Problems solved by technology
If the deviation is too large to meet the specifications and design requirements, the deviation of the steel pipe column needs to be dealt with. Therefore, it is urgent to provide a reinforcement measure for the deviation of the steel pipe column after pouring, so as to solve the problem of insufficient bearing capacity of the steel pipe concrete column

Embodiment Construction
[0030] The core of the present invention is to provide a method for reinforcing and supporting concrete-filled steel pipe columns of the reverse method. In the method for reinforcing and supporting the concrete-filled steel pipe columns of the reverse method, a large-scale truss support system is provided without affecting the construction of the reverse method, so as to ensure that the structure of the reverse method is compatible with the structure. Stability of concrete filled steel tube columns.
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the pro...

The invention discloses a reverse construction method concrete-filled steel tubular column reinforcing and supporting method. The reverse construction method concrete-filled steel tubular column reinforcing and supporting method comprises the following steps that a steel truss is manufactured according to measured deviation information of a defective concrete-filled steel tubular column; the steeltruss is hoisted to a mounting position, and supporting legs of the steel truss are fixed to the first-layer plate surface; the defective concrete-filled steel tubular column is fixed to a steel truss connecting column; after construction is carried out to the position of a bottom plate, permanent reinforcement measures are carried out on the defective concrete-filled steel tubular column again;and the steel truss is removed. When the bearing capacity of the poured steel tubular column is insufficient, a large truss system is used for reinforcing the bearing capacity of the concrete-filled steel tubular column, the problem that the bearing capacity of the concrete-filled steel tubular column is insufficient is solved, construction is carried out under the condition that reverse construction method construction is not affected, the subsequent construction procedure of the reverse construction method is guaranteed, and a guarantee is provided for the project progress; and the deflection generated when the concrete-filled steel tubular column is hoisted is small and is close to a statically indeterminate structure, and the structural stability, safety and reliability are guaranteedunder the condition that the concrete-filled steel tubular column deviates.
Description
technical field [0001] The invention relates to the technical field of upside-down method construction, in particular to a method for reinforcing and supporting a concrete-filled steel tube column using the upside-down method. Background technique [0002] With the vigorous development of urban rail transit, the reverse approach has been widely used due to its safety, small impact on ground traffic, and high structural rigidity. However, the construction of the cover-excavation upside-down method requires the installation of permanent column piles and steel pipe columns. The steel pipe columns are also used as basement structural columns. For deeper buried depths, when the upside-down method is used for construction, the steel pipe columns are likely to cause deviations due to the influence of positioning accuracy. This kind of deviation is not easy to find during construction, and it will be too late when the problem is found during downward construction. If the deviation ...
