Therefore, conventional long-range road tunnel tunnel escape speed and evacuation capacity have following deficiency:
1. for three tunnels, hole, track, side has an accident in hole, and escape personnel enters piping lane hole through fire resistant doorsets, and the 50～150m that need to walk gets to the emergency exits in hole, other side track, and escape speed is slow.
2. for three tunnels, hole, if escape personnel selects to escape in piping lane, need to going to tunnel portal, Travel distance is bigger, and effect is worse.
If 3. track, side evacuated pore is faced in escape personnel's entrance, cause and face track, side hole personnel accumulation.In wagon flow artificial abortion's situation, cause hidden peril of accident.
4. escape personnel constantly enter face hole, track, side escape not substantive out of danger, evacuation time is long brings escape personnel's fear to strengthen, and should cause secondary disaster.
5., for holes tunnel, if hole, two tracks has an accident simultaneously, escape and evacuation difficulty strengthens.
Summary of the invention
Because the drawbacks described above of prior art, the present invention provide a kind of can the cut and cover method tunnel structure of fast-escape, it is characterized in that, comprising: tunnel structure main body includes at least two Tunnel-holes (being both formed in below ground), mid-board between described two Tunnel-holes is provided with some fire resistant doorsets, each described fire resistant doorsets place is correspondingly provided with a cat ladder, on the top board at the top of each described cat ladder of correspondence of tunnel agent structure, offering for the escape hole towards ground greening belt, the aperture in each described escape hole is provided with by the outside unidirectional trapdoor opened in tunnel.
Preferably, the trapdoor of the present invention is automatically controlled hydraulic door or mechanical type enabling gate.
In certain embodiments, described cut and cover method tunnel structure is three hole tunnel structures, and in centrally located piping lane Tunnel-hole, (during three tunnels, hole, escape personnel then may select in the passway for escaping in piping lane and moulds cat ladder escape by steel passway for escaping；For three tunnels, hole, escape personnel moulds cat ladder either directly through steel and escapes to ground after being entered piping lane storehouse by fire resistant doorsets by hole, track, side).
In certain embodiments, described cut and cover method tunnel structure is holes tunnel structure (now, when the described Tunnel-hole accident early period of origination of side, the Tunnel-hole of opposite side is likely to also in running status).
In certain embodiments, described cat ladder is that cat ladder moulded by steel.Described steel moulds cat ladder for commercially product.
Meeting on the basis of this area general knowledge, above-mentioned each optimum condition, can combination in any, obtain each preferred embodiment of the present invention.
Beneficial effects of the present invention: cut and cover method tunnel structure of the present invention, it is possible to evacuate on escape system basis in tradition, reduce evacuation time, improve the evacuation capacity in tunnel.When fire occurs, the tunnel structure of this fast-escape, it is possible to personnel are routed to ground face by the very first time, maximum possible ensures the personal safety of escape personnel.
Below with reference to accompanying drawing, the technique effect of the design of the present invention, concrete structure and generation is described further, to be fully understood from the purpose of the present invention, feature and effect.

Detailed description of the invention
Name a preferred embodiment, and become apparent from intactly illustrating the present invention in conjunction with accompanying drawing.
Embodiment
It is an object of the invention to be achieved through the following technical solutions: as shown in Fig. 1～Fig. 2, the present embodiment provides a kind of cut and cover method tunnel structure, and this tunnel agent structure includes two Tunnel-holes or three Tunnel-holes that are formed at ground less than 1；For isolating the mid-board 7 between first Tunnel-hole 2 and second Tunnel-hole 2, being provided with a number of fire resistant doorsets 5, each fire resistant doorsets 5 are all correspondingly arranged on the top board of the tunnel agent structure on corresponding each cat ladder 4 top of cat ladder 4 (such as: cat ladder moulded by steel) and all offer an escape hole leading to ground greening belt.
Escape hole adopts trapdoor 6 to close at ordinary times.Trapdoor 6 adopts the hydraulic door or mechanical type enabling gate that electronic system controls, and trapdoor 6 only can be outwardly opened by tunnel, and under even in everyday situations, layman does not open in the external world.
During tunnel structure uses, when side Tunnel-hole accident early period of origination, opposite side Tunnel-hole can also in running status.Therefore, for three tunnels, hole, escape personnel moulds cat ladder either directly through steel and escapes to ground after being entered piping lane storehouse by fire resistant doorsets by hole, track, side.
And for holes tunnel, escape personnel can run away to ground greening belt either directly through cat ladder.Assigning two Tunnel-holes when administrative center and stop transport after order, escape personnel may select and takes breakdown lorry escape in hole, track, side facing, it is possible to select to mould cat ladder escape by steel.
It addition, as it is shown in figure 1, for three hole tunnel structures, if the Tunnel-hole of both sides 2 all has an accident, escape personnel then may select and moulds cat ladder escape at the steel from the centrally located passway for escaping hole 3 being located in piping lane；If holes tunnel, then escape personnel either directly through this side or faces the steel that side arranges and moulds cat ladder and run away to ground.
