    Abstract：The paper explores to establish the independent signal grounding system in limited space by setting up grounding deep wells and flexible grounding electrodes and practicing non-excavation operations. The safety problems due to two sets of grounding systems in the buildings are solved by such measures as insulated encapsulation，SPD suppression on voltage difference，and SPMS monitoring system，and the usage specifications and management requirements of the independent signal grounding system are defined.
