1.Metro Monitoring Monitoring Background
Metro Monitoring is used to monitor the environment of subway projects and the possible deformation of surface and underground structures during construction.Like the oxygen supplier of modern cities, the subway provides power and energy to the continuous development of the city.It not only creates wealth and business opportunities, but also leads the changes in the living style and creates a subway city era.In recent years, subway accidents have continued to occur, and the total number of casualties has begun to increase significantly, and the curve has shown a significant upward trend.The accident reflects the shortcomings of safety construction monitoring technology and means, as well as the lack of construction safety management and supervision efforts.The high technical content and high risk in subway construction all require strong safety awareness, careful safety management and strict safety supervision to achieve.Subway projects are largely a project that tests safety management.In order to keep an eye on the construction status of the subway at any time, provide early warnings for emergencies, maintain the safety and social stability of subway construction, so that tragedies like the landslide in Hangzhou will not happen again, and safety of subway construction is imminent.
2.Overview of Metro Monitoring System
Based on the close combination of technologies such as the Internet of Things, cloud computing and big data, we will use the innovative application of Internet+ in subway monitoring to establish a subway automation monitoring platform to form a regional demonstration effect and open up a new era of automated monitoring of the entire subway line.
3.Metro Monitoring’s main monitoring content
1.Subway foundation pit: settlement and horizontal displacement at the top of the enclosed pile (wall), deep horizontal displacement of the enclosed pile (wall), internal force of the enclosed pile (wall), deep horizontal displacement of the soil outside the pit, anchor shaft force, groundwater level, support shaft force, pit bottom up
2.Subway Tunnel:
① Shield structure method: pipe sheet clearance convergence and pipe sheet structural stress
②Mine method: vault settlement and convergence, blasting vibration, vertical displacement of the central column structure, groundwater level
3.Peripheral risk sources: surface settlement, pipeline settlement, building inclination, uneven settlement of buildings, building cracks, piers inclination, uneven settlement of bridge piers

6.Metro Monitoring implementation functions
1.Online subway monitoring during the construction period: Compare the monitoring data with the design value, judge whether the construction technology and construction parameters meet the expected requirements, predict possible dangers in advance and take necessary engineering measures.Ensure the smooth progress of the project and ensure the quality and safety of construction.
2.Online subway monitoring during operation: realize continuous and accurate monitoring of interval horizontal and vertical displacements, so as to master the characteristics and laws of interval deformation during operation of the subway, and achieve the purpose of information monitoring.When the change value exceeds the preset value, you can have a timely warning.
