AI Technical Summary

Technical Problem

Traditional inclinometer tubes are prone to tilting and damage during the lowering process, resulting in high labor intensity and low construction efficiency.

Method used

The inclinometer tube is lowered stably by using a bottom pulley device and a drive motor system, and by combining a wire rope coil and pulleys, ensuring that the inclinometer tube remains vertical during the lowering process.

Benefits of technology

This improves the stability of the inclinometer tube during lowering, avoids damage, saves manpower, reduces construction costs, and increases construction efficiency.
