The invention discloses an integral construction method for a tangent circle s-shaped reverse bridge section. The integral construction method comprises the following steps that the tangent circle s-shaped reverse bridge section is divided into an upward tangent circle bridge section and a downward tangent circle bridge section in the tangential direction of two adjacent tangent circles; the upward tangent circular bridge section is constructed through an incremental launching method; after the upward tangent circular bridge section is constructed, the downward tangent circular bridge section is constructed at the adjacent end of the upward tangent circular bridge section by adopting a hoisting method; in order to solve the problem that the transverse width of a bridge pier is not enough in curve pushing at a pushing starting section, the top of a fixed support is widened to serve as a pushing platform, steel box girders are assembled and then placed on the pushing platform to be pushed and installed, then th
