Abstract

The invention provides a cantilever-type tower crane foundation structure and a construction method thereof. Shape steel is utilized as cantilever bracket structures, the mounting position of a towercrane extends out of the reinforced concrete range from the interior of the reinforced concrete range for balancing the bending moment and shearing force which are transmitted to a foundation from thetower crane, and the problems that the plane position of the tower crane foundation is limited, and the periphery does not meet independent foundation arrangement are solved; prestressed steel bars are utilized as main force-bearing components of an anchoring structure, and shape steel brackets and a bearing platform are in frictional connection by applying pretension force; a reinforced concretestructure is adopted as a protection structure to lower the influence caused by a collision of external force to the shape steel brackets and protect against corrosion caused by the environmental influence; and through the structure, the arrangement difficulty of the tower crane is lowered, the construction size of the tower crane foundation is decreased to the greatest extent under the limited working condition, the distances between the tower crane and attachments are reduced, a tower crane wall-adhering structure is simplified, and practicability is high.

Description

technical field [0001] The invention relates to the field of tower crane installation and construction, in particular to a cantilever type tower crane foundation structure and a construction method suitable for water and restricted areas. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane", which is used to lift construction materials such as steel bars, corrugated wood, concrete, and steel pipes. Tower crane is an indispensable equipment on the construction site. [0003] In order to ensure the stability and safety of the tower crane, the tower crane is installed on the foundation of the tower crane. The foundation of the tower crane is usually composed of a large-sized concrete cap. Most of the existing tower crane foundations are made on site, and the production period is long. It is reused and needs to be removed after use, and the studs are difficult to remove, which is prone to safety...
