Description
Technical field
The present invention relates to underwater project construction field, especially a kind of continuous leveling ship of floating underwater rubble bedding.
Background technique
Immersed tunnelling method is a kind of construction method in water-bed building tunnel.Immersed tube tunnel exactly floats several precast sections respectively
Sea (river surface) scene is transported to, and sinking is mounted in the foundation trench dredged one by one, the water built in this approach
Lower tunnel.To avoid basic local high spot, immersed tube bottom slab stress is uniform, the rubble pad of design high-precision leveling between bottom plate and ground
Layer is used as bedding, need to flatten highly accurate dedicated blotter laying ship and construct.
Representative ship is the straight tubular type stone dumper of dynamic positioning under DEME consortium
" FLINTSTONE ", it is maximum stone dumper in the world.The ship uses DP/DT dynamic positioning, is not required to towboat assistance, can be in neighbour
It is operated within the scope of nearly 500 meters of platform structure, operating water depth is up to 2000m.Its jackstone guard system has active lifting compensation ROV's
Measuring system, including multi-beam, echo depth sounder and on-line processing system, it is considered to be most advanced in the industry.But floating dynamic
The positioning accuracy of stone dumper is difficult to reach cm grades, and the transverse shifting of ship direction of travel and jackstone pipe is difficult to precisely form such as Z-type
Bed course.Jackstone protection of the protection of oil platform, Large marine wind power foundation and submarine cable etc. is usually only applicable to surface layer
The not high project of required precision is not suitable for the laying of immersed tube bedding.
More advanced support platform formula jackstone leveling ship " KUS- is used in South Korea's Busan-Geoje constructing tunnel
[leveling ship is integrated with rubble and casts, flattens and detection function ISLAND ", substantially merges support platform structure and with compensation
The jackstone guard system of device, and mating exploitation construction management system, platform-type laying ship is since platform lifts away from the water surface, ship when operation
Body is not influenced substantially by wave, wave, stream；It can also be flattened when sea conditions are good with floating state, it is strong to adapt to operating environment ability.It throws
Madreporic canal management system can accurately detect and control elevation and the position of cloth tube discharge port, and leveling precision is high."KUS-ISLAND"
It is surveyed in Pusan tunnel and is laid with synthesis precision, add up elevation and flatness, reaches ± 40mm.The disadvantages of the method are as follows cost is extremely
Valuableness, and spud leg needs to be inserted within the scope of tunnel bedding groove, there is certain destruction to ground.
Chinese patent literature CN107489154A describes a kind of deep-sea base bed flattening construction method, passes through the movement of hull
Realize jackstone, the problem is that, hull is influenced in moving process by wave, and construction precision is not high.Chinese patent text
It offers 208328938 U of CN and describes a kind of rubble leveling device, the X of jackstone pipe, Y-direction are realized by the frame-type platform of setting
Walking, is implemented as the jackstone of " Z " font.But need to move integrally hull after completing a construction area using the program,
It repositions, during repositioning, needs to rely on the positioning accuracy of GPS, it is slow that there are locating speeds, and positioning accuracy difference is asked
Topic.Further, the scheme of stroke adjustment is carried out wherein also describing and stretching repeatedly by hydraulic cylinder control balance pipe, but by
It is influenced in by water flow and stormy waves, the holding of jackstone pipe is difficult vertically, although describing inclinometer in the description, simultaneously
The flatness for how ensuring bedding according to the inclined degree of inclined degree amendment jackstone pipe is not recorded.Further, due to liquid
Cylinder pressure is located under water, and each hydraulic cylinder has oil inlet and oil return pipe, and it is extremely difficult for carrying out accurate control to multiple hydraulic cylinders
, more hydraulic oil pipe keeps the elevating control of jackstone pipe very troublesome.Further, above-mentioned file, which also describes, utilizes leveling
Head goes to strike off bedding, but as the length of jackstone pipe increases, the bending deformation of jackstone pipe increases, and the leveling precision of the program is difficult
With control.
