In order to avoid the occurrence of accidents, what problems should be paid attention to in the construction of tower crane infrastructure?
Tower lifting is a lifting equipment with powerful capabilities and is widely used in construction, transportation and other industries. Because it is composed of huge steel structures, the stability of the tower hanging foundation is of great importance. In the tower hanging accident, the collapse of the tower hanging occupies a large proportion, and the reason is caused by the unqualified foundation of the tower hanging.
So, in order to avoid the occurrence of Tower hanging accidents, tower hanging infrastructure should pay attention to what issues?

There are three types of reasons for tower crane basic accidents:
In order to rush the construction period, part of the site was hastily installed in the absence of concrete strength, so that the tower's hanging weight exceeded the limit of the ground stress, and an unfortunate incident of collapse and tipping occurred
The excavation work of some construction units near the tower hanging foundation led to landslides and even displacement triggered tower hanging accidents;

Due to the excessive groundwater extraction in many cities in China in recent years, groundwater funnels have been generated, which has caused uneven settlement and affected the operation and construction of Tower cranes.
Therefore, in order to prevent the collapse of the tower crane, the construction unit must ensure that the ground endurance meets the design requirements when making the tower crane foundation.
The strength of the reinforced concrete reaches at least 80 % of the design value. Special treatment measures should also be taken for the foundation of the tower with basement works: for example, piling under the foundation and welding the steel bars at the end of the pile with the foundation foot bolts firmly.
Concrete foundation should be flat and compacted, the bottom of the foundation can not be made into a pot bottom. The size error of the foundation foot bolt must be strictly in accordance with the requirements of the base diagram. The foot bolt must maintain a sufficient length of the ground surface, and each foot bolt must be pre-tightened with a double nut.

The base surface must be processed before installation to ensure that the level of the foundation can not exceed 1/1000. At the same time, the tower hanging foundation must not accumulate water, which will cause uneven settlement of the tower hanging foundation. In the vicinity of the tower hanging foundation, do not dig pits or ditch at will.
