What should we do if we dig out foundations and find human bones?

Call the police first. In case of homicide or other cases, calling the police can exempt the deceased and give the deceased a fair chance.

Usually, the number of exploration holes is limited, and they are arranged at the midpoint of the four corners and the long side of the building's outer contour line. After the foundation trench is fully excavated, the soil layer of the foundation bearing layer will be completely exposed. First, check whether the survey results are consistent with the actual situation.

Whether the conclusions and suggestions of the survey results report are correct and feasible, whether the foundation soil layer reaches the soil layer according to the data given by the geological department at the time of design, and whether there is any difference. If there is any inconsistency, consultation should be carried out Solve, modify the design plan, or treat the foundation and other measures.

Whether the depth of the foundation reaches the design depth, whether the bearing layer is in place or over-excavated, whether the size of the foundation pit is correct, whether the axis position and deviation, and the size of the foundation meet the design requirements, whether there is water in the foundation pit, and whether the base soil layer Whether it was disturbed.

Solving remaining and newly discovered problems Sometimes the survey results report leaves behind problems that cannot be solved at the time. For example, when a geological survey unit was conducting geotechnical survey work on a student dormitory building, there was a resident on the site. , not allowing drilling into the courtyard became a remaining issue, which was later solved during the trench inspection.
