Existing blower foundation is repaired, and cost is the highest, thus major part wind field can be selected existing
The scheme in blower foundation, the finish rolling deformed bar buried underground all changed.But nowadays,
To buried underground in blower foundation finish rolling deformed bar be replaced time, be available for use for reference construction information very
Lack, and the installation method of neither one unification, standard and specification is available for following, during practice of construction not
The problems such as operation is random, efficiency of construction is low, time-consuming, using effect is poor can be there is with avoiding.
It addition, to buried underground in blower foundation finish rolling deformed bar be replaced time, need first will bury underground
Finish rolling deformed bar extract out in blower foundation.Finish rolling deformed bar was extracted out in blower foundation
Cheng Zhong, when finish rolling deformed bar ejects after being likely to occur fracture, and finish rolling deformed bar fracture easily
Hurt workmen.Thus, need finish rolling deformed bar is carried out reinforcement protection before construction, it is to avoid eject
After hurt sb.'s feelings.
