Description
Technical field
The present invention relates to a kind of tunnel-liner technical fields, and in particular to a kind of shield tunnel liner ring.
Background technology
The section of jurisdiction partitioned mode of tunnel-liner needs to consider the weight of every piece of section of jurisdiction, assembled convenience, and entire
The factors such as the mechanical characteristics of Lining Ring, longitudinally connected rigidity and tunnel curve condition.Therefore for large diameter shield tunnel,
It is fitted and is required according to tunnel, rational block count and the section of jurisdiction angle that binds can effectively reduce assembled difficulty；Rational longitudinal direction spiral shell
The erection method and the fissure of displacement lap of splice etc. of bolt number and staggered joint erection can effectively improve longitudinal rigidity, to improve tunnel
Shock resistance, increase resist differential settlement ability etc..
What is be commonly used is a kind of shield shield tunnel liner ring of 7+1 partitioned modes, it is spliced by eight pieces of sections of jurisdiction
It forms.Two kinds of sides of 1/2 staggered joint erection of circumferential overlap joint and 1/4 staggered joint erection of circumferential overlap joint may be used in the Lining Ring when in use
Formula, but there is problem in two ways：When using 1/2 staggered joint erection of circumferential overlap joint, on the one hand, since local longitudinal joint is logical
Seam, weakens the rigidity of structure of Lining Ring, and be unfavorable for seam waterproof；On the other hand, using the partitioned mode in straightway tunnel
More complex combination must be used to be fitted when road assembly, be unfavorable for the assembly of straightway shield tunnel liner ring.When using ring
When to 1/4 staggered joint erection of overlap joint, on the one hand, the interannular fissure of displacement lap of splice is smaller, is unfavorable for the transmission of interannular shearing and moment of flexure；Separately
On the one hand, when shield driving jack is arranged in pairs in construction, driving jack will act on longitudinal seam, cause stress collection
In, it easily leads to section of jurisdiction and is destroyed.
Invention content
It is an object of the invention in view of the drawbacks of the prior art, provide a kind of globality and water proofing property improving structure
The shield tunnel liner ring of energy.
Particularly, the present invention provides a kind of shield tunnel liner ring, by one piece of section of jurisdiction of binding, two pieces respectively with it is described
Bind section of jurisdiction two outside connect adjoining section of jurisdiction, two adjoining sections of jurisdiction between three pieces of standard sections of jurisdiction successively ring dress rearrange,
The corresponding central angle in the section of jurisdiction of binding is 22.5 °, and the corresponding central angle in the adjacent section of jurisdiction is 68.5 °, the standard pipe
The corresponding central angle of piece is 67 °；Spliced using the fissure of displacement between each section of jurisdiction in the Lining Ring, and each Lining Ring
Bolt and its auxiliary connection, 12 sets of longitudinal joint connection bolts and its auxiliary connection are connected using 16 sets of circumferential welds；The Lining Ring is set along longitudinal direction
There are longitudinal bolt, the circumferential weld connection bolt and its auxiliary connection by a circumferential connection bolt, two circumferential nuts, two circumferential directions
Washer forms, and the longitudinal joint connection bolt and its auxiliary connection include a longitudinally connected bolt, two longitudinal nuts, two longitudinal directions
Washer forms, and the circumferential connection bolt, longitudinally connected bolt, circumferential nut, longitudinal nut, circumferential washer, longitudinal washer are equal
