Description :
The observation period for general buildings can start after the foundation is completed or the basement is built, while for large and high-rise buildings, observation can start after the foundation cushion or foundation bottom is completed. The number of observations and interval time should depend on the foundation and loading conditions. Civil buildings can be observed once every 1-5 floors of height increase; Industrial buildings can be observed separately according to different construction stages, such as backfilling foundation pits, installing columns and roof trusses, masonry walls, equipment installation, etc. If the building is uniformly raised, it should be observed at least once when the load is increased by 25%, 50%, 75%, and 100%. If the construction process is temporarily suspended, observation should be conducted once during the suspension and once again during the resumption of work. If there is a sudden increase or decrease in ground load near the foundation, a large amount of water collection around the foundation, or prolonged continuous rainfall, the number of observations should be increased in a timely manner. When a building suddenly experiences significant settlement, uneven settlement, or severe cracks, continuous observations should be conducted immediately on a daily or daily basis. If the settlement is still unstable after the completion of the building, observation should continue during the use phase. Judgment of settlement stability: In general observation projects, if the settlement rate is less than 0.01-0.04mm/day, it can be considered that the settlement stability stage has been entered. The construction of the second underwater tunnel project in Jiaozhou Bay, Qingdao, has officially started on the main line at the Huangdao end! It is reported that the second tunnel of Jiaozhou Bay in Qingdao held a groundbreaking ceremony on October 29, 2020, with a planned total construction period of 72 months. Among them, the length of the main tunnel is 15.89 kilometers! The deepest point of the tunnel is 115 meters above sea level! After completion, it will become the world's longest underwater highway tunnel! The second underwater tunnel project in Jiaozhou Bay, Qingdao, starts at 380m east of the intersection of Huaihe East Road and Qianshan South Road in Huangdao District.
