The embodiment of the utility model provides a rectangle shield tunnel lining ring 1, its section is the rectangle or roughly is the rectangle, of course, conventionally, it still has certain radian (for example four bights are the fillet, vault and hunch end have certain radian etc.), and this is the conventional cognition in this field to not limit its protective scope with the geometric sense of its literal.
As shown in fig. 4-9, the lining ring 1 comprises two capped pipe pieces 11 and a plurality of standard pipe pieces 12, wherein each standard pipe piece 12 corresponds to two longitudinal seams 14, one longitudinal seam 14 is parallel to the longitudinal direction of the tunnel/the longitudinal axis of the tunnel at the corresponding position, and the other longitudinal seam 14 forms an included angle with the longitudinal direction of the tunnel/the longitudinal axis of the tunnel at the corresponding position; the two capped duct pieces 11 are wedged in opposite directions with at least one of the standard duct pieces 12 in between.
It will be appreciated that the capping segment 11 described above still employs a conventional wedge-shaped block structure, which may have a certain amount of curvature/camber, and which is preferably shaped as an isosceles trapezoid when expanded into a plane; for the wedging direction described above, i.e. the insertion direction in the longitudinal direction of the tunnel.
The modular tube sheet 12 may be configured accordingly to the location of use, for example, for a modular tube sheet 12 at a corner, it may be of generally L-shaped configuration, and may have a curvature that is preferably right trapezoidal when expanded into a flat configuration, with parallel top and bottom edges corresponding to the two circumferential seam edge portions thereof, and right side and oblique edges corresponding to the two longitudinal seam 14 edge portions thereof.
Based on the structure of the lining ring 1, the mirror image assembly of the lining ring 1 of the rectangular shield tunnel can be realized, namely, each segment is assembled relative to the mirror image of the vertical symmetrical plane of the lining ring 1, and the segment assembly structures on two sides of the vertical symmetrical plane of the lining ring 1 are the same. Preferably, the capping segments 11 are wedged into the arch top or the arch bottom, and because the two capping segments 11 are controlled to be not adjacent, the two capping segments 11 are preferably arranged oppositely up and down, and each capping segment 11 is symmetrical relative to the vertical symmetrical plane of the lining ring 1.
In fig. 4 is shown a preferred embodiment of the application of a 6-segment lining ring 1, i.e. 4 standard segments 12; but not limited to the block-type manner, the required ring shape can be assembled and fitted, and an even number of standard pipe pieces 12 is preferred.
Example two
As shown in fig. 5-9, the embodiment of the utility model provides a rectangle shield tunnel lining structure, including a plurality of rectangle shield tunnel lining ring 1 that above-mentioned embodiment provided, each lining ring 1 is vertically spliced in proper order along the tunnel.
Based on the structure of the lining ring 1 of the rectangular shield tunnel provided by the first embodiment, the rotation mode of the lining ring is changed from conventional rotation around the longitudinal axis of the tunnel to rotation around the vertical axis of the tunnel, and the lining ring is assembled through seams.
Thus, the rectangular shield tunnel lining structure can be fitted with a tunnel plane curve only by adopting one wedge ring (namely, the rectangular shield tunnel lining ring 1 adopts a certain wedge amount), and specifically:
(1) as shown in fig. 5 and 6, in the straight tunnel segment, the capping segments 11 of two adjacent rectangular shield tunnel lining rings 1 are correspondingly abutted one by one, and the wedging directions of the two abutting capping segments 11 are opposite. I.e. two adjacent lining rings 1 are rotated 180 deg. around the vertical axis of the tunnel to fit the straight longitudinal axis of the tunnel.
Obviously, when the rectangular shield tunnel is a full straight tunnel, the lining ring 1 can also eliminate the setting of the wedge amount.

The construction process of the rectangular shield tunnel lining structure is approximately as follows:
(1) determining the ring width and wedge amount of the lining ring 1 according to the plane (or longitudinal section) design parameters of the rectangular shield tunnel;
(2) dividing lining ring blocks and numbering 13 according to the structural section of the rectangular shield tunnel;
(3) determining the positions of the two capping segments 11, wherein the two capping segments 11 are not adjacent;
(4) the shape of the remaining segments (i.e., the standard segment 12) except for the capped segment 11 is determined.
(5) Manufacturing a duct piece;
(6) assembling pipe pieces:
for a linear section, two lining rings 1 are used as a group, the two lining rings 1 in the same group are used, wherein one lining ring 1 rotates 180 degrees around a vertical axis of a tunnel relative to the other lining ring 1 so as to fit a linear longitudinal axis of the tunnel;
for a curve section, when the curve radius is matched with the wedge-shaped amount of the lining ring 1, all the lining rings are assembled by adopting the same-direction lining ring 101; when the curve radius is not matched with the wedge amount, a plurality of equidirectional lining rings 101+1 reverse lining rings 102 which rotate 180 degrees around the vertical axis of the tunnel are assembled in a combined mode to fit the curve longitudinal axis of the tunnel;
in each lining ring 1, two capping segments 11 determine that one of the capping segments 11 is finally assembled to cap according to the arrangement mode of the lining ring 1, and the other capping segment is used as the first assembly block of the lining ring 1.
The lining structure of the rectangular shield tunnel provided by the embodiment only adopts the lining ring 1, the segment is simple to manufacture, and the construction and management are convenient. Except a small number of cross-shaped seams 15 (mainly appearing in a spliced structure of which one lining ring 1 rotates 180 degrees around a vertical axis of the tunnel relative to the other lining ring 1), the other seams are T-shaped seams 16, so that the waterproof performance of the tunnel is obviously improved.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
