Description
Technical field
The invention belongs to Tunnel Engineering technical field, rigidity when being related to a kind of shield tunnel lining structure staggered joint erection adds
Intensity device.
Background technology
Shield tunnel is once damaged as the urban track traffic underground structure of major motor vehicle engineering in a certain part,
Corresponding influence can all be produced to the overall structure life-span according to different damaged conditions.Shield tunnel lining structure is spelled by section of jurisdiction
Connecing to be formed, the seam after pipe sheet assembling is divided into longitudinal seam and ring seam, and edge joint position is the weak link of liner structure stress,
So pipe sheet assembling can closely strengthen the strength and stiffness of liner structure to a certain extent.The adjacent tunnel segment structure of shield tunnel is whole
Body relies primarily on track bolt to maintain, and all linear deformation can occurs due to a variety of causes in construction stage and operation stage,
Such as different geological conditions, different buried depth, WATER LEVEL CHANGES, different forms of construction work, Different Ground load and different peripheries
The various factors such as environmental change.Supporting construction of the section of jurisdiction as shield tunnel after assembly, once there is the underground of erosion carbon dioxide
Water seepage, track bolt corrode and then section of jurisdiction is produced crack or make tunnel that longitudinal differential settlement etc. occur.With splitting
The gradual development section of jurisdiction splicing seams joint open of seam is excessive and leak occurs, and section of jurisdiction concrete erosion causes section of jurisdiction self-strength to subtract
Small, track bolt corrosion causes joint impermeability decrease etc., and then influences the usability and security of shield tunnel.
Shield tunnel largely all starts to use staggered joint erection liner structure at present, using the shield tunnel of staggered joint erection section of jurisdiction
Road provides extensively development platform in the superiority of deformation, waterproof control aspect.The feelings that adjacent two interannulars longitudinal joint mutually staggers
Condition is referred to as staggered joint erection, and the erection method of staggered joint erection can be uniformly distributed annulus seam rigidity, to reduce the deformation of structure.
Compared with staggered joint erection is vertical, circumferential weld intersection is in the T-shaped cross with through seam assembling is vertical, circumferential weld is intersecting, the plane of weakness of seam
Reduce, deformation it is smaller be advantageous to preventing water leakage, if while occur leak phenomenon it is also more disposable.Shield tunnel lining structure seam
Place's rigidity relies primarily on track bolt to maintain, and being concentrated mainly on different loads for lining cutting pipe ring seam crossing rigidity both at home and abroad makees
With, different high-strength bolt pretensions, different bolt radicals, varying strength bolt, different joint forms etc. studied,
And for actively increasing the mode of internal force and then enhancing between adjacent section of jurisdiction after the completion of pipe sheet assembling simultaneously under staggered joint erection mode
Liner structure rigidity, the deformation this respect research of reduction liner structure are less.
The content of the invention
It is an object of the invention to provide a kind of rigidity and its globality for strengthening liner structure, ensures that tunnel-liner does not invade
The shield tunnel staggered joint erection liner structure rigidity stiffening device of tunnel structure building line, technical scheme are as follows：
A kind of shield tunnel staggered joint erection liner structure rigidity stiffening device, the shield tunnel fissure of displacement strengthened for active are spelled
The rigidity pretended between adjacent pipe ring, including it is bolted and is welded to connect the steelframe 2 being fixed on section of jurisdiction 1, fixture 6 and two
Kind reinforcing pull bar, wherein,
Connected between the steelframe of adjacent tubes interannular by reinforcing pull bar, it is equal in the point midway of every steelframe and both ends
Bolt hole is offered, being divided into fastening end according to the position difference for being overlapped on steelframe reinforces pull bar 3 and fixing end reinforcing pull bar 4, tightly
Fixed end reinforces the corresponding both ends that pull bar 3 is overlapped on longitudinally adjacent steelframe, and fastening end reinforces the spiral shell that pull bar passes through adjacent steelframe
Keyhole is simultaneously tightened fixation with nut；Fixing end reinforces the both ends of pull bar 4, and one end is fastening end 13, and the other end is fixing end
14, fixing end 14 is provided with rhombus head and anti-rotation tenon, is connected with steelframe point midway 11 by fixture 6, fastening end 13 is worn
Cross the bolt hole of the respective end of longitudinally adjacent section of jurisdiction steelframe and tightened fixation with nut；
Described fixture 6 includes rotation end stand 8 and the standing screw 9 being connected with each other with circular shear connector, rotates end stand 8
It can be rotated freely around the axle of standing screw 9, rotation end stand 8 is provided with reinforces in the fixing end 14 of pull bar 4 to interspersed fixing end
Between hole, the anti-rotation tongue-and-groove for preventing fixing end from reinforcing pull bar rotation is provided with interstitial hole, fixing end reinforced pull bar by standing screw 9
Fixing end be fixed on rotation end stand at.
The present invention has advantages below：
1. the present apparatus can actively increase the reinforcing of shield tunnel fissure of displacement splicing tubes interannular internal force, effectively reduce due to various factors
The changing of the relative positions between caused pipe ring so that annulus seam Stiffness Distribution is uniform, reduces the deformation of structure, be shield tunnel in severe class
The globality of type area construction reinforced pipe ring structure provides method and measure；
2. staggered joint erection is vertical, circumferential weld intersection compared with the cross under through seam assembling is vertical, circumferential weld is intersecting, connects in T-shaped
The plane of weakness of seam, which is reduced, deformation is smaller is advantageous to preventing water leakage, if while occur leak phenomenon it is also more disposable.
3. in the present apparatus, number of parts is few, compact-sized, it can relatively easily reach sufficiently large loading tensile, be
Shield tunnel construction process and later stage use add safety guarantee；
4. the present apparatus is in terms of construction, install convenient is simple to operate, convenient disassembly；
5. unloading can realize stepless unloading initial stage, avoid and destroyed because of Condition of Sudden Unloading caused by liner structure；
6. because the research both at home and abroad for internal force active loading problem between adjacent section of jurisdiction is less, the present invention can be later should
The research in field provides reference.
