  Foundation excavations are deepening, expanding, and approaching structures.
Steel supports measure and manage axial force. The study regulates steel
support structure power during deep excavation using a novel axial force
management system for safety, efficiency, and structural integrity. Closed-loop
control changes actuator output to maintain axial force based on force. In deep
excavation, the servo system regulates unstable soil, side pressure, and
structural demands. Modern engineering and tech are used. Temperature changes
automatically adjust the jack to maintain axial force. Includes hydraulic
jacks, triple-acting cylinders, temperature, and deformation sensors, and
automatic control. Foundation pit excavation is dynamic, yet structure tension
is constant. There is no scientific way to regulate axial force foundation pit
excavation. The revolutionary Servo system adjusts temperature, compression,
and axial force to deform pits. System control requires foundation pit
direction detection and modification. This engineering method has performed
effectively for deep foundation pit excavation at railway crossings and other
infrastructure projects. The surrounding protective structure may reduce the
steel support's axial stress, making deep foundation excavation safe and
efficient. Keywords: Servo systems, Steel strut support design, Deformation
