1. a kind of bored concrete pile pile body deformation becomes more meticulous measuring method, it is characterised in that comprise the following steps:

  • Step 1, fabrication of reinforcing cage stage, the axially disposed optical fiber on steel reinforcement cage;

    Step 2, the reinforcement cage hoisting decentralization stage folds the remaining optical fiber of protection, after steel reinforcement cage welding, continues to arrange remaining lightIt is fine;

    The optical fiber of pile body is stretched out in step 3, protection before placing concrete;

    Step 4, welding is carried out by the optical fiber for stretching out pile body with wire jumper, and wire jumper access OBR reflexometers are carried out into data acquisition;

    Step 5, to the optical fiber for stretching out pile body is protected with wire jumper after collection.
