Description
Technical field
The present invention relates to a kind of from cable-free type seabed deformation long-term observation device is bored, belong to ocean observation technology field.
Background technology
In coastal region, silt transports rapid subsidence and piles up by the remote of river, in ocean hydrodynamic force (ripple
Wave, ocean current, tide etc.), the soil body deadweight and bioturbation under there is a series of dynamic changing process, including sediment consolidation pressure
Close process, liquefaction Rheologic, erosion settling flux migration process, along with the composition of deposit, structure, thing during these
Reason mechanical property and the change of engineering geological property occurrence dynamics, and then trigger littoral zone erosion, harbor siltation, submarine landslide, turbid
The marine geologic disasters such as stream, so as to cause considerable damage to the ocean engineering facility such as offshore platform, submerged pipeline, submarine cable.
In above-mentioned marine geologic disasters, submarine landslide monitoring difficulty is larger and endangers surprising.However, not monitoring hand preferably at present
Section obtains the generation evolution process of submarine landslide, seriously constrains research of the scholar to its disaster mechanism.
Submarine landslide is the horizontal sliding deformation between a kind of Different Strata, by laying vertical deformation measurement pipe/cable/bar
It is the most direct, accurate observation procedure.At present, this kind equipment can be divided mainly into 3-axis acceleration sensor measurement and optical fiber
Measure two classes.Wherein, the former Typical Representative is SAA array displacement meters, is serial with a series of 3-axis acceleration sensors
Connection, obtains the displacement process of each point, and then obtains whole transversely deforming observation process.Optical fiber measurement can be divided into continuous point
Cloth optical fiber measurement and FBG quasi-distributed optical fibers are measured, and its function is essentially identical with SAA with external structure.
However, industry does not have preferable arranging device or method at present, the seabed original position cloth of this kind equipment can be completed
Put.Observation device original position in deposit lays, and conventional method includes gravity injection, piling injection, drilling injection and quiet
Power injection.
Gravity injection is the lowering velocity by controlling hawser, or accurate calculation injected body form, buoyant weight, center of gravity position
Put, by the method similar to freely falling body, the method that control injected body enters deposit.Its device fabrication is simple, but is subject to
Machining accuracy, calculation error, the influence of site environment, will as expected realize the injection operating process of designated depth, attitude, difficulty
Greatly.
Piling injection is often injected body is initially entered into the soil body first with gravity injection method, then by built-in or outer
The pile driving equipment for connecing, by way of driving piles repeatedly, makes injected body reach designated depth；Seabed static sounding is used for reference in static(al) injection
Technology, using bottom-sitting type injection platform, is driven by motor or hydraulic press etc., during injected body delivered into deposit using manipulator
Specified location.But, piling injection is directed to rigid submarine observation feeler lever with static(al) injection method, it is difficult to flexibility
Deformation measurement cable is operated effectively.
Conventional boring method is used for reference in drilling injection, after hole is drilled by injected body by drilling pipe along entering to sea-bottom deposit
In thing, then by backfill, " injection " process is completed.The method is reliable and stable, but high cost, time are long, and injected body with it is heavy
The fitness of product thing is excessively poor.For the 5m depth that deformation measurement cable is typically used lays, traditional boat-carrying rig punching
Lay that mode process is complicated, hole utilization rate is extremely low, and then cause to lay cost and be difficult to bear.
At present, the deformation measurement cable of flexibility is directed to, lacks effective original position arranging device and method and technology.Serious restriction
Research of the scholar for the Serious geological disasters process mechanism such as submarine landslide, also to the ocean engineering of early warning and monitoring cannot be realized
The processes such as construction, offshore production constitute serious potential hazard.

Further, observation device each several part of the present invention need to meet relationship below：
The observation device of the present invention that machines of order, quality is m in recoverer its air based on main control cabin1, body
Product is V1；Quality is m in overall its air in bit part, deformation measurement cable and indwelling portion2, volume is V2.According to document analysis and
Marine observation experience, observation device lays process preferable decrease speed υ in the seawaterdIt is 1~3m/s, is can use in specific works
Uniform descent speed υ under stable stated=1.5m/s (whole parameters are set to scalar in the present invention).
During observation device lays, suffered external force includes gravity (G), buoyancy (FIt is floating) and seawater resistance (FResistance).Wherein,
Gravity is downward, buoyancy is upward, seawater resistance is opposite with the direction of motion.According to Bernoulli equation, seawater resistance and decrease speed, dress
The stress cross-sectional area S (vertical projected area) for putting is relevant.Enter the primary stage of water in observation device, decrease speed is 0,
Now seawater resistance is smaller.Constantly increase with decrease speed, seawater resistance also increases therewith, and acceleration constantly reduces.Work as acceleration
Degree is reduced to 0, reaches stable state.Make the resistance coefficient of seawater for C, now have

Fs>1.2k×(L0- Lz) (formula 7)
Can be according to above formula, in k, L of known spring0, and FsUnder conditions of, determine spring under compression initial
Length Lz。
When acoustic releaser starts, snak link drawstring comes off, and spring discharges from squeezed state.Recovery based on main control cabin
Portion starts to float so that underwater electrical connector two-end-point distance is from LbTo La.Now, under spring force effect, underwater electrical connector two
The stretching that oversteps the extreme limit is held, and then is separated.I.e.
k×(La- Lb)>Fa(formula 8)
For the sake of assurance, required in real work
k×(La- Lb)>1.2Fa(formula 9)
Can be tested by destroying for times, determine Fa.According to snak link correlation computations, L is determined0And Lz, as LaWith Lb's
Restrictive condition.Then according to above formula, under the conditions of the k of known spring, L can be determined according to the model of underwater electrical connectoraWith LbTake
Value.
