Abstract
The utility model relates to tunnel, in particular to an uneven connecting structure between a lining pipe sheet and an inner lining used in shield method tunnel. The utility model is provided with a tenon groove which is arranged on junction between the lining pipe sheet and the inner lining with the aim to make the lining pipe sheet and the inner lining be effectively connected; the connecting face can transmit pressure, shearing force and flexural torque so as to be stressed together as a superposition component and reduce structural thickness. The utility model has the advantages of increasing the shearing resistant capability of the connecting face of the lining pipe sheet and the inner lining, guaranteeing the inner and outer linings work as an integrated superposition component so as to reduce structural thickness and provide considerable economic benefit.
Description
Technical field
The utility model relates to tunnel-like, relates to a kind of concave-convex connection structure 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 purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of concave-convex connection structure that is used between shield tunnel lining segment and inner lining is provided, this structure is by being provided with tongue-and-groove on 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 utility model purpose realizes being finished by following technical scheme:
A kind of concave-convex connection structure that is used between shield tunnel lining segment and inner lining, comprise lining segment and the inner lining that is positioned at the lining segment inboard, described inner lining is connected with the lining segment intrados by monobloc cast, it is characterized in that the intrados of lining segment is provided with the tongue-and-groove of concave-convex surface.
The distribution of the tongue-and-groove of described concave-convex surface along the intrados of lining segment continuously, successively, evenly distribute also can be interrupted being provided with along the intrados of lining segment.
The projection or the recessed height of the tongue-and-groove of described concave-convex surface are not less than 6mm.
The utility model has the advantages that, can increase the shear resistance on outer lining cutting and inner lining mating face, guarantee ectonexine lining cutting superposed member work as a whole to a certain extent, 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 the utility model syndeton schematic diagram;
Accompanying drawing 4 is the local structure for amplifying schematic diagram of the utility model tongue-and-groove;
Concrete technical scheme
The utility model feature 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:
Shown in Fig. 1-4, label 1-6 represents respectively: outer lining segment 1, inner lining 2, waterproof layer 3, tenon groove structure 4, groove 5, tenon 6.
Embodiment: present embodiment is made of outer lining segment 1 and the inner lining 2 that is positioned at the lining segment inboard, the intrados of lining segment 1 is provided with the tenon groove structure 4 of the concave-convex surface that is made of continuously successively groove 5, tenon 6, tenon 6 and groove 5 run through the intrados of section of jurisdiction 1, and the intrados of inner lining 2 by monobloc cast and lining segment 1 is connected and fixed and is one.
The recessed depth bounds of tenon 6 heights of projection or groove 5 is being not less than 6mm, and the shearing resistance effect of tongue-and-groove is that the aggregate interlock effect by bonding surface guarantees.Its size and spacing should be consistent with aggregate size, mainly are to form the nature matsurface.Its value can be with reference to the requirement of superposed type member.
Present embodiment when implementing, treat that normally outer lining segment 1 assembly unit is finished after, that carries out inner lining 2 again wholely waters construction.
Claims (4)
