Work platform substitutes pier construction scaffold, in conjunction with template outrigger, is convenient for assembling reinforcement, and method constructing and overhanging model is turned in cooperation, improves work efficiency,
It is horizontal to improve standardized management.
Construction process is surveying and locating → concrete dabbing → pier shaft internal frame installation → reinforcing bar binding → template installation → interior
Frame hangs out → concrete placings → over-form construction.
Specifically, comprising the following steps:
Step 100, surveying and locating；
Bridge pier direction across bridge center of arc vertex is released on cushion cap face using total station, along bridge to point before and after pier center, straight
Four angle points of line segment amount to 8 points, and pop up pier shaft outer contour and template outer contour；
Step 200, concrete dabbing；
Grooving is carried out to cushion cap face along contour line using cutting machine, then carries out concrete surface dabbing；
Specifically, cushion cap face dabbing, which is used, carries out grooving along contour line using cutting machine, and depth about 2cm carries out coagulation afterwards
Native face dabbing.When artificial chiseling, concrete strength is not less than 2.5MPa；Then it is not less than 10MPa when mechanical dabbing, is carried out after dabbing
Cleaning.At bridge pier merogenesis, to guarantee that seam crossing is smooth, when lower section concreting, pours top surface absolute altitude and went out template top about 0.5-
1cm carries out trimming along template top using angle grinder, and inside uses air compressor machine dabbing or artificial chiseling；
Frame built in step 300, pier shaft is installed；
According to the height of pier shaft 3 and pier neck size, designs the structure snd size of 2 unit 1 of frame built in hollow pier pier shaft and take
Build welding；2 unit 1 of frame built in hollow pier pier shaft is overlapped in 3 upper surface of pier shaft by the supporting rod 110 of two sides of the bottom；
Specifically, it is illustrated by taking hollow slope pier (pier neck is having a size of 8.2*3m) as an example.Hollow pier pier neck is having a size of 8.2*
3m considers that pier neck is having a size of 7.2*2m in 50cm wall thickness.Built-in frame planar dimension is 5.7m × 1.5m, and main framing uses 4 ∠
100mm × 100mm × 6mm angle steel, diagonal brace, lateral part use ∠ 63mm × 63mm × 4mm angle steel；
Frame built in fashioned iron is processed by mono- section of 2m, and direction across bridge arranges 16 plain bar of φ by spacing 30cm at the top of every section,
Vertical bridge completely spreads 35cm wide 3mm embossed steel plates as workbench to small mileage, big mileage and direction across bridge left and right side.In direction across bridge
Side arranges that size is not less than 60cm × 60cm into Ren Dong, and the ladder 109 as made of 22 reinforcement welding of φ, ladder 109 is arranged
Every grade of vertical spacing 40cm, horizontal spacing 50cm；
Epimerite is built-in to set up 1.2m high fence, and fence surrounding is welded on upright fence post using 16 plain bar of φ and does column
Bar, and 20cm high 3mm embossed steel plates skirting board is set；
Two road length 2m are set at the fulcrum of built-in frame bottom, and diameter 76mm, wall thickness 4mm Two bors d's oeuveres seamless steel pipe, steel pipe inside has
M68 screw thread, steel pipe both ends are screwed into long 0.6m respectively, and M68 screw rod forms telescopic sleeve pipe structure with seamless steel pipe.It, will when installation
Both ends screw rod back-outs equal length, and overhanging is partially disposed in and is completed on construction pier shaft 3, and solid with hook reinforcing bar is buried in advance
It is fixed.Due to hollow pier boring part, completion section is being poured, anti-drop net is set using internal model strut, is avoiding pendant object.
Step 400, reinforcing bar binding；
Using frame built in pier shaft as job platform, pier shaft reinforcing bar is bound upwards in turn by 3 bottom of pier shaft；
Step 500, template installation；
Template uses over-form construction；When overmolded, on most upper section template indwelling pier shaft 3, following template is turned to most
On upper section template；Template repeats to construct, and makes inside and outside arc plate full configuration, and inner and outer template is fixed in the form of to pull rod；
Specifically, template uses over-form construction, and six pieces of external mold template point, six pieces of inside molding plate point, template is by 2 meters of standard knot
Design, interior external mold plate design 4 section templates altogether, and template processes 8 meters, and each construction formwork turns over 4/6 meter, when each overmolded, most
On upper section indwelling pier shaft 3, following 3 section template is turned on most upper section template, template repeats to construct, and inside and outside arc plate is full
Match, inner and outer template is fixed in the form of to pull rod；
Interlayer ladder is set in external mold, using ladder is logical above and below size mileage side is staggered between every layer of job platform
Row, ladder are process from vertical Liang Gen 63 × 6mm+ of ∟ Heng Xiang ∟ 50 × 5mm angle steel, and one of spacing 21.6cm of ladder step, top
Using the above round steel of diameter 25mm, it is processed into inverted U, on projecting and upper one layer of angle bar frame.
Step 600, built-in frame are hung out；
After reinforcing bar binding, internal frame is integrally hung out using crane；If pier shaft 3 is excessively high, can merogenesis hang out.
Step 700, concrete placings；
Filling concrete uninterruptedly continuously is carried out to pier shaft 3；
Specifically, the perfusion of Bridge Pier concrete guarantees continuous uninterrupted construction, and perfusion pier concrete freely inclines
Drop height degree is no more than 2m, more than when using sliding slot, tumbling barrel or deceleration cylinder reduce the degree of falling that freely inclines, reduce segregation phenomenon to the greatest extent.
The perfusion of pier concrete wants horizontal slice to carry out, and lift height controls within 30cm, and concrete wants vibration compacting, cannot leak
Vibration, owed to shake or over vibration, vibrating time are controlled in 10~20s or so, start bleeding with surface, bubble no longer occur is advisable.
Step 800, over-form construction；
3 hollow thin-wall section of pier shaft is constructed using overmolded method, on most upper section indwelling pier shaft 3 when each overmolded, general
Lower face die plate turns on most upper section template, and circulation is until 3 hollow section of pier shaft is completed.
Specifically, hollow thin-wall section is constructed using overmolded method, and overmolded height is that 4m, 6m are each, and a most upper section is stayed
It sets on pier shaft 3, following 3 section template is turned on most upper section template, circulation is until 3 hollow section of pier shaft is completed.
