Abstract
The utility model provides a kind of Lining Ring, by three pieces of standard sections of jurisdiction between one piece of section of jurisdiction of binding, two pieces of adjoining sections of jurisdiction being connect respectively with two outsides of the section of jurisdiction of binding, two adjoining sections of jurisdiction, ring dress rearranges successively for it, the corresponding central angle in the section of jurisdiction of binding is 22.5 °, the corresponding central angle in the adjacent section of jurisdiction is 68.5 °, and the corresponding central angle in the standard section of jurisdiction is 67 °；The Lining Ring is equipped with longitudinal bolt along longitudinal direction.This case meets the complete staggered joint erection between ring and ring, and the central angle configuration of each ring is reasonable, improves the globality and water resistance of structure.
Description
Technical field
The utility model is related to a kind of tunnel-liner technical fields, and in particular to a kind of Lining 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 lining ring of 7+1 partitioned modes, it is spliced by eight pieces of sections of jurisdiction.The lining
It builds ring and 1/4 staggered joint erection two ways of 1/2 staggered joint erection of circumferential overlap joint and circumferential overlap joint, but two kinds of sides may be used when in use
There is problem in formula：When using 1/2 staggered joint erection of circumferential overlap joint, on the one hand, since local longitudinal joint is straight joint, weaken lining cutting
The rigidity of structure of ring, and it is unfavorable for seam waterproof；On the other hand, it must be used in the assembly of straightway tunnel using the partitioned mode
More complex combination fitting, is unfavorable for the assembly of straightway Lining Ring.When using 1/4 staggered joint erection of circumferential overlap joint, one
Aspect, the interannular fissure of displacement lap of splice is smaller, is unfavorable for the transmission of interannular shearing and moment of flexure；On the other hand, shield driving in construction
When jack is arranged in pairs, driving jack will act on longitudinal seam, causes stress concentration, easily leads to section of jurisdiction and be destroyed.
Utility model content
One purpose of the utility model is in view of the drawbacks of the prior art, to provide a kind of globality improving structure and anti-
The Lining Ring of aqueous energy.
Particularly, the utility model provides a kind of Lining Ring, is bound respectively with described by one piece of section of jurisdiction of binding, two pieces
Ring dress rearranges three pieces of standard sections of jurisdiction on the outside of the two of section of jurisdiction between the adjoining section of jurisdiction of connection, two adjoining sections of jurisdiction successively, described
The corresponding central angle in section of jurisdiction that binds is 22.5 °, and the corresponding central angle in the adjacent section of jurisdiction is 68.5 °, the standard section of jurisdiction pair
The central angle answered is 67 °；The Lining Ring is equipped with longitudinal bolt along longitudinal direction.
Further, spliced using the fissure of displacement between each section of jurisdiction in the Lining Ring, and each Lining Ring uses
16 sets of circumferential weld connection bolts and its auxiliary connection, 12 sets of longitudinal joint connection bolts and its auxiliary connection.
Further, the circumferential weld connection bolt and its auxiliary connection are by a circumferential connection bolt, two circumferential nuts, two
Only circumferential washer composition.
Further, longitudinal joint connection bolt and its auxiliary connection include a longitudinally connected bolt, two longitudinal nuts,
Two longitudinal washer compositions.
This case meets the complete staggered joint erection between ring and ring, and the central angle configuration of each ring is reasonable, improves structure
Globality and water resistance.
According to the accompanying drawings to the detailed description of the utility model specific embodiment, those skilled in the art will be more
Add the above-mentioned and other purposes, advantages and features of clear the utility model.
Description of the drawings
Some specific realities of the utility model are described in detail by way of example rather than limitation with reference to the accompanying drawings hereinafter
Apply example.Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing：
Fig. 1 is the structural schematic diagram of the Lining Ring of one embodiment of the utility model.
Fig. 2 is the structural schematic diagram of the adjoining section of jurisdiction in the Lining Ring of one embodiment of the utility model.
Specific implementation mode
Fig. 1-2 is a kind of Lining Ring of one embodiment of the utility model and adjacent section of jurisdiction therein, a kind of Lining Ring, by
One piece of adjoining section of jurisdiction 2, two that 1, two piece of section of jurisdiction is connect with two outsides of the section of jurisdiction 1 of binding respectively of binding abuts between section of jurisdiction 2
Three pieces of standard sections of jurisdiction 3 successively ring dress rearrange, it is described bind 1 corresponding central angle of section of jurisdiction be 22.5 °, the adjacent section of jurisdiction
2 corresponding central angles are 68.5 °, and 3 corresponding central angle of the standard section of jurisdiction is 67 °；The Lining Ring is equipped with along longitudinal direction
Longitudinal bolt.
When assembled, section of jurisdiction 1 of binding first overlaps 700mm and radially pushes to, and is then longitudinally inserted into, which can realize good
Good staggered joint erection.This case meets the complete staggered joint erection between ring and ring, and each joyous central angle configuration is reasonable, improves
The globality and water resistance of structure.
Spliced using the fissure of displacement between each section of jurisdiction in Lining Ring, and each Lining Ring connects spiral shell using 16 sets of circumferential welds
5,12 sets of longitudinal joint connection bolts of bolt and its auxiliary connection and its auxiliary connection 4, amount to 28 sets of connection bolts and its auxiliary connection can be fine
Consolidate the Lining Ring, cut not extra waste.
Circumferential weld connects bolt and its auxiliary connection 5 by a circumferential connection bolt, two circumferential nuts, two circumferential washer sets
At.
Longitudinal joint connects bolt and its auxiliary connection 4 includes a longitudinally connected bolt, two longitudinal nuts, two longitudinal washers
Composition.Every circumferential connection bolt, longitudinal nut are two-way, and both sides after two circumferential washers respectively by connecting two rings
Two longitudinal nuts are connected to nut, and by two longitudinal washers.
So far, although those skilled in the art will appreciate that the more of the utility model have been shown and described in detail herein
A exemplary embodiment still, still can be according to the utility model public affairs in the case where not departing from the spirit and scope of the utility model
The content opened directly determines or derives many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new
The range of type is understood that and regards as to cover other all these variations or modifications.
