PLC synchronous jacking correction can be used for multi-storey buildings, high-rise buildings and ancient buildings to correct deviations, mainly using PLC synchronous jacking system to correct buildings, so what should be paid attention to when jacking correction?

Precautions for PLC synchronous jacking and correction

Precautions for PLC synchronous jacking and correction:

1. Analyze the building in advance to obtain the total bearing capacity of jacking, and then calculate the position and bearing capacity of each stress point;

2. Reinforce the foundation in advance to ensure the safety and reliability of the jacking link;

3. When the overall correction is corrected, attention should be paid to uniform progressive jacking;

4. Ensure the reliability of the reaction force system;

5. When the foundation deformation is not stable, the reinforcement and replacement of the foundation foundation should be considered.

6. During the jacking process, it is necessary to monitor the data in the correction process in real time and adjust the jacking status in time.

7. Calculate the secondary adjustment distribution of the internal force of the structure after the completion of the building correction to prepare for the next pressure sealing piles.

Monitoring instructions for the jacking and correction process:

Settlement monitoring: Settlement monitoring should measure the settlement value of the foundation and site ground, and calculate the foundation settlement difference, settlement rate, overall inclination, local inclination, relative bending and component inclination.

Tilt monitoring: The offset value and inclination direction of the observation point at the top of the building relative to the fixed point at the bottom or the upper floor relative to the observation point on the lower floor should be measured, and then the inclination rate and inclination rate of the main body of the building should be calculated according to the height of the building.

Site horizontal displacement monitoring: For tilt correction projects with complex terrain or geological conditions, site horizontal displacement monitoring should be carried out.

Crack monitoring: Cracks in buildings, surrounding surface cracks and cracks in surrounding buildings should be monitored, and the parts with large and representative crack widths should be selected as key observation objects.

Other monitoring: For important buildings, stress strain monitoring of important components can be carried out according to the construction plan; According to the construction plan of the tilt correction project, the groundwater level, adjacent buildings, underground pipelines, facilities, etc. are monitored.
