Problems solved by technology

[0002] At present, when there is a section with a small curvature radius in a shield tunnel, the segment type is an assembly of straight-line ring segments and curved ring segments. Different wedge-shaped rings are used to fit the tunnel axis in curves and vertical curves; left-turn, straight-line, right-turn and special rings need to be designed and processed for the entire tunnel. Therefore, it is not conducive to the precise control of the tunnel axis during shield construction

Embodiment Construction

[0014] Such as figure 1 and figure 2 A general-purpose wedge-shaped segment ring for a shield tunnel with an ultra-small curvature radius is shown, including a segment ring main body 10, the segment ring main body 10 is a ring body, and the segment ring main body 10 is assembled and combined by six wedge-shaped segments; The 6 wedge-shaped segments are the first wedge-shaped segment 11, the second wedge-shaped segment 12, the third wedge-shaped segment 13, the fourth wedge-shaped segment 14, the fifth wedge-shaped segment 15, and the sixth wedge-shaped segment 16; The piece main body 10 circles the central point, starts from the 12 o'clock position in the form of a clock, and divides into 24 scales at 15 degrees clockwise. In the unfolded plan view of the ring main body 10, the width of the segment ring main body 10 corresponding to the scale of the bisector 200 to the scale 209 gradually expands, and the width of the segment ring main body 10 corresponding to the scale of t...

Abstract

The invention provides a universal wedge-shaped pipe piece ring of a shield tunnel with a super-small curvature radius. The universal wedge-shaped pipe piece ring comprises a pipe piece ring body which is a torus and formed by combining six wedge-shaped pipe pieces in a splicing mode; starting from the 12 o'clock position in a clock mode, the pipe piece ring is evenly divided into 24 scales around the center point of the pipe piece ring clockwise by 15 degrees, and even division line mark numbers of the evenly divided 24 scales are 200-224 scales; in an unfolded plan of the pipe piece ring, the width of the pipe piece ring body corresponding to the even division line mark numbers from 200 to 209 scales is enlarged gradually, the width of the pipe piece ring body corresponding to the even division line mark numbers from 209 to 220 scales is reduced gradually, and the pipe piece ring body corresponding to the even division line mark numbers from 220 to 224 scales is enlarged gradually; various parameters of the pipe piece ring body include wedge amount and are determined according to various concrete parameters of the shield tunnel. The universal wedge-shaped pipe piece ring is simple in structure and convenient to splice, and not only meets the requirement of a straight line segment, but also can be used for a curved segment with the super-small curvature radius.

Description

technical field [0001] The invention relates to a general-purpose wedge-shaped segment ring for a shield tunnel, in particular to a general-purpose wedge-shaped segment ring for a shield tunnel with an ultra-small curvature radius. Background technique [0002] At present, when there is a section with a small curvature radius in a shield tunnel, the segment type is an assembly of straight-line ring segments and curved ring segments. Different wedge-shaped rings are used to fit the tunnel axis in curves and vertical curves; left-turn, straight-line, right-turn and special rings need to be designed and processed for the entire tunnel. Therefore, it is not conducive to the precise control of the tunnel axis during shield construction. Contents of the invention [0003] In view of the above-mentioned defects of the existing segment technology, the present invention provides a general-purpose wedge-shaped segment ring for shield tunneling with an ultra-small radius of curvatur...
