Abstract
A shield tunnel lining ring is characterized by comprising six mutually matched and connected Z-shaped pipe pieces (1), an adjacent pipe piece (2) and a top sealing pipe piece (3). A protrusion protruding out of an end face is placed at each end of each Z-shaped pipe piece (1), one protrusion protrudes outwards along an outer arc face, and another protrusion protrudes outwards along an inner arc face. A protrusion protruding along the outer arc face is placed at each end of the adjacent pipe piece (2), and a protrusion protruding along the inner arc face is placed at each end of the top sealing pipe piece (3). All protrusions are matched with corresponding end faces to form connection steps, each protrusion is matched with corresponding step face to enable the Z-shaped pipe pieces (1), the adjacent pipe piece (2) and the top sealing pipe piece (3) to be connected to form an integral round ring structure. The shield tunnel lining ring is strong in integral rigidity, good in positioning property, easy to assemble and capable of being rotated 0-180 degrees to achieve a purpose of assembling in staggered joints. Pipe pieces of a tunnel with a long straight section are enabled to be assembled, construction quality is improved, and construction difficulty is reduced.

Background technology
As everyone knows, shield tunnel adopts the shield duct piece lining cutting as the liner structure of permanent support, and its quality directly affects the normal use in tunnel.Therefore the tunnel segment structure design is one of important step of shield tunnel project quality control.To consider weight, the assembly unit convenience of every section of jurisdiction for the design of duct pieces of shield tunnel, and the mechanical characteristics of whole Lining Ring, integrated connection rigidity etc.Therefore for shield tunnel, the integral rigidity that reasonably connects section of jurisdiction connected mode energy reinforced pipe sheet built, reasonably section of jurisdiction piecemeal quantity and the section of jurisdiction angle that binds can effectively reduce the assembly unit difficulty, reasonably the erection method of longitudinal bolt number and staggered joint erection and fissure of displacement lap length etc. can effectively improve longitudinal rigidity, thereby improve the shock resistance in tunnel, increase the ability of opposing differential settlement etc.And according to the knowledge of the applicant, present shield tunnel liner ring all reckons without above-mentioned factor, causes shield duct piece to exist integral rigidity discontinuous, and inconvenience is installed, the shortcoming that barrier performance is weak.
Summary of the invention
The purpose of this utility model is simple for existing shield tunnel liner chip architecture, and inconvenience is installed, and the problem that intensity is not high designs a kind of assembly unit, shield tunnel liner ring that integral rigidity is strong be convenient to.
The technical solution of the utility model is:
A kind of shield tunnel liner ring, it is characterized in that it is by six Z-type sections of jurisdiction 1 that cooperatively interact continuous, a slice in abutting connection with the section of jurisdiction 2 and a slice section of jurisdiction 3 of binding combine, respectively there is a projection of protruding end face at the two ends of described Z-type section of jurisdiction 1, one of them projection is outwards protruding along extrados, another projection is along intrados place outer lug, described in abutting connection with the section of jurisdiction 2 two ends respectively be provided with one along the outside projection of extrados, and 3 two ends, section of jurisdiction of binding respectively are provided with one along the outside projection of intrados, described each projection all with connection step of corresponding end face formation, thereby each protruding all matching with corresponding step surface makes Z-type section of jurisdiction 1, in abutting connection with the section of jurisdiction 2 and the section of jurisdiction 3 of binding connect into the circular ring structure of an integral body.
Described every Z-type section of jurisdiction 1 and in abutting connection with the section of jurisdiction central angle of 2 correspondences is 52 °, the central angle of section of jurisdiction 3 correspondences that bind is 28 °, central angle corresponding to each projection is 2 °.
The described high spot that matches is equipped with track bolt 4.
Described Z-type section of jurisdiction 1, on section of jurisdiction 2 and the section of jurisdiction 3 of binding, radially breechblock 5 is installed.
The quantity of described radially breechblock 5 is 30, and they are arranged along the Central Symmetry of the section of jurisdiction 3 of binding.
The beneficial effects of the utility model:
Duct pieces of shield tunnel of the present utility model is easy to assembly unit, integral rigidity is strong, has especially adopted the duct piece connector mode of Z-type, has strengthened the integrality of shield tunnel construction, improves the rigidity of tunnel structure; In addition, the Z-type joint is beneficial to the pipe sheet assembling in straightway tunnel, improves construction quality, reduces difficulty of construction.The tunnel lining ring that adopts this " 6+1+1 " section of jurisdiction to consist of also adopts basic staggered joint erection mode, can select 0 ° ~ 180 ° the interannular anglec of rotation, guarantees the effect of the fissure of displacement.
The utility model has solved the rigidity discontinuous problem between section of jurisdiction and the section of jurisdiction, has strengthened simultaneously the integrality of shield tunnel construction, improves the rigidity of tunnel structure;
The utility model adopts the Z-type joint to be conducive to the pipe sheet assembling in tunnel, is convenient to the location, section of jurisdiction, improves construction quality, reduces difficulty of construction;
The utility model adopts the Z-type joint to be conducive to increase the waterpower osmosis path, can prevent treatment technology for tunnel seepage.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that forms three kinds of sections of jurisdiction of the utility model Lining Ring.
Fig. 3 is the distribution schematic diagram of connecting bolt in the Lining Ring of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As Figure 1-3.
A kind of shield tunnel liner ring, it is by six Z-type sections of jurisdiction 1 that cooperatively interact continuous, a slice in abutting connection with the section of jurisdiction 2 and a slice section of jurisdiction 3 of binding combine, as shown in Figure 1, respectively there is a projection of protruding end face at the two ends of described Z-type section of jurisdiction 1, one of them projection is outwards protruding along extrados, another projection is along intrados place outer lug, described in abutting connection with the section of jurisdiction 2 two ends respectively be provided with one along the outside projection of extrados, and 3 two ends, section of jurisdiction of binding respectively are provided with one along the outside projection of intrados, as shown in Figure 2, described each projection all with connection step of corresponding end face formation, thereby each protruding all matching with corresponding step surface makes Z-type section of jurisdiction 1, in abutting connection with the section of jurisdiction 2 and the section of jurisdiction 3 of binding connect into the circular ring structure of an integral body.Described every Z-type section of jurisdiction 1 and in abutting connection with the section of jurisdiction central angle of 2 correspondences is 52 °, the central angle of section of jurisdiction 3 correspondences that bind is 28 °, central angle corresponding to each projection is 2 °, i.e. (52 ° * 7+28-2 ° * 2 * 8)=360 °.The described high spot that matches is realized linking to each other by track bolt 4.Described Z-type section of jurisdiction 1, on section of jurisdiction 2 and the section of jurisdiction 3 of binding, radially breechblock 5 is installed.The quantity of described radially breechblock 5 is 30, and they are arranged along the Central Symmetry of the section of jurisdiction 3 of binding.As shown in Figure 3.
