Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figures 1 to 4, a kind of shield duct piece of preferred embodiment of the present utility model, it includes multiple by coagulation
The Lining Ring 1 of native pouring molding, the Lining Ring 1 include bind block 11, several adjacent blocks 12 and several calibrated bolcks 13,
Be fixedly connected sequentially between the block 11 that binds, adjacent block 12 and calibrated bolck 13 and formed one closing Lining Ring 1, the lining
A diameter of 5200mm of ring 1 is built to 6500mm any values, wall thickness is 350mm to any value between 400mm, and each lining
Multiple longitudinal bolts 2 are passed sequentially through before and after between block ring 1 to be uniformly fixedly connected and form the shield duct piece.
Thus, shield duct piece of the present utility model is mainly the block 11 that binds, the adjacent block 12 formed by concreting
An a diameter of 5200mm is spliced into 6500mm any values with calibrated bolck 13, and wall thickness is 350mm to any value between 400mm
Lining Ring 1, and difference binds between block 11, adjacent block 12 and calibrated bolck 13, and the company of being fixed to one another between each Lining Ring 1
A stiffness by itself that can improve tunnel is connected into, can effectively prevent tunnel from the shield duct piece of situations such as ellipse change, crack occur,
For there is the tunnel of deeper soft foundation, and construct correction or curve simulation can be carried out.
Further, the Lining Ring 1 is standard Lining Ring, left-hand bend Lining Ring or right-hand bend Lining Ring.Due to wedge shape
Amount is the Breadth Maximum of cambridge ring and the difference of minimum widith, and limit cornering ability is 300mm, to meet curve simulation and construction
The needs of correction, under normal circumstances shield duct piece be sequentially connected using standard Lining Ring, when find shield duct piece there is deflection, just
It can be adjusted with left-hand bend Lining Ring or right-hand bend Lining Ring, therefore by the left-hand bend Lining Ring and right-hand bend lining cutting
The wedge shape amount of ring is both preferably 37.2mm；The block 11 that binds is arranged to one piece, and the adjacent block 12 is arranged to two pieces, the mark
Quasi- block 13 is arranged to three pieces.Three calibrated bolcks 13 are in turn connected to form the semicircular bottom of the shield duct piece, two institutes
State the both ends that adjacent block 12 is separately fixed at the semicircular bottom, the block 11 that binds be fixed on two adjacent blocks it
Between, and pass sequentially through ring bolt 3 and be fixed connection.The calibrated bolck 13, adjacent block 12 and bind block 11 it is each mutually it
Between be fixedly connected using 10 ring bolts 3, ring bolt 3 is preferably M30 bolts herein, lining described in front and rear each two
It is fixedly connected, is embodied as using 16 longitudinal bolts 2 between block ring 1：Bind between block 11 and adjacent block 12 with
And the M30 bolt connections of shared 10 rings are fixed between adjacent block 12 and calibrated bolck 13 and between calibrated bolck 13, in lining cutting
It is fixedly connected between ring 1 with 16 longitudinal bolts 2, longitudinal bolt 2 is respectively distributed 3 in the end of calibrated bolck 13 and adjacent block 12,
Bind and 1 longitudinal bolt 2 is set on block 11, the angle between adjacent longitudinal bolt 2 is A, and A is preferably 22.5 °, when the block that binds
11st, after adjacent block 12 and calibrated bolck 13 splice cyclization, the distance of the hand hole of longitudinal bolt 2 diametrically is equal.
Further, by the preferably wedge of block 11 that binds, the ring bolt 3 preferably curved bolt, Ge Gesuo
It is preferably straight bolt to state the longitudinal bolt 2 connected between Lining Ring；The internal diameter of the Lining Ring 1 is preferably 5440mm, the lining
The thickness for building ring 1 is preferably 380mm, and the width of the Lining Ring 1 is preferably 1200mm, and thus, the Lining Ring 1 can either improve
The stiffness by itself in tunnel, it can effectively prevent tunnel from the shield duct piece of situations such as ellipse change, crack occur, it is deeper soft for having
The tunnel of weak ground, and construct correction or curve simulation can be carried out.
In summary, shield duct piece of the present utility model is mainly the block 11 that binds, the adjoining formed by concreting
Block 12 and calibrated bolck 13 are spliced into an a diameter of 5200mm to 6500mm any values, and wall thickness is that 350mm appoints between 400mm
The Lining Ring 1 of one value, and difference binds between block 11, adjacent block 12 and calibrated bolck 13, and consolidate each other between each Lining Ring 1
Surely a stiffness by itself that can improve tunnel is connected into, can effectively prevent tunnel from the shield of situations such as ellipse change, crack occur
Section of jurisdiction, for there is the tunnel of deeper soft foundation, and construct correction or curve simulation can be carried out.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvement and deformation can also be made, these improve and become
