Description
Technical field
The present invention relates to power tunnel telescoping steel form technical field of construction, specifically a kind of power tunnel telescoping steel form locking plug template
Ruggedized construction is installed.
Background technology
Power tunnel barrel engineering in two lining concrete placements, with shaped mix by the side at telescoping steel form both ends
Solidifying soil contact, it is not necessary to block, face the side of sky in addition, then need to set locking plug template.Due to the thickness of Tunnel Second Lining
Changed with Grades of Surrounding Rock, and country rock basal plane caused by drilling and blasting method excavation is uneven, locking plug template can not make sizing
Punching block.
In the prior art, generally use plank and steel pipe combination, because reinforcement technique is not in place, are deposited as chassis end plug
In following problem.
1. the engineering time is grown：Because tunnel cross-section changes, supporting steel pipe can not follow skewed horizontal load scaffolding steel pipe with template
Ring utilizes, and concrete vibrating has a great influence to locking plug template and support tube, causes spillage at form joint, and race mould occurs, leads
The skew of the positions such as waterstop, built-in fitting is caused, it is necessary to repeatedly be handled, engineering time length.
2. circulation material wastes big：Tunnel excavation section is influenceed by various factors, often circulates two thickness of the liner degree of each section
It is uneven, it is necessary to the plank of various different lengths；The locking plug template damage of dismounting is more, it is necessary to a large amount of planks are had enough to meet the need, week
It is low to turn stock utilization, construction cost increase.
3. security risk is big：Locking plug template is reinforced, and mould is seen in concreting process, and often circulation needs several templates
Work, average each form fixer expends 3-6h, it is necessary to which personnel are more, and stream time is grown, and security risk is big.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of power tunnel telescoping steel form locking plug template installation ruggedized construction.
A kind of power tunnel telescoping steel form locking plug template installs ruggedized construction, on the outside of locking plug template, along the arc of telescoping steel form
Degree is arranged circumferentially more piece channel-section steel, often saves channel-section steel and is fixed on by rod iron on telescoping steel form panel.
Preferably, the long 1-2m of channel-section steel is often saved.
Preferably, long timber wedge is provided between the channel-section steel and the locking plug template.
Preferably, the rod iron comprises at least the first rod iron and the second rod iron, and first rod iron is encircled described from side
Channel-section steel and telescoping steel form panel welding, second rod iron are welded in the channel-section steel back of the body through the telescoping steel form panel
Face；The rod iron also includes the 3rd rod iron, and the 3rd rod iron welds side by side with second rod iron, and the steel is fixed in one end
On mould trolley panel.
Preferably, first rod iron uses the screw-thread steels of φ 25, and second rod iron and the 3rd rod iron use φ 12
Round steel.
Beneficial effects of the present invention：1. two lined steel mould trolley plug formwork erections are quick, simple, firm, it is easy to operating personnel to grasp
Make, accelerating construction progress, reduce operating personnel, reduce risk, shorten the duration；2. compared with reinforcement means before, turnover is improved
Materials'use rate, reduce project cost；3. two lined steel mould trolley locking plug templates are installed and strengthening quality is significantly improved.
