Description
Technical field
The present invention relates to full-face TBM, be especially for the section of jurisdiction three-dimensional-structure of Shield TBM.
Background technology
Section of jurisdiction is the permanent lining, secondary lining structure of shield method tunnel, and tunnel is played lining cutting effect by section of jurisdiction on the one hand, provides for the driving of Shield TBM on the other hand and supports.Therefore, the quality of section of jurisdiction three-dimensional-structure design is huge on construction speed and the water resistance impact of tunnel.The section of jurisdiction three-dimensional-structure being presently used for shield method tunnel is broadly divided into hexagon section of jurisdiction and two kinds, wedge shape section of jurisdiction.One, during hexagon pipe sheet assembling, one ring is made up of four pieces of sections of jurisdiction, advantage is that less piecemeal simplifies assembling process and process, and the assembled position of every piece of section of jurisdiction is fixed, and is conducive to the conveying track of advancing equipment on bottom tube sheet, facilitate the transport of equipment, substantially increase construction speed；The deficiency existed is when tunnel footpath is bigger, and less piecemeal makes the volume and weight of monolithic section of jurisdiction all relatively big, adds the transport of section of jurisdiction and assembled difficulty, and then the transporting equipment of section of jurisdiction and manufacture and the construction speed of assembled equipment are caused bad impact；And hexagonal tube sheet hoop seam is wedge angle with radial slot intersection, and time assembled, sealing is difficult to press closely, and water resistance is poor.Two, the advantage of wedge shape section of jurisdiction is in that: piecemeal is flexible, it is possible to have different piecemeals according to the size in tunnel footpath；Correction when on the other hand the wedge shape amount of hoop contributes to pipe sheet assembling and turning；Taper pipe sheet hoop seam is more smooth with radial slot intersection simultaneously, is prone to compacting smooth time assembled, and water resistance is good；The deficiency existed is: wedge shape section of jurisdiction realizes correction by hoop wedge shape amount and ring and ring rotary assembling and turns, therefore when turning correction, the position of every piece of section of jurisdiction needs accurate calculation, cause the difficulty adding assembling process on the one hand, and easily cause radially straight joint, structure is unfavorable；The assembled position of every piece of section of jurisdiction is not fixed on the other hand, and inconvenience advancing equipment conveying track, thus causing unfavorable factor to equipment conveying and construction speed.
Summary of the invention
Present invention aim at providing a kind of monocycle section of jurisdiction three-dimensional-structure for Shield TBM.
For achieving the above object, the present invention takes following technical proposals:
Monocycle section of jurisdiction three-dimensional-structure for Shield TBM of the present invention, including monocycle section of jurisdiction body；Described monocycle section of jurisdiction body is made up of four or six standard sections of jurisdiction, a bottom tube sheet and a section of jurisdiction of binding；The horizontal projection profiles line in inside arc face, described standard section of jurisdiction constitutes parallelogram, and inside described bottom tube sheet, the horizontal projection profiles line of cambered surface constitutes isosceles trapezoid, described in the horizontal projection profiles line of cambered surface inside section of jurisdiction that binds constitute and fall isosceles trapezoid；The described radial slot being connected mutually between the radial slot, bottom tube sheet and the standard section of jurisdiction that are connected mutually between the radial slot, standard section of jurisdiction and the standard section of jurisdiction that are connected mutually between section of jurisdiction with standard section of jurisdiction that binds all becomes 12 °～15 ° angles with the sagittal plane of described monocycle section of jurisdiction body.
As tunnel diameter 6m, described monocycle section of jurisdiction body is made up of four standard sections of jurisdiction, a bottom tube sheet and a section of jurisdiction of binding；The central angle alpha of described standard section of jurisdiction is 58 °, and the central angle β 1 of described bottom tube sheet and the central angle β 2 of section of jurisdiction of binding is 64 °.
When tunnel diameter > 6m time, described monocycle section of jurisdiction body is made up of six standard sections of jurisdiction, a bottom tube sheet and a section of jurisdiction of binding；The central angle alpha of described standard section of jurisdiction is 44 °, and the central angle β 1 of described bottom tube sheet and the central angle β 2 of section of jurisdiction of binding is 48 °.
Advantage of the present invention be mainly reflected in following some:
1, section of jurisdiction piecemeal is flexible, and as tunnel diameter 6m, monocycle section of jurisdiction body is made up of four standard sections of jurisdiction, a bottom tube sheet and a section of jurisdiction of binding；When tunnel diameter > 6m time, monocycle section of jurisdiction body is made up of six standard sections of jurisdiction, a bottom tube sheet and a section of jurisdiction of binding；Therefore body assembling process in monocycle section of jurisdiction is simple, and the impact by tunnel diameter is less.
2, the assembled position of each section of jurisdiction is fixed, and bottom tube sheet is prone to the conveying track of advancing equipment, facilitates equipment and the transport of machinery, and then the lifting of construction speed is significant.
3, the monocycle section of jurisdiction body hoop seam after assembly is comparatively smooth with radial slot intersection, is prone to compacting smooth, has good water resistance time assembled.
