AI Technical Summary

Technical Problem

Existing anchor bolt positioners can only be used with anchor bolts of specific specifications and cannot be adapted to anchor bolts of different diameters, resulting in high project costs, long construction periods, and quality fluctuations.

Method used

A positioning device for anchor bolts in deep foundation pit slope protection was designed. By setting multiple annularly distributed fixing blocks and threaded positioning rings on an external threaded pipe, the fixing blocks are bent by the squeezing action of the positioning rings to clamp anchor bolts of different diameters, thus achieving multi-specification adaptability.

Benefits of technology

It improves the versatility of anchor bolt positioning devices, reduces project costs, shortens construction cycles, and enhances construction efficiency and quality stability.
