Description
Technical field
The present invention relates to a kind of shield tunnel segment lining structures.
Background technology
With the continuous improvement of mechanization degree and manufacturing industry level, Shield Construction Technique has because of it to ground disturbance
Small, environment influences the advantages such as small, speed of application is fast, has been increasingly becoming the main side that the underground engineerings such as urban subway are built
Method.Shield-bored tunnels are mostly double track tunnel, usually the parallel tunnel of left and right line.But under special geologic condition, for evacuation
Certain underground structures, structures, bi-directional subway tunnel can take the overlapping shield tunnel of upper and lower separate type.This overlapping up and down
Shield tunnel is upper and lower two tunnel structures for forming separation one after another by shield machine digging excavation, segment assembly.Such as Shenzhen
Line 2 Metro, No. 3 lines, No. 5 lines of Guangzhou Track Traffic etc. due to the limitation of various conditions and Subway Tunnel partially or fully
Take the overlapping shield tunnel of this separate type up and down.
Upper and lower separate type overlapping shield tunnel usually has the characteristics that overlapping clear distance is small, overlap distance is long, sequence of construction
For：Offline tunnel takes the lead in, and tunneling shield of reaching the standard grade tunnels driving → interlayer Stabilizing Grout → offline tunnel frame support is protected →
→ tunnel grouting of reaching the standard grade is reinforced.There are many engineering challenges and drawbacks in process of construction for the overlapping shield tunnel of separate type：(1)
Additional stress can be generated in tunnel excavating process to offline tunnel by reaching the standard grade, so as to cause offline tunnel deformation；(2) tunnel of reaching the standard grade is applied
Unloading effect after work may cause offline tunnel to swell；(3) speed of offline tunnel frame support and tunnel of reaching the standard grade
Assembled speed must match, and otherwise will cause tunnel deformation；(4) vertical height of work progress is big, to stratum and top-out
Object is affected, and Land-Subsidence Control is difficult.
Invention content
The goal of the invention of the present invention is to provide a kind of integral type shield tunnel segment lining structure up and down, one about this kind
Formula shield tunnel segment lining structure, globality is strong, intensity is high, and bearing capacity is good, can effectively control surface subsidence, ensure periphery
The safety of construction of structures and its difficulty of construction reduce, construction efficiency improves.
The technical scheme adopted by the invention for realizing the object of the invention is a kind of integral type shield tunnel segment lining up and down
Structure, including top tunnel and lower part tunnel, it is characterised in that：The top tunnel and lower part tunnel constitute " 8 " font
Integral type shield tunnel segment lining structure, specific constitute are：
Multiple circumferential assembled top tunneltron loops for forming major arc shapes of arc-shaped upper tube piece, it is multiple it is arc-shaped under
The circumferential assembled lower part tunneltron loop for forming major arc shape in portion section of jurisdiction；Top tunneltron loop and lower part tunneltron loop pass throughThe abnormity connection pipe sheet assembling of shape forms the structure ring of " 8 " font；Longitudinal assembly forms " 8 " font to multiple structure rings again
Integral type shield tunnel segment lining；Structure more than abnormity connection section of jurisdiction is top tunnel, under structure below is
Portion tunnel.
Compared with prior art, the beneficial effects of the invention are as follows：
One, integral type shield tunnel segment lining structure of the invention, eliminates the overlapping shield tunnel up and down of separate type
Interlayer soil between structure, globality is stronger, and structure is more stable, secured, can more effectively control surface subsidence, ensure periphery
The safety of construction of structures.
Two, after disposably being excavated by large-scale shield machine, disposable assembled forming can be obtained the upper next of the present invention
Body formula shield tunnel construction reduces disturbance of the construction to stratum, the shadow constructed to stratum compared with excavation twice, twice assembly
Sound is smaller, also can preferably control surface subsidence.
Three, it once excavates, is primary assembled compared with excavation twice, twice assembly, also significantly improving construction efficiency.And
And integral type shield tunnel construction up and down of the invention, need not be arranged and remove offline tunnel holder support etc. construction journey
Sequence further improves construction efficiency.
Further, the left side, the right of abnormity connection of the invention section of jurisdiction be isometric but end not in the same horizontal line；The left side
The high abnormity connection section of jurisdiction in end is left high special-shaped connection section of jurisdiction, by the right height of left high 180 ° of special-shaped connection section of jurisdiction left rotation and right rotation
Abnormity connection section of jurisdiction；When multiple structure ring assembly, left high abnormity connection section of jurisdiction and right high abnormity connection section of jurisdiction are used alternatingly.
In this way, realizing the staggered joint erection of section of jurisdiction seam between structure ring, the longitudinal rigidity of tunnel structure is improved, it can be more effective
Control tunnel differential settlement；Meanwhile the staggered joint erection of section of jurisdiction seam, also reduce the deflection of liner structure, seam is more
It is close to, the water resistance of entire pipe-plate lining structure can be improved.
Further, lower part section of jurisdiction thickness of the invention is 1.5-2 times of top section of jurisdiction thickness.The circumferential assembly of upper tube piece
Connector is 3 curved bolts, and the circumferential assembled connector of lower tube piece is 5 curved bolts.
The intensity in the high lower part tunnel of bearing requirements is strengthened in this way, can ensure the carrying energy of entire tunnel structure well
Power and safety, while reducing the intensity in the lower top tunnel of bearing requirements and with material, the economy for meeting constructing tunnel is wanted
It asks.
Further, top section of jurisdiction of the invention and lower part section of jurisdiction are 5, the radian of each top section of jurisdiction or lower part section of jurisdiction
It is 44 °.
Section of jurisdiction size in this way is suitable, has both facilitated the prefabricated of section of jurisdiction and transport, while the assembled workload of section of jurisdiction is also smaller, applies
Work is efficient.
Further, the longitudinal assembled connector of multiple structure rings of the invention is bolt.
In such manner, it is possible to more convenient and quicker realize longitudinal assembled connection between structure ring.
Further, top tunneltron loop of the invention and lower part tunneltron loop pass throughThe special-shaped connecting tube of shape
The concrete structure of structure ring that piece assembly forms " 8 " font is：The left upper end and upper right side of abnormity connection section of jurisdiction are curved by 3
Bolt is connect with top tunneltron loop；The lower-left end of abnormity connection section of jurisdiction and bottom righthand side pass through 5 curved bolts and lower part tunnel
Deferent loop connects.
It can ensure the bearing capacity in lower part tunnel in this way, meanwhile, construction and the materials in top tunnel are reduced, tunnel is taken into account
The safety of structure and economy.
Further, the left side, the right of abnormity connection of the invention section of jurisdiction stay that there are two lateral injected holes.
In this way, after the completion of tunnel-liner assembly, it can be by injected hole to native around the connecting portion in upper and lower tunnel
Body carries out grouting and reinforcing, further increases the integral strength and bearing capacity of tunnel structure.
Present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments
