During the construction of a subway station excavation, to ensure the safety of the subway structure and operation during construction, the DiCe Tech project team conducted settlement monitoring of the station and the two - end intervals. The monitoring content included settlement monitoring of the station structure, geometric dimension monitoring of the track slab, automated monitoring of elevated bridge piers, and settlement monitoring of the station structure. To detect potential safety hazards and issue early warnings in a timely manner, the field project team stayed on duty, monitoring various data to prevent the occurrence of safety accidents.

As an urban arterial road, the road along the line has rivers, villages, and parks. The planning department plans to build two new bridges and lay four types of underground pipelines for rainwater, sewage, reclaimed water, and water supply in this section. To this end, the DiCe Tech project team developed a targeted solution and used DPP - 100 type vehicle drills, XY - 100 type floor drills, and SH - 30 type drilling rigs for drilling exploration. They promptly compiled investigation result reports on strata and bearing capacity, providing geological data and design parameters for the design and construction of roads, bridges, and underground pipelines.

Using advanced technological means to conduct long - term real - time monitoring of building excavation engineering, various precision sensors and monitoring equipment are used to monitor the changes in various aspects of the construction process on the construction site. Timely and accurate information on construction quality, safety, and efficiency is provided to offer decision - making support and optimization suggestions for the command and management of the construction site. The DiCe Tech Beijing Division project team stayed on the construction site to organize and implement monitoring. The monitoring content included horizontal displacement of pile tops and slope tops, vertical settlement of pile tops and slope tops, deep - level horizontal displacement of supporting structures, settlement of surrounding ground surfaces, settlement of surrounding pipelines, axial force of prestressed anchor cables, groundwater level monitoring, manual inspection, and settlement of surrounding buildings until the monitoring work was completed.

Based on InSAR technology, high - precision geological disaster monitoring and early warning are carried out to detect and deal with risks and hidden dangers in key areas and critical fields in a timely manner, eliminating them before they become disasters and ensuring the safety of people's lives and property as well as social stability. This has great practical significance. Research is conducted on large - gradient settlement monitoring, robust solution of pathological models, and fine - tuning of data processing. A series of key technical difficulties, such as the construction of a 3D deformation joint model, phase unwrapping jumps in steep terrain, and optimal algorithm design, have been broken through. A systematic high - precision geological disaster monitoring method and efficient algorithm for large - gradient areas have been formed, providing technical support for geological disaster monitoring and early warning in complex areas.

To fully understand the utilization type, area, ownership, boundary, and property rights of every piece of land, as well as the condition of houses and their ancillary facilities, to meet the needs of land macro - control, unified registration of immovable property, compilation of land use planning, implementation of strict land management measures, and social service of land and resources information.

Using professional equipment such as UAVs, GNSS systems, total stations, and color digital cameras, and adopting advanced technical methods such as UAV - mounted high - precision 5 - lens oblique cameras for cadastral mapping and partial measurement of house side lengths, cadastral surveys and related measurements of land objects and terrain elements are carried out for each plot. The results of the integrated real - estate - rights investigation are formed to establish a standard, scientific, standardized, and up - to - date rural immovable property rights investigation database, build an integrated urban - rural immovable property registration information platform, and ultimately achieve scientific and modern management of immovable property resources, further enhancing the role of immovable property resources in land and resources management.

An airborne SAR radar RF signal disguise identification device has been invented, which is conducive to safety protection. Meanwhile, the positioning structure on the surface can adjust the installation position, facilitating alignment and avoiding misalignment interference, making installation positioning convenient. The road and surface monitoring points are included to form closed loop networks, compound networks, or compound lines. Monitoring of surrounding surface settlement is carried out to provide timely and reliable information for the construction unit and to provide timely and accurate forecasts of potential environmental safety hazards or accidents, so that effective measures can be taken in a timely manner to prevent accidents.

Within the designated area, the boundaries, shapes, land categories, natural conditions, ownership status, locations, quantities, qualities, and utilization status of each plot of land, house, and real estate are measured. The area is calculated, and cadastral maps are drawn to provide a basis for land registration. Satellite remote sensing data is used to draw boundary lines indoors, create vector data, and establish a rights - confirmation database in combination with historical records.
