Specific embodiment
Below in conjunction with the accompanying drawings technical scheme is described further.
As shown in Figure 6 and Figure 8, the present invention it is a kind of with circumferential obtuse angle connection box pipeline, including by respectively be located at it is upper,
The unit sheet bar 101 of lower and two sides is circumferentially assembled to form unit tube coupling 102, and the unit tube coupling 102 is assembled vertically to be formed
Box pipeline；The unit sheet bar 101 is the arc-shaped wave card of the arch camber on the outside of box pipeline, its ripple lines and box pipeline
Axle center is perpendicular, and the obtuse angle of circumferential connection is formed between adjacent cells plate 101；Wherein, the unit sheet bar 101 is circumferentially spelled
When connecing, the contact end of adjacent cells plate 101 is provided with adpting flange 103, and adjacent adpting flange 103 to splice joint face,
As shown in figure 3, wherein adpting flange 103 is flat flange or angle steel flange, in unit sheet bar 101 and adpting flange 103
Circumferential connecting hole is opened up on circumferential Mosaic face, and realizes quickly connecting by bolt, install convenient, significant increase construction speed,
As shown in Figure 10.Wherein, as illustrated in fig. 7 and fig. 10, the flange face of flat flange and the cambered surface of unit sheet bar are angled.
Wherein angle steel flange is L-type plate, and one side and the unit sheet bar 101 of the L-type plate are inter-connected via a bolt joint；Wherein, the list
When first plate 101 circumferentially splices, adjacent L-type plate is inter-connected via a bolt joint, as shown in figure 11.The box pipeline is circumferentially adopted
Flat flange or angle steel flange connection, integral construction progress is greatly accelerated, when connecting especially with angle steel flange, corner stress
Concentration zones stressing conditions are greatly improved, it is to avoid adpting flange is with the single form being welded to connect of unit sheet bar in dynamic load work
Weld cracking under condition and cause pipe structure destruction etc. phenomenon.
The unit sheet bar 101 for being located at upper and lower and two sides in the present invention respectively has at least one radian, four module unit plates
Piece can be the plate of same radian, can also be that the plate of two kinds, three kinds or four kinds different radians is constituted.Wherein, corrugated plating by
Metallic plate is constituted, and the metallic plate bent upon itself forms projection；Or metallic plate is bent to form convex shape, with sheet material or tubing with should
Combination of protrusions forms hollow cavity structure；Or be spliced by metallic plate and metal tube；Or by C-type steel, channel-section steel, I-steel,
Arc-shaped steel, angle steel or corrugated plating and metallic plate fasten to be formed with hollow cavity structure.The present invention can be in above-mentioned hollow cavity
Filling concrete, or reinforcing bar is arranged in the hollow cavity and concrete is filled.The ripple of the corrugated plating of inventive pipeline
Height value and cross sectional moment of inertia can be very high, it is to avoid pipe diameter is less or during less radius of arc transition section, it is difficult to curved
A bent difficult problem into required radian, so as to the radian for also causing plate is no longer limited by pipe diameter and span, is production system
Make offer to know clearly facility.
The circumferential connecting portion of adjacent cells plate adopts non-arc transition type of attachment, on-right angle type of attachment, but
By obtuse-angulate connected mode connection between unit sheet bar and unit sheet bar.
As shown in figure 12, traditional arc transition type of attachment is higher for fabrication and processing technological requirement, and to adjacent cells
The circular arc coherence request of plate is high, is otherwise difficult to install, it is often more important that：When wave height it is higher, pipe diameter it is less or
When the radius of arc transition section is less, just it is difficult to bend to required radian, so as to limit big wave height, big the moment of inertia ripple
The use of plate.And pipeline Impact direction is plate ring direction in arc transition type of attachment.As shown in figure 13, right angle connection
Form cannot use the common Force principle of pipeclay, and upper load by the transmission of junction all by two heel posts holding
Receive, column bearing capacity requires high.
As shown in figure 14, in angle type of attachment of the invention, each plate Impact direction is also plate ring direction, but by
Then obtuse angle connection, non-arc transition connection, connects the Impact direction in corner, and as shown in figure 14, sidepiece backfill is to top board
Extruding so that the side plate of connection corner portion has the larger component lifted upwards to top board, mitigates top lotus suffered by the plate of top
Carry pressure.The vertical pressure of same top plate so that top board has larger lateral thrust in connection corner offside plate, mitigates sidepiece
Sidepiece load pressure suffered by plate, it is seen that with top load under this kind of attachment structure form, can cancel out each other side plate load portion
Divide load, so that overall structure is more they tended to rationally.
The pipeline section is approximate rectangular box-shaped, and its pipeline headroom utilization rate is high, such as dotted portion institute in Fig. 5 and Fig. 9
Show；Wherein unit sheet bar adopts the arcuation corrugated plating of arc-shaped structure, and after corridor body soil body backfill, surrounding backfill is to corridor physical ability
Good package action is formed, in overall structure stress, surrounding soil constitutes an entirety with pipeline configuration, because plate exists
It is circumferentially circular arc, using the common Force principle of pipeclay, integrally-built intensity is maximized with holding capacity.
As shown in Figure 5 and Figure 6, when said units plate 101 circumferentially splices, by week between adjacent adpting flange 103
Connect to attachment structure, the circumferential attachment structure includes the angled connecting plate 104 of bent upon itself, bending angle is sharp
Angle, arranges reinforcement 105 on the inside of the connecting plate 104, trigonometric expression inner chamber is formed between the reinforcement 105 and connecting plate 104.Strengthen
Muscle causes overall structure more to consolidate, while connecting plate can also play certain positioning action, adjacent list during being easily installed
The circumferential connection of first plate, realizes Fast Installation.Present invention utilizes acute angle connecting plate and reinforcement combination have it is superior
Bearing capacity, it is possible to reduce manufacturing cost, realize standardized production, and further enhance integrally-built by force intensity.Such as Fig. 4
Shown, the contact end of said units plate 101 is provided with adpting flange 103, the adpting flange 103 for flat flange,
And flange face is perpendicular with the corrugated surface of unit sheet bar, i.e., flange face is located on the axial line of arc unit sheet bar, such as Fig. 5 institutes
Show.
As shown in figure 1, the present invention opens up the connecting hole 106 for circumferential connection on connecting plate 104, while in cell board
Circumferential connecting hole is offered on the circumferential Mosaic face of piece 101 and adpting flange 103, on the circumferential connecting hole and connecting plate 103
Connecting hole 106 realizes the connection between adjacent cells plate by bolt.
As shown in Fig. 2 the opening 107 for concrete perfusion is opened up on connecting plate 104.Spell in the pin-connected panel piping lane
It is when needing casting concrete after the completion of dress, in order to realize the globality of the insertion between each plate and concrete, corresponding in connecting plate
Position opens up opening, forms continuous hollow cavity structure to realize the circulation of concrete, assembled to form tube coupling, further
Strengthen the vertical bearing capacity of piping lane.
The present invention arranges reinforcing bar, built-in fitting or hook in 102 inwall of unit tube coupling, so as to later stage inside arrangement pipeline
Or flexible pipe.
As shown in figure 15, when in the present invention, unit tube coupling 102 splices vertically, at the axial seamed edge of adjacent cells tube coupling
The rigid connection structure across adjacent cells tube coupling is provided with, the rigid connection structure includes a pair being fastened on unit tube coupling rib relatively
