Deep Foundation Excavation

The design, construction and monitoring technology of deep foundation excavation have become big difficulties gradually. The supporting and protecting wall can not only ensure normal construction and stability, but also prevent deformation, soil body moving and normal operation of surrounding buildings, roads and underground pipelines.

With the propulsion of reconstruction of old city, main high buildings are clustering in narrow and busy spaces, the construction conditions almost terrible. There are many permanent and public facilities, so it is very strict for stability and displacement control.

If deep foundation excavated in complex geological conditions, such as soft soil and high groundwater table areas, it is easy to happen slippage of soil body, instability of deep foundation, deflection of pile body, severe leakage and damage, which will cause great threat for security.

Nowadays, supporting structures are perfecting gradually and there are many methods to supporting deep foundation. One method is self drilling rock bolt, which is accepted by people increasingly.

Self drilling rock bolt can be installed and constructed in narrow spaces and it is quite simple to operate only by one person. Drilling, grouting and anchoring play a role at the same time, which is energy-saving and high-efficient.
