Making and the assembling process of general wedge shape shield duct piece of the present utility model are as follows:
1) section of jurisdiction type of design
(1) section of jurisdiction wedge shape amount setting
In conjunction with the technical condition in this tunnel, for the ease of construction, section of jurisdiction pattern have employed universal wedge-shaped segment, and its wedge shape amount calculates by the smallest curve radius of shield tunnel circuit and determines after considering.Reinforced concrete lining layer adopts C50 high performance concrete, and concrete impervious grade is P12, makes shaping in high accuracy punching block.During lining cutting typesetting, all matching (common fitting error <10mm, local 15mm) is carried out, to meet the requirement of line design with preferred best lining cutting arrangement as calculated to different easement curves, circular curve segment.
(2) thickness of section of jurisdiction
The thickness of section of jurisdiction is generally 5% ~ 6% of section of jurisdiction external diameter, according to structural calculation and reference class like engineering experience, lining thickness adopts 500mm.
(3) piecemeal of section of jurisdiction
The piecemeal of lining cutting annulus mainly from the viewpoint of section of jurisdiction transport capacity, make assembled convenience, structure stress etc., Lining Ring loopful is divided into 8+1 pattern, is namely made up of one piece of block K that binds, two pieces of adjacent block B and six piece of calibrated bolck A.Namely block form is 6A (43.2 °)+2B(43.2 °)+K(14.4 °), in a ring, longitudinally adopt 25 to wait central angle to arrange.
(4) width of section of jurisdiction
Generally, section of jurisdiction ring width is determined according to the smallest curve radius of shield tunnel, Shield-type machinery structure and correlation engineering experience, adopts the ring width of 1800mm in this utility model.
2) pipe sheet assembling
Section of jurisdiction adopts staggered joint erection, and the block that binds (A block) adopts the assembling method first overlapping 2/3 ring width radial direction and push to, longitudinally insert.For ensureing the stress performance that fabricated construction is good, the arrangement works condition providing according calculation to suppose, lining cutting is assembled must reach following precision:
(1) allowable error of erecting ring in whole: circumferential weld gap≤1.0mm; Longitudinal joint gap be 2 ± 2 0mm(wherein 2mm be power transmission liner), hoop bolt hole malalignment corresponding to lining cutting is less than 1mm.
(2) lining cutting is assembled into the level of ring, vertical diameter deviation≤2 ‰ D(section of jurisdiction external diameters).
3) ring longitudinal joint structure
From being conducive to improving seam rigidity, controlling pipe sheet assembling dislocation consideration, this section of jurisdiction contact surface longitudinal joint establishes convex-concave tenon, and circumferential weld does not establish convex-concave tenon.Elastic sealing gasket groove is established in contact surface outer arc side between section of jurisdiction ring and ring and between block and block, and filleting groove is established in inner arc side.Ring is connected with 50 longitudinal bolts with interannular, can adapt to certain longitudinal strain, tunnel longitudinal strain can be controlled in the scope meeting train operation and waterproof requirement again.Block is connected with 2 hoop bolts with interblock, effectively can reduce longitudinal joint and open and malformation.Hoop bolt, longitudinal bolt all adopt nanometer composite powder zinc impregnation preservative treatment, and anticorrosive coat thickness is not less than 50 microns.
Every endless tube sheet of the present utility model is all by general wedge-shaped design, and by changing the erection method of section of jurisdiction, a set of section of jurisdiction can be applicable to straightway and curved section completely.Time assembled from calibrated bolck (A block), the left and right sides alternately assembled standard section of jurisdiction, then assembled adjacent block (B block), the finally assembled block that binds (K block) successively, section of jurisdiction adopts staggered joint erection, and the block that binds adopts the assembling method first overlapping 2/3 ring width radial direction and push to, longitudinally insert.By adjustment each section of jurisdiction angle time assembled, and the position that A, B, K block is assembled, be namely applicable to straightway and curved section.General wedge shape shield duct piece structure of the present utility model, highly versatile, piecemeal are succinct, simply assembled, can save mould, simplify section of jurisdiction making, assembled program, thus reduce cost, reduce construction investment.
