Tower Crane Knowledge sharing:

Common practice and recommended practice of tower crane foundation

The common practice of the foundation of the rail-type tower crane is: first, the foundation shall be rammed or a layer of 37: lime soil cushion shall be made, then the gravel track slag shall be laid, and then the wooden sleeper shall be placed and the steel rail shall be laid on the wooden sleeper. This kind of practice is of great wood consumption and short service life, which is not suitable for heavy tower crane.

Today's recommended practice is to erect a reinforced concrete floor or a reinforced concrete sleeper beam on a rammed foundation, install a fixed i-beam on the floor or sleeper beam with embedded parts, and then install a rail on the i-beam. In order to improve the efficiency of rail laying and save the cost of rail laying, the reinforced concrete sleeper beam, i-beam steel support and rail are usually assembled together to form a 12.5m long prefabricated reinforced concrete rail foundation.

The bottom frame fixed jack-up tower crane is most suitable to adopt block type reinforced concrete foundation. On the foundation with high ground endurance, the size of this kind of concrete foundation plate can be 200 cm 200 cm 50 cm, and the top and bottom of the plate should be reinforced in both directions.

If the tower crane must be installed near the deep foundation pit, the cast-in-place pile cap foundation should be adopted to ensure the solidness and stability of the tower crane foundation, and measures should be taken to prevent the foundation pit slope from collapsing.

Two requirements must be met for the foundation of the fixed self-rising tower crane one is to transfer the upper load of the tower crane uniformly to the foundation and not exceed the ground endurance; The second is to make the tower crane in all kinds of adverse working conditions can maintain the overall stability without tipping. Therefore, this kind of tower crane foundation volume is quite huge, the foundation weight must be equal to the tower crane weight.

The foundation weight of the fixed tower crane is closely related to the free height of the tower crane. Take the FO/23 B tower crane as an example, when its free height is 59.8 m, the size of concrete foundation should reach 6.5 m 6.5 m 1.7 m.

If the tower crane needs to be erected near the deep foundation pit in the foundation construction stage, and the surface soil condition is poor, the foundation must also be supported by bored piles.

Therefore, in order to save the cost of foundation construction, it is advisable to decompose the whole mass concrete fou
