Construction method for articulated gate shoe of pull rod of fan-shaped reinforcing steel bar penetrating arc door of gate pier

The invention discloses a construction method for an articulated gate shoe of a pull rod of a fan-shaped reinforcing steel bar penetrating arc door of a gate pier. The construction method comprises the following steps that (1) when fan-shaped reinforcing steel bars are connected to one another, the fan-shaped reinforcing steel bars which penetrate in second-stage concrete grooves of the articulated gate shoe and are blocked by the articulated gate shoe extend out of first-stage concrete and extend to second-stage concrete grooves of the articulated gate shoe by a certain overlapping length, and the overlapping length is determined according to standard requirements and does not affect installation of the articulated gate shoe; and the rest fan-shaped reinforcing steel bars which penetrate in the second-stage concrete grooves of the articulated gate shoe and are not blocked by the articulated gate shoe are directly connected to one another, and then first-stage concrete of the gate pier is poured; (2) a plural
