[Haichuan Civil Engineering Issues] Protection of foundation pit monitoring points
Thread Content
The foundation pit monitoring points are not protected. According to the \"Technical Standards for Monitoring of Building Foundation Pits\": 1. During the construction and operation period of the foundation pit, regular inspections must be carried out on a daily basis by designated personnel ； 2. Condition of reference points and monitoring points ； 3. Monitor the integrity and protection status of the components ； 4. Are there any obstacles that affect observation work?
In foundation pit construction, accidents occur from time to time due to the complexity and variability of rock and soil masses, the limitations of computational models, as well as errors in the design and construction processes, resulting in incalculable losses. Therefore, monitoring of foundation pit projects is not only an effective measure to achieve information-based construction and prevent accidents, but also an important means to improve and develop design theories and methods as well as enhance construction standards. The layout of monitoring points for foundation pit projects should reflect the actual condition of the monitored object and its trends of change. These monitoring points should be placed at key locations where internal forces and deformations occur, and they must meet the requirements for monitoring ； The placement of monitoring points should not interfere with the normal operation of the monitored objects, and should minimize any adverse effects on construction activities.
