Main contents of subway construction monitoring

Steel structure stress monitoring, large-scale construction engineering stress change monitoring, structural health monitoring, etc.

Common types of construction monitoring include steel structure stress monitoring, large-scale construction engineering stress change monitoring, structural health monitoring, foundation pit monitoring, mass concrete pouring temperature monitoring, track monitoring, dock monitoring, tunnel surrounding rock displacement monitoring and so on.

Through monitoring and measurement, we can understand the dynamic changes of strata and supporting structures in each construction stage and master the safety state of the project itself during the construction process. Through understanding the influence of construction on the surrounding environment, according to the processing and analysis results of monitoring data, engineering measures are taken to control the surface subsidence, so as to ensure the smooth traffic on the ground and the normal use of ground buildings and underground pipelines.

Extended data:

Relevant requirements for construction monitoring stipulate that:

1. The working pressure of refrigeration system and brine system is directly measured by the pressure gauge installed on the system. The temperature of refrigeration system and brine system is directly read by the installed thermometer or measured by the thermometer.

2, underground pipeline settlement monitoring points, with lOmm as cumulative alarm value, plus or minus 3 mm as daily alarm value. The cumulative settlement alarm of surrounding buildings is based on the alarm value of underground pipelines, and the differential settlement is calculated as the alarm value of building inclination rate 1/300.

3. Accumulate data and experience, and understand the influence of the project on the surrounding environment and the basic law of its own deformation (or stress) through monitoring and measurement, so as to provide reference and guidance for similar projects in the future.
