Description
Technical field
This utility model relates to the concrete shield duct piece of a kind of pre-buried curved channel, mixed in shield method tunnel construction
The assembly of solidifying soil liner structure.
Background technology
Concrete shield duct piece is the structure component of shield method tunnel construction, and the permanent support being formed tunnel by assembly is tied
Structure.Existing shield duct piece refers to the Chinese patent of Application No. 201320410659.5.
In order to meet the needs of later stage operation, when after tunnel holing through, generally will be at assembled concrete shield duct piece
On perforate artificially, to install all kinds of support, set up all kinds of pipelines such as electromechanics, fire-fighting, draining, communication, to concrete shield pipe
The destruction of sheet is quite serious, and section of jurisdiction is prone to cracking, seepage, affects structural safety and service life, and later period maintenance operational difficulties,
Maintenance cost is high, even jeopardizes operation security.Additionally, artificial drilling efficiency is low, construction period is longer, and construction quality cannot
Ensureing, in work progress, the noise of generation, dust, vibrations etc. have a strong impact on workers ' health simultaneously, do not meet national green construction
Developing direction.
Utility model content
The purpose of this utility model is to provide a kind of installation safe ready, structural strength is higher, do not destroy shield duct piece, guarantor
Protect the concrete shield duct piece of the pre-buried curved channel of liner structure safety.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of pre-buried curved channel
Concrete shield duct piece, including shield duct piece body and be circumferentially embedded in the intrinsic curved channel of shield duct piece, shield
This internal steel reinforcement cage that is embedded with of structure section of jurisdiction, is provided with insulator spacer between curved channel and steel reinforcement cage.
By using technique scheme, the curved channel being embedded in concrete shield duct piece does not connects with steel reinforcement cage
Touching or be dielectrically separated from contact point, can avoid the generation of stray electrical current, the structure of arc can be divided to a certain extent simultaneously
Dissipate active force, it is ensured that installation safe ready, structural strength are higher.After this shield duct piece completes assembly, can be in tunnel-liner
Cambered surface forms the equally spaced curved channel being distributed ringwise, and all kinds of supports, support etc. are tied with tunnel-liner by curved channel
Structure is connected, and has reached not destroy shield duct piece, the purpose of protection liner structure safety, and easy for installation, construction environment is good, work
Efficiency is high, can effective reduction of erection time, and avoid concrete shield duct piece perforate, it is ensured that the safety of xoncrete structure.
It is also preferred that the left insulator spacer is external series gap.
By using technique scheme, insulating effect can be played to a certain extent, the most effectively avoid stray electrical
The generation of stream.
It is also preferred that the left insulator spacer is insulation spacer, insulation spacer is made up of insulant.
By using technique scheme, insulating effect can be played to a certain extent, the most effectively avoid stray electrical
The generation of stream, is simultaneously connected with relatively stable, and structural strength is higher.
It is also preferred that the left be provided with cambered surface grout hole and hand hole on shield duct piece body, curved channel be positioned at cambered surface grout hole and
Between hand hole.
By using technique scheme, structure arranges relatively reasonable so that structure is the most stable.
It is also preferred that the left be provided with dowel radially between shield duct piece body and curved channel.
By using technique scheme, play certain stiffening effect, the requirement for bearing capacity that pipeline is installed can be met.
It is also preferred that the left curved channel is positioned at the compass of steel reinforcement cage.
By using technique scheme, it is to avoid destroy structure too much, it is ensured that overall structural strength.
In sum, this utility model has the advantages that the curved channel being embedded in concrete shield duct piece
Do not come in contact with steel reinforcement cage or be dielectrically separated from contact point, the generation of stray electrical current, the simultaneously structure of arc can be avoided
Can dissipation of ferees to a certain extent, it is ensured that safe ready, structural strength are installed higher.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.The most identical parts are with identical accompanying drawing
Labelling represents.It should be noted that the word "front", "rear" used in describing below, "left", "right", "up" and "down" refer to
Being the direction in accompanying drawing, word " bottom surface " and " end face ", " interior " and " outward " refer respectively to towards or away from particular elements geometry
The direction at center.
Embodiment 1: the concrete shield duct piece of a kind of pre-buried curved channel 2, including shield duct piece body 1, shield duct piece
Being embedded with curved channel 2 in body 1, curved channel 2 is distributed ringwise.
The interior of shield duct piece body 1 is also embedded with steel reinforcement cage simultaneously, and steel reinforcement cage plays stiffening effect, curved channel 2
And it is provided with insulator spacer between steel reinforcement cage.
Insulator spacer is actual can be external series gap, i.e. curved channel 2 and steel reinforcement cage does not comes in contact.
Being provided with cambered surface grout hole 4 and hand hole 3 on shield duct piece body 1, curved channel 2 is positioned at cambered surface grout hole 4 and hands
Between hole 3, it is provided with grouting 6 when grouting at cambered surface grout hole 4.Curved channel 2 is positioned at the compass of steel reinforcement cage.
Embodiment 2: as it is shown on figure 3, insulator spacer is insulation spacer 7, insulation spacer 7 is made up of insulant, permissible
It it is elastomeric material.It is provided with dowel 5 radially between shield duct piece body 1 and curved channel 2 simultaneously.
First curved channel 2 is fastened between die bottom plate grout hole and hand hole 3, then shield duct piece steel reinforcement cage is put into mould
In tool, adjust steel reinforcement cage and the position of curved channel 2 and cover to reinforcement distance, in the portion that steel reinforcement cage contacts with curved channel 2
