Embodiment
Technical scheme is described further below in conjunction with the accompanying drawings.
As shown in figure 9, the arched conduit of the present invention, including by being located at the unit sheet bar 101 of top and bottom and two sides respectively
Assembly forms arch tube coupling, and the arch tube coupling is assembled vertically to form arched conduit；Wherein, the unit sheet bar 101 is to pipe
The obtuse angle of circumferential connection is formed between the arc-like sheet of arch camber on the outside of road, adjacent cells plate.
Wherein, both sides unit sheet bar and upper unit sheet bar are arc-like sheet, and lower unit plate is inverted arch shape, as shown in Figure 9.
The length of single-unit tube coupling of the present invention is up to 10-15 meters, as long as traffic condition is permitted, length can be with longer, and so whole pipeline connects
Seam is reduced, better tightness；By obtained arch tube coupling, assembly forms arched conduit vertically；Wherein, the unit sheet bar 101
There are the structure of hollow cavity structure 110, and the cross-sectional perimeter closure of the hollow cavity structure 110 in outside and/or inner side.It is preferred that
, cavity has certain length, and two ends can be with insertion or one end closing, one end open.The hollow cavity of the closed type cross section
Body structure is than the hollow cavity structure of open type cross section, and torsional rigidity is higher, resist vertical unstability ability stronger, in addition pipeline
For domes, therefore, the vertical bearing capacity of pipeline is further strengthened.Meanwhile, the pipeline of domes, it is internal net
The utilization rate in space is improved.
Above-mentioned hollow cavity structure 110 can individually be located on unit sheet bar 101, such as Fig. 1 (a), 1 (b), 1 (o) -1
(r) shown in.
Wherein unit sheet bar is made up of metallic plate, and hollow cavity structure 110 can be formed by the metallic plate bent upon itself, curved
The shape of cross section of folding can be for rectangle, circle etc., and the seam that will be formed between hollow cavity structure 110 and unit sheet bar 101
Gap is welded, and such as Fig. 1 (c), 1 (d), 1 (e) are shown.Raised 103 shape can also be bent to form by metallic plate 106, with sheet material or pipe
Material combines to form hollow cavity structure 110 with the projection 103, such as shown in Fig. 1 (f) -1 (n), wherein, the cavity shape being bent to form
Shape can be groove profile, arc, semicircle etc., and sheet material used can be steel plate, channel-section steel, C-type steel, curved plate etc..
Can to the present invention hollow cavity structure 110 in fill concrete, can be first to the sky on unit sheet bar during filling
The concrete perfusion of heart cavity body structure 110, it is then assembled again；Or by the hollow cavity structure head and the tail phase on adjacent cells plate
Connect, to form continuous hollow cavity structure, assembly forms tube coupling overall perfusion again, and concrete filling is accordingly opened up at the top of tube coupling
Orifice and concrete overfolw hole.Wherein, reinforcing bar can be set up in hollow cavity structure 110 while fill concrete.This
Invention make use of concrete and/or the superior bearing capacity of reinforcing bar and steel pipe to the encapsulation of concrete, can be at utmost
Ground delays the generation and extension of hollow cavity inside configuration distress in concrete, further enhances the vertical bearing capacity of pipeline.
When the arch tube coupling splices vertically, the contact end of adjacent cells plate 101 is bent to form flanging 104, excellent
Choosing, the flanging 104 is folded to the outside of arch tube coupling, can reduce in pipeline the collision of vehicle etc. and wall or scratch, adjacent folding
The contact surface on side 104 is splicing joint face, for example can be using flange bolt connection, shown in such as Fig. 8 (b).Or adjacent cells plate
The contact end of piece has hollow cavity structure 110, and the hollow cavity structure 110 can be bent to form by unit sheet bar or in unit
Individually welded on plate, the contact surface of adjacent hollow cavity body structure 110 is splicing joint face, for example, can be opened up on the contact surface
Bolt hole, and bolt handle hole 113 is opened up on another surface of hollow cavity structure close to the bolt hole, instrument is grasped from bolt
Make hole 113 to stretch into for fastening bolt in hollow cavity structure 110, after bolt is tightened, retrieving tool, then blocked with port lid 114
Bolt handle hole 113, to prevent during concrete perfusion, concrete overflows through bolt handle hole 113 subsequently into hollow cavity structure,
Such connecting bolt is no longer exposed in pipeline, will not space-consuming, influence attractive in appearance, therefore call it as concealed connection, such as
Shown in Fig. 8 (c).It is of course also possible to the contact end of adjacent cells plate directly be welded, shown in such as Fig. 8 (a).
The unit sheet bar 101 of the present invention can also be spliced by metallic plate 106 and metal tube 107, such as Fig. 2 (a) -2 (e)
It is shown；Or be spliced side by side by metal tube 107, its cross section is a chain of structure, and such as Fig. 3 (a), 3 (b), 3 (c) are shown；Or
Person is mutually fastened by corrugated plating 108 and forms the unit sheet bar with hollow cavity structure 110, shown in such as Fig. 4 (a)；Or by c-type
Steel, channel-section steel, I-steel, arc-shaped steel, angle steel or corrugated plating 108 fasten with flat board 109 and form the list with hollow cavity structure 110
Shown in first plate, such as Fig. 4 (b).Straight sheet material is bent to form the sheet material with shapes such as arc, ripple type, groove profiles above
Can be with the vertical bearing capacity of adding unit plate.
When above-mentioned arch tube coupling splices vertically, the contact end of adjacent cells plate 101 has metal tube 107 or hollow
Cavity body structure 110, and adjacent metal pipe 107 or the contact surface of hollow cavity structure 110 are splicing joint face, for example, can be connect at this
Bolt hole is opened up in contacting surface, then using above-mentioned concealed connected mode.Likewise, can as needed in metal tube 107 or
Fill concrete in hollow cavity 110, or reinforcing bar is set in the metal tube 107 or hollow cavity structure 110 and fills mixed
Solidifying soil.
When the assembly of said units plate 101 forms arch tube coupling, a pair of flanged plates are passed through between adjacent cells plate 101
115 connections, as illustrated in figs. 5-7.Wherein, the end of each unit sheet bar 101 is equipped with a flanged plate 115, for example, can be
Welding, and concrete flow orifice 116 is opened on flanged plate 115, the shape of the concrete flow orifice 116 can be with hollow cavity knot
