Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in further detail.A kind of bridge superstructure
The pump line fixing meanss that concrete pumping pours, comprise the steps：
（1）According to technological requirement, in bridge pier column 1 assembling reinforcement and formwork early stage, by certain spacing, install along short transverse
Built-in fitting 4, after pier stud 1 concreting molding, form removal, is equipped with each built-in fitting 4（Install）Fixation clamp 8, leads to
Cross the pump line 5 that fixation clamp 8 fixing concrete pumping pours, form the vertical section being vertically arranged along bridge pier column 1；
（2）According to technological requirement, pour bridge pier column 1 top bridge superstructure steel structure 2 when, first pour bridge top knot
The central segment of structure steel structure 2（Region shown in figure label）Afterwards, the vertical section of pump line 5 first extends upwardly beyond the height of central segment,
Centrally disposed section surface；Pump line 5 turns again to horizontal-extending, extends to the left or to the right, and cushion block 6 is installed to discharging in pump line 5 bottom
Mouth 7, forms horizontal segment；
（3）According to technological requirement, in central segment both sides, symmetrically pour the second segment of bridge pier column 1 superstructure steel structure 2（In figure
Region shown in label）；After second segment pours, in the side of this two sections of second segments, symmetrically pour the 3rd section（In figure label
Shown region）；...., until forming continuous steel frame system on bridge pier column 1 top, form the bridge top meeting technological requirement
Structural steel structure 2.When pouring second segment, other more multistages after the 3rd section, or the 3rd section, accordingly extend pump line in the horizontal direction
5 horizontal segment, corresponding every section of length, corresponding suitable unloading position is so as to the casting position of corresponding every section of discharging opening 7, full
Foot pours needs.Steel structure construction hanging basket 3 is the appurtenances that construction needs.
In order to adapt to the needs of Specific construction, the vertical section of described pump line 5 is two, independently arranges, be respectively adopted
One group of built-in fitting 4 is installed with fixation clamp 8；So, every pump line 5 forms horizontal segment to the left or to the right respectively, more conducively symmetrically
Pour bridge pier column 1 top the second segment of firm structure, the 3rd section.
After the continuous steel frame System forming on bridge pier column 1 top, when needing to remove, first remove pump line 5 horizontal segment, then tear open
Except the fixation clamp 8 on pier stud, specifically adopt the fixation clamp 8 on artificial cutting torch protective demolition pier stud, repeat using dismounting
Fixation clamp 8 is assembled on the built-in fitting 4 of next pier stud, and in the vertical section removing pump line 5, the pump line 5 that can be used in turn just can continue
Continuous use.
The fixing corresponding improvement of pump line 5：Fixation clamp 8 and pump line 5 are to encircle design, and fixation clamp 8 is enclosed in around pump line 5,

And install convenient, fixation clamp 8 designed and produced using open laterally close fixing pump line 5；On fixation clamp 8, setting is lived
Dynamic fixture block, movable clip block is provided with moveable hinge contact 9 and dead bolt bore 10, and movable clip block passes through the hinge of moveable hinge contact 9
The latch of fitting and dead bolt bore 10 is connected on the miscellaneous part of fixation clamp 8（On adjacent fixture block）, can achieve and install
It is firm that the attachment of the fixation clamp 8 on position and pump line 5 consolidates, and pump line 5 connect overall due to solid by certain spacing attachment
It is scheduled on bridge pier surface, forms its concrete pumping and pour bridge upper steel structure, stringing system is fixed in stable, complete high-altitude.
The fixing construction technology of pump line being poured using the bridge superstructure concrete pumping after improving and method, can shorten bridge
The activity time that the pumping of superstructure concrete pours, it is ensured that bridge superstructure concrete pumps the quick formation pouring, improves concrete pumping
The working security pouring, realizes the pumping of bridge superstructure concrete and pours closely knit quality technology effect.Its technological process is as follows：
（1）Erection sequence：1. bridge pier column 1 is wire-tiing and formwork early stage, installs the pier stud of built-in fitting 4 → 2. by certain spacing
1 concreting molding, form removal → 3. are in each built-in fitting position over-assemble pump line fixation clamp 8 → 4. in fixation clamp 8 over-assemble
Fixing pump line 5 → 5. pour bridge upper steel structure 1. → 6. the horizontal-extending cloth pipeline section cushioning block 6 of pump line 5 is to unloading position 7 → 7.
Symmetrically pour bridge upper steel structure 2. → 8. symmetrically pour steel structure 3. →.Symmetrical casting concrete is until form bridge superstructure
1. -2. -3. ... .. continuous steel frame system
（2）Dismounting order：1. the steel of bridge superstructure be configured to concrete strength confirm reach → 2. remove pump line 5 horizontal segment
→ be 3. assembled on the built-in fitting 4 of next pier stud using the fixation clamp 8 of the fixation clamp 8 on artificial cutting torch protective demolition pier stud → 4.
→ 5. the pump line being used in turn is arranged on fixation clamp 8 and is continuing with.
The fixing construction technology of pump line of the present invention and method, when can shorten the pumping of bridge superstructure concrete and pouring operation
Between it is ensured that the quick formation that pours of pumping of bridge superstructure concrete, improve the working security that concrete pumping pours, realize on bridge
Portion's Concrete In Structures pumping pours closely knit quality technology effect.
Above example only in order to technical scheme to be described and unrestricted, although with reference to preferred embodiment to this
Bright be described in detail, it will be understood by those within the art that, technical scheme can be modified
Or equivalent, the objective without deviating from technical solution of the present invention and scope, it all should cover the claim in the present invention
In the middle of scope.
