Experimental Study on Automatic Control Technology in Prestressed Concrete Structure

Prestressed concrete is wildly used on slope retaining(anchor bar or anchor rope), bridge, architectonics engineering and so on. Combined automatic control technology with tensioning device, the prestress was tensioned directly by data change between tensioning robot and programmable automatic controller in system, the automatized process of construction could be practiced. It is shown that the dual control of prestress tensioning can attain to high accuracy and efficiency by the prestressed robot, and fulfill the demand of practical application in prestressed concrete structures and has wide engineering background and good applying prospect.
