Embodiment Construction
[0041] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0042] See figure 1 , which is a flow chart of an embodiment of the HPE hydraulic construction method of the steel pipe column in the basement of the present invention, and it includes the following steps:
[0043] S1, harden the ground around the installation hole, and pour the concrete foundation platform.
[0044] see in conjunction figure 2 , before the installation hole (that is, the hole for pouring the foundation pile and the hole inserted into the steel pipe column) is opened, the foundation platform 1 can be poured on the ground within a certain range of the outer diameter of the installation hole (the outer diameter of the installation hole is preferably 1.2m), and hardened. To install the HPE hydraulic press and bear the weight of the HPE hydraulic press, so as to prevent the HPE hydraulic press from tilting due to ground depressions. The base platform...

The invention provides a reverse HPE (hydraulic perpendicular embedding) construction method for steel pipe columns in a basement, which includes the steps: a, casting a foundation pile below a mounting hole; b, pouring mud into the mounting hole; c, mounting and positioning an HPE hydraulic machine; d, perpendicularly lifting a steel pipe column to the HPE hydraulic machine; e, using the HPE hydraulic machine to drive the steel pipe column into the mounting hole and inserting the same into the foundation pile; f, spreading gravels around the steel pipe column for filling; and g, pouring concrete into the core of the steel pipe column. By the reverse HPE construction method, the quality of steel pipe column construction is high, construction period is short, and perpendicularity of the steel pipe column can be guaranteed effectively.
Description
technical field [0001] The invention relates to a HPE hydraulic construction method of a steel pipe column with a reverse method in a basement, in particular to a hydraulic construction method of a steel pipe column with a reverse method for a high-rise and super high-rise basement. Background technique [0002] With the rapid development of my country's construction industry, the upside-down construction of basements of high-rise and super high-rise buildings has gradually increased, which has become a development trend in the future. Among them, steel pipe columns have been widely used as upside-down permanent structural support technology. [0003] Among them, the construction of steel pipe columns will directly affect the construction quality of permanent structural steel pipe columns due to factors such as heavy steel pipe columns, high verticality requirements, high positioning accuracy, and difficult hoisting. [0004] The patent application of the Chinese application...
