Description
Technical field
The present invention relates to construction engineering technical fields, and in particular to a kind of turnover mechanism suitable for assembled under-traverse tunnel
And method for turning.
Background technique
In construction engineering technical field, city tunnel construction, tunnel component usually has cast-in-place and prefabricated mode,
For cast-in-place mode, due to needing longer curing period, it is unfavorable for shortening the construction period, so at present for turning under formula
For tunneling road, prefabricated form of construction work is usually used.
When for carrying out tunnel component prefabricated construction using prefabrication system, although can substantially shorten the construction period,
In further detail design, inventor has found that current tunnel component prefabricated construction still there is also deficiency, specifically exists
In:
Since to be related to the usual volume and weight of component all larger in tunnel, switching process is difficult, so how many prefabrication system big absolutely
All be in such a way that working morphology is prefabricated, it is prefabricated and inconvenient under working morphology but for certain components, such as
For M Vierendeel girder and W Vierendeel girder, after the completion of pouring mold according to the manufacture of W Vierendeel girder, when progress M frame is beam prefabricated, it is difficult to
It is overturn to mold is poured, so needing to carry out prefabricated components 180 ° of overturning, due to M frame after the completion of element precast
The big weight weight of beam body product is usually to be overturn using the traditional approach in Large-scale Hoisting equipment cooperation sand pit at present, the overturning side
Method work efficiency is lower, meanwhile, prefabricated components are easy to damage in switching process, and there are biggish construction risks in switching process.
It is overturn so needing to design one kind at present and can either be suitable for tunnel component, and can be improved overturning efficiency, and
Reduce the turnover device of construction risk.
Summary of the invention
