Abstract

The invention relates to a tower crane foundation and a construction method thereof. The tower crane foundation comprises a first heightened beam, a second heightened beam, a tower crane bearing platform and anchoring feet, wherein the first heightened beam is arranged on an underground diaphragm wall, the second heightened beam is arranged on a roof of a basement, the tower crane bearing platform is arranged on the first heightened beam and the second heightened beam, and the anchoring feet are arranged on the tower crane bearing platform. A first steel bar is arranged in the first heightened beam. One end of the first steel bar is welded to a second steel bar in the underground diaphragm wall, and the other end of the first steel bar is anchored into the tower crane bearing platform. A plastic film is further laid between the bottom of the tower crane bearing platform and the roof of the basement. According to the tower crane foundation and the construction method thereof, a basement maintenance and permanent structure is used as the tower crane foundation, so that on the premise that a tower crane can meet the field construction requirement to the maximum extent, the construction cost is reduced, the construction difficulty is lowered, and the environmental friendliness purpose is achieved.

Description

technical field [0001] The invention belongs to the field of upper structure engineering, in particular to a tower crane foundation using basement enclosure and permanent structure as the foundation and a construction method thereof. Background technique [0002] The tower crane foundation can be divided into two types: mobile type and fixed type. The fixed tower foundation can be divided into the following two types according to the relationship between the bearing platform and its lower bearing layer: (1) Shallow foundation, where the platform is placed directly on the natural foundation (2) Pile foundation, using the existing supporting envelope to transfer the load of the cap. Since the layout of the tower crane is very important in the foundation pit construction stage, and the layout of the tower crane foundation is often limited by site conditions, the traditional layout method often has the following defects: [0003] First, for soft soil foundation pits, due to the...
