AI Technical Summary

Technical Problem

In existing technologies, during underwater blasting and compaction, sensors are easily damaged and pipelines are easily broken, making it impossible to accurately monitor the stratified settlement of the boulders foundation. Furthermore, the measuring points cannot form an integral settlement with the foundation, resulting in data distortion.

Method used

Rigid bearing steel plates and sealed protective covers are used to protect the differential pressure static level. Combined with flexible protective pipes and buffer filling layers, a coordinated deformation integral settlement body is formed. The external benchmark position is not affected by blasting vibration. The absolute elevation is obtained through high-precision measurement. Combined with a data acquisition system, layered settlement monitoring is realized.

Benefits of technology

It effectively protects the sensors, ensures data accuracy and continuity, provides high-precision monitoring of layered settlement, and supports the optimization of blasting and compaction construction parameters and quality control.
