Abstract

The invention provides a high pile bearing platform tower crane foundation reinforced structure which comprises a steel pipe pile, a bearing platform, a sleeve, a sleeve bottom plate and a connectingreinforcing bar. Concrete is poured in the steel pipe pile, one end of the connecting reinforcing bar is fixed into the bearing platform, the other end of the connecting reinforcing bar is fixed intothe sleeve, the steel pipe pile is sleeved with the sleeve, the sleeve bottom plate is fixed to the bottom of the sleeve, the sleeve bottom plate is fixed to the outer wall of the steel pipe pile, thewall of the sleeve is provided with a grouting hole, the grouting hole is connected with a grouting pipe, and the bearing platform and the steel pipe pile are fixed in the mode that grouting materials are injected by the grouting pipe into the sleeve. By means of the reinforced structure, the antidumping performance and distortion resistance of a tower crane pile can be greatly improved, construction steps are simplified, operation is easy and convenient, the construction labor cost is saved, certain economic benefits can be created for construction units, and relevant requirements for environmentally-friendly construction are greatly met.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for a high pile cap tower crane foundation reinforcement structure. Background technique [0002] With the rapid increase of urban population, urban land is very precious, urban buildings are developing towards high-rise and super-high-rise and large-scale, and the underground part is getting bigger and deeper. The original floor-standing tower crane foundation construction can no longer Adapted to the requirements of the project on the construction period. The floor-type tower crane foundation needs to be constructed after earthwork excavation, resulting in the disadvantage of prolonging the construction period. For the suspended tower crane foundation, the tower crane pile foundation cap is constructed in advance, and the tower crane foundation is reinforced to enhance the overturning and twisting resistance.
