It is illustrated by taking the pier of entity slope as an example.Entity slope pier pier neck is having a size of 7.8m*1.8m, built-in frame planar dimension
5.7m × 1.5m, main framing use 4 ∠ 100mm × 100mm × 6mm angle steel, diagonal brace, lateral part using ∠ 63mm ×
The angle steel of 63mm × 4mm;Frame built in fashioned iron is processed by mono- section of 2m, and direction across bridge arranges 16 light of φ by spacing 30cm at the top of every section
Round bar, vertical bridge completely spread 35cm wide 3mm embossed steel plates as workbench to small mileage, big mileage and direction across bridge left and right side;?
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 is arranged, and climbs
109 every grade of vertical spacing 40cm, horizontal spacing 50cm of ladder;
Step 400, reinforcing bar binding;
Using frame built in pier shaft as job platform, pier shaft reinforcing bar is bound upwards in turn by pier shaft bottom;
Step 500, template installation;
Template uses over-form construction;When overmolded, on most upper section template indwelling pier shaft, following template is turned to most upper
It saves on 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;
Pier is template used and bracket must have enough rigidity, strength and stability, can bear newly-laid concrete enough
Gravity, lateral pressure and load.On the basis of falsework is supported in reliably, and there are enough bearing area and drainage measure;
Interlayer ladder is set on the outside of template, 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;
It binds with template after the installation is completed in reinforcing bar, is integrally hung out built-in frame using crane;If pier shaft 3 is excessively high, can divide
Section is hung out;
Step 700, concrete placings;
Filling concrete uninterruptedly continuously is carried out to pier shaft, completes the construction of solid pier shaft.
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 concrete slump controls within 70~100mm, and lift height control exists
Within 30cm, poker vibrator vibrates.
It should be noted that being installed in above-mentioned work progress in frame built in application pier shaft to carry out reinforcing bar binding and template
When, step 300 to step 700 repeats, and frame 2 built in solid pier pier shaft is placed on pier first, with solid Dun Dun
Frame 2 built in body is the reinforcing bar binding and template installation that workbench carries out a section pier shaft, hangs out frame built in pier shaft later, completing should
Save the construction of pier shaft;It is placed on the pier shaft of completion, carries out after the completion of the section pier shaft is built, then by frame 2 built in solid pier pier shaft
The reinforcing bar binding and template installation of next section pier shaft;It repeats the above process, until solid pier pier shaft integral constructing is completed.
Construction method provided by the embodiments of the present application has following features:
1. placing shelf structure is simple in, and main framing uses angle steel welding fabrication, and ladder 109 is welded using round steel up and down for side,
Top surface spreads embossed steel plates as job platform, single-unit length 2m, though volume is small, has the function of independent use;
2. setting up simple, work efficiency height using frame construction built in pier shaft.Built-in frame single-unit length is 2m, light-weight;In every section
It sets frame and is bolted fixation using M22 × 60, it is easy for installation, the time is saved, work efficiency improves significant;
3. using frame construction save the cost built in pier shaft;The engineering method, installation few using steel compared to conventional steel scaffold
It is required it is artificial less, the set-up time it is short, cost savings.
4. complying with standard manages;Built-in frame is used uniformly angle steel production, and standard knot is used uniformly mono- section of 2m, completely uses
Unified standard is constructed, and unified coordination and administration are convenient for.
Finally it should be noted that:The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations;To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, those skilled in the art should understand that:Its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement;And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
