Abstract
The present invention provides the service channels between a kind of tunnel up and down, it is characterized by: it includes the first tunnel and the second tunnel being parallel to each other, first tunnel excavation has and its perpendicular the first lateral service channel for being connected to and extending to the second tunnel, second tunnel excavation, which has, to be connected with its perpendicular the second lateral service channel for being connected to and extending to the first tunnel, the first lateral service channel and the second lateral service channel by longitudinal direction fire escape.The present invention meets the escape stair gradient, shortens the duration, saves project cost.
Description
Technical field
The invention belongs to the field of engineering technology such as Urban Underground rail traffic, and in particular to the contact above and below a kind of between tunnel
Channel.
Background technique
To solve the problems, such as the fire prevention in tunnel and evacuating, the contact between connection tunnel is set according to a fixed spacing between two tunnels and is led to
Road.In existing engineering, when upper and lower tunnel vertical range is big, horizontal distance is small, and linear type transverse direction service channel is unsatisfactory for evacuation building
When terraced slope requirement, and use open cut vertical shaft.Since transit tunnel construction carries 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, project cost high and uncontrollable.
Summary of the invention
The purpose of the present invention is to the defects of the prior art, provide the service channel above and below a kind of between tunnel, meet
The escape stair gradient, shortens the duration, saves project cost.
The present invention provides the service channels between a kind of tunnel up and down, it is characterised in that: it includes first to be parallel to each other
Tunnel and the second tunnel, the first tunnel are located at the top in the second tunnel；First tunnel excavation has perpendicular to be connected to and to its
The first lateral service channel that two tunnels extend, the second tunnel excavation has perpendicular be connected to and to the of the extension of the first tunnel with its
Two lateral service channels, the first lateral service channel and the second lateral service channel are parallel to ground, the first lateral service channel
It is connected with the second lateral service channel by longitudinal fire escape.
The longitudinal direction fire escape is obliquely installed, the end phase of the upper end of longitudinal fire escape and the first lateral service channel
Connection；The lower end of longitudinal fire escape is connected with the end of the second lateral service channel.
The longitudinal direction fire escape is using ramp or the form of escape stair.
The end of described first lateral service channel extends and is raised in the second tunnel the first lateral service channel and indulges
To fire escape junction.
The end of described second lateral service channel extends and is raised in the first tunnel the second lateral service channel and indulges
To fire escape junction.
The present invention excavates service channel using subsurface excavation method, adapts to get in touch between overlapping tunnel closely, above and below big height difference logical
Road.The present invention is evacuated relative to vertical shaft folding step, and the one or two lateral service channel and longitudinal fire escape cooperatively form Z-type structure.Z
The evacuation of type inclined shaft, evacuation function substantially improve.The present invention effectively shortens the duration using subsurface excavation method, investment reduction, in Urban Underground
The fields such as rail traffic are with good application prospect.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the face 1-1 of the present invention cross-sectional view；
Wherein, the first tunnel 1-, the second tunnel 2-, the lateral service channel of 3- first, the lateral service channel of 4- second, 5- are vertical
To fire escape.
Specific embodiment
The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments, convenient for this hair is well understood
It is bright, but they limiting the invention.
As shown in Figure 1, the present invention provides the service channels between a kind of tunnel up and down, it is characterised in that: it includes mutual
Parallel the first tunnel 1 and the second tunnel 2,1 tunneling of the first tunnel have and its perpendicular for being connected to and extending to the second tunnel 2
One lateral service channel 3,2 tunneling of the second tunnel has laterally gets in touch with its perpendicular second for being connected to and extending to the first tunnel 1
Channel 4, the first lateral service channel 3 pass through longitudinal fire escape 5 with the second lateral service channel 4 and are connected.First laterally joins
Network channel 3 and the second lateral service channel 4 are parallel to the ground.First lateral service channel 3 and the second lateral service channel 4 with it is vertical
It matches to form Z-type inclined shaft to fire escape 5, adapts to short distance, big height difference overlapping tunnel up and down, dredged relative to vertical shaft folding step
It dissipates, effectively reduces the gradient of fire escape, evacuation function substantially improves, and shortens the construction period effectively save investment.
Described first lateral service channel 3 and the connection angle of 5 axis of longitudinal fire escape and the second lateral service channel 4
It is identical as the angle [alpha] of longitudinal 5 axis of fire escape to be not less than 90 °.
It is described longitudinal direction fire escape 5 using ramp form, longitudinal 5 axis of fire escape with perpendicular to 1 axis of the first tunnel
The angle of line plane is not more than 7 °.The longitudinal direction fire escape 5 is using the form of escape stair, and longitudinal 5 gradient of fire escape is not
Greater than 35 °.Longitudinal 5 length of fire escape is true according to the difference in height of the first lateral service channel 3 and the second lateral service channel 4
It is fixed, i.e. L=hcot β.
The end of the first lateral service channel 3 extends to the second tunnel 2 and is raised in the first lateral service channel 3 and
The end of second lateral service channel 4 described in longitudinal 5 junction of fire escape extends to the first tunnel 1 and is raised in second laterally
5 junction of service channel 4 and longitudinal fire escape；Guarantee the connective stability of longitudinal fire escape 5.
When construction, the first tunnel 1 is excavated first and the second tunnel 2 to hole is logical.Then supporting and excavation both ends first are lateral
Service channel 3 and the second lateral service channel 4, while pouring two lining structures.Supporting and the longitudinal fire escape 5 of excavation again, connection
After first lateral service channel 3 and the second lateral service channel 4, two lining structures are poured.
The content that this specification is not described in detail belongs to the prior art well known to professional and technical personnel in the field.
