Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of method utilizing small lifting equipment to install super-heavy component under water,
Use small lifting equipment, component to be installed and the floating drum that is fixed together with this component are hoisted to below the water surface；After floating drum is progressively immersed in the water, due to the buoyancy of floating drum, the lifting capacity that small lifting equipment undertakes gradually decreases, and small lifting equipment incrementally increases work range, until it reaches installation position；After component is in place, to floating drum water-filling, floating drum separates with component, and floating drum hangs out the water surface, starts the next one and installs circulation.
The present invention utilizes floating drum 1 to coordinate small lifting equipment 6 to complete the installation of superduty component lifting under water.Component and floating drum 1 are hoisted to together nearest to meet the position that the depth of water requires and be advisable by small lifting equipment 6 to meet.Floating drum 1 is generally made into cube shaped, and the weight of the buoyancy of floating drum 1 and component 2 to be installed deducts the buoyancy of component 2 itself and matches.Floating drum 1 shell is typically made by the steel plate of thick 4 ~ 6MM, and inner skeleton is lightweight steel construction.
Floating drum 1 is provided with reserved cavity 9, and the making of reserved cavity 9 requires: after floating drum 1 fills water, the gravity of the floatage energy of this reserved cavity 9 just balanced floating cylinder 1.This reserved cavity 9 totally 4, is symmetrically arranged in four corners on floating drum 9 top.Reserved cavity 9 arranges relieving device 17 at lowest part, when this relieving device 17 runs, seals with lid, twists the lid off during maintenance, and emptying may penetrate into the infiltration in cavity 9 in running.
Breather 4 ensures when to floating drum 1 water filling, discharges the air in floating drum 1, it is ensured that water filling smoothly completes, and the general plastic flexible pipe using φ 10 ~ 15MM, the joint on floating drum 1 is combined fastening, it is ensured that airtight.This breather 4 end picks out the place to the outer safety of the water surface 18.
Water injection hole valve 15 is contact valve, sets rubber water-proof sheet with floating drum 1 contact position.Rubber water-proof sheet one end hinged on floating drum 1, the other end takes and is held on floating drum 1.
Valve opening device 14 is crank structure, and middle part is hinged on floating drum 1, and valve opening device 14 one end connects at the switch of water injection hole valve 15, and valve opening device 14 other end connects with the control line 10 of water injection hole valve 15.When needing, gently draw control line 10, open water injection hole valve 15.
Hanging on the suspension hook 3 of small lifting equipment 6 by one end of floating drum 1 by the first suspension ring 12, the other end is connected with component 2 to be installed by the second suspension ring 16.
Floating drum 1 is run through by the steel pipe 10 of φ 80MM, and control line 10 is through steel pipe 10, and control line 10 one end is connected to diving boat or on the bank；Control line 10 other end connects water injection hole valve 15.It is easy to manually hold control line 10 from the water surface and opens the water injection hole valve 15 bottom floating drum.
Concrete enforcement step is as follows:
①: small lifting equipment 6 be installed to rockfill dike 7 in place → 2.: floating drum 1 is hung on the suspension hook 3 of small lifting equipment 6, and the floating drum 1 sling → 3.: hang component to be installed 2 → 4. for 1 time at floating drum: floating drum 1 and component 2 one to be installed are lifted to the water surface nearest from rockfill dike 7 bank → 5.: when being progressively immersed in the water until floating drum 1, small lifting equipment 6 progressively luffing, until meeting the amplitude of installation requirement → 6.: component 2 to be installed install put in place → 7.: pull the control line 10 of water injection hole valve 15, water → 8. is filled: component 2 to be installed breaks off relations → 9. in floating drum 1: floating drum 1 emerges → 10.: close water injection hole valve 15, start the next one and re-mount circulation.
