AI Technical Summary

Technical Problem

In existing technologies, the steel cage cannot be accurately positioned during pile foundation construction, especially when using mud slurry for wall protection, making it difficult to check for deviations, which makes it difficult to guarantee the bearing capacity and construction quality of the pile foundation.

Method used

A new type of pile foundation reinforcement cage center positioning inspection device is adopted. By setting supports, laser emitters, PSD sensors and linear charge coupling devices on the pile foundation and reinforcement cage respectively, the device can accurately detect the center of the reinforcement cage and the center of the pile foundation and measure the offset in real time. The device provides intuitive feedback using a display and sensor lights.

Benefits of technology

This technology enables real-time center positioning detection and precise measurement of offset during the lowering process of the reinforcing cage, improving the installation accuracy of the reinforcing cage and the construction quality of the pile foundation, and ensuring the bearing capacity and service life of the pile foundation.
