3 Problems In Deep Foundation Pit Construction Engineering

by Anchor S. Web Designer
  • Collapse of foundation pit slope.

The collapse usually occurs at the construction stage or just construction completion. Exploring its reason, most situations are happened without following designed demand. During the construction of the soil nail system, the cement slurry could be fully injected into the hollow channel of the anchor bar to make the quick connection of the anchor bar and the rock, which can prevent collapse.

  • The horizontal displacement of the slope is big.

The worse geological condition in the foundation pit is, the larger the horizontal displacement of the support structure and soil is. Generally, the soil body’s horizontal displacement is larger than the surrounding support structures. Facing this situation, underground construction should be stopped and stability should be reanalyzed, then treatment measures should be put forward.

  • Surrounding buildings deform.

During urban construction, many foundation pits are near buildings, once improper operation happens, surrounding buildings are prone to deformation. Generally speaking, buildings’ deformation is caused by foundation settlement, which will not only threaten people’s safety but also influence the construction of the foundation pit.

Sinorock self-drilling anchor bolts can be used as soil nail structures. It integrates drilling, grouting and anchoring, and the anchor bar does not need to be taken out after drilling, which avoids the phenomenon of hole collapse. The integrated function can effectively control the deformation and displacement of the surrounding rock and ensure the stability of the surrounding rock.
