WHAT SHOULD BE PAID ATTENTION TO IN TOWER CRANE FOUNDATION CONSTRUCTION

Tower crane plays an extremely important role in the field of construction and transportation. In the analysis of the causes of tower crane accidents.

 it is not difficult to find that a considerable number of cases are related to the collapse of the tower crane, which shows that the qualified foundation construction of the tower crane is an indispensable part to ensure the safe construction.

Analysis of causes of accidents involving tower crane foundation,

One part of the site in order to seize the construction period, in the case of insufficient concrete strength and hasty installation, so that the tower crane bearing more than the limit of the ground stress, thus collapse, tipping over the unfortunate events

In some construction units, the excavation near the foundation of the tower crane results in landslide and even displacement, which leads to tower crane accident.

In recent years, the excessive pumping of groundwater in many cities in China has resulted in the formation of groundwater funnels, which have caused uneven subsidence and affected the operation and construction of tower cranes.

Matters needing attention in tower crane foundation construction,

To prevent the occurrence of these accidents, the construction unit in the tower crane foundation, must ensure that the endurance in line with the design requirements, the strength of reinforced concrete at least 80% of the design value.

For tower crane foundations with basement works, special measures should be taken, such as piling under the foundation, and welding the reinforcement at the pile end and the foundation foundation bolts together firmly.

The bottom of the concrete foundation shall be leveled and rammed, and the bottom of the foundation shall not be made into a pot bottom.

The size error of foundation bolts must be strictly in accordance with the requirements of the foundation drawing construction, foundation bolts to maintain sufficient length of the exposed ground, each foundation bolts to double nut pre-tightening.

The surface of the foundation shall be treated before installation to ensure that the levelness of the foundation shall not exceed 1/1000. At the same time, the tower crane foundation shall not accumulate water, which will cause uneven settlement of the tower crane foundation.
