Specific implementation method
For technological means, creation characteristic that the present invention is realized, achieve the goal and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
A kind of steel float tank deposition plan position control method, a plurality of spacing piers at first are set in the steel float deposing position, the layout of position limiting pile as shown in Figure 1, spacing pier is four, spacing pier I is arranged on steel buoyancy tank width one side in the pump house, spacing pier II is arranged on steel buoyancy tank length one side in the lock chamber, it is outer and parallel with spacing pier II that spacing pier III is arranged on lock chamber, spacing pier IV is arranged in the hoist house and is relative with spacing pier I, it is 15cm that steel buoyancy tank design sideline is left in spacing pier II and spacing pier III sideline, and it is 50cm that spacing pier I leaves in the sideline steel buoyancy tank.
Referring to Fig. 2, each spacing pier is divided into the steel pipe pile 3 of 4 Φ 800mm * δ 14mm, the long 35m of stake, and pier is of a size of 4.6 * 4.6 * 1.5m, and structural elevation is+3～+ 4.5m; Wherein the spacing pier in west side utilizes the hoist house basis, and pile foundation is 5 Φ 800 * δ 14mm steel pipe piles 3, and key dimension is 10 * 13 * 2m, and structural elevation is+4.3～+ 6.3m.
Spacing pier also has protection pump house pile foundation safety effect concurrently except that using for steel buoyancy tank location.The stake of spacing pier and the stake of pump house and hoist house construction simultaneously, the structure construction of spacing pier is interspersed in bedding construction period, structure C 30 concrete are by base agitator supply, and the olive car is transported on the embankment of works area, reuse suspension bucket and are transported to construction location and build for small-sized waterborne.Spacing pier adopts one-time-concreting to the top, than the needs of garage basis according to structure, divides secondary to build and can finish.Spacing pier pier shaft end face is embedded with set bolt (not signal), is used for fixing facilities such as hoist engine and mooring dolphin.
Referring to Fig. 3, the steel buoyancy tank can be divided into a plurality of identical or different separations according to different needs, and what adopt in the present embodiment is different separations, is not limitation of the present invention.The height of steel buoyancy tank from base plate to designing requirement, Cast-in-place concrete comprises gate floor 6750m
3With a spot of lock wall pier concrete 945m
3, steel work deadweight 3200t, thus whole steel buoyancy tank gross weight at 19465t, force-bearing situation such as following table before the base plate counterweigh.
Stressed dress condition before the steel buoyancy tank counterweight
| Separation | A | B | C | D | E | Add up to |
| Separation length (m) | 16.5 | 40 | 21 | 21 | 18 | 116.5 |

Referring to Fig. 4, under the traction of tugboat, enter construction area after the leveling of steel buoyancy tank, divide fix the steel buoyancy tank at 4 by mooring dolphin on the spacing pier and hoist engine, tugboat 1 leaves then; Start hoist engine, slow carry under the escorting of tugboat 2.During near the position, spacing pier II and spacing pier III close on steel buoyancy tank side wide 12cm locating part are installed at the steel buoyancy tank, and beam limit and steel buoyancy tank limit are reserved with the surplus of 30mm; Face steel buoyancy tank side at spacing pier I spacing crossbeam is installed, the wide 47cm of crossbeam, cross beam edges and buoyancy tank limit are reserved with the surplus of 20mm.
At steel buoyancy tank outer wall, 14 inlet valves are set, valve is opened and closed by manually-operated, and each valve flow of inlet water is controlled at 500m
3About/h.After the steel buoyancy tank carry, after required precision is satisfied in check, the sinking of can pouring water.Manually start water intaking valve by the predetermined speed of pouring water, the steel buoyancy tank is steadily sunk down on the bedding.At last, closed shutter makes to keep in the steel buoyancy tank water level to+3.0m, in case steel buoyancy tank come-up.
Referring to Fig. 5, steel float deposing is chosen in the flood slack period, and beginning carry time is preceding 2 hours of flood slack, rule of thumb, in 2 hours the steel buoyancy tank accurately carry between spacing pier, utilize the sinking that begins to pour water of slack tide position then, these can guarantee steel buoyancy tank installation accuracy.
Referring to Fig. 6, after the steel buoyancy tank sinks,, need the packed sand of symmetrical backfill around the steel buoyancy tank for preventing the displacement of steel buoyancy tank.Make an appointment with extremely-the 8.8m absolute altitude in the first backfill steel buoyancy tank of the needs outside during backfill, is bank side and upstream and downstream then, and the backfill absolute altitude is-7.3m.
After backfill put in place around the steel buoyancy tank, promptly dismountable spacing pier I, spacing pier II and spacing pier III by small-sized crane ship waterborne, were equipped with special facility and remove spacing pier, were equipped with electrically operated hammer by crane ship then and extracted spacing pier steel pipe pile 3 recovery.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present invention; under the prerequisite that does not break away from the principle of the invention and scope; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
