The shield tunnel lining structure can be provided with an unclosed secondary lining according to requirements such as function of the tunnel, distribution of the section, structural stress, structure waterproofing and the like, thereby preventing increment of diameter of the section of the tunnel caused by arranging the secondary lining in a total ring, reducing the manufacturing cost of the engineering, improving structural stress during the operation period, and enhancing waterproof effect of the tunnel.
Description
Technical field
The utility model relates to tunnel-like, is specifically related to a kind of shield tunnel lining structure that adopts non-sealing secondary lining.
Background technology
Shield tunnel is a kind of structure that adopts the segment assembly formation simultaneously of shield machine driving, and this structure is generally circle.Existing in the world at present shield tunnel construction has mono-layer tube sheet built and double-deck lining cutting, and wherein the secondary lining of double-deck lining cutting is in pipe-plate lining, to adopt cast-in-place mode to build totally-enclosed reinforced concrete structure.
Pipe-plate lining is in shield machine shield body, pipe sheet assembling to be become ring and release the shield body to form.Pipe-plate lining is made up of some sections of jurisdiction ring, and each section of jurisdiction ring is combined into (shown in the accompanying drawing 1 1) by some sections of jurisdiction.
The secondary lining of double-deck lining cutting is arranged on the inboard of pipe-plate lining, generally is to accomplish in the pipe-plate lining assembly unit, and to constructing under the glitch-free basically situation of shield machine construction.The secondary lining of the double-deck lining cutting of having adopted at present generally becomes closed circular setting (shown in the accompanying drawing 1 2) along shield tunnel circular cross section circumferencial direction.
There is following problem in actual use in the shield tunnel of above-mentioned double-deck lining cutting:
When 1, secondary lining was arranged circlewise, tunnel diameter needed to increase.Arrange that like the tunnel cross-section in the accompanying drawing 1 wherein tunnelling function usage space 3 need satisfy requirements such as construction, operation apart from the minimum distance L in tunnel shown in the control point 4.Secondary lining becomes to be periphery need not increase the tunnel cross-section diameter when more secondary lining not being set when putting.
2, the tunnel external diameter increases, and construction investment increases.Because the shield tunnel secondary liner structure often could be constructed than the tunnel segment structure hysteresis long period; Construction period still need rely on pipe-plate lining to bear external loads; Tunnel cross-section increases will make the pipe-plate lining structure stress more unfavorable; Might need to increase structural thickness and increase quantity of reinforcement, tunnel diameter increase meanwhile must cause the shield machine diameter bigger, and construction investment is more naturally.
3, the difficult control of construction quality.Secondary liner structure is generally accomplished the back cast-in-site in the pipe-plate lining assembly unit and is formed, and receives the construction technology restriction often can occur pouring into a mould uncompacted situation in the arch, tunnel, has influenced the stressed effect of double-deck liner structure integral body.
The utility model content
The purpose of the utility model is in order to solve the deficiency that the above-mentioned background technology exists; A kind of shield tunnel lining structure that adopts non-sealing secondary lining is proposed; Make it can avoid increasing tunnel cross-section, improve operation phase structure stress simultaneously, strengthen the tunnel water proofing effect because of loopful is provided with secondary lining.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of shield tunnel lining structure that adopts non-sealing secondary lining; Comprise pipe-plate lining and secondary lining, it is characterized in that said secondary lining is to mix clay structure what the pipe-plate lining inner surface was built along the nonocclusive reinforcing bar of shield tunnel circular cross section circumferencial direction.
Preferably, said secondary lining adopts cast-in-place mode to build.
Preferably, said secondary lining is arranged on shield tunnel section bottom or/and the sidepiece excess room is not provided with secondary lining for the part that receives tunnel function of use control.
In such scheme; At least one internal construction of said non-sealing secondary lining and tunnel internal can be connected to overall structure; Common bearing load; The connected mode of the internal construction of said in this case non-sealing secondary lining and tunnel internal can be the Integratively pouring type, also can be articulated manner.
In such scheme, the internal construction of said non-sealing secondary lining and tunnel internal also can not be connected to overall structure, and the internal construction of promptly non-sealing secondary lining and tunnel internal is independent structures separately.
In such scheme; Being connected between described non-sealing secondary lining and the pipe-plate lining can be adopted superimposed mode; Be non-sealing secondary lining with pipe-plate lining between directly contact between the corresponding contact surface, and shear reinforcement is set the reinforcing bar in reinforcing bar in the pipe-plate lining and the non-sealing secondary lining is linked together; Also can adopt complex method, be provided with between the corresponding contact surface between promptly non-sealing secondary lining and the pipe-plate lining and have the separation layer of water-proof function or do not establish separation layer.
The utility model is employed in the required spatial dimension of tunnelling function nonocclusive secondary lining mode is set outward, and its non-sealing secondary lining can require to be provided with according to tunnelling function, section layout, structure stress and structurally waterproof etc.On the one hand tunnel diameter is identical when any secondary lining is not set, and avoids causing that because of loopful is provided with secondary lining the tunnel cross-section diameter increases, and has reduced the construction cost of double-deck lining cutting shield tunnel significantly.On the other hand; Be provided with in the tunnel laterally, vertical internal construction (like carriageway plate and knee wall, flue sheet etc.) can be connected to integral body with non-sealing secondary lining, common bearing load has improved operation phase structural stress state; Improve the resistance to overturning of structure, strengthened the tunnel water proofing effect.
