Abstract
A shield method tunnel circular prefabricated reinforced concrete lining structure can satisfy the demands of structure stress and a shield method, and meanwhile can satisfy the demands of human body comfort of passengers when a train travels in a maximum traveling speed of 120 km/h. A tunnel lining is formed by connecting of single layer circular-ring-shaped prefabricated reinforced concrete earth shield rings along the extending direction of a line. The single layer circular-ring-shaped prefabricated reinforced concrete earth shield rings are formed by prefabricated unit bodies in an assembling mode along a ring direction. The inner diameters of the single layer circular-ring-shaped prefabricated reinforced concrete earth shield rings are 6.00 m, and the outer diameters of the single layer circular-ring-shaped prefabricated reinforced concrete earth shield rings are 6.70 m, and the widths of the single layer circular-ring-shaped prefabricated reinforced concrete earth shield rings are 1.50 m.

Technical field
The utility model relates to construction of tunnel, particularly the circular prefabricated reinforced concrete liner structure of the urban rapid railway traffic running tunnel of a kind of highest running speed 120km/h that adopts shield-tunneling construction.
Background technology
At present the domestic city rail rapid transit running tunnel overwhelming majority adopts shield constructions, and the interior diameter of shield method running tunnel is 5.40m～5.50m, the passenger under highest running speed of train 80～100km/h condition substantially without significant discomfort; But after train running speed surpasses 100km/h, because aerodynamic effects, the uncomfortable situations such as tinnitus, otalgia will appear in the passenger.
Existing " Engineering Project Construction standard " (build mark 104-2008), " metro design code " the urban rapid railway traffic specification speed of service that explicitly points out train such as (GB50157-2003) are not higher than 100km/h, therefore after urban rapid railway traffic train running speed is higher than 100km/h, human comfort standard in the train driving process, how to guarantee comfort level, the requirements of track traffic inner space etc. all can be complied with without certificate, more without specific requirement, same external also without experience that can reference.
The utility model content
Technical problem to be solved in the utility model provides the circular prefabricated reinforced concrete liner structure of a kind of shield tunnel, when satisfying structure stress, shield method requirement, passenger's human comfort requirement in the time of can satisfying highest running speed of train 120km/h.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
The circular prefabricated reinforced concrete liner structure of shield tunnel of the present utility model, it is characterized in that: this tunnel lining is formed by connecting by individual layer annular prefabricated reinforced concrete shield structure ring along the circuit bearing of trend, individual layer annular prefabricated reinforced concrete shield structure ring is assembled by prefabricated unit body hoop, the interior diameter of individual layer annular prefabricated reinforced concrete shield structure ring is 6.00m, external diameter is 6.70m, and ring width is 1.50m.
The beneficial effects of the utility model are, can satisfy the passenger under highest running speed of train 120km/h condition substantially without the human comfort requirement of significant discomfort, and satisfy structure stress, shield method structural requirement.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, the circular prefabricated reinforced concrete lining structure of shield tunnel of the present utility model, tunnel lining is formed by connecting by individual layer annular prefabricated reinforced concrete shield structure ring along the circuit bearing of trend, individual layer annular prefabricated reinforced concrete shield structure ring is assembled by prefabricated unit body hoop, the interior diameter of described individual layer annular prefabricated reinforced concrete shield structure ring is 6.00m, external diameter is 6.70m, and ring width is 1.50m.
According to the characteristics of domestic city rail rapid transit civil works, determine that the running tunnel that highest running speed of train that shield method is built reaches 120km/h is individual layer annular prefabricated reinforced concrete structure.Adopt maximum pressure changing value in the single time interval as the human comfort index, railway car inner air pressure changing value in the 3s is not more than 800Pa as the basic demand of human comfort, actual conditions and operation characteristic according to domestic city rail rapid transit train, rail transit train is sealed index be taken as 0s, when the minimum interior diameter in circular interval tunnel reaches 6.00m, get under the 0s condition at highest running speed of train 120km/h, train envelope index, can satisfy the basic demand of human comfort.
With reference to Fig. 1, described prefabricated unit body comprises the module unit 11 that binds, three calibrated bolck unit 12,13,16, two adjacent block unit 14,15, every individual layer annular prefabricated reinforced concrete shield structure ring is assembled by 6 (form of 3+2+1) prefabricated unit bodies.The central angle of module unit 11 correspondences that bind is 20.5 °, and three calibrated bolck unit 12,15,16 each self-corresponding central angle are 67.5 °, and two adjacent block unit 13,14 each self-corresponding central angle are 68.5 °.Each prefabricated unit body has corresponding hoop bolt hole 17, is connected to annulus by the arch screw bolt that passes hoop bolt hole 17 between each prefabricated unit body.Each prefabricated unit body has longitudinal bolt hole 18, is connected to integral body by the arch screw bolt that passes longitudinal bolt hole 18 between the adjacent monolayer annular prefabricated reinforced concrete shield structure ring.
See figures.1.and.2, the width of shield structure ring on line direction is wedge shape and distributes, and to satisfy the needs of 3 in Curve Segment shield reconstruct zygonema road and correction, wedge shape amount 36mm can realize match and the correction of minimum planes radius 300m curved section.
Some principles of the above circular prefabricated reinforced concrete liner structure of the utility model shield tunnel that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
