The specification size and the quantity of floating gasbag are decided by calculating.If the deadweight of member is G, the buoyancy of self is F
Member, then help buoyancy F
Air bag=G-F
Member, because the proportion of water is 1.0, so the cumulative volume V=F of required floating gasbag
Air bag/ g=(G-F
Member)/g according to the volume of every air bag, can calculate required air bag quantity.The size of air bag is decided according to the size and the shape of member.
As shown in Figure 2, during (or about) runs through before and after member 6 has cavity, can be installed in air bag 9 in the member cavities, such as box culvert;
As shown in Figure 3, when the unmatched back of member (about) cavity that runs through or during for real chamber, can be contained in both sides, member front and back (or about) to floating gasbag 9 usefulness bundling belts 10, such as caisson, square, relieving slab, large cylinder etc., for ease of haul, generally be installed in the left and right sides of member.
(3) put on the slope and scoop out air bag: as shown in Figure 4, scoop out air bag 4 by land the setting of design attitude.For the air bag that scoops out under water,, must adopt fixing method in order to prevent the drift of air bag under current, wave and air bag self buoyancy.One of method is as Fig. 8,9, with the rope made of hemp 5 fixing air bags 4 under water, and when sliding under water the air bag top under the member, the airbag aeration rope made of hemp 5 (as Fig. 9) that rises brokenly under water, air bag promptly can roll downwards with member;
(4) member on the slope by land to moving down in the water: shown in Fig. 5,6,7, before member 6 enters the slope, by hoist engine 7 to front haulage, after member 6 enters the slope, deadweight by member is glided, and holds member backward by hoist engine 7, makes member slowly descend water until floating fully;
