Description
Technical field
The utility model belongs to tunnel duct piece attachment structure field, is indulged more particularly, to one kind suitable for tunnel duct piece
The attachment structure of seam and section of jurisdiction ring and tunnel-liner.
Background technology
Duct pieces of shield tunnel ring and longitudinal seam generally use the side of installation bolt after first assembly in engineering at present
Formula is attached.The modes (as shown in Figure 1) such as curved bolt 4, oblique bolt 5, short straight bolt 6 can be divided into according to bolt type difference,
But regardless of bolt connecting mode, it is both needed to set hand hole 3, and during bolt use, it is curved in the case of large eccentric pressuring
Square, axle power synergy can cause segment joint to open.Opened by structure exemplified by by hogging moment, on the outside of segment joint bolt by
Draw, concrete surface is pressurized on the inside of seam, and seam is in stable state.Bolt can meet that the use of engineering will in general
Ask, but in soft soil layer or larger lining cutting annular strain, then problems be present：1) when lining cutting annular strain is larger, in moment M
In the presence of segment joint joint open θ increases, the stress F of bolt can increase, and the compression stress ot of concrete can be caused to increase, when
When this trend continues increase, compressive region concrete stress σ can exceed that the compression strength of concrete material, cause section of jurisdiction 1 broken
Damage (as shown in Figure 2)；2) connected mode of bolt is used, such as ring bolt 10 and longitudinal bolt 11 are set, it must set
Hand hole (i.e. the holes of construction bolts) is put, the presence of hand hole can weaken tunnel segment structure, and hand hole is located at close seaming position, especially
It is circumferential weld and the close section of jurisdiction corner of longitudinal joint connecting bolt, weakening the influence for hand hole will be superimposed, concrete compression at abutment joint
Significant adverse effect (as shown in Fig. 3) is produced, its weakening to structure is bigger if using short straight bolt.
In order to improve the rigidity of seam crossing, some existing improved technologies provide following method：Carried for example, leaf builds loyalty etc.
Having gone out " a kind of city underground overlapping shield tunnel tunnel segment structure using special longitudinal connecting member ", (utility application is public
The A of announcement CN 104790974), the technology is mainly to be distributed some steel fastener and steel necks in the circumferential weld connection of section of jurisdiction, is led to
Cross after steel fastener longitudinally is pushed into steel neck, then circumferentially rotation section of jurisdiction makes steel fastener buckle into steel neck, and use latch
Cavity is filled after fixation.The technology improves the longitudinally connected rigidity between the circumferential weld of section of jurisdiction in practical engineering application, in overlapping tunnel
It can be reduced to stratum consolidation in road design, reduce influencing each other between tunnel；For another example, Xiao Mingqing etc. proposes " a kind of circular
Rebate type duct pieces of shield tunnel interannular shear structure " (B of utility model patent Authorization Notice No. CN 103924983), the skill
Art, along several circular rebates are distributed, the shearing resistance energy between the circumferential weld of section of jurisdiction is improved by tenon structure mainly between the circumferential weld of section of jurisdiction
Power, improve load and local stress of the existing concavo-convex tenon structure in practicality, can effectively reduce local concrete and be broken
Bad possibility.
Above-mentioned prior art efficiently solves certain engineering problem in practical engineering application, particularly to section of jurisdiction ring
Circumferential weld (i.e. longitudinally connected) rigidity improves and serves obvious effect between ring, and its essence is to circumferential weld (i.e. longitudinally connected)
A kind of reinforcement measure of the rigidity of structure, also fail to substitute the effect of bolt, it is still desirable to it is connected by screw bolts, and on section of jurisdiction
Reserved bolt hand hole, inevitably result in the structure at segment joint and weaken, and above-mentioned similar tenon groove structure and in fact
The mode of applying can not directly use longitudinal joint (i.e. ring connects), and the longitudinal joint (i.e. ring connects) of section of jurisdiction still uses in the prior art
Bolt connection, it, which still exists, weakens tunnel segment structure, and local stress is bigger than normal, and then the problem of cause section of jurisdiction to be destroyed.
