The technical problem of the invention is mainly solved by the following technical scheme:
the reverse assembling method of the variable cross-section steel pipe forked support column comprises the following operation steps:
the first step is as follows: and (2) drilling deep holes in the foundation to embed the flanged steel reinforcement cage into the foundation, drilling cement injection holes on two sides of the steel reinforcement cage, drilling a communicating channel between the cement injection holes and the steel reinforcement cage, and connecting and fixing the anti-seismic spherical hinged support and the steel reinforcement cage by adopting a flange type bolt.
The second step is that: and connecting the nodes of the support columns with the bifurcate columns on the end surfaces, and then welding and fixing the connecting rods among the bifurcate columns.
The third step: and hoisting the connecting structure of the supporting column node and the bifurcated column, and then installing the steel pipe concrete column to complete the installation and forming of the variable cross-section steel pipe bifurcated supporting column.
The fourth step: and erecting a pile driver on the cement injection hole, and injecting concrete in the cement injection hole into the steel reinforcement cage from the communicating channel through the pile driver.
Preferably, the opening of the cement injection hole is provided with an inclined flaring, so that cement and concrete can be conveniently injected into the cement injection hole by a cement mixer truck.
Preferably, after the steel pipe concrete column is installed, the steel pipe concrete column is poured to the top of the column.
Preferably, when the steel pipe concrete column is installed, the steel pipe concrete column is firstly welded with the supporting column node, and then the steel pipe concrete column is connected with the anti-seismic spherical hinged support through a column bottom welding line.
