There must be mishap, the normal operation of subway tunnel is related to the development process in whole city.
It is the construction quality of tunnel in itself to influence the principal element that subway tunnel uses.Shield machine appearance during such as shield construction
State controls improper or measurement error etc., causes tunnel axis unreasonable with gap of the shield tail, causes section of jurisdiction to crush situation, leaks
Regimen condition.When especially shield tunnel is constructed in the early stage, since the frictional force between section of jurisdiction and the soil body is smaller, and synchronous grouting is starched
Liquid sedimentation is not stablized also, and leans on system stiffness uneven after shield launching, and molded section of jurisdiction is integrally to active well in order to prevent
Displacement（The especially uneven dislocation in tunnel both sides）And cause tunnel axis offset, section of jurisdiction crushes, percolating water, screw rod are drawn
Break, it is necessary to molded section of jurisdiction is carried out overall fixed.The experience and Shen Tong groups constructed according to Shanghai Underground build tube hub
It is required that, it is desirable to provide this kind of set section of jurisdiction sockets device.
The content of the invention
Molded section of jurisdiction is overall in order to prevent causes tunnel axis offset, section of jurisdiction to crush, ooze to active well displacement
The problems such as leak, screw rod are pulled off, the present invention are to provide for a kind of construction at shield tunnel initial stage section of jurisdiction and socket device and construction
Method, when constructing in the early stage for solving shield tunnel, since the frictional force between section of jurisdiction and the soil body is smaller, and synchronous grouting is starched
Liquid sedimentation is not stablized also, and by the technical problem such as system stiffness is uneven after shield launching.
To achieve the above object, the technical scheme is that：
A kind of construction at shield tunnel initial stage section of jurisdiction sockets device, for preventing molded section of jurisdiction overall to active well position
Shift and cause tunnel axis offset, section of jurisdiction crushes, percolating water, screw rod are pulled off, the device include steel babinet, Manual hydraulic
Punching jack, anchor slab, fixed anchor, fining twisted steel, connector of finish rolling thread steel, section of jurisdiction center bolt, the steel babinet by
Front and rear portions babinet is formed, and front and rear portions babinet is fixedly connected by section of jurisdiction center bolt, and hand is housed in the front portion babinet
Hydraulic pressure punching jack, is respectively equipped with anchor slab in the front and rear portions babinet, the fining twisted steel passes through actuated hydraulic punching thousand
Jin top and section of jurisdiction center bolt center, and be fixedly connected with anchor slab.
Fining twisted steel length to required for constructing by connector of finish rolling thread steel spreading, and have with rear portion babinet
Effect connection.
A kind of construction method that device is socketed using shield tunnel construction at initial stage section of jurisdiction, Specific construction step：1）With pipe
Piece center bolt fixes front and rear portions babinet；2）Manual hydraulic punching jack is fixed on the curved plate in anterior babinet；
3）A piece fining twisted steel is passed through Manual hydraulic punching jack and section of jurisdiction center bolt center, and is fixed with anchor slab；4）
Remaining fining twisted steel spreading to construction is needed length with connector of finish rolling thread steel, and is effectively connected with rear portion babinet
Connect；5）Manually formula hydraulic pressure punching jack oil pressure, stretches fining twisted steel, needed before stretching to socket load into
Row is adjusted, and determines elongation；6）It is fixed with anchor slab, fixed anchoring after reaching construction requirement；7）Remove jack.
The beneficial effects of the invention are as follows：
It is used to not only conventional diameter that shield tunnel construction at the initial stage section of jurisdiction of the present invention, which sockets device and method,
6760mm balancing earth-pressure shielding machines, and suitable for the slurry balance shield machine of larger diameter, and after the completion of socketing, jack can
To remove, section of jurisdiction sockets problem when efficiently solving shield tunnel construction at initial stage.

Embodiment
With reference to specific embodiment, the present invention is further explained.
The present invention relates to a kind of construction at shield tunnel initial stage section of jurisdiction to socket device and construction method.Shield tunnel is first
When phase constructs, since the frictional force between section of jurisdiction and the soil body is smaller, and simultaneous grouting slurry sedimentation is not stablized also, and shield launching
It is uneven by system stiffness afterwards, in order to prevent molded section of jurisdiction it is overall to active well displacement and cause tunnel axis offset,
Section of jurisdiction crushes, percolating water, screw rod are pulled off, and spy invents this device.
As shown in Figures 1 to 9, shield tunnel construction at initial stage section of jurisdiction of the invention sockets device, including following sections：
Steel babinet 1, Manual hydraulic punching jack 2, anchor slab 3, fixed anchor, fining twisted steel 4, connector of finish rolling thread steel 5, section of jurisdiction
Center bolt 6.
Steel babinet 1 is made of front and rear portions babinet, and front and rear portions babinet is fixedly connected by section of jurisdiction center bolt 6, anterior case
Manual hydraulic punching jack 2 is housed in vivo, is respectively equipped with anchor slab 3 in front and rear portions babinet, fining twisted steel 4 passes through dynamic formula
6 center of hydraulic pressure punching jack 2 and section of jurisdiction center bolt, and be fixedly connected with anchor slab 3；Fining twisted steel 4 passes through finish rolling screw thread
5 spreading of steel connector length to required for constructing, and be effectively connected with rear portion babinet.
In constructing tunnel to 75 rings, i.e. section of jurisdiction abjection 25 ring of vehicle frame, start installation and socket device, in B1, B2 section of jurisdiction
Heart hole for hoist height and position is respectively installed a set of.Specific construction step：（1）Steel babinet 1 is fixed with section of jurisdiction center bolt（Front and rear two
Point）；（2）Jack is fixed in steel babinet 1（First half）On curved plate；（3）The finish rolling spiral shell of a root long 1m or so
