Abstract

The invention discloses a construction method of pre-building a supported and settled foundation on ground and fixing after pre-pressing for a high-rise building with a basement. The method comprises the following steps: constructing the whole building including the basement on the ground in advance; arranging a grid supporter at the position of a structural base plate, wherein the grid supporter is used to transfer a vertical load of the building and balance the lateral pressure of the soil around an outer wall; arranging supporting piles which extend to the ground; arranging alternate force-transferring devices capable of being lifted and temporarily fixed between the supporting piles and the grid supporter, thereby moving the building downwards completely and stably; arranging a flexible cut waterproof curtain at the position of the outer wall of the basement, thereby reducing the downward cutting resistance of the outer wall during the downward moving process of the building; when the building moves downwards to a preset position, pre-pressing the construction piles one by one by utilizing the dead load of the building and a special loading device to finish the set settling of single piles in advance; loading a non-pile supporting building in blocks and finishing the set settling in advance; after the dead load of the upper building reaches a preset value, completely descending the building to a designed height; and pouring the base plate and finishing the final fixing of the building.

Description

technical field

[0001] The invention belongs to a brand-new construction method of high-rise buildings with multiple basements in the field of construction. It has changed the traditional process of foundation pit support, earthwork excavation, and then structural construction. It proposes that the structure including the basement be prefabricated on the ground, and the support piles extending to the ground are set as the support of the building. The lifting force transmission device gradually moves down the building to the predetermined elevation, during which the upper structure, electromechanical, decoration and other processes can be simultaneously carried out without interruption and continuous construction. A new construction method. Background technique

[0002] ①At present, in the construction of high-rise buildings with many basements, before the excavation of the basement earthwork, it is necessary to set up the corresponding temporary foundation pit support struct...

Embodiment Construction

[0027] The invention is a brand-new construction method applicable to multi-high-rise buildings with basements. The specific implementation steps are as follows:

[0028] 1. Early stage of construction: construct a flexible cuttable water-stop curtain 3 wider than the thickness of the wall along the perimeter of the basement exterior wall 1, construct concrete supporting piles 6 including steel lattice columns 7 according to the design position and elevation, and install detachable Install steel corbel 8-a and liftable force transmission device 9-a, adjust the top surface of liftable force transmission device 9-a to uniform elevation, level off the construction site, and facilitate ground pre-construction construction.

[0029] 2. Ground pre-construction: Construction of basement exterior wall edge 2 and grid support 4. After reaching strength and demoulding, grid support 4 is directly supported on the top surface of liftable force transmission device 9-a, and construction of ...
