Description
Technical field
The present invention relates to submerged floating tunnel structure, construction and its control methods in a kind of water over strait, and in particular to a kind of over strait
Submerged floating tunnel structure, construction and its control method in water.
Background technique
The imagination for building the super high-speed rail of vacuum over strait is long-standing.To realize this target, should construct first safe and reliable
Ocean tunnel.
Currently, built ocean tunnel form is seabed tunnel.There are two types of its building methods: one is certain away from seabed
Borehole is built up seabed tunnel (mining method) in the rock stratum of depth or soil layer, and this method construction seabed tunnel is long in time limit, and construction is difficult
Degree is high, and project cost is big, typical such as Great Britain and France's seabed tunnel；Another kind is that the tubular structure of segmentation prefabricating is placed in submarine surface
Or in shallow soil layer, does sealing connection and form seabed tunnel (immersed tunnelling method), this tunnel is because having construction quality guarantee, geology water
The features such as literary condition is adaptable, the construction period is short, project cost is low is gradually used, typical such as port Zhuhai and Macao bridge seabed immersed tube
Tunnel.But immersed tunnelling method seabed tunnel and mining method seabed tunnel also need to depend on submarine soil layer, the depth in tunnel is by seabed
The influence of depth, the seabed tunnel Yue Shen are also deeper.It is limited by the gradient, leading the way for tunnel two sides will lengthen, project cost
Therefore it increases.In addition, immersed tunnelling method tunnel needs to do sealing connection in water, when reaching certain depth, hydraulic pressure is excessively high, antiseep
Technical difficulty increases, or even is limited by diving depth and implement engineering can not.Therefore, from economic benefit and technical difficulty
From the point of view of angle, no matter immersed tunnelling method or mining method, which are not all suitable for deep sea waters, is built tunnel.

Advantage and characteristic: 1, being a kind of environmental-friendly scheme, and the influence to two sides landforms is very small；2, have compared with bridge, tunnel
There is cost advantage, the cost of unit length does not increase with the increase of span；3, it is not limited, can be built in by span and the depth of water
Long span, water level depth, precipitous place.Therefore, submerged floating tunnel in water is studied to be of great significance and the basis of high-speed rail over strait
Engineering.
Submerged floating tunnel is floated in water by means of buoyancy in water, and there are three types of supporting way for it: one, float-type structure works as suspension
When the buoyancy of pipeline is smaller, increase buoyancy using floating drum；Two, riveting is cable-styled, when the buoyancy of pipeline is sufficiently large, is fixed using riveting rope
Pipeline；Three, rigid pile-column, such as water Bridge.
The high-speed rail tunnel (single line) for being about 5.2m for internal diameter, buoyancy are generally greater than its tunnel gravity, therefore, for across
The extra large above-mentioned supporting way one in high-speed rail tunnel there's almost no；And supporting way two, three is fixed on the bottom using riveting rope or pile, this
For deep-sea, such as aforementioned immersed tunnelling method, construct almost infeasible, and there are also the safeties of anchorage style and anchor structure
Vortex-induced vibration (VIV) occurs under flow action for problem -- anchor system, this has fixing intensity of the riveting rope on sea bed very big
It influences.

Stability control is saved, when encountering ocean current disturbance, strong magnetic can be formed in the seawater in drainpipe after being powered to electromagnetic coil
, after electrode plate add voltage, electric current, electric current and magnetic field interaction are generated in drainpipe in seawater and generates Lorentz force,
The power acts on current-carrying seawater and the endwise slip that enables seawater along drainpipe, the reaction of fin-shaped plate and tunnel by seawater
Power, the Electromagnetic Propulsion being horizontally mounted generate horizontal applied force, the Electromagnetic Propulsion vertically installed to drainpipe inland sea water
Vertical active force is generated to drainpipe inland sea water, thus balances ocean current horizontal force and the vertical out-of-balance force in tunnel；
Using the position sensor being arranged on armored concrete fin keel, pass through Beidou or GPS navigation system, Real-time Feedback position letter
Breath changes voltage, electric current in Electromagnetic Control propulsion device, realizes the control of tunnel overall structure, and control precision is Centimeter Level；
Size by adjusting voltage, electric current controls thrust size, by changing the polarity of voltage, i.e. sense of current, control
The direction of thrust, control time are Millisecond.
