Tower Crane, is an important lifting equipment on the construction site, the application of tower crane is very extensive In the transportation, logistics and other industries also play an important role. Many tower crane accidents are caused by tower crane overturning, which shows that building tower crane foundation is an important guarantee for safe construction. According to an analysis by http://www.fx68.net , there are three types of accidents caused by tower crane foundations: First, some construction sites are hastily installed in order to meet the construction schedule, and the concrete strength is not enough, which causes the tower crane to carry more weight than the ground stress limit The two excavations near the foundation of the tower crane lead to the landslide and even the displacement of the tower crane, which lead to the tower crane accident In recent years, many cities in China draw too much groundwater, resulting in groundwater funnel, and then lead to uneven settlement, affecting the operation and construction of tower crane. Therefore, to prevent these tower crane accidents, construction units in the Tower Crane Foundation, must ensure that the ground resistance to meet the design requirements, reinforced concrete strength of at least 80% of the design value. The Tower Crane Foundation with basement engineering should take special treatment measures, such as piling under the foundation, and welding the steel bar at the end of the pile to the foundation foundation anchor bolt.

 The bottom of the concrete foundation should be tamped smoothly, and the bottom of the foundation can not be made into a pot bottom. Base anchor bolt size error must be strictly in accordance with the requirements of the foundation map construction, anchor bolt to maintain sufficient length exposed to the ground, each anchor bolt to double-nut pre-tightening. Before installation, the foundation surface should be treated to ensure that the level of the foundation can not exceed 1 / 1000. At the same time, the foundation of the Tower Crane shall not accumulate water, which will cause uneven settlement of the foundation. No digging or trenching shall be allowed in the vicinity of the foundation of the tower crane.
