Steel pipe column tower crane foundation construction method

Abstract

The invention discloses a steel pipe column tower crane foundation construction method. The method comprises the following construction steps: S1, tower crane pile foundation construction; s2, a tower crane steel pipe column is pre-buried in the tower crane pile foundation construction process; s3, a bearing platform foundation is constructed on the tower crane steel pipe column; s4, tower crane installation is conducted on the bearing platform foundation; s5, foundation pit excavation is conducted within the working range of the tower crane; and S6, reinforcing the tower crane steel pipe column. The bottom surface of the tower crane foundation is arranged above the top plate structure of the underground garage, so that the tower crane installation and the foundation pit are constructed in parallel, the construction, installation and acceptance periods of the tower crane foundation are shortened, the tower crane can be put into use before the main body structure is constructed, and the production efficiency is improved; the bottom of the tower crane foundation is located above the top plate of the underground garage, the tower crane part and the bottom plate and the top plate of the underground garage can be poured at a time, the situation that in a traditional scheme, the bottom plate and the top plate of the tower body part need to be constructed again due to the fact that the tower body penetrates through the bottom plate and the top plate of the underground garage is reduced, construction procedures are reduced, and the construction period is shortened.

Description

technical field [0001] This patent application relates to the technical field of tower crane construction, in particular to a steel pipe column tower crane foundation construction method. Background technique [0002] For some comprehensive passenger transport hub projects, it is necessary to build underground garages below the ground. Such garages generally occupy a relatively large area, and the materials are completely transported by tower cranes, and the transportation task is arduous. The traditional tower crane construction sequence is that the tower crane foundation and tower crane installation and construction are carried out after the excavation of the foundation pit is completed, which leads to the inability to immediately enter the next process after the excavation of the foundation pit is completed. In addition, the tower crane foundation construction, tower crane installation, and acceptance period are long, and the normal commissioning time of the tower crane l...

AI Technical Summary

Problems solved by technology

The traditional construction sequence of the tower crane is that the tower crane foundation and tower crane installation and construction are carried out after the excavation of the foundation pit is completed, resulting in the inability to immediately enter the next process after the excavation of the foundation pit is completed

In addition, the tower crane foundation construction, tower crane installation, and acceptance period are long, and the normal commissioning time of the tower crane lags behind the construction production demand, which is extremely unfavorable for the construction production progress and node duration.
