Description
Technical field
The utility model relates to tunnel, in particular to a kind of High aititude railway tunnel auxiliary for taking into account construction, ventilation of taking precautions against natural calamities
Tunnel liner structure.
Background technique
With China express railway road network fast development with it is perfect, High aititude railway engineering is also more and more, due to work
The increase of journey elevational position causes engineering construction surrounding air gradually thin, and air pressure reduces, and air oxygen content also accordingly reduces,
And then there is the construction in many High aititude tunnels and ventilating problem of taking precautions against natural calamities.
It is mainly solved the above problems by the way of tunnel ventilation at present, common Tunnel Construction Ventilation Types mainly have certainly
Right ventilation, forced, pull-out type, hybrid, laneway type and wind canal formula.Wherein, wind canal formula draft type passes through plenum partitions
Service gallery is divided into two parts up and down, ventilation by ducts is formed in same service gallery, plays and High aititude tunnel is applied
Save the cost is played the role of in work ventilation and ventilation of taking precautions against natural calamities, and improves only head ventilation length and ventilation effect.But wind canal is used at present
The tunnel example of formula ventilation is less, however it remains following point:
One, current wind canal formula plenum partitions use the materials such as color steel tile, color steel plate substantially, and ventilating duct overall tightness is not
Strong and operation difficulty is larger, therefore air duct air leak rate of air curtain is easy to be affected and then reduces ventilation effect；
Two, that commonly uses wind canal formula plenum partitions applies that quality requirement is more stringent, will affect the integral construction progress in tunnel；
Three, service gallery plenum partitions are removed after construction is completed, and service efficiency is low, also results in material
Waste is unfavorable for reducing project cost.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of High aititude railway tunnels for taking into account construction, ventilation of taking precautions against natural calamities
Road service gallery liner structure improves only head ventilation length in service gallery construction period to make full use of plenum partitions structure
And ventilation effect, service gallery and Emergency Assistance station are integrated during tunnel operation, to advantageously reduce tunnel
Construction cost.
The High aititude railway tunnel service gallery liner structure for taking into account construction, ventilation of taking precautions against natural calamities of the utility model, including tunnel
Road structure and coupled logical service gallery structure, it is characterized in that: fixed setting mould builds coagulation in the service gallery structure
Native partition, transverse ends and the service gallery structure of form concrete partition are connected as one, and service gallery structure is separated
Upper channel and lower passage are formed, blower is set in upper channel.
The upper channel, lower passage at the construction face of service gallery structure up and down.
The beneficial effects of the utility model are mainly reflected in following aspects:
1, tunnel service gallery is separated by upper channel, lower passage by the form concrete partition of fixed setting,
Upper channel enters fresh air, and dirty gas is discharged in lower passage, and service gallery construction period is in same tunnel service gallery
Interior formation ventilation by ducts, solves that High aititude long distance tunnel forced ventilation difficulty is big, effect is poor and common laneway type
The problems such as ventilation scheme investment is larger；
2, form concrete partition has better airtight performance than previous color steel tile partition and difficulty of construction is lower, both
It ensure that the validity of service gallery construction ventilation, and reduce the time of diaphragm construction operation.
3, it can be discharged fume by upper channel during tunnel operation, lower passage evacuation personnel, realize signs of human habitation separation, will assist
Tunnel and Emergency Assistance station are integrated, and without rescue station is separately built again, improve the service efficiency of service gallery, and have
Conducive to reduction tunnel construction cost.

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to FIG. 1, FIG. 2 and FIG. 3, the High aititude railway tunnel auxiliary hole for taking into account construction, ventilation of taking precautions against natural calamities of the utility model
Road liner structure, including tunnel structure 10 and coupled logical service gallery structure 20.It is solid in the service gallery structure 20
Form concrete partition 21 is set surely, transverse ends and the service gallery structure 20 of form concrete partition 21 are connected as one,
And service gallery structure 20 is separated to form service gallery upper channel 22 and service gallery lower passage 23, upper channel 22
Interior setting blower 25.
Referring to FIG. 1, FIG. 2 and FIG. 3, the service gallery upper channel 22, service gallery lower passage 23 are in service gallery
At the construction face 24 of structure 20 up and down.In service gallery work progress, service gallery is excavated to construction face 24
Afterwards, concrete lining trolley applies the service gallery structure 20 and form concrete partition 21 at rear, form concrete partition
21 setting position should be calculated in advance by service gallery institute required airflow.Fresh wind is by 20 inlet blower of service gallery structure
25 are driven into service gallery upper channel 22, then reach construction 24 job position of face, then via service gallery lower part
Channel 23 is discharged into tunnel structure 10, to form an effective ventilation by ducts.
Referring to Fig. 4 and Fig. 5, service gallery plays the role of Emergency Assistance station during tunnel operation.After the condition of a disaster occurs, disaster
The pernicious gas of generation is spread in tunnel structure 10, and subsequent pernicious gas drives through blower 25 by service gallery upper channel 22
It discharges, staff in tunnel is then evacuated by service gallery lower passage 23 and gone out.
The above only explains through diagrams, and the utility model takes into account construction, the High aititude railway tunnel for ventilation of taking precautions against natural calamities assists
Some principles of tunnel liner structure are not intended to shown in being confined to the utility model and described specific structure and applicable model
