Abstract

The utility model discloses a duct piece semi continuous seam spliced shield pipeline which comprises a pipeline body. The pipeline body is a hollow circular cylinder formed by splicing a plurality of duct pieces in same standard, and continuous seams are formed at the upper edge and the lower edge of each row of duct piece in an abreast mode in the longitudinal direction of the pipeline body. Adjacent duct pieces are connected in stagger in the peripheral direction of the pipeline body. 8 or 10 duct pieces are arranged on each ring of the periphery of the pipeline body. Adjacent duct pieces are fixed through a bolt. The pipeline conducts semi continuous seam splicing on shield duct pieces, longitudinal rigidity of the pipeline is big, anti-floating performance and hole tail slip casting of the pipeline are excellent.

Description

The shield structure pipeline of a kind of section of jurisdiction half straight joint splicing
Technical field
The utility model belongs to field of engineering technology, is specifically related to the shield structure pipeline of a kind of section of jurisdiction half straight joint splicing.
Background technology
Quickening along with Urbanization in China; Increasing city begins to build subway, and the main employing shield structure technology of building of subway is carried out, the excavation in shield structure technology collection tunnel; Supporting; The section of jurisdiction splicing is integrated, is a kind of safe, form of construction work easily and fast, and shield-tunneling construction finally is to form final tunnel after becoming shield structure pipeline with pipe sheet assembling.
At present; The common structure of shield structure pipeline is divided into two kinds in the pipeline (referring to Fig. 2) that pipeline (referring to Fig. 1) that straight joint is spliced to form and the fissure of displacement be spliced to form according to the mode difference of section of jurisdiction splicing; These two kinds of pipelines respectively have pluses and minuses, and their common shortcomings are that the longitudinal rigidity of pipeline is less, and endnote slurry in hole can form bigger shear stress to the section of jurisdiction after the section of jurisdiction splicing is accomplished; Cause destruction easily, also easily the bolt that connects in the pipeline is formed shear failure pipeline configuration.Therefore, studying the bigger shield structure pipeline of a kind of longitudinal rigidity is very to be necessary.
Summary of the invention
To defective that exists in the above-mentioned prior art or deficiency; The purpose of the utility model is; The shield structure pipeline of a kind of section of jurisdiction half straight joint splicing is proposed; This pipeline carries out half straight joint to shield duct piece and is spliced to form, and makes that the pipeline longitudinal rigidity is bigger, on pipeline anti-floating property and hole endnote slurry, very big advantage is arranged.
In order to achieve the above object, the utility model adopts following technical solution:
The shield structure pipeline of a kind of section of jurisdiction half straight joint splicing; It is characterized in that; Comprise pipe main body, this pipe main body is the hollow circular cylinder that the many sections of jurisdiction by same size are spliced, said pipe main body vertically on each comb sheet on the concordant formation straight joint of lower limb; The fissure of displacement joins between the adjacent section of jurisdiction of the circumferencial direction of said pipe main body.
Every circle is arranged with 8 or 10 sections of jurisdiction on the circumference of said pipe main body.
Pass through bolt between the adjacent section of jurisdiction.
Compare traditional shield structure pipeline, the utility model has its special advantages:
1) the pipeline longitudinal rigidity is big, on pipeline anti-floating property and hole endnote slurry, very big advantage is arranged.
2) the section of jurisdiction specification is identical, and is easy to make, can combination in any during assembly unit.
3) assembly unit uses bolt specification identical, does not need regular collocation.
Description of drawings
Fig. 1 is the shield structure pipeline that traditional section of jurisdiction straight joint splices.
Fig. 2 is the shield structure pipeline that traditional section of jurisdiction fissure of displacement splices.
Fig. 3 is the section of jurisdiction half straight joint splicing shield structure pipeline of the utility model.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further explained.
The specific embodiment
As shown in Figure 3; The shield structure pipeline of the section of jurisdiction half straight joint splicing of the utility model; Comprise pipe main body; This pipe main body is the hollow circular cylinder that the many sections of jurisdiction 1 by same size are spliced, pipe main body vertically on each comb sheet on the concordant formation straight joint 2 of lower limb (promptly forming the vertical masonry joint of a perforation); The fissure of displacement join (be that the section of jurisdiction is interlaced, the edge of section of jurisdiction does not form a seam) between the adjacent section of jurisdiction 1 of the circumferencial direction of pipe main body.On the circumference of pipe main body, every circle is arranged with 8 or 10 sections of jurisdiction 1, passes through bolt between the adjacent section of jurisdiction 1.The dimensional parameters of section of jurisdiction 1 is according to the design that needs of the shield structure pipeline of actual subway tunnel.

Claims (3)
