Abstract
This invention belongs to the field of prestressed construction technology, and specifically relates to a cable threading method. The traction construction of the steel strand is divided into two stages according to the size of the remaining space inside the outer tube, and cable threading plates or cable threading blocks are selected accordingly for construction. This enables the safe and reliable traction operation of the steel strand under the condition of compact cable threading space, and solves the construction problem of reducing the size of the outer tube cable.
