Splicing structure used for combined type tunnel lining, culvert or comprehensive pipe gallery

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...

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 structure occupies and reduces the internal passage space of the pipeline, increases the thickness of the entire structural layer, and then increases the area of ​​the excavation section, increases the amount of excavation, and prolongs the construction period ; Not only that, but the structure needs to be inspected frequently to see if the bolts are loose, which also affects the appearance, see below Figure 5 , 6
