Description
Technical field
The present invention relates to immersed tube tunnel technical field, more particularly to a kind of large-scale component sliding lubricating oil and concocting method,
Deployment device.
Background technology
Port Zhuhai and Macao bridge island tunnel engineering seabed immersed tube tunnel total length is 5664m, is made up of 33 tube couplings, single standard pipe
Long 180m is saved, about 7.2 ten thousand tons of weight, each tube coupling is made up of 8 long 22.5m section, and the weight of each section also reaches several
Kiloton, tube coupling use the piping lane section form of holes one, wide 37.95m, high 11.4m.
Tube coupling is prefabricated to use segment matches prefabrication：1# segmental constructions are completed pouring pedestal, treat that 1# sections concrete reaches
After moving intensity to pushing tow, by tube coupling, pushing tow moves 22.5m forward（I.e. single segmental length）, match and pour 2# sections；2# is saved
After section reaches pushing tow movement intensity, together with 1# sections, pushing tow moves 22.5m further along, and matching pours 3# sections；It is complete by that analogy
Into pouring for 8# sections, and most pushing tow moves about 130m to shallow dockland to the tube coupling of 8 section compositions forward at last.
The movement of tube coupling using bottom multi-point support successively incremeantal launching method technique：In tube coupling bottom, 4 thrusting slip beams are set
Track, the thrusting slip beam orbit are arranged in below two side walls and two middle walls, arrange multi-point support on track, and use
Pushing tow jack provides the jacking force of tube coupling.Multiple support jacks are arranged on thrusting slip track, are pacified in support jack
Before putting, the base of each support jack needs to install polylith PTFE slide plates, and during pushing tow, jack passes through slide plate and track
Contact slide.
Tube coupling is moved based on selection pushing tow mode, when using pushing tow system pushing tow tube coupling, due to the distance of passage,
Pushing tow weight is big, it is necessary to the coefficient of friction resistance of control jack and interorbital strictly be controlled, if the coefficient of friction resistance is too high, it will cause
Pushing tow is difficult so that and the maximum static friction force overcome needed for pushing tow system is excessive, and this will cause pushing tow system pump group faults frequent,
And PTFE slide plates are caused to be more easy to abrasion deformation, reduction of service life.Therefore, how to control reduces jack and interorbital phase
The emphasis of whole pushing process is turned into the coefficient of friction resistance of motion.
Signified large-scale component refers to that the physical dimension of component is more than 30m × 10m in the present invention.
The content of the invention
It is an object of the invention to：For large-scale component in the prior art in slipping, due to its coefficient of friction resistance mistake
Greatly, cause easily to send out failure for providing the power-equipment of power resources, easily abrasion deformation occurs for slip basic face the problem of,
There is provided a kind of large-scale component sliding lubricating oil and its concocting method, deployment device, the lubricating oil of the invention can effectively reduce large-scale
The coefficient of friction resistance of the component in sliding, large-scale component is set to avoid power-equipment that power failure occurs when sliding, meanwhile, effectively
Two rubbing surfaces of two pairs of slips of protection, reduce the abrasion deformation between rubbing surface.
In order to realize foregoing invention purpose, the invention provides following technical scheme：
A kind of large-scale component slides lubricating oil, including following components in percentage by weight：Machine oil 70~77%, molybdenum sulfide 23~
30%。
Because large-scale component has, volume is big, the big characteristic of weight, is fitted using molybdenum sulfide as component therein, molybdenum sulfide
For under hyperbaric environment, molybdenum disulfide be by natural molybdenum concntrate powder change molecular structure after chemical purification and made of solid powder
Agent, it is added in machine oil, inadherent alternating state can be formed, substantially increases the lubricity of machine oil, and formed
Protection to slide plate, extend the service life of slide plate.
After molybdenum sulfide is process by supersonic jet mill, its granularity can reach 325-2500 mesh, its microparticle hardness
1-1.5, coefficient of friction 0.05-0.1, use it for being added to enabling in machine oil and play preferable antifriction function.
Using machine oil and molybdenum sulfide, all there is more preferable friction reducing effect than other lubricants, while take above-mentioned cooperation
Than reaching preferable effect, the coefficient of friction resistance can be greatly lowered, meet the coefficient of friction resistance of design requirement, avoiding as large-scale component
Slide and the power-equipments of power resources is provided taken place frequently failure, meanwhile, it is effectively protected the cunning for supporting large-scale component to slide
Plate, avoid it that abrasion deformation occurs, add the life-span of slide plate.
Preferably, the percentage by weight of component contained by lubricating oil is：Machine oil 73~76%, molybdenum sulfide 24~27%.
Large-scale component is in slipping, it is necessary to the strict controller coefficient of friction resistance is controlled, when coefficient of friction resistance control is designing
In the range of when, whole slipping is safe, including power-equipment, abrasion deformation and service life etc..Take above-mentioned percentage
The component of ratio, the coefficient of friction resistance of up to ten thousand tons of large-scale component can be made to control within 6%, large-scale component is smoothly realized transfer, should
