin mounting and positioning tool below an anti-rotation pin mounting screw hole in the outer wall of the cup-shaped pipe joint;
s9, an anti-rotation pin is preliminarily installed on the outer side wall of the cup-shaped pipe joint through an anti-rotation pin installation bolt, a base of the anti-rotation pin positioning tool is rotated, the anti-rotation pin is inserted into each shaft sleeve on the anti-rotation pin positioning tool, the insertion condition of the anti-rotation pin and the shaft sleeves is checked, the thickness of an adjusting washer required to be arranged between the anti-rotation pin and the cup-shaped pipe joint is configured according to the insertion condition, and finally all the anti-rotation pins are inserted into each shaft sleeve on the anti-rotation pin positioning tool.
8. A disposable ballast mounting method as set forth in claim 7, wherein S1 is that the centers of the cup type coupling and the beam hole are checked by the suspension wire method, the allowance for machining, the horizontal deviation, and the positioning deviation of the center line from the theoretical center line are checked and adjusted, and after the check is correct, the cup type coupling and the beam hole are marked by the sample plate.
9. A disposable ballast mounting method as set forth in claim 8, wherein S2 is such that the upper positioning regulator is detachably fixed to the screw hole of the cup type coupling and the lower positioning regulator is detachably fixed to the anti-rotation pin mounting screw hole of the outer side wall of the large end of the cup type coupling.
10. A method of installing a disposable ballast as claimed in claim 9, wherein in S3, a hand block is used to hoist the boring bar through the cup-shaped pipe sections and the load beam.
