Abstract
The utility model provides a contact passageway between upper and lower tunnel, its characterized in that: it is including the first tunnel and the second tunnel that are parallel to each other, and a no -dig tunnel has rather than perpendicular intercommunication mutually and the first horizontal contact passageway that extends to the second tunnel, and the 2nd no -dig tunnel has rather than feeding through perpendicularly mutually and transversely getting in touch with the passageway to the second of first tunnel extension, and first horizontal contact passageway and second are transversely got in touch with the passageway and be linked together through vertical evacuation passage. The utility model discloses satisfy the escape stair slope, shortened the time limit for a project, saved engineering cost.
Description
Technical field
This utility model belongs to the field of engineering technology such as Urban Underground track traffic, and in particular between a kind of upper and lower tunnel
Service channel.
Background technology
For solving the fire prevention in tunnel and evacuating problem, the contact arranged according to a determining deviation between two tunnels between UNICOM tunnel is led to
Road.In existing engineering, when upper and lower tunnel vertical dimension is big, horizontal range is little, and the horizontal service channel of linear type is unsatisfactory for evacuating building
During terraced slope requirement, and adopt open cut vertical shaft.As transit tunnel construction is carried out after the completion of Construction of Silo, and open cut vertical shaft is deposited
In house the problems such as pipeline removal, traffic data process, cause construction period length, construction costs high and uncontrollable.
Utility model content
The purpose of this utility model is aiming at the defect of prior art, there is provided the service channel between a kind of upper and lower tunnel,
Meet the escape stair gradient, shorten the duration, save construction costs.
This utility model provides the service channel between a kind of upper and lower tunnel, it is characterised in that：It includes what is be parallel to each other
First tunnel and the second tunnel, the first tunnel are located at the top in the second tunnel；First tunnel excavation is had and perpendicular is connected simultaneously with which
To the second tunnel extend the first horizontal service channel, the second tunnel excavation have with its it is perpendicular connect and to the first tunnel extension
The second horizontal service channel, parallel to ground, first laterally gets in touch with for the first horizontal service channel and the second horizontal service channel
Passage and the second horizontal service channel are connected by longitudinal fire escape.
Longitudinal fire escape is obliquely installed, the end phase of the upper end of longitudinal fire escape and the first horizontal service channel
Connection；The lower end of longitudinal fire escape is connected with the end of the second horizontal service channel.
Longitudinal fire escape is in the form of ramp or escape stair.
The end of the first horizontal service channel extends to the second tunnel and is raised in the first horizontal service channel and indulges
To fire escape junction.
The end of the second horizontal service channel extends to the first tunnel and is raised in the second horizontal service channel and indulges
To fire escape junction.
This utility model excavates service channel using subsurface excavation method, adapts to join closely, between the upper and lower overlapping tunnel of the big discrepancy in elevation
Network passage.This utility model is evacuated relative to vertical shaft folding step, and the one or two horizontal service channel cooperatively forms Z with longitudinal fire escape
Type structure.Z-type inclined shaft is evacuated, and is evacuated function and is substantially improved.This utility model adopts subsurface excavation method effective reduction of erection time, saves and throws
Money, has preferable application prospect in fields such as Urban Underground track traffics.
Description of the drawings
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model 1-1 faces sectional view；
Wherein, the first tunnels of 1-, the second tunnels of 2-, the first horizontal service channels of 3-, the second horizontal service channels of 4-, 5- are indulged
To fire escape.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is easy to be well understood to
This utility model, but they do not constitute restriction to this utility model.
As shown in figure 1, this utility model provides the service channel between a kind of upper and lower tunnel, it is characterised in that：It includes
The first tunnel 1 being parallel to each other and the second tunnel 2,1 tunneling of the first tunnel have and perpendicular connect and extend to the second tunnel 2 with which
The first horizontal service channel 3,2 tunneling of the second tunnel have with its it is perpendicular connect and to the first tunnel 1 extend it is second horizontal
Service channel 4, the first horizontal service channel 3 are connected by longitudinal fire escape 5 with the second horizontal service channel 4.First is horizontal
It is parallel to the ground to service channel 3 and the second horizontal service channel 4.First horizontal service channel 3 and the second horizontal service channel 4
Be engaged to form Z-type inclined shaft with longitudinal fire escape 5, adapt to closely, the upper and lower overlapping tunnel of the big discrepancy in elevation, relative to vertical shaft roll over
Ladder is evacuated, and effectively reduces the gradient of fire escape, is evacuated function and is substantially improved, and reduction of erection time effectively save investment.
The connection angle and the second horizontal service channel 4 of 5 axis of the first horizontal service channel 3 and longitudinal fire escape
It is identical with the angle [alpha] of 5 axis of longitudinal fire escape to be not less than 90 °.
Longitudinal fire escape 5 in the form of ramp, 5 axis of longitudinal fire escape with perpendicular to 1 axle of the first tunnel
The angle of line plane is not more than 7 °., in the form of escape stair, 5 gradient of longitudinal fire escape is or not longitudinal fire escape 5
More than 35 °.5 length of longitudinal fire escape is true with the difference in height of the second horizontal service channel 4 according to the first horizontal service channel 3
It is fixed, i.e. L=hcot β.
The end of the first horizontal service channel 3 extend to the second tunnel 2 and be raised in the first horizontal service channel 3 with
The end of the second horizontal service channel 4 described in 5 junction of longitudinal fire escape extends to the first tunnel 1 and to be raised in second horizontal
Service channel 4 and longitudinal 5 junction of fire escape；Ensure the connective stability of longitudinal fire escape 5.
During construction, the first tunnel 1 is excavated first and the second tunnel 2 to hole is logical.Then supporting and excavation two ends first are horizontal
Service channel 3 and the second horizontal service channel 4, while pour two lining structures.Supporting and the longitudinal fire escape 5 of excavation, connect again
After first horizontal service channel 3 and the second horizontal service channel 4, two lining structures are poured.
The content that this specification is not described in detail belongs to prior art known to professional and technical personnel in the field.
