Big advantage is exactly not need Large-scale Hoisting equipment.For the project that the duration is shorter, when installation, the dismounting of support take critical circuits
Between it is longer, be unfavorable for the control of total lever factor.
Girder rotator construction is used for the project of the special construction condition such as cross-domain deep valley, existing railway, highway, in having not
Break off a friendship the characteristics of logical, but this method can only spatially solve the problem that can not be constructed, but for duration urgent project, do not have
There is obvious advantage, be equally unfavorable for project duration control.
Above construction method has an advantage of its own for different geology and geomorphologies, meteorology, hydrologic condition, but for
Duration shorter project, above method can not solve problem in a manner of single, conventional method need to be optimized.
