Web 1024.
As shown in figure 4, the first semicircle pipeline section 1011 and the second semicircle pipeline section 1013 are included from top to bottom successively
Some straightways of connection, in the present embodiment, the straightway has 4, is L1-L4, and the connecting portion of each straightway gives phase
Transversal, and each straightway, the first web 1012 and the second web 1014 with a hook at the end repair cut surplus (surplus 8-12mm, it is excellent
Elect 10mm as).
As shown in Fig. 5 a-5b, the footing 300 includes：Anchoring base 301 and it is arranged on the anchoring base 301
Supporting part 302 (can be cylindrical steel structure).Add specifically, being provided with some outsides around 302 outer circumferential surface of supporting part
Strength plate 303, and the inside of the supporting part 302 sets inside stiffener 304 arranged in a crossed manner.Further, it is strong for enhancing structure
Degree, 301 lower surface of anchoring base are provided with some anchor ribs 305, it is preferred that the anchor rib 305 can form some
Concentric structure, so that uniform force.
Embodiment two：
The present embodiment additionally provides a kind of construction method of above-mentioned bicycle occupation bridge pillarwork, it includes step as follows
Suddenly：
Straight-seam pipes, be cut in half as two semicircles by S1, and obtaining some straightways, (each straightway is a semicircle
Pipe, is straightway in each semicircle length of tube), the 3rd semicircle pipeline section and the 4th semicircle pipeline section, semicircle after incision can be by
The effect of material internal stress in coiling process and flick, cause half circular diameter after cutting to become larger or lose circle, it is therefore necessary into
Row flame straightening is handled, by the control of tube coupling out-of-roundness in the regular claimed range of manufacture；First semicircle pipeline section, the second semicircle pipeline section
With a hook at the end to ask to repair during blanking and cut surplus (surplus 8-12mm, is preferably 10mm)；Again by some straightways on moulding bed spelling
(such as Fig. 6), docking site give intersection coordinate, and adjusting it is linear after carry out positioning welding, to form described the first half
Pipe section and the second semicircle pipeline section；During welding, using CO2Gas shielded welding is completed, the first semicircle pipeline section after welding, the
Two semicircle pipeline sections must carry out linear repetition measurement, and must be polished on the outside of butt weld, to ensure impression quality, if repetition measurement is unqualified
Then carry out flame straightening processing；Finally, Non-Destructive Testing is carried out to the first semicircle pipeline section, the second semicircle pipeline section completing to weld, closed
It is stand-by after lattice；In addition, the first semicircle pipeline section and the second semicircle pipeline section welding groove are the bilateral V-butt of single side, can use
After the cutting of hand handle cutter, polish according to the requirement of manufacture rule, reach bevel angle and root face ruler that qualification of welding procedure gives
It is very little；
S2, cutting form first web, the second web, the 3rd web and the 4th web；Likewise, the first web
And second with a hook at the end at the top of web to repair and cut surplus (surplus 8-12mm, is preferably 10mm)；Likewise, each web welding slope
Mouth is also the bilateral V-butt of single side, after can using the cutting of hand handle cutter, according to the requirement polishing of manufacture rule, reaches welding procedure
Evaluation given bevel angle and root face size；
S3, welding the first semicircle pipeline section, the second semicircle pipeline section, the first web and second web, form the change
Cross-section；
S4, welding the 3rd semicircle pipeline section, the 4th semicircle pipeline section, the 3rd web and the 4th web, form described etc.
Cross-section；
S5, crouch on platform by variable cross-section section and cross-section section and spell, and carries out tunneling boring docking, the variable cross-section section after spelling with
Cross-section section should check each portion's size, and especially middle diagonal is poor；Positioning welding is carried out after each dimensional gaughing qualification；Welding is made
CO is used during industry2Gas shielded arc welding carries out variable cross-section section and the intersegmental welding of cross-section；Each portion's size is checked after welding, to deformation
Position is corrected, and carries out Non-Destructive Testing；
S6, cutting form the exterior stiffener and internal stiffener；The internal stiffener blanking gives tolerance -6
~-4mm (as shown in Figure 7), and internal stiffener is first welded as entirety, it is being welded to inside the supporting part；
During exterior stiffener welding, bisector and exterior stiffener bars position line first are marked in supporting part outer circumferential surface,
Then exterior stiffener spelling and positioning welding are carried out, thus will the exterior stiffener be welded to the supporting part outer circumferential surface with
And on anchoring base；
And the exterior stiffener positioning welding it is complete after, check base plane, such as exterior stiffener is not same flat
In face, then exterior stiffener must be reinstalled, exterior stiffener out of plumb must then polish or mechanical process；
S7, in the anchoring base lower surface fix the anchor rib, forms the footing；
And S8, top and lower part that the pier stud, footing are correspondingly arranged to the cushion cap respectively.
It should be noted that the technical characteristic in above-described embodiment one, two can be combined, and the skill being composed
Art scheme belongs to protection scope of the present invention.
In conclusion the present invention bicycle occupation bridge pillarwork and its construction method can at the scene sectional,
Welding, convenience in transport, construction efficiency are high；And multi-point welding technique is used, structure is slim and graceful, solid reliable.
