Embodiment

[0020] In specific implementation, such as image 3 As shown, this example is applicable to the ultra-deep reverse engineering of the basement above three floors.

[0021] The principle is to use the basement permanent structure for tower crane installation. The construction sequence is as follows: pile foundation construction → steel pipe column construction → basement roof construction → tower crane foundation construction → steel tower crane installation and use. The specific construction steps are as follows:

[0022] 1. Carry out the pile foundation 1 construction according to the conventional method;

[0023] 2. Carry out the construction of basement floor 7 and steel pipe column 2 according to conventional methods;

[0024] 3, carry out basement roof 3 constructions in the mode of the present invention, concrete steps are as follows:

[0025] 1) Installation of basement roof formwork;

[0026] 2) According to the requirements of the design unit for re...

Abstract

The invention discloses a basement tower crane foundation construction method and structure adopting a reverse construction method. The method comprises the steps as follows: a tower crane is directly mounted on a basement roof by means of a permanent basement structure; the basement roof is reinforced by a cross beam; and a tower crane foundation is constructed on the cross beam, and the tower crane foundation, the cross beam and the basement roof are connected into a whole through steel bars. At the early stage of design, permanent basement structure pile foundations, steel pipe columns and the basement roof are utilized, and through reexamination and checking calculation of an original design institute, a tower crane model meeting selection requirements is directly mounted on the basement roof for mounting construction. The basement tower crane foundation construction method and structure adopting the reverse construction method have the advantages as follows: the permanent basement structure is utilized, a tower crane foundation pile and a built-up steel column are omitted, reserved holes in the basement structure are reduced, secondary construction of the basement structure is reduced, the construction period is shortened, the potential safety hazard is reduced, the construction measurement expense is saved, and meanwhile, normal use of the tower crane and safety of the permanent basement structure are guaranteed.

Description

technical field [0001] The invention relates to a construction method and a structure of a basement tower crane foundation by a top-down method, and belongs to the technical field of tower crane foundation construction. Background technique [0002] With the continuous development of my country's construction industry, various building types continue to emerge, and there are more and more super-large and super-deep projects. In the reverse construction of conventional engineering, the most common tower crane installation method is to install the tower crane on the foundation of the basement floor; there is another installation method that first constructs the pile foundation according to the requirements of the tower crane, and then adopts a lattice structure for the space between the basement floor and the roof Steel column, raise the tower crane foundation to the level of the basement roof, and then install the tower crane on the lattice steel column. Both of the above tw...
