在浇筑地下基础时，按设计确定的沉降观测点数与位置埋设好临时观测点，并进

When the underground foundation is poured, temporary observation points should be buried according to the number and location of settlement observation points determined by the design, and the first settlement observation should be carried out. The entire foundation should be poured no less than 2 times. When it reaches ±0.000, the permanent settlement observation point is buried according to the design requirements, and the observation is made every time one layer is increased or the load is increased to maintain the continuity of the settlement observation. After each observation, the unit of measurement calculates the settlement and the accumulated settlement, so as to grasp the average settlement and the differential settlement between points in time, and draw the measurement results into a settlement observation result table.

When pouring the underground foundation, the temporary observation points are laid according to the number and location of the settlement observation determined by design, and the first settlement observation is made, and the whole foundation shall be poured not less than 2 times. By ±0.000, permanent settlement observation points will be laid as required by design, with each additional layer or load increased to maintain the consistency of settlement observations. At the end of each observation, the unit of measurement calculates the amount of settlement and the cumulative amount of settlement, so as to grasp the average settling amount and the difference between points in time, and draw the measurement results into a sedimentation observation results table.

When pouring the underground foundation, the temporary observation points shall be buried according to the settlement observation points and positions determined in the design, and the first settlement observation shall be conducted. The whole foundation pouring shall be completed at least twice. When it reaches ± 0.000, the permanent settlement observation points shall be buried according to the design requirements, and the observation shall be conducted once for each additional layer or load, so as to maintain the continuity of settlement observation. After each observation, the settlement and cumulative settlement are calculated by the measuring unit, so as to grasp the average settlement and the differential settlement between each point in time, and draw the measurement results into the settlement observation results table.<br>
