Abstract
The invention relates to a connecting structure between liner tube and inner liner in shield tunnel, wherein the combine face between the liner tube and the inner liner is disposed with an anchor bar is disposed to combine them effectively, the combine face can transmit pressure, shear force and torque, to force the layered elements together and reduce structural thickness. The invention can improve the shear and drawing resistances on the combine face, to integral the inner and outer liners, while the invention can reduce structural thickness and improve benefits.
Description
Technical field
The present invention relates to tunnel-like, relate to a kind of method of attachment that is used between shield tunnel lining segment and inner lining concretely.
Background technology
Shield tunnel is used widely in big depth underground engineering, along with engineerings such as city large-sized launching pipeline, pressurized water transmission tunnel are used shield method, the force status of liner structure becomes increasingly complex, and should bear outside water and soil pressure, also will bear internal water pressure.The individual layer prefbricated tunnel lining can not satisfy the structure stress requirement, and necessary cast-in-place secondary monolithic lining is jointly as bearing structure.In bearing the shield tunnel engineering of internal pressure,, generally need to adopt double-deck liner structure for satisfying the needs of technological requirement, correction construction error and structure stress.Outer lining and interliner face adopt following construction measure usually: grooves such as the preceding bolt hand hole with outer lining cutting section of jurisdiction inner surface of lining processing, injected hole, lifting eye are floating with cement placement, re-lay one deck waterproof film, only transmit pressure between the ectonexine and do not have shearing and moment of flexure; Inner lining concrete even reinforcing bar stretch in the groove such as outer section of jurisdiction hand hole, and these positions can localized delivery pressure, shearing and moment of flexure; Build the preceding bigger groove of floating outer tube plate inner surface of liner, all the other positions are cut a hole hair or are not dealt with.In the above-mentioned situation owing between inside and outside layer, can only transmit pressure and part shearing, therefore need the lining segment and the liner of big thickness, the construction material volumetric usage that thickness is big is big, along with the increase of length of tunnel, will directly cause the obvious increase of engineering cost.And in common engineering,, all wish to get less section of jurisdiction and thickness of inner lining usually owing to be subjected to the engineering specifications restriction.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of method of attachment that is used between shield tunnel lining segment and inner lining is provided, this method is by being provided with dowel between the mating face between lining segment and inner lining, the two is fused effectively, pressure, shearing and moment of flexure can be transmitted in its mating face, it is stressed jointly to press superposed member, to reduce its structural thickness.
The object of the invention realizes being finished by following technical scheme:
A kind of method of attachment that is used between shield tunnel lining segment and inner lining, it is characterized in that described method adopts following steps: at first be prefabricated lining segment, inner cambered surface one side is buried dowel in advance underground in the reinforcing cage of lining segment; Next carries out the assembly unit of outer lining cutting section of jurisdiction; After treating that afterwards outer lining segment assembly unit is finished, dig out pre-buried dowel, clod wash is to design attitude; That carries out inner lining at last wholely waters construction, and the end that dowel is dug out is embedded in the inner lining.
But described dowel is the dowel of clod wash.
Being provided with along the intrados of lining segment of described dowel evenly distributes.
The horizontal and vertical interval of described dowel must not be greater than 500mm.
Advantage of the present invention is, can increase the tension and the shear resistance on outer lining cutting and inner lining mating face, prevents the disengagement of ectonexine lining cutting, guarantees ectonexine lining cutting superposed member work as a whole.Both can reduce structural thickness, have more considerable economic.
Description of drawings
Accompanying drawing 1 is directly to contact the syndeton schematic diagram in the prior art;
Accompanying drawing 2 is the water layer syndeton schematic diagram of setting up defences in the prior art;
Accompanying drawing 3 is syndeton schematic diagram of the present invention;
Concrete technical scheme
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-3, label 1-5 represents respectively: an end 5 of outer lining segment 1, waterproof layer 2, inner lining 3, dowel 4, dowel 4.
Embodiment: the step that a kind of method of attachment that is used between shield tunnel lining segment and inner lining that present embodiment relates to is adopted is: at first be prefabricated lining segment 1, inner cambered surface one side in the reinforcing cage of lining segment 1, but bury the dowel 4 of clod wash in advance underground; Next carries out the assembly unit of lining segment 1; After treating that afterwards outer lining segment 1 assembly unit is finished, dig out an end 5 of pre-buried dowel 4, clod wash in case of necessity, can be cut a hole hair to outer lining segment 1 intrados simultaneously and handle to design attitude; That carries out inner lining 3 at last wholely waters construction, and the end 5 that dowel 4 is dug out is embedded in the inner lining 3.The intrados of inner lining 3 by monobloc cast and lining segment 1 is connected and fixed and is one.
Being provided with along the intrados of lining segment 1 of dowel 4 evenly distributes.
The present embodiment joint construction requires to propose with reference to the structure of superposed type member.The horizontal and vertical spacing of dowel 4 should be definite according to calculating, generally should not be greater than 500mm.The buried depth of dowel 4 in outer lining segment 1 and inner lining 3 should be less than the diameter of 10 times of dowels 4.
Claims (3)
1. method of attachment that is used between shield tunnel lining segment and inner lining, it is characterized in that described method adopts following steps: at first be prefabricated lining segment, inner cambered surface one side in the reinforcing cage of lining segment, bury dowel in advance underground, being provided with along the intrados of lining segment of described dowel evenly distributes; Next carries out the assembly unit of outer lining cutting section of jurisdiction; After treating that afterwards outer lining segment assembly unit is finished, dig out pre-buried dowel, clod wash is to design attitude; That carries out inner lining at last wholely waters construction, and the end that dowel is dug out is embedded in the inner lining.
2. a kind of method of attachment that is used between shield tunnel lining segment and inner lining according to claim 1, but it is characterized in that the dowel of described dowel for clod wash.
3. a kind of method of attachment that is used between shield tunnel lining segment and inner lining according to claim 1 and 2 is characterized in that the horizontal and vertical interval of described dowel must not be greater than 500mm.
