Description

Major diameter drilling bored concrete pile steel reinforcement cage positioner

Technical Field

The utility model relates to a bored concrete pile steel reinforcement cage hoist and mount technical field especially relates to a major diameter bored concrete pile steel reinforcement cage positioner.

Background

With the large-scale construction of highway and railway express road networks in China, a large number of cross-river, river and sea bridge girders are built in succession, and the huge bridges are usually required to build huge pier foundations in deep water. The construction of large-diameter and ultra-long piles of a bridge in a deep water environment inevitably meets the problem that an overweight reinforcement cage is difficult to accurately position a lifting hole opening after being placed. After the last section of reinforcement cage is put down in place, the traditional orifice positioning method is to find out the center of the reinforcement cage, adjust the lifting hook of the crane to make the center of the reinforcement cage coincide with the center of the protective cylinder, and then fix the lifting rib. And the last section of reinforcement cage needs to be lengthened when being put down, after the reinforcement cage is put down in place, the whole reinforcement cage is completely submerged in the slurry, only a few lengthened hanging ribs are exposed outside the opening of the protective sleeve, therefore, after the reinforcement cage is put down in place, the center of the reinforcement cage needs to be found, the center position of the reinforcement cage can be deduced only through the lengthened hanging ribs (generally 4), the diagonal hanging ribs are connected through stay wires in the conventional method, and the center position of the reinforcement cage is determined through the intersection point of the connecting wires.
