Project Description:

 Aiming at the survey problems of complex geological conditions and sensitive surrounding environment of urban rail transit projects, the project has created the first integrated process applicable to external safety and management of urban rail transit survey, combined with mobile Internet, GIS and IoT technologies, built a set of digital management system for urban rail transit survey, combined with paperless data collection, control of safety process of opening holes, video monitoring, management of indoor tests, collaboration, office and other means to improve the efficiency of survey quality and safety management, and realized the application of informatization of survey management. Office and other means to improve the quality and safety management efficiency of the survey, realizing the application of survey management informationization; relying on independent research and development breakthroughs in the application of the virtual source method in the wells, overcoming the difficulties of the conventional engineering physical prospecting methods restricted by site conditions and the complexity of interference in the shallow surface, and improving the spatial positioning capability of the undesirable geological bodies; using advanced technology to accurately locate and determine the depth of pipelines, creating an upstream and downstream all-process integrated information operation mode, and creating the first "information operation mode", and creating the "information operation mode", and creating the "information operation mode". The company has created an information-based operation mode, the first "panoramic map image" expression of results, realized fully automatic BIM modeling based on geological database, and built a new mode of pipeline exploration results in the whole process. The company has completed the investigation work of more than 90 rail transit lines in more than 20 cities across the country, edited or participated in more than 20 books of geotechnical investigation standards for rail transit, and won more than 30 awards in various categories.

Technical Highlights:

 1. digital management system for the whole process of urban rail transit investigation.

 2. BIM fully automatic 3D geological modeling based on massive geological data.
