Problems solved by technology

[0003] However, the existing tower crane foundation is fixed on the construction site and cannot be reused. After the construction is completed, it will become engineering waste or be completely dismantled and transported, resulting in construction waste, causing waste and environmental pollution, and there is still room for improvement.

Embodiment 1

[0039] A tower crane foundation structure, refer to figure 1 as well as figure 2 , including several pile bodies 2 sunk into the bottom of the basement 1 along the vertical direction, the top of the pile bodies 2 is connected with a tower crane installation platform 3, and the basement 1 is filled with a dense soil layer.

[0040] Part of the pile body 2 sinks into the soil at the bottom of the basement 1, and part of it is located in the cavity of the basement 1. The height of the top of the pile body 2 is lower than that of the top of the basement 1. The side walls of the pile body 2 located in the basement 1 are provided with a number of bearings. The load-bearing member 21 is a load-bearing rod 22 extending radially outward along the pile body 2, and a plurality of load-bearing rods 22 are evenly distributed around the circumference of the pile body 2 in the horizontal direction to form a load-bearing portion 23. There are multiple force parts 23 and they are evenly dist...

Abstract

The invention relates to the technical field of buildings, and provides a tower crane base structure and a construction method thereof so as to solve the problem that an existing tower crane base structure can not be used repeatedly. The tower crane base structure can be disassembled wholly and used repeatedly. According to the technical scheme, the tower crane base structure comprises a pluralityof pile bodies and a tower crane mounting platform; the pile bodies sink into the bottom of a basement; the tower crane mounting platform is connected with the pile tops; and the basement is filled with a compact soil layer. The construction method of the tower crane base structure comprises the following steps that (1) the basement is excavated, and the basement side wall is poured; (2) the pilebodies sink into the bottom of the basement; (3) the basement is backfilled to the pile top height; (4) the tower crane mounting platform is mounted; and (5) the basement is backfilled to a basementtop elevation. The basement is filled with the compact soil layer, so that the pile bodies have higher pulling and pressure resistance and bending resistance; and by excavating the soil layer in the basement, the tower crane base structure can be dismounted wholly and be used repeatedly, the disassembly is facilitated, and project waste is reduced.

Description

technical field [0001] The invention relates to the technical field of construction, more specifically, it relates to a tower crane foundation structure and a construction method thereof. Background technique [0002] Fixed tower cranes are widely used in modern industrial and civil buildings, and are mainly used to solve the problem of vertical transportation in building construction. In order to ensure the normal and safe operation of the tower crane, the tower crane must be fixed on the tower crane foundation, so the tower crane foundation must have sufficient strength, overturning resistance and shear resistance, and the tower crane foundation must not damage the foundation structure of the building facilities. [0003] However, the existing tower crane foundation is fixed on the construction site and cannot be reused. After the construction is completed, it will become engineering waste or be completely dismantled and transported, resulting in construction waste, causin...
