Embodiment Construction

[0045] A basement staged reverse construction method provided by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer in conjunction with the following description. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0046] like figure 1 As shown, the basement is constructed in stages after being separated by staged connecting walls 3 , and the basement includes at least the first-stage basement 1 and the second-stage basement 2 . In this embodiment, the basement 1 of the first phase adopts a steel structure, and horizontal steel beams 5 are arranged on the steel columns 9 , the basement 2 of the second phase adopts a reinforced concrete structure, and the p...

Abstract

The invention relates to a staged reverse construction method for a basement, belonging to the technical field of underground structure reverse construction. According to the construction method, the vertical force transmission structure and the staged ground connection wall construction are first carried out; then the steel columns, the B1 layer horizontal structure, the B0 layer horizontal structure and the B1 layer core tube are constructed in the basement to form a box load-bearing structure. ; Then use the reverse method to construct the remaining floors of the basement in sequence, and use the forward method to complete the construction of the shear wall of the basement core tube; finally, after the construction of the second phase of the basement is completed, the ground connecting walls are removed in stages from top to bottom, and the horizontal steel beams are completed Connect through. Among them, the load-bearing structure of the box body has better integrity and greater rigidity, and can smoothly transfer the stress of the above-ground structure to the steel columns and cast-in-situ piles below, preventing uneven settlement caused by large local pile foundation stress. problem, at the same time, the present invention also solves the problems of dismantling the connecting wall in stages and extending the butt joint of the horizontal steel beam.

Description

technical field [0001] The invention relates to a staged reverse construction method for a basement, belonging to the technical field of underground structure reverse construction. Background technique [0002] The upside-down construction technology of building basements has been widely used because of its two advantages of high safety and time saving, and has a good development prospect. At present, super high-rise buildings are mostly in the form of main building + podium, and the area of ​​the foundation pit is generally large. At the same time, taking into account factors such as site, safety and resources, the foundation pit of super high-rise buildings often needs to be divided into pits and phases by connecting walls in stages construction. After the construction of the basement adjacent to the foundation pit is completed, it is usually necessary to dismantle the enclosure structures such as the underground diaphragm wall in stages, so that the basement structures o...
