Description

Upper and lower integral type shield tunnel segment lining structure
Technical field
The present invention relates to a kind of shield tunnel segment lining structure.
Background technology
With the continuous improvement of mechanization degree and manufacturing industry level, Shield Construction Technique has to ground disturbance because of which The advantage such as little, environmental effect is little, 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 mostly are double track tunnel, usually the parallel tunnel of left and right line.But under special geologic condition, it is avoidance Some underground structures, structures, bi-directional subway tunnel can take the overlapping shield tunnel of upper and lower separate type.This overlap up and down Shield tunnel is to form detached upper and lower two tunnel structures one after another by shield machine digging excavation, segment assembly.As Shenzhen Line 2 Metro, No. 3 lines, No. 5 lines of Guangzhou Track Traffic etc. all due to various conditions restriction and in Subway Tunnel partially or fully Take the overlapping shield tunnel of this upper and lower separate type.
Separate type overlapping shield tunnel generally has the features such as overlap clear distance is little, overlap distance is long, its sequence of construction up and down For:The offline tunnel driving → interlayer Stabilizing Grout → offline tunnel frame that takes the lead in is supported and protects → reach the standard grade tunneling shield to tunnel → tunnel grouting of reaching the standard grade is reinforced.There is many engineering challenges and drawback in process of construction in the overlapping shield tunnel of separate type:(1) Reach the standard grade in tunnel excavating process and additional stress can be produced to offline tunnel, 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) offline tunnel frame is supported speed and tunnel of reaching the standard grade Assembled speed must be mated, and will otherwise cause tunnel deformation;(4) vertical height of work progress is big, to stratum and top-out The impact of thing is larger, Land-Subsidence Control difficulty.
Content of the invention
The goal of the invention of the present invention is to provide a kind of upper and lower integral type shield tunnel segment lining structure, one about this kind Formula shield tunnel segment lining structure, globality is strong, intensity is high, and bearing capacity is good, can effective control surface subsidence, guarantee periphery Safe and its difficulty of construction of construction of structures reduces, efficiency of construction is improved.
The technical scheme adopted by the invention for realizing the object of the invention is, a kind of upper and lower integral type shield tunnel segment lining Structure, including top tunnel and bottom tunnel, it is characterised in that:Described top tunnel and bottom tunnel constitute " 8 " font Integral type shield tunnel segment lining structure, which is specifically constituted is:
The assembled top tunneltron loop for forming major arc shape of the upper tube piece ring of multiple circular arcs, under multiple circular arcs The assembled bottom tunneltron loop for forming major arc shape of portion section of jurisdiction ring;Top tunneltron loop and bottom tunneltron loop pass throughThe abnormity connection pipe sheet assembling of shape forms the structure ring of " 8 " font;Longitudinal direction 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 following structure is Portion tunnel.
Compared with prior art, the invention has the beneficial effects as follows:
First, the integral type shield tunnel segment lining structure of the present invention, eliminates the overlapping shield tunnel up and down of separate type Interlayer soil between structure, its globality is higher, and structure is more stable, firm, can more effectively control surface subsidence, ensure periphery The safety of construction of structures.
2nd, after large-scale shield machine is disposably excavated, disposable assembled shaping can obtain the upper next of the present invention Body formula shield tunnel construction, than excavation twice, twice assembly, reduces disturbance of the construction to stratum, the shadow that constructs to stratum Sound is less, can also better control over surface subsidence.
3rd, once excavate, once assembled than excavating twice, assembled twice, also significantly improve efficiency of construction.And And, the integral type shield tunnel construction up and down of the present invention, it is not necessary to arrange and remove the construction journey such as the support support in offline tunnel Sequence, further increases efficiency of construction.
Further, the abnormity of the present invention connects the left side of section of jurisdiction, the isometric but end in the right not in the same horizontal line;The left side The high abnormity connection section of jurisdiction in end is left high abnormity connection section of jurisdiction, by 180 ° of left high abnormity connection section of jurisdiction left rotation and right rotation right height Abnormity connection section of jurisdiction;During multiple structure ring assembly, left high abnormity connection section of jurisdiction and right high abnormity connection section of jurisdiction are used alternatingly.
So, the staggered joint erection of section of jurisdiction seam is realized between structure ring, improves the longitudinal rigidity of tunnel structure, 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 whole pipe-plate lining structure can be improved.
Further, the bottom section of jurisdiction thickness of the present invention is 1.5-2 times of top section of jurisdiction thickness.The assembly of upper tube piece ring Connector is 3 curved bolts, and the connector of lower tube piece ring assembly is 5 curved bolts.
The intensity in the high bottom tunnel of bearing requirements is so strengthened, the carrying energy of whole tunnel structure can be ensured well Power and safety, while reducing the intensity in the relatively low top tunnel of bearing requirements and using material, the economy for meeting constructing tunnel will Ask.
Further, the top section of jurisdiction of the present invention and bottom section of jurisdiction are 5, the radian of each top section of jurisdiction or bottom section of jurisdiction It is 44 °.
So section of jurisdiction size is suitable, had both facilitated the prefabricated of section of jurisdiction and transport, and while the assembled workload of section of jurisdiction is also less, had applied Work efficiency high.
Further, the assembled connector in multiple structure rings longitudinal direction of the present invention is latch.
In such manner, it is possible to more convenient and quicker realize the assembled connection in longitudinal direction between structure ring.
Further, the top tunneltron loop of the present invention and bottom tunneltron loop pass throughThe special-shaped connecting tube of shape The concrete structure of the assembled structure ring for forming " 8 " font of piece is:The left upper end of abnormity connection section of jurisdiction and upper right side are all curved by 3 Bolt is connected with top tunneltron loop;The lower-left end of abnormity connection section of jurisdiction and bottom righthand side are all by 5 curved bolts and bottom tunnel Deferent loop connects.
The bearing capacity in bottom tunnel so ensure that, meanwhile, reduce construction and the materials in top tunnel, take into account tunnel The safety of structure and economy.
Further, two horizontal injected holes are all left on the left side of the abnormity connection section of jurisdiction of the present invention, the right.
So, after the completion of tunnel-liner assembly, injected hole can be passed through to soil around the connecting portion in upper and lower tunnel Body carries out grouting and reinforcing, improves bulk strength and the bearing capacity of tunnel structure further.
The present invention is described in further detail with reference to the accompanying drawings and detailed description
