Load-carrying ability analysis about this pile-driving barge
This pile-driving barge is compared with pile-driving barge at present commonly used to have increased and is hung a loop wheel machine, deposits a support and change the stake device, also has 5 piles 9 in addition, and can about 500t that gain in weight altogether, pile-driving barge commonly used bear the 500t weight of increase, now do following analysis.
(1) No. 2 about 2600t of pile-driving barge load-carrying ability of stake, No. 2 deadweights of stake (comprising fresh water and diesel oil) about 1600t, the about 1000t of ballast water.The effect of ballast water has 2 points on the pile-driving barge, and the one, in order to reduce the pile-driving barge center of gravity, increase the stability of pile-driving barge, the 2nd, by regulating hull separately the water yield in four setting-out cabins all around, make pile-driving barge keep horizontality.The effect of ballasting is played in the 500t deadweight of newly added equipment and stake equally, so as long as the 1000t ballast water is reduced to 500t, this has just solved the influence of the deadweight of newly added equipment to piling boat-carrying Beijing South Maxpower Technology Co. Ltd power.
Mountain, ocean pile-driving barge ballast water is 1960t, so the deadweight of newly added equipment does not more have influence to foreign mountain pile-driving barge load-carrying ability.
(2) analysis that the newly added equipment asymmetric arrangement is horizontal to pile-driving barge, the vertical equity degree influences
Be that example is analyzed with No. 2 pile-driving barges of stake still, the weight of symmetric arrangement is 240t in the newly-increased 500t equipment, and the weight of asymmetric arrangement is 260t.500t ballast water weight is greater than the 260t weight of asymmetric arrangement, utilizes the 500t ballast water at pile-driving barge regulating pondage in four setting-out cabins all around, can make pile-driving barge keep horizontal, vertical equity.
(3) the initial stability value of public technology pile-driving barge is more much bigger than the initial stability value of " Rules for the Stability of Sea-going Ships " and " inland navigation craft stability standard " middle regulation, the stability that pile-driving barge is described is good, this pile-driving barge is because of having increased by three equipment, the center of gravity of boats and ships is slightly raised, but its initial stability value still may be bigger than the initial stability value of regulation; Hull of the present invention in addition can suitably be adjusted hull principal dimension and pressur loading weight in design process, make initial stability value greater than the initial stability value of stipulating in " Rules for the Stability of Sea-going Ships " and " inland navigation craft stability standard ", so the stability problem of this pile-driving barge should be soluble with the pile-driving barge that changes the stake device.
