Abstract
The utility model discloses a kind of power tunnel telescoping steel form locking plug template installation ruggedized constructions to be arranged circumferentially more piece channel steel along the radian of telescoping steel form on the outside of locking plug template, often saves channel steel and is fixed on telescoping steel form panel by rod iron；Long timber wedge is equipped between the channel steel and the locking plug template；The rod iron includes at least the first rod iron and the second rod iron, and first rod iron encircles the channel steel and telescoping steel form panel welding from side, and second rod iron is welded in the channel steel back side across the telescoping steel form panel.By the utility model, two lined steel mould trolley plug formwork erections are quick, simple, firm, operate, accelerate construction progress convenient for operating personnel, reduce operating personnel, reduce risk, shorten the construction period, and installation and strengthening quality are significantly improved.
Description
Technical field
The utility model is related to power tunnel telescoping steel form technical field of construction, specifically a kind of power tunnel telescoping steel form plug
Template installs ruggedized construction.
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, need not block, in addition face empty side, then needs that locking plug template is arranged.Due to the thickness of Tunnel Second Lining
It changes 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 are deposited as trolley end plug since reinforcement technique is not in place
In following problem.
1. the construction time is long：Since tunnel cross-section changes, supporting steel pipe cannot follow skewed horizontal load scaffolding steel pipe with template
Ring utilizes, and concrete vibrating is affected to locking plug template and support tube, causes spillage at form joint, and race mould occur, lead
The position offsets such as waterstop, built-in fitting are caused, need repeatedly to be handled, the construction time is long.
2. circulation material waste is big：Tunnel excavation section is influenced by various factors, often recycles two thickness of the liner degree of each section
It is uneven, need the plank of various different lengths；The locking plug template damage of dismounting is more, needs a large amount of planks to be had enough to meet the need, week
It is low to turn stock utilization, construction cost increases.
3. security risk is big：Locking plug template is reinforced, and mould is seen in concreting process, and often cycle needs several templates
Work, average each form fixer expend 3-6h, need personnel more, stream time is long, and security risk is big.
Utility model content
In view of the above-mentioned problems, the utility model 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 installation ruggedized construction, on the outside of locking plug template, along the arc of telescoping steel form
Degree is arranged circumferentially more piece channel steel, often saves channel steel and is fixed on telescoping steel form panel by rod iron.
Preferably, the long 1-2m of channel steel is often saved.
Preferably, long timber wedge is equipped between the channel steel and the locking plug template.
Preferably, the rod iron includes at least the first rod iron and the second rod iron, and first rod iron is encircled described from side
Channel steel and telescoping steel form panel welding, second rod iron are welded in the channel steel back of the body across the telescoping steel form panel
Face；The rod iron further includes third rod iron, and the third 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 25 screw-thread steels of φ, second rod iron and the third rod iron to use φ 12
Round steel.
The beneficial effects of the utility model：1. two lined steel mould trolley plug formwork erections are quick, simple, firm, it is convenient for operation people
Member's operation, accelerates construction progress, and reduces operating personnel, reduces risk, shortens the construction period；2. compared with reinforcement means before, improve
Circulation material utilization rate reduces project cost；3. two lined steel mould trolley locking plug templates are installed and strengthening quality is significantly improved.

On 10, the long 1-2m of channel steel is often saved.
Long timber wedge 50, by long timber wedge wedging, the long long 15- of timber wedge are equipped between the channel steel 30 and the locking plug template 20
25cm。
The rod iron includes at least the first rod iron 401 and the second rod iron 402, and first rod iron 401 encircles institute from side
Channel steel 30 and the telescoping steel form panel 10 welding are stated, second rod iron 402 is welded in across the telescoping steel form panel 10
30 back side of the channel steel；The rod iron further includes third rod iron 403, and the third rod iron 403 and second rod iron 402 are side by side
Welding, one end is fixed on the telescoping steel form panel 10；First rod iron use 25 screw-thread steels of φ, second rod iron and
The third rod iron uses 12 round steel of φ.Fixed structure in this way, channel steel are relatively fixed to telescoping steel form panel securely
