In many tunnel incident, because the accident that preliminary bracing unstability leads to the tunnel door closing is comparatively common, it can lead to construction worker stranded even buried in the tunnel, and is very big to operation personnel's life safety threat nature. In view of the above situation, the most commonly adopted countermeasure at present is to arrange an escape pipeline in the tunnel along the longitudinal direction, so that construction workers can evacuate from the vicinity of the tunnel face to the vicinity of the secondary lining structure of the tunnel through the escape pipeline under the condition of being trapped, thereby ensuring the life safety of the construction workers. At present, the conventional escape pipeline is formed by longitudinally connecting a plurality of steel or other high polymer circular pipe joints, the connection strength of the pipeline joints is relatively weak, and the pipeline has the problems of lateral deviation, impact or extrusion deformation, pipe joint dislocation and the like under the impact action of earth and stones. Meanwhile, due to the limitation of tunnel construction, the escape pipelines which are longitudinally arranged are in a suspended state in an inverted arch construction section, the existing escape pipelines are too weak in protective performance, and if the existing escape pipelines are hit by collapsed soil and stones or supporting structures, the risk of breakage is very high.

the above process is repeated until the tunnel is through.
Wherein, when the tunnel country rock condition changes, can be according to actual conditions, the automatic couple of formula is jensed to the accessible, adds or reduces portable pipe car 9 and flatbed trailer 11's quantity.
The brief introduction of the specific escape process is as follows:
when a tunnel accident causes construction workers to be trapped, the conditions in the tunnel are known firstly, and then a proper rescue method and a rescue position are selected according to specific conditions:
(1) because the whole stress state of the primary support of the poured inverted arch section is better, the poured inverted arch position can not collapse under most conditions and is in a relatively safe state, so when the collapse occurs at the front end of the poured inverted arch, and the poured inverted arch position for parking the cantilever type escape and rescue vehicle is in a relatively safe state, the following rescue actions are adopted:
the waterproof plate trolley or the secondary lining trolley in the hole is moved to the poured inverted arch section in front of the hole so as to ensure the safety of the section in the rescue period, and other reinforcement measures can be taken to further reinforce the primary support of the section if necessary;
after the reinforcing measures are finished, the rescue personnel take rescue actions in place at the position of the rescue bin 201 of the cantilever type escape and rescue vehicle;
trapped people enter the third high-strength escape pipe section 15 through the traction vehicle head 6 with openings on two side edges, move into the first high-strength escape pipe section 8 at the front end of the truss type trestle 202 through crawling, and evacuate into the rescue cabin 201 through the conveyor belt 1301 arranged in the first high-strength escape pipe section 8. The rescuers waiting here will carry the trapped person onto the stretcher and immediately send to the hospital for the relevant rescue. When the trapped people are injured and inconvenient to climb, the rescue hauling rope 17 can be bound on the body, and the rescue workers can help the trapped people to evacuate in a pulling mode;
meanwhile, the rescue personnel can start the rescue material pipeline system 14 according to the condition of the trapped personnel in the tunnel, and ventilate, supply water, supply nutrient solution or other necessary food to the trapped personnel in the tunnel through the pipeline supply connecting port 1402 and the rescue material conveying pipeline 1401 so as to ensure the life safety of the trapped personnel.
(2) When the collapse scale is large, the primary support of the poured inverted arch section for parking the cantilever type escape and rescue vehicle collapses, and the waterproof plate trolley or the secondary lining trolley cannot move forward to the position, the following rescue actions are taken:
the rescue personnel are in position at the tail end of the pipeline trailer to carry out rescue operation;
trapped people enter the third high-strength escape pipe section 15 through the traction vehicle head 6 with openings on two side edges, move into the first high-strength escape pipe section 8 at the front end of the truss type trestle 202 through crawling, and then enter the rescue bin 201 through the conveyor belt 1301 arranged in the first high-strength escape pipe section 8; then enters the sliding ladder type high-strength escape pipe section 10 on the sliding ladder type trailer 4 through the pipeline connecting port at the rear side of the rescue bin 201, climbs through the second high-strength escape pipe section 12 on the flat trailer 11, reaches a safe position near the secondary lining of the tunnel, and then the rescuers in position send the trapped people to the hospital for related rescue.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiment according to the technical spirit of the present invention without departing from the technical spirit of the present invention are within the scope of the present invention.
