The foundation pit monitoring project of Chengfeng Road Electricity Channel Project is located in Zhengding New District of Shijiazhuang City, commissioned by the Municipal Engineering Bureau of Zhengding New District of Shijiazhuang City, our company undertook the third-party monitoring task of the foundation pit.
This monitoring began on October 17, 2020 and concluded on November 22, 2020 for 36 days. In total, we set up 8 monitoring points for horizontal and vertical displacements of the shaft, 12 monitoring points for vertical displacements of the ground surface around the shaft, 3 monitoring points for vertical displacements of the pipe jacking ground, and 27 monitoring points for large sections. After monitoring with total station and level meter, data processing is carried out according to the obtained data by using self-developed data processing software, meanwhile, safety patrol is carried out on the site and monitoring report is submitted as required. The foundation pit did not exceed the alarm values for displacement or rate of phase change from the beginning of the monitoring to the end of the monitoring. The foundation pit did not affect construction safety.
In October 2022, the data was completed and all results and technical reports were submitted, and the project successfully passed the owner's acceptance and completed the filing of the owner's data.
