Description
Technical field
The utility model belongs to rail traffic technical field of construction, and in particular to a kind of rail based on subway station list branch-cut bridge
Arrange well system.
Background technique
With the continuous quickening of Urbanization in China, more and more city track traffic engineerings are designed, are built
If.In urban track traffic, subway is a kind of highly important traffic form, since it often runs in underground, is not take up
Ground traffic space, and freight volume is big, punctuality rate is high, can alleviate the traffic jam issue in city well, thus obtained wide
General application.
In the process of construction of subway, the basic setup of subway station section is in underground, for the paving for guaranteeing subway train track
If it is required that generally requiring to lift well/hole, i.e., commonly called section of track well in the reserved setting track in the station of open cut.Section of track well
Function be usually that lifting is provided for section of track finished product to the channel of track-laying vehicle, size, position need to meet that the section of track is safe and efficient to be hung
The requirement of dress.Under normal circumstances, the single-unit length of underground railway track is 25m, this makes the size of section of track well often cannot be less than growing
Spend 27m, width 4.5m.
In the prior art, section of track well opens up often as shown in Fig. 4~5, wherein section of track well is often provided with driving
The top of line, and station bottom plate is opened to always from station top plate, so that the section of track can be directly from station top plate upper lifting to vehicle
On the lane stood on bottom plate, then operation of laying a railway track carried out by track-laying vehicle.Although above structure can realize section of track well to a certain extent
Function, complete the lifting of the section of track；But be not difficult to find out from Fig. 5, form is arranged in existing section of track well, since it directly sets
It sets above lane AT STATION, causes the station side wall in section of track well length range to be in cantilever position always, cantilever height is past
Toward more than 10m, this is seriously impaired the rigidity of structure of station side wall, and there are great security risks, to station structure
Safety, stability adversely affect.
For the safety for guaranteeing station structure, traditional way often uses fender post/wall+anchor cable form, or will
Building enclosure within the scope of section of track well opening is done in the arc-shaped.But the use of anchor cable scheme, which often exists, influences peripheral ring
The problem of border, thus forbid using this kind of setting form in urban area in many cities；Although arc-shaped building enclosure energy
The safety problem of section of track well side station side wall is solved to a certain extent, but it often takes up an area greatly, setup cost is high, in city
Using being limited, there are biggish limitation, it is unable to fully meet the setting needs of all kinds of subway station section of track wells.Therefore, it needs
The new section of track well system of one kind is found or designed to meet its needs of constructing.

Iron walks the structural column 4 between line 3, is preferably arranged along the direction of travel interval of single branch-cut bridge 6, as shown in fig. 1, is arranged in this way
It not only can guarantee the structural stability of subway station, moreover it is possible to fully ensure that the setting of structural column 4 does not cause to do to the traveling of subway
It relates to.
In consideration of it, the top at single 6 middle part of branch-cut bridge is arranged in the section of track well 1 in preferred embodiment, correspondence, which is provided with, is singly crossed
The surface of line 6, and the length direction of section of track well 1 is along the direction of travel setting of single branch-cut bridge 6, specifically, top plate 7, vehicle AT STATION
Stand it is corresponding on plate 8 offer through upper and lower rectangular through holes, form section of track well construction, opening up for section of track well construction just may be used
Using the structural column 4 being set in station top plate 7 and station between plate 8, in station between plate 8 and station bottom plate 9, using it as rail
It arranges well construction and carries out structural support, then the section of track, which can be corresponded to, is lifted by section of track well 1 to the track-laying vehicle in single branch-cut bridge 6, thus
Complete the lifting of the section of track.
When section of track well 1 is arranged in the list branch-cut bridge of subway station, due to two lateral edge list branch-cut bridges 6 of single 6 medium position of branch-cut bridge
Direction of travel is provided with structural column 4, and structural rail 10 is often provided between adjacent structure column 4, as shown in fig. 1, that is, ties
Structure stringer 10 is correspondingly arranged in top plate 7 AT STATION or station on the bottom surface of plate 8, each structural column 4 is correspondingly connected with into unified
Beaer realizes the stabilization stress of subway station；Therefore, when section of track well 1 is arranged above single 6 middle part of branch-cut bridge in subway station,
The length direction of section of track well 1 is just parallel to the setting direction of 1 structure on two sides stringer 10 of section of track well, i.e. section of track well 1 opens up position
Support can just be carried out by the structural column 4 of 1 two sides of section of track well；Certainly, if quantity is arranged in the structural column 4 of 1 side of section of track well
When less, as shown in fig. 1, several interim columns 5 can be correspondingly arranged in the side, the section of track can be further preferably arranged in interim column 5
The corner location of well 1, be arranged such can sufficiently meet station top plate 7 after section of track well 1 is arranged, in station plate 8 structure safety, again
The safety of structure of the station side wall 2 of 3 side of line is walked without having to worry about subway, so that the function of section of track well has been preferably realized, it is complete
At the laying of subway rail row, the stability and safety of Metro Station Structure ensure that.
It is further preferred that it is provided with interim beam 11 between adjacent two interim column 5 in the setting of interim column 5, it is each to guarantee
Interim column 5 can be correspondingly connected with into unified beaer, and interim beam 11 is preferably correspondingly connected on side wall 2 AT STATION, as shown in figure 1 institute
Show；It is further preferred that being preferably arranged between the adjacent structural column 4 in single 6 two sides of branch-cut bridge after the closing of the hole of section of track well 1
After make structural rail 12, after make structural rail 12 and preferably have setting on the bottom surface of plate 8 in top plate 7 and station AT STATION, to protect
Demonstrate,prove the structural stability of 1 enclosed construction of section of track well.
The section of track well system based on subway station list branch-cut bridge in the preferred embodiment in the utility model, structure is simple, if
Simplicity is set, section of track well is preferably provided at the top of subway station list branch-cut bridge 6, so that opening up for section of track well 1 will not be to station side wall 2
Structural stability impact, reduce the generation of a wide range of cantilever situation of station side wall 2, ensure that station side wall 2
Structural stability and safety, it is ensured that the safety of subway station, and can be by subway during section of track well 1 is opened up
The existing structural column 4 in station is supported, and is reduced the setting of interim column 5, interim beam 11, is effectively reduced the waste of material,
The construction cost of section of track well system has been saved, and has ensured the stability of structure, there is biggish application value.
As it will be easily appreciated by one skilled in the art that the above is only the preferred embodiment of the utility model only, not
To limit the utility model, any modification made within the spirit and principle of the present invention, equivalent replacement and change
Into etc., it should be included within the scope of protection of this utility model.
