Description
Technical field
The utility model is related to a kind of tunnels, belong to tunneling technique control field, escape more particularly, to a kind of double-deck fire-fighting
Raw tunnel.
Background technology
Tunnels and underground engineering is not take up the outstanding advantage of ground land resource with it substantially, is facing " population increasing now
In the big challenge in the 3 of length, shortage of resources, environmental degradation ", increasingly important role is played, therefore, application is more and more wider
It is general, just so-called " having play with entering ".Nearly ten years, tunnels and underground engineering building cause in China's has faster development, not single table
Present tunnel quantity, length of tunnel growth on, and be technically also developed rapidly, in the application side of various engineering methods
Also there is continuous breakthrough in face.Most of China subway tunnel uses shallow burial hidden digging, including part highway, railway tunnel, especially
Shallow embedding mountain tunnel and submerged tunnel.Drill bursting construction dominates Chinese tunnel construction technology for a long time, advances Chinese equipment
Informationization and automated process, for excavating and supporting pipelining, successively independent development hydraulic drill ring, dig dress
A series of equipments such as machine, automation apparatus gunite concrete equipment, arch fitting machine, movable trestle, formwork jumbo, are greatly improved
Working efficiency.Shield, TBM development machines rely on external introduction for a long time, but are equipped for the China of representative with middle iron in recent years
Producer has been achieved with Chinese shield and the autonomous manufacture of TBM, occupies most of China market, extensively should in subway engineering
With, and the carrying that advance geologic prediction is equipped was successfully realized in 2014.In a large amount of engineering practices, single shield of having constantly brought forth new ideas
Shield TBM and open type TBM technologies, solve the problems, such as TBM soft stratum driving get rid of poverty in the settlement Control technology of urban district, shape
It buried into an ultra shallow, big width, small interval rectangular top pipe technology and shield launching, reach zero earthing technology, No. 7 tunnels of wash one's face are drawn in Gansu
It is applied successfully in the engineerings such as No. 6 hole, Chongqing Light Rail lines, creates multinomial world record.In recent years, with complicated geological item
Great burying and long hole line Tunnel Engineering are on the increase under part, engineering investigation fully utilize telemetering remote sensing, multipoint high-frequency physical prospecting,
The technologies such as GIS, GPS, not only increase exploration efficiency, and the grade of control accuracy is also greatly improved.Draw in terms of designing technique
BIM technology is entered, Tunnel Design gradually payes attention to traffic and builds the double effects of art, in terms of tunnel flatness and buried depth
Have compared with quantum jump, emerge a collection of novel tunnel structure type, offspur tunnel etc., and form setting for underground stereo intercommunication
Meter theory, crossings on different level are widely used in highway, railway tunnel and subway, such as Changsha military camp road Xiang River tunnel.It is but existing
Tunnel all directly penetrate through mostly, lack necessary escape route, in this way cave in, fire or tunnel exit are blocked and wait indefinitely
When accident occurs, staff in tunnel cannot escape danger in time, and staff in tunnel can not be realized and be saved oneself, in geologic(al) factor, due to structure
Loosely, it happens occasionally between particle without cementing or cementing difference, cave-in accident.The tunnel cave accident that Geological Hazard is caused
It is very more, and measure of targetedly escaping is not taken in time.Underground water, softening, immersion, erosion, the dissolving for permeating water
The effects that can also aggravate tunnel structure unstability and cave in.Some method for tunnel construction selects improper or inter process away from arranging not
Rationally, each process spacing is too long for gap, and stratum exposure duration too long, causes wall rock loosening, weathering, leads to the generation caved in.
