In the current society that this runs at high speed, there are countless people and thing daily in each intercity quick flowing
, and everybody can with selection mode be also diversified, steamer, aircraft, car and railway etc. are all relatively common
The vehicles.And develop with the continuous creation of rail industry, increasing people more likes selecting rail service.
The construction of Chinese high ferro originates in " 11 " five planning period.To year ends 2015, China Express Railway revenue kilometres
Will be up to 1.8 ten thousand kilometers, using high-speed railway as skeleton, including the structure such as area border speed rail, inter-city passenger rail and Line of Existing Railway circuit
Into speed rail net build up substantially, total scale is up to more than 40,000 kilometers, 500,000 population above cities of basic covering.Chinese high ferro
Leap development so that the high railway network becomes to extend in all direction, and the people in each place can enjoy the high ferro service of high quality,
Allow people trip condition can become it is incomparable smoothly with easily.High ferro is risen in each province and city, or even counties and districts, cities and towns, is not only changed
Become the economic development in area, also change the trip life of people, it has also become the epoch artery between contemporary cities.
Although present high ferro has substantially reduced people's trip time on the way, people are to speed and efficiency
Pursuit never stops.Under unlimited atmospheric condition, the principal element of restriction high ferro highest economic pace is dense air：It is empty
Square into approximate proportional relation of atmidometer and train running speed, speed improves 2 times, and air drag will increase to 4 times.Work as train
When traveling with 200 kilometers per hour, air drag accounts for 70% of drag overall or so；Harmony CRH380A is run in Beijing-Shanghai express railway
When going out 486.1 kilometers of speed per hour, aerodynamic drag has exceeded the 92% of drag overall；If going to more than 500 kilometers, in drag overall, 95%
All it is aerodynamic drag above.Bullet train speed per hour is more than 400 kilometers, energy consumption and noise severe overweight, nothing in dense atmosphere
Method puts into commercial operation.If enclosed tunnel can be built, low vacuum is pumped into by being evacuated station, the superelevation of bullet train is can be achieved with
Speed operation, i.e., " vacuum tunnel superexpress train ".
China is vast in territory, and seashore line length, river, river, lake and island are numerous.High ferro is also required to pass through above-mentioned water outward
Domain.It is in recent years to use the submerged tunnel mode small to environment, landscape impact more.Working as in the future needs extra long distance ultrahigh speed water-borne transport
When, it is then preferable selection using " vacuum tunnel superexpress train " under water.For vacuum submerged tunnel joint waterproofing and airtight
Property is one of key factor of whole engineering success or failure.It is how quick, convenient, vacuum tunnel is economically built in water, and ensure
The sealing and air-tightness of its joint will be one of technical problems that following submersible vacuum tunnel faces.

Put on joist, joist is arranged in pile foundation；Lead under the prefabricated vacuum water of the adjacent segmented of each two between tunnel box-beam structure
The bolt hole that drawing bolt is crossed with drawing pedestal is fixedly connected, and is provided with rubber fastening band and buffering between two drawing pedestals
Bed course.
Preferably, tunnel box-beam structure and drawing pedestal are integral type structure under the prefabricated vacuum water of described segmented.
Preferably, the length of tunnel box-beam structure is not less than 120m under the prefabricated vacuum water of described segmented.
Preferably, described rubber fastening band is arranged on the inner side of the bolt hole of drawing pedestal.
When the utility model is operated, tunnel line plane, vertical line type are fitted according to underwater topography and line requirements；
According to circuit is flat, vertical line type, tunnel box beam is divided into some sections；Under the prefabricated vacuum water of segmented between tunnel box-beam structure
Pile foundation and joist are set near jointing, and joist top surface absolute altitude is identical with tunnel structure floor level；Applied in pile foundation and joist
While work, tunnel box-beam structure under the prefabricated prefabricated vacuum water of segmented；By tunnel under drawing pedestal and the prefabricated vacuum water of segmented
Road box-beam structure is simultaneously prefabricated, forms overall；Waterstop is arranged on the outside of drawing pedestal；Box beam is lifted on underwater pile
Afterwards, tunnel box-beam structure drawing under the prefabricated vacuum water of segmented is connected to form tunnel by drawing bolt；By air in tunnel
Discharge forms vacuum submerged tunnel.
After said structure, what the utility model was produced has the beneficial effect that：Tunnel under vacuum water described in the utility model
A kind of joint connection manner in road, tunnel joint is connected with the drawing of drawing bolt, and manufacture difficulty is small, difficulty of construction is small, installation side
