Foundation Pit Monitoring

Foundation pit monitoring refers to the systematic, real-time measurement, observation, and analysis of the state changes of the pit itself, the surrounding environment (such as adjacent buildings, roads, pipelines, etc.), and the supporting structures during the excavation of building foundation pits and the construction of underground structures. It uses professional instruments, equipment, and technical methods. This information-based approach ensures the safety of the pit and its surroundings. The company holds a Class A qualification in Engineering Surveying (specifically Geotechnical Engineering – Geophysical Testing, Inspection, and Monitoring), meaning there is no scale limit to the foundation pit monitoring projects we can undertake.

Testing Products

Deformation Monitoring

Internal Force Monitoring

Environmental Monitoring

System Platform

Testing Items

Support Structure Monitoring:

Horizontal and vertical displacement of the support structure top; deep (lateral) horizontal displacement; internal forces (e.g., strut axial force, anchor tension); settlement, etc.

Surrounding Environment Monitoring:

Settlement of the surrounding ground, roads, and pipelines; settlement and tilt of adjacent buildings; cracks, etc.

Other Key Items:

Groundwater level; uplift (heave) of the pit bottom; layered settlement of soil, etc.

On-site Inspection (Walkthrough):

Equally important as instrument monitoring. Includes checking for anomalies like cracks, leaks, bulging, etc., in the supporting structure, construction conditions, and the surrounding environment.
