Automatic determination method for key procedure of diaphragm wall trd three-step construction
The intelligent monitoring device, which uses GNSS dual antennas and differential pressure density meters, automatically identifies key construction procedures of the TRD three-step method for cutoff wall construction. This solves the problems of lag and error in manual judgment in existing technologies, and realizes real-time monitoring and quality control of cutoff wall construction.

Abstract
This invention relates to an automatic determination method for key construction processes in the three-step TRD (Transmission Removal and Damping) method for cut-off walls, comprising: S1, data acquisition; S2, data processing; S3, switching logic for key construction processes; and S4, delay correction for process transition points based on continuous time. This invention provides effective real-time monitoring and automatic determination technology, enabling integrated monitoring of the entire TRD construction process from "cutting to mixing to wall formation," significantly improving the transparency and controllability of the construction process, and providing an effective means for quality control in cut-off wall construction.
