It is gradually reduced under, up big and down small structure is consequently formed, thus increased and the contact of 100 structure of pier stud (such as steel box-girder P)
Area increases load-bearing capacity.
Further, as shown in figure 3, the variable cross-section portion 101 includes：First semicircle pipeline section 1011, the first web 1012,
Second semicircle pipeline section 1013 and the second web 1014；The first semicircle pipeline section 1011, the first web 1012, the second semi-circular tube
Section 1013 and the second web 1014 are sequentially connected and (such as weld), to surround the variable cross-section portion 101；And first semicircle
The top of pipeline section 1011 and the second semicircle pipeline section 1013 is bent outwards.Corresponding, the cross-section portion 102 includes：
Third semicircle pipeline section 1021 positioned at the first semicircle pipeline section bottom, the third web positioned at first web bottom
1022, the 4th positioned at the 4th semicircle pipeline section 1023 of the second semicircle pipeline section bottom and positioned at second web bottom
Web 1024.
As shown in figure 4, the first semicircle pipeline section 1011 and the second semicircle pipeline section 1013 include from top to bottom successively
Several straightways of connection, in the present embodiment, the straightway has 4, is L1-L4, and the interconnecting piece 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
It is selected as 10mm).
As shown in Fig. 5 a-5b, the footing 300 includes：Anchoring base 301 and setting are on the anchoring base 301
Support portion 302 (can be cylindrical steel structure).Add specifically, being provided with several outsides around 302 peripheral surface of the support portion
Strength plate 303, and inside stiffener 304 arranged in a crossed manner is arranged in 302 inside of the support portion.Further, it is that enhancing structure is strong
Degree, 301 lower surface of the anchoring base are provided with several anchor ribs 305, it is preferred that the anchor rib 305 can form several
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 comprising following step
Suddenly：
S1, straight-seam pipes are cut in half as two semicircles, obtaining several straightways, (each straightway is a semicircle
Pipe is straightway in each semicircle length of tube), third 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 when blanking and cuts surplus (surplus 8-12mm, preferably 10mm)；Again by several straightways on moulding bed spelling
(such as Fig. 6), docking site give intersection coordinate, and adjust it is linear after progress positioning welding, to form described the first half
Pipe section and the second semicircle pipeline section；When 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, the first semicircle pipeline section, the second semicircle pipeline section completing to weld are carried out non-destructive testing, is closed
It is for use 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
It after the cutting of hand handle cutter, polishes according to the requirement of manufacture rule, reaches the given bevel angle of qualification of welding procedure and root face ruler
It is very little；
S2, cutting form first web, the second web, third web and the 4th web；Likewise, the first web
And second with a hook at the end to repair at the top of web and cut surplus (surplus 8-12mm, preferably 10mm)；Likewise, each web welds slope
Mouth is also the bilateral V-butt of single side, after can using the cutting of hand handle cutter, polishes according to the requirement of manufacture rule, reaches welding procedure
The given bevel angle of evaluation and root face size；
S3, welding the first semicircle pipeline section, the second semicircle pipeline section, the first web and the second web, form the change
Cross-section；
S4, the welding third semicircle pipeline section, the 4th semicircle pipeline section, third web and the 4th web, form described etc.
Cross-section；
S5, variable cross-section section and cross-section section are crouched on platform and spelled, carry out tunneling boring docking, the variable cross-section section after spelling with
Cross-section section should check that each portion's size, especially intermediate diagonal line are poor；Positioning welding is carried out after each dimensional gaughing qualification；Welding is made
CO is used when 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 is carried out non-destructive testing；
S6, cutting form the external 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 support portion；
When external stiffener welding, bisector and external stiffener bars position line first are marked in support portion peripheral surface,
Then external stiffener spelling and positioning welding are carried out, thus will the external stiffener be welded to the support portion peripheral surface with
And on anchoring base；
And the external stiffener positioning welding it is complete after, check bottom plane, such as external stiffener is not same flat
In face, then external stiffener must be reinstalled, external stiffener out of plumb must then polish or mechanical process；
S7, the anchor rib is fixed in the anchoring base lower surface, 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 carry out arbitrary combination, and the skill being composed
Art scheme belongs to the scope of protection of the utility model.
In conclusion the bicycle occupation bridge pillarwork and its construction method of the utility model can segmentation groups at the scene
Dress, welding, convenience in transport, construction efficiency are high；And multi-point welding technique is used, structure is slim and graceful, solid reliable.
