How to build a tower crane foundation that is sturdy
Thread Content
With the rapid development of the modern economy, the use of tower cranes has become increasingly widespread and frequent. In recent years, there have been numerous safety accidents involving tower cranes. According to official statistics, a weak foundation is the main cause of such accidents. To minimize safety accidents caused by weak foundations in tower cranes, how should construction firms ensure that the foundations of these cranes are built firmly? First, before installing the tower crane, it is necessary to ensure that the bearing capacity of the ground meets the requirements for a solid foundation; the strength of the reinforced concrete should be at least around 80% of the designed value. If there is a tower crane foundation for basement works, special treatment measures are also required. Before installing the tower crane, the foundation surface should also be treated to ensure that its levelness does not exceed 1/1000. Secondly, the bottom surface of the concrete foundation must be level and compacted, and the precision of the foundation anchor bolts for the tower crane must be ensured in strict accordance with the construction requirements. In areas with heavy rainfall, it is necessary to ensure that there is no water accumulation around the foundation of the tower crane, as such accumulation can cause abnormalities such as settlement of the foundation. It is strictly prohibited to dig pits or trenches arbitrarily near the tower crane foundation.
