Description
Technical field
The utility model is related to subway engineering technical field, is more specifically a kind of zigzag service channel structure.
Background technology
Service channel is the passage OR gate hole of two driving running tunnels of the same circuit up-downgoing of connection, in train in interval
When meeting disaster, the forced shutdowns such as fire, used for passenger from accident tunnel to the evacuation of zero defects tunnel safety.
According to《Metro design code》(GB50157-2013), two single track line tunnels should set service channel, adjacent two
The distance between individual service channel not should be greater than 600m；Interval drainage pumping plant should be with interval service channel or middle wind when having ready conditions
Well is built jointly.
Transverse passage-way is set between up-downgoing tunnel, the common practices of service channel is belonged to using Mining Method boring construction.
With the fast development of metro construction, track traffic underground terminal station, circuit are more and more.Newly-built circuit
It is notable all the more by surrounding enviroment restraining factors, there is increasing superimposing thread or the up-downgoing running tunnel of the big discrepancy in elevation.For example it is military
No. 7 line first stage of the project Hong Kong way stations of Chinese track traffic~tri- are positive, and way station is interval.
For ease of evacuating personnel, service channel is built between big discrepancy in elevation up-downgoing running tunnel, stair need to be set.According to
《Civil buildings design general rule》(GB50352-2005), the depth-width ratio of stair step should meet width >=0.26m, highly≤
0.17m.Often subway up-downgoing tunnel level interval is not too large, and this is resulted in sets between big discrepancy in elevation up-downgoing running tunnel
Putting service channel can not be using conventional transverse passage-way mode.
The structure that connection up-downgoing running tunnel is performed in open cut vertical shaft, vertical shaft is performed on ground, it is possible to achieve big high
Service channel is built between poor up-downgoing running tunnel.But city strategic road or intensive building are worn under subway tunnel major part
Group, by ground environment conditionality, it is difficult to perform open cut vertical shaft on ground.Such as No. 7 line first stage of the project of Wuhan rail transit are fragrant
Port way station~tri- are positive, and way station is interval.The interval from Hong Kong way station by up and down in the way of overlapping tunnel it is outbound, circuit is with R=340m's
Major trunk roads Ao Menlu is reached behind several 1~6 floor house such as curve Xia Chuan General Hospital of Yangtze River Shipping, does not possess ground construction open cut and erects
The condition of interval service channel is built after well.
The content of the invention
The purpose of this utility model is the weak point for overcoming above-mentioned background technology, and proposes that a kind of zigzag contact is logical
Road structure.
What the technical solution of the utility model was implemented by following measure：A kind of zigzag service channel structure, in subway
Up-downgoing tunnel is provided with the left plug-in transverse passage-way in threaded list road and the right plug-in transverse passage-way in threaded list road, the left plug-in transverse passage-way in threaded list road and the right side
By bell-mouthed connection between the plug-in transverse passage-way in threaded list road and tunnel,
Connected between the described left plug-in transverse passage-way in threaded list road and the right plug-in transverse passage-way in threaded list road by access ramp,
The described left plug-in transverse passage-way in threaded list road and the right plug-in transverse passage-way in threaded list road set movement joint respectively with tunnel junction,
The described left plug-in transverse passage-way in threaded list road and the right plug-in transverse passage-way in threaded list road are provided with portal with described access ramp junction
Ring beam.
In the above-mentioned technical solutions：The bottom of the described right plug-in transverse passage-way in threaded list road is provided with draining pump house.
In the above-mentioned technical solutions：The described left plug-in transverse passage-way in threaded list road, the right plug-in transverse passage-way in threaded list road and access ramp
Use stalk crowned section structure.
The utility model has following technological merit：When the 1st, solving the unconditional construction shaft in ground, big discrepancy in elevation up-downgoing
The problem of service channel can not be built between running tunnel.
2nd, using Mining Method boring construction, more traditional ground construction vertical shaft, the interior construction service channel structure of vertical shaft is big
It is big to reduce investment, shorten the duration, reduce the influence to surrounding enviroment.
3rd, passage and tunnel junction set movement joint, substantially reduce Freezing Method for Cross-passage Construction phase and operation phase up-downgoing tunnel
Influencing each other between road.
Brief description of the drawings
Fig. 1 is structural plan figure of the present utility model.
Fig. 2 is section of structure of the present utility model.
In figure：The left plug-in transverse passage-way 1 in threaded list road, the plug-in transverse passage-way 2 in right threaded list road, access ramp 3, draining pump house 4, movement joint
