Problems solved by technology

The support structure of this patent application is mainly used in tunnel lining projects. When the support structure is spliced ​​along the axial direction, its side flanges and their connecting bolts are exposed on the inner side of the tunnel, which is easy to collide with or scratch the internal passing vehicles. The damage to the vehicle and the supporting structure is relatively large; at the same time, the s

Example Embodiment

[0021] The technical scheme of the present invention will be further described below in conjunction with the drawings.

[0022] The splicing structure of the present invention includes the unit plates 101 being assembled in the circumferential direction to form a pipe section 102, which is spliced ​​along the axial direction to form a tunnel lining or culvert 100; wherein, when the pipe section 102 is spliced ​​in the axial direction, adjacent unit plates The contact ends of the sheet 101 each have a folded edge 104 or a hollow cavity structure 110 that is turned to the outside of the pipe section. The cross section of the hollow cavity structure 110 is closed and the adjacent folded edge 104 or the hollow cavity structure 110 is in contact The surface is the splicing connection surface, such as Picture 9 , 10 Shown. Preferably, the contact surface can be connected by a workpiece such as a bolt. Since the hemming or hollow cavity structure is located outside of the tunnel, culv...

Abstract

The invention discloses a splicing structure used for a combined type tunnel lining, a culvert or a comprehensive pipe gallery. Unit plates are spliced into pipe joints in a circumferential direction; the pipe joints are axially spliced to form the tunnel lining, the culvert or the comprehensive pipe gallery, wherein when the pipe joints are axially spliced, contact end parts of adjacent unit plates are provided with folding sides folded to the outer sides of the pipe joints or hollow cavity structures with cross sections peripherally closed; and the contact surfaces of the adjacent folding sides or the hollow cavity structures are spliced connecting surfaces. The splicing structure is not exposed to the inner part of the tunnel or the culvert, does not affect passing vehicles therein and avoids collision or scratches; and meanwhile, the spliced part of the tunnel or the culvert inner wall is smooth and attractive, the inner passing space is increased, the section area is reduced, the engineering excavated volume is reduced, and the construction period is shortened.

Description

Technical field [0001] The invention discloses a pipeline splicing structure, in particular to a splicing structure used for combined tunnel lining, culvert or comprehensive pipe gallery. Background technique [0002] The applicant has been committed to the research, application and infrastructure engineering of steel structures and steel-concrete composite structures, and has applied for a number of patents, including a steel-concrete composite tunnel lining support structure and its production And construction method", the invention patent application with application number 201510600685.8. The supporting structure of the patent application is mainly used in tunnel lining projects. When the supporting structure is spliced ​​along the axial direction, its side flanges and their connecting bolts are exposed on the inside of the tunnel, which is easy to collide or scratch with internal vehicles. The damage to the vehicle and supporting structure is relatively large; at the same t...
