Description
Technical field
The utility model belongs to Shield Construction Technique field, and in particular to the anti-faulting of slab ends mounting structure of shield duct piece.
Background technique
Shield duct piece is the main mounting structure of shield-tunneling construction, is the innermost layer barrier in tunnel, carries and resists soil layer pressure
The effect of power, groundwater pressure and some special loads.Shield duct piece is the permanent lining, secondary lining structure of shield tunnel, shield pipe
Tablet quality is directly related to the total quality and safety in tunnel, influences the waterproof performance and endurance quality in tunnel.
With the continuous development of social progress and city, subway is gradually improved, and more and more subway works rely on shield
Method is completed, although shield duct piece mounting technique is mature, but still there are some more scabrous drawbacks, for example are mutually linked
Shield duct piece between inevitably there is faulting of slab ends phenomenon, after the faulting of slab ends of Shield tunnel refers to shield segment assembling here, phase
Adjacent section of jurisdiction inner wall is not the cambered surface, the mutual changing of the relative positions the phenomenon that, in shield method tunnel construction and acceptance specification GB 50446-2017
After having corresponding tolerance value, faulting of slab ends to occur, later period adjustment section of jurisdiction relative position is not easy, and influences shield-tunneling construction quality.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of anti-faulting of slab ends mounting structure of shield duct piece, avoids shield
There is faulting of slab ends phenomenon in structure section of jurisdiction.
In order to solve the above technical problems, the utility model adopts the following technical solution: the anti-faulting of slab ends mounting structure of shield duct piece,
Along tunnel, circumferentially splicing cyclization, the two shield duct piece circumferential direction fissure of displacement adjacent along length of tunnel direction are arranged and adopt several shield duct pieces
It is bolted with connection, anti-faulting of slab ends pressure plate fastener, the mistake proofing is equipped between two shield duct pieces adjacent along length of tunnel direction
Platform pressure plate fastener includes two pieces of anti-faulting of slab ends pressing plates, and the anti-faulting of slab ends pressing plate is steel plate, the anti-faulting of slab ends pressing plate include fixed part with
And the interconnecting piece set on fixed part opposite end, the fixed part of two pieces of anti-faulting of slab ends pressing plates, which overlaps, to be fixed, and the shield duct piece is equipped with spiral shell
Bolt fixing groove, the interconnecting piece are fixed in bolt fixing groove using fixing bolt.
The technical solution adopted in the utility model is equipped with anti-faulting of slab ends between two shield duct pieces adjacent along length of tunnel direction
Pressure plate fastener, can prevent section of jurisdiction shield tunnel arc to sliding and radial location free procedure in section of jurisdiction it is circumferential with radial mistake
Platform.
Preferably, the fixed part of two pieces of anti-faulting of slab ends pressing plates is welded and fixed.
Preferably, the bolt fixing groove is equipped with constant inclined surface, and the interconnecting piece fitting constant inclined surface is fixed.
Preferably, the width of the fixed part is greater than the width of interconnecting piece, is isosceles between the fixed part and interconnecting piece
Trapezium structure.
Preferably, the anti-faulting of slab ends pressing plate is Q235 steel plate.
The specific technical solution and its advantages of the utility model will combine attached in the following detailed description
Figure is described in detail.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and detailed description:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of anti-faulting of slab ends pressing plate in the utility model.
Specific embodiment
Referring to fig. 1 and fig. 2, the anti-faulting of slab ends mounting structure of shield duct piece, several shield duct pieces 2 are circumferentially spliced into along tunnel
Ring is bolted along the adjacent two shield duct piece circumferential direction fissure of displacement setting in length of tunnel direction and using connection, along length of tunnel side
To between two adjacent shield duct pieces be equipped with anti-faulting of slab ends pressure plate fastener 1.Although two shield duct pieces adjacent along length of tunnel direction
Connection has been used to be bolted, but the screw hole of section of jurisdiction has the gap with bolt, occurs in floating-upward process there are also section of jurisdiction
Faulting of slab ends, bolt do not play operation, therefore, anti-faulting of slab ends pressure plate fastener, can prevent section of jurisdiction shield tunnel arc to sliding and
Section of jurisdiction circumferential direction and radial faulting of slab ends in radial location free procedure.
Wherein, the anti-faulting of slab ends pressure plate fastener includes two pieces of anti-faulting of slab ends pressing plates, and the anti-faulting of slab ends pressing plate is steel plate, described anti-
Faulting of slab ends pressing plate includes fixed part 11 and the interconnecting piece 12 set on fixed part opposite end, the fixed part overlapping of two pieces of anti-faulting of slab ends pressing plates
Fixed, the shield duct piece is equipped with bolt fixing groove, and the interconnecting piece is fixed in bolt fixing groove using fixing bolt, connects
Portion is equipped with the through-hole 121 passed through for fixing bolt.It can use the existing bolt fixing groove of shield duct piece, anti-faulting of slab ends pressure is stated in increase
Board fastener realizes anti-faulting of slab ends effect.
Preferably, the fixed part of two pieces of anti-faulting of slab ends pressing plates is welded and fixed, and facilitates installation, and fixation.The bolt is solid
Slot is determined equipped with constant inclined surface, and the interconnecting piece fitting constant inclined surface is fixed, and tightens fixing bolt to facilitate.The width of the fixed part
Degree is greater than the width of interconnecting piece, is isosceles trapezoidal structure between the fixed part and interconnecting piece, and fixed part has biggish fixation
Area, and interconnecting piece lesser width facilitates access for bolt fixing groove, can reduce stress by isosceles trapezoidal structure transition.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, being familiar with the those skilled in the art should be understood that the utility model includes but is not limited to retouch in specific embodiment above
